Joachim Breitner: Verifying the code of the Internet Identity service

The following post was meant to be posted at https://forum.dfinity.org/, but that discourse instance didn t like it; maybe too much inline code, so I m posting it here instead. To my regular blog audience, please excuse the lack of context. Please comment at the forum post. The text was later also posted on the DFINITY medium blog You probably have used https://identity.ic0.app/ to log into various applications (the NNS UI, OpenChat etc.) before, and if you do that, you are trusting this service to take good care of your credentials. Furthermore, you might want to check that the Internet Identity is really not tracking you. So you want to know: Is this really running the code we claim it to run? Of course the following applies to other canisters as well, but I ll stick to the Internet Identity in this case. I ll walk you through the steps of verifying that:

Find out what is running A service on the Internet Computer, i.e. a canister, is a WebAssembly module. The Internet Computer does intentionally not allow you to just download the Wasm code of any canisters, because maybe some developer wants to keep their code private. But it does expose a hash of the Wasm module. The easiest way to get it is using dfx: 
$ dfx canister --no-wallet --network ic info rdmx6-jaaaa-aaaaa-aaadq-cai
Controller: r7inp-6aaaa-aaaaa-aaabq-cai
Module hash: 0xd4af9277f3e8d26fd8cdc7874a9f47b6456587fbb2a64d61b6b6880d144d3c04
The controller here is the canister id of the governance canister. This tells you that the Internet Identity is controlled by the Network Nervous System (NNS), and its code can only be changed via proposals that are voted on. This is good; if the controller was just, say, me, I could just change the code of the Internet Identity and take over all your identities. The Module hash is the SHA-256 hash of the .wasm that was deployed. So let s follow that trace.

Finding the right commit Since upgrades to the Internet Identity are done via proposals to the NNS, we should find a description of such a proposal in the https://github.com/ic-association/nns-proposals repository, in the proposals/network_canister_management directory.
Github s list of recent NNS proposalsGithub s list of recent NNS proposals
We have to find the latest proposal upgrading the Internet Identity. The folder unfortunately contains proposals for many canisters, and the file naming isn t super helpful. I usually go through the list from bottom and look at the second column, which contains the title of the latest commit creating or modifying a file. In this case, the second to last is the one we care about: https://github.com/ic-association/nns-proposals/blob/main/proposals/network_canister_management/20210527T2203Z.md. This file lists rationales, gives an overview of changes and, most importantly, says that bd51eab is the commit we are upgrading to. The file also says that the wasm hash is d4a c04, which matches what we saw above. This is good: it seems we really found the youngest proposal upgrading the Internet Identity, and that the proposal actually went through. WARNING: If you are paranoid, don t trust this file. There is nothing preventing a proposal proposer to create a file pointing to one revision, but actually including other code in the proposal. That s why the next steps are needed.

Getting the source Now that we have the revision, we can get the source and check out revision bd51eab: 
/tmp $ git clone https://github.com/dfinity/internet-identity

/tmp/internet-identity $ git log --oneline -n 1
bd51eab (HEAD, tag: mainnet-20210527T2203Z) Registers the seed phrase before showing it (#301)
In the last line you see that the Internet Identity team has tagged that revision with a tag name that contains the proposal description file name. Very tidy!

Reproducing the build The README.md has the following build instructions:

Official build The official build should ideally be reproducible, so that independent parties can validate that we really deploy what we claim to deploy. We try to achieve some level of reproducibility using a Dockerized build environment. The following steps should build the official Wasm image 
docker build -t internet-identity-service .
docker run --rm --entrypoint cat internet-identity-service /internet_identity.wasm > internet_identity.wasm
sha256sum internet_identity.wasm
The resulting internet_identity.wasm is ready for deployment as rdmx6-jaaaa-aaaaa-aaadq-cai, which is the reserved principal for this service.

It actually suffices to run the first command, as it also prints the hash (we don t need to copy the .wasm out of the Docker canister): 
/tmp/internet-identity $ docker build -t internet-identity-service .
 
Step 26/26 : RUN sha256sum internet_identity.wasm
 ---> Running in 1a04644b544c
d4af9277f3e8d26fd8cdc7874a9f47b6456587fbb2a64d61b6b6880d144d3c04  internet_identity.wasm
Removing intermediate container 1a04644b544c
 ---> bfe6a63a7980
Successfully built bfe6a63a7980
Successfully tagged internet-identity-service:latest
Success! The hashes match. You don t believe me? Try it yourself (and let us know if you get a different hash, maybe I got hacked). This may fail if you have too little RAM configured for Docker, 8GB should be enough. At this point you have a trust path from the code sitting in front of you to the Internet Identity running at https://identity.ic0.app, including the front-end code, and you can start auditing the source code.

What about the canister id? If you payed close attention you might have noticed that we got the module has for canister rdmx6-jaaaa-aaaaa-aaadq-cai, but we are accessing a web application at https://identity.ic0.app. So where is this connection? In the future, I expect some form of a DNS-like nice host name registry on the Internet Computer that stores a mapping from nice names to canister ids, and that you will be able to query that to for which canister serves rdmx6-jaaaa-aaaaa-aaadq-cai in a secure way (e.g. using certified variables). But since we don t have that yet, but still want you to be able to use a nice name for the Internet Identity (and not have to change the name later, which would cause headaches), we have hard-coded this mapping for now. The relevant code here is the Certifying Service Worker that your browser downloads when accessing any *.ic0.app URL. This piece of code will then intercept all requests to that domain, map it to an query call, and then use certified variables to validate the response. And indeed, the mapping is in the code there: 
const hostnameCanisterIdMap: Record<string, [string, string]> =  
  'identity.ic0.app': ['rdmx6-jaaaa-aaaaa-aaadq-cai', 'ic0.app'],
  'nns.ic0.app': ['qoctq-giaaa-aaaaa-aaaea-cai', 'ic0.app'],
  'dscvr.ic0.app': ['h5aet-waaaa-aaaab-qaamq-cai', 'ic0.page'],
 ;

What about other canisters? In principle, the same approach works for other canisters, whether it s OpenChat, the NNS canisters etc. But the details will differ, as every canister developer might have their own way of
  • communicating the location and revision of the source for their canisters
  • building the canisters
In particular, without a reproducible way of building the canister, this will fail, and that s why projects like https://reproducible-builds.org/ are so important in general.

Matthew Garrett: Producing a trustworthy x86-based Linux appliance

Let's say you're building some form of appliance on top of general purpose x86 hardware. You want to be able to verify the software it's running hasn't been tampered with. What's the best approach with existing technology?

Let's split this into two separate problems. The first is to do as much as we can to ensure that the software can't be modified without our consent[1]. This requires that each component in the boot chain verify that the next component is legitimate. We call the first component in this chain the root of trust, and in the x86 world this is the system firmware[2]. This firmware is responsible for verifying the bootloader, and the easiest way to do this on x86 is to use UEFI Secure Boot. In this setup the firmware contains a set of trusted signing certificates and will only boot executables with a chain of trust to one of these certificates. Switching the system into setup mode from the firmware menu will allow you to remove the existing keys and install new ones.

(Note: You shouldn't use the trusted certificate directly for signing bootloaders - instead, the trusted certificate should be used to sign another certificate and the key for that certificate used to sign your bootloader. This way, if you ever need to revoke the signing certificate, you can simply sign a new one with the trusted parent and push out a revocation update instead of having to provision new keys)

But what do you want to sign? In the general purpose Linux world, we use an intermediate bootloader called Shim to bridge from the Microsoft signing authority to a distribution one. Shim then verifies the signature on grub, and grub in turn verifies the signature on the kernel. This is a large body of code that exists because of the use cases that general purpose distributions need to support - primarily, booting on arbitrary off the shelf hardware, and allowing arbitrary and complicated boot setups. This is unnecessary in the appliance case, where the hardware target can be well defined, where there's no need for interoperability with the Microsoft signing authority, and where the boot configuration can be extremely static.

We can skip all of this complexity using systemd-boot's unified Linux image support. This has the format described here, but the short version is that it's simply a kernel and initramfs linked into a small EFI executable that will run them. Instructions for generating such an image are here, and if you follow them you'll end up with a single static image that can be directly executed by the firmware. Signing this avoids dealing with a whole host of problems associated with relying on shim and grub, but note that you'll be embedding the initramfs as well. Again, this should be fine for appliance use-cases, but you'll need your build system to support building the initramfs at image creation time rather than relying on it being generated on the host.

At this point we have a single image that can be verified by the firmware and will get us to the point of a running kernel and initramfs. Unless you've got enough RAM that you can put your entire workload in the initramfs, you're going to want a filesystem as well, and you're going to want to verify that that filesystem hasn't been tampered with. The easiest approach to this is to use dm-verity, a device-mapper layer that uses a hash tree to verify that the filesystem contents haven't been modified. The kernel needs to know what the root hash is, so this can either be embedded into your initramfs image or into the kernel command line. Either way, it'll end up in the signed boot image, so nobody will be able to tamper with it.

It's important to note that a dm-verity partition is read-only - the kernel doesn't have the cryptographic secret that would be required to generate a new hash tree if the partition is modified. So if you require the ability to write data or logs anywhere, you'll need to add a new partition for that. If this partition is unencrypted, an attacker with access to the device will be able to put whatever they want on there. You should treat any data you read from there as untrusted, and ensure that it's validated before use (ie, don't just feed it to a random parser written in C and expect that everything's going to be ok). On the other hand, if it's encrypted, remember that you can't just put the encryption key in the boot image - an attacker with access to the device is going to be able to dump that and extract it. You'll probably want to use a TPM-sealed encryption secret, which will be discussed later on.

At this point everything in the boot process is cryptographically verified, and so should be difficult to tamper with. Unfortunately this isn't really sufficient - on x86 systems there's typically no verification of the integrity of the secure boot database. An attacker with physical access to the system could attach a programmer directly to the firmware flash and rewrite the secure boot database to include keys they control. They could then replace the boot image with one that they've signed, and the machine would happily boot code that the attacker controlled. We need to be able to demonstrate that the system booted using the correct secure boot keys, and the only way we can do that is to use the TPM.

I wrote an introduction to TPMs a while back. The important thing to know here is that the TPM contains a set of Platform Configuration Registers that are large enough to contain a cryptographic hash. During boot, each component of the boot process will generate a "measurement" of other security critical components, including the next component to be booted. These measurements are a representation of the data in question - they may simply be a hash of the object being measured, or the hash of a structure containing various pieces of metadata. Each measurement is passed to the TPM, along with the PCR it should be measured into. The TPM takes the new measurement, appends it to the existing value, and then stores the hash of this concatenated data in the PCR. This means that the final PCR value depends not only on the measurement, but also on every previous measurement. Without breaking the hash algorithm, there's no way to set the PCR to an arbitrary value. The hash values and some associated data are stored in a log that's kept in system RAM, which we'll come back to later.

Different PCRs store different pieces of information, but the one that's most interesting to us is PCR 7. Its use is documented in the TCG PC Client Platform Firmware Profile (section 3.3.4.8), but the short version is that the firmware will measure the secure boot keys that are used to boot the system. If the secure boot keys are altered (such as by an attacker flashing new ones), the PCR 7 value will change.

What can we do with this? There's a couple of choices. For devices that are online, we can perform remote attestation, a process where the device can provide a signed copy of the PCR values to another system. If the system also provides a copy of the TPM event log, the individual events in the log can be replayed in the same way that the TPM would use to calculate the PCR values, and then compared to the actual PCR values. If they match, that implies that the log values are correct, and we can then analyse individual log entries to make assumptions about system state. If a device has been tampered with, the PCR 7 values and associated log entries won't match the expected values, and we can detect the tampering.

If a device is offline, or if there's a need to permit local verification of the device state, we still have options. First, we can perform remote attestation to a local device. I demonstrated doing this over Bluetooth at LCA back in 2020. Alternatively, we can take advantage of other TPM features. TPMs can be configured to store secrets or keys in a way that renders them inaccessible unless a chosen set of PCRs have specific values. This is used in tpm2-totp, which uses a secret stored in the TPM to generate a TOTP value. If the same secret is enrolled in any standard TOTP app, the value generated by the machine can be compared to the value in the app. If they match, the PCR values the secret was sealed to are unmodified. If they don't, or if no numbers are generated at all, that demonstrates that PCR 7 is no longer the same value, and that the system has been tampered with.

Unfortunately, TOTP requires that both sides have possession of the same secret. This is fine when a user is making that association themselves, but works less well if you need some way to ship the secret on a machine and then separately ship the secret to a user. If the user can simply download the secret via some API, so can an attacker. If an attacker has the secret, they can modify the secure boot database and re-seal the secret to the new PCR 7 value. That means having to add some form of authentication, along with a strong binding of machine serial number to a user (in order to avoid someone with valid credentials simply downloading all the secrets).

Instead, we probably want some mechanism that uses asymmetric cryptography. A keypair can be generated on the TPM, which will refuse to release an unencrypted copy of the private key. The public key, however, can be exported and stored. If it's acceptable for a verification app to connect to the internet then the public key can simply be obtained that way - if not, a certificate can be issued to the key, and this exposed to the verifier via a QR code. The app then verifies that the certificate is signed by the vendor, and if so extracts the public key from that. The private key can have an associated policy that only permits its use when PCR 7 has an appropriate value, so the app then generates a nonce and asks the user to type that into the device. The device generates a signature over that nonce and displays that as a QR code. The app verifies the signature matches, and can then assert that PCR 7 has the expected value.

Once we can assert that PCR 7 has the expected value, we can assert that the system booted something signed by us and thus infer that the rest of the boot chain is also secure. But this is still dependent on the TPM obtaining trustworthy information, and unfortunately the bus that the TPM sits on isn't really terribly secure (TPM Genie is an example of an interposer for i2c-connected TPMs, but there's no reason an LPC one can't be constructed to attack the sort usually used on PCs). TPMs do support encrypted communication channels, but bootstrapping those isn't straightforward without firmware support. The easiest way around this is to make use of a firmware-based TPM, where the TPM is implemented in software running on an ancillary controller. Intel's solution is part of their Platform Trust Technology and runs on the Management Engine, AMD run it on the Platform Security Processor. In both cases it's not terribly feasible to intercept the communications, so we avoid this attack. The downside is that we're then placing more trust in components that are running much more code than a TPM would and which have a correspondingly larger attack surface. Which is preferable is going to depend on your threat model.

Most of this should be achievable using Yocto, which now has support for dm-verity built in. It's almost certainly going to be easier using this than trying to base on top of a general purpose distribution. I'd love to see this become a largely push button receive secure image process, so might take a go at that if I have some free time in the near future.

[1] Obviously technologies that can be used to ensure nobody other than me is able to modify the software on devices I own can also be used to ensure that nobody other than the manufacturer is able to modify the software on devices that they sell to third parties. There's no real technological solution to this problem, but we shouldn't allow the fact that a technology can be used in ways that are hostile to user freedom to cause us to reject that technology outright.
[2] This is slightly complicated due to the interactions with the Management Engine (on Intel) or the Platform Security Processor (on AMD). Here's a good writeup on the Intel side of things.

David Bremner: Baby steps towards schroot and slurm cooperation.

Unfortunately schroot does not maintain CPU affinity 1. This means in particular that parallel builds have the tendency to take over an entire slurm managed server, which is kindof rude. I haven't had time to automate this yet, but following demonstrates a simple workaround for interactive building. 
  simplex:~
 % schroot --preserve-environment -r -c polymake
(unstable-amd64-sbuild)bremner@simplex:~$ echo $SLURM_CPU_BIND_LIST
0x55555555555555555555
(unstable-amd64-sbuild)bremner@simplex:~$ grep Cpus /proc/self/status
Cpus_allowed:   ffff,ffffffff,ffffffff
Cpus_allowed_list:      0-79
(unstable-amd64-sbuild)bremner@simplex:~$ taskset $SLURM_CPU_BIND_LIST bash
(unstable-amd64-sbuild)bremner@simplex:~$ grep Cpus /proc/self/status
Cpus_allowed:   5555,55555555,55555555
Cpus_allowed_list:      0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,62,64,66,68,70,72,74,76,78

Next steps In principle the schroot configuration parameter can be used to run taskset before every command. In practice it's a bit fiddly because you need a shell script shim (because the environment variable) and you need to e.g. goof around with bind mounts to make sure that your script is available in the chroot. And then there's combining with ccache and eatmydata...

Russ Allbery: Review: The Horse and His Boy

Review: The Horse and His Boy, by C.S. Lewis
Illustrator: Pauline Baynes
Series: Chronicles of Narnia #5
Publisher: Collier Books
Copyright: 1954
Printing: 1978
ISBN: 0-02-044200-9
Format: Mass market
Pages: 217
The Horse and His Boy was the fifth published book in the Chronicles of Narnia, but it takes place during the last chapter of The Lion, the Witch and the Wardrobe, in the midst of the golden age of Narnia. It's the only true side story of the series and it doesn't matter much where in sequence you read it, as long as it's after The Lion, the Witch and the Wardrobe and before The Last Battle (which would spoil its ending somewhat). MAJOR SPOILERS BELOW. The Horse and His Boy is also the only book of the series that is not a portal fantasy. The Pevensie kids make an appearance, but as the ruling kings and queens of Narnia, and only as side characters. The protagonists are a boy named Shasta, a girl named Aravis, and horses named Bree and Hwin. Aravis is a Calormene, a native of the desert (and extremely Orientalist, but more on that later) kingdom to the south of Narnia and Archenland. Shasta starts the book as the theoretically adopted son but mostly slave of a Calormene fisherman. The Horse and His Boy is the story of their journey from Calormen north to Archenland and Narnia, just in time to defend Narnia and Archenland from an invasion. This story starts with a great hook. Shasta's owner is hosting a passing Tarkaan, a Calormene lord, and overhears a negotiation to sell Shasta to the Tarkaan as his slave (and, in the process, revealing that he rescued Shasta as an infant from a rowboat next to a dead man). Shasta starts talking to the Tarkaan's horse and is caught by surprise when the horse talks back. He is a Talking Horse from Narnia, kidnapped as a colt, and eager to return to Narnia and the North. He convinces Shasta to attempt to escape with him. This has so much promise. For once, we're offered a story where one of the talking animals of Narnia is at least a co-protagonist and has some agency in the story. Bree takes charge of Shasta, teaches him to ride (or, mostly, how to fall off a horse), and makes most of the early plans. Finally, a story that recognizes that Narnia stories don't have to revolve around the humans! Unfortunately, Bree is an obnoxious, arrogant character. I wanted to like him, but he makes it very hard. This gets even worse when Shasta is thrown together with Aravis, a noble Calormene girl who is escaping an arranged marriage on her own talking mare, Hwin. Bree is a warhorse, Hwin is a lady's riding mare, and Lewis apparently knows absolutely nothing about horses, because every part of Bree's sexist posturing and Hwin's passive meekness is awful and cringe-worthy. I am not a horse person, so will link to Judith Tarr's much more knowledgeable critique at Tor.com, but suffice it to say that mares are not meekly deferential or awed by stallions. If Bree had behaved that way with a real mare, he would have gotten the crap beaten out of him (which might have improved his attitude considerably). As is, we have to put up with rather a lot of Bree's posturing and Hwin (who I liked much better) barely gets a line and acts disturbingly like she was horribly abused. This makes me sad, because I like Bree's character arc. He's spent his whole life being special and different from those around him, and while he wants to escape this country and return home, he's also gotten used to being special. In Narnia, he will just be a normal talking horse. To get everything else he wants, he also has to let go of the idea that he's someone special. If Lewis had done more with this and made Bree a more sympathetic character, this could have been very effective. As written, it only gets a few passing mentions (mostly via Bree being weirdly obsessed with whether talking horses roll) and is therefore overshadowed by Shasta's chosen one story and Bree's own arrogant behavior. The horses aside, this is a passable adventure story with some well-done moments. The two kids and their horses end up in Tashbaan, the huge Calormene capital, where they stumble across the Narnians and Shasta is mistaken for one of their party. Radagast, the prince of Calormen, is proposing marriage to Susan, and the Narnians are in the process of realizing he doesn't plan to take no for an answer. Aravis, meanwhile, has to sneak out of the city via the Tisroc's gardens, which results in her hiding behind a couch as she hears Radagast's plans to invade Archenland and Narnia to take Susan as his bride by force. Once reunited, Shasta, Aravis, and the horses flee across the desert to bring warning to Archenland and then Narnia. Of all the Narnia books, The Horse and His Boy leans the hardest into the personal savior angle of Christianity. Parts of it, such as Shasta's ride over the pass into Narnia, have a strong "Footprints" feel to them. Most of the events of the book are arranged by Aslan, starting with Shasta's early life. Readers of the series will know this when a lion shows up early to herd the horses where they need to go, or when a cat keeps Shasta company in the desert and frightens away jackals. Shasta only understands near the end. I remember this being compelling stuff as a young Christian reader. This personal attention and life shaping from God is pure Christian wish fulfillment of the "God has a plan for your life" variety, even more so than Shasta turning out to be a lost prince. As an adult re-reader, I can see that Lewis is palming the theodicy card rather egregiously. It's great that Aslan was making everything turn out well in the end, but why did he have to scare the kids and horses half to death in the process? They were already eager to do what he wanted, but it's somehow inconceivable that Aslan would simply tell them what to do rather than manipulate them. There's no obvious in-story justification why he couldn't have made the experience much less terrifying. Or, for that matter, prevented Shasta from being kidnapped as an infant in the first place and solved the problem of Radagast in a more direct way. This sort of theology takes as an unexamined assumption that a deity must refuse to use his words and instead do everything in weirdly roundabout and mysterious ways, which makes even less sense in Narnia than in our world given how directly and straightforwardly Aslan has acted in previous books. It was also obvious to me on re-read how unfair Lewis's strict gender roles are to Aravis. She's an excellent rider from the start of the book and has practiced many of the things Shasta struggles to do, but Shasta is the boy and Aravis is the girl, so Aravis has to have girl adventures involving tittering princesses, luxurious baths, and eavesdropping behind couches, whereas Shasta has boy adventures like riding to warn the king or bringing word to Narnia. There's nothing very objectionable about Shasta as a character (unlike Bree), but he has such a generic character arc. The Horse and Her Girl with Aravis and Hwin as protagonists would have been a more interesting story, and would have helpfully complicated the whole Narnia and the North story motive. As for that storyline, wow the racism is strong in this one, starting with the degree that The Horse and His Boy is deeply concerned with people's skin color. Shasta is white, you see, clearly marking him as from the North because all the Calormenes are dark-skinned. (This makes even less sense in this fantasy world than in our world because it's strongly implied in The Magician's Nephew that all the humans in Calormen came from Narnia originally.) The Calormenes all talk like characters from bad translations of the Arabian Nights and are shown as cruel, corrupt slavers with a culture that's a Orientalist mishmash of Arab, Persian, and Chinese stereotypes. Everyone is required to say "may he live forever" after referencing the Tisroc, which is an obvious and crude parody of Islam. This stereotype fest culminates in the incredibly bizarre scene that Aravis overhears, in which the grand vizier literally grovels on the floor while Radagast kicks him and the Tisroc, Radagast's father, talks about how Narnia's freedom offends him and the barbarian kingdom would be more profitable and orderly when conquered. The one point to Lewis's credit is that Aravis is also Calormene, tells stories in the same style, and is still a protagonist and just as acceptable to Aslan as Shasta is. It's not enough to overcome the numerous problems with Lewis's lazy world-building, but it makes me wish even more that Aravis had gotten her own book and more meaningful scenes with Aslan. I had forgotten that Susan appears in this book, although that appearance doesn't add much to the general problem of Susan in Narnia except perhaps to hint at Lewis's later awful choices. She is shown considering marriage to the clearly villainous Radagast, and then only mentioned later with a weird note that she doesn't ride to war despite being the best archer of the four. I will say again that it's truly weird to see the Pevensie kids as (young) adults discussing marriage proposals, international politics, and border wars while remembering they all get dumped back into their previous lives as British schoolkids. This had to have had dramatic effects on their lives that Lewis never showed. (I know, the real answer is that Lewis is writing these books according to childhood imaginary adventure logic, where adventures don't have long-term consequences of that type.) I will also grumble once more at how weirdly ineffectual Narnians are until some human comes to tell them what to do. Calormen is obviously a threat; Susan just escaped from an attempted forced marriage. Archenland is both their southern line of defense and is an ally separated by a mountain pass in a country full of talking eagles, among other obvious messengers. And yet, it falls to Shasta to ride to give warning because he's the human protagonist of the story. Everyone else seems to be too busy with quirky domesticity or endless faux-medieval chivalric parties. The Horse and His Boy was one of my favorites when I was a kid, but reading as an adult I found it much harder to tolerate Bree or read past the blatant racial and cultural stereotyping. The bits with Aslan also felt less magical to me than they did as a kid because I was asking more questions about why Aslan had to do everything in such an opaque and perilous way. It's still not a bad adventure; Aravis is a great character, the bits in Tashbaan are at least memorable, and I still love the Hermit of the Southern March and want to know more about him. But I would rank it below the top tier of Narnia books, alongside Prince Caspian as a book with some great moments and some serious flaws. Followed in original publication order by The Magician's Nephew. Rating: 7 out of 10

Dirk Eddelbuettel: inline 0.3.19: Another Update

A new release of the inline package got to CRAN today, following and further updating the recent update from earlier in the month. inline facilitates writing code in-line in simple string expressions or short files. The package was used quite extensively by Rcpp in the days before Rcpp Attributes arrived on the scene providing an even better alternative for its use cases. inline is still used by rstan and a number of other packages. This release builds on and extends the work of the recent 0.3.18 release and tweaks some of the test. We cannot fully test all platforms used by CRAN so some times iterations such as this one are needed. The package was uploaded a few days ago, but it sometimes takes a few days to clarify changes over email to the CRAN maintainers whose work is still greatly appreciated. The NEWS extract follows and details the changes some more.

Changes in inline version 0.3.19 (2021-05-25)
  • Documentation for moveDLL was updated and extended (Johannes in #22).
  • A few more tests were made conditional the test platform (Dirk in #24).

Courtesy of my CRANberries, there is a comparison to the previous release. If you like this or other open-source work I do, you can now sponsor me at GitHub.

Dirk Eddelbuettel: td 0.0.3 on CRAN: Maintenance release

The still recent-ish td package for accessing the twelvedata API for financial data has been updated on CRAN yesterday, and is now at released version 0.0.3. A few URLs were updated to please the lint checker, and a Depends: on R 4.0.0 or later was added. We then realized (as always just after the release ) that the core issue was an incorrect version comparison which we already fixed in the git repo. The NEWS entry follows.

Changes in version 0.0.3 (2021-05-29)
  • The package now (formally) depends on R (>= 4.0.0) as it uses a recently added R function for the default config file.
  • A few URLs were updated in the README.md file

Courtesy of my CRANberries, there is a comparison to the previous release. For questions or comments use the issue tracker off the GitHub repo. If you like this or other open-source work I do, you can now sponsor me at GitHub.

Russell Coker: HP ML110 Gen9

I ve just bought a HP ML110 Gen9 as a personal workstation, here are my notes about it and documentation on running Debian on it. Why a Server? I bought this is because the ML350p Gen8 turned out to be too noisy for my taste [1]. I ve just been editing my page about Memtest86+ RAM speeds [2], over the course of 10 years (high end laptop in 2001 to low end server in 2011) RAM speed increased by a factor of 100. RAM speed has been increasing at a lower rate than CPU speed and is becoming an increasing bottleneck on system performance. So while I could get a faster white-box system the cost of a second-hand server isn t that great and I m getting a system that s 100* faster than what was adequate for most tasks in 2001. HP makes some nice workstation class machines with ECC RAM (think server without remote management, hot-swap disks, or redundant PSU but with sound hardware). But they are significantly more expensive on the second hand market than servers. This server cost me $650 and came with 2*480G DC grade SSDs (Intel but with HPE stickers). I hope that more than half of the purchase price will be recovered from selling the SSDs (I will use NVMe). Also 64G of non-ECC RAM costs $370 from my local store. As I want lots of RAM for testing software on VMs it will probably turn out that the server cost me less than the cost of new RAM once I ve sold the SSDs! Monitoring 
wget -O /usr/local/hpePublicKey2048_key1.pub https://downloads.linux.hpe.com/SDR/hpePublicKey2048_key1.pub
echo "# HP monitoring" >> /etc/apt/sources.list
echo "deb [signed-by=/usr/local/hpePublicKey2048_key1.pub] http://downloads.linux.hpe.com/SDR/downloads/MCP/Debian/ stretch/current-gen9 non-free" >> /etc/apt/sources.list
The above commands will make the management utilities installable on Debian/Buster. If using Bullseye (Testing at the moment) then you need to have Buster repositories in APT for dependencies, HP doesn t seem to have packaged all their utilities for Buster. 
wget -r -np -A Contents-amd64.bz2 http://downloads.linux.hpe.com/SDR/repo/mcp/debian/dists
To find out which repositories had the programs I need I ran the above recursive wget and then uncompressed them for grep -R (as an aside it would be nice if bzgrep supported -R). I installed the hp-health package which has hpasmcli for viewing and setting many configuration options and hplog for viewing event log data and thermal data (among a few other things). I ve added a new monitor to etbemon hp-temp.monitor to monitor HP server temperatures, I haven t made a configuration option to change the thresholds for what is considered normal because I don t expect server class systems to be routinely running above the warning temperature. For the linux-temp.monitor script I added a command-line option for the percentage of the high temperature that is an error condition as well as an option for the number of CPU cores that need to be over-temperature, having one core permanently over the high temperature due to a web browser seems standard for white-box workstations nowadays. The hp-health package depends on libc6-i686 lib32gcc1 even though none of the programs it contains use lib32gcc1. Depending on lib32gcc1 instead of lib32gcc1 lib32gcc-s1 means that installing hp-health requires removing mesa-opencl-icd which probably means that BOINC can t use the GPU among other things. I solved this by editing /var/lib/dpkg/status and changing the package dependencies to what I desired. Note that this is not something for a novice to do, make a backup and make sure you know what you are doing! Issues The HPE Dynamic Smart Array B140i is a software RAID device. While it s convenient for some users that software RAID gets supported in the UEFI boot process, generally software RAID is a bad idea. Also my system has hot-swap drive caddies but the controller doesn t support hot-swap. So the first thing to do was to configure the array controller to run in AHCI mode and give up on using hot-swap drive caddies for hot-swap. I tested all the documented ways of scanning for new devices and nothing other than a reboot made the kernel recognise a new SATA disk. According to specs provided by Dell and HP the ML110 Gen9 makes less noise than the PowerEdge T320, according to my own observations the reverse is the case. I don t know if this is because of Dell being more conservative in their specs than HP or because of how dBA is measured vs my own personal annoyance thresholds for sounds. As the system makes more noise than I m comfortable with I plan to build a rubber enclosure for the rear of the system to reduce noise, that will be the subject of another post. For Australian readers Bunnings has some good deals on rubber floor mats that can be used to reduce server noise. The server doesn t have sound hardware, while one could argue that servers don t need sound there are some server uses for sound hardware such as using line input as a source of entropy. Also for a manufacturer it might be a benefit to use the same motherboard for workstations and servers. Fortunately a friend gave me a nice set of Logitech USB speakers a few years ago that I hadn t previously had a cause to use, so that will solve the problem for me (I don t need line-in on a workstation). UEFI and Memtest I decided to try UEFI boot for something new (in the past I d only used UEFI boot for a server that only had large disks). In the past I ve booted all my own systems with BIOS boot because I m familiar with it and they all have SSDs for booting which are less than 2TB in size (until recently 2TB SSDs weren t affordable for my personal use). The Debian UEFI wiki page is worth reading [3]. The Debian Wiki page about ProLiant servers [4] is worth reading too. Memtest86+ doesn t support EFI booting (just goes to a black screen) even though Debian/Buster puts in a GRUB entry for it (Debian bug #695246 was filed for this in 2012). Also on my ML110 Memtest86+ doesn t report the RAM speed (a known issue on Memtest86+). Comments on the net say that Memtest86+ hasn t been maintained for a long time and Memtest86 (the non-free version) has been updated more recently. So far I haven t seen a system with ECC RAM have a memory problem that could be detected by Memtest86+, the memory problems I ve seen on ECC systems have been things that prevent booting (RAM not being recognised correctly), that are detected by the BIOS as ECC errors before booting, or that are reported by the kernel as ECC errors at run time (happened years ago and I can t remember the details). Overall I m not a fan of EFI with the way it currently works in Debian. It seems to add some of the GRUB functionality into the BIOS and then use that to load GRUB. It seems that EFI can do everything you need and it would be better to just have a single boot loader not two of them chained. Power Supply There are a range of PSUs for the ML110, the one I have has the smallest available PSU (350W) and doesn t have a PCIe power cable (the one used for video cards). Here is the HP document which shows the cabling for the various ML110 Gen8 PSUs [5], I have the 350W PSU. One thing I ve considered is whether I could make an adaptor from the drive bay power to the PCIe connector. A quick web search indicates that 4 SAS disks when active can take up to 75W more power than a system with no disks. If that s the case then the 2 spare drive bay connectors which can each handle 4 disks should be able to supply 150W. As a 6 pin PCIe power cable (GPU power cable) is rated at 75W that should be fine in theory (here s a page with the pinouts for PCIe power connectors [6]). My video card is a Radeon R7 260X which apparently takes about 113W all up so should be taking less than 75W from the PCIe power cable. All I really want is YouTube, Netflix, and text editing at 4K resolution. So I don t need much in terms of 3D power. KDE uses some of the advanced features of modern video cards, but it doesn t compare to 3D gaming. According to the Wikipedia page for Radeon RX 500 series [7] the RX560 supports DisplayPort 1.4 and HDMI 2.0 (both of which do 4K@60Hz) and has a TDP of 75W. So a RX560 video card seems like a good option that will work in any system that doesn t have a spare PCIe power cable. I ve just ordered one of those for $246 so hopefully that will arrive in a week or so. PCI Fan The ML110 Gen9 has an optional PCIe fan and baffle to cool PCIe cards (part number 784580-B21). Extra cooling of PCIe cards is a good thing, but $400 list price (and about $50 ebay price) for the fan and baffle is unpleasant. When I boot the system with a PCIe dual-ethernet card and two PCIe NVMe cards it gives a BIOS warning on boot, when I add a video card it refuses to boot without the extra fan. It s nice that the system makes sure it doesn t get into a thermal overload situation, but it would be nicer if they just shipped all necessary fans with it instead of trying to get more money out of customers. I just bought a PCI fan and baffle kit for $60. Conclusion In spite of the unexpected expense of a new video card and PCI fan the overall cost of this system is still low, particularly when considering that I ll find another use for the video card which needs and extra power connector. It is disappointing that HP didn t supply a more capable PSU and fit all the fans to all models, the expectation of a server is that you can just do server stuff not have to buy extra bits before you can do server stuff. If you want to install Tesla GPUs or something then it s expected that you might need to do something unusual with a server, but the basic stuff should just work. A single processor tower server should be designed to function as a deskside workstation and be able to handle an average video card. Generally it s a nice computer, I look forward to getting the next deliveries of parts so I can make it work properly.

Russ Allbery: Review: The Silver Chair

Review: The Silver Chair, by C.S. Lewis
Illustrator: Pauline Baynes
Series: Chronicles of Narnia #4
Publisher: Collier
Copyright: 1953
Printing: 1978
ISBN: 0-02-044250-5
Format: Mass market
Pages: 217
The Silver Chair is a sequel to The Voyage of the Dawn Treader and the fourth book of the Chronicles of Narnia in original publication order. (For more about publication order, see the introduction to my review of The Lion, the Witch and the Wardrobe.) Apart from a few references to The Voyage of the Dawn Treader at the start, it stands sufficiently on its own that you could read it without reading the other books, although I have no idea why you'd want to. We have finally arrived at my least favorite of the Narnia books and the one that I sometimes skipped during re-reads. (One of my objections to the new publication order is that it puts The Silver Chair and The Last Battle back-to-back, and I don't think you should do that to yourself as a reader.) I was hoping that there would be previously unnoticed depth to this book that would redeem it as an adult reader. Sadly, no; with one very notable exception, it's just not very good. MAJOR SPOILERS BELOW. The Silver Chair opens on the grounds of the awful school to which Eustace's parents sent him: Experiment House. That means it opens (and closes) with a more extended version of Lewis's rant about schools. I won't get into this in detail since it's mostly a framing device, but Lewis is remarkably vicious and petty. His snide contempt for putting girls and boys in the same school did not age well, nor did his emphasis at the end of the book that the incompetent head of the school is a woman. I also raised an eyebrow at holding up ordinary British schools as a model of preventing bullying. Thankfully, as Lewis says at the start, this is not a school story. This is prelude to Jill meeting Eustace and the two of them escaping the bullies via a magical door into Narnia. Unfortunately, that's the second place The Silver Chair gets off on the wrong foot. Jill and Eustace end up in what the reader of the series will recognize as Aslan's country and almost walk off the vast cliff at the end of the world, last seen from the bottom in The Voyage of the Dawn Treader. Eustace freaks out, Jill (who has a much better head for heights) goes intentionally close to the cliff in a momentary impulse of arrogance before realizing how high it is, Eustace tries to pull her back, and somehow Eustace falls over the edge. I do not have a good head for heights, and I wonder how much of it is due to this memorable scene. I certainly blame Lewis for my belief that pulling someone else back from the edge of a cliff can result in you being pushed off, something that on adult reflection makes very little sense but which is seared into my lizard brain. But worse, this sets the tone for the rest of the story: everything is constantly going wrong because Eustace and Jill either have normal human failings that are disproportionately punished or don't successfully follow esoteric and unreasonably opaque instructions from Aslan. Eustace is safe, of course; Aslan blows him to Narnia and then gives Jill instructions before sending her afterwards. (I suspect the whole business with the cliff was an authorial cheat to set up Jill's interaction with Aslan without Eustace there to explain anything.) She and Eustace have been summoned to Narnia to find the lost Prince, and she has to memorize four Signs that will lead her on the right path. Gah, the Signs. If you were the sort of kid that I was, you immediately went back and re-read the Signs several times to memorize them like Jill was told to. The rest of this book was then an exercise in anxious frustration. First, Eustace is an ass to Jill and refuses to even listen to the first Sign. They kind of follow the second but only with heavy foreshadowing that Jill isn't memorizing the Signs every day like she's supposed to. They mostly botch the third and have to backtrack to follow it. Meanwhile, the narrator is constantly reminding you that the kids (and Jill in particular) are screwing up their instructions. On re-reading, it's clear they're not doing that poorly given how obscure the Signs are, but the ominous foreshadowing is enough to leave a reader a nervous wreck. Worse, Eustace and Jill are just miserable to each other through the whole book. They constantly bicker and snipe, Eustace doesn't want to listen to her and blames her for everything, and the hard traveling makes it all worse. Lewis does know how to tell a satisfying redemption arc; one of the things I have always liked about Edmund's story is that he learns his lesson and becomes my favorite character in the subsequent stories. But, sadly, Eustace's redemption arc is another matter. He's totally different here than he was at the start of The Voyage of the Dawn Treader (to the degree that if he didn't have the same name in both books, I wouldn't recognize him as the same person), but rather than a better person he seems to have become a different sort of ass. There's no sign here of the humility and appreciation for friendship that he supposedly learned from his time as a dragon. On top of that, the story isn't very interesting. Rilian, the lost Prince, is a damp squib who talks in the irritating archaic accent that Lewis insists on using for all Narnian royalty. His story feels like Lewis lifted it from medieval Arthurian literature; most of it could be dropped into a collection of stories of knights of the Round Table without seeming out of place. When you have a country full of talking animals and weirdly fascinating bits of theology, it's disappointing to get a garden-variety story about an evil enchantress in which everyone is noble and tragic and extremely stupid. Thankfully, The Silver Chair has one important redeeming quality: Puddleglum. Puddleglum is a Marsh-wiggle, a bipedal amphibious sort who lives alone in the northern marshes. He's recruited by the owls to help the kids with their mission when they fail to get King Caspian's help after blowing the first Sign. Puddleglum is an absolute delight: endlessly pessimistic, certain the worst possible thing will happen at any moment, but also weirdly cheerful about it. I love Eeyore characters in general, but Puddleglum is even better because he gives the kids' endless bickering exactly the respect that it deserves.
"But we all need to be very careful about our tempers, seeing all the hard times we shall have to go through together. Won't do to quarrel, you know. At any rate, don't begin it too soon. I know these expeditions usually end that way; knifing one another, I shouldn't wonder, before all's done. But the longer we can keep off it "
It's even more obvious on re-reading that Puddleglum is the only effective member of the party. Jill has only a couple of moments where she gets the three of them past some obstacle. Eustace is completely useless; I can't remember a single helpful thing he does in the entire book. Puddleglum and his pessimistic determination, on the other hand, is right about nearly everything at each step. And he's the one who takes decisive action to break the Lady of the Green Kirtle's spell near the end. I was expecting a bit of sexism and (mostly in upcoming books) racism when re-reading these books as an adult given when they were written and who Lewis was, but what has caught me by surprise is the colonialism. Lewis is weirdly insistent on importing humans from England to fill all the important roles in stories, even stories that are entirely about Narnians. I know this is the inherent weakness of portal fantasy, but it bothers me how little Lewis believes in Narnians solving their own problems. The Silver Chair makes this blatantly obvious: if Aslan had just told Puddleglum the same information he told Jill and sent a Badger or a Beaver or a Mouse along with him, all the evidence in the book says the whole affair would have been sorted out with much less fuss and anxiety. Jill and Eustace are far more of a hindrance than a help, which makes for frustrating reading when they're supposedly the protagonists. The best part of this book is the underground bits, once they finally get through the first three Signs and stumble into the Lady's kingdom far below the surface. Rilian is a great disappointment, but the fight against the Lady's mind-altering magic leads to one of the great quotes of the series, on par with Reepicheep's speech in The Voyage of the Dawn Treader.
"Suppose we have only dreamed, or made up, all those things trees and grass and sun and moon and stars and Aslan himself. Suppose we have. Then all I can say is that, in that case, the made-up things seem a good deal more important than the real ones. Suppose this black pit of a kingdom of yours is the only world. Well, it strikes me as a pretty poor one. And that's a funny thing, when you come to think of it. We're just babies making up a game, if you're right. But four babies playing a game can make a play-world which licks your real world hollow. That's why I'm going to stand by the play world. I'm on Aslan's side even if there isn't any Aslan to lead it. I'm going to live as like a Narnian as I can even if there isn't any Narnia. So, thanking you kindly for our supper, if these two gentlemen and the young lady are ready, we're leaving your court at once and setting out in the dark to spend our lives looking for Overland. Not that our lives will be very long, I should think; but that's small loss if the world's as dull a place as you say."
This is Puddleglum, of course. And yes, I know that this is apologetics and Lewis is talking about Christianity and making the case for faith without proof, but put that aside for the moment, because this is still powerful life philosophy. It's a cynic's litany against cynicism. It's a pessimist's defense of hope. Suppose we have only dreamed all those things like justice and fairness and equality, community and consensus and collaboration, universal basic income and effective environmentalism. The dreary magic of the realists and the pragmatists say that such things are baby's games, silly fantasies. But you can still choose to live like you believe in them. In Alasdair Gray's reworking of a line from Dennis Lee, "work as if you live in the early days of a better nation." That's one moment that I'll always remember from this book. The other is after they kill the Lady of the Green Kirtle and her magic starts to fade, they have to escape from the underground caverns while surrounded by the Earthmen who served her and who they believe are hostile. It's a tense moment that turns into a delightful celebration when they realize that the Earthmen were just as much prisoners as the Prince was. They were forced from a far deeper land below, full of living metals and salamanders who speak from rivers of fire. It's the one moment in this book that I thought captured the magical strangeness of Narnia, that sense that there are wonderful things just out of sight that don't follow the normal patterns of medieval-ish fantasy. Other than a few great lines from Puddleglum and some moments in Aslan's country, the first 60% of this book is a loss and remarkably frustrating to read. The last 40% isn't bad, although I wish Rilian had any discernible character other than generic Arthurian knight. I don't know what Eustace is doing in this book at all other than providing a way for Jill to get into Narnia, and I wish Lewis had realized Puddleglum could be the protagonist. But as frustrating as The Silver Chair can be, I am still glad I re-read it. Puddleglum is one of the truly memorable characters of children's literature, and it's a shame he's buried in a weak mid-series book. Followed, in the original publication order, by The Horse and His Boy. Rating: 6 out of 10

Shirish Agarwal: Planes, Pandemic and Medical Devices I

The Great Electric Airplane Race It took me quite sometime to write as have been depressed about things. Then a few days back saw Nova s The Great Electric Airplane Race. While it was fabulous and a pleasure to see and know that there are more than 200 odd startups who are in the race of making an electric airplane which works and has FAA certification. I was disappointed though that there no coverage of any University projects. From what little I know, almost all advanced materials which U.S. had made has been first researched in mostly Universities and when it is close to fruition then either spin-off as a startup or give to some commercial organization/venture to make it scalable and profitable. If they had, I am sure more people could be convinced to join sciences and engineering in college. I actually do want to come to this as part of both general medicine and vaccine development in U.S. but will come later. The idea that industry works alone should be discouraged, but that perhaps may require another article to articulate why I believe so.

Medical Device Ventilators in India Before the pandemic, probably most didn t know what a ventilator is and was, at least I didn t, although I probably used it during my somewhat brief hospital stay a couple of years ago. It entered into the Indian twitter lexicon more so in the second wave as the number of people who got infected became more and more and the ventilators which were serving them became less and less just due to sheer mismatch of numbers and requirements. Rich countries donated/gifted ventilators to India on which GOI put GST of 28%. Apparently, they are a luxury item, just like my hearing aid. Last week Delhi High Court passed a judgement that imposition of GST should not be on a gift like ventilators or oxygenators. The order can be found here. Even without reading the judgement the shout from the right was judicial activism while after reading it is a good judgement which touches on several points. The first, in itself, stating the dichotomy that if a commercial organization wanted to import a ventilator or an oxygenator the IGST payable is nil while for an individual it is 12%. The State (here State refers to State Government in this case Gujarat Govt.) did reduce the IGST for state from 12% to NIL IGST for federal states but that to till only 30.06.2021. No relief to individuals on that account. The Court also made use of Mr. Arvind Datar, as Amicus Curiae or friend of court. The petitioner, an 85-year-old gentleman who has put it up has put broad assertions under Article 21 (right to live) and the court in its wisdom also added Article 14 which enshrines equality of everyone before law. The Amicus Curiae, as his duty, guided the court into how the IGST law works and shared a brief history of the law and the changes happening before and after it. During his submissions, he also shared the Mega Exemption Notification no. 50/2017 under which several items are there which are exempted from putting IGST. The Amicus Curiae did note that such exemptions were also there before Mega Exemption Notification had come into play. However, DGFT (Directorate General of Foreign Trade) on 30-04-2021 issued notification No. 4/2015-2020 through which oxygenators had been exempted from Custom Duty/BCD (Basic Customs Duty. In another notification on no. 30/2021 dated 01.05.2021 it reduced IGST from 28% to 12% for personal use. If however the oxygenator was procured by a canalizing agency (bodies such as State Trading Corporation of India (STC) or/and Metals and Minerals Corporation (MMTC) and such are defined as canalising agents) then it will be fully exempted from paying any sort of IGST, albeit subject to certain conditions. What the conditions are were not shared in the open court. The Amicus Curiae further observed that it is contrary to practice where both BCD and IGST has been exempted for canalising agents and others, some IGST has to be paid for personal use. To share within the narrow boundaries of the topic, he shared entry no. 607A of General Exemption no.190 where duty and IGST in case of life-saving drugs are zero provided the life-saving drugs imported have been provided by zero cost from an overseas supplier for personal use. He further shared that the oxygen generator would fall in the same entry of 607A as it fulfills all the criteria as shared for life-saving medicines and devices. He also used the help of Drugs and Cosmetics Act 1940 which provides such a relief. The Amicus Curiae further noted that GOI amended its foreign trade policy (2015-2020) via notification no.4/2015-2020, dated 30.04.2021, issued by DGFT where Rakhi and life-saving drugs for personal use has been exempted from BCD till 30-07-2021. No reason not to give the same exemption to oxygenators which fulfill the same thing. The Amicus Curiae, further observes that there are exceptional circumstances provisions as adverted to in sub-section (2) of Section 25 of the Customs Act, whereby Covid-19 which is known and labelled as a pandemic where the distinctions between the two classes of individuals or agencies do not make any sense. While he did make the observation that exemption from duty is not a right, in the light of the pandemic and Article 14, it does not make sense to have distinctions between the two classes of importers. He further shared from Circular no. 9/2014-Customs, dated 19.08.2014 by CBEC (Central Board of Excise and Customs) which gave broad exemptions under Section 25 (2) of the same act in respect of goods and services imported for safety and rehabilitation of people suffering and effected by natural disasters and epidemics. He further submits that the impugned notification is irrational as there is no intelligible differentia rule applied or observed in classifying the import of oxygen concentrators into two categories. One, by the State and its agencies; and the other, by an individual for personal use by way of gift. So there was an absence of adequate determining principle . To bolster his argument, he shared the judgements of

a) Union of India vs. N.S. Rathnam & Sons, (2015) 10 SCC 681 (N.S. Ratnams and Sons Case) b) Shayara Bano vs. Union of India, (2017) 9 SCC 1 (Shayara Bano Case) The Amicus Curiae also rightly observed that the right to life also encompasses within it, the right to health. You cannot have one without the other and within that is the right to have affordable treatment. He further stated that the state does not only have a duty but a positive obligation is cast upon it to ensure that the citizen s health is secured. He again cited Navtej Singh Johars vs Union of India (Navtej Singh Johar Case) in defence of right to life. Mr. Datar also shared that unlike in normal circumstances, it is and should be enough to show distinct and noticeable burdensomeness which is directly attributable to the impugned/questionable tax. The gentleman cited Indian Express Newspapers (Bombay) Private Limited vs. Union of India, (1985) 1 SCC 641 (Indian Express case) 1985 which shared both about Article 19 (1) (a) and Article 21. Bloggers note At this juncture, I should point out which I am sharing the judgement and I would be sharing only the Amicus Curiae POV and then the judge s final observations. While I was reading it, I was stuck by the fact that the Amicus Curiae had cited 4 cases till now, 3 of them are pretty well known both in the legal fraternity and even among public at large. Another 3 which have been shared below which are also of great significance. Hence, felt the need to share the whole judgement. The Amicus Curiae further observed that this tax would have to be disproportionately will have to be paid by the old and the infirm, and they might find it difficult to pay the amounts needed to pay the customs duty/IGST as well as find the agent to pay in this pandemic. Blogger Note The situation with the elderly is something like this. Now there are a few things to note, only Central Govt. employees and pensioners get pensions which has been freezed since last year. The rest of the elderly population does not. The rate of interest has fallen to record lows from 5-6% in savings interest rate to 2% and on Fixed Deposits at 4.9% while the nominal inflation rate has up by 6% while CPI and real inflation rates are and would be much more. And this is when there is absolutely no demand in the economy. To add to all this, RBI shared a couple of months ago that fraud of 5 trillion rupees has been committed between 2015 and 2019 in banks. And this is different from the number of record NPA s that have been both in Public and Private Sector banks. To get out of this, the banks have squeezed their customers and are squeezing as well as asking GOI for bailouts. How much GOI is responsible for the frauds as well as NPA s would probably require its own space. And even now, RBI and banks have made heavy provisions as lockdowns are still a facet and are supposed to remain a facet till the end of the year or even next year (all depending upon when we get the vaccine). The Amicus Curiae further argued that the ventilators which are available locally are of bad quality. The result of all this has resulted in a huge amount of unsurmountable pressure on hospitals which they are unable to overcome. Therefore, the levy of IGST on oxygenators has direct impact on health of the citizen. So the examination of the law should not be by what intention it was but how it is affecting citizen rights now. For this he shared R.C.Cooper vs Union of India (another famous case R.C. Cooper vs Union of India) especially paragraph 49 and Federation of Hotel & Restaurant Association of India vs. Union of India, (1989) at paragraph 46 (Federation of Hotel Case) Mr. Datar further shared the Supreme Court order dated 18.12.2020, passed in Suo Moto Writ Petition(Civil) No.7/2020, to buttress the plea that the right to health includes the right to affordable treatment. Blogger s Note For those, who don t know Suo Moto is when the Court, whether Supreme Court or the High Courts take up a matter for public good. It could be in anything, law and order, Banking, Finance, Public Health etc. etc. This was the norm before 2014. The excesses of the executive were curtailed by both the Higher and the lower Judiciary. That is and was the reason that Judiciary is and was known as the third pillar of Indian democracy. A good characterization of Suo Moto can be found here. Before ending his submission, the learned Amicus Curiae also shared Jeeja Ghosh vs. Union of India, (2016) (Jeeja Ghosh Case, an outstanding case as it deals with people with disabilities and their rights and the observations made by the Division Bench of Hon ble Mr. Justice A. K. Sikri as well as Hon ble Mr. Justice R. K. Agrawal.) After Amicus Curiae completed his submissions, it was the turn of Mr. Sudhir Nandrajog, and he adopted the arguments and submissions made by the Amicus Curiae. The gentleman reiterated the facts of the case and how the impugned notification was violative of both Article 14 and 21 of the Indian Constitution. Blogger s Note The High Court s judgement which shows all the above arguments by the Amicus Curiae and the petitioner s lawyer also shared the State s view. It is only on page 24, where the Delhi High Court starts to share its own observations on the arguments of both sides. Judgement continued The first observation that the Court makes is that while the petitioner demonstrated that the impugned tax imposition would have a distinct and noticeable burdensomeness while the State did not state or share in any way how much of a loss it would incur if such a tax were let go and how much additional work would have to be done in order to receive this specific tax. It didn t need to do something which is down the wire or mathematically precise, but it didn t even care to show even theoretically how many people will be affected by the above. The counter-affidavit by the State is silent on the whole issue. The Court also contended that the State failed to prove how collecting IGST from the concerned individuals would help in fighting coronavirus in any substantial manner for the public at large. The High Court shared observations from the Navtej Singh Johar case where it is observed that the State has both negative and positive obligations to ensure that its citizens are able to enjoy the right to health. The High Court further made the point that no respectable person does like to be turned into a charity case. If the State contends that those who obey the law should pay the taxes then it is also obligatory on the state s part to lessen exactions such as taxes at the very least in times of war, famine, floods, epidemics and pandemics. Such an approach would lead a person to live a life of dignity which is part of Article 21 of the Constitution. Another point that was made by the State that only the GST council is able to make any changes as regards to exemptions rather than the State were found to be false as the State had made some exemptions without going to the GST council using its own powers under Section 25 of the Customs Act. The Court also points out that it does send a discriminatory pattern when somebody like petitioner has to pay the tax for personal use while those who are buying it for commercial use do not have to pay the tax. The Court agreed of the view of the Amicus Curiae, Mr. Datar that oxygenator should be taxed at NIL rate at IGST as it is part of life-saving drugs and oxygenator fits the bill as medical equipment as it is used in the treatment, mitigation and prevention of spread of Coronavirus. Mr. Datar also did show that oxygenator is placed at the same level as other life-saving drugs. The Court felt further emboldened as the observations by Supreme Court in State of Andhra Pradesh vs. Linde India Limited, 2020 ( State of Andhra Pradesh vs Linde Ltd.) The Court further shared many subsequent notifications from the State and various press releases by the State itself which does make the Court s point that oxygenators indeed are drugs as defined in the court case above. The State should have it as part of notification 190. This would preserve the start of the notification date from 03.05.2021 and the state would not have to issue a new notification. The Court further went to postulate that any persons similar to the petitioner could avail of the same, if they furnish a letter of undertaking to an officer designated by the State that the medical equipment would not be put to commercial use. Till the state does not do that, in the interim the importer could give the same undertaking to Joint Secretary, Customs or their nominee can hand over the same to custom officer. The Court also shared that it does not disagree with the State s arguments but the challenges which have arisen are in a unique time period/circumstances, so they are basing their judgement based on how the situation is. The Court also mentioned an order given by Supreme Court Diary No. 10669/2020 passed on 20.03.2020 where SC has taken pains to understand the issues faced by the citizens. The court also mentioned the Small Scale Industrial Manufactures Association Case (both of these cases I don t know) . So in conclusion, the Court holds the imposition of IGST on oxygenator which are imported by individuals as gifts from their relatives as unconstitutional. They also shared that any taxes taken by GOI in above scenario have to be returned. The relief to the state is they will not have to pay interest cost on the same. To check misuse of the same, the petitioner or people who are in similar circumstances would have to give a letter of undertaking to an officer designated by the State within 7 days of the state notifying the patient or anybody authorized by him/her to act on their behalf to share the letter of undertaking with the State. And till the State doesn t provide an officer, the above will continue. Hence, both the writ petition and the pending application are disposed off. The Registry is directed to release any money deposited by the petitioner along with any interest occurred on it (if any) . At the end they record appreciation of Mr. Arvind Datar, Mr. Zoheb Hossain, Mr. Sudhir Nandrajog as well as Mr. Siddharth Bambha. It is only due to their assistance that the court could reach the conclusion it did. For Delhi High Court RAJIV SHAKDHER, J. TALWANT SINGH, J. May 21, 2020 Blogger s Observations Now, after the verdict GOI does have few choices, either accept the verdict or appeal in the SC. A third choice is to make a committee and come to the same conclusions via the committee. GOI has done something similar in the past. If that happens and the same conclusions are reached as before, then the aggrieved may have no choice but to appear in the highest court of law. And this will put the aggrieved at a much more vulnerable place than before as SC court fees, lawyer fees etc. are quite high compared to High Courts. So, there is a possibility that the petitioner may not even approach unless and until some non-profit (NGO) does decide to fight and put it up as common cause or something similar. There is another judgement that I will share, probably tomorrow. Thankfully, that one is pretty short compared to this one. So it should be far more easier to read. FWIW, I did learn about the whole freeenode stuff and many channels who have shifted from freenode to libera. I will share my own experience of the same but that probably will take a day or two.
Zeeshan of IYC (India Youth Congress) along with Salman Khan s non-profit Being Human getting oxygenators
The above picture of Zeeshan. There have been a whole team of Indian Youth Congress workers (main opposition party to the ruling party) who have doing lot of relief effort. They have been buying Oxygenators from abroad with help of Being Human Foundation started by Salman Khan, an actor who works in A-grade movies in Bollywood.

Wouter Verhelst: SReview and pandemics

The pandemic was a bit of a mess for most FLOSS conferences. The two conferences that I help organize -- FOSDEM and DebConf -- are no exception. In both conferences, I do essentially the same work: as a member of both video teams, I manage the postprocessing of the video recordings of all the talks that happened at the respective conference(s). I do this by way of SReview, the online video review and transcode system that I wrote, which essentially crowdsources the manual work that needs to be done, and automates as much as possible of the workflow. The original version of SReview consisted of a database, a (very basic) Mojolicious-based webinterface, and a bunch of perl scripts which would build and execute ffmpeg command lines using string interpolation. As a quick hack that I needed to get working while writing it in my spare time in half a year, that approach was workable and resulted in successful postprocessing after FOSDEM 2017, and a significant improvement in time from the previous years. However, I did not end development with that, and since then I've replaced the string interpolation by an object oriented API for generating ffmpeg command lines, as well as modularized the webinterface. Additionally, I've had help reworking the user interface into a system that is somewhat easier to use than my original interface, and have slowly but surely added more features to the system so as to make it more flexible, as well as support more types of environments for the system to run in. One of the major issues that still remains with SReview is that the administrator's interface is pretty terrible. I had been planning on revamping that for 2020, but then massive amounts of people got sick, travel was banned, and both the conferences that I work on were converted to an online-only conference. These have some very specific requirements; e.g., both conferences allowed people to upload a prerecorded version of their talk, rather than doing the talk live; since preprocessing a video is, technically, very similar to postprocessing it, I adapted SReview to allow people to upload a video file that it would then validate (in terms of length, codec, and apparent resolution). This seems like easy to do, but I decided to implement this functionality so that it would also allow future use for in-person conferences, where occasionally a speaker requests that modifications would be made to the video file in a way that SReview is unable to do. This made it marginally more involved, but at least will mean that a feature which I had planned to implement some years down the line is now already implemented. The new feature works quite well, and I'm happy I've implemented it in the way that I have. In order for the "upload" processing and the "post-event" processing to not be confused, however, I decided to import the conference schedules twice: once as the conference itself, and once as a shadow version of that conference for the prerecordings. That way, I could track the progress through the system of the prerecording completely separately from the progress of the postprocessing of the video (which adds opening/closing credits, and transcodes to multiple variants of the same video). Schedule parsing was something that had not been implemented in a generic way yet, however; since that made doubling the schedule in that way rather complex, I decided to bite the bullet and (finally) implement schedule parsing in a generic way. Currently, schedule parsers exist for two formats (Pentabarf XML and the Wafer variant of that same format which is almost, but not quite, entirely the same). The API for that is quite flexible, and I'm happy with the way things have been implemented there. I've also implemented a set of "virtual" parsers, which allow mangling the schedule in various ways (by either filtering out talks that we don't want, or by generating the shadow version of the schedule that I talked about earlier). While the SReview settings have reasonable defaults, occasionally the output of SReview is not entirely acceptable, due to more complicated matters that then result in encoding artifacts. As a result, the DebConf video team has been doing a final review step, completely outside of SReview, to ensure that such encoding artifacts don't exist. That seemed suboptimal, so recently I've been working on integrating that into SReview as well. First tests have been run, and seem to be acceptable, but there's still a few loose ends to be finalized. As part of this, I've also reworked the way comments could be entered into the system. Previously the presence of a comment would signal that the video has some problems that an administrator needed to look at. Unfortunately, that was causing some confusion, with some people even thinking it's a good place to enter a "thank you for your work" style of comment... which it obviously isn't. Turning it into a "comment log" system instead fixes that, and also allows for better two-way communication between administrators and reviewers. Hopefully that'll improve things in that area as well. Finally, the audio normalization in SReview -- for which I've long used bs1770gain -- is having problems. First of all, bs1770gain will sometimes alter the timing of the video or audio file that it's passed, which is very problematic if I want to process it further. There is an ffmpeg loudnorm filter which implements the same algorithm, so that should make things easier to use. Secondly, the author of bs1770gain is a strange character that I'd rather not be involved with. Before I knew about the loudnorm filter I didn't really have a choice, but now I can just rip bs1770gain out and replace it by the loudnorm filter. That will fix various other bugs in SReview, too, because SReview relies on behaviour that isn't actually there (but which I didn't know at the time when I wrote it). All in all, the past year-and-a-bit has seen a lot of development for SReview, with multiple features being added and a number of long-standing problems being fixed. Now if only the pandemic would subside, allowing the whole "let's do everything online only" wave to cool down a bit, so that I can finally make time to implement the admin interface...

Ian Jackson: Disconnecting from Freenode

I have just disconnected from irc.freenode.net for the last time. You should do the same. The awful new de facto operators are using user numbers as a public justification for their behaviour. Specifically, I recommend that you: Note that mentioning libera in the channel topic of your old channels on freenode is likely to get your channel forcibly taken over by the new de facto operators of freenode. They won't tolerate you officially directing people to the competition. I did an investigation and writeup of this situation for the Xen Project. It's a little out of date - it doesn't have the latest horrible behaviours from the new regime - but I think it is worth pasting it here: 
Message-ID: <24741.12566.639691.461134@mariner.uk.xensource.com>
From: Ian Jackson <iwj@xenproject.org>
To: xen-devel@lists.xenproject.org
CC: community.manager@xenproject.org
Subject: IRC networks
Date: Wed, 19 May 2021 16:39:02 +0100
Summary:
We have for many years used the Freenode IRC network for real-time
chat about Xen.  Unfortunately, Freenode is undergoing a crisis.
There is a dispute between, on the one hand, Andrew Lee, and on the
other hand, all (or almost all) Freenode volunteer staff.  We must
make a decision.
I have read all the publicly available materials and asked around with
my contacts.  My conclusions:
 * We do not want to continue to use irc.freenode.*.
 * We might want to use libera.chat, but:
 * Our best option is probably to move to OFTC https://www.oftc.net/
Discussion:
Firstly, my starting point.
I have been on IRC since at least 1993.  Currently my main public
networks are OFTC and Freenode.
I do not have any personal involvement with public IRC networks.  Of
the principals in the current Freenode dispute, I have only heard of
one, who is a person I have experience of in a Debian context but have
not worked closely with.
George asked me informally to use my knowledge and contacts to shed
light on the situation.  I decided that, having done my research, I
would report more formally and publicly here rather than just
informally to George.
Historical background:
 * Freenode has had drama before.  In about 2001 OFTC split off from
   Freenode after an argument over governance.  IIRC there was drama
   again in 2006.  Significant proportion of the Free Software world,
   including Debian, now use OFTC.  Debian switched in 2006.
Facts that I'm (now) pretty sure of:
 * Freenode's actual servers run on donated services; that is,
   the hardware is owned by those donating the services, and the
   systems are managed by Freenode volunteers, known as "staff".
 * The freenode domain names are currently registered to a limited
   liability company owned by Andrew Lee (rasengan).
 * At least 10 Freenode staff have quit in protest, writing similar
   resignation letters protesting about Andrew Lee's actions [1].  It
   does not appear that any Andrew Lee has the public support of any
   Freenode staff.
 * Andrew Lee claims that he "owns" Freenode.[2]
 * A large number of channel owners for particular Free Software
   projects who previously used Freenode have said they will switch
   away from Freenode.
Discussion and findings on Freenode:
There is, as might be expected, some murk about who said what to whom
when, what promises were made and/or broken, and so on.  The matter
was also complicated by the leaking earlier this week of draft(s) of
(at least one of) the Freenode staffers' resignation letters.
Andrew Lee has put forward a position statement [2].  A large part of
the thrust of that statement is allegations that the current head of
Freenode staff, tomaw, "forced out" the previous head, christel.  This
allegation is strongly disputed by by all those current (resigning)
Freenode staff I have seen comment.  In any case it does not seem to
be particularly germane; in none of my reading did tomaw seem to be
playing any kind of leading role.  tomaw is not mentioned in the
resignation letters.
Some of the links led to me to logs of discussions on #freenode.  I
read some of these in particular[3].  MB I haven't been able to verify
that these logs have not been tampered with.  Having said that and
taking the logs at face value, I found the rasengan writing there to
be disingenuous and obtuse.
Andrew Lee has been heavily involved in Bitcoin.  Bitcoin is a hive of
scum and villainy, a pyramid scheme, and an environmental disaster,
all rolled into one.  This does not make me think well of Lee.
Additionally, it seems that Andrew Lee has been involved in previous
governance drama involving a different IRC network, Snoonet.
I have come to the very firm conclusion that we should have nothing to
do with Andrew Lee, and avoid using services that he has some
effective control over.
Alternatives:
The departing Freenode staff are setting up a replacement,
"libera.chat".  This is operational but still suffering from teething
problems and of course has a significant load as it deals with an
influx of users on a new setup.
On the staff and trust question: As I say, I haven't heard of any of
the Freenode staff, with one exception.  Unfortunately the one
exception does not inspire confidence in me[4] - although NB that is
only one data point.
On the other hand, Debian has had many many years of drama-free
involvement with OFTC.  OFTC has a formal governance arrangement and
it is associated with Software in the Public Interest.  I notice that
the last few OFTC'[s annual officer elections have been run partly by
Steve McIntyre.  Steve is a friend of mine (and he is a former Debian
Project Leader) and I take his involvement as a good sign.
I recommend that we switch to using OFTC as soon as possible.
Ian.

Shirish Agarwal: Pandemic, Toolkit and India

Pandemic Situation in India. I don t know from where I should start. This is probably a good start. I actually would recommend Indiacable as they do attempt to share some things happening in India from day to day but still there is a lot thatt they just can t cover, nobody can cover. There were two reports which kind of shook me all inside. One which sadly came from the UK publication Independent, probably as no Indian publication would dare publish it. The other from Rural India. I have been privileged in many ways, including friends who have asked me if I need any financial help. But seeing reports like above, these people need more help, guidance and help than I. While I m never one to say give to Foundations. If some people do want to help people from Maharashtra, then moneylifefoundation could be a good place where they could donate. FWIW, they usually use the foundation to help savers and investors be safe and help in getting money when taken by companies with dubious intentions. That is their drive. Two articles show their bent. The first one is about the Algo scam which I have written previously about the same in this blog. Interestingly, when I talk about this scam, all Modi supporters are silent. The other one does give some idea as to why the Govt. is indifferent. That is going to a heavy cross for all relatives to bear. There has been a lot that has been happening. Now instead of being limited to cities, Covid has now gone hinterland in a big way. One could ask also Praveen as he probably knows what would be good for Kerala and surrounding areas. The biggest change, however, has been that India is now battling not just the pandemic but also Mucormycosis also known as black fungus and its deadlier cousin the white fungus. Mucormycosis came largely due to an ill-advise given that applying cow dung gives protection to Corona. And many applied it due to faith. And people who know science do know that in fact it has that bacteria. Sadly, those of us who are and were more interested in law, computer science etc. has now also have to keep on top of what is happening in the medical field. It isn t that I hate it, but it has a lot of costs. From what I could gather on various social media and elsewhere, a single injection of anti-fungal for the above costs INR 3k/- and that needs to be 5 times in a day and that course has to be for three weeks. So even the relatively wealthy people can and will become poor in no time. No wonder thousands of those went to UK, US, Dubai or wherever they could find safe-harbor from the pandemic with no plans of arriving back soon. There was also the whole bit about FBS or Fetal Bovin Serum. India ordered millions of blood serum products from abroad and continues to. This was quickly shut down as news on Social Media. Apparently, it is only the Indian cow which is worthy of reverence. All other cows and their children are fair game according to those in power. Of course, that discussion was quickly shut down as was the discussion about IGP (Indian Genome Project). People over the years had asked me why India never participated for the HGP (Human Gnome Project). I actually had no answer for that. Then in 2020, there was idea of IGP which was put up and then it was quickly shot down as the results could damage a political party s image. In fact, a note to people who want to join Indian civil services tells the reason exactly. While many countries in the world are hypocrites, including the U.S. none can take the place that India has made for itself in that field.

The Online experience The vaccination process has been made online and has led to severe heartburn and trouble for many including many memes. For e.g.

Daily work, get up, have a bath, see if you got a slot on the app, sleep.
People trying desperately to get a slot, taken from Hindi Movie Dilwale Dulhania Le Jaygenge.
Just to explain what is happening, one has to go to the website of cowin. Sharing a screenshot of the same.
Cowin app. sceeenshot
I have deliberately taken a screenshot of the cowin app. in U.P. which is one of the areas where the ruling party, BJP has. I haven t taken my state for the simple reason, even if a slot is open, it is of no use as there are no vaccines. As have been shared in India Cable as well as in many newspapers, it is the Central Govt. which holds the strings for the vaccines. Maharashtra did put up an international tender but to no effect. All vaccine manufacturers want only Central Govt. for purchases for multiple reasons. And GOI is saying it has no money even though recently it got loans as well as a dividend from RBI to the tune of 99k crore. For what all that money is, we have no clue. Coming back though, to the issue at hand. the cowin app. is made an open api. While normally, people like us should and are happy when an API is open, it has made those who understand how to use git, compile, etc. better than others. A copy of the public repo. of how you can do the same can be found on Github. Now, obviously, for people like me and many others it has ethical issues.

Kiran s Interview in Times of India (TOI) There isn t much to say apart from I haven t used it. I just didn t want to. It just is unethical. Hopefully, in the coming days GOI does something better. That is the only thing we are surviving on, hope.

The Toolkit saga A few days before, GOI shared a toolkit apparently made by Congress to defame the party in power. That toolkit was shared before the press and Altnews did the investigation and promptly shredded the claims. Congress promptly made an FIR in Chhattisgarh where it is in power. The gentleman who made the claims Mr. Sambit Patra refused to appear against the police without evidence citing personal reasons and asking 1 week to appear before them. Apart from Altnews which did a great job, sadly many people didn t even know that there is something called WYSIWYG. I had to explain that so many Industries, whether it is politics, creative industries, legal, ad industries, medical transcription, and imaging all use this, and all the participants use the same version of the software. The reason being that in most Industries, there is a huge loss and issue of legal liabilities if something untoward happens. For e.g. if medical transcription is done in India is wrong (although his or her work will be checked by a superior in the West), but for whatever reason is not, and a wrong diagnosis is put (due to wrong color or something) then a patient could die and the firm who does that work could face heavy penalties which could be the death of them. There is another myth that Congress has unlimited wealth or huge wealth. I asked if that was the case, why didn t they shift to Mac. Of course, none have answers on this one. There is another reason why they didn t want to appear. The Rona Wilson investigation by Arsenal Experts also has made them cautious. Previously, they had a free run. Nowadays, software forensic tools are available to one and all. For e.g. Debian itself has a good variety of tools for the same. I remember Vipin s sharing few years back. For those who want to start, just install the apps. and try figuring out. Expertise on using the tools takes years though, as you use the tool day in night. Update 25/05/2021 Apparently because Twitter made and showcased few tweets as Manipulated Media , those in Govt. are and were dead against it. So they conducted a raid against Twitter India headquarters, knowing fully well that there would be nobody except security. The moment I read this, my mind went to the whole Fruit of the poisonous tree legal doctrine. Sadly though, India doesn t recognize it and in fact, still believes in the pre-colonial era that evidence however collected is good. A good explanation of the same can be found here. There are some exceptions to the rule, but they are done so fine that more often than not, they can t be used in the court of law in India. Although a good RTI was shared by Mr. Saket Gokhale on the same issue, which does raise some interesting points
Twitter India Raid, Saket Gokhale RTI 1
Saket Gokhale RTI query , Twitter India Raid 2
FWIW, Saket has been successful in getting his prayers heard either as answers to RTI queries or then following it up in the various High Courts of India. Of course, those who are in the ruling party ridicule him but are unable to find faults in his application of logic. And quite a few times, I have learned from his applications as well as nuances or whatever is there in law, a judgment or a guideline which he invokes in his prayer. For e.g. the Lalitha Kumari Guidelines which the gentleman has shared in his prayer can be found here. Hence now, it would be upto the Delhi Police Cell to prove their case in response to RTI. He has also trapped them as he has shared they can t give excuses/exemptions which they have tried before. As I had shared earlier, High Courts in India have woken up, whether it is Delhi, Mumbai, Aurangabad, Madhya Pradesh, Uttar Pradesh, Odisha or Kerala. Just today i.e. on 25th May 2021, Justices Bela Trivedi and Justice Kalra had asked how come all the hospitals don t have NOC from the Fire De[partment. They also questioned the ASG (Assistant Solicitor General) as how BU (Building Use Certificate) has been granted as almost all the 400 hospitals are in residential area. To which the ASG replies, it is the same state in almost 4000 schools as well as 6000 odd factories in Ahemdabad alone, leave the rest of the district and state alone. And this is when last year strict instuctions were passed. They chose to do nothing sadly. I will share a link on this when bar and bench gives me The Hindu also shared the whole raid on twitter saga.

Conclusion In conclusion, I sincerely do not where we are headed. The only thing I know is that we cannot expect things to be better before year-end and maybe even after that. It all depends on the vaccines and their availability. After that ruralindia article, I had to see quite a few movies and whatnot just to get that out of my head. And this is apart from the 1600 odd teachers and workers who have died in the U.P. poll duty. Now, what a loss, not just to the family members of the victims, but a whole generation of school children who would not be able to get quality teaching and be deprived of education. What will be their future, God only knows. The only good Bollywood movie which I saw was Ramprasad ki Teravi . The movie was an accurate representation of most families in and around me. There was a movie called Sansar (1987) which showed the breakup of the joint family and into a nuclear family. This movie could very well have been a continuation of the same. Even Marathi movies which at one time were very progressive have gone back to the same boy, girl love story routine. Sameer, though released in late 2020, was able to see it only recently. Vakeel Saab was an ok copy of Pink . I loved Sameer as, unlike Salman Khan films, it showed pretty much an authentic human struggle of a person who goes to the Middle East without any qualifications and works as a laborer and the trials he goes through. Somehow, Malayalam movies have a knack for showing truth without much of budget. Most of the Indian web series didn t make an impact. I think many of them were just going through the motions, it seems as everybody is concerned with the well-being of their near and dear ones. There was also this (Trigger Warning: This story discusses organized campaigns glorifying and advocating sexual violence against Muslim women.) Hoping people somehow make it to the other side of the pandemic.

Antoine Beaupr : Leaving Freenode

The freenode IRC network has been hijacked. TL;DR: move to libera.chat or OFTC.net, as did countless free software projects including Gentoo, CentOS, KDE, Wikipedia, FOSDEM, and more. Debian and the Tor project were already on OFTC and are not affected by this.

What is freenode and why should I care? freenode is the largest remaining IRC network. Before this incident, it had close to 80,000 users, which is small in terms of modern internet history -- even small social networks are larger by multiple orders of magnitude -- but is large in IRC history. The IRC network is also extensively used by the free software community, being the default IRC network on many programs, and used by hundreds if not thousands of free software projects. I have been using freenode since at least 2006. This matters if you care about IRC, the internet, open protocols, decentralisation, and, to a certain extent, federation as well. It also touches on who has the right on network resources: the people who "own" it (through money) or the people who make it work (through their labor). I am biased towards open protocols, the internet, federation, and worker power, and this might taint this analysis.

What happened? It's a long story, but basically:
  1. back in 2017, the former head of staff sold the freenode.net domain (and its related company) to Andrew Lee, "American entrepreneur, software developer and writer", and, rather weirdly, supposedly "crown prince of Korea" although that part is kind of complex (see House of Yi, Yi Won, and Yi Seok). It should be noted the Korean Empire hasn't existed for over a century at this point (even though its flag, also weirdly, remains)
  2. back then, this was only known to the public as this strange PIA and freenode joining forces gimmick. it was suspicious at first, but since the network kept running, no one paid much attention to it. opers of the network were similarly reassured that Lee would have no say in the management of the network
  3. this all changed recently when Lee asserted ownership of the freenode.net domain and started meddling in the operations of the network, according to this summary. this part is disputed, but it is corroborated by almost a dozen former staff which collectively resigned from the network in protest, after legal threats, when it was obvious freenode was lost.
  4. the departing freenode staff founded a new network, irc.libera.chat, based on the new ircd they were working on with OFTC, solanum
  5. meanwhile, bot armies started attacking all IRC networks: both libera and freenode, but also OFTC and unrelated networks like a small one I help operate. those attacks have mostly stopped as of this writing (2021-05-24 17:30UTC)
  6. on freenode, however, things are going for the worse: Lee has been accused of taking over a channel, in a grotesque abuse of power; then changing freenode policy to not only justify the abuse, but also remove rules against hateful speech, effectively allowing nazis on the network (update: the change was reverted, but not by Lee)
Update: even though the policy change was reverted, the actual conversations allowed on freenode have already degenerated into toxic garbage. There are also massive channel takeovers (presumably over 700), mostly on channels that were redirecting to libera, but also channels that were still live. Channels that were taken over include #fosdem, #wikipedia, #haskell... Instead of working on the network, the new "so-called freenode" staff is spending effort writing bots and patches to basically automate taking over channels. I run an IRC network and this bot is obviously not standard "services" stuff... This is just grotesque. At this point I agree with this HN comment:
We should stop implicitly legitimizing Andrew Lee's power grab by referring to his dominion as "Freenode". Freenode is a quarter-century-old community that has changed its name to libera.chat; the thing being referred to here as "Freenode" is something else that has illegitimately acquired control of Freenode's old servers and user database, causing enormous inconvenience to the real Freenode.
I don't agree with the suggested name there, let's instead call it "so called freenode" as suggested later in the thread.

What now? I recommend people and organisations move away from freenode as soon as possible. This is a major change: documentation needs to be fixed, and the migration needs to be coordinated. But I do not believe we can trust the new freenode "owners" to operate the network reliably and in good faith. It's also important to use the current momentum to build a critical mass elsewhere so that people don't end up on freenode again by default and find an even more toxic community than your typical run-of-the-mill free software project (which is already not a high bar to meet). Update: people are moving to libera in droves. It's now reaching 18,000 users, which is bigger than OFTC and getting close to the largest, traditionnal, IRC networks (EFnet, Undernet, IRCnet are in the 10-20k users range). so-called freenode is still larger, currently clocking 68,000 users, but that's a huge drop from the previous count which was 78,000 before the exodus began. We're even starting to see the effects of the migration on netsplit.de. Update 2: the isfreenodedeadyet.com site is updated more frequently than netsplit and shows tons more information. It shows 25k online users for libera and 61k for so-called freenode (down from ~78k), and the trend doesn't seem to be stopping for so-called freenode. There's also a list of 400+ channels that have moved out. Keep in mind that such migrations take effect over long periods of time.

Where do I move to? The first thing you should do is to figure out which tool to use for interactive user support. There are multiple alternatives, of course -- this is the internet after all -- but here is a short list of suggestions, in preferred priority order:
  1. irc.libera.chat
  2. irc.OFTC.net
  3. Matrix.org, which bridges with OFTC and (hopefully soon) with libera as well, modern IRC alternative
  4. XMPP/Jabber also still exists, if you're into that kind of stuff, but I don't think the "chat room" story is great there, at least not as good as Matrix
Basically, the decision tree is this:
  • if you want to stay on IRC:
    • if you are already on many OFTC channels and few freenode channels: move to OFTC
    • if you are more inclined to support the previous freenode staff: move to libera
    • if you care about matrix users (in the short term): move to OFTC
  • if you are ready to leave IRC:
    • if you want the latest and greatest: move to Matrix
    • if you like XML and already use XMPP: move to XMPP
Frankly, at this point, everyone should seriously consider moving to Matrix. The user story is great, the web is a first class user, it supports E2EE (although XMPP as well), and has a lot of momentum behind it. It even bridges with IRC well (which is not the case for XMPP) so if you're worried about problems like this happening again. (Indeed, I wouldn't be surprised if similar drama happens on OFTC or libera in the future. The history of IRC is full of such epic controversies, takeovers, sabotage, attacks, technical flamewars, and other silly things. I am not sure, but I suspect a federated model like Matrix might be more resilient to conflicts like this one.) Changing protocols might mean losing a bunch of users however: not everyone is ready to move to Matrix, for example. Graybeards like me have been using irssi for years, if not decades, and would take quite a bit of convincing to move elsewhere. I have mostly kept my channels on IRC, and moved either to OFTC or libera. In retrospect, I think I might have moved everything to OFTC if I would have thought about it more, because almost all of my channels are there. But I kind of expect a lot of the freenode community to move to libera, so I am keeping a socket open there anyways.

How do I move? The first thing you should do is to update documentation, websites, and source code to stop pointing at freenode altogether. This is what I did for feed2exec, for example. You need to let people know in the current channel as well, and possibly shutdown the channel on freenode. Since my channels are either small or empty, I took the radical approach of:
  • redirecting the channel to ##unavailable which is historically the way we show channels have moved to another network
  • make the channel invite-only (which effectively enforces the redirection)
  • kicking everyone out of the channel
  • kickban people who rejoin
  • set the topic to announce the change
In IRC speak, the following commands should do all this: 
/msg ChanServ set #anarcat mlock +if ##unavailable
/msg ChanServ clear #anarcat users moving to irc.libera.chat
/msg ChanServ set #anarcat restricted on
/topic #anarcat this channel has moved to irc.libera.chat
If the channel is not registered, the following might work 
/mode #anarcat +if ##unavailable
Then you can leave freenode altogether: 
/disconnect Freenode unacceptable hijack, policy changes and takeovers. so long and thanks for all the fish.
Keep in mind that some people have been unable to setup such redirections, because the new freenode staff have taken over their channel, in which case you're out of luck... Some people have expressed concern about their private data hosted at freenode as well. If you care about this, you can always talk to NickServ and DROP your nick. Be warned, however, that this assumes good faith of the network operators, which, at this point, is kind of futile. I would assume any data you have registered on there (typically: your NickServ password and email address) to be compromised and leaked. If your password is used elsewhere (tsk, tsk), change it everywhere. Update: there's also another procedure, similar to the above, but with a different approach. Keep in mind that so-called freenode staff are actively hijacking channels for the mere act of mentioning libera in the channel topic, so thread carefully there.

Last words This is a sad time for IRC in general, and freenode in particular. It's a real shame that the previous freenode staff have been kicked out, and it's especially horrible that if the new policies of the network are basically making the network open to nazis. I wish things would have gone out differently: now we have yet another fork in the IRC history. While it's not the first time freenode changes name (it was called OPN before), now the old freenode is still around and this will bring much confusion to the world, especially since the new freenode staff is still claiming to support FOSS. I understand there are many sides to this story, and some people were deeply hurt by all this. But for me, it's completely unacceptable to keep pushing your staff so hard that they basically all (except one?) resign in protest. For me, that's leadership failure at the utmost, and a complete disgrace. And of course, I can't in good conscience support or join a network that allows hate speech. Regardless of the fate of whatever we'll call what's left of freenode, maybe it's time for this old IRC thing to die already. It's still a sad day in internet history, but then again, maybe IRC will never die...

Dirk Eddelbuettel: RcppArmadillo 0.10.5.0.0 on CRAN: New Upstream

armadillo image Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language and is widely used by (currently) 865 other packages on CRAN. This new release brings Armadillo 10.5.0 which was released early on Friday. We had done one full test in the 10.5 rc1 prerelease one week earlier, and did another test on 10.5.0 and this 0.10.5.0.0 RcppArmadillo release just for added rigour. The package was then uploaded to CRAN late Friday (my timezone). The automated process flagged one NOTE as a false positive (yet another instance of the well-known (yet dreaded) issue of Suggests != Depends by one these 865 packages). This lead to a need of an inspection by one of the CRAN maintainers, and the weekend being the weekend it was only processed just now. Upstream moves at a speed that is a little faster than the cadence CRAN likes. As we had released RcppArmadillo 0.10.4.0.0 on April 13 we did not want to follow-up too soon thereafter with 0.10.4.1.0 which was thusly only a GitHub and drat release (which can always be had easily too via install.packages("RcppArmadillo", repos="https://RcppCore.github.io/drat").) The full set of changes follows. We include the aforementioned interim release as well.

Changes in RcppArmadillo version 0.10.5.0 (2021-05-21)
  • Upgraded to Armadillo release 10.5 (Antipodean Fortress)
    • added .clamp() member function
    • expanded the standalone clamp() function to handle complex values
    • more efficient use of OpenMP
    • vector, matrix and cube constructors now initialise elements to zero by default; use the fill::none specifier, eg. mat X(4,5,fill::none), to disable element initialisation
  • Added codecov.yml to exclude Armadillo from coverage analysis

Changes in RcppArmadillo version 0.10.4.1.0 (2021-04-23)
  • Upgraded to Armadillo release 10.4.1 (Pressure Cooker)
  • GitHub-only release

Courtesy of my CRANberries, there is a diffstat report relative to previous release. More detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page. If you like this or other open-source work I do, you can sponsor me at GitHub.

Dirk Eddelbuettel: RcppDate 0.0.3: New Upstream

RcppDate wraps the featureful date library written by Howard Hinnant for use with R. This header-only modern C++ library has been in pretty wide-spread use for a while now, and adds to C++11/C++14/C++17 what will be (with minor modifications) the date library in C++20. Our previous 0.0.2 release already contained date version 3.0.0 from last year plus some of changes accumulated since then. Now that date 3.0.1 was just released, we are providing a quick sync with this version.

Changes in version 0.0.3 (2021-05-19)
  • Updated to upstream version 3.0.1

Dirk Eddelbuettel: inline 0.3.18: Routine Update

A new release of the inline package got to CRAN today. inline facilitates writing code in-line in simple string expressions or short files. The package was used quite extensively by Rcpp in the days before Rcpp Attributes arrived on the scene proving an even better alternative for its use cases. inline is still used by rstan and a number of other packages. Johannes Ranke, who uses and stresses inline via his package mkin, updated the loading/unloading of DLLs which, following updates in R-devel, was failing some tests. As luck will have it, this new version appears to still fail on two of the platforms we do not actually have easy access to so another version may be coming shortly . See below for a detailed list of changes extracted from the NEWS file.

Changes in inline version 0.3.18 (2021-05-17)
  • The moveDLL code and tests were updated for changed in R-devel (Johannes in #22 fixing #21).

Courtesy of my CRANberries, there is a comparison to the previous release. If you like this or other open-source work I do, you can now sponsor me at GitHub.

Vincent Fourmond: Tutorial: analyze redox inactivations/reactivations

Redox-dependent inactivations are actually rather common in the field of metalloenzymes, and electrochemistry can be an extremely powerful tool to study them, providing one can analyze the data quantitatively. The point of this point is to teach the reader how to do so using QSoas. For more general information about redox inactivations and how to study them using electrochemical techniques, the reader is invited to read the review del Barrio and Fourmond, ChemElectroChem 2019. This post is a tutorial to learn the analysis of data coming from the study of the redox-dependent substrate inhibition of periplasmic nitrate reductase NapAB, which has the advantage of being relatively simple. The whole processed is discussed in Jacques et al, BBA, 2014. What you need to know in order to follow this tutorial is the following: You can download the data files from the GitHub repository. Before fitting the data to determine the values of the rate constants at the potentials of the experiment, we will first subtract the background current, assuming that the respective contributions of faradaic and non-faradaic currents is additive. Start QSoas, go to the directory where you saved the files, and load both the data file and the blank file thus: 
QSoas> cd
QSoas> load 27.oxw
QSoas> load 27-blanc.oxw
QSoas> S 1 0
(after the first command, you have to manually select the directory in which you downloaded the data files). The S 1 0 command just subtracts the dataset 1 (the first loaded) from the dataset 0 (the last loaded), see more there. blanc is the French for blank... Then, we remove a bit of the beginning and the end of the data, corresponding to one half of the steps at \(E_0\), which we don't exploit much here (they are essentially only used to make sure that the irreversible loss is taken care of properly). This is done using strip-if: 
QSoas> strip-if x<30 x>300
Then, we can fit ! The fit used is called fit-linear-kinetic-system, which is used to fit kinetic models with only linear reactions (like here) and steps which change the values of the rate constants but do not instantly change the concentrations. The specific command to fit the data is: 
QSoas> fit-linear-kinetic-system /species=2 /steps=0,1,2,1,0
The /species=2 indicates that there are two species (A and I). The /steps=0,1,2,1,0 indicates that there are 5 steps, with three different conditions (0 to 2) in order 0,1,2,1,0. This fits needs a bit of setup before getting started. The species are numbered, 1 and 2, and the conditions (potentials) are indicated by #0, #1 and #2 suffixes. For the sake of simplicity, you can also simply load the starting-parameters.params parameters to have all setup the correct way. Then, just hit Fit, enjoy this moment when QSoas works and you don't have to... The screen should now look like this:
Now, it's done ! The fit is actually pretty good, and you can read the values of the inactivation and reactivation rate constants from the fit parameters. You can train also on the 21.oxw and 21-blanc.oxw files. Usually, re-loading the best fit parameters from other potentials as starting parameters work really well. Gathering the results of several fits into a real curve of rate constants as a function of potentials is left as an exercise for the reader (or maybe a later post), although you may find these series of posts useful in this context !
About QSoas QSoas is a powerful open source data analysis program that focuses on flexibility and powerful fitting capacities. It is released under the GNU General Public License. It is described in Fourmond, Anal. Chem., 2016, 88 (10), pp 5050 5052. Current version is 3.0. You can download its source code there (or clone from the GitHub repository) and compile it yourself, or buy precompiled versions for MacOS and Windows there.

Shirish Agarwal: Population, Immigration, Vaccines and Mass-Surveilance.

The Population Issue and its many facets Another couple of weeks passed. A Lot of things happening, lots of anger and depression in folks due to handling in pandemic, but instead of blaming they are willing to blame everybody else including the population. Many of them want forced sterilization like what Sanjay Gandhi did during the Emergency (1975). I had to share So Long, My son . A very moving tale of two families of what happened to them during the one-child policy in China. I was so moved by it and couldn t believe that the Chinese censors allowed it to be produced, shot, edited, and then shared worldwide. It also won a couple of awards at the 69th Berlin Film Festival, silver bear for the best actor and the actress in that category. But more than the award, the theme, and the concept as well as the length of the movie which was astonishing. Over a 3 hr. something it paints a moving picture of love, loss, shame, relief, anger, and asking for forgiveness. All of which can be identified by any rational person with feelings worldwide.

Girl child What was also interesting though was what it couldn t or wasn t able to talk about and that is the Chinese leftover men. In fact, a similar situation exists here in India, only it has been suppressed. This has been more pronounced more in Asia than in other places. One big thing in this is human trafficking and mostly women trafficking. For the Chinese male, that was happening on a large scale from all neighboring countries including India. This has been shared in media and everybody knows about it and yet people are silent. But this is not limited to just the Chinese, even Indians have been doing it. Even yesteryear actress Rupa Ganguly was caught red-handed but then later let off after formal questioning as she is from the ruling party. So much for justice. What is and has been surprising at least for me is Rwanda which is in the top 10 of some of the best places in equal gender. It, along with other African countries have also been in news for putting quite a significant amount of percentage of GDP into public healthcare (between 20-10%), but that is a story for a bit later. People forget or want to forget that it was in Satara, a city in my own state where 220 girls changed their name from nakusha or unwanted to something else and that had become a piece of global news. One would think that after so many years, things would have changed, the only change that has happened is that now we have two ministries, The Ministry of Women and Child Development (MoWCD) and The Ministry of Health and Welfare (MoHFW). Sadly, in both cases, the ministries have been found wanting, Whether it was the high-profile Hathras case or even the routine cries of help which given by women on the twitter helpline. Sadly, neither of these ministries talks about POSH guidelines which came up after the 2012 gangrape case. For both these ministries, it should have been a pinned tweet. There is also the 1994 PCPNDT Act which although made in 1994, actually functioned in 2006, although what happens underground even today nobody knows . On the global stage, about a decade ago, Stephen J. Dubner and Steven Levitt argued in their book Freakonomics how legalized abortion both made the coming population explosion as well as expected crime rates to be reduced. There was a huge pushback on the same from the conservatives and has become a matter of debate, perhaps something that the Conservatives wanted. Interestingly, it hasn t made them go back but go forward as can be seen from the Freakonomics site.

Climate Change Another topic that came up for discussion was repeatedly climate change, but when I share Shell s own 1998 Confidential report titled Greenhouse effect all become strangely silent. The silence here is of two parts, there probably is a large swathe of Indians who haven t read the report and there may be a minority who have read it and know what already has been shared with U.S. Congress. The Conservative s argument has been for it is jobs and a weak we need to research more . There was a partial debunk of it on the TBD podcast by Matt Farell and his brother Sean Farell as to how quickly the energy companies are taking to the coming change.

Health Budget Before going to Covid stories. I first wanted to talk about Health Budgets. From the last 7 years the Center s allocation for health has been between 0.34 to 0.8% per year. That amount barely covers the salaries to the staff, let alone any money for equipment or anything else. And here by allocation I mean, what is actually spent, not the one that is shared by GOI as part of budget proposal. In fact, an article on Wire gives a good breakdown of the numbers. Even those who are on the path of free markets describe India s health business model as a flawed one. See the Bloomberg Quint story on that. Now let me come to Rwanda. Why did I chose Rwanda, I could have chosen South Africa where I went for Debconf 2016, I chose because Rwanda s story is that much more inspiring. In many ways much more inspiring than that South Africa in many ways. Here is a country which for decades had one war or the other, culminating into the Rwanda Civil War which ended in 1994. And coincidentally, they gained independence on a similar timeline as South Africa ending Apartheid in 1994. What does the country do, when it gains its independence, it first puts most of its resources in the healthcare sector. The first few years at 20% of GDP, later than at 10% of GDP till everybody has universal medical coverage. Coming back to the Bloomberg article I shared, the story does not go into the depth of beyond-expiry date medicines, spurious medicines and whatnot. Sadly, most media in India does not cover the deaths happening in rural areas and this I am talking about normal times. Today what is happening in rural areas is just pure madness. For last couple of days have been talking with people who are and have been covering rural areas. In many of those communities, there is vaccine hesitancy and why, because there have been whatsapp forwards sharing that if you go to a hospital you will die and your kidney or some other part of the body will be taken by the doctor. This does two things, it scares people into not going and getting vaccinated, at the same time they are prejudiced against science. This is politics of the lowest kind. And they do it so that they will be forced to go to temples or babas and what not and ask for solutions. And whether they work or not is immaterial, they get fixed and property and money is seized. Sadly, there are not many Indian movies of North which have tried to show it except for oh my god but even here it doesn t go the distance. A much more honest approach was done in Trance . I have never understood how the South Indian movies are able to do a more honest job of story-telling than what is done in Bollywood even though they do in 1/10th the budget that is needed in Bollywood. Although, have to say with OTT, some baggage has been shed but with the whole film certification rearing its ugly head through MEITY orders, it seems two steps backward instead of forward. The idea being simply to infantilize the citizens even more. That is a whole different ball-game which probably will require its own space.

Vaccine issues One good news though is that Vaccination has started. But it has been a long story full of greed by none other than GOI (Government of India) or the ruling party BJP. Where should I start with. I probably should start with this excellent article done by Priyanka Pulla. It is interesting and fascinating to know how vaccines are made, at least one way which she shared. She also shared about the Cutter Incident which happened in the late 50 s. The response was on expected lines, character assassination of her and the newspaper they published but could not critique any of the points made by her. Not a single point that she didn t think about x or y. Interestingly enough, in January 2021 Bharati Biotech was supposed to be share phase 3 trial data but hasn t been put up in public domain till May 2021. In fact, there have been a few threads raised by both well-meaning Indians as well as others globally especially on twitter to which GOI/ICMR (Indian Council of Medical Research) is silent. Another interesting point to note is that Russia did say in its press release that it is possible that their vaccine may not be standard (read inactivation on their vaccines and another way is possible but would take time, again Brazil has objected, but India hasn t till date.) What also has been interesting is the homegrown B.1.617 lineage or known as double mutant . This was first discovered from my own state, Maharashtra and then transported around the world. There is also B.1.618 which was found in West Bengal and is same or supposed to be similar to the one found in South Africa. This one is known as Triple mutant . About B.1.618 we don t know much other than knowing that it is much more easily transferable, much more infectious. Most countries have banned flights from India and I cannot fault them anyway. Hell, when even our diplomats do not care for procedures to be followed during the pandemic then how a common man is supposed to do. Of course, now for next month, Mr. Modi was supposed to go and now will not attend the G7 meeting. Whether, it is because he would have to face the press (the only Prime Minister and the only Indian Prime Minister who never has faced free press.) or because the Indian delegation has been disinvited, we would never know.

A good article which shares lots of lows with how things have been done in India has been an article by Arundhati Roy. And while the article in itself is excellent and shares a bit of the bitter truth but is still incomplete as so much has been happening. The problem is that the issue manifests in so many ways, it is difficult to hold on. As Arundhati shared, should we just look at figures and numbers and hold on, or should we look at individual ones, for e.g. the one shared in Outlook India. Or the one shared by Dr. Dipshika Ghosh who works in Covid ICU in some hospital
Dr. Dipika Ghosh sharing an incident in Covid Ward

Interestingly as well, while in the vaccine issue, Brazil Anvisa doesn t know what they are doing or the regulator just isn t knowledgeable etc. (statements by various people in GOI, when it comes to testing kits, the same is an approver.)

ICMR/DGCI approving internationally validated kits, Press release.

Twitter In the midst of all this, one thing that many people have forgotten and seem to have forgotten that Twitter and other tools are used by only the elite. The reason why the whole thing has become serious now than in the first phase is because the elite of India have also fallen sick and dying which was not the case so much in the first phase. The population on Twitter is estimated to be around 30-34 million and people who are everyday around 20 odd million or so, which is what 2% of the Indian population which is estimated to be around 1.34 billion. The other 98% don t even know that there is something like twitter on which you can ask help. Twitter itself is exclusionary in many ways, with both the emoticons, the language and all sorts of things. There is a small subset who does use Twitter in regional languages, but they are too small to write anything about. The main language is English which does become a hindrance to lot of people.

Censorship Censorship of Indians critical of Govt. mishandling has been non-stop. Even U.S. which usually doesn t interfere into India s internal politics was forced to make an exception. But of course, this has been on deaf ears. There is and was a good thread on Twitter by Gaurav Sabnis, a friend, fellow Puneite now settled in U.S. as a professor.
Gaurav on Trump-Biden on vaccination of their own citizens
Now just to surmise what has been happened in India and what has been happening in most of the countries around the world. Most of the countries have done centralization purchasing of the vaccine and then is distributed by the States, this is what we understand as co-operative federalism. While last year, GOI took a lot of money under the shady PM Cares fund for vaccine purchase, donations from well-meaning Indians as well as Industries and trade bodies. Then later, GOI said it would leave the states hanging and it is they who would have to buy vaccines from the manufacturers. This is again cheap politics. The idea behind it is simple, GOI knows that almost all the states are strapped for cash. This is not new news, this I have shared a couple of months back. The problem has been that for the last 6-8 months no GST meeting has taken place as shared by Punjab s Finance Minister Amarinder Singh. What will happen is that all the states will fight in-between themselves for the vaccine and most of them are now non-BJP Governments. The idea is let the states fight and somehow be on top. So, the pandemic, instead of being a public health issue has become something of on which politics has to played. The news on whatsapp by RW media is it s ok even if a million or two also die, as it is India is heavily populated. Although that argument vanishes for those who lose their dear and near ones. But that just isn t the issue, the issue goes much more deeper than that Oxygen:12%
Remedisivir:12%
Sanitiser:12%
Ventilator:12%
PPE:18%
Ambulances 28% Now all the products above are essential medical equipment and should be declared as essential medical equipment and should have price controls on which GST is levied. In times of pandemic, should the center be profiting on those. States want to let go and even want the center to let go so that some relief is there to the public, while at the same time make them as essential medical equipment with price controls. But GOI doesn t want to. Leaders of opposition parties wrote open letters but no effect. What is sad to me is how Ambulances are being taxed at 28%. Are they luxury items or sin goods ? This also reminds of the recent discovery shared by Mr. Pappu Yadav in Bihar. You can see the color of ambulances as shared by Mr. Yadav, and the same news being shared by India TV news showing other ambulances. Also, the weak argument being made of not having enough drivers. Ideally, you should have 2-3 people, both 9-1-1 and Chicago Fire show 2 people in ambulance but a few times they have also shown to be flipped over. European seems to have three people in ambulance, also they are also much more disciplined as drivers, at least an opinion shared by an American expat.

What is also interesting to note is GOI plays this game of Health is State subject and health is Central subject depending on its convenience. Last year, when it invoked the Epidemic and DMA Act it was a Central subject, now when bodies are flowing down the Ganges and pyres being lit everywhere, it becomes a State subject. But when and where money is involved, it again becomes a Central subject. The States are also understanding it, but they are fighting on too many fronts.
Snippets from Karnataka High Court hearing today, 13th March 2021
One of the good things is most of the High Courts have woken up. Many of the people on the RW think that the Courts are doing Judicial activism . And while there may be an iota of truth in it, the bitter truth is that many judges or relatives or their helpers have diagnosed and some have even died due to Covid. In face of the inevitable, what can they do. They are hauling up local Governments to make sure they are accountable while at the same time making sure that they get access to medical facilities. And I as a citizen don t see any wrong in that even if they are doing it for selfish reasons. Because, even if justice is being done for selfish reasons, if it does improve medical delivery systems for the masses, it is cool. If it means that the poor and everybody else are able to get vaccinations, oxygen and whatever they need, it is cool. Of course, we are still seeing reports of patients spending in the region of INR 50k and more for each day spent in hospital. But as there are no price controls, judges cannot do anything unless they want to make an enemy of the medical lobby in the country. A good story on medicines and what happens in rural areas, see no further than Laakhon mein ek.
Allahabad High Court hauling Uttar Pradesh Govt. for lack of Oxygen is equal to genocide, May 11, 2021
The censorship is not just related to takedown requests on twitter but nowadays also any articles which are critical of the GOI s handling. I have been seeing many articles which have shared facts and have been critical of GOI being taken down. Previously, we used to see 404 errors happen 7-10 years down the line and that was reasonable. Now we see that happen, days weeks or months. India seems to be turning more into China and North Korea and become more anti-science day-by-day

Fake websites Before going into fake websites, let me start with a fake newspaper which was started by none other than the Gujarat CM Mr. Modi in 2005 .
Gujarat Satya Samachar 2005 launched by Mr. Modi.
And if this wasn t enough than on Feb 8, 2005, he had invoked Official Secrets Act
Mr. Modi invoking Official Secrets Act, Feb 8 2005 Gujarat Samachar
The headlines were In Modi s regime press freedom is in peril-Down with Modi s dictatorship. So this was a tried and tested technique. The above information was shared by Mr. Urvish Kothari, who incidentally also has his own youtube channel. Now cut to 2021, and we have a slew of fake websites being done by the same party. In fact, it seems they started this right from 2011. A good article on BBC itself tells the story. Hell, Disinfo.eu which basically combats disinformation in EU has a whole pdf chronicling how BJP has been doing it. Some of the sites it shared are

Times of New York
Manchester Times
Times of Los Angeles
Manhattan Post
Washington Herald
and many more. The idea being take any site name which sounds similar to a brand name recognized by Indians and make fool of them. Of course, those of who use whois and other such tools can easily know what is happening. Two more were added to the list yesterday, Daily Guardian and Australia Today. There are of course, many features which tell them apart from genuine websites. Most of these are on shared hosting rather than dedicated hosting, most of these are bought either from Godaddy and Bluehost. While Bluehost used to be a class act once upon a time, both the above will do anything as long as they get money. Don t care whether it s a fake website or true. Capitalism at its finest or worst depending upon how you look at it. But most of these details are lost on people who do not know web servers, at all and instead think see it is from an exotic site, a foreign site and it chooses to have same ideas as me. Those who are corrupt or see politics as a tool to win at any cost will not see it as evil. And as a gentleman Raghav shared with me, it is so easy to fool us. An example he shared which I had forgotten. Peter England which used to be an Irish brand was bought by Aditya Birla group way back in 2000. But even today, when you go for Peter England, the way the packaging is done, the way the prices are, more often than not, people believe they are buying the Irish brand. While sharing this, there is so much of Naom Chomsky which comes to my mind again and again

Caste Issues I had written about caste issues a few times on this blog. This again came to the fore as news came that a Hindu sect used forced labor from Dalit community to make a temple. This was also shared by the hill. In both, Mr. Joshi doesn t tell that if they were volunteers then why their passports have been taken forcibly, also I looked at both minimum wage prevailing in New Jersey as a state as well as wage given to those who are in the construction Industry. Even in minimum wage, they were giving $1 when the prevailing minimum wage for unskilled work is $12.00 and as Mr. Joshi shared that they are specialized artisans, then they should be paid between $23 $30 per hour. If this isn t exploitation, then I don t know what is. And this is not the first instance, the first instance was perhaps the case against Cisco which was done by John Doe. While I had been busy with other things, it seems Cisco had put up both a demurrer petition and a petition to strike which the Court stayed. This seemed to all over again a type of apartheid practice, only this time applied to caste. The good thing is that the court stayed the petition. Dr. Ambedkar s statement if Hindus migrate to other regions on earth, Indian caste would become a world problem given at Columbia University in 1916, seems to be proven right in today s time and sadly has aged well. But this is not just something which is there only in U.S. this is there in India even today, just couple of days back, a popular actress Munmun Dutta used a casteist slur and then later apologized giving the excuse that she didn t know Hindi. And this is patently false as she has been in the Bollywood industry for almost now 16-17 years. This again, was not an isolated incident. Seema Singh, a lecturer in IIT-Kharagpur abused students from SC, ST backgrounds and was later suspended. There is an SC/ST Atrocities Act but that has been diluted by this Govt. A bit on the background of Dr. Ambedkar can be found at a blog on Columbia website. As I have shared and asked before, how do we think, for what reason the Age of Englightenment or the Age of Reason happened. If I were a fat monk or a priest who was privileges, would I have let Age of Enlightenment happen. It broke religion or rather Church which was most powerful to not so powerful and that power was more distributed among all sort of thinkers, philosophers, tinkers, inventors and so on and so forth.

Situation going forward I believe things are going to be far more complex and deadly before they get better. I had to share another term called Comorbidities which fortunately or unfortunately has also become part of twitter lexicon. While I have shared what it means, it simply means when you have an existing ailment or condition and then Coronavirus attacks you. The Virus will weaken you. The Vaccine in the best case just stops the damage, but the damage already done can t be reversed. There are people who advise and people who are taking steroids but that again has its own side-effects. And this is now, when we are in summer. I am afraid for those who have recovered, what will happen to them during the Monsoons. We know that the Virus attacks most the lungs and their quality of life will be affected. Even the immune system may have issues. We also know about the inflammation. And the grant that has been given to University of Dundee also has signs of worry, both for people like me (obese) as well as those who have heart issues already. In other news, my city which has been under partial lockdown since a month, has been extended for another couple of weeks. There are rumors that the same may continue till the year-end even if it means economics goes out of the window.There is possibility that in the next few months something like 2 million odd Indians could die
The above is a conversation between Karan Thapar and an Oxford Mathematician Dr. Murad Banaji who has shared that the under-counting of cases in India is huge. Even BBC shared an article on the scope of under-counting. Of course, those on the RW call of the evidence including the deaths and obituaries in newspapers as a narrative . And when asked that when deaths used to be in the 20 s or 30 s which has jumped to 200-300 deaths and this is just the middle class and above. The poor don t have the money to get wood and that is the reason you are seeing the bodies in Ganges whether in Buxar Bihar or Gajipur, Uttar Pradesh. The sights and visuals makes for sorry reading
Pandit Ranjan Mishra son on his father s death due to unavailability of oxygen, Varanasi, Uttar Pradesh, 11th May 2021.
For those who don t know Pandit Ranjan Mishra was a renowned classical singer. More importantly, he was the first person to suggest Mr. Modi s name as a Prime Ministerial Candidate. If they couldn t fulfil his oxygen needs, then what can be expected for the normal public.

Conclusion Sadly, this time I have no humorous piece to share, I can however share a documentary which was shared on Feluda . I have shared about Feluda or Prodosh Chandra Mitter a few times on this blog. He has been the answer of James Bond from India. I have shared previously about The Golden Fortress . An amazing piece of art by Satyajit Ray. I watched that documentary two-three times. I thought, mistakenly that I am the only fool or fan of Feluda in Pune to find out that there are people who are even more than me. There were so many facets both about Feluda and master craftsman Satyajit Ray that I was unaware about. I was just simply amazed. I even shared few of the tidbits with mum as well, although now she has been truly hooked to Korean dramas. The only solace from all the surrounding madness. So, if you have nothing to do, you can look up his books, read them and then see the movies. And my first recommendation would be the Golden Fortress. The only thing I would say, do not have high hopes. The movie is beautiful. It starts slow and then picks up speed, just like a train. So, till later. Update The Mass surveillance part I could not do justice do hence removed it at the last moment. It actually needs its whole space, article. There is so much that the Govt. is doing under the guise of the pandemic that it is difficult to share it all in one article. As it is, the article is big

Ben Hutchings: Debian LTS work, April 2021

In April I was assigned 16 hours of work by Freexian's Debian LTS initiative and carried over 2.5 hours from earlier months. I worked 14 hours and will carry over the remainder. I spent a long time trying to verify that the futex issue in was now properly fixed in Linux 4.9, and reviewing the merge of these changes with the real-time (PREEMPT_RT) kernel patchset. Unfortunately this work is not complete and I did not make another upload this month.
