Russ Allbery: Review: The Fund

Review: The Fund, by Rob Copeland

Publisher:	St. Martin's Press

Format:	Kindle
Pages:	310

I first became aware of Ray Dalio when either he or his publisher plastered advertisements for The Principles all over the San Francisco 4th and King Caltrain station. If I recall correctly, there were also constant radio commercials; it was a whole thing in 2017. My brain is very good at tuning out advertisements, so my only thought at the time was "some business guy wrote a self-help book." I think I vaguely assumed he was a CEO of some traditional business, since that's usually who writes heavily marketed books like this. I did not connect him with hedge funds or Bridgewater, which I have a bad habit of confusing with Blackwater. The Principles turns out to be more of a laundered cult manual than a self-help book. And therein lies a story. Rob Copeland is currently with The New York Times, but for many years he was the hedge fund reporter for The Wall Street Journal. He covered, among other things, Bridgewater Associates, the enormous hedge fund founded by Ray Dalio. The Fund is a biography of Ray Dalio and a history of Bridgewater from its founding as a vehicle for Dalio's advising business until 2022 when Dalio, after multiple false starts and title shuffles, finally retired from running the company. (Maybe. Based on the history recounted here, it wouldn't surprise me if he was back at the helm by the time you read this.) It is one of the wildest, creepiest, and most abusive business histories that I have ever read. It's probably worth mentioning, as Copeland does explicitly, that Ray Dalio and Bridgewater hate this book and claim it's a pack of lies. Copeland includes some of their denials (and many non-denials that sound as good as confirmations to me) in footnotes that I found increasingly amusing.

A lawyer for Dalio said he "treated all employees equally, giving people at all levels the same respect and extending them the same perks."

Uh-huh. Anyway, I personally know nothing about Bridgewater other than what I learned here and the occasional mention in Matt Levine's newsletter (which is where I got the recommendation for this book). I have no independent information whether anything Copeland describes here is true, but Copeland provides the typical extensive list of notes and sourcing one expects in a book like this, and Levine's comments indicated it's generally consistent with Bridgewater's industry reputation. I think this book is true, but since the clear implication is that the world's largest hedge fund was primarily a deranged cult whose employees mostly spied on and rated each other rather than doing any real investment work, I also have questions, not all of which Copeland answers to my satisfaction. But more on that later. The center of this book are the Principles. These were an ever-changing list of rules and maxims for how people should conduct themselves within Bridgewater. Per Copeland, although Dalio later published a book by that name, the version of the Principles that made it into the book was sanitized and significantly edited down from the version used inside the company. Dalio was constantly adding new ones and sometimes changing them, but the common theme was radical, confrontational "honesty": never being silent about problems, confronting people directly about anything that they did wrong, and telling people all of their faults so that they could "know themselves better." If this sounds like textbook abusive behavior, you have the right idea. This part Dalio admits to openly, describing Bridgewater as a firm that isn't for everyone but that achieves great results because of this culture. But the uncomfortably confrontational vibes are only the tip of the iceberg of dysfunction. Here are just a few of the ways this played out according to Copeland:

Dalio decided that everyone's opinions should be weighted by the accuracy of their previous decisions, to create a "meritocracy," and therefore hired people to build a social credit system in which people could use an app to constantly rate all of their co-workers. This almost immediately devolved into out-group bullying worthy of a high school, with employees hurriedly down-rating and ostracizing any co-worker that Dalio down-rated.
When an early version of the system uncovered two employees at Bridgewater with more credibility than Dalio, Dalio had the system rigged to ensure that he always had the highest ratings and was not affected by other people's ratings.
Dalio became so obsessed with the principle of confronting problems that he created a centralized log of problems at Bridgewater and required employees find and report a quota of ten or twenty new issues every week or have their bonus docked. He would then regularly pick some issue out of the issue log, no matter how petty, and treat it like a referendum on the worth of the person responsible for the issue.
Dalio's favorite way of dealing with a problem was to put someone on trial. This involved extensive investigations followed by a meeting where Dalio would berate the person and harshly catalog their flaws, often reducing them to tears or panic attacks, while smugly insisting that having an emotional reaction to criticism was a personality flaw. These meetings were then filmed and added to a library available to all Bridgewater employees, often edited to remove Dalio's personal abuse and to make the emotional reaction of the target look disproportionate. The ones Dalio liked the best were shown to all new employees as part of their training in the Principles.
One of the best ways to gain institutional power in Bridgewater was to become sycophantically obsessed with the Principles and to be an eager participant in Dalio's trials. The highest levels of Bridgewater featured constant jockeying for power, often by trying to catch rivals in violations of the Principles so that they would be put on trial.

In one of the common and all-too-disturbing connections between Wall Street finance and the United States' dysfunctional government, James Comey (yes, that James Comey) ran internal security for Bridgewater for three years, meaning that he was the one who pulled evidence from surveillance cameras for Dalio to use to confront employees during his trials. In case the cult vibes weren't strong enough already, Bridgewater developed its own idiosyncratic language worthy of Scientology. The trials were called "probings," firing someone was called "sorting" them, and rating them was called "dotting," among many other Bridgewater-specific terms. Needless to say, no one ever probed Dalio himself. You will also be completely unsurprised to learn that Copeland documents instances of sexual harassment and discrimination at Bridgewater, including some by Dalio himself, although that seems to be a relatively small part of the overall dysfunction. Dalio was happy to publicly humiliate anyone regardless of gender. If you're like me, at this point you're probably wondering how Bridgewater continued operating for so long in this environment. (Per Copeland, since Dalio's retirement in 2022, Bridgewater has drastically reduced the cult-like behaviors, deleted its archive of probings, and de-emphasized the Principles.) It was not actually a religious cult; it was a hedge fund that has to provide investment services to huge, sophisticated clients, and by all accounts it's a very successful one. Why did this bizarre nightmare of a workplace not interfere with Bridgewater's business? This, I think, is the weakest part of this book. Copeland makes a few gestures at answering this question, but none of them are very satisfying. First, it's clear from Copeland's account that almost none of the employees of Bridgewater had any control over Bridgewater's investments. Nearly everyone was working on other parts of the business (sales, investor relations) or on cult-related obsessions. Investment decisions (largely incorporated into algorithms) were made by a tiny core of people and often by Dalio himself. Bridgewater also appears to not trade frequently, unlike some other hedge funds, meaning that they probably stay clear of the more labor-intensive high-frequency parts of the business. Second, Bridgewater took off as a hedge fund just before the hedge fund boom in the 1990s. It transformed from Dalio's personal consulting business and investment newsletter to a hedge fund in 1990 (with an earlier investment from the World Bank in 1987), and the 1990s were a very good decade for hedge funds. Bridgewater, in part due to Dalio's connections and effective marketing via his newsletter, became one of the largest hedge funds in the world, which gave it a sort of institutional momentum. No one was questioned for putting money into Bridgewater even in years when it did poorly compared to its rivals. Third, Dalio used the tried and true method of getting free publicity from the financial press: constantly predict an upcoming downturn, and aggressively take credit whenever you were right. From nearly the start of his career, Dalio predicted economic downturns year after year. Bridgewater did very well in the 2000 to 2003 downturn, and again during the 2008 financial crisis. Dalio aggressively takes credit for predicting both of those downturns and positioning Bridgewater correctly going into them. This is correct; what he avoids mentioning is that he also predicted downturns in every other year, the majority of which never happened. These points together create a bit of an answer, but they don't feel like the whole picture and Copeland doesn't connect the pieces. It seems possible that Dalio may simply be good at investing; he reads obsessively and clearly enjoys thinking about markets, and being an abusive cult leader doesn't take up all of his time. It's also true that to some extent hedge funds are semi-free money machines, in that once you have a sufficient quantity of money and political connections you gain access to investment opportunities and mechanisms that are very likely to make money and that the typical investor simply cannot access. Dalio is clearly good at making personal connections, and invested a lot of effort into forming close ties with tricky clients such as pools of Chinese money. Perhaps the most compelling explanation isn't mentioned directly in this book but instead comes from Matt Levine. Bridgewater touts its algorithmic trading over humans making individual trades, and there is some reason to believe that consistently applying an algorithm without regard to human emotion is a solid trading strategy in at least some investment areas. Levine has asked in his newsletter, tongue firmly in cheek, whether the bizarre cult-like behavior and constant infighting is a strategy to distract all the humans and keep them from messing with the algorithm and thus making bad decisions. Copeland leaves this question unsettled. Instead, one comes away from this book with a clear vision of the most dysfunctional workplace I have ever heard of, and an endless litany of bizarre events each more astonishing than the last. If you like watching train wrecks, this is the book for you. The only drawback is that, unlike other entries in this genre such as Bad Blood or Billion Dollar Loser, Bridgewater is a wildly successful company, so you don't get the schadenfreude of seeing a house of cards collapse. You do, however, get a helpful mental model to apply to the next person who tries to talk to you about "radical honesty" and "idea meritocracy." The flaw in this book is that the existence of an organization like Bridgewater is pointing to systematic flaws in how our society works, which Copeland is largely uninterested in interrogating. "How could this have happened?" is a rather large question to leave unanswered. The sheer outrageousness of Dalio's behavior also gets a bit tiring by the end of the book, when you've seen the patterns and are hearing about the fourth variation. But this is still an astonishing book, and a worthy entry in the genre of capitalism disasters. Rating: 7 out of 10

Ian Jackson: UPS, the Useless Parcel Service; VAT and fees

I recently had the most astonishingly bad experience with UPS, the courier company. They severely damaged my parcels, and were very bad about UK import VAT, ultimately ending up harassing me on autopilot. The only thing that got their attention was my draft Particulars of Claim for intended legal action. Surprisingly, I got them to admit in writing that the disbursement fee they charge recipients alongside the actual VAT, is just something they made up with no legal basis. What happened Autumn last year I ordered some furniture from a company in Germany. This was to be shipped by them to me by courier. The supplier chose UPS. UPS misrouted one of the three parcels to Denmark. When everything arrived, it had been sat on by elephants. The supplier had to replace most of it, with considerable inconvenience and delay to me, and of course a loss to the supplier. But this post isn t mostly about that. This post is about VAT. You see, import VAT was due, because of fucking Brexit. UPS made a complete hash of collecting that VAT. Their computers can t issue coherent documents, their email helpdesk is completely useless, and their automated debt collection systems run along uninfluenced by any external input. The crazy, including legal threats and escalating late payment fees, continued even after I paid the VAT discrepancy (which I did despite them not yet having provided any coherent calculation for it). This kind of behaviour is a very small and mild version of the kind of things British Gas did to Lisa Ferguson, who eventually won substantial damages for harassment, plus 10K of costs. Having tried asking nicely, and sending stiff letters, I too threatened litigation. I would have actually started a court claim, but it would have included a claim under the Protection from Harassment Act. Those have to be filed under the Part 8 procedure , which involves sending all of the written evidence you re going to use along with the claim form. Collating all that would be a good deal of work, especially since UPS and ControlAccount didn t engage with me at all, so I had no idea which things they might actually dispute. So I decided that before issuing proceedings, I d send them a copy of my draft Particulars of Claim, along with an offer to settle if they would pay me a modest sum and stop being evil robots at me. Rather than me typing the whole tale in again, you can read the full gory details in the PDF of my draft Particulars of Claim. (I ve redacted the reference numbers). Outcome The draft Particulars finally got their attention. UPS sent me an offer: they agreed to pay me 50, in full and final settlement. That was close enough to my offer that I accepted it. I mostly wanted them to stop, and they do seem to have done so. And I ve received the 50. VAT calculation They also finally included an actual explanation of the VAT calculation. It s absurd, but it s not UPS s absurd:

The clearance was entered initially with estimated import charges of 400.03, consisting of 387.83 VAT, and 12.20 disbursement fee. This original entry regrettably did not include the freight cost for calculating the VAT, and as such when submitted for final entry the VAT value was adjusted to include this and an amended invoice was issued for an additional 39.84. HMRC calculate the amount against which VAT is raised using the value of goods, insurance and freight, however they also may apply a VAT adjustment figure. The VAT Adjustment is based on many factors (Incidental costs in regards to a shipment), which includes charge for currency conversion if the invoice does not list values in Sterling, but the main is due to the inland freight from airport of destination to the final delivery point, as this charge varies, for example, from EMA to Edinburgh would be 150, from EMA to Derby would be 1, so each year UPS must supply HMRC with all values incurred for entry build up and they give an average which UPS have to use on the entry build up as the VAT Adjustment. The correct calculation for the import charges is therefore as follows: Goods value divided by exchange rate 2,489.53 EUR / 1.1683 = 2,130.89 GBP Duty: Goods value plus freight (%) 2,130.89 GBP + 5% = 2,237.43 GBP. That total times the duty rate. X 0 % = 0 GBP VAT: Goods value plus freight (100%) 2,130.89 GBP + 0 = 2,130.89 GBP That total plus duty and VAT adjustment 2,130.89 GBP + 0 GBP + 7.49 GBP = 2,348.08 GBP. That total times 20% VAT = 427.67 GBP As detailed above we must confirm that the final VAT charges applied to the shipment were correct, and that no refund of this is therefore due.

This looks very like HMRC-originated nonsense. If only they had put it on the original bills! It s completely ridiculous that it took four months and near-litigation to obtain it. Disbursement fee One more thing. UPS billed me a 12 disbursement fee . When you import something, there s often tax to pay. The courier company pays that to the government, and the consignee pays it to the courier. Usually the courier demands it before final delivery, since otherwise they end up having to chase it as a debt. It is common for parcel companies to add a random fee of their own. As I note in my Particulars, there isn t any legal basis for this. In my own offer of settlement I proposed that UPS should:

State under what principle of English law (such as, what enactment or principle of Common Law), you levy the disbursement fee (or refund it).

To my surprise they actually responded to this in their own settlement letter. (They didn t, for example, mention the harassment at all.) They said (emphasis mine):

A disbursement fee is a fee for amounts paid or processed on behalf of a client. It is an established category of charge used by legal firms, amongst other companies, for billing of various ancillary costs which may be incurred in completion of service. Disbursement fees are not covered by a specific law, nor are they legally prohibited. Regarding UPS disbursement fee this is an administrative charge levied for the use of UPS deferment account to prepay import charges for clearance through CDS. This charge would therefore be billed to the party that is responsible for the import charges, normally the consignee or receiver of the shipment in question. The disbursement fee as applied is legitimate, and as you have stated is a commonly used and recognised charge throughout the courier industry, and I can confirm that this was charged correctly in this instance.

On UPS s analysis, they can just make up whatever fee they like. That is clearly not right (and I don t even need to refer to consumer protection law, which would also make it obviously unlawful). And, that everyone does it doesn t make it lawful. There are so many things that are ubiquitous but unlawful, especially nowadays when much of the legal system - especially consumer protection regulators - has been underfunded to beyond the point of collapse. Next time this comes up I might have a go at getting the fee back. (Obviously I ll have to pay it first, to get my parcel.) ParcelForce and Royal Mail I think this analysis doesn t apply to ParcelForce and (probably) Royal Mail. I looked into this in 2009, and I found that Parcelforce had been given the ability to write their own private laws: Schemes made under section 89 of the Postal Services Act 2000. This is obviously ridiculous but I think it was the law in 2009. I doubt the intervening governments have fixed it. Furniture Oh, yes, the actual furniture. The replacements arrived intact and are great :-).

Michael Ablassmeier: qmpbackup 0.28

Over the last weekend i had some spare time to improve qmpbackup a little more, the new version:

Uses blockdev-backup QMP commands instead of the soon to be deprecated drive-backup.
Adds --compress option: target QCOW files data can be compressed.
Adds --speed-limit option to limit backup speed throughput.
Adds --include-raw option so attached raw devices can be backed up too.
Allows backing up virtual machines in paused or pre-running state.
Adds backup option copy to allow backing up virtual machines with older qcow image formats, that are not supporting persistent bitmaps.
Improved logging output.

and some minor code reworks. Hope its useful for someone.

Joachim Breitner: GHC Steering Committee Retrospective

After seven years of service as member and secretary on the GHC Steering Committee, I have resigned from that role. So this is a good time to look back and retrace the formation of the GHC proposal process and committee. In my memory, I helped define and shape the proposal process, optimizing it for effectiveness and throughput, but memory can be misleading, and judging from the paper trail in my email archives, this was indeed mostly Ben Gamari s and Richard Eisenberg s achievement: Already in Summer of 2016, Ben Gamari set up the ghc-proposals Github repository with a sketch of a process and sent out a call for nominations on the GHC user s mailing list, which I replied to. The Simons picked the first set of members, and in the fall of 2016 we discussed the committee s by-laws and procedures. As so often, Richard was an influential shaping force here.

Three ingredients For example, it was him that suggested that for each proposal we have one committee member be the Shepherd , overseeing the discussion. I believe this was one ingredient for the process effectiveness: There is always one person in charge, and thus we avoid the delays incurred when any one of a non-singleton set of volunteers have to do the next step (and everyone hopes someone else does it). The next ingredient was that we do not usually require a vote among all members (again, not easy with volunteers with limited bandwidth and occasional phases of absence). Instead, the shepherd makes a recommendation (accept/reject), and if the other committee members do not complain, this silence is taken as consent, and we come to a decision. It seems this idea can also be traced back on Richard, who suggested that once a decision is requested, the shepherd [generates] consensus. If consensus is elusive, then we vote. At the end of the year we agreed and wrote down these rules, created the mailing list for our internal, but publicly archived committee discussions, and began accepting proposals, starting with Adam Gundry s `OverloadedRecordFields`. At that point, there was no secretary role yet, so how I did become one? It seems that in February 2017 I started to clean-up and refine the process documentation, fixing bugs in the process (like requiring authors to set Github labels when they don t even have permissions to do that). This in particular meant that someone from the committee had to manually handle submissions and so on, and by the aforementioned principle that at every step there ought to be exactly one person in change, the role of a secretary followed naturally. In the email in which I described that role I wrote:
Simon already shoved me towards picking up the secretary hat, to reduce load on Ben.
So when I merged the updated process documentation, I already listed myself secretary . It wasn t just Simon s shoving that put my into the role, though. I dug out my original self-nomination email to Ben, and among other things I wrote:
I also hope that there is going to be clear responsibilities and a clear workflow among the committee. E.g. someone (possibly rotating), maybe called the secretary, who is in charge of having an initial look at proposals and then assigning it to a member who shepherds the proposal.
So it is hardly a surprise that I became secretary, when it was dear to my heart to have a smooth continuous process here. I am rather content with the result: These three ingredients single secretary, per-proposal shepherds, silence-is-consent helped the committee to be effective throughout its existence, even as every once in a while individual members dropped out.

Ulterior motivation I must admit, however, there was an ulterior motivation behind me grabbing the secretary role: Yes, I did want the committee to succeed, and I did want that authors receive timely, good and decisive feedback on their proposals but I did not really want to have to do that part. I am, in fact, a lousy proposal reviewer. I am too generous when reading proposals, and more likely mentally fill gaps in a specification rather than spotting them. Always optimistically assuming that the authors surely know what they are doing, rather than critically assessing the impact, the implementation cost and the interaction with other language features. And, maybe more importantly: why should I know which changes are good and which are not so good in the long run? Clearly, the authors cared enough about a proposal to put it forward, so there is some need and I do believe that Haskell should stay an evolving and innovating language but how does this help me decide about this or that particular feature. I even, during the formation of the committee, explicitly asked that we write down some guidance on Vision and Guideline ; do we want to foster change or innovation, or be selective gatekeepers? Should we accept features that are proven to be useful, or should we accept features so that they can prove to be useful? This discussion, however, did not lead to a concrete result, and the assessment of proposals relied on the sum of each member s personal preference, expertise and gut feeling. I am not saying that this was a mistake: It is hard to come up with a general guideline here, and even harder to find one that does justice to each individual proposal. So the secret motivation for me to grab the secretary post was that I could contribute without having to judge proposals. Being secretary allowed me to assign most proposals to others to shepherd, and only once in a while myself took care of a proposal, when it seemed to be very straight-forward. Sneaky, ain t it?

7 Years later For years to come I happily played secretary: When an author finished their proposal and public discussion ebbed down they would ping me on GitHub, I would pick a suitable shepherd among the committee and ask them to judge the proposal. Eventually, the committee would come to a conclusion, usually by implicit consent, sometimes by voting, and I d merge the pull request and update the metadata thereon. Every few months I d summarize the current state of affairs to the committee (what happened since the last update, which proposals are currently on our plate), and once per year gathered the data for Simon Peyton Jones annually GHC Status Report. Sometimes some members needed a nudge or two to act. Some would eventually step down, and I d sent around a call for nominations and when the nominations came in, distributed them off-list among the committee and tallied the votes. Initially, that was exciting. For a long while it was a pleasant and rewarding routine. Eventually, it became a mere chore. I noticed that I didn t quite care so much anymore about some of the discussion, and there was a decent amount of naval-gazing, meta-discussions and some wrangling about claims of authority that was probably useful and necessary, but wasn t particularly fun. I also began to notice weaknesses in the processes that I helped shape: We could really use some more automation for showing proposal statuses, notifying people when they have to act, and nudging them when they don t. The whole silence-is-assent approach is good for throughput, but not necessary great for quality, and maybe the committee members need to be pushed more firmly to engage with each proposal. Like GHC itself, the committee processes deserve continuous refinement and refactoring, and since I could not muster the motivation to change my now well-trod secretarial ways, it was time for me to step down. Luckily, Adam Gundry volunteered to take over, and that makes me feel much less bad for quitting. Thanks for that! And although I am for my day job now enjoying a language that has many of the things out of the box that for Haskell are still only language extensions or even just future proposals (dependent types, `BlockArguments`, `do` notation with `( foo)` expressions and Unicode), I m still around, hosting the Haskell Interlude Podcast, writing on this blog and hanging out at ZuriHac etc.

Valhalla's Things: A Corset or Two

a black coutil midbust corset, from a 3/4 front view, showing the busk closure, a waist tape and external boning channels made of the same twill tape and placed about 1-2 cm from each other at waist level.

CW for body size change mentions I needed a corset, badly. Years ago I had a chance to have my measurements taken by a former professional corset maker and then a lesson in how to draft an underbust corset, and that lead to me learning how nice wearing a well-fitted corset feels. Later I tried to extend that pattern up for a midbust corset, with success. And then my body changed suddenly, and I was no longer able to wear either of those, and after a while I started missing them. Since my body was still changing (if no longer drastically so), and I didn t want to use expensive materials for something that had a risk of not fitting after too little time, I decided to start by making myself a summer lightweight corset in aida cloth and plastic boning (for which I had already bought materials). It fitted, but not as well as the first two ones, and I ve worn it quite a bit. I still wanted back the feeling of wearing a comfy, heavy contraption of coutil and steel, however. After a lot of procrastination I redrafted a new pattern, scrapped everything, tried again, had my measurements taken by a dressmaker [#dressmaker], put them in the draft, cut a first mock-up in cheap cotton, fixed the position of a seam, did a second mock-up in denim [#jeans] from an old pair of jeans, and then cut into the cheap herringbone coutil I was planning to use. And that s when I went to see which one of the busks in my stash would work, and realized that I had used a wrong vertical measurement and the front of the corset was way too long for a midbust corset. a corset busk basted to a mock-up with scraps of fabric between each stud / loop.

a corset busk basted to a mock-up with scraps of fabric between each stud / loop.

Luckily I also had a few longer busks, I basted one to the denim mock up and tried to wear it for a few hours, to see if it was too long to be comfortable. It was just a bit, on the bottom, which could be easily fixed with the Power Tools¹. Except, the more I looked at it the more doing this felt wrong: what I needed most was a midbust corset, not an overbust one, which is what this was starting to be. I could have trimmed it down, but I knew that I also wanted this corset to be a wearable mockup for the pattern, to refine it and have it available for more corsets. And I still had more than half of the cheap coutil I was using, so I decided to redo the pattern and cut new panels. And this is where the or two comes in: I m not going to waste the overbust panels: I had been wanting to learn some techniques to make corsets with a fashion fabric layer, rather than just a single layer of coutil, and this looks like an excellent opportunity for that, together with a piece of purple silk that I know I have in the stash. This will happen later, however, first I m giving priority to the underbust. Anyway, a second set of panels was cut, all the seam lines marked with tailor tacks, and I started sewing by inserting the busk. And then realized that the pre-made boning channel tape I had was too narrow for the 10 mm spiral steel I had plenty of. And that the 25 mm twill tape was also too narrow for a double boning channel. On the other hand, the 18 mm twill tape I had used for the waist tape was good for a single channel, so I decided to put a single bone on each seam, and then add another piece of boning in the middle of each panel. Since I m making external channels, making them in self fabric would have probably looked better, but I no longer had enough fabric, because of the cutting mishap, and anyway this is going to be a strictly underwear only corset, so it s not a big deal. Once the boning channel situation was taken care of, everything else proceeded quite smoothly and I was able to finish the corset during the Christmas break, enlisting again my SO to take care of the flat steel boning while I cut the spiral steels myself with wire cutters. The same corset straight from the front: the left side is a few mm longer than the right side

The same corset straight from the front: the left side is a few mm longer than the right side

I could have been a bit more precise with the binding, as it doesn t align precisely at the front edge, but then again, it s underwear, nobody other than me and everybody who reads this post is going to see it and I was in a hurry to see it finished. I will be more careful with the next one. The same corset from the back, showing cross lacing with bunny ears at the waist and a lacing gap of about 8 cm.

The same corset from the back, showing cross lacing with bunny ears at the waist and a lacing gap of about 8 cm.

I also think that I haven t been careful enough when pressing the seams and applying the tape, and I ve lost about a cm of width per part, so I m using a lacing gap that is a bit wider than I planned for, but that may change as the corset gets worn, and is still within tolerance. Also, on the morning after I had finished the corset I woke up and realized that I had forgotten to add garter tabs at the bottom edge. I don t know whether I will ever use them, but I wanted the option, so maybe I ll try to add them later on, especially if I can do it without undoing the binding. The next step would have been flossing, which I proceeded to postpone until I ve worn the corset for a while: not because there is any reason for it, but because I still don t know how I want to do it :) What was left was finishing and uploading the pattern and instructions, that are now on my sewing pattern website as #FreeSoftWear, and finally I could post this on the blog.

i.e. by asking my SO to cut and sand it, because I m lazy and I hate doing that part :D

Michael Ablassmeier: Migrating a system to Hetzner cloud using REAR and kexec

I needed to migrate an existing system to an Hetzner cloud VPS. While it is possible to attach KVM consoles and custom ISO images to dedicated servers, i didn t find any way to do so with regular cloud instances. For system migrations i usually use REAR, which has never failed me. (and also has saved my ass during recovery multiple times). It s an awesome utility! It s possible to do this using the Hetzner recovery console too, but using REAR is very convenient here, because it handles things like re-creating the partition layout and network settings automatically! The steps are:

Create bootable REAR rescue image on the source system.
Register a target system in Hetzner Cloud with at least the same disk size as the source system.
Boot the REAR image s initrd and kernel from the running VPS system using kexec
Make the REAR recovery console accessible via SSH (or use Hetzners console).
Let REAR do its magic and re-partition the system.
Restore the system data to the freshly partitioned disks
Let REAR handle the bootloader and network re-configuration.

Example To create a rescue image on the source system:

apt install rear
echo OUTPUT=ISO > /etc/rear/local.conf
rear mkrescue -v
[..]
Wrote ISO image: /var/lib/rear/output/rear-debian12.iso (185M)

My source system had a 128 GB disk, so i registered an instance on Hetzner cloud with greater disk size to make things easier:

Now copy the ISO image to the newly created instance and extract its data:

 apt install kexec-tools
 scp rear-debian12.iso root@49.13.193.226:/tmp/
 modprobe loop
 mount -o loop rear-debian12.iso /mnt/

Reboot the running VPS instance into the REAR recovery image using somewhat the same kernel cmdline:

root@testme:~# cat /proc/cmdline

Now watch the system on the Console booting into the REAR system:

ip addr

$ ip route add default via 172.31.1.1

The network configuration might differ, the source system in this example used DHCP, as the target does. If REAR detects changed static network configuration it guides you through the setup pretty nicely. Login via SSH (REAR will store your ssh public keys in the image) and start the recovery process, follow the steps as suggested by REAR:

Bits from Debian: Statement about the EU Cyber Resilience Act

Debian Public Statement about the EU Cyber Resilience Act and the Product Liability Directive The European Union is currently preparing a regulation "on horizontal cybersecurity requirements for products with digital elements" known as the Cyber Resilience Act (CRA). It is currently in the final "trilogue" phase of the legislative process. The act includes a set of essential cybersecurity and vulnerability handling requirements for manufacturers. It will require products to be accompanied by information and instructions to the user. Manufacturers will need to perform risk assessments and produce technical documentation and, for critical components, have third-party audits conducted. Discovered security issues will have to be reported to European authorities within 25 hours (1). The CRA will be followed up by the Product Liability Directive (PLD) which will introduce compulsory liability for software. While a lot of these regulations seem reasonable, the Debian project believes that there are grave problems for Free Software projects attached to them. Therefore, the Debian project issues the following statement:

Free Software has always been a gift, freely given to society, to take and to use as seen fit, for whatever purpose. Free Software has proven to be an asset in our digital age and the proposed EU Cyber Resilience Act is going to be detrimental to it. a. As the Debian Social Contract states, our goal is "make the best system we can, so that free works will be widely distributed and used." Imposing requirements such as those proposed in the act makes it legally perilous for others to redistribute our work and endangers our commitment to "provide an integrated system of high-quality materials with no legal restrictions that would prevent such uses of the system". (2) b. Knowing whether software is commercial or not isn't feasible, neither in Debian nor in most free software projects - we don't track people's employment status or history, nor do we check who finances upstream projects (the original projects that we integrate in our operating system). c. If upstream projects stop making available their code for fear of being in the scope of CRA and its financial consequences, system security will actually get worse rather than better. d. Having to get legal advice before giving a gift to society will discourage many developers, especially those without a company or other organisation supporting them.
Debian is well known for its security track record through practices of responsible disclosure and coordination with upstream developers and other Free Software projects. We aim to live up to the commitment made in the Debian Social Contract: "We will not hide problems." (3) a.The Free Software community has developed a fine-tuned, tried-and-tested system of responsible disclosure in case of security issues which will be overturned by the mandatory reporting to European authorities within 24 hours (Art. 11 CRA). b. Debian spends a lot of volunteering time on security issues, provides quick security updates and works closely together with upstream projects and in coordination with other vendors. To protect its users, Debian regularly participates in limited embargos to coordinate fixes to security issues so that all other major Linux distributions can also have a complete fix when the vulnerability is disclosed. c. Security issue tracking and remediation is intentionally decentralized and distributed. The reporting of security issues to ENISA and the intended propagation to other authorities and national administrations would collect all software vulnerabilities in one place. This greatly increases the risk of leaking information about vulnerabilities to threat actors, representing a threat for all the users around the world, including European citizens. d. Activists use Debian (e.g. through derivatives such as Tails), among other reasons, to protect themselves from authoritarian governments; handing threat actors exploits they can use for oppression is against what Debian stands for. e. Developers and companies will downplay security issues because a "security" issue now comes with legal implications. Less clarity on what is truly a security issue will hurt users by leaving them vulnerable.
While proprietary software is developed behind closed doors, Free Software development is done in the open, transparent for everyone. To retain parity with proprietary software the open development process needs to be entirely exempt from CRA requirements, just as the development of software in private is. A "making available on the market" can only be considered after development is finished and the software is released.
Even if only "commercial activities" are in the scope of CRA, the Free Software community - and as a consequence, everybody - will lose a lot of small projects. CRA will force many small enterprises and most probably all self employed developers out of business because they simply cannot fulfill the requirements imposed by CRA. Debian and other Linux distributions depend on their work. If accepted as it is, CRA will undermine not only an established community but also a thriving market. CRA needs an exemption for small businesses and, at the very least, solo-entrepreneurs.

Information about the voting process: Debian uses the Condorcet method for voting. Simplistically, plain Condorcets method can be stated like so : "Consider all possible two-way races between candidates. The Condorcet winner, if there is one, is the one candidate who can beat each other candidate in a two-way race with that candidate." The problem is that in complex elections, there may well be a circular relationship in which A beats B, B beats C, and C beats A. Most of the variations on Condorcet use various means of resolving the tie. Debian's variation is spelled out in the constitution, specifically, A.5(3) Sources: (1) CRA proposals and links & PLD proposals and links (2) Debian Social Contract No. 2, 3, and 4 (3) Debian Constitution

Russ Allbery: Review: The Blackwing War

Review: The Blackwing War, by K.B. Spangler

Series:	Deep Witches #1
Publisher:	A Girl and Her Fed Books
Copyright:	March 2021
ISBN:	blackwing-war
Format:	Kindle
Pages:	284

The Blackwing War is the first book of a projected space opera series. I previously reviewed Stoneskin, which was intended as a prelude to this series. In theory you can start here, but I would read Stoneskin first. Tembi is a Witch, which means she can ask the Deep to do things for her. At the start of the book, those things mostly involve disarming bombs. The galaxy is in the middle of a genocidal war between the well-equipped and all-but-officially supported Sagittarius Armed Forces, also known as the Blackwings, and the Sabenta resistance movement. To settle the galaxy, humans fiddled with their genes to adapt themselves to otherwise-hostile planets. The Blackwings take exception, in the tradition of racist humans throughout history, and think it's time to purify human bloodlines again. Both sides are using bombs. The Deep is the brilliant idea of this series. It seems to exist everywhere simultaneously, it's alive, it adores teleporting things, and it's basically a giant cosmic puppy. Humans are nearly incomprehensible to the Deep, and it's nearly incomprehensible to humans, but it somehow picks out specific humans who can (sort of) understand it and whom it gets attached to and somehow makes immortal. These are the Witches, and they have turned the Deep into the logistical backbone of human civilization. Essentially all commerce and travel is now done through Deep teleportation, requested by a Witch and coordinated by Lancaster, the Witches' governing council. The exception is war. Lancaster is strictly neutral; it does not take sides, even in the face of an ongoing genocide, and it refuses to transport military ships, any type of weapons, or even war refugees. Domino, Lancaster's cynically manipulative leader, is determined to protect its special privileges and position at all costs. Tembi is one of the quasi-leaders of a resistance against that position, but even they are reluctant to ask the Deep to take sides in a war. To them, the Deep is a living magical creature that they are exploiting, and which also tends to be a bundle of nerves. Using it as a weapon feels like a step too far. That's how the situation lies at the start of this book when, after a successful bomb defusing, the Deep whisks Tembi away to watch an unknown weapon blow up a moon. A lot of this book consists of Tembi unraveling a couple of mysteries, starting with the apparent experimental bomb and then expanding to include the apparent drugging and disappearance of her former classmate. The low-grade war gets worse throughout, leaving Tembi torn between the justifications for Lancaster's neutrality and her strong sense of basic morality. The moments when Tembi gets angry enough or impatient enough to take action are the best parts, but a lot of this book is quite grim. Do not expect all to be resolved in a happy ending. There is some catharsis, but The Blackwing War is also clearly setup for a longer series. Tembi is a great character and the Deep is even better. I thoroughly enjoyed reading about both of them, and Tembi's relationship with the Deep is a delight. Usually I get frustrated by baffling incomprehensibility as a plot devices, but Spangler pulls it off as well as I've seen it done. But unfortunately, this book is firmly in the "gets worse before it will get better" part of the overall story arc, and the sequels have not yet appeared. The Blackwing War ends on a cliffhanger that portends huge changes for the characters and the setting, and if I had the next book to rush into, I wouldn't mind the grimness as much. As is, it was a somewhat depressing reading experience despite its charms, and despite a somewhat optimistic ending (that I doubt will truly resolve anything). I think the world-building elements were a touch predictable, and I wish Spangler wouldn't have her characters keep trying to justify Domino's creepy, abusive, and manipulative actions. But the characters are so much fun, and the idea of the Deep as a character is such a delight, that I am hooked on this series regardless. Recommended, although I will (hopefully) be able to recommend it more heartily once at least one sequel has been published. Content warnings: genocide, racism, violent death. Rating: 7 out of 10

Reproducible Builds: Reproducible Builds in November 2023

Welcome to the November 2023 report from the Reproducible Builds project! In these reports we outline the most important things that we have been up to over the past month. As a rather rapid recap, whilst anyone may inspect the source code of free software for malicious flaws, almost all software is distributed to end users as pre-compiled binaries (more).

Reproducible Builds Summit 2023 Between October 31st and November 2nd, we held our seventh Reproducible Builds Summit in Hamburg, Germany! Amazingly, the agenda and all notes from all sessions are all online many thanks to everyone who wrote notes from the sessions. As a followup on one idea, started at the summit, Alexander Couzens and Holger Levsen started work on a cache (or tailored front-end) for the snapshot.debian.org service. The general idea is that, when rebuilding Debian, you do not actually need the whole ~140TB of data from snapshot.debian.org; rather, only a very small subset of the packages are ever used for for building. It turns out, for `amd64`, `arm64`, `armhf`, `i386`, `ppc64el`, `riscv64` and `s390` for Debian trixie, unstable and experimental, this is only around 500GB ie. less than 1%. Although the new service not yet ready for usage, it has already provided a promising outlook in this regard. More information is available on https://rebuilder-snapshot.debian.net and we hope that this service becomes usable in the coming weeks. The adjacent picture shows a sticky note authored by Jan-Benedict Glaw at the summit in Hamburg, confirming Holger Levsen s theory that rebuilding all Debian packages needs a very small subset of packages, the text states that 69,200 packages (in Debian sid) list 24,850 packages in their `.buildinfo` files, in 8,0200 variations. This little piece of paper was the beginning of rebuilder-snapshot and is a direct outcome of the summit! The Reproducible Builds team would like to thank our event sponsors who include Mullvad VPN, openSUSE, Debian, Software Freedom Conservancy, Allotropia and Aspiration Tech.

Beyond Trusting FOSS presentation at SeaGL On November 4th, Vagrant Cascadian presented Beyond Trusting FOSS at SeaGL in Seattle, WA in the United States. Founded in 2013, SeaGL is a free, grassroots technical summit dedicated to spreading awareness and knowledge about free source software, hardware and culture. The summary of Vagrant s talk mentions that it will:
[ ] introduce the concepts of Reproducible Builds, including best practices for developing and releasing software, the tools available to help diagnose issues, and touch on progress towards solving decades-old deeply pervasive fundamental security issues Learn how to verify and demonstrate trust, rather than simply hoping everything is OK!
Germane to the contents of the talk, the slides for Vagrant s talk can be built reproducibly, resulting in a PDF with a SHA1 of `cfde2f8a0b7e6ec9b85377eeac0661d728b70f34` when built on Debian bookworm and `c21fab273232c550ce822c4b0d9988e6c49aa2c3` on Debian sid at the time of writing.

Human Factors in Software Supply Chain Security Marcel Fourn , Dominik Wermke, Sascha Fahl and Yasemin Acar have published an article in a Special Issue of the IEEE s Security & Privacy magazine. Entitled A Viewpoint on Human Factors in Software Supply Chain Security: A Research Agenda, the paper justifies the need for reproducible builds to reach developers and end-users specifically, and furthermore points out some under-researched topics that we have seen mentioned in interviews. An author pre-print of the article is available in PDF form.

Community updates On our mailing list this month:

Julien Lepiller mentioned that they were interested in translating our website, and provided offered GNU Guix s translation framework (Weblate) as a potential model to emulate.

Bernhard M. Wiedemann posted a positive LibreOffice success story documenting that, after some work:
[ ] today I hold in my hands the first two bit-identical LibreOffice rpm packages. And this is the success I wanted to share with you all today [and] it makes me feel as if we can solve anything.

kpcyrd reported on their excellent results with making `esp32c3` microcontroller firmware reproducible with Rust, repro-env and Arch Linux:
I chose the `esp32c3` [board] because it has good Rust support from the `esp-rs` project, and you can get a dev board for about 6-8 . To document my build environment I used `repro-env` together with Arch Linux because its archive is very reliable and contains all the different Rust development tools I needed.

Separate to their work on LibreOffice however, Bernhard M. Wiedemann also requested assistance with a number of packages that so far refuse to build reproducibly. He writes that the common theme around them is that they use scheme or lisp to produce binaries with a `dump` command and hopes that someone may be able to help.

Finally, Fay Stegerman regrettably reports that she will no longer be able to work on Android reproducible builds nor update the Reproducible Builds community with the status of reproducibility within F-Droid.

openSUSE updates Bernhard M. Wiedemann has created a wiki page outlining an proposal to create a general-purpose Linux distribution which consists of 100% bit-reproducible packages albeit minus the embedded signature within RPM files. It would be based on openSUSE Tumbleweed or, if available, its Slowroll-variant. In addition, Bernhard posted another monthly update for his work elsewhere in openSUSE.

Reproducibility-related changes in Debian As recently reported in the most recent Debian Developer News, Paul Gevers has integrated a package s reproducibility status into the way Debian migrates packages into the next stable release. For the `amd64`, `arm64`, `i386` and `armhf` architectures, data is collected from the Reproducible Builds testing framework is collected by this migration software even though, at the time of writing, it neither causes nor migration bonuses nor blocks migration. Indeed, the information only results are visible on Britney s excuses as well as on individual packages pages on tracker.debian.org.

Ubuntu Launchpad now supports `.buildinfo` files Back in 2017, Steve Langasek filed a bug against Ubuntu s Launchpad code hosting platform to report that `.changes` files (artifacts of building Ubuntu and Debian packages) reference `.buildinfo` files that aren t actually exposed by Launchpad itself. This was causing issues when attempting to process `.changes` files with tools such as Lintian. However, it was noticed last month that, in early August of this year, Simon Quigley had resolved this issue, and `.buildinfo` files are now available from the Launchpad system.

PHP reproducibility updates There have been two updates from the PHP programming language this month. Firstly, the widely-deployed PHPUnit framework for the PHP programming language have recently released version 10.5.0, which introduces the inclusion of a `composer.lock` file, ensuring total reproducibility of the shipped binary file. Further details and the discussion that went into their particular implementation can be found on the associated GitHub pull request. In addition, the presentation Leveraging Nix in the PHP ecosystem has been given in late October at the PHP International Conference in Munich by Pol Dellaiera. While the video replay is not yet available, the (reproducible) presentation slides and speaker notes are available.

diffoscope changes diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues. This month, Chris Lamb made a number of changes, including:

Improving DOS/MBR extraction by adding support for `7z`. [ ]

Adding a missing `RequiredToolNotFound` import. [ ]

As a UI/UX improvement, try and avoid printing an extended traceback if diffoscope runs out of memory. [ ]

Mark diffoscope as stable on PyPI.org. [ ]

Uploading version `252` to Debian unstable. [ ]

Website updates A huge number of notes were added to our website that were taken at our recent Reproducible Builds Summit held between October 31st and November 2nd in Hamburg, Germany. In particular, a big thanks to Arnout Engelen, Bernhard M. Wiedemann, Daan De Meyer, Evangelos Ribeiro Tzaras, Holger Levsen and Orhun Parmaks z. In addition to this, a number of other changes were made, including:

Chris Lamb migrated the website s homepage to a hero image [ ], improved the documentation related to `SOURCE_DATE_EPOCH` and CMake [ ], added iomart (ne Bytemark) and DigitalOcean to our sponsors page [ ] and dropped an unnecessary link on some horizontal navigation buttons [ ].

Holger Levsen also made a large number of notes pages from our 2022 summit in Venice [ ], migrated the website s syntax highlighter from [Pygments]https://pygments.org/() to Rouge [ ], fixed some grammar on our donate page [ ][ ][ ] and did a lot of updates to the Hamburg Summit s general information page [ ][ ].

Upstream patches The Reproducible Builds project detects, dissects and attempts to fix as many currently-unreproducible packages as possible. We endeavour to send all of our patches upstream where appropriate. This month, we wrote a large number of such patches, including:

Bernhard M. Wiedemann:

`amber-cli` (date-related issue)

Vagrant Cascadian:

#1055969 filed against `kuttypy`.

Reproducibility testing framework The Reproducible Builds project operates a comprehensive testing framework (available at tests.reproducible-builds.org) in order to check packages and other artifacts for reproducibility. In October, a number of changes were made by Holger Levsen:

Debian-related changes:

Track packages marked as `Priority: important` in a new package set. [ ][ ]

Stop scheduling packages that fail to build from source in bookworm [ ] and bullseye. [ ].

Add old releases dashboard link in web navigation. [ ]

Permit re-run of the `pool_buildinfos` script to be re-run for a specific year. [ ]

Grant jbglaw access to the `osuosl4` node [ ][ ] along with lynxis [ ].

Increase RAM on the `amd64` Ionos builders from 48 GiB to 64 GiB; thanks IONOS! [ ]

Move buster to archived suites. [ ][ ]

Reduce the number of `arm64` architecture workers from 24 to 16 in order to improve stability [ ], reduce the workers for `amd64` from 32 to 28 and, for `i386`, reduce from 12 down to 8 [ ].

Show the entire build history of each Debian package. [ ]

Stop scheduling already tested package/version combinations in Debian bookworm. [ ]

Snapshot service for rebuilders

Add an HTTP-based API endpoint. [ ][ ]

Add a Gunicorn instance to serve the HTTP API. [ ]

Add an NGINX config [ ][ ][ ][ ]

System-health:

Detect failures due to HTTP 503 Service Unavailable errors. [ ]

Detect failures to update package sets. [ ]

Detect unmet dependencies. (This usually occurs with builds of Debian `live-build`.) [ ]

Misc-related changes:

do install systemd-ommd on jenkins. [ ]

fix harmless typo in squid.conf for codethink04. [ ]

fixup: reproducible Debian: add gunicorn service to serve /api for rebuilder-snapshot.d.o. [ ]

Increase codethink04 s Squid `cache_dir` size setting to 16 GiB. [ ]

Don t install `systemd-oomd` as it unfortunately kills `sshd` [ ]

Use `debootstrap` from backports when commisioning nodes. [ ]

Add the `live_build_debian_stretch_gnome`, `debsums-tests_buster` and `debsums-tests_buster` jobs to the zombie list. [ ][ ]

Run `jekyll build` with the `--watch` argument when building the Reproducible Builds website. [ ]

Misc node maintenance. [ ][ ][ ]

Other changes were made as well, however, including Mattia Rizzolo fixing `rc.local` s Bash syntax so it can actually run [ ], commenting away some file cleanup code that is (potentially) deleting too much [ ] and fixing the `html_brekages` page for Debian package builds [ ]. Finally, diagnosed and submitted a patch to add a `AddEncoding gzip .gz` line to the tests.reproducible-builds.org Apache configuration so that Gzip files aren t re-compressed as Gzip which some clients can t deal with (as well as being a waste of time).

Michael Ablassmeier: Testing system updates using libvirts checkpoint feature

If you want to test upgrades on virtual machines (running on libvit/qemu/kvm) these are usually the most common steps:

Clone the virtual machine and test the upgrade.
Create a snapshot beforehand, do an in-place upgrade and hope everything works. If not, revert the snapshot..
Combine both methods
Use LVM or filesystem snapshots (snapper, etc)

As with recent versions, both libvirt and qemu have full support for dirty bitmaps (so called checkpoints). These checkpoints, once existent, will track changes to the block level layer and can be exported via NBD protocol. Usually one can create these checkpoints using virsh checkpoint-create[-as], with a proper xml description. Using the pull based model, the following is possible:

Issue an backup-begin statement and freeze the virtual machines file systems during this process (using qemu-agent) so you get an consistent system state.
Create an qcow2 image with backing image option that points to the created (readonly) NBD export via unix socket as overlay.
Use the created overlay image to boot up the instance and test the system upgrade.
Do so while the virtual machine is operating without any downtime.

The overlay image will only use the disk space for the blocks changed during upgrade: no need to create a full clone which may waste a lot of disk space. In order to simplify the first step, its possible to use virtnbdbackup for creating the required consistent checkpoint and export its data using a unix domain socket. Update: As alternative, ive just created a small utility called vircpt to create and export checkpoints. In my example im using a debian11 virtual machine with qemu guest agent configured:

# virsh list --all
 Id Name State 
 ------------------------------------------ 
 1 debian11_default running

Now let virtnbdbackup create an checkpoint, freeze the filesystems during creation and tell libvirt to provide us with a usable NBD server listening on an unix socket:

# virtnbdbackup -d debian11_default -o /tmp/foo -s
INFO lib common - printVersion [MainThread]: Version: 1.9.45 Arguments: ./virtnbdbackup -d debian11_default -o /tmp/foo -s
[..] 
INFO root virtnbdbackup - main [MainThread]: Local NBD Endpoint socket: [/var/tmp/virtnbdbackup.5727] 
INFO root virtnbdbackup - startBackupJob [MainThread]: Starting backup job.
INFO fs fs - freeze [MainThread]: Freezed [2] filesystems. 
INFO fs fs - thaw [MainThread]: Thawed [2] filesystems. 
INFO root virtnbdbackup - main [MainThread]: Started backup job for debugging, exiting.

We can now use nbdinfo to display some information about the NBD export:

# nbdinfo "nbd+unix:///vda?socket=/var/tmp/virtnbdbackup.5727" 
    protocol: newstyle-fixed without TLS, using structured packets 
    export="vda": 
    export-size: 137438953472 (128G) 
    content: 
        DOS/MBR boot sector uri: nbd+unix:///vda?socket=/var/tmp/virtnbdbackup.5727

And create a backing image that we can use to test an in-place upgrade:

# qemu-img create -F raw -b nbd+unix:///vda?socket=/var/tmp/virtnbdbackup.5727 -f qcow2 upgrade.qcow2

Now we have various ways for booting the image:

Create another domain config in libvirt which points to this disk image, boot.
Extract the current qemu command line for the the running domain using virsh domxml-to-native qemu-argv --domain debian11_default and execute it manually after adjusting required parameters.
Trust for everything to work out in the simplest way and simply boot up the image via:

# qemu-system-x86_64 -hda upgrade.qcow2 -m 2500 --enable-kvm

After performing the required tests within the virtual machine we can simply kill the active NBD backup job :

# virtnbdbackup -d debian11_default -o /tmp/foo -k
INFO lib common - printVersion [MainThread]: Version: 1.9.45 Arguments: ./virtnbdbackup -d debian11_default -o /tmp/foo -k 
[..]
INFO root virtnbdbackup - main [MainThread]: Stopping backup job

And remove the created qcow image:

Chilling Effect is a space opera, kind of; more on the genre classification in a moment. It is the first volume of a series, although it reaches a reasonable conclusion on its own. It was Valerie Valdes's first novel. Captain Eva Innocente's line of work used to be less than lawful, following in the footsteps of her father. She got out of that life and got her own crew and ship. Now, the La Sirena Negra and its crew do small transport jobs for just enough money to stay afloat. Or, maybe, a bit less than that, when the recipient of a crate full of psychic escape-artist cats goes bankrupt before she can deliver it and get paid. It's a marginal and tenuous life, but at least she isn't doing anything shady. Then the Fridge kidnaps her sister. The Fridge is a shadowy organization of extortionists whose modus operandi is to kidnap a family member of their target, stuff them in cryogenic suspension, and demand obedience lest the family member be sold off as indentured labor after a few decades as a popsicle. Eva will be given missions that she and her crew have to perform. If she performs them well, she will pay off the price of her sister's release. Eventually. Oh, and she's not allowed to tell anyone. I found it hard to place the subgenre of this novel more specifically than comedy-adventure. The technology fits space opera: there are psychic cats, pilots who treat ships as extensions of their own body, brain parasites, a random intergalactic warlord, and very few attempts to explain anything with scientific principles. However, the stakes aren't on the scale that space opera usually goes for. Eva and her crew aren't going to topple governments or form rebellions. They're just trying to survive in a galaxy full of abusive corporations, dodgy clients, and the occasional alien who requires you to carry extensive documentation to prove that you can't be hunted for meat. It is also, as you might guess from that description, occasionally funny. That part of the book didn't mesh for me. Eva is truly afraid for her sister, and some of the events in the book are quite sinister, but the antagonist is an organization called The Fridge that puts people in fridges. Sexual harassment in a bar turns into obsessive stalking by a crazed intergalactic warlord who frequently interrupts the plot by randomly blasting things with his fleet, which felt like something from Hitchhiker's Guide to the Galaxy. The stakes for Eva, and her frustrations at being dragged back into a life she escaped, felt too high for the wacky, comic descriptions of the problems she gets into. My biggest complaint, though, is that the plot is driven by people not telling other people critical information they should know. Eva is keeping major secrets from her crew for nearly the entire book. Other people are also keeping information from Eva. There is a romance subplot driven almost entirely by both parties refusing to talk to each other about the existence of a romance subplot. For some people, this is catnip, but it's one of my least favorite fictional tropes and I found much of the book both frustrating and stressful. Fictional characters keeping important secrets from each other apparently raises my blood pressure. One of the things I did like about this book is that Eva is Hispanic and speaks like it. She resorts to Spanish frequently for curses, untranslatable phrases, aphorisms, derogatory comments, and similar types of emotional communication that don't feel right in a second language. Most of the time one can figure out the meaning from context, but Valdes doesn't feel obligated to hold the reader's hand and explain everything. I liked that. I think this approach is more viable in these days of ebook readers that can attempt translations on demand, and I think it does a lot to make Eva feel like a real person. I think the characters are the best part of this book, once one gets past the frustration of their refusal to talk to each other. Eva and the alien ship engineer get the most screen time, but Pink, Eva's honest-to-a-fault friend, was probably my favorite character. I also really enjoyed Min, the ship pilot whose primary goal is to be able to jack into the ship and treat it as her body, and otherwise doesn't particularly care about the rest of the plot as long as she gets paid. A lot of books about ship crews like this one lean hard into found family. This one felt more like a group of coworkers, with varying degrees of friendship and level of interest in their shared endeavors, but without the too-common shorthand of making the less-engaged crew members either some type of villain or someone who needs to be drawn out and turned into a best friend or love interest. It's okay for a job to just be a job, even if it's one where you're around the same people all the time. People who work on actual ships do it all the time. This is a half-serious, half-comic action romp that turned out to not be my thing, but I can see why others will enjoy it. Be prepared for a whole lot of communication failures and an uneven emotional tone, but if you're looking for a space-ships-and-aliens story that doesn't take itself very seriously and has some vague YA vibes, this may work for you. Followed by Prime Deceptions, although I didn't like this well enough to read on. Rating: 6 out of 10

Shirish Agarwal: FSCKing /home

There is a bit of context that needs to be shared before I get to this and would be a long one. For reasons known and unknown, I have a lot of sudden electricity outages. Not just me, all those who are on my line. A discussion with a lineman revealed that around 200+ families and businesses are on the same line and when for whatever reason the electricity goes for all. Even some of the traffic lights don t work. This affects software more than hardware or in some cases, both. And more specifically HDD s are vulnerable. I had bought an APC unit several years for precisely this, but over period of time it just couldn t function and trips also when the electricity goes out. It s been 6-7 years so can t even ask customer service to fix the issue and from whatever discussions I have had with APC personnel, the only meaningful difference is to buy a new unit but even then not sure this is an issue that can be resolved, even with that. That comes to the issue that happens once in a while where the system fsck is unable to repair /home and you need to use an external pen drive for the same. This is my how my hdd stacks up
/ is on dev/sda7 /boot is on /dev/sda6, /boot/efi is on /dev/sda2 and /home is on /dev/sda8 so theoretically, if /home for some reason doesn t work I should be able drop down on /dev/sda7, unmount /dev/sda8, run fsck and carry on with my work. I tried it number of times but it didn t work. I was dropping down on tty1 and attempting the same, no dice as root/superuser getting the barest x-term. So first I tried asking couple of friends who live nearby me. Unfortunately, both are MS-Windows users and both use what are called as company-owned laptops . Surfing on those systems were a nightmare. Especially the number of pop-ups of ads that the web has become. And to think about how much harassment ublock origin has saved me over the years. One of the more interesting bits from both their devices were showing all and any downloads from fosshub was showing up as malware. I dunno how much of that is true or not as haven t had to use it as most software we get through debian archives or if needed, download from github or wherever and run/install it and you are in business. Some of them even get compiled into a good .deb package but that s outside the conversation atm. My only experience with fosshub was few years before the pandemic and that was good. I dunno if fosshub really has malware or malwarebytes was giving false positives. It also isn t easy to upload a 600 MB+ ISO file somewhere to see whether it really has malware or not. I used to know of a site or two where you could upload a suspicious file and almost 20-30 famous and known antivirus and anti-malware engines would check it and tell you the result. Unfortunately, I have forgotten the URL and seeing things from MS-Windows perspective, things have gotten way worse than before. So left with no choice, I turned to the local LUG for help. Fortunately, my mobile does have e-mail and I could use gmail to solicit help. While there could have been any number of live CD s that could have helped but one of my first experiences with GNU/Linux was that of Knoppix that I had got from Linux For You (now known as OSFY) sometime in 2003. IIRC, had read an interview of Mr. Klaus Knopper as well and was impressed by it. In those days, Debian wasn t accessible to non-technical users then and Knoppix was a good tool to see it. In fact, think he was the first to come up with the idea of a Live CD and run with it while Canonical/Ubuntu took another 2 years to do it. I think both the CD and the interview by distrowatch was shared by LFY in those early days. Of course, later the story changes after he got married, but I think that is more about Adriane rather than Knoppix. So Vishal Rao helped me out. I got an HP USB 3.2 32GB Type C OTG Flash Drive x5600c (Grey & Black) from a local hardware dealer around similar price point. The dealer is a big one and has almost 200+ people scattered around the city doing channel sales who in turn sell to end users. Asking one of the representatives about their opinion on stopping electronic imports (apparently more things were added later to the list including all sorts of sundry items from digital cameras to shavers and whatnot.) The gentleman replied that he hopes that it would not happen otherwise more than 90% would have to leave their jobs. They already have started into lighting fixtures (LED bulbs, tubelights etc.) but even those would come in the same ban

The main argument as have shared before is that Indian Govt. thinks we need our home grown CPU and while I have no issues with that, as shared before except for RISC-V there is no other space where India could look into doing that. Especially after the Chip Act, Biden has made that any new fabs or any new thing in chip fabrication will only be shared with Five Eyes only. Also, while India is looking to generate about 2000 GW by 2030 by solar, China has an ambitious 20,000 GW generation capacity by the end of this year and the Chinese are the ones who are actually driving down the module prices. The Chinese are also automating their factories as if there s no tomorrow. The end result of both is that China will continue to be the world s factory floor for the foreseeable future and whoever may try whatever policies, it probably is gonna be difficult to compete with them on prices of electronic products. That s the reason the U.S. has been trying so that China doesn t get the latest technology but that perhaps is a story for another day.

HP USB 3.2 Type C OTG Flash Drive x5600c For people who have had read this blog they know that most of the flash drives today are MLC Drives and do not have the longevity of the SLC Drives. For those who maybe are new, this short brochure/explainer from Kingston should enhance your understanding. SLC Drives are rare and expensive. There are also a huge number of counterfeit flash drives available in the market and almost all the companies efforts whether it s Kingston, HP or any other manufacturer, they have been like a drop in the bucket. Coming back to the topic at hand. While there are some tools that can help you to figure out whether a pen drive is genuine or not. While there are products that can tell you whether they are genuine or not (basically by probing the memory controller and the info. you get from that.) that probably is a discussion left for another day. It took me couple of days and finally I was able to find time to go Vishal s place. The journey of back and forth lasted almost 6 hours, with crazy traffic jams. Tells you why Pune or specifically the Swargate, Hadapsar patch really needs a Metro. While an in-principle nod has been given, it probably is more than 5-7 years or more before we actually have a functioning metro. Even the current route the Metro has was supposed to be done almost 5 years to the date and even the modified plan was of 3 years ago. And even now, most of the Stations still need a lot of work to be done. PMC, Deccan as examples etc. still have loads to be done. Even PMT (Pune Muncipal Transport) that that is supposed to do the last mile connections via its buses has been putting half-hearted attempts

Vishal Rao While Vishal had apparently seen me and perhaps we had also interacted, this was my first memory of him although we have been on a few boards now and then including stackexchange. He was genuine and warm and shared 4-5 distros with me, including Knoppix and System Rescue as shared by Arun Khan. While this is and was the first time I had heard about Ventoy apparently Vishal has been using it for couple of years now. It s a simple shell script that you need to download and run on your pen drive and then just dump all the .iso images. The easiest way to explain ventoy is that it looks and feels like Grub. Which also reminds me an interaction I had with Vishal on mobile. While troubleshooting the issue, I was unsure whether it was filesystem that was the issue or also systemd was corrupted. Vishal reminded me of putting fastboot to the kernel parameters to see if I m able to boot without fscking and get into userspace i.e. /home. Although journalctl and systemctl were responding even on tty1 still was a bit apprehensive. Using fastboot was able to mount the whole thing and get into userspace and that told me that it s only some of the inodes that need clearing and there probably are some orphaned inodes. While Vishal had got a mini-pc he uses that a server, downloads stuff to it and then downloads stuff from it. From both privacy, backup etc. it is a better way to do things but then you need to laptop to access it. I am sure he probably uses it for virtualization and other ways as well but we just didn t have time for that discussion. Also a mini-pc can set you back anywhere from 25 to 40k depending on the mini-pc and the RAM and the SSD. And you need either a lappy or an Raspberry Pi with some kinda visual display to interact with the mini-pc. While he did share some of the things, there probably could have been a far longer interaction just on that but probably best left for another day. Now at my end, the system I had bought is about 5-6 years old. At that time it only had 6 USB 2.0 drives and 2 USB 3.0 (A) drives.
The above image does tell of the various form factors. One of the other things is that I found the pendrive and its connectors to be extremely fiddly. It took me number of times fiddling around with it when I was finally able to put in and able to access the pen drive partitions. Unfortunately, was unable to see/use systemrescue but Knoppix booted up fine. I mounted the partitions briefly to see where is what and sure enough /dev/sda8 showed my /home files and folders. Unmounted it, then used $fsck -y /dev/sda8 and back in business. This concludes what happened. Updates Quite a bit was left out on the original post, part of which I didn t know and partly stuff which is interesting and perhaps need a blog post of their own. It s sad I won t be part of debconf otherwise who knows what else I would have come to know.

One of the interesting bits that I came to know about last week is the Alibaba T-Head T-Head TH1520 RISC-V CPU and saw it first being demoed on a laptop and then a standalone tablet. The laptop is an interesting proposition considering Alibaba opened up it s chip thing only couple of years ago. To have an SOC within 18 months and then under production for lappies and tablets is practically unheard of especially of a newbie/startup. Even AMD took 3-4 years for its first chip.It seems they (Alibaba) would be parceling them out by quarter end 2023 and another 1000 pieces/Units first quarter next year, while the scale is nothing compared to the behemoths, I think this would be more as a matter of getting feedback on both the hardware and software. The value proposition is much better than what most of us get, at least in India. For example, they are doing a warranty for 5 years and also giving spare parts. RISC-V has been having a lot of resurgence in China in part as its an open standard and partly development will be far cheaper and faster than trying x86 or x86-64. If you look into both the manufacturers, due to monopoly, both of them now give 5-8% increment per year, and if you look back in history, you would find that when more chips were in competition, they used to give 15-20% performance increment per year.

2. While Vishal did share with me what he used and the various ways he uses the mini-pc, I did have a fun speculating on what he could use it. As shared by Romane as his case has shared, the first thing to my mind was backups. Filesystems are notorious in the sense they can be corrupted or can be prone to be corrupted very easily as can be seen above . Backups certainly make a lot of sense, especially rsync. The other thing that came to my mind was having some sort of A.I. and chat server. IIRC, somebody has put quite a bit of open source public domain data in debian servers that could be used to run either a chatbot or an A.I. or both and use that similar to how chatGPT but with much limited scope than what chatgpt uses. I was also thinking a media server which Vishal did share he does. I may probably visit him sometime to see what choices he did and what he learned in the process, if anything. Another thing that could be done is just take a dump of any of commodity markets or any markets and have some sort of predictive A.I. or whatever. A whole bunch of people have scammed thousands of Indian users on this, but if you do it on your own and for your own purposes to aid you buy and sell stocks or whatever commodity you may fancy. After all, nowadays markets themselves are virtual. While Vishal s mini-pc doesn t have any graphics, if it was an AMD APU mini-pc, something like this he could have hosted games in the way of thick server, thin client where all graphics processing happens on the server rather than the client. With virtual reality I think the case for the same case could be made or much more. The only problem with VR/AR is that we don t really have mass-market googles, eye pieces or headset. The only notable project that Google has/had in that place is the Google VR Cardboard headset and the experience is not that great or at least was not that great few years back when I could hear and experience the same. Most of the VR headsets say for example the Meta Quest 2 is for around INR 44k/- while Quest 3 is INR 50k+ and officially not available. As have shared before, the holy grail of VR would be when it falls below INR 10k/- so it becomes just another accessory, not something you really have to save for. There also isn t much content on that but then that is also the whole chicken or egg situation. This again is a non-stop discussion as so much has been happening in that space it needs its own blog post/article whatever. Till later.

Shirish Agarwal: License Raj 2.0, 2023

About a week back Jio launched a laptop called JioBook that will be manufactured in China

The most interesting thing is that the whole thing will be produced in Hunan, China. Then 3 days later India mandates a licensing requirement for Apple, Dell and other laptop/tablet manufacturers. And all of these in the guise of Make in India . It is similar how India has exempted Adani and the Tatas from buying as much solar cells as are needed and then sell the same in India. Reliance will be basically monopolizing the laptop business. And if people think that projects like Raspberry Pi, Arduino etc. will be exempted they have another think coming.

History of License Raj After India became free, in the 1980s the Congress wanted to open its markets to the world just like China did. But at that time, the BJP, though small via Jan Sangh made the argument that we are not ready for the world. The indian businessman needs a bit more time. And hence a compromise was made. The compromise was simple. Indian Industry and people who wanted to get anything from the west, needed a license. This was very much in line how the Russian economy was evolving. All the three nations, India, China and Russia were on similar paths. China broke away where it opened up limited markets for competition and gave state support to its firms. Russia and Japan on the other hand, kept their markets relatively closed. The same thing happened in India, what happened in Russia and elsewhere. The businessman got what he wanted, he just corrupted the system. Reliance, the conglomerate today abused the same system as much as it could. Its defence was to be seen as the small guy. I wouldn t go into that as that itself would be a big story in itself. Whatever was sold in India was sold with huge commissions and just like Russia scarcity became the order of the day. Monopolies flourished and competition was nowhere. These remained till 1991 when Prime Minister Mr. Manmohan Singh was forced to liberalize and open up the markets. Even at that time, the RSS through its Swadeshi Jagran Manch was sharing the end of the world prophecies for the Indian businessman.

2014 Current Regime In 2010, in U.K. the Conservative party came in power under the leadership of David Cameron who was influenced by the policies of Margaret Thatcher who arguably ditched manufacturing in the UK. David Cameron and his party did the same 2010 onwards but for public services under the name austerity. India has been doing the same. The inequality has gone up while people s purchasing power has gone drastically down. CMIE figures are much more drastic and education is a joke.
Add to that since 2016 funding for scientists have gone to the dogs and now they are even playing with doctor s careers. I do not have to remind people that a woman scientist took almost a quarter century to find a drug delivery system that others said was impossible. And she did it using public finance. Science is hard. I have already shared in a previous blog post how it took the Chinese 20 years to reach where they are and somehow we think we will be able to both China and Japan. Of the 160 odd countries that are on planet earth, only a handful of countries have both the means and the knowledge to use and expand on that. While I was not part of Taiwan Debconf, later I came to know that even Taiwan in many ways is similar to Japan in the sense that a majority of its population is stuck in low-paid jobs (apart from those employed in TSMC) which is similar to Keiretsu or Chabeol from either Japan or South Korea. In all these cases, only a small percentage of the economy is going forward while the rest is stagnating or even going backwards. Similar is the case in India as well Unlike the Americans who chose the path to have more competition, we have chosen the path to have more monopolies. So even though, I very much liked Louis es project sooner or later finding the devices itself would be hard. While the recent notification is for laptops, what stops them from doing the same with mobiles or even desktop systems. As it is, both smartphones as well as desktop systems has been contracting since last year as food inflation has gone up. Add to that availability of products has been made scarce (whether by design or not, unknown.) The end result, the latest processor launched overseas becomes the new thing here 3-4 years later. And that was before this notification. This will only decrease competition and make Ambanis rich at cost of everyone else. So much for east of doing business . Also the backlash has been pretty much been tepid. So what I shared will probably happen again sooner or later. The only interesting thing is that it s based on Android, probably in part due to the issues people seeing in both Windows 10, 11 and whatnot. Till later. Update :- The print tried a decluttering but instead cluttered the topic. While what he shared all was true, and certainly it is a step backwards but he didn t need to show how most Indians had to go to RBI for the same. I remember my Mamaji doing the same and sharing afterwards that all he had was $100 for a day which while being a big sum was paltry if you were staying in a hotel and were there for company business. He survived on bananas and whatver cheap veg. he could find then. This is almost 35-40 odd years ago. As shared the Govt. has been doing missteps for quite sometime now. The print does try to take a balanced take so it doesn t run counter of the Government but even it knows that this is a bad take. The whole thing about security is just laughable, did they wake up after 9 years. And now in its own wisdom it apparently has shifted the ban instead from now to 3 months afterwards. Of course, most people on the right just applauding without understanding the complexities and implications of the same. Vendors like Samsung and Apple who have made assembly operations would do a double-think and shift to Taiwan, Vietnam, Mexico anywhere. Global money follows global trends. And such missteps do not help

Implications in A.I. products One of the things that has not been thought about how companies that are making A.I. products in India or even MNC s will suffer. Most of them right now are in stealth mode but are made for Intel or AMD or ARM depending upon how it works for them. There is nothing to tell if the companies made their plea and was it heard or unheard. If the Government doesn t revert it then sooner or later they would either have to go abroad or cash out/sell to somebody else. Some people on the right also know this but for whatever reason have chosen to remain silent. Till later

Shirish Agarwal: Birth Control, Consent, Rape & Violence.

Consent, Violence, Sexual Abuse This again would be somewhat of a mature post. So children, please refrain from reading. When I hear the above words, my first thought goes to Aamir Khan s Season 1 Episode 2 in Satyamev Jayate. This was the first time that the topic of child sexual abuse was bought in the forefront in the hall rather than a topic to be discussed in the corner. Unfortunately, that episode is still in Hindi and no English subtitles available even today shows a lack of sensitivity in Indian s part to still come to terms with Child abuse that happens in India. The numbers that they had shared at that time were shocking. More than 50 per cent children experience sexual abuse and mostly from friends or relatives. That means 1 in every 2 children. And this was in 2012. But the problem of child sexual abuse didn t start then, it started in the 1960 s, 70 s. In the 1960 s, 1970s we didn t have much of cinema and TV and whatever there was pretty limited. There were few B movie producers, but most of them came into their own in the 1980s. So what influenced Indians in those days were softcore magazines that either had a mature aunt or a teen and they would tease and sooner or later the man would sort of overpower them and fulfill his needs. Even mainstream Indian cinema used similar tropes. One of the most memorable songs of that era Wada Karo Nahi Chodoge Tum Meera Saath from Aa Gale Lag jaa. A bit of context for the song. This is where Shashi Kapoor sees, he tries to ask her to date him, she says no. He tries to put an act where he shows he can t skate or rather pretends. And kinda takes a promise from her that she will date him if he is able to skate. And viola, the next moment he is not just skating, but dancing and singing as well. And the whole he touches her and you can see that is uncomfortable and yet after a while he woos her. Now this is problematic today because we are seeing it from today s lens. It might also have problematic with the feminists of that time, but they probably would have been called overly sensitive or something like that. And this is what went in Universal cinema. But this is just tip of the surface. There were and are multiple poems and even art in those times that flirted and even sort of engaged with sexual molestation, rape both in poems as well as literature, both in Hindi and various regional literature. Similar to stuff that Keats and some other poets (problematic stuff) they wrote and where both men and women were in two minds, whether to take all the other good literature out or kinda make the difference between the art and artist. Now, while Aamir spoke about consent it wasn t in any official capacity or even a legal capacity. The interesting thing was that there was an Act that kinda put some safeguards but had been doing rounds for almost a decade. Because the extremists on both sides, Hindus and Muslims were not in favor of that Act, it was still doing rounds. Aamir s episode on 6th May 2012 and the discussions in mainstream media following that forced the Indian legislature to make POSCO as a law on 22nd May 2012. Almost 6 months to 2 weeks, Nirbhaya happened and changes to the law happened in another 6 months. Both voyeurism and stalking were made jailable offenses and consent became part of lingua franca in the Supreme Court. Couple of weeks back, I had shared in the Manipur case the part about fingering . In the same Act, another change that was done that insertion of any part including foreign objects in any of the openings would be classed as rape . So in that Manipur case, at least those 2-3 people who have been identified as clear perpetrators according to the law of land would be rapists and should have the highest punishment. Unfortunately, the system is rigged against women as Vrinda Grover had shared just couple of weeks back. How a 6 month fast track case (to be completed within 6 months) becomes a 10 year old case tells you the efficacy of the system. The reality is far more worse than is shared or known. Just a few months ago, GOI shared some data on Sexual Harassment in 2018-19. And this is after constant pressurizing by Activists that GOI doesn t like. In fact, in 2021, Unicef had shared data about how India was one of the five countries where child brides are still prevalent. India denied but didn t produce any alternative data. The firing of Mr. James over NHFS data sets doesn t give it any brownie points to the present Government. What has happened in the last few years is that the Government for reasons of its own had been scrubbing and censoring a lot of data. I won t go far, just 2 day old story which I had shared just couple of days back. Roughly a 25 year old RPF constable kills his superior and kills 3 Muslims after going to various coaches and then the Government uses the defence of temporary insanity.
Even the mental instability defence has twists and turns
Incidentally, Press Trust of India is s private organization and not the public broadcaster of the old. And incidentally, just a few days back, it came to light that they hadn t paid Income tax for last 2-3 years. Because of issues in reward money, the public came to know otherwise they wouldn t have known. Coming back to the topic itself, there was a video where you could hear and see the accused stating after killing the three Muslims that if you want to remain in India, then you have to vote for only Modi or Yogi, otherwise this will happen. That video was scrubbed both from Twitter as well as YouTube. All centralized platforms at the very least, whether it is Google (Youtube) or Twitter or Meta uses its own media ID. Meta s being most problematic but that probably being a discussion for another day. The same censorship tools are applied rigorously and lot of incidents are buried. Cases of girls being thrown in lakes just after lakes or low numbers of conviction in case of gang rapes are more often than not disappears.
The above article shared just a few days ago that how low the conviction rates of gang rapes are in Gujarat tells you the story. You might get the story today, but wait for a few weeks and you will find that the story has disappeared. What most people do not know or understand is that the web is increasingly a public repository of idea, imaginations and trust and authoritarian regimes like Government of India is increasingly using both official as well as unofficial methods to suppress the same. To see that in the last 9 odd years, GOI has made the highest number of takedown requests and been either number one or number two tells all. My question is where we do from here ??? If even the Minister and her Ministry can do only whataboutery rather than answer the questions, then how we are supposed to come up solutions. And even if a solution exists, without the state and Center agreeing and co-operating with civil society, any solution will be far off the desired result. I am sorry that I at least have no answers

Reproducible Builds: Supporter spotlight: Simon Butler on business adoption of Reproducible Builds

The Reproducible Builds project relies on several projects, supporters and sponsors for financial support, but they are also valued as ambassadors who spread the word about our project and the work that we do. This is the seventh instalment in a series featuring the projects, companies and individuals who support the Reproducible Builds project. We started this series by featuring the Civil Infrastructure Platform project, and followed this up with a post about the Ford Foundation as well as recent ones about ARDC, the Google Open Source Security Team (GOSST), Bootstrappable Builds, the F-Droid project and David A. Wheeler. Today, however, we will be talking with Simon Butler, an associate senior lecturer in the School of Informatics at the University of Sk vde, where he undertakes research in software engineering that focuses on IoT and open source software, and contributes to the teaching of computer science to undergraduates.

Chris: For those who have not heard of it before, can you tell us more about the School of Informatics at Sk vde University? Simon: Certainly, but I may be a little long-winded. Sk vde is a city in the area between the two large lakes in southern Sweden. The city is a busy place. Sk vde is home to the regional hospital, some of Volvo s manufacturing facilities, two regiments of the Swedish defence force, a lot of businesses in the Swedish computer games industry, other tech companies and more.

The University of Sk vde is relatively small. Sweden s large land area and low population density mean that regional centres such as Sk vde are important and local universities support businesses by training new staff and supporting innovation. The School of Informatics has two divisions. One focuses on teaching and researching computer games. The other division encompasses a wider range of teaching and research, including computer science, web development, computer security, network administration, data science and so on.

Chris: You recently had a open-access paper published in Software Quality Journal. Could you tell us a little bit more about it and perhaps briefly summarise its key findings? Simon: The paper is one output of a collaborative research project with six Swedish businesses that use open source software. There are two parts to the paper. The first consists of an analysis of what the group of businesses in the project know about Reproducible Builds (R-Bs), their experiences with R-Bs and their perception of the value of R-Bs to the businesses. The second part is an interview study with business practitioners and others with experience and expertise in R-Bs. We set out to try to understand the extent to which software-intensive businesses were aware of R-Bs, the technical and business reasons they were or were not using R-Bs and to document the business and technical use cases for R-Bs. The key findings were that businesses are aware of R-Bs, and some are using R-Bs as part of their day-to-day development process. Some of the uses for R-Bs we found were not previously documented. We also found that businesses understood the value R-Bs have as part of engineering and software quality processes. They are also aware of the costs of implementing R-Bs and that R-Bs are an intangible value proposition - in other words, businesses can add value through process improvement by using R-Bs. But, that, currently at least, R-Bs are not a selling point for software or products.
Chris: You performed a large number of interviews in order to prepare your paper. What was the most surprising response to you? Simon: Most surprising is a good question. Everybody I spoke to brought something new to my understanding of R-Bs, and many responses surprised me. The interviewees that surprised me most were I01 and I02 (interviews were anonymised and interviewees were assigned numeric identities). I02 described the sceptical perspective that there is a viable, pragmatic alternative to R-Bs - verifiable builds - which I was aware of before undertaking the research. The company had developed a sufficiently robust system for their needs and worked well. With a large archive of software used in production, they couldn t justify the cost of retrofitting a different solution that might only offer small advantages over the existing system. Doesn t really sound too surprising, but the interview was one of the first I did on this topic, and I was very focused on the value of, and need for, trust in a system that motivated the R-B. The solution used by the company requires trust, but they seem to have established sufficient trust for their needs by securing their build systems to the extent that they are more or less tamper-proof. The other big surprise for me was I01 s use of R-Bs to support the verification of system configuration in a system with multiple embedded components at boot time. It s such an obvious application of R-Bs, and exactly the kind of response I hoped to get from interviewees. However, it is another instance of a solution where trust is only one factor. In the first instance, the developer is using R-Bs to establish trust in the toolchain. There is also the second application that the developer can use a set of R-Bs to establish that deployed system consists of compatible components. While this might not sound too significant, there appear to be some important potential applications. One that came to mind immediately is a problem with firmware updates on nodes in IoT systems where the node needs to update quickly with limited downtime and without failure. The node also needs to be able to roll back any update proposed by a server if there are conflicts with the current configuration or if any tests on the node fail. Perhaps the chances of failure could be reduced, if a node can instead negotiate with a server to determine a safe path to migrate from its current configuration to a working configuration with the upgraded components the central system requires? Another potential application appears to be in the configuration management of AI systems, where decisions need to be explainable. A means of specifying validated configurations of training data, models and deployed systems might, perhaps, be leveraged to prevent invalid or broken configurations from being deployed in production.
Chris: One of your findings was that reproducible builds were perceived to be good engineering practice . To what extent do you believe cultural forces affect the adoption or rejection of a given technology or practice? Simon: To a large extent. People s decisions are informed by cultural norms, and business decisions are made by people acting collectively. Of course, decision-making, including assessments of risk and usefulness, is mediated by individual positions on the continuum from conformity to non-conformity, as well as individual and in-group norms. Whether a business will consider a given technology for adoption will depend on cultural forces. The decision to adopt may well be made on the grounds of cost and benefits.
Chris: Another conclusion implied by your research is that businesses are often dealing with software deployment lifespans (eg. 20+ years) that differ from widely from those of the typical hobbyist programmer. To what degree do you think this temporal mismatch is a problem for both groups? Simon: This is a fascinating question. Long-term software maintenance is a requirement in some industries because of the working lifespans of the products and legal requirements to maintain the products for a fixed period. For some other industries, it is less of a problem. Consequently, I would tend to divide developers into those who have been exposed to long-term maintenance problems and those who have not. Although, more professional than hobbyist developers will have been exposed to the problem. Nonetheless, there are areas, such as music software, where there are also long-term maintenance challenges for data formats and software.
Chris: Based on your research, what would you say are the biggest blockers for the adoption of reproducible builds within business ? And, based on this, would you have any advice or recommendations for the broader reproducible builds ecosystem? Simon: From the research, the main blocker appears to be cost. Not an absolute cost, but there is an overhead to introducing R-Bs. Businesses (and thus business managers) need to understand the business case for R-Bs.

Making decision-makers in businesses aware of R-Bs and that they are valuable will take time. Advocacy at multiple levels appears to be the way forward and this is being done. I would recommend being persistent while being patient and to keep talking about reproducible builds. The work done in Linux distributions raises awareness of R-Bs amongst developers. Guix, NixOS and Software Heritage are all providing practical solutions and getting attention - I ve been seeing progressively more mentions of all three during the last couple of years. Increased awareness amongst developers should lead to more interest within companies. There is also research money being assigned to supply chain security and R-B s. The CHAINS project at KTH in Stockholm is one example of a strategic research project. There may be others that I m not aware of. The policy-level advocacy is slowly getting results in some countries, and where CISA leads, others may follow.
Chris: Was there a particular reason you alighted on the question of the adoption of reproducible builds in business? Do you think there s any truth behind the shopworn stereotype of hacker types neglecting the resources that business might be able to offer? Simon: Much of the motivation for the research came from the contrast between the visibility of R-Bs in open source projects and the relative invisibility of R-Bs in industry. Where companies are known to be using R-Bs (e.g. Google, etc.) there is no fuss, no hype. They were not selling R-Bs as a solution; instead the documentation is very matter-of-fact that R-Bs are part of a customer-facing process in their cloud solutions. An obvious question for me was that if some people use R-B s in software development, why doesn t everybody? There are limits to the tooling for some programming languages that mean R-Bs are difficult or impossible. But where creating an R-B is practical, why are they not used more widely? So, to your second question. There is another factor, which seems to be more about a lack of communication rather than neglecting opportunities. Businesses may not always be willing to discuss their development processes and innovations. Though I do think the increasing number of conferences (big and small) for software practitioners is helping to facilitate more communication and greater exchange of ideas.
Chris: Has your personal view of reproducible builds changed since before you embarked on writing this paper? Simon: Absolutely! In the early stages of the research, I was interested in questions of trust and how R-Bs were applied to resolve build and supply chain security problems. As the research developed, however, I started to see there were benefits to the use of R-Bs that were less obvious and that, in some cases, an R-B can have more than a single application.
Chris: Finally, do you have any plans to do future research touching on reproducible builds? Simon: Yes, definitely. There are a set of problems that interest me. One already mentioned is the use of reproducible builds with AI systems. Interpretable or explainable AI (XAI) is a necessity, and I think that R-Bs can be used to support traceability in the configuration and testing of both deployed systems and systems used during model training and evaluation. I would also like to return to a problem discussed briefly in the article, which is to develop a deeper understanding of the elements involved in the application of R-Bs that can be used to support reasoning about existing and potential applications of R-Bs. For example, R-Bs can be used to establish trust for different groups of individuals at different times, say, between remote developers prior to the release of software and by users after release. One question is whether when an R-B is used might be a significant factor. Another group of questions concerns the ways in which trust (of some sort) propagates among users of an R-B. There is an example in the paper of a company that rebuilds Debian reproducibly for security reasons and is then able to collaborate on software projects where software is built reproducibly with other companies that use public distributions of Debian.

Chris: Many thanks for this interview, Simon. If someone wanted to get in touch or learn more about you and your colleagues at the School of Informatics, where might they go? Thank you for the opportunity. It has been a pleasure to reflect a little more widely on the research! Personally, you can find out about my work on my official homepage and on my personal site. The software systems research group (SSRG) has a website, and the University of Sk vde s English language pages are also available. Chris: Many thanks for this interview, Simon!

Russell Coker: Links July 2023

Phys.org has an interesting article about finding evidence for nanohertz gravity waves [1]. 1nano-Herz is a wavelength of 31.7 light years! Wired has an interesting story about OpenAI saying that no further advances will be made with larger training models [2]. Bruce Schneier and Nathan Sanders wrote an insightful article about the need for government run GPT type systems [3]. He focuses on the US, but having other countries/groups of countries do it would be good too. We could have a Chinese one, an EU one, etc. I don t think it would necessarily make sense for a small country like Australia to have one but it would make a lot more sense than having nuclear submarines (which are much more expensive). The Roadmap project is a guide for learning new technologies [4]. The content seems quite good. Bigthink has an informative and darkly amusing article Horror stories of cryonics: The gruesome fates of futurists hoping for immortality [5]. From this month in Australia psilocybin (active ingredient in Magic Mushrooms) can be prescribed for depression and MDMA (known as Ecstacy on the streets) can be prescribed for PTSD [6]. That s great news! Slate has an interesting article about the Operation Underground Railroad organisation that purports to help sex trafficed chilren [7]. This is noteworthy now with the controverst over the recent movie about that. Apparently they didn t provide much help for kids after they had been rescued and at least some of the kids were trafficed specifically to fulfill the demand that they created by offering to pay for it. Vigilantes aren t as effective as law enforcement. The ACCC is going to prevent Apple and Google from forcing app developers to give them a share of in-app purchases in Australia [8]. We need this in every country! This site has links to open source versions of proprietary games [9]. Vice has an interesting article about the Hungarian neuroscientist Viktor T th who taught rats to play Doom 2 [10]. The next logical step is to have mini tanks that they can use in real battlefields. Like the Mason s Rats episode of Love Death and Robots on Netflix. Brian Krebs wrote a mind boggling pair of blog posts about the Ashley Adison hack [11]. A Jewish disgruntled ex-employee sending anti-semitic harassment to the Jewish CEO and maybe cooperating with anti-semitic organisations to harass him is one of the people involved, but he killed himself (due to mental health problems) before the hack took place. Long Now has an insightful blog post about digital avatars being used after the death of the people they are based on [12]. Tavis Ormandy s description of the zenbleed bug is interesting [13]. The technique for finding the bug is interesting as well as the information on how the internals of the CPUs in question work. I don t think this means AMD is bad, trying to deliver increasing performance while limited by the laws of physics is difficult and mistakes are sometimes made. Let s hope the microcode updates are well distributed. The Hacktivist documentary about Andrew Bunnie Huang is really good [14]. Bunnie s lecture about supply chain attacks is worth watching [15]. Most descriptions of this issue don t give nearly as much information. However bad you thought this problem was, after you watch this lecture you will realise it s worse than that!

Michael Ablassmeier: Java timezone sheanigans

While running CI tests for a application that is implemented in C and Java, some configuration scripts set the current timezone. The C implemented parts catch the change just nicely, but the java related parts still report the default image timezone. A simple example:

import java.util.*;
import java.text.*;
class simpleTest
 
        public static void main(String args[])
         
           Calendar cal = Calendar.getInstance();
           System.out.println("TIME ZONE :"+ cal.getTimeZone().getDisplayName());

Result:

vagrant@vm:~$ sudo timedatectl set-timezone America/Aruba 
vagrant@vm:~$ timedatectl 
[..]
                Time zone: America/Aruba (AST, -0400)
[..]
vagrant@vm:~$ java test.java
TIME ZONE :Central European Standard Time
vagrant@vm:~$ ls -alh /etc/localtime 
lrwxrwxrwx 1 root root 35 Jul 10 14:41 /etc/localtime -> ../usr/share/zoneinfo/America/Aruba

It appears the Java implementation uses /etc/timezone as source, not /etc/localtime.

vagrant@vm:~$ echo America/Aruba   sudo tee /etc/timezone 
America/Aruba
vagrant@vm:~$ java test.java
TIME ZONE :Atlantic Standard Time

dpkg-reconfigure tzdata updates this file as well, so using timedatectl only won t be enough (at least not on Debian based systems which run java based applications.)

Shirish Agarwal: Ayisha, Manju Warrier, Debutsav, Books

Ayisha After a long time I saw a movie that I enjoyed wholeheartedly. And it unexpectedly touched my heart. The name of the movie is Ayisha. The first frame of the movie itself sets the pace where we see Ayisha (Manju Warrier) who decides to help out a gang as lot of women were being hassled. So she agrees to hoodwink cops and help launder some money. Then she is shown to work as a maid for an elite Arab family. To portray a Muslim character in these polarized times really shows guts especially when the othering of the Muslim has been happening 24 7. In fact, just few days back I was shocked to learn that Muslim homes were being marked as Jews homes had been marked in the 1930 s. Not just homes but also businesses too. And after few days in a total hypocritical fashion one of the judges says that you cannot push people to buy or not buy from a shop. This is after systemically doing the whole hate campaign for almost 2 weeks. What value the judge s statements are after 2 weeks ??? The poison has already seeped in But I m drifting from the topic/movie.

The real fun of the movie is the beautiful relationship that happens between Ayisha and Mama, she is the biggest maternal figure in the house and in fact, her command is what goes in the house. The house or palace which is the perfect description is shown as being opulent but not as rich as both Mama and Ayisha are, spiritually and emotionally both giving and sharing of each other. Almost a mother daughter relationship, although with others she is shown as having a bit of an iron hand. Halfway through the movie we come to know that Ayisha was also a dramatist and an actress having worked in early Malayalam movies. I do not want to go through all the ups and downs as that is the beauty of the movie and it needs to be seen for that aspect. I am always sort of in two worlds where should I promote a book or series or movie or not because most of the time it is the unexpected that works. When we have expectation it doesn t. Avatar, the Way of the Water is an exception, not many movies I can recall like that where I had expectations and still the movie surpassed it. So maybe go with no expectations at all

Manju Warrier Manju Warrier should actually be called Manju Warrior as she chose to be with the survivor rather than the sexism that is prevalent in the Malayalam film industry which actually is more or less a mirror of Bollywood and society as whole. These three links should give enough background knowledge as to what has been happening although I m sure my Malayalam friends would more than add to that knowledge whatever may be missing. In quite a few movies, the women are making inroads without significant male strength. Especially Manju s movies have no male lead for the last few movies. Whether that is deliberate part on Manju or an obstacle being put in front of her. Anyone knows that having a male lead and a female lead enriches the value of a movie quite a bit. This doesn t mean one is better than the other but having both enriches the end product, as simple as that. This is sadly not happening. Having POSH training and having an ICC is something that each organization should look forward for. It s kind of mandatory need of hour, especially when we have young people all around us. I am hopeful that people who are from Kerala would shed some more background light on what has been happening.

Books I haven t yet submitted an application for Debconf. But my idea is irrespective of whether or not I m there, I do hope we can have a library where people can donate books and people can take away books as well. A kind of circular marketplace/library where just somebody notes what books are available. Even if 100 odd people are coming to Debconf that easily means 100 books of various languages. That in itself would be interesting and to see what people are reading, wanting to discuss etc. We could even have readings. IIRC, in 2016 we had a children s area, maybe we could do some readings from some books to children which fuels their imagination. Even people like me who are deaf would be willing to look at excerpts and be charmed by them. For instance, in all my forays of fantasy literature except for Babylon Steel I haven t read one book that has a female lead character and I have read probably around 100 odd fantasy books till date. Not a lot but still to my mind, is a big gap as far as literature is concerned. How would more women write fantasy if they don t have heroes to look forward to :(. Or maybe I may be missing some authors and characters that others know and I do not. Do others feel the same or this question hasn t even been asked ??? Dunno. Please let me know.

Debutsav So apparently Debutsav is happening 2 days from now. While I did come to know about it few days back I had to think whether I want to apply for this or apply for Debconf as I physically, emotionally can t do justice to both even though they are a few months apart. I wish all the best for the attendees as well as presenters sharing all the projects and hopefully somebody shares at least some of the projects that are presented there so we may know what new projects or softwares to follow or whatever. Till later.

Russell Coker: PinePhonePro First Impression

Hardware I received my PinePhone Pro [1] on Thursday, it seems in many ways better than the Purism Librem 5 [2] that I have previously written about. The PinePhone is thinner, lighter, and yet has a much longer battery life. A friend described the Librem5 as the CyberTruck phone and not in a good way. In a test I had my PinePhone and my Librem5 fully charged, left them for 4.5 hours without doing anything much with them, and then the PinePhone was at 85% and the Librem5 was at 57%. So the Librem5 will run out of battery after about 10 hours of not being used while a PinePhonePro can be expected to last about 30 hours. The PinePhonePro isn t as good as some of the recent Android phones in this regard but it shows the potential to be quite usable. For this test both phones were connected to a 2.4GHz Wifi network (which uses less power than 5GHz) and doing nothing much with an out of the box configuration. A phone that is checking email, social networking, and a couple of IM services will use the battery faster. But even if the PinePhone has it s battery used twice as fast in a more realistic test that will still be usable. Here are the passmark results from the PinePhone Pro [3] which got a CPU score of 888 compared to 507 for the Librem 5 and 678 for one of the slower laptops I ve used. The results are excluded from the Passmark averages because they identified the CPU as only having 4 cores (expecting just 4*A72) while the PinePhonePro has 6 cores (2*A72+4*A53). This phone definitely has the CPU power for convergence [4]! Default OS By default the PinePhone has a KDE based GUI and the Librem5 has a GNOME based GUI. I don t like any iteration of GNOME (I have tried them all and disliked them all) and I like KDE so I will tend to like anything that is KDE based more than anything GNOME based. But in addition to that the PinePhone has an interface that looks a lot like Android with the three on-screen buttons at the bottom of the display and the way it has the slide up tray for installed apps. Android is the most popular phone OS and looking like the most common option is often a good idea for a new and different product, this seems like an objective criteria to determine that the default GUI on the PinePhone is a better choice (at least for the default). When I first booted it and connected it to Wifi the updates app said that there were 633 updates to apply, but never applied them (I tried clicking on the update button but to no avail) and didn t give any error message. For me not being Debian is enough reason to dislike Manjaro, but if that wasn t enough then the failure to update would be a good start. When I ran pacman in a terminal window it said that each package was corrupt and asked if I wanted to delete it. According to tar tvJf the packages weren t corrupt. After downloading them again it said that they were corrupt again so it seemed that pacman wasn t working correctly. When the screen is locked and a call comes in it gives a window with Accept and Reject buttons but neither of them works. The default country code for Spacebar (the SMS app) is +1 (US) even though I specified Australia on the initial login. It also doesn t get the APN unlike Android phones which seem to have some sort of list of APNs. Upgrading to Debian The Debian Wiki page about Installing on the PinePhone Pro has the basic information [5]. The first thing it covers is installing the TOW boot loader which is already installed by default in recent PinePhones (such as mine). You can recognise that TOW is installed by pressing the volume-up button in the early stages of boot up (described as before and during the second vibration ), then the LED will turn blue and the phone will act as a USB mass storage device which makes it easy to do other install/recovery tasks. The other TOW option is to press volume-down to boot from a MicroSD card (the default is to boot the OS on the eMMC). The images linked from the Debian wiki page are designed to be installed with bmaptool from the bmap-tools Debian package. After installing that package and downloading the pre-built Mobian image I installed it with the command bmaptool copy mobian-pinephonepro-phosh-bookworm-12.0-rc3.img.gz /dev/sdb where /dev/sdb is the device that the USB mapped PinePhone storage was located. That took 6 minutes and then I rebooted my PinePhone into Mobian! Unfortunately the default GUI for Mobian is GNOME/Phosh. Changing it to KDE is my next task.

Michael Ablassmeier: updating to bookworm

Just updated to bookworm. Only thing that gave me headaches was OpenVPN refusing to accept the password/username combination specified via auth-user-pass option.. Mystery was solved by adding providers legacy default to the configuration file used.

Next.
