Louis-Philippe V ronneau: Montreal's Debian & Stuff - "September" 2023

Last Sunday, our local Debian user group gathered to chat, to work on Debian and to do other, non-Debian related hacking. A "Debian & Stuff"! It had been a while since we held a proper meetup. Our last event was the Montreal BSP we organised back in March 2023... We somewhat missed the window for a June meetup and summer events never seem to gather a good crowd, so I didn't try to organise one. All this to say it was nice to see folks from the Montreal Debian community :) This event was also the first time we were hosted by L'Espace des possibles - Petite Patrie, a social venue that aims to provide a space for not-for-profit activities, like repair caf s, sowing classes, board game nights, etc. It was really nice and we will surely meet there again in the future. A group picture during the event Many people came to the event, including some new ones. Although people always tend to come and go during the day, a total of 12 people attended the event. As always, people worked on very different projects! One of the focus of this D&S was assembling AirGradient DIY basic kits. Our local community has been talking a lot about air quality metrics in the past few months1. Tiago thus decided to have a company print the PCBs for this kit and graciously gave away a few spares. Michael then took upon himself to order parts on AliExpress and a few of us ended up soldering the kits together while chatting. An AirGradient DIY basic kit, semi-assembled Otherwise, some Debian work was also done: The whole event was super fun, the tacos we had for lunch were delicious (and very authentic!), and we ended up at a local microbrewery to share a pint later in the evening. Looking forward to the next event!
  1. Mostly as a result of the large forest fires in Canada this summer. I myself blogged twice about air quality-related projects recently.

Scarlett Gately Moore: KDE: KDE Neon updates! Qt6 transition moving along.

With user edition out the door last week, this week was spent stabilizing unstable! Spent some time sorting out our Calamares installer being quite grumpy which is now fixed by reverting an upstream change. Unstable and developer ISO rebuilt and installable. Spent some time sorting out some issues with using an unreleased appstream ( thanks ximion for help with packagekit! ) KDE applications are starting to switch to Qt6 in master this week, the big one being KDE PIM! This entails an enormous amount of work re-packaging. I have made a dent, sorta. To be continued next week. I fixed our signond / kaccounts line for qt6 which entailed some work on upstream code that uses QStringList.toSet which was removed in Qt6! Always learning new things! I have spent some time working on the KF6 content snap, working with Jarred to make sure his qt6 content snap will work for us. Unfortunately, I do not have much time for this as I must make money to survive, donations help free up time for this Our new proposal with Kevin s super awesome management company has been submitted and we will hopefully hear back next week. Thanks for stopping by! Till next week. If you can spare some change, consider a donation Thank you! https://gofund.me/b8b69e54

Dirk Eddelbuettel: RcppInt64 0.0.3 on CRAN: Now with nanotime Support

The still new package RcppInt64 (announced two weeks ago in this post, with this followup last week) arrived on CRAN earlier today in its second update and relase 0.0.3. RcppInt64 collects some of the previous conversions between 64-bit integer values in R and C++, and regroups them in a single package by providing a single header. It offers two interfaces: both a more standard as<>() converter from R values along with its companions wrap() to return to R, as well as more dedicated functions from and to . This release adds support for the corresponding nanotime conversion between R and C++. nanotime is leveraging the same bit64-based reprensentation of 64-bit integers for nanosecond resolution timestamps. A thorough S4 wrapping the offers R based access for convenient and powerful operations at nanosecond resolution. And as tweeted (here and here), tooted (here and here), and skeeted (here and here) in a quick preview last Sunday, it makes for easy and expressive code. The brief NEWS entry follows:

Changes in version 0.0.3 (2023-09-19)
  • The as<>() and wrap() converters are now declared inline.
  • Conversion to and from nanotime has been added.

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

Bits from Debian: DebConf23 closes in Kochi and DebConf24 announced

DebConf23 group photo - click to enlarge On Sunday 17 September 2023, the annual Debian Developers and Contributors Conference came to a close. Over 474 attendees representing 35 countries from around the world came together for a combined 89 events made up of Talks, Discussons, Birds of a Feather (BoF) gatherings, workshops, and activities in support of furthering our distribution, learning from our mentors and peers, building our community, and having a bit of fun. The conference was preceded by the annual DebCamp hacking session held September 3d through September 9th where Debian Developers and Contributors convened to focus on their Individual Debian related projects or work in team sprints geared toward in-person collaboration in developing Debian. In particular this year Sprints took place to advance development in Mobian/Debian, Reproducible Builds, and Python in Debian. This year also featured a BootCamp that was held for newcomers staged by a team of dedicated mentors who shared hands-on experience in Debian and offered a deeper understanding of how to work in and contribute to the community. The actual Debian Developers Conference started on Sunday 10 September 2023. In addition to the traditional 'Bits from the DPL' talk, the continuous key-signing party, lightning talks and the announcement of next year's DebConf4, there were several update sessions shared by internal projects and teams. Many of the hosted discussion sessions were presented by our technical teams who highlighted the work and focus of the Long Term Support (LTS), Android tools, Debian Derivatives, Debian Installer, Debian Image, and the Debian Science teams. The Python, Perl, and Ruby programming language teams also shared updates on their work and efforts. Two of the larger local Debian communities, Debian Brasil and Debian India shared how their respective collaborations in Debian moved the project forward and how they attracted new members and opportunities both in Debian, F/OSS, and the sciences with their HowTos of demonstrated community engagement. The schedule was updated each day with planned and ad-hoc activities introduced by attendees over the course of the conference. Several activities that were unable to be held in past years due to the Global COVID-19 Pandemic were celebrated as they returned to the conference's schedule: a job fair, the open-mic and poetry night, the traditional Cheese and Wine party, the group photos and the Day Trips. For those who were not able to attend, most of the talks and sessions were videoed for live room streams with the recorded videos to be made available later through the Debian meetings archive website. Almost all of the sessions facilitated remote participation via IRC messaging apps or online collaborative text documents which allowed remote attendees to 'be in the room' to ask questions or share comments with the speaker or assembled audience. DebConf23 saw over 4.3 TiB of data streamed, 55 hours of scheduled talks, 23 network access points, 11 network switches, 75 kb of equipment imported, 400 meters of gaffer tape used, 1,463 viewed streaming hours, 461 T-shirts, 35 country Geoip viewers, 5 day trips, and an average of 169 meals planned per day. All of these events, activies, conversations, and streams coupled with our love, interest, and participation in Debian annd F/OSS certainly made this conference an overall success both here in Kochi, India and On-line around the world. The DebConf23 website will remain active for archival purposes and will continue to offer links to the presentations and videos of talks and events. Next year, DebConf24 will be held in Haifa, Israel. As tradition follows before the next DebConf the local organizers in Israel will start the conference activites with DebCamp with particular focus on individual and team work towards improving the distribution. DebConf is committed to a safe and welcome environment for all participants. See the web page about the Code of Conduct in DebConf23 website for more details on this. Debian thanks the commitment of numerous sponsors to support DebConf23, particularly our Platinum Sponsors: Infomaniak, Proxmox, and Siemens. We also wish to thank our Video and Infrastructure teams, the DebConf23 and DebConf commitiees, our host nation of India, and each and every person who helped contribute to this event and to Debian overall.

Jo Shields: Building a NAS

The status quo Back in 2015, I bought an off-the-shelf NAS, a QNAP TS-453mini, to act as my file store and Plex server. I had previously owned a Synology box, and whilst I liked the Synology OS and experience, the hardware was underwhelming. I loaded up the successor QNAP with four 5TB drives in RAID10, and moved all my files over (after some initial DoA drive issues were handled).

That thing has been in service for about 8 years now, and it s been a mixed bag. It was definitely more powerful than the predecessor system, but it was clear that QNAP s OS was not up to the same standard as Synology s perhaps best exemplified by HappyGet 2 , the QNAP webapp for downloading videos from streaming services like YouTube, whose icon is a straight rip-off of StarCraft 2. On its own, meaningless but a bad omen for overall software quality

Additionally, the embedded Celeron processor in the NAS turned out to be an issue for some cases. It turns out, when playing back videos with subtitles, most Plex clients do not support subtitles properly instead they rely on the Plex server doing JIT transcoding to bake the subtitles directly into the video stream. I discovered this with some Blu-Ray rips of Game of Thrones some episodes would play back fine on my smart TV, but episodes with subtitled Dothraki speech would play at only 2 or 3 frames per second. The final straw was a ransomware attack, which went through all my data and locked every file below a 60MiB threshold. Practically all my music gone. A substantial collection of downloaded files, all gone. Some of these files had been carried around since my college days digital rarities, or at least digital detritus I felt a real sense of loss at having to replace. This episode was caused by a ransomware targeting specific vulnerabilities in the QNAP OS, not an error on my part. So, I decided to start planning a replacement with:
  • A non-garbage OS, whilst still being a NAS-appliance type offering (not an off-the-shelf Linux server distro)
  • Full remote management capabilities
  • A small form factor comparable to off-the-shelf NAS
  • A powerful modern CPU capable of transcoding high resolution video
  • All flash storage, no spinning rust
At the time, no consumer NAS offered everything (The Asustor FS6712X exists now, but didn t when this project started), so I opted to go for a full DIY rather than an appliance not the first time I ve jumped between appliances and DIY for home storage.

Selecting the core of the system There aren t many companies which will sell you a small motherboard with IPMI. Supermicro is a bust, so is Tyan. But ASRock Rack, the server division of third-tier motherboard vendor ASRock, delivers. Most of their boards aren t actually compliant Mini-ITX size, they re a proprietary Deep Mini-ITX with the regular screw holes, but 40mm of extra length (and a commensurately small list of compatible cases). But, thankfully, they do have a tiny selection of boards without the extra size, and I stumbled onto the X570D4I-2T, a board with an AMD AM4 socket and the mature X570 chipset. This board can use any AMD Ryzen chip (before the latest-gen Ryzen 7000 series); has built in dual 10 gigabit ethernet; IPMI; four (laptop-sized) RAM slots with full ECC support; one M.2 slot for NVMe SSD storage; a PCIe 16x slot (generally for graphics cards, but we live in a world of possibilities); and up to 8 SATA drives OR a couple more NVMe SSDs. It s astonishingly well featured, just a shame it costs about $450 compared to a good consumer-grade Mini ITX AM4 board costing less than half that. I was so impressed with the offering, in fact, that I crowed about it on Mastodon and ended up securing ASRock another sale, with someone else looking into a very similar project to mine around the same timespan. The next question was the CPU. An important feature of a system expected to run 24/7 is low power, and AM4 chips can consume as much as 130W under load, out of the box. At the other end, some models can require as little as 35W under load the OEM-only GE suffix chips, which are readily found for import on eBay. In their PRO variant, they also support ECC (all non-G Ryzen chips support ECC, but only Pro G chips do). The top of the range 8 core Ryzen 7 PRO 5750GE is prohibitively expensive, but the slightly weaker 6 core Ryzen 5 PRO 5650GE was affordable, and one arrived quickly from Hong Kong. Supplemented with a couple of cheap 16 GiB SODIMM sticks of DDR4 PC-3200 direct from Micron for under $50 a piece, that left only cooling as an unsolved problem to get a bootable test system. The official support list for the X570D4I-2T only includes two rackmount coolers, both expensive and hard to source. The reason for such a small list is the non standard cooling layout of the board instead of an AM4 hole pattern with the standard plastic AM4 retaining clips, it has an Intel 115x hole pattern with a non-standard backplate (Intel 115x boards have no backplate, the stock Intel 115x cooler attaches to the holes with push pins). As such every single cooler compatibility list excludes this motherboard. However, the backplate is only secured with a mild glue with minimal pressure and a plastic prying tool it can be removed, giving compatibility with any 115x cooler (which is basically any CPU cooler for more than a decade). I picked an oversized low profile Thermalright AXP120-X67 hoping that its 120mm fan would cool the nearby MOSFETs and X570 chipset too.

Testing up to this point Using a spare ATX power supply, I had enough of a system built to explore the IPMI and UEFI instances, and run MemTest86 to validate my progress. The memory test ran without a hitch and confirmed the ECC was working, although it also showed that the memory was only running at 2933 MT/s instead of the rated 3200 MT/s (a limit imposed by the motherboard, as higher speeds are considered overclocking). The IPMI interface isn t the best I ve ever used by a long shot, but it s minimum viable and allowed me to configure the basics and boot from media entirely via a Web browser.

One sad discovery, however, which I ve never seen documented before, on PCIe bifurcation. With PCI Express, you have a number of lanes which are allocated in groups by the motherboard and CPU manufacturer. For Ryzen prior to Ryzen 7000, that s 16 lanes in one slot for the graphics card; 4 lanes in one M.2 connector for an SSD; then 4 lanes connecting the CPU to the chipset, which can offer whatever it likes for peripherals or extra lanes (bottlenecked by that shared 4x link to the CPU, if it comes down to it). It s possible, with motherboard and CPU support, to split PCIe groups up for example an 8x slot could be split into two 4x slots (eg allowing two NVMe drives in an adapter card NVME drives these days all use 4x). However with a Cezanne Ryzen with integrated graphics, the 16x graphics card slot cannot be split into four 4x slots (ie used for for NVMe drives) the most bifurcation it allows is 8x4x4x, which is useless in a NAS.
Screenshot of PCIe 16x slot bifurcation options in UEFI settings, taken from IPMI remote control window
As such, I had to abandon any ideas of an all-NVMe NAS I was considering: the 16x slot split into four 4x, combined with two 4x connectors fed by the X570 chipset, to a total of 6 NVMe drives. 7.6TB U.2 enterprise disks are remarkably affordable (cheaper than consumer SATA 8TB drives), but alas, I was locked out by my 5650GE. Thankfully I found out before spending hundreds on a U.2 hot swap bay. The NVMe setup would be nearly 10x as fast as SATA SSDs, but at least the SATA SSD route would still outperform any spinning rust choice on the market (including the fastest 10K RPM SAS drives)

Containing the core The next step was to pick a case and power supply. A lot of NAS cases require an SFX (rather than ATX) size supply, so I ordered a modular SX500 unit from Silverstone. Even if I ended up with a case requiring ATX, it s easy to turn an SFX power supply into ATX, and the worst result is you have less space taken up in your case, hardly the worst problem to have. That said, on to picking a case. There s only one brand with any cachet making ITX NAS cases, Silverstone. They have three choices in an appropriate size: CS01-HS, CS280, and DS380. The problem is, these cases are all badly designed garbage. Take the CS280 as an example, the case with the most space for a CPU cooler. Here s how close together the hotswap bay (right) and power supply (left) are:
Internal image of Silverstone CS280 NAS build. Image stolen from ServeTheHome
With actual cables connected, the cable clearance problem is even worse:
Internal image of Silverstone CS280 NAS build. Image stolen from ServeTheHome
Remember, this is the best of the three cases for internal layout, the one with the least restriction on CPU cooler height. And it s garbage! Total hot garbage! I decided therefore to completely skip the NAS case market, and instead purchase a 5.25 -to-2.5 hot swap bay adapter from Icy Dock, and put it in an ITX gamer case with a 5.25 bay. This is no longer a served market 5.25 bays are extinct since nobody uses CD/DVD drives anymore. The ones on the market are really new old stock from 2014-2017: The Fractal Design Core 500, Cooler Master Elite 130, and Silverstone SUGO 14. Of the three, the Fractal is the best rated so I opted to get that one however it seems the global supply of new old stock fully dried up in the two weeks between me making a decision and placing an order leaving only the Silverstone case. Icy Dock have a selection of 8-bay 2.5 SATA 5.25 hot swap chassis choices in their ToughArmor MB998 series. I opted for the ToughArmor MB998IP-B, to reduce cable clutter it requires only two SFF-8611-to-SF-8643 cables from the motherboard to serve all eight bays, which should make airflow less of a mess. The X570D4I-2T doesn t have any SATA ports on board, instead it has two SFF-8611 OCuLink ports, each supporting 4 PCI Express lanes OR 4 SATA connectors via a breakout cable. I had hoped to get the ToughArmor MB118VP-B and run six U.2 drives, but as I said, the PCIe bifurcation issue with Ryzen G chips meant I wouldn t be able to run all six bays successfully.

Actual storage for the storage server My concept for the system always involved a fast boot/cache drive in the motherboard s M.2 slot, non-redundant (just backups of the config if the worst were to happen) and separate storage drives somewhere between 3.8 and 8 TB each (somewhere from $200-$350). As a boot drive, I selected the Intel Optane SSD P1600X 58G, available for under $35 and rated for 228 years between failures (or 11,000 complete drive rewrite cycles). So, on to the big expensive choice: storage drives. I narrowed it down to two contenders: new-old-stock Intel D3-S4510 3.84TB enterprise drives, at about $200, or Samsung 870 QVO 8TB consumer drives, at about $375. I did spend a long time agonizing over the specification differences, the ZFS usage reports, the expected lifetime endurance figures, but in reality, it came down to price $1600 of expensive drives vs $3200 of even more expensive drives. That s 27TB of usable capacity in RAID-Z1, or 23TB in RAID-Z2. For comparison, I m using about 5TB of the old NAS, so that s a LOT of overhead for expansion.

Booting up Bringing it all together is the OS. I wanted an appliance NAS OS rather than self-administering a Linux distribution, and after looking into the surrounding ecosystems, decided on TrueNAS Scale (the beta of the 2023 release, based on Debian 12).
TrueNAS Dashboard screenshot in browser window
I set up RAID-Z1, and with zero tuning (other than enabling auto-TRIM), got the following performance numbers:
IOPSBandwidth
4k random writes19.3k75.6 MiB/s
4k random reads36.1k141 MiB/s
Sequential writes 2300 MiB/s
Sequential reads 3800 MiB/s
Results using fio parameters suggested by Huawei
And for comparison, the maximum theoretical numbers quoted by Intel for a single drive:
IOPSBandwidth
4k random writes16k?
4k random reads90k?
Sequential writes 280 MiB/s
Sequential reads 560 MiB/s
Numbers quoted by Intel SSD successors Solidigm.
Finally, the numbers reported on the old NAS with four 7200 RPM hard disks in RAID 10:
IOPSBandwidth
4k random writes4301.7 MiB/s
4k random reads800632 MiB/s
Sequential writes 311 MiB/s
Sequential reads 566 MiB/s
Performance seems pretty OK. There s always going to be an overhead to RAID. I ll settle for the 45x improvement on random writes vs. its predecessor, and 4.5x improvement on random reads. The sequential write numbers are gonna be impacted by the size of the ZFS cache (50% of RAM, so 16 GiB), but the rest should be a reasonable indication of true performance. It took me a little while to fully understand the TrueNAS permissions model, but I finally got Plex configured to access data from the same place as my SMB shares, which have anonymous read-only access or authenticated write access for myself and my wife, working fine via both Linux and Windows. And that s it! I built a NAS. I intend to add some fans and more RAM, but that s the build. Total spent: about $3000, which sounds like an unreasonable amount, but it s actually less than a comparable Synology DiskStation DS1823xs+ which has 4 cores instead of 6, first-generation AMD Zen instead of Zen 3, 8 GiB RAM instead of 32 GiB, no hardware-accelerated video transcoding, etc. And it would have been a whole lot less fun!

Scarlett Gately Moore: KDE: Weekly report and News, 23.08.0 Snaps call for testing!

Another busy week in the KDE snap world. Most of the release-service apps are in candidate channel waiting to be tested. Testing is the bottle neck in the process, so I am trying something new and calling for help! Please test your favorite apps and report on https://discuss.kde.org/t/all-things-snaps-questions-concerns-praise/ any issues and which apps tested. Thanks! There are some very big fixes in this release: The KF6 content pack is coming along nicely using qt-framework-sdk snap! Qt5 content snap using KDE patch set is nearly complete! I believe I have a solution for our PIM applications by creating an Akondai dbus provider snap and setting all the PIM applications as consumers. I am waiting for manual review to pass. I have a pile of new applications waiting for reserved name approvals. Igor has pinged the relevant people to speed this normally quick process up. The pushback on per repository snapcraft files has stopped, so I have begun the process, which will take some time. This is a huge step in automating snap builds and cutting down my manual work so I can do more exciting things like plasma snaps! Some big news on my project, a big thank you goes out to Kevin Ottens for reaching out, his company does exactly what I need to move it forward. I will update as we hash out the details, but it looks like my project isn t dead after all! I know many have asked Why haven t you given up already?? The answer in short, I am stubborn. I refuse to give up on anything until I am given a good reason to. When I started my path in computers oh so many years ago, you would be surprised how many people told me to give it up, you ll never make it as a woman. Challenge accepted. Here I am, still going strong. When I want something, I go get it, no matter what it takes! I still need to have a ( somewhat desperate ) call for donations. This will hopefully end soon, but for now, please consider donating to my September survival fund! Please share with anyone you that may find my work useful in any way. Thanks for your consideration
PS: Debian uploads for bubble-gum are moving along. Please if you have any packaging you need done in Debian proper, let me know and I will get on it, time allowing of course.

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.
  1. 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.

Andrew Cater: 20230826 OMGWTFBBQ - Cambridge is waking up

The meat has been fetched: those of us in the house are about to get bacon sandwiches. Pepper the dog is in the garden. Time for the mayhem to start, I think.
Various folk are travelling here so it will soon be crowded: the weather is sunny but cool and it looks good for a three day weekend.

This is a huge effort that falls to Steve and Jo and a huge disruption for them each year - for which many thanks, as ever. [And, as is traditional on this blog, the posts only ever seem to appear from Cambridge].

Ian Jackson: I cycled to all the villages in alphabetical order

This last weekend I completed a bike rides project I started during the first Covid lockdown in 2020: I ve cycled to every settlement (and radio observatory) within 20km of my house, in alphabetical order. Stir crazy In early 2020, during the first lockdown, I was going a bit stir crazy. Clare said you re going very strange, you have to go out and get some exercise . After a bit of discussion, we came up with this plan: I d visit all the local villages, in alphabetical order. Choosing the radius I decided that I would pick a round number of kilometers, as the crow flies, from my house. 20km seemed about right. 25km would have included Ely, which would have been nice, but it would have added a great many places, all of them quite distant. Software I wrote a short Rust program to process OSM data into a list of places to visit, and their distances and bearings. You can download a tarball of the alphabetical villages scanner. (I haven t published the git history because it has my house s GPS coordinates in it, and because I committed the output files from which that location can be derived.) The Rides I set off on my first ride, to Aldreth, on Sunday the 31st of May 2020. The final ride collected Yelling, on Saturday the 19th of August 2023. I did quite a few rides in June and July 2020 - more than one a week. (I d read the lockdown rules, and although some of the government messaging said you should stay near your house, that wasn t in the legislation. Of course I didn t go into any buildings or anything.) I m not much of a morning person, so I often set off after lunch. For the longer rides I would usually pack a picnic. Almost all of the rides I did just by myself. There were a handful where I had friends along: Dry Drayton, which I collected with Clare, at night. I held my bike up so the light shone at the village sign, so we could take a photo of it. Madingley, Melbourn and Meldreth, which was quite an expedition with my friend Ben. We went out as far as Royston and nearby Barley (both outside my radius and not on my list) mostly just so that my project would have visited Hertfordshire. The Hemingfords, where I had my friend Matthew along, and we had a very nice pub lunch. Girton and Wilburton, where I visited friends. Indeed, I stopped off in Wilburton on one or two other occasions. And, of course, Yelling, for which there were four of us, again with a nice lunch (in Eltisley). I had relatively little mechanical trouble. My worst ride for this was Exning: I got three punctures that day. Luckily the last one was close to home. I often would stop to take lots of photos en-route. My mum in particular appreciated all the pretty pictures. Rules I decided on these rules: I would cycle to each destination, in order, and it would count as collected if I rode both there and back. I allowed collecting multiple villages in the same outing, provided I did them in the right order. (And obviously I was allowed to pass through places out of order, without counting them.) I tried to get a picture of the village sign, where there was one. Failing that, I got a picture of something in the village with the village s name on it. I think the only one I didn t manage this for was Westley Bottom; I had to make do with the word Westley on some railway level crossing equipment. In Barway I had to make do with a planning application, stuck to a pole. I tried not to enter and leave a village by the same road, if possible. Edge cases I had to make some decisions: I decided that I would consider the project complete if I visited everywhere whose centre was within my radius. But the centre of a settlement is rather hard to define. I needed a hard criterion for my OpenStreetMap data mining: a place counted if there was any node, way or relation, with the relevant place tag, any part of which was within my ambit. That included some places that probably oughtn t to have counted, but, fine. I also decided that I wouldn t visit suburbs of Cambridge, separately from Cambridge itself. I don t consider them separate settlements, at least, not if they re conurbated with Cambridge. So that excluded Trumpington, for example. But I decided that Girton and Fen Ditton were (just) separable. Although the place where I consider Girton and Cambridge to nearly touch, is administratively well inside Girton, I chose to look at land use (on the ground, and in OSM data), rather than administrative boundaries. But I did visit both Histon and Impington, and all each of the Shelfords and Stapleford, as separate entries in my list. Mostly because otherwise I d have to decide whether to skip (say) Impington, or Histon. Whereas skipping suburbs of Cambridge in favour of Cambridge itself was an easy decision, and it also got rid of a bunch of what would have been quite short, boring, urban expeditions. I sorted all the Greats and Littles under G and L, rather than (say) Shelford, Great , which seemed like it would be cheating because then I would be able to do Shelford, Great and Shelford, Little in one go. Northstowe turned from mostly a building site into something that was arguably a settlement, during my project. It wasn t included in the output of my original data mining. Of course it s conurbated with Oakington - but happily, Northstowe inserts right before Oakington in the alphabetical list, so I decided to add it, visiting both the old and new in the same day. There are a bunch of other minor edge cases. Some villages have an outlying hamlet. Mostly I included these. There are some individual farms, which I generally didn t count. Some stats I visited 150 villages plus the Lords Bridge radio observatory. The project took 3 years and 3 months to complete. There were 96 rides, totalling about 4900km. So my mean distance was around 51km. The median distance per ride was a little higher, at around 52 km, and the median duration (including stoppages) was about 2h40. The total duration, if you add them all up, including stoppages, was about 275h, giving a mean speed including photo stops, lunches and all, of 18kph. The longest ride was 89.8km, collecting Scotland Farm, Shepreth, and Six Mile Bottom, so riding across the Cam valley. The shortest ride was 7.9km, collecting Cambridge (obviously); and I think that s the only one I did on my Brompton. The rest were all on my trusty Thorn Audax. My fastest ride (ranking by distance divided by time spent in motion) was to collect Haddenham, where I covered 46.3km in 1h39, giving an average speed in motion of 28.0kph. The most I collected in one day was 5 places: West Wickham, West Wratting, Westley Bottom, Westley Waterless, and Weston Colville. That was the day of the Wests. (There s only one East: East Hatley.)

Dirk Eddelbuettel: #43: r2u Faster Than the Alternatives

Welcome to the 43th post in the $R^4 series. And with that, a good laugh. When I set up Sunday s post, I was excited enough about the (indeed exciting !!) topic of r2u via browser or vscode that I mistakenly labeled it as the 41th post. And overlooked the existing 41th post from July! So it really is as if Douglas Adams, Arthur Dent, and, for good measure, Dirk Gently, looked over my shoulder and declared there shall not be a 42th post!! So now we have two 41th post: Sunday s and July s. Back the current topic, which is of course r2u. Earlier this week we had a failure in (an R based) CI run (using a default action which I had not set up). A package was newer in source than binary, so a build from source was attempted. And of course failed as it was a package needing a system dependency to build. Which the default action did not install. I am familiar with the problem via my general use of r2u (or my r-ci which uses it under the hood). And there we use a bspm variable to prefer binary over possibly newer source. So I was curious how one would address this with the default actions. It so happens that the same morning I spotted a StackOverflow question on the same topic, where the original poster had suffered the exact same issue! I offered my approach (via r2u) as a comment and was later notified of a follow-up answer by the OP. Turns our there is a new, more powerful action that does all this, potentially flipping to a newer version and building it, all while using a cache. Now I was curious, and in the evening cloned the repo to study the new approach and compare the new action to what r2u offers. In particular, I was curious if a use of caches would be benficial on repeated runs. A screenshot of the resulting Actions and their times follows. Turns out maybe not so much (yet ?). As the actions page of my cloned comparison repo shows in this screenshot, r2u is consistently faster at always below one minute compared to new entrant at always over two minutes. (I should clarify that the original actions sets up dependencies, then scrapes, and commits. I am timing only the setup of dependencies here.) We can also extract the six datapoints and quickly visualize them. Now, this is of course entirely possibly that not all possible venues for speedups were exploited in how the action setup was setup. If so, please file an issue at the repo and I will try to update accordingly. But for now it seems that a default of setup r2u is easily more than twice as fast as an otherwise very compelling alternative (with arguably much broader scope). However, where r2u choses to play, on the increasingly common, popular and powerful Ubuntu LTS setup, it clearly continues to run circles around alternate approaches. So the saying remains: r2u: fast, easy, reliable. If you like this or other open-source work I do, you can now sponsor me at GitHub.

Bits from Debian: Debian Project Bits Volume 1, Issue 1

Debian Project Bits Volume 1, Issue 1 August 05, 2023 Welcome to the inaugural issue of Debian Project Bits! Those remembering the Debian Weekly News (DwN) will recognize some of the sections here which served as our inspiration. Debian Project Bits posts will allow for a faster turnaround of some project news on a monthly basis. The Debian Micronews service will continue to share shorter news items, the Debian Project News remains as our official newsletter which may move to a biannual archive format. News Debian Day The Debian Project was officially founded by Ian Murdock on August 16, 1993. Since then we have celebrated our Anniversary of that date each year with events around the world. We would love it if you could join our revels this very special year as we have the honor of turning 30! Attend or organize a local Debian Day celebration. You're invited to plan your own event: from Bug Squashing parties to Key Signing parties, Meet-Ups, or any type of social event whether large or small. And be sure to check our Debian reimbursement How To if you need such resources. You can share your days, events, thoughts, or notes with us and the rest of the community with the #debianday tag that will be used across most social media platforms. See you then! Events: Upcoming and Reports Upcoming Debian 30 anos The Debian Brasil Community is organizing the event Debian 30 anos to celebrate the 30th anniversary of the Debian Project. From August 14 to 18, between 7pm and 22pm (UTC-3) contributors will talk online in Portuguese and we will live stream on Debian Brasil YouTube channel. DebConf23: Debian Developers Camp and Conference The 2023 Debian Developers Camp (DebCamp) and Conference (DebConf23) will be hosted this year in Infopark, Kochi, India. DebCamp is slated to run from September 3 through 9, immediately followed by the larger DebConf, September 10 through 17. If you are planning on attending the conference this year, now is the time to ensure your travel documentation, visa information, bursary submissions, papers and relevant equipment are prepared. For more information contact: debconf@debconf. MiniDebConf Cambridge 2023 There will be a MiniDebConf held in Cambridge, UK, hosted by ARM for 4 days in November: 2 days for a mini-DebCamp (Thu 23 - Fri 24), with space for dedicated development / sprint / team meetings, then two days for a more regular MiniDebConf (Sat 25 - Sun 26) with space for more general talks, up to 80 people. Reports During the last months, the Debian Community has organized some Bug Squashing Parties:
Tilburg, Netherlands. October 2022. St-Cergue, Switzerland. January 2023 Montreal, Canada. February 2023 In January, Debian India hosted the MiniDebConf Tamil Nadu in Viluppuram, Tamil Nadu, India (Sat 28 - Sun 26). The following month, the MiniDebConf Portugal 2023 was held in Lisbon (12 - 16 February 2023). These events, seen as a stunning success by some of their attendees, demonstrate the vitality of our community.
Debian Brasil Community at Campus Party Brazil 2023 Another edition of Campus Party Brazil took place in the city of S o Paulo between July 25th and 30th. And one more time the Debian Brazil Community was present. During the days in the available space, we carry out some activities such as: For more info and a few photos, check out the organizers' report. MiniDebConf Bras lia 2023 From May 25 to 27, Bras lia hosted the MiniDebConf Bras lia 2023. This gathering was composed of various activities such as talks, workshops, sprints, BSPs (Bug Squashing Party), key signings, social events, and hacking, aimed to bring the community together and celebrate the world's largest Free Software project: Debian. For more information please see the full report written by the organizers. Debian Reunion Hamburg 2023 This year the annual Debian Reunion Hamburg was held from Tuesday 23 to 30 May starting with four days of hacking followed by two days of talks, and then two more days of hacking. As usual, people - more than forty-five attendees from Germany, Czechia, France, Slovakia, and Switzerland - were happy to meet in person, to hack and chat together, and much more. If you missed the live streams, the video recordings are available. Translation workshops from the pt_BR team The Brazilian translation team, debian-l10n-portuguese, had their first workshop of 2023 in February with great results. The workshop was aimed at beginners, working in DDTP/DDTSS. For more information please see the full report written by the organizers. And on June 13 another workshop took place to translate The Debian Administrator's Handbook). The main goal was to show beginners how to collaborate in the translation of this important material, which has existed since 2004. The manual's translations are hosted on Weblate. Releases Stable Release Debian 12 bookworm was released on June 10, 2023. This new version becomes the stable release of Debian and moves the prior Debian 11 bullseye release to oldstable status. The Debian community celebrated the release with 23 Release Parties all around the world. Bookworm's first point release 12.1 address miscellaneous bug fixes affecting 88 packages, documentation, and installer updates was made available on July 22, 2023. RISC-V support riscv64 has recently been added to the official Debian architectures for support of 64-bit little-endian RISC-V hardware running the Linux kernel. We expect to have full riscv64 support in Debian 13 trixie. Updates on bootstrap, build daemon, porterbox, and development progress were recently shared by the team in a Bits from the Debian riscv64 porters post. non-free-firmware The Debian 12 bookworm archive now includes non-free-firmware; please be sure to update your apt sources.list if your systems requires such components for operation.

Inside Debian New Debian Members Please welcome the following newest Debian Project Members: To find out more about our newest members or any Debian Developer, look for them on the Debian People list. Security Debian's Security Team releases current advisories on a daily basis. Some recently released advisories concern these packages: trafficserver Several vulnerabilities were discovered in Apache Traffic Server, a reverse and forward proxy server, which could result in information disclosure or denial of service. asterisk A flaw was found in Asterisk, an Open Source Private Branch Exchange. A buffer overflow vulnerability affects users that use PJSIP DNS resolver. This vulnerability is related to CVE-2022-24793. The difference is that this issue is in parsing the query record parse_query(), while the issue in CVE-2022-24793 is in parse_rr(). A workaround is to disable DNS resolution in PJSIP config (by setting nameserver_count to zero) or use an external resolver implementation instead. flask It was discovered that in some conditions the Flask web framework may disclose a session cookie. chromium Multiple security issues were discovered in Chromium, which could result in the execution of arbitrary code, denial of service or information disclosure. Other Popular packages gpgv - GNU privacy guard signature verification tool. 99,053 installations. gpgv is actually a stripped-down version of gpg which is only able to check signatures. It is somewhat smaller than the fully-blown gpg and uses a different (and simpler) way to check that the public keys used to make the signature are valid. There are no configuration files and only a few options are implemented. dmsetup - Linux Kernel Device Mapper userspace library. 77,769 installations. The Linux Kernel Device Mapper is the LVM (Linux Logical Volume Management) Team's implementation of a minimalistic kernel-space driver that handles volume management, while keeping knowledge of the underlying device layout in user-space. This makes it useful for not only LVM, but software raid, and other drivers that create "virtual" block devices. sensible-utils - Utilities for sensible alternative selection. 96,001 daily users. This package provides a number of small utilities which are used by programs to sensibly select and spawn an appropriate browser, editor, or pager. The specific utilities included are: sensible-browser sensible-editor sensible-pager. popularity-contest - The popularity-contest package. 90,758 daily users. The popularity-contest package sets up a cron job that will periodically anonymously submit to the Debian developers statistics about the most used Debian packages on the system. This information helps Debian make decisions such as which packages should go on the first CD. It also lets Debian improve future versions of the distribution so that the most popular packages are the ones which are installed automatically for new users. New and noteworthy packages in unstable Toolkit for scalable simulation of distributed applications SimGrid is a toolkit that provides core functionalities for the simulation of distributed applications in heterogeneous distributed environments. SimGrid can be used as a Grid simulator, a P2P simulator, a Cloud simulator, a MPI simulator, or a mix of all of them. The typical use-cases of SimGrid include heuristic evaluation, application prototyping, and real application development and tuning. This package contains the dynamic libraries and runtime. LDraw mklist program 3D CAD programs and rendering programs using the LDraw parts library of LEGO parts rely on a file called parts.lst containing a list of all available parts. The program ldraw-mklist is used to generate this list from a directory of LDraw parts. Open Lighting Architecture - RDM Responder Tests The DMX512 standard for Digital MultipleX is used for digital communication networks commonly used to control stage lighting and effects. The Remote Device Management protocol is an extension to DMX512, allowing bi-directional communication between RDM-compliant devices without disturbing other devices on the same connection. The Open Lighting Architecture (OLA) provides a plugin framework for distributing DMX512 control signals. The ola-rdm-tests package provides an automated way to check protocol compliance in RDM devices. parsec-service Parsec is an abstraction layer that can be used to interact with hardware-backed security facilities such as the Hardware Security Module (HSM), the Trusted Platform Module (TPM), as well as firmware-backed and isolated software services. The core component of Parsec is the security service, provided by this package. The service is a background process that runs on the host platform and provides connectivity with the secure facilities of that host, exposing a platform-neutral API that can be consumed into different programming languages using a client library. For a client library implemented in Rust see the package librust-parsec-interface-dev.

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

Valhalla's Things: Elastic Neck Top

Posted on July 26, 2023
A woman wearing a top in white fabric with thin blue lines and two groups of blue lozenges near the hems. It has a square neck gathered by a yellow elastic, the blue lines are horizontal on the wide sleeves and vertical, and more spaced, on the body. Since some time I ve been thinking about making myself a top or a dress with a wide gathered neckline that can be work at different widths, including off-the-shoulders. A few years ago I ve been gifted a cut of nice, thin white fabric with a print of lines and lozenges that isn t uniform along the fabric, but looks like it was designed for some specific garment, and it was waiting in my stash for a suitable pattern. And a few days ago, during a Sunday lunch, there was an off-hand mention of a dress from the late 1970s which had an elastic in the neckline, so that it could be optionally worn off-the-shoulders. And something snapped in place. I had plans for that afternoon, but they were scrapped, and I started to draw, measure, cut rectangles of fabric, pin and measure again, cut more fabric. The main pieces of the top laid flat: a big rectangle for the body,
two rectangular tubes for the sleeves laid so that they meet the body just at the corners, and a triangle (a square gusset folded on the diagonal) joins them to the body.
I decided on a pattern made of rectangles to be able to use as much fabric as possible, with the size of each rectangle based mostly on the various sections on the print of the fabric. I ve made the typical sleeves from a rectangle and a square gusset, and then attached them to the body just from the gusset to keep the neckline wide and low. The worn top shown from the side back: there is a strip of vertical lines spaced closer together like on the sleeves, and it continues to the bottom rather than ending with a strip of lozenges. The part of the fabric with large vertical stripes had two different widths: I could have made the back narrower, but I decided to just keep a strip with narrower lines to one side. The fabric also didn t have a full second strip of lozenges, so I had to hem it halfway through it. Closeup of the center front and center back of the neckline casing, showing the matched lines. The casing for the elastic was pieced from various scraps, but at least I was able to match the lines on the center front and back, even if they are different. Not that it matters a lot, since it s all hidden in the gathering, but I would have known. And since I was working on something definitely modern, even if made out of squares and rectangles, of course I decided to hand-sew everything, mostly to be able to use quite small sewing allowances, since the fabric was pretty thin. In my stash I had a piece of swimsuit elastic that feels nice, looks nice and makes a knot that doesn t slip, so I used it. It s a perfect match, except for the neon yellow colour, which I do like, but maybe is a bit too high visibility? I will see if the haberdasher has the same elastic in dark blue, but right now this will do. It was a quick project anyway: by the end of the working week the top was finished; I think that on a sewing machine it would be easy to make it in a day. the top worn with the neckline pulled down to leave the shoulders bare. And it can be worn off the shoulders! Which is something I will probably never do in public (and definitely not outdoors), but now if I wanted I could! :D As usual, the pattern (for what pattern there is) and instructions are on my pattern website under a #FreeSoftWear license, and I ve also added to the site a tip on how I use electrician fish tape to thread things through long casings

Scarlett Gately Moore: KDE Akademy 2023, Sunburns, and KDE Snaps

KDE Akademy 2023KDE Akademy 2023
A big thank you goes out to the Ubuntu Community for making my attendance to the KDE Akademy 2023! This was a very successful conference for me. I had very positive feedback for my speech on A million reasons why snaps are important. I also had a productive BoF on snapping KDE applications. Most importantly I got to catch up with many old and new friends and got to put faces to the new. There were so many great talks and BoFs, but one of my favorites was the Goals as all three compliment each other. The keynote was amazing, I had no idea open source has made its way into space! How cool is that!?! Despite the high temperatures ( something I am used to, but not that humidity! ) I had a wonderful time and was able to visit many cool sites in Greece. What an amazing place. In the snap world I haven t had much time this month as previous months as my part time gig doing them expired a few months ago and I had to focus on some paid work which has now run out. However, I did finish a new content pack containing KDE frameworks 5.108 and Qt 5.15.10 and most of KDE release applications 23.04.2. I also got Konsole working!
KDE Konsole snapKDE Konsole snap
I have some fixes merged into snapcraft that will fix some strange build errors reported on the forums and for myself as well. I will be creating a new PR for the new content pack as soon as testing is complete. We will have some very exciting news coming as soon as the t s are crossed and the i s are dotted. Until then I must reach out to the community for help to Keep the lights on until more paid work comes in. If it wasn t for all of you I couldn t make all of this possible and I thank each and every one of you. This is the greatest software community ever! https://gofund.me/018ddb06

Wouter Verhelst: Debconf Videoteam sprint in Paris, France, 2023-07-20 - 2023-07-23

The DebConf video team has been sprinting in preparation for DebConf 23 which will happen in Kochi, India, in September of this year. Video team sprint Present were Nicolas "olasd" Dandrimont, Stefano "tumbleweed" Rivera, and yours truly. Additionally, Louis-Philippe "pollo" V ronneau and Carl "CarlFK" Karsten joined the sprint remotely from across the pond. Thank you to the DPL for agreeing to fund flights, food, and accomodation for the team members. We would also like to extend a special thanks to the Association April for hosting our sprint at their offices. We made a lot of progress: It is now Sunday the 23rd at 14:15, and while the sprint is coming to an end, we haven't quite finished yet, so some more progress can still be made. Let's see what happens by tonight. All in all, though, we believe that the progress we made will make the DebConf Videoteam's work a bit easier in some areas, and will make things work better in the future. See you in Kochi!

Matt Brown: 2023 Mid Year Review

I m six months into my journey of building a business which means its time to reflect and review the goals I set for the year.

No further investment in co2mon.nz In March I made the decision to focus on completing the market research for co2mon.nz. The results of that research led to two key conclusions:
  1. Indoor air quality/ventilation is not a problem many people are actively thinking about or looking to spend money to improve.
  2. Even when introduced to the problem and educated about the need, most people are looking for a one-off expense or solution (e.g. the physical monitor) and are much less interested in a monitoring software service.
Based on that, it was clear that this is not an opportunity that I should continue pursuing and I ve put co2mon.nz into maintenance mode. I ve committed to maintaining the infrastructure to support existing customers, but I won t be investing time or energy in developing it further.

Discipline in selecting product opportunities The decision to stop investing more time into co2mon.nz was straightforward given the results of the research, but it was also painful given the time I ve already sunk into it. I hindsight it s clear that my enthusiasm to solve a problem with technology I enjoyed was my driving force rather than a deep understanding of the wants and needs of potential customers. I don t entirely regret trying my luck once - but it s not time efficient and I know that following that pattern again is not a sustainable or viable path to building a successful business. I ve decided to use the following list of questions to bring more discipline to how I evaluate product opportunities in future:
  1. Problem: Is this something that a sizeable number of people are struggling with AND are willing to spend money solving?
  2. Capability: Can I deliver a solution that solves the problem in a reliable and cost-effective way?
  3. Excitement: Am I excited and motivated to invest time in building the solution to this problem?
  4. Trust: Do I have the expertise and experience to be trusted to solve the problem by potential customers?
  5. Execution: Can I package, market and sell that solution in a profitable manner?
My plan is to answer these questions and then make an evaluation of the potential before I commit time to building any part of a product. As an example of how I think that will help, here s what I think the answer to those questions for ventilation monitoring would have been:
  1. Problem: No - as the market research eventually showed.
  2. Capability: Low - The part of the solution which customers primarily value (the hardware) is complex and outside of my core experience. The software I can easily deliver is not where the value is seen.
  3. Excitement: Yes - this was the primary driver of starting the project.
  4. Trust: Low - I m trusted to build software, but cannot claim any specific expertise in air quality and ventilation.
  5. Execution: Low confidence - These skills are not ones I ve exercised a lot in my career to date.
What these answers point to is that identifying the problem alone is not enough. I don t expect every question to have a perfect answer, but I want to hold myself to only pursuing opportunities where there s only one major area of doubt. In this case, even had the market research demonstrated a problem that many customers would pay to solve, there were still some big answers missing to the trust, capability and execution questions. Overall my conclusion is that co2mon.nz was not the ideal business to start my journey with given the number of open questions in the plan. I like to think that conclusion would also have been clear to me six months ago had I taken the time to go through this process then!

Prioritising areas of growth Applying those questions to my other product ideas results in a lot of I don t know yet answers to the problem and capability questions, further reinforcing the lesson that I need to spend more understanding if there is a problem with a viable business model attached in those areas before progressing any of those ideas. Beyond that lesson, a more interesting observation comes from the last question regarding execution. My answers to the first four questions vary between ideas, but my answers to this last question are always the same - I don t have a lot of confidence in my sales and marketing skills to sell a product. That s not a surprise. My career to date has been focused on software development and leadership, I don t have a lot of experience with sales and marketing. The opportunity to grow and develop those skills is actually a large part of my motivation for choosing the path of building my own business. But seeing that this is a common factor that will need significant investment regardless of which opportunity I pursue sends me a strong signal that I should focus on growth in this area as a priority. Following that logic through to the next step of what creating that focus would look like reveals a conflict: The nature of the mission I ve set for myself draws me to products in areas that are new to me, which means there s also a need to invest in building expertise in those areas. Again not a surprise, but the time and focus required to develop that expertise competes with time spent growing my sales and marketing skills. So I have a prioritisation problem. Solving it is going to require changing the type of product I m trying to build in the short term: I need to build a product that uses my existing expertise and strengths as much as possible, so that I can put the majority of my energy into growing the core business skills where my confidence is currently lacking. Trying to deliver meaningful improvements to a big problem in an area I don t have past experience in while also learning how to sell and market a product is biting off more than I chew right away.

Changing the goal posts With those lessons in hand I m making three changes to my 2023 Goals:
  1. Reducing the product development goal from several ideas to two. The first was co2mon.nz. The second will be drawn from my existing expertise - not one of the previously stated ideas that require me to develop expertise in a new area.
  2. Moving the consulting and product development goals to be alternatives - I expect I can achieve at most one of them this year.
  3. Reducing the publishing target for this site from at least once a week to once a month . I thought I d have more to say this year, but the words are coming very slowly to me.
Reducing scope and ambition is humbling, but that s reality. I hope it turns out to be a case of slow down and lay the foundations in order to then move faster. The good news is that I don t feel the need to make any changes to the vision, mission and strategy I m following - I think they re still the right destination and overall path for me even though the first six months has proven bumpy. I just need to be a bit more realistic on the short-term goals that will feed into them.

The next few months I m choosing to prioritise the product development goal. I m aiming to complete the market research/problem definition phase for a product opportunity I ve identified in the SRE/DevOps space (where my previous experience is) and make a decision on whether to start development by mid August. In making that decision I plan to gather the answers to my questions, and then diligently evaluate whether the opportunity is worth committing to or not. I will write more about this process in coming weeks. If I decide to proceed that gives me 2-3 months to get an MVP in the hands of customers and get concrete validation of whether the product has revenue and growth potential before the end of the year. Tight, but if things go well, and I don t take any further consulting work, there s a reasonable chance I can complete the revised goal successfully. In the event that I decide the product opportunity I m currently researching is not the right one to commit to, I will likely revert to focusing on my consulting goal in the remaining 2-3 months of the year rather than attempt a third product development iteration. Thanks for reading this far! As always, I d love your thoughts and feedback.

Appendix: Revised 2023 Goals Putting all that together, the ultimate outcome of this review (including updated progress scoring) looks like:
  1. Execute a series of successful consulting engagements, building a reputation for myself and leaving happy customers willing to provide testimonials that support a pipeline of future opportunities. Score: 3/10 - I focused entirely on co2mon.nz during April, May and June to the detriment of my pipeline of consulting work. This score is unlikely to improve given the above plan unless I decide not to commit to developing the idea I m currently investigating.
  2. Grow my product development skill set by taking two ideas (co2mon.nz, an SRE/DevOps focused product) to MVP stage with customer feedback received, and generate revenue and has growth potential from one of them. Score: 4/10 - I launched co2mon.nz and got feedback, I discovered it didn t solve a problem relevant to customers and therefore did not generate substantial revenue or growth potential. Idea number two is in still in progress.
  3. Develop and maintain a broad professional network.
    1. To build a professional relationship with at least 30 new people this year. Score: 6/10 - This is going well. On track for a 10/10 score.
    2. To publish a piece of writing on this site once a month and for many of those to generate interesting conversations and feedback. Score: 6/10 - 4 out of 6 months have featured a post meeting this goal so far.
    3. To support the growth of my local technical community by volunteering my experience and knowledge with others. Score: 5/10 - I ve given one talk and helped with SREcon23 APAC, but not as much other work in this area as I d like.

Shirish Agarwal: Motherboard battery, Framework, VR headsets, Steam

Motherboard Battery You know you have become too old when you get stumped and the solution is simple and fixed by the vendor. About a week back, I was getting CPU Fan Error. It s a 6 year old desktop so I figured that the fan or the ball bearings on the fan must have worn out. I opened up the cabinet and I could see both the on cpu fan was working coolly as well as the side fan was working without an issue. So I couldn t figure out what was the issue. I had updated the BIOS/UEFI number of years ago so that couldn t be an issue. I fiddled with the boot menu and was able to boot into Linux but it was a pain that I had to do every damn time. As it is, it takes almost 2-3 minutes for the whole desktop to be ready and this extra step was annoying. I had bought a Mid-tower cabinet while the motherboard so there were alternate connectors I could try but still the issue persisted. And this workaround was heart-breaking as you boot the BIOS/UEFI and fix the boot menu each time even though it had Debian Boot Launcher and couple of virtual ones provided by the vendor (Asus) and they were hardwired. So failing all, went to my vendor/support and asked if he could find out what the issue is. It costed me $10, he did all the same things I did but one thing more, he changed the battery (cost less than 1USD) and presto all was right with the world again. I felt like a fool but a deal is a deal so paid the gentleman for his services. Now can again use the desktop and at least know about what s happening in the outside world.

Framework Laptops I have been seeing quite a few teardowns of Framework Laptops on Youtube and love it. More so, now that they have AMD in their arsenal. I do hope they work on their pricing and logistics and soon we have it here competing with others. If the pricing isn t substantial then definitely would be one of the first ones to order. India is and remains a very cost-conscious market and more so with the runaway prices that we have been seeing. In fact, the last 3 years have been pretty bad for the overall PC market declining 30% YoY for the last 3 years while prices have gone through the roof. Apart from the pricing from the vendors, taxation has been another hit as the current Govt. has been taxing anywhere from 30-100% taxes on various PC, desktop and laptop components. Think have shared Graphic cards for instance have 100% Duty apart from other taxes. I don t see the market picking up at least in the 24 to 36 months. Most of this year and next year, both AMD and Intel are doing refreshes so while there would be some improvements (probably 10-15%) not earth-shattering for the wider market to sit up and take notice. Intel has proposed a 64-bit architecture (only) about couple of months back, more on that later. As far as the Indian market is concerned, if you want the masses, then have lappies at around 40-50k ($600 USD) and there would be a mass takeup, if you want to be a Lenovo or something like that, then around a lakh or INR 100k ($1200 USD) or be an Apple which is around 150k INR or around 2000 USD. There are some clues as to what their plans but for that you have to trawl their forums and the knowledgebase. Seems some people are using freight forwarders to get around the hurdles but Framework doesn t want to do any shortcuts for the same. Everybody seems to be working on Vertical stacking of chips, whether it is the Chinese, or Belgian s or even AMD and Intel who have their own spins to it, but most of these technologies are at least 3-4 years out in the future (or more). India is a big laggard in this space with having knowledge of 45nm which in Aviation speak one could say India knows how to build 707 (one of the first Boeing commercial passenger carrying aircraft) while today it is Boeing 777x or Airbus 350. I have shared in the past how the Tata s have been trying to collaborate with the Japanese and get at least their 25nm chip technology but nothing has come of it to date. The only somewhat o.k. news has been the chip testing and packaging plant by Micron to be made in Gujarat. It doesn t do anything for us although we would be footing almost 70% of the plant s capital expenditure and the maximum India will get 4k jobs. Most of these plants are highly automated as dust is their mortal enemy so even the 4k jobs announced seem far-fetched. It would probably be less than half once production starts if it happens but that is probably a story for another time. Just as a parting shot, even memory vendors are going highly automated factory lines.

VR Headsets I was stuck by how similar or where VR is when I was watching Made in Finland. I don t want to delve much into the series but it is a fascinating one. I was very much taken by the character of Kari Kairamo or the actor who played the character of him and was very much disappointed with the sad ending the gentleman got. It is implicated in the series that the banks implicitly forced him to commit suicide. There is also a lot of chaos as is normal in a big company having many divisions. It s only when Jorma Olila takes over, the company sheds a lot of dead weight was cut off with mobiles having the most funding which they didn t have before. I was also fascinated when I experienced pride when Nokia shows off its 1011 mobile phone when at that time phones were actually like bricks. My first Nokia was number of years later, Nokia 1800 and have to say those phones outlasted a long time than today s Samsung s. If only Nokia had read the tea leaves right Back to the topic though, I have been wearing glasses since the age of 5 year old. They weigh less than 10 grams and you still get a nose dent. And I know enough people, times etc. when people have got headaches and whatnot from glasses. Unless the VR headsets become that size and don t cost an arm and leg (or a kidney or a liver) it would have niche use. While 5G and 6G would certainly push more ppl to get it it probably would take a few more years before we have something that is simple and doesn t need too much to get it rolling. The series I mentioned above is already over it s first season but would highly recommend it. I do hope the second season happens quickly and we do come to know why and how Nokia missed the Android train and their curious turn to get to Microsoft which sorta sealed their fate

Steam I have been following Steam, Luthris and plenty of other launchers on Debian. There also seems to some sort of an idea that once MESA 23.1.x or later comes into Debian at some point we may get Steam 64-bit and some people are hopeful that we may get it by year-end. There are a plethora of statistics that can be used to find status of Gaming on Linux. This is perhaps the best one I got so far. Valve also has its own share of stats that it shows here. I am not going to go into much detail except the fact that lutris has been there on Debian sometime now. And as and when Steam does go fully 64-bit, whole lot of multilib issues could be finally put to rest. Interestingly, Intel has quietly also shared details of only a 64-bit architecture PC. From what I could tell, it simply boots into 16-bit and then goes into 64-bit bypassing the 32-bit. In theory, it should remove whole lot code, make it safer as well as faster. If rival AMD was to play along things could move much faster. Now don t get me wrong, 32-bit was good, but for it s time. I m sure at some point in time even 64-bit would have its demise, and we would jump to 128-bit. Of course, in reality we aren t anywhere close to even 48-bit, leave alone 64-bit. Superuser gives a good answer on that. We may be a decade or more before we exhaust that but for sure there will be need for better, faster hardware especially as we use more and more of AI for good and bad things. I am curious to see how it pans out and how it will affect (or not) FOSS gaming. FWIW, I used to peruse freegamer.blogspot.com which kinda ended in 2021 and now use Lee Reilly blog posts to know what is happening in github as far as FOSS games are concerned. There is also a whole thing about handhelds and gaming but that probably would require its own blog post or two. There are just too many while at the same time too few (legally purchasable in India) to have its own blog post, maybe sometime in Future. Best way to escape the world. Till later.
