I don’t know if it’s early spring and articles I found interesting are sprouting anywhere… In any case this week issue is massive. Brace yourselves and let’s go for my web review for the week 2023-08.

Google Greenwashes a Dirty Partnership with Saudi Aramco

Tags: tech, google, greenwashing, ecology, ethics

This is indeed a massive greenwashing operation right there. And then they will claim things like “AI for good” or such…

AMD CEO: The Next Challenge Is Energy Efficiency - IEEE Spectrum

Tags: tech, cpu, performance, energy, architecture

Interesting position from AMD regarding the race on the next super computers. They’re all being caught up by energy efficiency so it’ll need to be addressed both at the processor architecture level but also at the software architecture level. How we design our computing tasks will matter more and more.

We need to talk about your Github addiction

Tags: tech, github, criticism, foss

Social Media is a Major Cause of the Mental Illness Epidemic in Teen Girls. Here’s The Evidence.

Tags: tech, social-media, science, criticism

Lengthy but thorough. The evidences are now getting much clearer. Admittedly, the most worrying bit I find is that getting off the social media wagon might not help the impacted people to get better… indeed they might still be isolated if everyone else is still trapped on social media.

If you didn’t have an adblocker yet (who doesn’t really?) it’s time to really think about it. When even the FBI starts to advocate for ad blockers it’s a sign of how bad the online ad market has become.

Can We Trust Search Engines with Generative AI? A Closer Look at Bing’s Accuracy for News Queries | by Nick Diakopoulos | Feb, 2023 | Medium

Tags: tech, ai, gpt, search

Inaccuracies, contradicting itself, conflating events, misquoting sources… all of that mixed with some correct facts, it’s a perfect misinformation spreading machine. This just can’t be trusted at this point. Those experiments should be stopped in my opinion, better do proper homeworks first, then relaunch when this can be better trusted.

Large language models will change programming… a little | by Amy J. Ko

Named Booleans prevent C++ bugs and save you time - Raymii.org

I love building a startup in Rust. I wouldn’t pick it again. | PropelAuth Blog

Tags: tech, programming, rust

That’s an interesting perspective. Rust definitely gets in the way of iterating quickly indeed which might be a problem to test ideas. Introducing it gradually later is thus a better path. That being said it doesn’t always have a great story for mixing with other languages, there are a few tools to help, but nothing I’ve seen really used in the wild so far (this will probably come though).

React Is Holding Me Hostage

Tags: tech, frontend, web, react

A bit of a rant, but even though React is well established at that point and here to stay (shake a tree and half a dozen React developers fall from it), it doesn’t mean it can’t be criticized. It does a good job at listing the main ergonomics problems React is suffering from. The funny part is towards the end, the envisioned solutions for another framework look eerily familiar to a Qt developer, it talks about signals and what looks like property changed notifications. :-)

advice you might as well take

Tags: tech, xp, yagni

YAGNI is one of the easiest to misunderstood ideas behind eXtreme Programming. That’s why I think it’s a good thing it stays under active discussion. Often people understand it too literally which can create issues. That’s why people talking about “PAGNI” (probably are gonna need it) are right. After all, people who also conceptualized YAGNI wrote back then: “This doesn’t mean you should avoid building flexibility into your code”.

The age of cargo cult Agile must end. | by Jason Yip

Stop Obsessing Over Development Velocity, Focus on This Instead - Itamar Gilad

Bye for now!

Manjaro ARM is proud to present the packages for Plasma 5.27.0 together with the packages for Plasma Mobile Gear (soon to be regular Gear) 23.01.0 for the mobile devices.

These packages are currently being tested in our Unstable branch and will soon be transferred to Testing and then finally to Stable branch when the time comes..

This also makes our next Beta images (Beta 15) the last that will be tagged as Beta. We are preparing to include PinePhone and PinePhone Pro images into our main release cycle from either 23.04 or 23.06.

How to try

If you want to try this early, you can switch your current Manjaro system running Plasma mobile to Unstable branch and update this way:

sudo pacman-mirrors -aS unstable
sudo pacman -Syyu

Some new features

New features in this release/update includes, but are not limited to:

• New Power Off Menu
• More KCMs are mobile friendly
• Added User KCM (although it does not save changes)
• Lots of under-the-hood changes and fixes

And a couple of screenshots:

I am happy to announce Tokodon 23.02. This release contains around one month’s worth of improvements, and while it is only one month, this release is feature packed! This was an exciting month for me in general, I started working at KDAB, went to FOSDEM in Brusels where I meet a bunch of other KDE folks, and spend time enjoying my new life in Berlin.

Fortunately I still found some time to contribute to Tokodon, and Joshua Goins has also been a very active contributor. The number of contributors is also growing with a bunch of new faces: Aakarsh MJ, Harshil Jani, Mohit Marathe, Raphael Gaschiganrd, Rishi Kumar who also contributed some code in this release.

So what is Tokodon? Is is basically a client for the federated social network Mastodon. It is built with Kirigami with the goal to have a great integration with Plasma Desktop and Plasma Mobile, but it also works on other desktop environments, and even Windows and macOS.

Get it!

You can download Tokodon 23.02.0 from Flathub and from F-Droid using the KDE repo. Currently we don’t offer binaries for Windows and macOS but if you want to help with that, please get in touch on Matrix.

Post composer rewamp

As part of this release, we reworked the post composer considerably. This is the central area of your interaction with Mastodon and we wanted it to be more reliable.

It is now possible to add an alternative description to images and videos sent via Tokodon. This is very important for accessibility as images without alternative description are invisible for screen readers. (Carl Schwan, Link)

It is also now possible to see the upload progress when uploading an attachment, giving you some visual feedback that something is happening. (Carl Schwan, Link)

An error message will be displayed when sending a message didn’t work. The post composer will only be closed once the message is sent, so if there is an network error the post you wrote is not lost and you can try posting it again. This should make Tokodon much more reliable for interacting with Mastodon. (Joshua Goins, Link).

Another big thing is that we are now supporting editing posts, so in case you made a typo you don’t need to delete your post and post it again. (Joshua Goins, Link)

And finally Tokodon respects your default sensibility and visibility preferences when posting, and when replying to a message, the visibility of the message will be inherited in your reply. So if you are replying to a private message, the reply will automatically be set to be also private. (Carl Schwan, Link)

Timeline and notification view

Aside from the improvements to the post editor, we continued to polish the timeline.

The models for timelines has been completely refactored. Aside from making the code nicer to work with and a bit faster, it also made it possible to show the avatar of who boosted or liked a post. (Carl Schwan, Link)

Tokodon now doesn’t only support image as attachments, but we now also have a prelimary support for videos and gifs. (Joshua Goins, Link).

Additionally the previews for attachements should be better displayed with correct aspect ratio. (Joshua Goins, Link 1, Link 2)

Other ways to interact with a post are now available in an overflow menu for posts adding actions like a “Copy link to post” feature (Joshua Goins, Link), a bookmark feature (Joshua Goins, Link) and the previously mentioned edit feature (Joshua Goins, Link)

There are now some new special pages available in the sidebar to display your bookmarks as well as your favorite posts. (Joshua Goins, Link)

We now handle notifications for poll updates (Riya Bisht, Link), and when a post you interacted with gets updated (Harshil Jani, Link)

There are now placeholders for when you currently don’t have any notifications or conversations instead of showing you an empty view (Mohit Marathe, Link)

Search

The search field introduced during the last released got a nice visual refresh…

… And it now supports searching for hashtags. (Joshua Goins, Link)

Other Improvements

It is now possible to configure the color scheme used by Tokodon independently from the Plasma color scheme. (Joshua Goins, Link but most of the code was copied in good tradition from NeoChat)

We added the missing separators in the settings pages (Rishi Kumar, Link)

It is now possible to directly edit your account from your profile page (Joshua Goins, Link)

The user’s avatar in the profile page now uses the standard Kirigami.Avatar component (Joshua Goins, Link)

The behavior of selectable text fields is now consistent (Aakarsh MJ, Link)

Important Bugfixes

A bug that broke loading the timeline in some conditions has been fixed (Carl Schwan, Link)

We fixed rendering of some attachments caused by a bug in the blurhash decoding. (Joshua Goins, Link)

Storing the account settings is now using the account username and instance hostname as a unique identifier. This fixes situations where someone had multiple accounts with the same username on a different instance. (Raphael Gaschiganrd, Link)

Technical Details

Aside from the many new features, there were several large re-factorings of the code base to cleanup some code that younger-me wrote. The C++ code base now has a coverage of 36%, this is a small increase compared to the previous release. Rishi Kumar is also working on integration tests as part of his Season of KDE project.

Get Involved

If you are interested in helping, don’t hesitate to reach out in the Tokodon matrix channel (#tokodon:kde.org) and I will be happy to guide you.

I’m also regularly posting about my progress on Tokodon (and other KDE apps) on my Mastodon account, so don’t hesitate to follow me there ;)

And in case, you missed it, as a member of the fundraising working group, I need to remind you that KDE e.V., the non-profit behind the KDE community accepts donations.

Packager section

You can find the package on download.kde.org and it has been signed with my GPG key.

After the announcement upstream, Fedora’s @kde-sig follows up by making KDE Plasma 5.27.0 available on Fedora 36 and Fedora 37.

There’s a catch though: you will have to use our COPR.

The regular update on Fedora repositories will follow shortly, I will keep you all posted.

Feel free to join us at our Matrix room!.

Glaxnimate is proud to announce the release of version 0.5.2. This latest update brings several exciting new features and improvements to enhance your animation creation experience.

Animation along Path

Earth and Moon graphics are from Noto Emoji

One of the major additions in this release is the ability to animate objects along a path. This is a feature that allows you to animate elements in a more natural and organic way by having them move along a custom path instead of a straight line. With this feature in Glaxnimate, you can create animations of objects following a curved path, like a bouncing ball or a spaceship flying through space.

After you add position keyframes to an object, the path can be adjusted with the edit tool, giving you full control over the motion of your elements, and the ability to fine-tune your animations until they look just right.

Improved User Interface

The interface layout has also been updated with new presets to provide better display on smaller screens, and the ability to set custom shortcut settings for plugins has been added.

Enhanced Input/Output Functionality

To make your workflow even easier, a new export option as an image sequence has been added to the menu.

This release also brings support for loading and saving Rive animations, improving the quality of video exports, and adding command line options for rendering images without starting the GUI.

Issues with loading Glaxnimate and old Lotties files have also been resolved, as well as a crash on SVG export.

Scripting Additions

For developers and advanced users, the new release features a function to render a node at a specific frame, providing even more control over your animations.

Bug Fixes and Minor Enhancements

This release also includes several bug fixes, including resolution of issues with loading Lotties with hidden fill and stroke, improved previews in the stroke style view, and proper application of duration changes in the startup dialog to all layers.

Additionally, Glaxnimate 0.5.2 includes the addition of Flatpak, improved Freedesktop file naming and metainfo, and the ability to view contributors. Messages are also logged to a file for better tracking of errors and issues.

The Select tool has also been improved, allowing for better handling of ungrouped shapes, making your editing process smoother and more efficient.

Download

We are confident that these new features and improvements will enhance your experience with Glaxnimate and look forward to continuing to bring you the best vector animation application.

If you're interested in trying it out, head over to our download page to get started. As always, if you have any questions or feedback, feel free to reach out to us via our issue tracker.

Thank you for your continued support of Glaxnimate!

Interesting post with a good perspective on big data projects over time. It confirms that most people don’t fall in the big data bucket, it’s likely less than a percent of the projects which would qualify.

GitHub - hubblo-org/scaphandre: ⚡ Energy consumption metrology agent.

Tags: tech, energy

Looks like a young but interesting tool to assess the power consumption of a service. There’s been quite some work in this domain on the client side, not so much on the server side. This is welcome.

C++ Alternative Operators

Tags: tech, c++

This is lesser known and probably should stay obscure… don’t do that at home kids. Those alternative operators (more like tokens really) don’t help with readability at all and make not much sense with UTF8 code bases.

Very good essay on why we shouldn’t look down on the Luddite. They had plenty of their questioning right and it’s actually pervasive now. We use the term as libel only because back then they lost…

Bye for now!

As announced previously, Plasma 5.27 will have a significantly reworked multiscreen management, and we want to make sure this will be the best LTS Plasma release we had so far.

Of course, this doesn’t mean it will be perfect from day one, and your feedback is really important, as we want to fix any potential issue as fast as they get noticed.

As you know, for our issue tracking we use Bugzilla at this address. We have different products and components that are involved in the multiscreen management.

First, under New bug, chose the “plasma” category. Then there are 4 possible combinations of products and components, depending on the symptoms:

In order to have a good complete information on the affected system, its configuration, and the configuration of our multiscreen management, if you can, the following information would be needed:

• Whether the problem happens in a Wayland or X11 session (or both)
• A good description of the scenario: how many screens, whether is a laptop or desktop, when the problem happens (startup, connecting/disconnectiong, going out of sleep and things like that)
• The output the terminal command: kscreen-doctor -o
• The output of the terminal command: kscreen-console
• The main plasma configuration file: ~/.config/plasma-org.kde.plasma.desktop-appletsrc

Those items of information already help a lot figuring out what problem is and where it resides.

Afterwards we still may ask for more informations, like an archive of the main screen config files that are the directory content of ~/.local/share/kscreen/ but normally, we wouldn’t need that.

One more word on kscreen-doctor and kscreen-console

Those 2 commands are very useful to understand what Plasma and the rest of the system thinks about every screen that’s connected and how they intend to treat them.

kscreen-doctor

Here is a typical output of the command kscreen-doctor - o:

Output: 1 eDP-1 enabled connected priority 2 Panel Modes: 0:1200x1920@60! 1:1024x768@60 Geometry: 1920,0 960x600 Scale: 2 Rotation: 8 Overscan: 0 Vrr: incapable RgbRange: Automatic

Output: 3 DP-4 enabled connected priority 1 DisplayPort Modes: 0:1920x1080@60*! 1:1920x1080@60 2:1920x1080@60 3:1680x1050@60 4:1600x900@60 5:1280x1024@75 6:1280x1024@60 7:1440x900@60 8:1280x800@60 9:1152x864@75 10:1280x720@60 11:1280x720@60 12:1280x720@60 13:1024x768@75 14:1024x768@70 15:1024x768@60 16:832x624@75 17:800x600@75 18:800x600@72 19:800x600@60 20:800x600@56 21:720x480@60 22:720x480@60 23:720x480@60 24:720x480@60 25:640x480@75 26:640x480@73 27:640x480@67 28:640x480@60 29:640x480@60 30:720x400@70 31:1280x1024@60 32:1024x768@60 33:1280x800@60 34:1920x1080@60 35:1600x900@60 36:1368x768@60 37:1280x720@60 Geometry: 0,0 1920x1080 Scale: 1 Rotation: 1 Overscan: 0 Vrr: incapable RgbRange: Automatic

Here we can see we have 3 outputs, one internal and two via DisplayPort, DP-4 is the primary (priority 1) followed by eDP-1 (internal) and DP-3 (those correcpond to the new reordering UI in the systemsettings screen module).

Important data points, also the screen geometries (in italic in the snippet) which tell their relative positions.

kscreen-console

This gives a bit more verbose information, here is a sample (copied here the data of a single screen, as the output is very long):

Important also the section EDID Info, to see if the screen has a good and unique EDID, as invalid Edids, especially in combination with DisplayPort is a known source or problems.

Like others, I’m sitting in the train from Brussels to Paris after a very intensive week-end. Indeed, FOSDEM 2023 did happen. After being suspended for two years during the pandemic, at least for the in person version, it is back. I couldn’t ignore this and had to go!

Now let’s see for my quick and very own biased recap of the week-end.

The Talks

I managed to attend a few talks and take written notes. I miss my old tablet, I would have preferred to get back into sketch noting. Maybe next time…

Graphics: A Frame’s journey

A nice talk from Daniel Stone who really knows the topic in depth. I admit I expected something a bit less high level though. Still, if you are curious about how the graphics stack is structured on Linux it was definitely worth attending.

It does a very good job about explaining DRM/KMS, EGL, GBM respective roles and how they align. Also shows how Wayland is purposefully aligned with KMS. I managed to get a few extra information I didn’t expect on the topic.

Definitely recommended.

4K HDR video with AV1: A Reality Check

It’s been a few years now that I end up attending a talk I didn’t expect for various reasons. This year it was definitely this one, I didn’t mark it down at all on my hit list but ended up being in the Open Media room when it was presented.

It was definitely outside my comfort zone and still I found it very interesting and accessible enough. It explained quite well HDR content display and how AV1 handles it.

I admit I was a bit fascinated by the part talking about testing the rendering and if the standards are properly respected. It’s clearly a very complex work. Lots of very subtle details to get a test lab right. Indeed you even need to take care of the immediate environment of the lab since it can impact the perception of colors!

Unexpected as I said but I don’t regret it.

Understanding the energy use of Firefox

Nowadays I’m definitely getting more curious about the energy use of the software we use daily… and what is more commonly used nowadays than your web browser really?

Well, this is in part why the Mozilla people added energy profiling to the Firefox Profiler. It’s not only important from a sustainability, it also has a direct impact on the user experience in terms of noise, heat and battery use.

This type of profiling requires to look at CPU use, GPU use, thread wake ups, network use. They tended to waste energy a lot due to wake ups, invisible animations, timers. They introduced tooling around the task manager to ease hunting down those problems.

This coupled to telemetry allowed them to have a global picture of how the browser operates in the wild. The total daily consumption globally would require a small power station to satisfy it. Definitely not a small thing!

Anyway, it all allowed them to make several targeted fixes which improved the situation greatly. Still more improvements needed of course and experiments to run to see how they’ll behave in the wild.

Interesting stuff and definitely a tool I’ll use in the future, because… well see the next talk.

What’s new with the Firefox Profiler

I stayed in the same room to know more about the new features around the Firefox Profiler. Unfortunately it started late and needed to be a bit rushed.

They added nice improvements to it recently like - power profiling (with Watts and CO2 estimations) - source code view and inline call stacks - one click profiling for tabs - localization - lots of documentation improvements

But the thing I’m the most excited about is the importers they added. This turns it into a generic interface to explore profiler data and this one being very nice and thorough… Right now they can import traces from: chromer, perf, ART trace and callgrind. There’s even a Java JFR profiler compatible with it.

I find it really cool to see an ecosystem growing around it.

Open Source in Environmental Sustainability

This one was really not what I expected. I was looking for something on how FOSS project can do better in terms of Environmental Sustainability, it was more a survey about FOSS projects aiming at environmental sustainability topics. Fair enough, I was wrong, still worth listening to.

Unfortunately I didn’t find it very well delivered, the pace was a bit too slow or maybe energy was a bit lacking. Also they were some biases in the information collected or what they were looking at which rubbed me the wrong way.

Still I got a few interesting nuggets out of it. There seems to be an overly large presence of the communities, academia and governmental agencies in such projects. Companies are almost nowhere to be seen. Somehow the incentives must be lacking.

It also showed how well green washing unfortunately works. The current investment ratings in term of sustainability are definitely untrustworthy. For instance, the disconnect between carbon credits and the amount of carbon storage really happening is staggering.

I thus agree with the diagnostics, the models used for those ratings should be opened. This is necessary for provability and traceability. This indeed makes Open Source the most underestimated strategy for climate sustainability. Without it we can be easily misled.

Deep Dive Into Query Performance

For this one the title was very much misleading. It had nothing to do with a deep dive and was very much high level.

The advices were sound of course but I expected to learn more and get more tips on how to squeeze performance out of queries not only diagnose where the bottlenecks are.

Still I got away with a few tools to look at and assess if they can really help us - SQLcommenter to pass metadata to the database; - pg_stat_monitor to get deeper query performance insights.

So clearly not the best talk I’ve seen. The tools mentioned might be worth checking out.

Matrix 2.0

I was very curious to get news about Matrix progress. Also Matthew Hodgson is a good speaker and entertainer so hoped it’d be time well spent.

It definitely was! The amount of progress from the Matrix community is just very impressive. In his demo packed talked we’ve been shown: - how much the performance overall improved - how the multiparty VoIP features are doing great - the possibilities to have down the line a Matrix in P2P mode - and their new ThirdRoom client which provides virtual spaces features, I’m especially excited about its use of glTF as the base scene format and the fact that it works with the WebXR APIs

It was also great to see that more governments and agencies are making use of it now. It’s clearly spreading and getting traction. Hopefully the Digital Market Act will push further that momentum and the development of the bridges.

Very interesting times for this protocol, let’s hope it keeps going strong.

The enioka Gang

It’s been a few years that a few enioka Haute Couture developers have been attending FOSDEM. This year more of us did attend and also we managed to bring people from our sister company enioka Consulting with us. Our group thus exploded in size with a head count well above 15!

I thought it was a good opportunity to run a little experiment and asked them each to tell me about their favorite talk of the week-end. Here is what they came up with.

• DuckDB: Bringing analytical SQL directly to your Python shell
  This is a column database embedded in a Python process (although other bindings are available). It’s kind of a column based sqlite providing zero copy integration with Pandas and Numpy. All of this while providing a 100% SQL based interface.

• Building a Semantic Search Application in Python, Using Haystack
  How to easily create semantic search applications using this NLP framework and models from HuggingFace. This was an interesting talk about a tool which will be very useful to us.

• Automated short term train planning on OSRD
  How to insert a train at the last minute in a trafic plan defined weeks ago. The SNCF network works on this problem WITHOUT using AI!

• Similarity Detection in Online Integrity
  Collection of tools developed by Meta to identify pictures and videos to be considered “illegal”. It’s interesting to see the diversity of solutions they use, ranging from hash comparison to neural network. The platforms collaborate there through NCMEC, a solution to share detected illegal content. If you’re concerned your nudes might leak you can get them on the NCMEC list and avoid their publication. Forgotten from this talk is obviously the content moderators. Meta claims to rely on its “community” (sic).

• pip install malware
  A dynamic talk which shows the best practices and things to pay attention to when producing a library published via a package manager (like pip). It covers how malevolent packages can be installed by typo squatting, “hidden” dependencies, popularity theft (starjacking) and how to prevent it.

• Kerberos PKINIT: what, why, and how (to break it) An accessible explanation of Kerberos and of the PKINIT extension allowing to use X509 certificates to authenticate users. I also covers how its FreeIPA implementation could lead to privilege escalation.

• A deep dive inside the Rust frontend for GCC
  Nice presentation and progress report on the GCC frontend to compile Rust code.

• OpenSTEF: Open Source energy predictions
  A use case of Open Source tool to manage energy. In particular to predict congestions on the electrical grid.

• Understanding the energy use of Firefox
  How telemetry helps to figure out Firefox’s energy consumption, and how its profiling tools allow to optimize this consumption.

• Melrōse, a music programming environment
  A python framework to generate MIDI sequences. It comes with an advanced language to write melodies, harmonies and rythmes altogether. For me the main interest in the framework are the methods which allows to easily compose. Also the code is reinterpreted at each iteration so the generated sequence can be modified from one loop to the next.

• Kotlin Multiplatform for Android & iOS library developers
  Return on experience of two developers using Kotlin for Android and iOS native applications. They showed how to best leverage Kotlin by fine tuning and working around OS specific bugs with annotations.

• Application Monitoring with Grafana and OpenTelemetry
  Or how to monitor your applications with Open Source tools to store and explore as a whole the traces, logs and metrics.

The Hallway Track

As you can notice, I didn’t attend many talks… That’s because FOSDEM main value comes from the “hallway track”. It’s best to meet and chat with people as much as possible. And I can tell you it did happen!

It was a real pleasure to reconnect with people I appreciate and love there. Hugs, conversations and drinks were in order. Thank you all for that, hope to see you all again soonish!

It was also nice to meet new friendly faces. For instance, I used the opportunity to congrats the Penpot people for announcing their official launch (what they’re doing is really exciting and important, I wish them success).

But now it’s over… Time to cross the border again and crash on my bed. Exhausted but satisfied.
