Let’s go for my web review for the week 2024-47.

The Big Data Center Water Problem

Tags: tech, hardware, ecology, economics, energy, water

We always think about the energy consumption, but large data centers gobble billion liters of water too. This would need to be improved.

Bridgy Fed

Tags: tech, social-media, fediverse, tools

You’re on the fediverse and you want to reach out bluesky users? This might be the right tool for you (unclear if it’ll scale yet though). At least if and when Bluesky turns bad, people will know where to reach friends next.

Why Not Bluesky

Tags: tech, social-media, business, politics

Excellent post showing reasons to be skeptical about Bluesky’s future. Despite all their likely sincere claims I don’t see how they’ll escape enclosure and enshittification when their sketchy VCs will want to see money back.

Elon Musk’s X is hemorrhaging users to Threads and Bluesky

Tags: tech, social-media, politics, twitter

Sad to see people predominantly jumping from Twitter to other tech moguls walled gardens. This feels more and more like a missed opportunity for the fediverse. That said I’m amazed at how efficient Musk has been at killing the network effect of his platform. This proves it’s actually doable.

A computational analysis of potential algorithmic bias on platform X during the 2024 US election

Tags: tech, social-media, politics, twitter

This is what we get for refusing to regulate social media and for not auditing their algorithms. Their owners can game and bias the platforms as they see fit for their own gains. They became massive forces of manipulation in the process.

ChatGPT is Slipping

Tags: tech, ai, machine-learning, gpt, vendor-lockin

Good reminder that models shouldn’t be used as a service except maybe for prototyping. This has felt obvious to me since the beginning of this hype cycle… but here we are people are falling in the trap today.

FireDucks : Pandas but 100x faster

Tags: tech, python, performance, pandas, data, data-science

OK, the numbers are indeed impressive. And it’s API is fully compatible apparently, looks like a good replacement if you got Pandas code around.

Retrofitting spatial safety to hundreds of millions of lines of C++

Tags: tech, c++, security

Will we see more deployments of C++ standard library with bound checking by default? It definitely looks tempting.

Upcoming hardening in PHP

Tags: tech, php, security

Seeing the amount of PHP code open on the internet, it’s indeed important to harden the runtime (at long last).

Bye for now!

We have updated Krita for Android and ChromeOS in the Google Play Store to 5.2.8, an Android/ChromeOS-only emergency release. This release fixes startup problems that happened on some devices with 5.2.6. Krita 5.2.8 for Android is now available both for beta-track users as well as in the "stable" release track. Note, however, that we still recommend treating Krita on Android as a beta release that might have bugs that impair your work, as well as a user interface that is not optimized for touch devices.

Dear digiKam fans and users,

After five months of active maintenance and many weeks triaging bugs, the digiKam team is proud to present version 8.5.0 of its open source digital photo manager.

Generalities

More than 160 bugs have been fixed and we spent a lot of time contacting users to validate changes in pre-release versions to confirm fixes before deploying the program to production.

Application internationalization has also been updated. digiKam and Showfoto are released with 61 different languages for the graphical interface. Go to the Settings/Configure Languages dialog and change the localization as you want. digiKam needs to be restarted to apply the changes. If you want to contribute to the internationalization of digiKam, please contact the translator teams, following the translation how-to. The statistics about translation states are available here.

When Machine Learning Tells the Wrong Story

Tags: tech, cpu, hardware, security, privacy, research

Fascinating research about side-channel attacks. Learned a lot about them and website fingerprinting here. Also interesting the explanations of how the use of machine learning models can actually get in the way of proper understanding of the side-channel really used by an attack which can prevent developing actually useful counter-measures.

Opposite of Cloud Native is?

Tags: tech, cloud, complexity, vendor-lockin, self-hosting

Definitely a good post. No you don’t have to go all in with cloud providers and signing with your blood. It’s often much more expensive for little gain but much more complexity and vendor lock in.

Booleans Are a Trap

Tags: tech, design, type-systems

Avoiding boolean parameters in library APIs should be a well known advice by now. Still they should probably be avoided when modeling domain types as well.

Complex for Whom?

Tags: tech, design, complexity

Good musing about complexity. Very often we need to move it around, the important question is where should it appear. For sure you don’t want it scattered everywhere.

What makes concurrency so hard?

Tags: tech, distributed, complexity

Interesting reasoning about what is hard in systems with concurrency. It’s definitely about the state space of the system and the structure of that space.

Bye for now!

KDE Gear is our release service for many apps such as mail and calendaring supremo Kontact, geographers dream Marble, social media influencing Kdenlive and dozens of others. KDE needs you to test that your favourite feature has been added and your worst bug has been squished.

You can do this with KDE neon Testing edition, built from the Git branches which get used to make releases from. You can download the ISO and try it on spare hardware or on a virtual machine to test them out.

But maybe you don’t want the faff of installing a distro. Containers give an easier way to test thanks to Distrobox.

Install Distrobox on your normal computer. Make sure Docker or podman are working.

Download the container with

distrobox create -i invent-registry.kde.org/neon/docker-images/plasma:testing-all

Then start it with
distrobox enter all-testing
And voila it will mount the necessary bits to get Wayland connections working and keep your home directory available and you can run say

kontact

and test the beta for the mail app.

Earlier this year I had the pleasure of visiting the KDE Akademy 2024 in Würzburg. It had been a few years since my last visit to Akademy and it was great to see old friends and meet new ones. Besides socializing, my main task was to talk to as many KDE people as possible about the privact project and its integration into KDE. Knowing the KDE community, not surprisingly this resulted in lots of interesting discussions.

Most importantly, I gave a talk about the current state of privact’s integration with KUserFeedback. If you missed it, here is the recording:

As a follow-up, we had 2 BoFs on Monday to discuss the next steps. Felix was kind enough to join me to provide more technical developer insights than I can give.

As a first teaser for you: In the short term, the privact approach will allow KDE to do proper user research, thereby enabling us to do data-driven UX without compromising user privacy. In the longer term, privact aims to restore digital privacy for everyone, even outside of KDE, even outside of FLOSS. You can learn more in upcoming posts or on the privact homepage.

The individual feedback on the privact approach during Akademy was very good, which is why we now want to start communicating with the larger KDE community. So this post is not only to report about my attendance at Akademy, but also to start blogging again on Planet KDE and to check if the aggregation works.

Hello World Planet KDE!

It was once said over the grapevine that: "Our C++ API documentation has some issues, our QML API documentation has a lot of issues."

And it was true, but that is to change soon! As you might know, there is an ongoing effort to port our documentation from Doxygen to QDoc, and you can help with that.

This is a task that has been adopted by the Streamlined Application Development Experience championed by Nicolas Fella and Nate Graham as part of the KDE Goals initiative.

We would like to invite you to join our porting sprint effort to finish this task. On November 14th at 1PM UTC, we'll be hanging out in the Matrix room working on this. Hope to see you there.

Some prerequisites:

• Ability to use a terminal
• Extra disk space (30GB minimum)
• Some familiarity with APIs

Check out the instructions prepared by Thiago Sueto on how to get started porting a project to QDoc.

Welcome to the @Krita-promo team's October 2024 development and community update.

Development Report

Android-only Krita 5.2.8 Hotfix Release

Krita 5.2.6 was reported to crash on startup on devices running Android 14 or later. This was caused by issues with an SDK update required for release on the Play Store, so a temporary 5.2.7 release reverting it was available from the downloads page only.

However, the issue has now been resolved and 5.2.8 is rolling out on the Play Store. Note that 5.2.8 raises the minimum supported Android version to Android 7.0 (Nougat).

Community Bug Hunt Started

The development team has declared a "Bug Hunt Month" running through November, and needs the community's help to decide what to do with each and every one of the hundreds of open bug reports on the bug tracker. Which reports are valid and need to be fixed? Which ones need more info or are already resolved?

Read the bug hunting guide and join in on the bug hunt thread on the Krita-Artists forum.

It’s been a minute!

We have been hard at work making sure our design system keeps moving forward. For the past weeks, we have made significant progress in the space of color creation and icons.

There is also an easter egg in the form of PenPot. Read the rest!

As previously mentioned, we restructured our color palettes to have set color variations at various levels. We will combine those colors into tokens that will be named something like this:

pd.sys.color.red50

Meaning:

• PD: Plasma Design
• SYS: System token (We also have reference tokens and component tokens, .ref. and .com. respectively)
• Color: Token type
• red50: color name + color value

Note that as we follow Material design guidelines for these colors, we have a collection of 100 different color shades for a given color. Depending on the needs of the system or changes in design, we could decide to not use red50 but we would like more intensity. So we would choose red49, or red48, and so on.

The color variable name would change accordingly. This set up would allow designers and developers to understand the kind of token they are working with and it would be the same language for both developer and designer.

In Figma and PenPot, designers have the ability to name tokens however they like. I opted for keeping token names as we are recommending them for the Plasma system. That way there is good consistency.

This week, we consolidated these colors and we added them to the list of tokens in Figma and PenPot. However, there is still more to be done in the form of documentation for our Plasma developer team. We are still working through it, making sure we are accurate in the request for development.

Additionally, this week we had the pleasure to meet with Pablo Ruiz, CEO at PenPot. Mike, one of our team members met Pablo recently and spoke of our Plasma Next project. This led to a meeting to discuss the needs that our team currently has for developing a design system.

The team at PenPot is excited to partner with our KDE team and the Plasma Next initiative. They have generously offered a few resources to help.

This couldn’t come at a better time as very recently we have been hitting gaps in our team knowledge when it comes to developing design systems. This process is a first for our desktop system and we want to get it right. With the help of the PenPot team and the changes they are making to the application, this should be easier.

As such, we also decided to request prioritization for some of our tickets that would allow us to set up and migrate our Figma assets into PenPot and eventually, share these with the community at large.

Today, we are not close to releasing a full design system for others to use, but we are making good progress. Stay tuned!

We also moved into the process of editing 16px icons. Given that we already have new icons in the 24px collection that we can leverage, we cut the design time in half or more. We don’t have to brainstorm new icons, we mostly just have to edit the 24px icon and adapt it to a 16px version. This work just barely started but we are making good progress.

One area that is still up in the air is our colorful icons. Given we edited the monochrome icons, this calls for editing colorful icons as well. We have received many suggestions on what kind of colorful style we should follow. I would like to extend that invitation.

If you have seen or created amazing colorful icons and would like to suggest that style for us at Plasma, send us a comment!

That’s it for this week. Good progress so far!
