The Amarok music player project has announced the release of version 3.0, which is codenamed "Castaway". It is the first stable version using Qt 5 and KDE Frameworks 5, and the first stable release since the final Qt-4-based 2.9.0 in 2018. The road to 3.0 has not been a short one. Much of the Qt5/KF5 porting was done in 2015 already, but finishing and polishing everything up has been a slow, sometimes ongoing and sometimes stalled process ever since. 3.0 Alpha was released in February 2021 and has been since used by many people, as have been nightly builds of git master available for various distributions. Now in the past few months, an effort was made to get everything ready for a proper 3.0 release.

Common usecases should work quite well, and in addition to fixing KF5 port related regressions reported in pre-releases, 3.0 features many bugfixes and implemented features for longstanding issues, the oldest such documented being from 2009. However, with more than 20 years of development history, it is likely that not every feature Amarok has been tested thoroughly in the new release, and specifically some Internet services that have changed their API in recent years are not available, at least for now. It might well be that getting them in better state wouldn't require huge effort, however, so if you know your way with Qt and KDE Frameworks and your favourite Internet music service does not work with Amarok 3.0, you are extremely welcome to join in and help!

On April 21, a group of anonymous authors and non-anonymous signatories published a lengthy open letter to the Nix community and Nix founder Eelco Dolstra calling for his resignation from the project. They claimed ongoing problems with the project's leadership, primarily focusing on the way his actions have allegedly undermined people nominally empowered to perform various moderation and governance tasks. Since its release, the letter has gained more than 100 signatures.

Robert McQueen has posted a message from the GNOME Foundation board describing the current financial situation, plans to improve it, and an increase in the size of the board.

The Foundation has a reserves policy which specifies a minimum amount of money we have to keep in our accounts. This is so that if there is a significant interruption to our usual income, we can preserve our core operations while we work on new funding sources. We've now "hit the buffers" of this reserves policy, meaning the Board can't approve any more deficit budgets – to keep spending at the same level we must increase our income.

The only way to obtain STEP from OpenSCAD that I know is an external tool that someone made. It's pretty crazy actually: it parses OpenSCAD's native export, CSG, and issues commands to OpenCASCADE's CLI, OCC-CSG. The biggest issue for me here is that his approach cannot handle transformations that the CLI does not support. I use hull all over the place and a tool that does not support hull is of no use for me.

So I came up with a mad lad idea: just add a native export of STEP to OpenSCAD. The language itself is constructive, and an export to CSG exists. I just need to duplicate whatever it does, and then at each node, transform it into something that can be expressed in STEP.

As it turned out, STEP does not have any operations. It only has manifolds assembled from faces, which are assembled from planes and lines, which are assembled from cartesian points and vectors. Thus, I need to walk the CSG, compile it into a STEP representation, and only then write it out. Operations like union, difference, or hull have to be computed by my code. The plan is to borrow from OpenSCAD's compiler that builds the mesh, only build with larger pieces - possibly square or round.

Not sure if this is sane and can be made to work, but it's pretty fun at least.

The 6.9-rc6 kernel prepatch is out for testing.

Things continue to look pretty normal, and nothing here really stands out. The biggest single change that stands out in the diffstat is literally a documentation update, everything else looks pretty small and spread out.

The 6.8.8, 6.6.29, 6.1.88, and 5.15.157 stable kernels have been released; each contains another set of important fixes.

Update: 6.1.89 was released two days later to fix a build problem in 6.1.88.

Video playback is undeniably one of the most important features in modern consumer devices. Yet, surprisingly, users are by and large unaware of the intricate engineering involved in the compression and decompression of video data, with codecs being left to find a delicate balance between image quality, bandwidth, and power consumption. In response to constant performance pressure, video codecs have become complex and hardware implementations are now common, but programming these devices is becoming increasingly difficult and fraught with opportunities for exploitation. I hope to convey how Rust can help fix this problem.

At the CPU level, a memory model describes, among other things, the amount of freedom the processor has to reorder memory operations. If low-level code does not take the memory model into account, unpleasant surprises are likely to follow. Naturally, different CPUs offer different memory models, complicating the portability of certain types of concurrent software. To make life easier, some Arm CPUs offer the ability to emulate the x86 memory model, but efforts to make that feature available in the kernel are running into opposition.
