GNOME and KDE to co-host the Linux App Summit in November

Thursday 1st of August 2019 06:37:20 PM
The GNOME and KDE projects are teaming up to host the Linux App Summit (LAS) that will be held in Barcelona, November 12-15. "LAS is the first collaborative event co-hosted by the two organizations since the Desktop Summit in 2009. Both organizations are eager to bring their communities together in building an application ecosystem that transcends individual distros and broadens the market for everyone involved. KDE and GNOME will no longer be taking a passive role in the free desktop sector. With the joint influence of the two desktop projects, LAS will shepherd the growth of the FOSS desktop by encouraging the creation of quality applications, seeking opportunities for compensation for FOSS developers, and fostering a vibrant market for the Linux operating system." The CfP is open until August 31.

[$] An end to implicit fall-throughs in the kernel

Thursday 1st of August 2019 03:06:36 PM
The C switch statement has, since the beginning of the language, required the use of explicit break statements to prevent execution from falling through from one case to the next. This behavior can be a useful feature, allowing for more compact code, but it can also lead to bugs. The effort to rid the kernel of implicit fall-through coding patterns came to a conclusion with the 5.3-rc2 release, where the last cases were fixed. There is a good chance that these fixes will have to be redone in the future, though.

[$] Python and public APIs

Wednesday 31st of July 2019 09:12:22 PM
In theory, the public API of a Python standard library module is fully specified as part of its documentation, but in practice it may not be quite so clear cut. There are other ways to specify the names in a module that are meant to be public, and there are naming conventions for things that should not be public (e.g. the name starts with an underscore), but there is no real consistency in how those are used throughout the standard library. A mid-July discussion on the python-dev mailing list considered the problem and some possible solutions; the main outcome seems to be interest in making the rules more explicit.

[$] KernelShark releases version 1.0

Wednesday 31st of July 2019 04:52:11 PM
It has been the better part of a decade since the last KernelShark article appeared here; in the interim, the kernel-tracing visualization tool has undergone some major changes. While the high-level appearance is largely similar, the underlying code has switched from GTK+ 2.0 to Qt 5. On July 26, maintainer Steven Rostedt announced the release of KernelShark version 1.0, which makes it a good time to take another peek.

[$] Bounded loops in BPF for the 5.3 kernel

Wednesday 31st of July 2019 04:39:31 PM
BPF programs have gained significantly in capabilities over the last few years and can now perform many useful operations. That said, BPF developers have had to work around an annoying limitation until recently: they could not use loops. This restriction was recently lifted by a patch set from Alexei Starovoitov that was merged for Linux 5.3. In addition to adding support for loops, it also greatly decreases the load time of most BPF programs.

Collabora: Moving the Linux desktop to another reality

Tuesday 30th of July 2019 07:43:27 PM
The Collabora blog announces some ongoing work to integrate Linux desktop environments with head-mounted displays. "In contrast to these approaches xrdesktop aims to integrate into existing Linux desktop environments, eliminating the necessity of running a dedicated compositor for only VR and thus making it usable in current setups. For our initial release, we focused on integration in the most popular Linux desktops, GNOME and KDE, but xrdesktop is designed to be integrated into any desktop. This can be done with Compiz-like plugins as for KWin or patches on the compositor in the case of GNOME Shell. This integration of xrdesktop into the window managers enables mirroring existing windows into XR and to synthesize desktop input through XR actions."

[$] Darling: macOS compatibility for Linux

Tuesday 30th of July 2019 04:54:56 PM
There is an increasingly active development effort, known as Darling, that is aiming to provide a translation layer for macOS software on Linux; it is inspired in part by Wine. While Darling isn't nearly as mature as Wine, contributors are continuing to build out capabilities that could make the project more useful to a wider group of users in the future.

Subscribers can read on for a look at Darling from this week's edition.

Kernel prepatch 5.3-rc2

Sunday 28th of July 2019 08:29:36 PM
The 5.3-rc2 kernel prepatch is available for testing. "There are fixes all over, I don't think there's much of a pattern here. The three areas that do stand out are Documentation (more rst conversions), arch updates (mainly because of the netx arm platform removal) and misc driver fixes (gpu, iommu, net, nvdimm, sound ..)".
