Manjaro 24.0 released

6 óra 47 perc óta

Version 24.0 of the Arch-based Manjaro distribution is now available with the 6.9 kernel, GNOME 46, Xfce 4.18, and an update to the Pamac package installer. This is also the project's first release with KDE Plasma 6:

The Plasma edition comes with the latest Plasma 6.0 series and KDE Gear 24.02. It brings exciting new improvements to your desktop.

With Plasma 6, KDE's technology stack has undergone major upgrades: a transition to the latest version of application framework, Qt, and an improved graphics platform when Wayland is used. These changes are as smooth and unnoticeable to the users as possible. You will see the same familiar desktop environment that you know and love. But these under-the-hood upgrades benefit Plasma's security, efficiency, and performance, and improve support for modern hardware. Thus Plasma delivers an overall more reliable user experience, while paving the way for many more improvements in the future.

The project also offers minimal install images with the 6.6 LTS and 6.1 LTS kernels to support older hardware.

[$] Portable LLMs with llamafile

9 óra 5 perc óta

Large language models (LLMs) have been the subject of much discussion and scrutiny recently. Of particular interest to open-source enthusiasts are the problems with running LLMs on one's own hardware — especially when doing so requires NVIDIA's proprietary CUDA toolkit, which remains unavailable in many environments. Mozilla has developed llamafile as a potential solution to these problems. Llamafile can compile LLM weights into portable, native executables for easy integration, archival, or distribution. These executables can take advantage of supported GPUs when present, but do not require them.

Demise of Nagle's algorithm (RFC 896 - Congestion Control) predicted via sysctl

16 óra 14 perc óta
Is the classical TCP congestion control mechanism known as Nagle's algorithm (RFC 896 - Congestion Control) headed for the scrap heap of history?

A recent post on tech@ titled Add sysctl to disable Nagle's algorithm (RFC 896 - Congestion Control) from Job Snijders (job@) with a patch to implement the disabling sysctl indicates that some at least think that deprecation is in order.

The message leads in,

List: openbsd-tech Subject: Add sysctl to disable Nagle's algorithm (RFC 896 - Congestion Control) From: Job Snijders <job () openbsd ! org> Date: 2024-05-13 18:41:55 Dear all, Back in the early 1980s, a suggestion was put forward how to improve TCP congestion control, also known as "Nagle's algorithm". See RFC 896. Nagle's algorithm can cause consecutive small packets from userland applications to be coalesced into a single TCP packet. This happens at the cost of an increase in latency: the sender is locally queuing up data until it either receives an acknowledgement from the remote side or sufficient additional data piled up to send a full-sized segment.

Linux Plumbers Conference: Update on the Microconference situation

1 nap 5 óra óta

Unfortunately we still do not know the total cost of the 4th track yet. We are still in the process of looking at the costs of adding another room, but we do not want to delay the acceptance of topics to Microconferences any further. We have decided to accept all pending Microconferences with one caveat. That is, we are not accepting the rest as full Microconferences. The Microconferences being accepted now will become one of the following at Linux Plumbers 2024:

  • A full 3 hour Microconference
  • A 1 and a half hour Microconference (Nanoconference)
  • A full 3 hour Microconference but without normal Audio/Video

That last one is another option we are looking at. The main cost to having a 4th track is the manned AV operations. But we could add the 4th track without normal AV. Instead, these would get a BBB room where an Owl video camera (or the like) and a Jabra speaker will be in place. The quality of the AV will not be as good as having a fully manned room, but this would be better than being rejected from the conference, or having half the time of a full microconference.

Even with a 4th track, two still need to become Nanoconferences.

In the mean time, we will be accepting the rest of the Microconferences so that they can start putting together content. How they are presented at Linux Plumbers is still to be determined.

Note that this also means we will likely be dropping the 3 free passes that a Microconference usually gets down to only 2 passes.

The accepted Microconferences (as full, half or no A/V) are:

  • Sched_ext
  • Containers and Checkpoint/Restore
  • Confidential Computing
  • Real-Time
  • Build Systems
  • RISC-V
  • Compute Express Link
  • X86
  • VFIO/IOMMU/PCI
  • System Boot and Security
  • Zone Storage
  • Internet of Things
  • Embedded
  • Complex Cameras
  • Power Management and Thermal Control
  • Kernel <-> Userspace/Init/System Management Boundaries and APIs

[$] Some 6.9 development statistics

1 nap 6 óra óta
The 6.9 kernel was released on May 12 after a typical nine-week development cycle. Once again, this is a major release containing a lot of changes and new features. Our merge-window summaries (part 1, part 2) covered those changes; now that the development cycle is complete, the time has come to look at where all that work came from — and to introduce a new and experimental LWN feature for readers interested in this kind of information.

[$] Managing expectations with a contributions and credit policy

1 nap 8 óra óta
Maintainers of open-source projects sometimes have disagreements with contributors over how contributions are reviewed, modified, merged, and credited. A written policy describing how contributions are handled can help maintainers set reasonable expectations for potential contributors. In turn, that can make the maintainer's job easier because it can help reduce a source of friction in the project. A guide to help create this kind of policy for a project has recently been developed.
