»The Linux From Scratch community announces the release of LFS Version 11.0. The reason for the major release number increment is that this version no longer uses the "split-user" system. That is, like most current distributions, /bin
is a symbolic link to /usr/bin
. Likewise, /lib
and /sbin
are both symbolic links to their /usr
counterparts. «
This post explains the rationale behind the decision to switch from Debian to Arch Linux for SteamOS 3.0.
»Some of you have noticed the past few weeks and months that
a serious attempt to bring a second language to the kernel was
being forged. We are finally here, with an RFC that adds support
for Rust to the Linux kernel.«
Yes, running unsupported, unpatched servers on the Internet is a bad idea.
Buildroot is a simple, efficient, and easy-to-use tool to generate embedded Linux systems through cross-compilation.
The first stable kernel release for 2021 includes an AMD performance regression fix, new hardware support, and filesystem improvements.

This guide provides extensive information on hardening Linux.
Linux 5.10 is released. It is an LTS release and will receive support over the next 5 years. Amongst the many updates and fixes are the performance tuning of Btrfs and EXT, better RISC-V support, and enhancements for BPF programs.
Why the NetworkManager dracut module brings better integration between networking in the initrd and NetworkManager running in the real root filesystem.
The author describes his experience with his transition from macOS to NixOS.
BPF originally stood for Berkeley Packet Filter, but has been extended in Linux to become a generic kernel execution engine, capable of running a new type of user-defined and kernel-mode applications.

After 25 months of development the Debian project is proud to present its new stable version 10 (code name "buster"), which will be supported for the next 5 years thanks to the combined work of the Debian Security team and of the Debian Long Term Support team.
Unikernels have demonstrated enormous advantages over Linux in many important domains, causing some to propose that the days of Linux’s dominance may be coming to an end. On the contrary, we believe that unikernels’ advantages represent the next natural evolution for Linux, as it can adopt the best ideas from the unikernel approach and, along with its battle-tested codebase and large open source community, continue to dominate. In this paper, we posit that an up- streamable unikernel target is achievable from the Linux kernel, and, through an early Linux unikernel prototype, demonstrate that some simple changes can bring dramatic performance advantages.
