Le finance de l'open source est constamment un challenge

I read only kudos about the ArchWiki

Avec la fin du support de Windows 10, Linux atteint 5% d'utilisations selon StatCounter. À l'opposé, Windows a perdu environ 10% comparé à janvier 2022.

L’autre moteur de Linux, comme en France, est sa compatibilité de plus en plus avancée avec les jeux vidéo, lui permettant même de battre Windows sur certains benchmarks en performance.

Le processus dans ce cas est officialisé: https://github.com/torvalds/linux/commit/102606402f4f5943266160e263c450fdfe4dd981#diff-6c81210e8795b03502471e1435cac0763110f72b823038bd0033eb617c15ab8d

Finalement, c'est le retour à Debian qui a primé.

This specification defines where these files should be looked for by defining one or more base directories relative to which files should be located.

Reading a file is actually slow.

getCurrentThreadUserTime() uses many syscalls because it reads from /proc.
clock_gettime(CLOCK_THREAD_CPUTIME_ID) has only one syscall and a direct function call chain.

The optimisation can be done, but:

1. The kernel policy is clear: don't break userspace
2. It's undocumented anywhere!
3. Author's take: if glibc depends on it, it's not going away.

This is why I like browsing commits of large open source projects. A 40-line deletion eliminated a 400x performance gap. The fix required no new kernel features, just knowledge of a stable-but-obscure Linux ABI detail.

The lessons:

• read the kernel source. POSIX tells what's portable; the kernel source code tells what's possible.
• check the old assumptions: revisiting them occasionally pays off.

Donc selon cette expérience, il serait plus intéressant de faire tourner de vieux programmes windows sur Linux au lieu de Windows, ou des programmes Linux sur Linux.

Lol, à voir les résultats, mais GG WP

Landlock shines when an application has a predictable set of files or directories it needs. For example, a web server could restrict itself to accessing only /var/www/html and /tmp.

The author reminds Linux has security issues on most major distributions and each tools trying to improve the state of securit on Linux has drawbacks: Containerization, Flatpak, Firejail, seccomp, SELinux, AppArmor and Landlock.

Landlock fills a major gap: a simple, self-cotnained unprivileged sandboxing tool.

$XDG_SESSION_TYPE provide the session X11 or Wayland.

There are also three other way.

Gaming on Linux has never been easier and Windows is tiring (OneDrive push, Recall, Cortana and AI, Office 365 subscriptions)

So it took 21 years. Better later than never!
