#glibc — Public Fediverse posts

I am not familiar with it and how it is implemented in glibc, but out of curiosity I am wondering why they removed support for memory tagging on aarch64. The corresponding commit says that it was somehow broken: https://sourceware.org/git/?p=glibc.git;a=commit;h=70be9819b5eb7ed0050cffb45113332f96f5a55f

Does somebody have a nice link that explains the problem(s) in more detail?

Tim Sweeney arremete contra Gabe Newell tras la subida de precio de Steam Deck: "Graves trastornos en la cadena de suministro de componentes para megayates" https://www.hobbyconsolas.com/videojuegos/tim-sweeney-arremete-contra-gabe-newell-tras-subida-precio-steam-deck-graves-trastornos-cadena-suministro-componentes-para-megayates_6976752_0.html

Todas las consolas han subido de precio. Los WC* consolizados los que más, como Lenovo y MSI. No sé, puestos a criticar yo me metería más con quienes firman contratos de suministro jodiendo a todo el mundo.

A #Wine nunca le sobran fondos ni mano de obra, ni a #Mesa #freedesktop, #Linux, #GCC, #Glibc …

Existe la #LGPL que permite enlazar software privativo. Es la licencia que utiliza la #Glibc.

Así, cosas como las que dijo John #Carmack son erróneas. Ya me dirás qué valor saca #FreeBSD de la #PS5. Si casi no se obtiene nada de #Linux en televisores u otros dispositivos siendo #Copyleft con #GPL.

"The recent discussions around copilot are a good opportunity to say this: I wish I could have licensed the Id source code releases as #BSD. The GPL virality wound up being a net negative, and more value would have come from BSD. My partners would never have gone for it, though."

Почему функции rand и lrand48 из glibc годятся только для Тетриса: о случайных числах всерьёз

Функцию rand из стандартной библиотеки языка Си для генерации псевдослучайных чисел, наверное, не ругал только ленивый. В довольно известном докладе Rand considered harmful рассказывалось о проблемах с переносимостью, ограниченным диапазоном, многопоточностью, качеством и т.п. Иногда в учебниках упоминают о том, что алгоритм в rand может быть не очень качественным, иметь проблемы с младшими битами, периодом, прохождением статистических тестов. Но крайне редко можно увидеть разбор конкретных критериев, выявляющих дефекты генераторов. В этой статье я постараюсь наглядно показать не просто отдельные недостатки rand , lrand48 и random из glibc, но их полную непригодность для каких-либо вычислений в принципе. Также вы увидите превосходство поточных шифров над minstd , линейным конгруэнтным генератором из 1980-х, не только в качестве, но и в производительности.

That's very very BAD in 2026

The only "big" problem in Chi's run was https://www.linuxfromscratch.org/blfs/view/systemd/postlfs/efivar.html

the patch that's needed so it builds clean with glibc 2.43 can be found here

all in all https://linuxfromscratch.org/lfs/view/13.0-systemd-rc1/ seems to be in good shape
