#c11 — Public Fediverse posts

🎩✨ Behold the wondrous Solod: because who wouldn't want to jump through hoops to turn #Go into C, while pretending #C11 is the new hotness? 🤹‍♂️ No runtime, no garbage collection, and no sense in converting Go to something it was never meant to be, but hey, at least there's syntax highlighting! 🙃

Самый недооцененный механизм безопасности SSH или почему known_hosts — это не кэш

Каждый, кто работает с SSH, наизусть знает ритуал первого подключения (TOFU) и страшный ворнинг о смене ключей хоста. Но почему в 99% случаев мы просто слепо сносим записи через ssh-keygen -R , превращая важный механизм ИБ в формальность, а known_hosts в бездонный кэш? В этой статье мы приоткроем капот SSH-хэндшейка, поглядим одним глазком на пакет SSH_MSG_KEX_ECDH_REPLY и выясним, почему для проверки идентичности сервера не нужен полноценный SSH-клиент. А в конце наведём порядок в многолетних залежах админского мусора с помощью компактной утилиты на чистом Си. Полюбопытствовать

Every time I am forced to do something with the C11 atomic/fence operations, I am newly amazed at how awful the whole api is and what a disgrace that it has been added to the language - specifically against the design of the language.

Southern Moon and telescope trial

This is the southern end of Earth’s waxing gibbous phase Moon, as imaged late Tuesday night. The heavily-cratered area along the terminator includes Crater Tycho — with a central peak lit by the rising Sun — and the dark circular expanse of Clavius, with the top of its western crater wall extending into the deep shadows of the terminator. We used the old Celestron C11 for this session as we continue to evaluate its performance and condition. We continue to be concerned about whether the telescope’s focus issue is simple collimation or some more serious combination of problems.

The C11 specification from #wg14 is so dreadful, so full of dumb ideas badly explained, as to shock the conscience
#computerscience #programming #Clanguage #c11 #wg14

These are not part of the C standard, rather, they’re part of GNU C. In other words, the Linux kernel source cannot be compiled by a compiler that implements the ISO C standard only (e.g., #C99 or #C11) without the GNU extensions. The #Linux kernel doesn’t compile with “standard C”—it compiles with GNU C.

Коробка багов (взрывается): кроссплатформенное коварство

В сентябре мы рассматривали релиз 86Box v5.0, приуроченный к тридцати годам со дня выхода в розничную продажу Windows 95, и пообещали показать ещё кое-что. О чём мы сознательно умолчали, и почему оставили находку для отдельной статьи? Что осталось в "коробке"?

"Canadians could enjoy the resliency that comes of having a domestic tech and repair sector, and could count on it through pandemics and Trumpian trade-war.

All of that and more could be ours, except for the cowardice and greed of Tony Clement and James Moore and the Harper Tories who voted C-11 into law in 2012.

Everything the "radical extremists" warned them of has come true. It's long past time Canadians tore up anticircumvention law and put the interests of the Canadian public and Canadian tech businesses ahead of the rent-seeking enshittification of American Big Tech.

Until we do that, we can keep on passing all the repair and interop laws we want, but each one will be hamstrung by Moore and Clement's "felony contempt of business model" law, and the contempt it showed for the Canadian people."

Uff! This is a nasty & unexpected #bug in the #C11 specification 😰:

Turns out #Linux moved from C89 to #C11 a couple years back: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=50560ce6a0bdab2fc37384c52aa02c7043909d2c It's quite surprising; I thought they'x upgrade only if GCC dropped support for C89 :D

(I'm catching up on my Pocket archive, can you tell? BTW I still find #LWN the best source of inspiration for good software engineering. Just read some, and you're guaranteed to experience an urge to roll up your sleeves and go hack on something.)

Frama-C's new machdep mechanism allows users to more easily create their own machdeps (machine-dependent configuration files). With a #C11-compatible compiler, it's automatic! Check out our new blog post for more details: https://frama-c.com/2024/01/29/new-machdep.html

(And feel free to ask questions here, we'll try to answer them as best we can.)

@Carl On avait déjà perdu le droit de partager des lien de nouvelles. Bientôt, on ne pourra plus écouter Spotify sans VPN. Bravo, champions! #C11 👏🥳 https://www.noovo.info/nouvelle/ottawa-publie-ses-directives-au-crtc-pour-la-loi-sur-la-diffusion-continue-en-ligne.html

Andrew Coyne very clearly articulates why the Canadian goverment's #C11 #LinkTax and #C18 internet #CanCon bills are actively harmful to Canadians and our access to #journalism and the #internet generally. Certainly we have challenges to face on these issues, but a good start would be not making things worse with misguided and heavy-handed regulations

CRTC establishes new registration requirements arising from Bill C-11 for streaming services worldwide, including video and podcasters. Any service - alone or as a group - generating $10M+ in broadcast revenues in Canada must register by November 29, 2023.

#C11

Watched Aaron Gunn's latest vid "The End of Free Speech in Canada" re Bill #C11, featuring intervus with #Poilievre, Ezra Levant, & #jordanpeterson.

But he expressed his concerns best on a panel at ManningCentre/Canada Strong&Free&Proud bunfest in March when he explained:
"A lot of people get their conservative content from US -Ben Shapiro, Joe Rogan-so they're going to bury all that deep on the algorithm if you're Canadian." #cdnpoli #rightwing
Interesting choice of attire for the promo btw
