看过 还有明天 🌕🌕🌕🌕🌕
完全没看电影背景就去看了，本来以为是部老的黑白电影，可是一些运镜、配乐和精气神又很有现代感，看了下才发现是去年的，本来一个很悲伤痛苦的背景确拍出了很多幽默感，也是难得在电影院又有一波波共同笑声，既没有让当下的权力和痛苦垄断主题，又建构了自己的世界，剧情结构和表现形式上很多聪明的巧思和设计，结尾本来一直担忧别又是走入俗套的循环，结果给出了超出预期的回答，开头看到名单自导自演，就觉得原创性不会差，果然如此。
非常好的观影体验，这种温柔又坚定，有策略又有力量的体验确实是女性导演们作品最大的不同，力荐去影院观看

#snac is a pretty cool #fediverse #activitypub server software!

Super lightweight, no database, easy to set-up.

I will not replace my main #mastodon instance with it, but i really have some other use cases for it, for example some bots or so.

And from what I saw, the code also is pretty nice to learn things from it. (me, a c programming noob)

Edit: Totally dumb of me to NOT post the Git repo in the first place 🤦‍♂️

Hello, #C'estPasPourMoi #C'estPourUneCopine

[Edit] pleins de réponses de vous toutes. Vous êtes super. Merci !

Une copine travaillant dans une grosse boîte se voit demandée d'installer Microsoft Authenticator sur son tel perso en vue de pouvoir s'authentifier sur son futur PC.

Elle a envie de s'y opposer. Ça semble d'ailleurs évident.

Peut-elle s'y opposer, comment s'y opposer ?

#C
经常在一些厂家SDK看到有变量define在header里
为了防止重复linker还特意加了
#ifndef __XXXXX_C
extern .....;
#else

#endif
这是为了什么呢

Just switched to mtm (Micro Terminal Multiplexer) a suckless-style terminal multiplexer that does ONE thing: split panes. No sessions, no bloat, just ~1000 lines of clean C code.

The codebase is surprisingly readable and well-organized... unlike larger projects where you get lost in abstraction layers, mtm's simplicity makes it an excellent study resource for learning C.
You can actually understand the entire program flow in a reasonable amount of time.

Bonus: there's already a SlackBuild available, so Slackware users can integrate it seamlessly into their system without manual compilation headaches.
If you want tmux functionality without tmux complexity, check it out.

'hello world' i would say.

some of you might already know me, but for those who dont

i'm radhitya (al1r4d in the other place) and interested in #linux, #openbsd, #golang, #c, low-level programming, #esp32, #arduino, and #selfhosting.

i think this should be enough to introduce myself.
