Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Hello, voici un petit guide pour ceux qui aimeraient savoir comment gérer des évènements autres que "KeyRelease", "ButtonPress" (souris), "Expose" et "Loop".

En effet, la minilibx ne dispose que des fonctions permettant de gérer ces évènements. Or ils ne sont pas suffisants pour faire des programmes évolués (cool un Wolf3D qui nécessite que j'appuie plusieurs fois sur la touche HAUT pour avancer!)

En fait, il faut pour cela regarder dans le code de la MinilibX et voir comment sont gérés les évènements envoyés par le serveur X.

Si vous voulez en savoir plus, regardez le fichier "mlx_int_param_events.c" ;)

Mais revenons au sujet principal: Comment gérer d'autres évènements?

The nixos.org website suggests to use:

sh <(curl -L https://nixos.org/nix/install)

For macOS on Intel (x86_64) or Apple Silicon (arm64) based macs, we need to use

sh <(curl -L https://nixos.org/nix/install) --darwin-use-unencrypted-nix-store-volume
