These are called "cache-timing attacks". In presence of caches, no memory lookup can be guaranteed to be constant time. Any memory lookups that use secret indices are thus not timing-safe, however non-secret indices are OK. See h

They mostly keep releasing the same car under different brands, so the cost for brand differentiation with respect to actual car production is pretty much the same as if it was a single brand. They even add non-Stellantis brands to it, e.g.

Hashing is not the only thing that stops git from being useful for large file versioning. For this purpose, splitting files into chunks using a rolling hash (similar to how git packs, rsync, tarsnap or IPFS) would work better. This again do

Most git objects are tiny files, so internal tree-based parallelization won't bring much compared to file parallelization (git is a hash tree itself, with variable-length leaves). SHA256 is actually a lot faster on modern CPUs due to

Why do you need a longer article for such a simple idea?

Another cool trick: Acorn image editor can take screenshots of the whole desktop environment (all windows, menus, etc) and put them in separate layers. You can then rearrange them as you wish.

While Electron had a huge impact, before Atom team developed atom-shell (which became Electron), there was NodeWebkit (now nw.js). I actually shipped a Windows app written with it and Angular.js, without using Windows for development or bui

Indeed! For one of the my images, which had lots of non-linear gradients and shadows (an app icon), an optimized (with the best algorithm using ImageOptim) 457 KB PNG got compressed to 36 KB WebP (lossless, of course).

Yeah, sorry for the lack of keystokes. I usually use ScreenFlow which also has this feature, but for this one I used LICEcap.

Finally! So many outliners think of each node as a separate text field and add node movements on top. This one gets it. Great work, Jesse!

You can also drop the new line character by using echo -n, which gives 82 bytes :)

JXL without container has a very short header, which is nice. WebP is 38 bytes, and is already supported by browsers. 00000000 52 49 46 46 24 00 00 00 57 45 42 50 56 50 38 4c |RIFF$...WEBPVP8L| 00000010 18 00 00 00 2f ff c0 3f 00
