Curious lack of sprintf scaling
Some days ago I noticed that on a Mac, doing snprintf calls from multiple threads shows curious lack of scaling ( see tweet ). Replacing snprintf with {fmt} library can speed up the OBJ exporter in Blender 3.2 by 3-4 times . This could have been the end of the story, filed under a “eh, sprintf is bad!” drawer, but I…

It doesn’t matter if there is another Linux server…

Vim – Minimal Setup Explained
NOTES: I have grouped the options such that the Boolean ones (read: on/off true/false) come first, then those with a short amount of "flags", and after that the ones with a very long value.

Doing 130MB of IO poorly can be quite a performance hit, even with SSDs! :). Few people seem to understand how memory-mapped IO works. There are no pre-canned tools to observe…

A career ending mistake
As software engineers, we're constantly making detailed, elaborate plans for computers to execute. Isn't it weird that we rarely give a moment's thought to the program for our own careers?
