Very insightful, thank you! I always wondered about transparent aluminium but I see that it is actually a ceramic and not elemental. https://en.m.wikipedia.org/wiki/Aluminium_oxynitride

It is a good question but the answer may be unsatisfactory: it depends. I think that the popularity of scrum is due to its catch-all nature and the way it sounds reasonable when you explain it to someone, especially a non-developer. Here is

This is huge for embedded rust where cargo Features are used heavily. One of those trial and error things that can be frustrating when learning a new library with missing notes about features.

Just give me a 2K monitor that turns on instantly, doesn’t hunt for sources, consumes less than 20W of power and I’ll be a happy guy. Bonus for having physical buttons to select explicit input sources without delays.

The author desires a simple folder based module system and argues how it would improve compilation times. I do agree although it would be nice to know what flexibility would be lost so the argument could have some weight on the other side.

Seems like using memory mapped files for a write-only load is the sub optimal choice. Maybe I’m mistaken but surely using an append-only file handle would be simpler than changing the behaviour of how memory mapped files are cached like the
