Interesting piece covering: how a memory allocator works, why it can be slow, how to use it the best way possible and how to pick an allocator for your project.

Very thorough analysis on the kind of web frontend performances you can expect for most people on mobile. Since we basically need to reduce the footprint of such frontends to make this sustainable again this is a very welcome article.

Obviously didn't read it all but this is a very large knowledge repository of practices from many companies one can get inspired by to work on Site Reliability Engineering. It is especially comprehensive since it's not only about technical tips but also deals with hiring, team building and culture (which is almost as important if not more).
