Kernel Queue: The Complete Guide On The Most Essential Technology For High-Performance I/O When talking about high-performance software we probably think of server software (such as nginx) which processes millions requests from thousands clients in parallel. Surely, what makes server software work so fast is high-end CPU running with huge amount of memory and a very fast network link. But even the

Published on 2021-04-14. Modified on 2023-02-16. The name SQLite is a nice name, but the "lite" part is misleading, it sounds like it is only useful for tiny things - which is very wrong. SQLite should be named AwesomeSQL, because that is what it is. SQLite is probably the only database you will ever need in most cases. SQLite is a relational database management system contained in a C library. It

I think the Rust language is a big success. When I think back on it I am in awe: so much had to go right to get where we are, and there were so many opportunities to go wrong. It took many tiny miracles for the Rust language to become what it has. Those miracles didn’t happen by accident though: each one was created by a real person, and real people orchestrated them to become something great. The
As an economist I am not happy about going into having strong views on the causes of why people die from Covid19, but at least I can have a look at correlations.

the short of it is: they’re cool for appending notes from automated systems (like ticket or build systems) but not really for having interactive conversations with other developers (at least not yet) – Scott Chacon, GitHub.blog, Aug. 2010 Git notes are almost a secret. They’re buried by their own distressing usability. But git notes are continually rediscovered by engineers trying to stash metadat
07 Jul, 2022 I figured I'd kick off my new blog with the most click baity thing I could think of. I suspect any developer reading this is aware of the DRY principle because it is just so ubiquitous. If not though, you just need to know that it stands for "Don't Repeat Yourself" and is generally invoked when advising people to not copy and paste snippets of code all over the place and instead conso
