Writing Small CLI Programs in Common Lisp
I write a lot of command-line programs. For tiny programs I usually go with the typical UNIX approach: throw together a half-assed shell script and move on. For large programs I make a full Common Lisp project, with an ASDF system definition and such. But there's a middle ground of small ish programs that don't…

I wrote one of the fastest DataFrame libraries
At the time of writing this, the coronavirus has been in our country for a year, which means I have been sitting at home for a very long time.

Speed of Rust vs. C
The run-time speed and memory usage of programs written in Rust should about the same as of programs written in C, but overall programming style of these languages is different enough that it's hard to generalize their speed. This is a summary of where they're the same, where C is faster, and where Rust is faster.
