Why async fn in traits are hard
After reading boat’s excellent post on asynchronous destructors , I thought it might be a good idea to write some about async fn in traits. Support for async fn in traits is probably the single most common feature request that I hear about. It’s also one of the more complex topics. So I thought it’d be nice to do a…

Write Fuzzable Code
“An obvious way to deal with embedded interpreters — which someone must have thought of and tried, but I don’t have any pointers — would be to have an API for teaching the fuzzer how to see coverage of the language being interpreted.”

Everything You Never Wanted to Know About CMake
Just hearing the word CMake is typically enough to make a shiver run down my spine. I’ve been deep in the muck of its behavior and tooling the last few weeks as I finish up a CMake library titled IXM. While the various minutiae of how IXM works, why I wrote it, and all the nice little usage details are definitely for…

Fast Perfect Hashing
A perfect hash function is one that is collision-free. By implication, the hash must be at least as many bytes as the key and the function is theoretically reversible, though not always tractably so. In other words, perfect hashing is a special case of encryption. Because the hash is no smaller than the key, the…

In this article I’ll talk about four different fun tweaks to the concept of a hash table that I made in the process of using hash tables to…

Clojure and Deps.edn: A basic guide
After a rather long break from programming and Clojure I decided give them another go. When it comes to managing Clojure projects, Leiningen is de-facto standard tool. Recently, Clojure CLI tools are becoming more and more popular, though. Switching to yet-another-build-tool doesn't have any pragmatic value, but it's…

Fibers: An Elegant Windows API
The Windows API — a.k.a. Win32 — is notorious for being clunky, ugly, and lacking good taste. Microsoft has done a pretty commendable job with backwards compatibility, but the trade-off is that the API is filled to the brim with historical cruft. Every hasty, poor design over the decades is carried forward forever…

How to use array reduce for more than just numbers
The array reduce method is really powerful. But people often run into trouble as soon as they step beyond the basic examples. Simple things like addition and multiplication are fine. But as soon as you try it with something more complicated, it breaks. Using it with anything other than numbers starts to get really…

Why to use ‘python -m pip’
Fellow core developer and Canadian, Mariatta, asked on Twitter about python -m pip and who told her about that idiom along with asking for a reference explaining it: I learned sometime ago that we should be doing `python -m pip install ...` instead of simply `pip install ...` but now I can'
