I sometimes get asked why I use Perl so much. Am I not a fan of strongly typed functional programming? Yeah, I am. Ask me to write something that is known, for sure , to become a big system and I’ll pick strongly typed functional programming without hesitation. 1 1 And, of course, put me in a team that uses Blub, and…
A short post about a neat little Zig idiom. Consider your average {sum type, variant, tagged union, enum, alt}:
Every March, developers worldwide each try to make a roguelike game in less than 168 hours as part of the 7DRL Challenge . Roguelike games are hard , involving procedural level generation, pathfinding, line-of-sight algorithms, and more dijkstra maps than you can imagine.
I believe the notion that Haskell uses “monads” to enforce purity is rather misleading. It has certainly caused quite a bit of confusion! It’s very much like saying we use “rings to do arithmetic”. We don’t! We use numbers, which just happen to form a ring with arithmetic operations. The important idea is the number …

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…
At Devoxx last week I used the phrase "Scala feels like EJB 2 to me". What was on my mind? Scala For a number of years on this blog I'v...

It took more than ten years of full-time work for Rama to go from an idea to a production system. I shudder to think of how long it would have taken without Clojure. Rama is a programming platform …
This post is a case study of writing a Rust application using only minimal, artificially constrained API (eg, no dynamic memory allocation). It assumes a fair bit of familiarity with the language.
If you aren’t wowed by Python’s super() builtin, chances are you don’t really know what it is capable of doing or how to use it effectively. Much has been written about super() and much of that wri…
One year minus one week ago to the day I published an article announcing the new Scheme implementation I was writing, scheme-rs . Today I am excited to announce that scheme-rs has reached its first version, 0.1.0 . You can check it out at it’s website ( scheme-rs.org , which should be updated to scheme.rs at some…
All my life, my heart has yearned for a thing I cannot name. André Breton, Mad Love
Introduce new interfaces to represent collections with a defined encounter order. Each such collection has a well-defined first element, second element, and so forth, up to the last element. It also provides uniform APIs for accessing its first and last elements, and for processing its elements in reverse order.
Tokenizing the source code input is a great start for our compiler. Now let's turn our attention to parsing the PL/0 grammar. Once we have finished with the parser, the front end of our compiler will be finished and we will have a PL/0 validator. This is a program that can read in PL/0 source code and inform the user…
The other day I posted something silly, and learned some interesting things about raw pointers in Rust.
The Lua programming language is unusual among its peers. It’s a dynamically typed, scripting language with a really small core (100-200kB), but runs efficiently, has far simpler semantics than other similar languages, and is just as old as the giants like JavaScript, Python, and Ruby – first made in a research lab…
This post will describe how I design my programs in Go. I needed this for work, and while I searched for a link, nothing quite fits my coding practices out there. The word “Layered” can pull up some fairly close descriptions, but I want to lay out what I do.
