Why "Structure and Interpretation of Computer Programs" matters (2011)
In 2011, to celebrate the 150th anniversary of MIT, the Boston Globe made a list of the most important innovations developed there. They asked me to explain the importance of SICP, and this is what I sent them:

I tried Haskell for 5 years
One blogpost style which I find almost completely useless is “I tried Programming Language X for 5 days and here’s how it was.” Most of the time, the first impression is superfici…

Scala – 1 Star – Would Not Program Again
With Scala you feel smart having just got something to work in a beautiful way but when you look around the room to tell your clojure colleague how clever you are, you notice he left 3 hours ago and there is a post-it saying use a Map. Daniel Worthington-Bodart

Three Months of Go, from a Haskeller’s perspective (2016)
This summer I’ve been interning at Pusher , and have been writing a lot of Go. It’s been a bit of a change coming from a Haskell background, so I decided to write up my thoughts now, at the end.

Minimalist C Libraries
In the past year I’ve written a number of minimalist C libraries, particularly header libraries. The distinction for “minimalist” is, of course, completely arbitrary and subjective. My definition in this context isn’t about the library’s functionality being stupidly trivial or even necessarily simple. I’m talking…

Why I Chose Common Lisp
After ~7 years, I was done with Clojure . I was writing a some CLI apps , and I hated how long they took to start up. The community at large seemed not to care about this problem, except for the babashka folks. However, I spent long, hard hours banging my head against native-image and it just wasn't working out. It…

Let's Build a Compiler
Compilers, interpreters, runtimes, and the like can sometimes feel vaguely magical. They take your code, perform complex transformations that you only partially understand, and spit out an executable binary. Clearly, the inner workings of such a beast must contain arcane secrets, not meant for the minds of mortals.

Tilde, My LLVM Alternative
I'm Yasser and I've made it my mission to produce an alternative to LLVM, the current king of compiler backend libraries. I'm calling it Tilde (or TB for tilde backend) and the reasons are pretty simple, i believe it's far too slow at compiling and far too big to be fixed from the inside. It's been 20 years and cruft…

Introducing .NET Standard
Questions? Check out the .NET Standard FAQ. You can find the latest version of the compatibility matrix here. In my last post, I talked about how we want to make porting to .NET Core easier. In this post, I’ll focus on how we’re making this plan a reality with .NET Standard. We’ll cover which APIs we […]

A Tour of the Lisps
2023 seems to have been the year where I "made the rounds" of a number of major Lisps. There were several elements that lead to this. Firstly must have been my exposure to Elixir in 2022, which introduced me to the idea of debugging live systems and "staying in your program". Secondly must have been my chief complaint…
