I'm not a fan of Deno's security model (2024)
this has been bothering me for a while now, so I want to write down my thoughts so I can get it out of my head and move on. we’re gonna talk about how Deno approaches security, specifically with its permissions system, and why I think this approach is fundamentally insecure and misleading.

Compile-Time Evaluation in the Zig System Programming Language
Zig places importance on the concept of whether an expression is known at compile-time. There are a few different places this concept is used, and these building blocks are used to keep the language small, readable, and powerful.

Church vs. Curry Types
Static vs dynamic typing debates often flounder because the debators see from two different perspectives without knowing it. Learning to identify the two perspectives can calm the discussion. The tension between the two perspectives has led to Gradual Typing and other technologies.

Contracts in Nix
The Nix language lacks a good type system . There are already several configuration languages that provide static and even gradual typing (see, e.g., Cue , Dhall , or Nickel ), but none offer the ability to easily annotate legacy Nix code with types.

An upgrade to attoparsec, Haskell parsing library: more speed, more power
I’m pleased to introduce the third generation of my attoparsec parsing library. With a major change to its internals, it is both faster and more powerful than previous versions, while remaining backwards compatible. Comparing to C Let’s start with a speed comparison between the hand-written C code that powers…

Why I still love Perl
At the very beginning, I should probably make it clear that this post is not a declaration of exclusivity in my relationship to Perl. I love programming languages. I first learned to program about the same time I first learned to read (English) and first studied French. My love for programming languages is very much…

A farewell note to a programming language
Do you remember how we first met, back in 2012? I thought your functional approach was fresh, and different. For a while I believed we were made for each other. A first project was a success; on my own I was comfortable with the good parts of you. But as soon as I started working in teams writing Scala, your immense…
