Hacker News now runs on top of Common Lisp
Hacker News was written in the Arc lisp dialect, a dialect created by Paul Graham. Arc was implemented on top of Racket, but that has now changed. HN runs on top of SBCL since (at least) September of 2024.But why? For performance reasons. I recently noticed that Hacker News no longer uses paging for long threads. In…

Why is Zig so cool?
I can’t think of any other language in my 45 years long career that surprised more than Zig . I can easily say that Zig is not only a new programming language, but it’s a totally new way to write programs, in my opinion. To say it’s merely a language to replace C or C++, it’s a huge understatement.

Zig's comptime is bonkers good
Programming has obvious abilities to increase productivity through automated manipulation of data. Metaprogramming allows code to be treated as data, turning programming’s power back onto itself. Programming close to the metal has perhaps the most to gain from metaprogramming as high level concepts need to be mapped…

Dijkstra On the foolishness of "natural language programming"
Since the early days of automatic computing we have had people that have felt it as a shortcoming that programming required the care and accuracy that is characteristic for the use of any formal symbolism. They blamed the mechanical slave for its strict obedience with which it carried out its given instructions, even…

Why F#?
If someone had told me a few months ago I’d be playing with .NET again after a 15+ years hiatus I probably would have laughed at this.1 Early on in my career I played with .NET and Java, and even though .NET had done some things better than Java (as it had the opportunity to learn from some early Java mistakes), I…
