Levels of code in Forth programming (2002)
I had been programming in Fortran and assembler for a number of years when I got my first personal computer. It was exciting. On the first generation PC one had to toggle in a paper tape loader from front panel switches, byte by byte, then start the paper tape reader and then one could output to the led on the front…

Reducers, transducers and core.async in Clojure
This is a whirlwind tour of some of the cool new features that appeared in Clojure in the past few years. I find it fascinating how one good idea (reducers) morphed into another (transducers), and ended up mating with yet another, apparently unrelated concept (concurrent pipelines) to produce some really powerful…

Client-side web programming in Haskell: A retrospective
At the beginning of this decade (2010), a few of us Haskellers were exploring how best to do client-side web programming. We didn’t want to write JavaScript. There’s a surprising number of techniques we tried to avoid doing so. There was work coming from academia and industry. Here’s a history of my own experience in…

Let's Write Some x86-64
…"‘Our speech interposes itself between apprehension and truth like a dusty pane or warped mirror. The tongue of Eden was like a flawless glass; a light of total understanding streamed through it. Thus Babel was a second Fall.’ And Isaac the Blind, an early Kabbalist, said that, to quote Gershom Scholem’s translation…

One-pass Compiler
A one-pass compiler emits assembly (or binary code) right during parsing, without creating an intermediate representation, such as an AST. This is a rare technique that was used back in the days when computer memory was scarce. This limited both the language features that were possible and the quality of the produced…

Parsing integers quickly with AVX-512
If I give a programmer a string such as "9223372036854775808" and I ask them to convert it to an integer, they might do the following in C++: std::string s = .... uint64_t val; auto [ptr, ec] = std::from_chars(s.data(), s.data() + s.size(), val); if (ec != std::errc()) {} // I have an error ! // val … Continue reading…

How to Create Your Own Git Server
Although I'm a happy (also paying) user of GitHub's offerings, there are times when I prefer to host a private repository on a server I control. Setting up your own Git server can be useful if you're isolated from the public internet, if you're subject to inflexible regulations, or if you simply want features…
