Even more hindsight on Vim, Helix and Kakoune
Oh my… 2023 has been such a trek so far… If you have missed my previous article about my thoughts about editors and development platforms, I think it’s probably the moment to have a look at it.

Interviewing for a JavaScript Job
“The Carpenter” was a JavaScript programmer, well-known for a meticulous attention to detail and love for hand-crafted, exquisitely joined code. The Carpenter normally worked through personal referrals, but from time to time a recruiter would slip through his screen. One such recruiter was Bob Plissken. Bob was…

A production bug that made me care about undefined behavior
Years ago, I maintained a big C++ codebase at my day job. This product was the bread winner for the company and offered a public HTTP API for online payments. We are talking billions of euros of processed payments a year.

A lock-free, concurrent, generic queue in 32 bits
While considering concurrent queue design I came up with a generic, lock-free queue that fits in a 32-bit integer. The queue is “generic” in that a single implementation supports elements of any arbitrary type, despite an implementation in C. It’s lock-free in that there is guaranteed system-wide progress. It can…

Notes on Idris (2017)

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…

Thus Babel was a second Fall.’ And Isaac the Blind, an early Kabbalist, said that, to quote Gershom Scholem’s translation…
