This week
- 2025 Clojure+ is a project to improve Clojure stdlib. Cyrillic version of Internet Explorer logo. Because it’s iconic. 2024 Squint is a light-weight dialect of ClojureScript with a compiler and standard library. “The idea is that when you squint, it still looks like CLJS”....

- I had a quick pair programming session with one of my colleagues. Can you imagine that Claude Code doesn’t need to be your only coding buddy? The validation rules needed a little tweak, so here is the piece of code I typed, and below is the version suggested by my friend....
- Having access to multiple parallel CPU cores isn't a new thing by any means, people have been programming in parallel for half a century now, but recent years we've found ourselves at an inflection point. Moore's law is dying, beefy single cores are no longer keeping up. Modern...

- There is a compounding value in being honest...
- Mathias Verraes writes about the relationship between Domains and Bounded Contexts in Domain-Driven Design. It’s a common myth that there should always be a 1:1 relationship between them, but although it’s sometimes the case, deeper modeling often exposes a more interesting...
- Hidden benefits of undefined behavior I was reviewing some code at work, and something jumped at me when reading some arithmetic: static inline int64_t int32ToDecimal9(int32_t i) { return i * 1000000000; } If you’ve had the good fortune of dealing with C or C++ for extended...
- Last time, we explored common methods of sequencing effects into little programs. If you haven't read it yet, I'd recommend starting with that, but you can probably manage without it if you insist. We examined Applicatives, Monads, and Selective Applicatives, and each of these...
- Is Systems Research Really Just About Making Numbers Bigger? The Barbarian F.C. of systems research would be pretty cool. Lots of folks online have been talking about Barbarians at the Gate: How AI is Upending Systems Research by Cheng, Liu, Pan, et al this week. Maybe...

- In November of 2024 I wrote a blog post titled "Is Python Really That Slow?", in which I tested several versions of Python and noted the steady progress the language has been making in terms of performance. Today is the 8th of October 2025, just a day after the official release...
- A Norm of a vector \(\vec{v}\) describes the magnitude or size of a vector. It is usually denoted as \(||\vec{v}||\). There are a few common norms worth discussing. Eucledian Norm (L2 Norm) Let's consider a vector v = [3, 4] we can calculate the Eucledean norm as,...
- A bytecode compiler and VM for a Forth-like language....
- Locality, and Temporal-Spatial Hypothesis Good fences make good neighbors? Last week at PGConf NYC, I had the pleasure of hearing Andres Freund talking about the great work he’s been doing to bring async IO to Postgres 18. One particular result caught my eye: a large difference...
- I like many others initially dismissed Odin as that language that was primarily intended for game development. It took me a moment or should I say many moments to realize just how stupid that notion was......
- Holly molly, September was hectic, mostly good and definitely memorable. Family came over for a visit from Poland, we got married, we travelled to northern Italy, and the most recent meetup I organised was a huge success. It was intense and I’m ready for a chill and quiet...
- Concurrent-safe operations without explicit synchronization....
- Writing out C++ module files and importing them is awfully complicated. The main cause for this complexity is that the C++ standard can not give requirements like "do not engage in Vogon-level stupidity, as that is not supported". As a result implementations have to support...
- Consistent approach to hashing and equality checks in custom collections....

- Been quiet around here! I’ve been putting almost all of my writing time into Logic for Programmers and my whole brain is book-shaped. Trust me, you do not want to read my 2000-word rant on Sphinx post-build LaTeX customization. But I spent the past week in a historical rabbit...
- One of my favourite requests for help online comes from the shibboleth-users group, where someone Japanese used machine translation to ask about the following problem: At often, the goat-time install a error is vomit. To how many times like the wind, a pole, and the dragon?...
- Allow the new built-in to be called on expressions....
