The case for frameworks
I push back on Alex Russell's "Market for Lemons" post blaming JS frameworks and their advocates for poor mobile web performance. Developers aren't stupid or deceived: React dominates because of rational economics. Frameworks save developer time, enable hiring, and compound via ecosystems. Better frameworks, not fewer…

An interactive explanation of quadtrees (2014)
The space is divided into four rectangles . Each of those rectangles is divided such that it contains a maximum of four children . Each child is either a point or a smaller rectangle.

The bottom emoji breaks rust-analyzer
Some bugs are merely fun. Others are simply delicious! Today’s pick is the latter. Reproducing the issue, part 1 (It may be tempting to skip that section, but reproducing an issue is an important p...

<3 Deno
Deno is a relatively new JavaScript runtime. I find it quite interesting and aesthetically appealing, in-line with the recent trend to rein in the worse-is-better law of software evolution. This post explains why.

Algorithmic Trading: A Practitioner’s Guide
I really enjoyed reading Algorithmic Trading: A Practitioner’s Guide by Jeffrey M. Bacidore. Before starting, I imagined it would cover various strategies for trading in the markets, along th…

How to create portable Linux binaries
Creating application binaries for Linux that run on a wide range of distributions is a bit tricky, as different distributions ship different versions of various system libraries. These are usually backwards compatible, but not forwards compatible, so programs linked against older versions of the libraries also work…

Let's write a setjmp
Yesterday I wrote that setjmp is handy and that it would be nice to have without linking the C standard library. It’s conceptually simple, after all. Today let’s explore some differently-portable implementation possibilities with distinct trade-offs. At the very least it should illuminate why setjmp sometimes requires…

My review of the C standard library in practice
In general, when working in C I avoid the standard library, libc, as much as possible. If possible I won’t even link it. For people not used to working and thinking this way, the typical response is confusion. Isn’t that like re-inventing the wheel? For me, libc is a wheel barely worth using — too many deficiencies in…

How a Zig IDE Could Work
Zig is a very interesting language from an IDE point of view. Some aspects of it are friendly to IDEs, like a very minimal and simple-to-parse syntax (Zig can even be correctly lexed line-by-line, very cool!), the absence of syntactic macros, and ability to do a great deal of semantic analysis on a file-by-file basis…

Can sanitizers find the two bugs I wrote in C++?
A few days ago I published a short post about two bugs I wrote while developing the C++ external scanner for my TLA⁺ tree-sitter grammar. Reactions were mixed! Many people were supportive, but there were of course the usual drive-by claims by developers that the bugs were trivial, they would’ve found & fixed them…

Crafting container images without Dockerfiles
Last month I have been developing a Rust tool to create container images from Conda environments, without going through Docker. It was a wild trip down the rabbit hole of OCI images, so I thought I’d share part of the adventure here. Enjoy! But why? If you are used to building container images, you might be asking…
