Depend on abstractions, not on concretions
I’ve been lurking the fish shell for a couple of years now (and the nushell but it is another story for another time). Not so long ago, I decided to try it, and it’s simply… amazing. If I had to state one feature that makes me like to use it, it’ll be the autocompletion, hands down. It’s the first time I just take a…
2024 Update: Part 2 is out! Let’s make a gzipped file and see what’s in it. We’ll keep it simple: just write 8 ‘a’s to a file. $ echo "aaaaaaaa" > test.out $ xxd test.out 00000000: 6161 6161 6161 6161 0a aaaaaaaa. As we can see, our file is 9 bytes long. We have 8 ‘a’ bytes written, plus a Line Feed (LF) character…
JDK 17 has been out for a few months and it’s not just packed with new language features. The performance boost compared to older JDK versions is also really significant. It becomes especially clear when compared to the previous LTS releases, JDK 8 and JDK 11. Much of the improved performance comes from new features…
Introducing QOI — the Quite OK Image Format . It losslessly compresses RGB and RGBA images to a similar size of PNG, while offering a 20x-50x speedup in compression and 3x-4x speedup in decompression. All single-threaded, no SIMD. It's also stupidly simple .
Ever wondered what browsers do to get JavaScript to execute quickly? Let’s take a look.
I talk about tree sitter, CEDET, and Combobulate -- my "paredit-style" package that's designed to work with most programming languages.
What the creators of Processing — now 20 years old — did right
Collaboration on rich text is hard to model with plain-text approaches. We review the challenges and how to construct a CRDT for rich text.

In this essay, Carson Gross explores HATEOAS (Hypermedia as the Engine of Application State), explaining how it enables REST APIs through hypermedia responses and contrasting it with modern JSON-based APIs. Using clear HTML examples, Carson demonstrates how HATEOAS allows clients to discover available actions…

I’ll be walking you step by step on how I built a bare-metal, 3-node Kubernetes cluster running on Raspberry Pi. I'll also share some tips and tricks I learned along the way.
Can we move our development environment from our local machines to a remote server, and interact with it through a browser-mediated IDE?

How I got nerd sniped into benchmarking legacy x86 instructions
You might have heard people say that functional programming is more academic, and real engineering is done in imperative style. I’m going to show you that real engineering is functional, and …
Git ls-files is up to 5 times faster than fd or find in this benchmark, but why?
