Elixir was built on Erlang. Erlang was built to provide "consistently low latency" and a few other audacious goals. Note, this is not a hard realtime constraint. It is soft, squishy and yet, important and real. It makes Erlang unusually suitable to systems where latency matters and where a near-realtime experience is…
In C++20, string and vector are marked constexpr, which means they’re somewhat usable in compile-time programming. For example, we can write:
This is the first part of a series of posts on big changes for SymPy with particular focus on speed. What I am going to describe in these posts are:
Elixir is a language with syntactical roots in Ruby. It also carries the Erlang legacy. Legacy used here as in "a great legacy" and not as in "system you don't like anymore". Ruby is an object-oriented language. Elixir is functional language. The Erlang part has an impact as Elixir was designed to provide strong…
What's new in Emacs 29.1? I go through every change and annotate the ones I feel are interesting or worth knowing more about.
A comparative study of processor architectures.
YJIT’s ability to improve performance by adapting to run-time behavior can increase the speed of our code in a way that dropping down to C can’t. As such, I think we should reconsider the common wisdom that “rewriting our Ruby in C” is the ideal path to performance optimization and take a serious look at “rewriting…
Create animations from first principles and morph between different figures with Python. In 5 minutes. Kind of.
Replacing an internal Node.js module with a native Rust module made a x25 perf boost. Let’s understand why.
Discovery and walkthrough of CVE-2023-38633 in librsvg, when two URL parser implementations (Rust and Glib) disagree on file scheme parsing leading to path traversal.
Statistics and anecdotes about PHP at scale.

This year, the React team unveiled something they've been quietly researching for years: an official way to run React components exclusively on the server. This is a significant paradigm shift, and it's caused a whole lot of confusion in the React community. In this tutorial, we'll explore this new world, and build an…
We’ve noticed an unusual training pattern in fine-tuning LLMs. At first we thought it’s a bug, but now we think it shows LLMs can learn effectively from a single example.
You bump into DORA in the wild a lot.
Deno KV, the easiest way to add a strongly consistent database to your app, is now in open beta.
Update: This post sparked a lot of excellent discussion and debate on workarounds, and there are now multiple working solutions to allow certificate injection...
If you ever get a chance to look through the classic Amiga OS source-code still floating around some murky corners of the internet, it is a thing of beauty and astonishing capabilities. It’s an inspirational piece of computing history with unmatched capabilities for the time. Remember, this was all on a computer…

“With more careful calculations, one can win; with less, one cannot” — Sun Tzu, The Art of War .
Today we're introducing Refact LLM: 1.6B code model with infill real-time code completion (including fill-in-the-middle(FIM) capability) and chat.
Discover the hidden power of Svelte – the JavaScript framework that feels like déjà vu. Uncover how Svelte simplifies web development, reimagining JS.
In my view, wget is not a curl competitor. It is a companion tool that has a feature overlap with curl. Use the tool that does the job. Getting the job done is the key. If that means using wget instead of curl, then that is good and I don't mind. Why would I? To … Continue reading The curl-wget Venn diagram →
The Dawn of Microsoft's Golden Age
A deep dive into the theoretical framework and the technical implementation of a text CRDT.
Thoughts on building, shipping and iterating quickly
Over the past two years, I have spent a lot of time working on my Game Boy emulator, GameRoy. It has reached a good point, where it has a GUI interface (including a debugger and disassembler) and passes numerous tests (comparable to some of the most accurate emulators). I even made a port to Android!
This is the story of a clever trick that's been around for at least 35 years, in which array values can be left uninitialized and then read during normal operations, yet the code behaves correctly no matter what garbage is sitting in the array. Like the best programming tricks, this one is the right tool for the job…
