This is a simple experimental Lisp compiler, written in uLisp, that will compile a Lisp function into RISC-V machine code. You can run the compiler on the RISC-V core of a Raspberry Pi Pico 2 (or another RP2350-based board):
I am somehow very late to learning CUDA. I didn’t even know until recently that CUDA is just C++ with a small amount of extra stuff. If I had known that there is so little friction to learnin…
TypedDict was introduced in PEP-589 which landed in Python 3.8. The primary use case was to create type annotations for dictionaries. For example,...
This article explains how a game can be made in Prolog by leveraging the hidden power of logic programming. Inspired by the elegance of data-driven design and declarative programming paradigms, I will be explaining a new way of designing game rules which can at the same time be used as the source code of the gameplay…
I recently released papaya, a fast and feature-complete concurrent hash table for Rust. In this post I want to dive into the design and research that went into creating it, as well as why you might consider using it over existing solutions.
Demoscene is the art of pushing computers to perform tasks they weren’t designed to handle. One recurring theme in demoscene is the shadow-art animation “Bad Apple!!”. We’ve played it on the Commodore 64, Vectrex (a unique game console utilizing only vector graphics), Impulse Tracker, and even exploited Super Mario…
A new search engine in 2024? Yes, but stateless — index on S3, serverless — no cluster state, with all Lucene features — filters, autocomplete, facets. And also with local embedding & RAG inference.
My diatribe about adding support for ParadeDB to Ecto
This is a little summary of my current thoughts on Rust. I wonder whether I’ll look back in five years and see if my views have changed.

Our next major version of Deno combines the simplicity, security, and performance of Deno 1 with full Node and npm backwards compatibility, and much more.
I restricted the use of dicts in my code to make it easier to follow and maintain. Here's my explanation of the benefits and advice on what you can use instead. Bonus point: what to do with all the legacy code when there's no time to eradicate all the dicts.
It should have good performance and be able to hold many entries. Reads are more common than writes. I know how I would do it already, but I’m curious about your approach.
At work, we really like the basic simple idea of Htmx. Based on using Htmx in a non-trivial user interface, across a team, we’ve found that the following cases are actually not simple and are quite complicated.

Converting character by character isn't good enough any more.
If you read my previous article on DOS memory models, you may have dismissed everything I wrote as “legacy cruft from the 1990s that nobody cares about any longer”. It's time to see how any of that carried over through the 16-bit to 64-bit evolution.
Windows paths have been WTF-16 -encoded for decades, but module names in the import tables of Portable Executable are octets. If a name contains values beyond ASCII — technically out of spec — then the dynamic linker must somehow decode those octets into Unicode in order to construct a lookup path. There are multiple…
In my job I get to speak to lots of people about Rust. Some are just starting out, some have barely ever heard of it, and then some people are running Rust silently in production at a very large company in a very serious product.
Go 1.23 added Iterators, so lets build a js like streaming api
People talk about htmx as though it's saving the web from single-page apps. Well, I guess I missed the memo, because I used htmx to build a single-page app.
What Rails 8 ships and requires: built-in authentication, Solid Queue, Kamal 2, and production SQLite, plus support timelines and an upgrade checklist.
I and just about every designer of Common Lisp and CLOS has had extreme exposure to the MIT/Stanford style of design. The essence of this style can be captured by the phrase the right thing . To such a designer it is important to get all of the following characteristics right:
Anyone who has implemented a simple HTTP 1.1 server can tell you that it is a really simple protocol. Basically, it's a text file that has some specific rules t…
This update mostly focuses on further bugfixes over actually implementing new stuff, but we have quite a bunch of both!
I’ve spent the past several years working with functional programming languages in my free time – primarily Haskell and OCaml. I love both languages but also find aspects of each frustrating. Haskell is terse and elegant with type classes providing a powerful mechanism for ad-hoc polymorphism. However, it can also be…
(Here begins a comment written by John Carmack in 2014, about an email he sent to a programmers’ mailing list in 2007.)
Efficient software development benefits from local development, it enables faster iteration, better debugging and ensures consistency between local and production environments.
If you do just foo , the following justfile will write a single byte 0x0A to a file named bar:
