Don't let dicts spoil your code
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.

Practices of Reliable Software Design
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.

A modest critique of Htmx
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.

A popular but wrong way to convert a string to uppercase or lowercase
Converting character by character isn't good enough any more.

The costs of the i386 to x86-64 upgrade
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 dynamic linking depends on the active code page
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…

Rust is rolling off the Volvo assembly line
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.

Building a single-page app with Htmx
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.

The Rise of Worse Is Better (1991)
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:

How do HTTP servers figure out Content-Length?
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!

Gleam Is Pragmatic
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…

(Re)Using rustc components in gccrs
In order to speed up development, as well as make sure gccrs exposes the exact same behavior as rustc in critical compiler passes, we decided last year to start reusing components and crates from the official Rust compiler where possible. These components range from external crates used for certain nightly options to…

Separating code reasoning and editing
An Architect model describes how to solve the coding problem, and an Editor model translates that into file edits. This Architect/Editor approach produces SOTA benchmark results.

You Too Could Have Made Curl
https://www.youtube.com/watch?v=kCJmAyUr1j4 This is the video recording of my talk with this title, done at February 4, 2024 10:00 in the K1.105 room at FOSDEM 2024. The room can hold some 800 people but there were a few hundred seats still unoccupied. Several people I met up with later have insisted that 10 am on a ……
