Some Reasons to Measure
A question I get asked with some frequency is: why bother measuring X, why not build something instead? More bluntly, in a recent conversation with a newsletter author, his comment on some future measurement projects I wanted to do (in the same vein as other projects like keyboard vs. mouse , keyboard , terminal and…

The Rust compiler has gotten faster again
I worked on Rust part-time for several years at Mozilla. During that period I regularly summarized how the compiler’s performance had improved. For example: 2017-11-12 to 2019-07-24.

Cross-Database Queries in SQLite
I released Datasette 0.55 and sqlite-utils 3.6 this week with a common theme across both releases: supporting cross-database joins. Cross-database queries in Datasette SQLite databases are single files on disk. …

New Elixir 1.12 – The developer’s point of view
The Elixir 1.12 version introduced some significant changes. The main one is the ability to create scripts and import dependencies via Mix.install. The interactive console can be more helpful in the software development, prototyping and debugging processes.

Java's records, Lombok's data, and Kotlin's data classes
While all three remove boilerplate, the similarities don't go much further. Records have stronger semantics with important downstream benefits, which makes them better*. (* not always; depends on circumstances; excuse the clickbait)

Chiptunes on an ATtiny4 and the 3 Cent Micro
Ever since hearing about Rob Miles' Bitshift Variations in C Minor , a 4-voice polyphonic 16 minute piece of algorithmically generated music, I wanted to implement it in hardware. Getting it onto just any microcontroller seemed too easy , so I wanted it to run on the smallest µC I could find — the ATtiny4. A while…

Generics facilitators in Go
Go 1.18 is going to be released with generics support . Adding generics to Go was a multi-year effort and was a difficult one. Go type system is not a traditional type system and it was not possible just to bring an existing generics implementation from other language and be done. The current proposal was accepted…

s/bash/zsh/g
There is simply no way you can do calculations with fractions in bash without relying on bc , dc , or some hacks. Compared to simply being able to use a + b it’s ugly, slow, and difficult.

Seemingly impossible functional programs (2007)
Andrej has invited me to write about certain surprising functional programs. The first program, due to Ulrich Berger (1990), performs exhaustive search over the “ Cantor space ” of infinite sequences of binary digits. I have included references at the end. A weak form of exhaustive search amounts to checking whether…
