Lisping at JPL Revisited

Thoughts on what a next Rust compiler would do
In Rust in 2023, @nrc floated an idea of a Rust compiler rewrite. As my hobby is writing Rust compiler frontends (1, 2), I have some (but not very many) thoughts here! The post consists of two parts, covering organizational and technical aspects.

JEP draft: No longer require super() and this() to appear first in a constructor
In constructors in the Java programming language, allow statements that do not reference the instance being created to appear before an explicit constructor invocation. This is a preview language feature .

Rust concepts I wish I learned earlier
This past month, I have been enthralled by the Rust programming language given its unique edge for writing memory-safe, modern programs. Over the years, several languages have emerged as the most preferred by engineers to write resilient, backend software. The tides have shifted from Java/C++ into Go and Rust, which…

Common Lisp and Music Composition
Once upon a time, there were many music composition software packages, mostly written in Common LISP. To name a few I know, Common Music, Symbolic Composer (not related to the Symbolics Lisp Machine). Common Music is still available in source code but I doubt if anyone is still able to setup that. Symbolic Composer…

Why we need to know LR and recursive descent parsing techniques
A couple of people have asked me for my thoughts on part of an article from Tiark Rompf called (roughly) “ Just Write the Parser ” which advocates the use of recursive descent parsing over more “formal” approaches to parsing, at least in the context of teaching compilers. I’m fairly sure I read this article a couple…

How Memory safety approaches speed up and slow down development velocity
Every March, developers worldwide each try to make a roguelike game in less than 168 hours as part of the 7DRL Challenge . Roguelike games are hard , involving procedural level generation, pathfinding, line-of-sight algorithms, and more dijkstra maps than you can imagine.

Common Lisp: 2022 in review
And 2022 is over. The Common Lisp language and environment are solid and stable, yet evolve. Implementations, go-to libraries, best practices, communities evolve. We don’t need a “State of the Ecosystem” every two weeks but still, what happened and what did you miss in 2022?This is my pick of the…

A look at Unison: a revolutionary programming language
Unison is a pure functional programming language that comes with a few revolutionary ideas. Seriously, it makes everything we’re used to, like long builds, dependency version conflicts, tests that run every single build even when nothing checked by them has changed, manual encoding and serialization of data, and lots…

Rust for Professionals
This is a short introduction to Rust, intended for developers that already know another language. In the examples, Rust is compared with TypeScript, JavaScript or Java, sometimes with C++ or Kotlin.
