Libcurl gets a URL API
libcurl has done internet transfers specified as URLs for a long time, but the URLs you'd tell libcurl to use would always just get parsed and used internally. Applications that pass in URLs to libcurl would of course still very often need to parse URLs, create URLs or otherwise handle them, but libcurl has not ……

Advent of Code Python Solutions, Explained
I first participated in Advent of Code (AoC) in 2017. My co-workers at Formlabs introduced it to me. This year (2018), quite a lot of Formlabs folks are taking part and we have a nice private leaderboard going. I'm having a lot of fun with it. I've been staying up until midnight to work on the problems as soon as…

Why not program right?
(Originally published on CACM blog.) Most of the world programs in a very strange way. Strange to me. I usually hear the reverse question: people ask us, the Eiffel community, to explain why we program our way. I hardly understand the question, because the only mystery is how anyone can even program in any other …

The Art of Picking Intel Registers (2003)
I wrote this article for an online magazine called Scene Zine . Scene Zine caters to the Demo Scene, which is an digital art community dedicated to pushing the limits of computers through a mix of music, art, and computer programming. A particular category of demoscene productions, 4K intros, focus on the final…

Gradual Programming
Programming is a fundamentally incremental (or gradual) process, and our programming languages should reflect that. I show several ways in which program models transition over time and discuss how future research can further a human-centric vision for programming languages.

Porting SBCL to the RISC-V
What better thing to do, during the hot, hot July days, thank something semi-mechanical involving very little brain power? With student-facing work briefly calming down (we've just about weathered the storm of appeals and complaints following the publication of exam results), and the all-too-brief Summer holidays…

The -a to -z of Command-Line Options (2003)
Unix tradition encourages the use of command-line switches to control programs, so that options can be specified from scripts. This is especially important for programs that function as pipes or filters. Three conventions for how to distinguish command-line options from ordinary arguments exist; the original Unix…

Modeling Redux with TLA+
Update 01/07/19 Greetings from 2019! The good news is that Chicago isn’t yet a radioactive crater. The bad news is almost everything I said about refinement in this article is wrong. I’m working on writing a more in-depth, rigorous treatment of refinement as its own article. But this one is currently explaining…
