Problems with CSVs (2016)
Much of my professional work for the last 10+ years has revolved around handling, importing and exporting CSV files. CSV files are frustratingly misunderstood, abused, and most of all underspecified. While RFC4180 exists, it is far from definitive and goes largely ignored.

A hiring test I'd like to run
(For the avoidance of doubt, I have nothing to do with hiring at my employer. This test is probably deeply problematic in ways you'll angrily Tweet me about.) I'd like to tell you a story!

A vision of a multi-threaded Emacs
The Threading library Starting in Emacs 26 some very ambitious changes were added. Basic thread support was enabled, laying the groundwork for a future concurrent emacs. The docs layout this possibility: Emacs Lisp provides a limited form of concurrency, called threads. All the threads in a given instance of Emacs…

Every language fixes something - a DiGraph - just for fun
Oh, and - added later - the original from PG is undated, but the "enhanced" version below it was on the C2 wiki in 2003/2004 and possibly earlier, so don't for one minute think it's supposed to be up-to-date, or refer to modern version of these languages.

Notes on Type Layouts and ABIs in Rust
Over the years I’ve found myself with a weird amount of knowledge about how types and ABIs in Rust work, and I wanted to write it all down in one place so that… it’s written down in one place. Much of this information can or should be found in the Rust Language Reference and the Rustonomicon .
