ClojureScript 1.7: ClojureScript can compile itself
I’ve been enamoured with languages in the Lisp family ever since I first encountered The Structure and Interpretation of Computer Programs now more than a decade ago. At the time I was disappointed that such beautiful systems found so little use in day to day programming. Lisp seemed both deeply pragmatic (Objects!)…

Biggest image in the smallest space
What’s the biggest pixel size of a PNG image in the smallest number of bytes? I wanted to try to create an image that could be downloaded but whose pixel buffer would be too big to store in the RAM of a PC. Here is a PNG image of 6,132,534 bytes (5.8 MB) and 225,000 × 225,000 pixels (50.625 gigapixels), which, if…

Abandon your DVCS and return to sanity
I’ve pretty much always been a DVCS apologist. I know quite a few people who’ve been using DVCSes since Mercurial and Git, and a few who go back to BitKeeper , but I can totally out-hipster you.

CSS Modules
If you wanted to identify an inflection point in the recent development of CSS thinking, you’d probably pick Christopher Chedeau’s “CSS in JS” talk from NationJS in November, 2014. It was a watershed moment that set a bunch of different minds spiralling off in their own directions like particles after a high-energy…
