It has been updated to address some of the concerns raised by commenters. One of the little things that annoy me when reading code is the unnecessary use of memset() to…

Skills Poor Programmers Lack
A friend and I had a discussion about the basic skills that are often lacking in experienced programmers. How can a programmer work for ten or twenty years and never learn to write good code? Too often they need close supervision to ensure they go down the right path, and can never be trusted to take technical…

Xfce 4.14 released
Why is the release manager late to the party with his blog post? The explanation is simple: We prioritized sticking to the schedule and getting our releases out to everyone as planned, as our codebase was ready. What was not (entirely) ready was some parts of the website, which were brought up-to-date over the course…

Clojure’s Approach to Identity and State (2008)
Many people come to Clojure from an imperative language and find themselves out of their element when faced with Clojure’s approach to doing things, while others are coming from a more functional background and assume that once they leave Clojure’s functional subset, they will be faced with the same story re: state as…

Lezer
I keep coming across people who consider parser technology a forbidding, scary field of programming.

Mostly, this tends to…

The hard part in becoming a command line wizard
I've long been impressed by shell one-liners. They seem like magical incantations. Pipe a few terse commands together, et voilà! Out pops the solution to a problem that would seem to require pages of code. Are these one-liners real or mythology? To some extent, they're both. Below I'll give a famous real example. Then…
