Git version 1.7.8, which is shortly to be released at this writing, contains a handy new program git jump. The idea is that you can say things like git jump diff to have your $EDITOR go directly to the lines within your files that contain unstaged changes.

The design of git jump is particularly helpful for Vim users, but what if you prefer Emacs?

Sometimes the code running a dynamic website will encounter errors. There are a variety of ways to handle runtime errors, of course. Some are better than others, and today I encountered a site that manages to get a surprising number of things wrong.

One of the great things about open-source software is the ability to reuse handy classes written by other people. But sometimes, you find yourself using a class that doesn’t have quite enough features for what you’re trying to do. What’s the best way to deal with that sort of situation?

I was recently surprised to notice an area where orthogonality and consistency suggest the existence of an arithmetic operator which (to my knowledge) no programming language offers.

Last weekend, I was at the All Tomorrow’s Parties festival in Minehead. It’s unusual as music festivals go: it’s held in a holiday camp, which is great for those who, like me, find that the pleasures of actual tent-in-a-field camping are no match for those of beds and indoor plumbing.

One of the great things about Git is that it makes branching and merging so simple as to be a delight, not a chore. One of the consequences of that is that you tend to use far more branches than you would if you were using a lesser revision-control system. Which can make it easy to forget which branch you’re on at any given moment. So wouldn’t it be nice if you had a simple, easy-to-see reminder of where you are, visible at all times?

Once upon a time, handling signals in Perl code had a pretty big gotcha — one that you couldn’t work around. Perl 5.8 changed signal handling in a way that eliminated that gotcha, but replaced it with a different one, harder to trigger, but no less surprising.

JavaScript is a fine language in many ways — a fact that many people have noticed by now. But one of its biggest problems is the design of its standard library. There’s a lot of low-hanging fruit to complain about; this note covers just Math.max.

What do you do when you’ve got a large collection of chillies in the house? Well, if you’re us, you make harissa.

Yesterday was the 2008 Doors Open Day in Edinburgh: each year, for one day only, a variety of buildings open their doors to visitors, free of charge. A large number are places that you’d never normally get the chance to visit.
