The steam linux beta is now open to everyone. I just installed it on my openSUSE PC. Here’s how. Update Andrew Wafaa pointed out that there’s an rpm package providing a much easier installation option that I could have found myself ¬_¬ It wasn’t entirely straightforward as there is only an Ubuntu package.

Test Stubbing with Builders, Real Objects, and Caches
I thought I’d start posting some of my notes on tips for testing. Starting with some tips and tricks for Mockito. Mocking/Stubbing frameworks like Mockito help to test units of code in isolation with minimal boilerplate. A couple of guidelines I like to aim to follow when writing tests are: Each test should assert/verify just… Read more »
Java Abuse: Inline instanceof

So I thought I’d start blogging some of them so I don’t lose them, and other people might suggest other ways of doing things… Read more »

Snow
This morning we had an unusual amount of snow here, more than we’ve had in my lifetime. Most public transport was suspended and the people attempting to drive were quickly getting stuck and sliding all over the place. Motorists were making the classic motorist error. They’ve got too much power. I’ve got half a horsepower… Read more »
