Do you remember the first time someone told you about fork()/exec() for Linux? Do you remember beeing completely confused? I do, and it’s an ongoing pain in the ass for me – every time I want to call something simple without blocking and without worrying about pipes or the structure of exec()/execl()/execlp() parameters, or the …

Trying to find it again.. PowerStream’s Watt Reader Loan Program, could …

The server would have been up for about 6 years if I didn’t decide once to upgrade the hardware, once to upgrade Slackware, and once to …

One of the recent things I was told about is the current list of most popular ideas Ubuntu Brainstorm: APNG Support. I’ll put a screenshot here for posterity: That’s pretty cool. The thing that makes me feel best is the overwhelming positive votes. Looking at the rest …
Continue reading The people want APNG!I’ve been having a really hard time on my new job. I had to help out on a project where I knew nothing about the technology or the code or even the basic concepts. It was so bad at times I thought I would go crazy or else my head would explode. Then I got …

Continue reading Oh Google, WTF?I’ve been reading about literate programming, and was reminded that most programmers don’t write comments in their code. Whether to write them or not is a question that’s asked all the time, in all circles – starting in school and all the way to teams of masters of the known universe like Linus (who I’m …
