In scuba diving and aviation safety is a discussion that takes place before and after every dive or flight. It is discussed every time divers meet up. With climbing safety is important too but the focus is different. “This is how you should belay, this is how you should climb, this is how you should set up the top rope, and more. With climbing I know what the safety rules are but I don’t necessarily know what the numbers mean.

Recently I have been listening to plenty of Late Night Linux podcasts. I like them because they’re half an hour long, the adverts are half way through the show, and in general I don’t feel that they’re filling time to fill one and a half hours of podcast time. Plenty of other podcasts last for an hour and a half or more, which if you listen to one episode a week is okay, but I don’t do that.
