If you were to dig straight down from where you’re standing and pass straight through the centre of the Earth and keep on digging — you’d now be tunnelling up I guess — where you come out would be your antipode. Though most of them would first have you springing a leak at the bottom of the ocean, so be careful.

Antipodes

Smaller software releases generally means fewer bugs, and bugs that are easier to fix. The number of bugs created typically increases with the complexity of interactions of code, which in turn increases with the size of release. This means that a number of smaller releases can hopefully get you to a large change in a safer way with less bugs, and less problematic bugs, created along the way than a single release with the whole lot. There’s probably a somewhat more general relationship with amount of unexpected problems created and the size of any change.

Bugs and releases

I’ve never used one, but I’d love to. They seem a little like magic. Basically, you pressurise the air of an underwater box enough to keep the water from coming in. This enables you to have a kind of swimming pool entrance to water even though you’re already actually underwater. So cool.
