Depending on where I'm tracking, I generally use either FastTracker 2.08 or SoundTracker - not the original, but a new program that is basically an XM editor for Linux.

Most people in the US do.

Except that the standard way of storing times as a POSIX timestamp (number of seconds since the epoch) specifically doesn't include leap seconds.

Being able to inspect the source isn't the be-all and end-all. In some cases there may be more than you bargained for.

It depends very much on specific circumstances, of course, and with the fast progress of software nowadays you'd really need to be in control of both the compiler source and the target's source to pull this off. But the possibility is there.

The best first programming paradigm is one that doesn't involve the word "paradigm".

(You should watch out, you'll become a manager that way.)
