TIL that POSIX doesn't require support for the %s formatting for seconds-since-the-Epoch in either strftime(3)ยน or date(1)ยฒ. Most implementations do, but its absence caught me by surprise during a little POSIX shell-scripting.

People who know more about Asterisk than I do:

I have a device that will give me sound data, hook status, and tell me when a button is pressed. If I want to plumb this into Asterisk, what's the best approach? I'd rather not deal with an out of tree channel, so it /seems/ like ARI+chan_websocket is the best approach, but I'm not clear on how I'm supposed to know that enough digits have been entered to initiate a call, for instance (just keep originating with a longer set of numbers every time?)

After two weeks with motions I get the hang of some things but need more time for cursor positioning.

Like how deleting to the end of a line after a space to reword something, and pasting would restore the original line, but when you 'i' insert instead of paste, you type "in front of" the space character instead of after.

Keeping track of the actual cursor position (and picking 'a' to append to the line after the space instead of 'i' to insert before) confuses me a bit still.

Great. Took a 7:15 train to get to the office on time so Iโ€™d have some time to re-read my notes and set up my laptop etc before teaching a lecture at 8:45, but because of a โ€œpower failureโ€ there are no trains between The Hague and Delft, so now Iโ€™m sardined into a delayed street, and will, in a best-case scenario, run sweatily into the lecture hall at 8:45 sharp ๐Ÿ˜ฉ

At least there is a streetcar, I guess.
