It was a *very* long day today, not helped by the SD card in Julie's phone having apparently decided to stop talking to the rest of the phone. Hysteria ensued. The phone is old and is finally being replaced, but we'll have to see if I can recover any of the data on the SD card.

Work was similarly entertaining, as there is something wrong in the branch where I've been working. We can tell, because the calculations are taking much too long. I have managed to shave off 5%, 6.5%, and 13.5% with a series of successive modifications, but that's not enough. There is something in the changes that is still slowing things down, but I have yet to figure out what.

(I've also found something unrelated that I can fix to shave off some more time, but I'd like to find all of the guilty parties for the slowdown before introducing new optimizations.)

This will be a project for next week.

I am so done.
