I'm being told that it's time to wake up by Laureline kneading on my shins and purring so enthusiastically that she's also cooing.
Of course, Valérian has come to join her.

Oh, man, how has no one quoted the Panashiba PSA from Tales from the Afternow yet?
"This is a Panashiba reminder to make sure you only practice what certified instructors have taught you.

I'm reminded that I had to explain burning CDs to the kids this past week.
"The proper term was 'recording,' but we used 'burning' both because it sounded cooler and because CD recorders used a laser to cut the pits in the substrate of recordable media, more or less by actually burning it."

I'm finding that computers are a good idea on paper, but the execution is quite poor.
Through no fault of my own beyond insisting on running updates, VcXsrv and Emacs are broken on Windows, so I now have access to neither acme nor org-mode.
This is unlivable.

I will forever find it funny that USB mass storage gives you two options for how you'd like your disk: floppy or "scuzzy."

Oh, there's a runoff election happening yet, it seems. That wasn't clear a few weeks ago.
The only thing that tipped me off to it was Rishi Kumar crowing in my inbox about how he intends to use an elected bureaucrat's post to protect prop 13 and how he disapproves of a natural gas ban.

I made the mistake of doing some Hanon-inspired exercises on the bass last night, and writing is very hard today. Oops.
But, hey, the upshot is that I (think I) finally have enough feeling back in my hands to take the bass up again, so there's that.

Huh. Ishiguro's "Klara and the Sun" reads a bit like Aldiss's "Super-Toys Last All Summer Long."
At least, David and Klara have quite a few parallels.

So, fun hack I discovered this quarter for Zoom: start a recording of the space you'll be in when it's empty. Then, after, like, 10 minutes, walk behind the chair you'll be sitting in. Stop recording.
Now, use that as your background.

For Halloween next year, I'll just carry around a sign that reads, "Fast forward and rewind are unavailable during ads."
I think I've atoned enough for my past work to have a bit of a laugh at it.

Es ist schon lange her, bis ich was auf Deutsch gelesen habe. Was für gute Bücher (die originell auf Deutsch veröffentlicht wurden, lieber keine Übersetzungen z.B. aus dem Englischen) habts ihr in letzter Zeit gelesen?
Romane, Sachbücher, ist mir ja egal.

"Nate, why differential geometry?"
After having spent way too much time in numerical analysis, discrete differential geometry looks like fun to play around in. (Given some wacky PDE applications to graphs, why not poke at possible DG applications to same?)
Also, soap bubbles and ketchup.

Well, I now have some faculty interest in a baby do Carmo reading.
The two other problem sets (on top of the take-home exam for the same course) were moved to next week, so I can mostly focus on fun stuff after I get that done.
That kind of had me sweating a bit.

I've also decided that the treatment of local curve theory one typically finds in calculus texts is sadistic.
Why cover arc length and then proceed to develop the Frenet-Serret apparatus along with curvature and torsion immediately as if you hadn't?
