I was pretty pleased with this program I used as a motivation for understanding virtual memory.

11 printf("[parent] %p\n", &vals);
12 wait(NULL);
13 printf("[parent] %p %d\n", &vals, vals[0]); // will this print 9999?

15 else {
16 printf("[child] %p\n", &vals); // will this print the same as line 11?

When you open the game in an emulator so it's in its own window but the emulator miscalculates the size because it thinks it's fullscreen, that's Doom scrolling.
If you are obsessively reading about human-made channels for water in the form of an open declined gravity chute was walls are raised above the surrounding terrain and which use flowing water to transport materials (not to be confused with a trench, ditch, or aqueduct), it’s flumescrolling
If you’re obsessively reading about empiricism, skepticism, and the slavery of reason to the passions, it’s Humescrolling.

Are there any benchmarks (etc) which show the costs of the SysV x64 ABI relative to a somewhat-or-perfectly-optimal ABI for that program? [Not for single microbenchmarks, because I can definitely create horrible overheads there, but on larger programs / benchmarks.]

[Werner Herzog voice]: The computer… it is a cruel, unfeeling god. Left too long in its ceaseless hum, it festers with demons. The human, fragile and insignificant, clings to the ritual of restarting… as if this act could stave off the abyss of digital chaos. But the darkness always returns.
I'm not really superstitious about anything, except the computer, which must be restarted if it has been on too long, to cleanse it of bad or negative energies

I've now given my talk “High Standards, Multiple Tries – How I've Been Grading” a few times. I wrote it up as a blog post:

3 principles:
1. Standards-based grading with high-fidelity assessments
2. Retries for everything
3. Coarse rubrics (0-4 not 0-100)

TIL about document.currentScript

`document.currentScript` is more useful than I thought.
After discovering and being unsure of its value, I just realized how useful `document.currentScript` can be in exposing configuration properties to `<script>` elements (and other things too).

Why is the gap between Rho and Sigma, and not between Pi and Rho? I could see wanting to keep some latin <-> greek-ish correspondence, but Rho is more like R than Q, right?

I am installing tip preventing straps on a dresser that we moved. I have:
- snapped off a drill bit
- stripped a screw
- gotten a screw stuck that I can’t get in or out
- gone through a full charge of the electric drill
These hands were just made for VScode and email, I’m afraid.
