I had a good rapport with the students; also, the AC was out & it was hot.

I had 6 identical lab (secondary teaching) sessions per week, each 1 hour long. I handled lecture once a week, for two blocks of 400 students. It’s the equivalent of a decade teaching per school year.

I was the only English-speaking TA (&, thus backup lecturer) to "Intro to C 101" at a major mass-population state university. Class sizes were ~800 students. I had an open-doors/open-lab/open-office policy. By the 4t

My brother had a stressful afternoon in court a bit more than a decade ago with the same “yes” obviously spliced into a recording. The judge was pretty humored by the recording and kept asking the plaintiff (the scammer) to play it over &

You linked to ... woo? Like, this is not even science. I asked for a mathematical explanation of how to utilize the more exotic invariants of momentum in nonrelativistic spacetime, voiced in terms of GR. If the GP is going to claim this dri

Ok, I’ll bite: how do we manipulate local nonrelativistic spacetime curvature near a spaceship to take advantage of the magnetorestrictive properties of this material? I’ve just finished my last undergrad-equivalent course GR, so voice this

That’s unfortunate; I think the KP line breaking algorithm is one of my favorites. Obviously, it’s not as fast as greedy, but it is “mostly” linear. Here’s my notes & some C++ code… https://github.com/jaroslov/knuth

I wish, SMT-solvers, in particular, were easier to approach. I have a number of problems that are solved once-per-month, that I wouldn’t mind throwing a couple of weeks of compute at to get absolute tip-top results. Posing SMT-problems thou

Weellll... I guess you could get rid of the OS and switch to a stack-only ABI with a callee saves-everything policy? Then "thread switching" and "multiprocess" both map onto saving/restoring the stack (on ARM you&#x

You must not have the right kind of ‘friends’ on Facebook; the fallacies you listed are straight up on my feed. My favorite one is that wind turbines aren’t recyclable, therefore moar coal!

I asked my great grandmother (who was born in 1891) what she thought the most amazing thing she’d seen. (This was about 1988.) Answer? Cheap large print books.

This is a great concept for a near-future sci-fi short story, though.

You either sort by cone, getting great gate-value reuse density, but lose gobs of parallelism; or, you sort by gate-type & eat-shit on gather-scatter. It’s a devil’s bargain, either way. It’s why the majors sell $$$…$$$ custom emulati

I don’t do anything security related — I’m a lowly bare metal programmer — but I’m still mystified as to how user passwords are securely kept on disk? The only thing I could think of was to encrypt a user’s password with their password…

Having gone down this path while sizing my water system ... it depends: (1) environment; (2) precisely what you mean by "survive"; and, (3) how healthy the water is. There's a lot of variation there. If you look at off-grid

Rain is an intermittent resource. You need to size your capacity to some standard deviation above the mean to get to some confidence level you’re agreeable with. In Central Texas, where I’m at, 10k gallon of for a family of four is sufficie

Discretionary income for a lot of families is — functionally — zero. The result is that any sort of financial issue becomes a devastating (possibly lifelong) burden. Most of these issues are single-occurrence and probably fall in the 200–

You’re describing an idea adjacent to “mastery” schooling; it’s the natural method people tend to use when self-taught; it’s also how some online schools, like Khan Academy, use to teach. Both of my kids earn “allowance” (extra screen time;

We have the americana all over central Texas; the stalks that grow here are more like vertical rope , smell like death & are green/brown all the way through. They’re also segmented & don’t get nearly fat enough as shown.

I don’t know why you’re being downvoted; for sure, one issue that I see skipped over is what we called “competence” — HIV is incompetent , whereas flu is competent : regardless of transmissivity (Re), you can ask how easily a virus infect

A vaccine, a mask, and social distancing reduce the probability of getting sick. In particular, a vaccine does not make you immune, like some sort of cartoon superhero. Instead, a vaccine dramatically improves the response time of your immu

I have family and friends in Israel; also, about a dozen close colleagues. Israel has used a fairly sophisticated version of mask+distancing+vaccines since day one. This has flattened their infection curve, admirably. Or … just to make sure

I’m trying to understand your comment in the most positive way I can. However, you seem to be implying that either mechanical prevention measures (masks; distancing) or biomedical (vaccines) would be ineffective in treating and/or prev
