3·5 days agoLink(s) in post contain punctuation and break, at least on my client. Here’s the codeberg link (working);
Sorta, but the sunrise/set are due predominantly to the rotation of the earth about its axis, not the revolution about the sun.
Get that dude some Lycra and a decked out Pinarello!
3·16 days agoF-Zero X for N64 is, for me, the pinnacle of racing games (works great on emulation).
It’s fast, smooth, and pretty straightforward. It even had a random map mode — they were sometimes a bit funky, but it was fun when you wanted something new.
I mean, isn’t that what ringing is for—asking if they want to talk? It’s ok to decline a call.

Best ad ever IMHO (sorry for funky link, YouTube if you prefer).
No dialog, no rampant consumerism (hot sauce is a necessary food), no sex/sexism, no emotional manipulation.

That almost makes sense, but pi radians = 180°
Right, a triangle “has 180deg,” like I said.
in which case π÷n is infinitesimally small. In other words, substituting infinity for n would be incalculable
That’s not how limits work. Substitution is not the same as taking the limit.
infinite and infinitesimal numbers are impossible to express rationally.
That’s not true at all. https://en.wikipedia.org/wiki/1/2_%2B_1/4_%2B_1/8_%2B_1/16_%2B_⋯
It’s not about colloquialism or language
Having one word (or phrase) with two meanings is a property of language.
That’s exactly my point, there are two different colloquial ways of talking about angles. I am not claiming there is a mathematical inconsistency.
Colloquially, a “triangle has 180 degrees” and a “circle has 360 degrees.” Maybe that’s different in different education systems, but certainly in the US that’s how things are taught at the introductory level.
The sum of internal angles for a regular polygon with
nsides is(n-2)×pi. In the limit of n going to infinity, a regular polygon is a circle. From above it’s clear that the sum of the internal angles also goes to infinity (wheres for n=3 it’s pi radians, as expected for a triangle).There is no mystery here, I am just complaining about sloppy colloquial language that, in my opinion, doesn’t foster good geometric intuition, especially as one is learning geometry.
I don’t think we’re talking about the same thing.
If you take a circle to be the limit of a polygon as the number of sides goes to infinity, then you have infinite interior angles, with each angle approaching 180deg, as the edges become infinitely short and approach being parallel. The sum of the angles is infinite in this case.
If you reduce this to three sides instead of infinite, then you get a triangle with a sum of interior angles of 180deg which we know and love.
On the other hand, any closed shape (Euclidean, blah blah), from the inside, is 360deg basically by definition.
It’s just a different meaning of angle.
See, for example, the internal angle sum, which is unbounded: https://en.wikipedia.org/wiki/Regular_polygon
Triangle, “has 180 degrees,” subtends 360 degrees.
Circle, “has 360 degrees,” the sum of the interior angles is infinite.
(I’m not actually confused, it’s just that “a circle has 360 degrees” and “a triangle has 180 degrees” is a little annoying in that they use different definitions.)
8·22 days agoGiven that they specified “caffeinated tea” as also conferring benefit, I would guess it’s the caffeine that’s the active substance here.
Or, malicious compliance by someone with a moral compass. Best is to somehow leak documents wholesale. But if that’s not possible, I think the next best way to all but guarantee that the information gets out is to do a lousy job censoring, and let “The Internet” do the rest. It also makes the administration look even more stupid, especially in the eyes of technically minded folks.
But yeah, not the best and brightest, that’s certainly a possibility.
If Gentoo can be both Chad and Schizo, Slack should definitely be in the Chad category too.
I mean, it’s Torvalds’ distro of choice iirc, which should count for something.
High frequency is generally bad for transmission line losses, so getting power from A to B is better at lower frequency — DC is a great option here.
If we switched to DC, many things would still flicker though as they would presumably use switching power supplies, but those could be relatively high frequency like you said.
Interestingly, airplanes use 400Hz, as transmission over distance doesn’t matter, and transformers can be made much smaller/lighter.
4·30 days agoBut I thought they smelled bad on the outside?
I would probably add “transmit power” in there somewhere, but I guess if you’re assuming regulatory limits then it’s not a big variable.
After reading a few of these I feel like I was either a very boring grad student, or my professors were all very chill. (Or maybe just subject to male privilege.)
A few run-ins with IT, but I don’t think I ever got nasty letters from professors…
