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…

1·3 days agoI’ve been pleased with it. Family is very relaxed about projects like this, but yeah it’s low power draw. I don’t think I have anything special set up but the right thing to do for power would be to spin down drive when not in use, as power is dominated by the spinning rust.
Uptime is great. Only hiccups are that it can choke when compiling the ZFS kernel modules, triggered on kernel updates. It’s an rpi 3/1GB RAM (I keep failing at forcing dkms to use only 1 thread, which would probably fix these hiccups 🤷).
That said, it is managed by me, so sometimes errors go unnoticed. I had recent issues where I missed a week of rsync because I switched from pihole to technitium on my home server and forgot to point the remote rpi there. This would all have been fixed with proper cron email setup…I’m clearly not a professional :)
Not the same, but for my Immich backup I have a raspberry pi and an HDD with family (remote).
Backup is rsync, and a simple script to make ZFS snapshots (retaining X daily, Y weekly). Connected via “raw” WireGuard.
Setup works well, although it’s never been needed.
I wonder, legally, if there is a difference between the companies that simply raised prices, and the ones who kept the price the same but added another line item to the invoice that covered the tariff.
IANAL, but for the former, it seems like the company may be entitled to keep the money (of course it’s morally wrong). For the latter though, it seems like maybe (???) there’s some stronger legal pressure on the companies.
Or not. But at least CAH is doing the right thing, as others have pointed out!
3·5 days agoLink(s) in post contain punctuation and break, at least on my client. Here’s the codeberg link (working);
Indeed. The quoted passage made it sound like this was unique naval terminology, as opposed to standard nautical terminology. It’s not wrong, I just thought it was worded peculiarly.
(It’s not just the Navy — they’re called “heads” on recreational vessels, too.)
Sorta, but the sunrise/set are due predominantly to the rotation of the earth about its axis, not the revolution about the sun.
2·19 days agoThey made the decision that would save the most lives, which is their job.
But they lied to the public, which undermines trust; IMHO this was a myopic decision.
As for the people doing what’s best for society, that’s antithetical to American individualism
Can’t speak for everyone, but Flex Alerts in California do indeed work (it’s when we’re asked to reduce energy consumption).
your faith was proven wrong with both masks and toilet paper being bought for resale at predatory prices, or just to maintain personal supplies at the expense of everyone else.
That’s a fallacy/faulty generalization — I’m not saying everyone behaves well, but from my experience, the vast majority do. The pandemic for me was a time where I really felt like we looked out for our fellow people, at least locally.
In 2020 they recommended against face masks for non-healthcare workers. My understanding is that they did this to conserve masks for healthcare workers, as did the WHO. IMHO that was a really shitty thing for them to have done. Presenting all the facts and pleading with the public would, I think, have resulted in higher trust in them as an institution, ultimately saving lives, but that’s just my opinion I guess.
But yeah, completely agree that even then it was more or less well meaning, as opposed to now.

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.)
2·23 days agoWell f2k me, T1L, t4s!
Where energy efficiency isn’t a concern (maybe a blender or a toaster) this sounds nice, but otherwise…well…lots of wasted energy.
(Of course, it all has to be balanced against the cost of manufacturing/disposing.)
I feel like logging in as root on a headless system and hoping you type the command(s) to restore functionality is a rite of passage.
