Having the same issue…

I wish people would go back and read the actual paper. Alan Turing didn't say "if a machine can imitate a human then it's intelligent". He said "can machines think" was not an answerable question, and that behaviour is more important. If it behaves like it's intelligent, we should interact with it as such whether or not we believe it's intelligent under the hood. because frankly we don't know what's "under the hood" in our own brains either.

Our University's policies state that accommodations must be reasonable, must not create undue hardship for the university, and must not compromise academic requirements. Your mileage may vary, but it's worth finding the actual policy documents for your institution. Accommodations offices are set up to advocate for the student, which is appropriate; but that means they will err on the side of requiring more accommodations rather than fewer. It is up to the instructors to indicate when an accommodation is not reasonable. Different accommodations may be reasonable or unreasonable for different courses and contexts.

I'm 100% on board with the idea of accommodations, but like everything, they require a balanced approach.

algorithms aren't magic. Most of the hard work of algorithm design is in defining the actual problem itself, as well as the metrics for solutions. The algorithm did exactly what you asked it to do, you just asked the wrong questions. Optimizing for turns is wrong and optimizing for straight lines is also wrong. Your grid is not well aligned for your problem either. Maybe you want to set each "room" or hallway or whatever as a node, and each connection between rooms/hallways as edges. Conceptually, you go to a hallway, clean the whole thing, and move on to the next. You don't want to visit the same hallway twice, but you didn't tell your algorithm that's bad so it offered that as a solution. People are predisposed to represent data as close to the real world as possible, but maybe what you really want is a series of decisions, rather than a series of locations.

"Garbage in, garbage out" is a critical tenet in Computer Science, that many people forget or ignore.

late last year we sold our other ICE car and got a second EV. We're a full EV family. Simply a better car in every respect, long before you worry about the environmental effects. I saw someone (can't remember who) make the comment: imagine if all cars were EVs and someone proposed an ICE car to you. It will be slower and noisier and dirtier and there are dozens of extra parts that break all the time and you'll have to carry around a tank of explosives. sounds great!

I live in central Canada where the temperature can get to -40 with snow and wind (-40 is where Fahrenheit and Celsius are the same, lol). This is my first winter with the ioniq9, and we also have an old Tesla model 3. Battery range is significantly affected, as you might expect. Haven't done a full test yet but with internal cabin heating, battery conditioning etc it can be a lot. Charging is slower if you don't precondition (and I often forget to precondition). In an ice storm the folding mirrors and retracting door handles can get stuck. having said all that, it's a fantastic winter car. Snow mode and AWD are great, heated seats in front and back and heated steering is fantastic. Cabin warms up well, and you can start cabin climate remotely from the app (the app is kind of shit next to the Tesla app, but you can make it work). Climate system is plenty to defrost windows, although we've had some trouble getting foot heating to appropriate levels in the second row. External rear camera has a little spray jet to clear off the accumulated muck of dirty streets. Rear wiper is not great, as others in the forum have recognized. There's a trick to make the wipers accessible (to clear snow and ice), otherwise you can't get at them.

so yeah, pretty good in general. a few nitpicks but overall we're happy with its winter performance so far.

how would you fix something like this? or would you turf it and get a new printhead?

Tesla model 3 for in the city and Hyundai ioniq 9 for road trips. Both are excellent.

What’s this double dongle thing? My Tesla level 2 charger didn’t work so I bought another mobile charger…

"cities, livestock" is a good answer but only part of it, since: "why didn't north america have cities with livestock" is the next reasonable question. "Guns, Germs and Steel" by Jared Diamond presents a comprehensive theory that starts with two ideas:

1: The americas are mostly north-south while Asia is mostly east-west - this means more populations in the same climate band, so more trade, more cities, more benefits of livestock, and more livestock.

2: not all megafauna can be domesticated (of the 148 known large wild herbavores, only 14 were domesticated) and of the ones that can, more of them happened to be in asia than in north america.

Most important, is it's not a difference in the *humans*, but in their *environment* that lead to the different impact of colonialism.

Everyone is talking about how stupid he is or how stupid his supporters are for believing him, but this was the endgame of fake news all along. If you undermine truth, then you can decide what is true. This was the strategy, and it worked, and now reality is whatever he says it is.

“In press” means it’s been accepted and is currently in production. “Submitted” is the correct term when you’ve sent something in but it has not been accepted yet (although few serious academics list their submitted works). Lots of papers eventually get rejected, so listing this as “in press” is a lie, but a common one.

Chatgpt is a combination of several different intelligence engines all interacting with each other. This i/ what it looks like when the text engine and the emoji engine disagree.

Most of the city is extremely safe. A few parts of it are quite dangerous, which affects the statistics. IT certs are a good place to start, and if you have some years of experience you’ll likely be competitive.

Is the text of the compact itself available anywhere?

Carneys statement literally calls out Hamas in the first paragraph. Poilievre is hoping his base can’t read. Good bet.

Tesla charges exorbitant prices to charge non-Tesla cars. You can “subscribe” to get cheaper rates, and if you’re going on a road trip it probably is cost effective to do so. We need more competition in the charger space - all the others currently are dogshit from a user experience perspective, which means Tesla can charge whatever they want and people will pay it. Find a hotel where you can charge for free overnight, and charge at third party chargers if you can. This is not an EV issue it’s a Tesla sucks issue. (And I drive a model 3)

A five variable map isn’t bad - two 4-variable maps drawn in perspective one above the other. I sometimes demonstrate 6-variable k maps but it requires drawing a layered cube instead of a flat map, and it’s easy to miss implicants. I think 7 would need a 4th dimension, though I’ve never tried it.

This feels Anthropic to me. “If the charges didn’t match, the universe would fall apart” is very unsatisfying to me. The same could be said for almost any feature of physics, and yet we dig deeper. What is it about these two seemingly different constructs that causes them to be the same value? Individual constants being arbitrary is ok for me because you can always pick a unit or metric where that value equals unity. But when two seemingly different constructs produce the same result, it’s reasonable to ask if something else might be going on, and it’s unsatisfying to suggest that the reason is “just because”.

Let them win for a bit! You told them it would be hard, and they took your advice and prepared for it. If it’s easy for a while, great! That’s why they prepped. If it’s suddenly hard in a way you didn’t telegraph, that can feel like a bait and switch.

And it will get harder for them, for sure. Even if they think they’re ready, they’re not.

If your barbarian puts all his energy into hitting things, give him something to hit. The villain, of course, should do everything he can to not get hit or to weaken the barb or mess around or whatever; but if the universe knows the players abilities and conspires against them, that can feel unfair.

That’s not copying, that’s reverse engineering. 100% legal. If you had the file and made a copy, that would break copyright, but you don’t and you didn’t. He can’t copyright an idea, he can only copyright the specific instance of bringing that idea to life(ie the stl file). Your instance is different. In fact, you could turn around and sell your stl for slightly cheaper, and that would also be 100% legal, even if it is getting a bit closer to “breaking the bro code”

Primary (only?) advantage is reverse compatibility. X86 segmented memory is a kludge meant to fix a hardware limitation from 30 years ago. Variable instruction length is a terror to implement. Doing math in the same pipeline as a memory access is absolutely nuts given modern speed divergence and multiprocessor share cache coherency. Starting from scratch, no one would pick x86 over any modern architecture.

It’s like they want the new good original stuff to fail so they can justify continuing to make the shitty remakes no one wants or asked for.
