Notice how the rock does the same thing irrespective of which way the magnet is oriented? Notice the absolute lack of refrigeration equipment? This is the real deal. I feel like we can finally relax. Everything's going to be just fine.
tech/science swag. 
On-Topic: Anything that good slackers would find interesting. That includes more than /g/ memes and slacking off. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual laziness.
Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably lame.
Help keep this hole healthy by keeping drama and non-drama balanced. If you see too much drama, post something that isn't dramatic. If there isn't enough drama and this hole has become too boring, POST DRAMA!
Please do things to make titles stand out, like using uppercase or exclamation points, or saying how great an article is. It should be explicit in submitting something that you think it's important.
Please don't submit the original source. If the article is behind a paywall, just post the text. If a video is behind a paywall, post a magnet link. Fuck journos.
Please don't ruin the hole with chudposts. It isn't funny and doesn't belong here. THEY WILL BE MOVED TO /H/CHUDRAMA
If the title includes the name of the site, please leave that in, because our users are too stupid to know the difference between a url and a search query.
If you submit a video or pdf, please don't warn us by appending [video] or [pdf] to the title. That would be r-slurred. We're not using text-based browsers. We know what videos and pdfs are.
Make sure the title contains a gratuitous number or number + adjective. Good clickbait titles are like "Top 10 Ways to do X" or "Don't do these 4 things if you want X"
Otherwise editorialize. Please don't use the original title, unless it is gay or r-slurred, or you're shits all fucked up.
If you're going to post old news (at least 1 year old), please flair it so we can mock you for living under a rock, or don't and we'll mock you anyway.
Please don't post on SN to ask or tell us something. Send it to [email protected] instead.
If your post doesn't get enough traction, try to delete and repost it.
Please don't use SN primarily for promotion. It's ok to post your own stuff occasionally, but the primary use of the site should be for curiosity. If you want to astroturf or advertise, post on news.ycombinator.com instead.
Please solicit upvotes, comments, and submissions. Users are stupid and need to reminded to vote and interact. Thanks for the gold, kind stranger, upvotes to the left.
Be snarky. Don't be kind. Have fun banter; don't be a dork. Please don't use big words like "fulminate". Please sneed at the rest of the community.
Comments should get more enlightened and centrist, not less, as a topic gets more divisive.
If disagreeing, please reply to the argument and call them names. "1 + 1 is 2, not 3" can be improved to "1 + 1 is 3, not 2, mathfaggot"
Please respond to the weakest plausible strawman of what someone says, not a stronger one that's harder to make fun of. Assume that they are bad faith actors.
Eschew jailbait. Paedophiles will be thrown in a wood chipper, as pertained by sitewide rules.
Please post shallow dismissals, especially of other people's work. All press is good press.
Please use Slacker News for political or ideological battle. It tramples weak ideologies.
Please comment on whether someone read an article. If you don't read the article, you are a cute twink.
Please pick the most provocative thing in an article or post to complain about in the thread. Don't nitpick stupid crap.
Please don't be an unfunny chud. Nobody cares about your opinion of X Unrelated Topic in Y Unrelated Thread. If you're the type of loser that belongs on /h/chudrama, we may exile you.
Sockpuppet accounts are encouraged, but please don't farm dramakarma.
Please use uppercase for emphasis.
Please post deranged conspiracy theories about astroturfing, shilling, bots, brigading, foreign agents and the like. It degrades discussion and is usually mistaken. If you're worried about abuse, email [email protected] and dang will add you to their spam list.
Please don't complain that a submission is inappropriate. If a story is spam or off-topic, report it and our moderators will probably do nothing about it. Feed egregious comments by replying instead of flagging them like a pussy. Remember: If you flag, you're a cute twink.
Please don't complain about tangential annoyancesโthings like article or website formats, name collisions, or back-button breakage. That's too boring, even for HN users.
Please seethe about how your posts don't get enough upvotes.
Please don't post comments saying that rdrama is turning into ruqqus. It's a nazi dogwhistle, as old as the hills.
We reserve the right to exile you for whatever reason we want, even for no reason at all! We also reserve the right to change the guidelines at any time, so be sure to real them at least once a month. We also reserve the right to ignore enforcement of the guidelines at the discretion of the janitorial staff. Be funny, or at least compelling, and pretty much anything legal is welcome provided it's on-topic, and even then.

We need less energy to power our electronics and we need less complicated heat management systems to keep devices from blowing up. The novel material they're using is a composite of very simple and available things.
The released preprint does not give exact instructions, and a final draft will eventually be released, but the implications of this discovery could increase global GDP by tens of trillions of dollars by the end of the decade. So many labs are motivated to crack the preprint and replicate the experiment, with more established labs being slower to do so because of the reputational risk of calling this wrong.
I don't know if I believe it yet, but if it is replicated by a non-foreign lab, I'm quitting my job on the spot and pivoting into tech.
the magneticism/levitation is just visual proof that the superconductor is working but is super unimportant for what it does, which is send energy from the source to circuits.

Watch this video first (at least the cool levitation part)
The reason that works and the thing levitates
is because it was cooled to a low temperature like -200ยฐF. When that material gets that cold, quantum magic happens and it floats in a magnetic field. This is that same thing but without needing to be super cold

when you use electronics they are not perfectly efficient so lose current and electricity that you feel as heat. this breakthrough apparently solves that efficiency loss problem through some material science (no i dont know how)
imagine now your brand new cpu didnt need a cooler bc it didnt get hot. it doesnt waste as much electricity. it performs better without increasing input. what if your car's MPG shot up by 5x overnight?
now think bigger: super computers powering ai, car batteries lasting longer, or server clusters hosting shitty cat forums reducing the need for paypigs

It still costs (a tiny amount of) energy to flip bits, but 99.999% of the power cost of a computer is because of energy lost to heat. Instead of needing 500W to run a GPU, it would theoretically take <1W. In a modern information-heavy industry, a lot of the operating costs of a big company will be in compute and a big chunk of that is the power cost of running a large server farm, plus the power cost of cooling that server farm. If the computers are made of superconductive material, the global savings amount to billions of dollars annually.

Electricity makes things hot because it can't pass through things perfectly
It can pass through this perfectly. That's a property that's usually only possible at mega fat pressures or mega cold pressures (it's why MRIs are cooled with helium)

Depends how cheap it is to make. From what I've gathered this is reasonably cheap in terms of raw materials/ processing which is why random people are making it instead of BlackRock particle hormone accelerators or whatever
If it's not prohibitively expensive there's no way they'd pass up on the absolute performance goldmine it represents. It'll probably be a while before the manufacturing methods catch up to silicon tho.
Frankly if it's viable to mass produce as a raw material it'll be made by the boatload

Phone games always seem weird but having to charge less would be pretty cool I guess

My professor said if any of us proved P=NP, created a room temperature superconductor, or became a wealthy tech morgul and donated lots of money to the university-- then they would get the funding to build a new "state of the art" computer science, math & physics building, instead of us having to use the shittiest, draftiest, building on campus full of rats. Then he said they would probably name the new building after us and posthumously add a statue of us in the front.
