Search "superdirective superconducting antenna". With normal conductors the directivity of an antenna depends on how many wavelengths it spans; the summation of the currents over the effective aperture. With superconducting materials you can exploit the weirdness in current distribution to make very directional antennas that are small relative to the wavelength.

It could be a game changer for making efficient directional small receive antennas. Normally electrically small antennas are just super inefficient but it's made up for either on the transmit side (like with high power AM radio) or with most of the gain coming from some low noise amplifier (like small UHF wireless devices).
Yes, and NASA awarded SpaceX $278m in 2006 dollars from the COTS program when SpaceX had never even flown a rocket.
Can you please stop taking HN threads further into flamewar? You've been doing it repeatedly lately, unfortunately, and we're trying for something different here.

I realize that the GP could be interpreted as a provocation in that direction but it doesn't have to be taken that way or responded to in this way.

Once was a time when very large parts of the web were dark to me because I would not install Flash

Not an exact comparison, but we've been (near) here beforehand
Start thinking about how FUCKED the tech industry will get when your average person can barely afford the basics, let alone the ballooned price of garbage goods that an advertising economy requires to keep up the current system.
Ok and? We know cars can't drive themselves 100% of the time.
Sorry, to be clear my point is that

1. They have no reputations to put on the line

2. They didn't do anything risky

This isn't like we're talking about the AF Chief of Staff or some major leader in a field. So there's nothing to put on the line, they were nobodies before this and once it dies off they will be nobodies again.

Said differently, this whole debacle will make them MORE famous and employable than they were previously. So the overall impact on their life is that they get more fame and attention for effectively no risk. People seeking fame and attention don't generally care what kind.
Massachusetts Institute of Technology: The Kornbluth era begins
> Filmmaking is still mostly a relationship business, and even with AI actors and writers it's hard to see that changing

I'm not sure about that. The power that Hollywood once had to create and promote stars is fading. This is why we see them endlessly trying to milk sequels and franchises, and why very old movie stars like Tom Cruise and Harrison Ford are still hot.

If people still want to watch Tom Cruise in an action movie in 20 years, they will have to rely on AI. Whether it will be Hollywood providing that experience or not remains to be seen.
Not necessarily. The "strained crystal" approach probably extends to other elements; mixing Pb and Cu works well since there's a large difference in their sizes, but rare earths might work just as well as Pb.
Why did those early experimenters report positive reports? Did they inadvertently do something wrong themselves that looked like cold fusion?
If Starship delivers even half of what they're promising, we'll have a bunch of commercial space stations up even without NASA support.

It's an easy thing to attempt to replicate, and it's probably _the_ single biggest goal in a particular field of science in at least decades.

It's impossible that at least some people didn't drop everything to try it.

Elon also said the Falcon 9 would work, said it would be re-usable, said the Falcon 9 heavy would work, said the Model S would be good, said the Model 3 would be great, said the Model Y would be the most popular car in the world, etc. etc.

Obviously he's not hitting 100%, but you can't deny his companies are achieving immensely more than anyone ever thought possible.

If I could take Elon's ratio of "I said it would work vs. it's real and it does", I would, and so would any sane person.
Looks like good long-term project stewardship.

If somebody just improved all future deadlines at the expense of a delay in one, isn't it great? (Yeah, there are a few times when it isn't; but if those are not few enough to be clearly communicated, your management is a bunch of dummies.)
I'm trying to build an AI powered vocabulary book. it can make unlimited number of sentences and generate quizzes.
> this is unusually bipartisan and seeing Gaetz and AOC both laserfocused on investigating government misuse of money on such a historically fringe subject is most interesting.

Indeed, there was very minimal political sniping. A little bit at Biden about the Chinese balloons, but that was it. I was very surprised - especially with those two in the same room.
Another comment from a well informed source on the topic:

Also, on the sentences in the manuscripts trying to explain the effect: I think that is wild guess at best. The measurement results done in the manuscripts probably can be taken at at face value (at least until there is a reproduction). Whether they really indicate superconductivity or something else that looks like it in some of the aspects is then a different question.
Yes, because bone evidence shows the pre-Columbian Indians suffered periods of starvation, as did the pre-Revolution colonists.

Then there's the evidence that the average height of Americans shot up from 1800 to WW2.

I run an ad blocker on all of my devices (mix of uBlock or Brave browser) and I'm pretty surprised how infrequently sites ask me to disable it to access content. Not sure if your experience is different.
Even less so since this is a proposal for a javascript api.
It is so satisfying to repair things!
Clothes, tools, books, toys, machines, you name it; the process of identifying the problem and figuring out a fix is empowering. I get that not everyone wants to, but repairs really are for everyone, and opting to trash things is just kicking problems along to the next generation.
It is frustrating that paying for boot repair can be more costly than a new pair of boots. Feels like we are undervaluing the material extraction and processing, and losing skills along the way.
> Lifetime thing is a rather large statement, especially with software though isn't it? Most of the pre-subscription model compares were never lifetime purchases. Software that needed paid purchase update every 3-5 years to get OS support / features.

For sufficiently valuable software, people will hold back on an older OS to keep using the software.

A lot of high-end film scanners will come with the 68k or PowerPC mac that’s used to run the software, because the alternative would be spending $20-30k for a new one. And industrial systems run on similar models.
Unfortunately, the racists got there first with their "one drop" policies.

As is usually the case, it's the discriminators that set the stage, and the rest of us who have to act out the play.
My first “real” job the director sat down with me and said “Look, everyone fucks up. It’s ok, someone just fucked up and we are all running around now because of it. Just be honest when you do it and everything will be fine.”

He was right, his department was great to work in. No recrimination for honest fuck ups (I took down a national banks ATMs for a few hours once).

It was a great place to work and everyone was better / more productive because of it. People were positive, honest, and adults!

Years later we joined a larger company. They acquired another company who had 3x the people doing half the work…. They were all about blame and recrimination. Their productivity was absolutely related to their culture. They were so follow the process / afraid of getting blamed (and people got blamed for no reason) that they were terrible / found the worst ways to work.
I’m sure this is on Applied Science’s (a YouTube channel) radar. He recently went on a deep dive on making YBCO superconductors so it’s right up his alley.
RoHS has a number of exceptions. Ambient temp/pressure superconductivity will absolutely be excepted too.
It's a silly comment leading into a more serious question. Everyone focuses on the least important part of the comment, and then feels self righteous
Contamination/impurities or something else in it that's not superconducting?
This would only solve one of the more minor problems with fusion. And what would it do for batteries?
It is not worth it because:

* If you're not really serious about using strings, why would you care?

* If you're really serious about actually doing things with Strings, you are gonna need to reimplement International Components for Unicode (or something similar in scope), and you have a free, libre and already working one for the "UTF-16 String Java" already. You don't have a working one for your custom fork with custom String handling.
It isn't as if Sony and Nintendo are contributing all their changes to upstream.

For example any improvements that may reveal NDA stuff from their consoles never gets upstream.
Does Elon know this?
25 years ago, before I could build out the system we designed, it took weeks to provision hardware.

Now I can stand up an entire data center with databases, unlimited storage, etc by creating a yaml file.

Even 25 years ago I was optimizing code by using inline assembly to get the performance I needed.
Small effect sizes make it easy to confuse noise for positive results. Throw into it the very strong desire to see the thing work, and, well, even the best of us are only human.

Starting with something as basic as bringing back the path input textbox in file dialogs. I mean... it's a file dialog! What else but inputting file _paths_ is it good for?
Now do javascript ;)

[I mean,make the strings use utf-8 instead of utf-16, which is a bit different than TFA]
Totally agree. This is science at it's best, with maximum skepticism (and a dash of hope), in front of our eyes!

Even better, it's a HUGE claim that is going to show how epistemology in science works (reproduction!!)

And then there are sites like https://bt.etree.org/ where artists allow for free and open trading of live shows.

Back in the day before high speed internet became common, you used to subscribe to mailing lists and send "B&Ps" (blanks and postage) of either cassettes or CDs to the person with the original copy and they would burn the copy onto your media and then mail it back.

With bittorrent now it is a lot easier to get copies of live music, but it feels like the community that was there faded.

I don't think the actual proposed superconductivity mechanism is the relevant part of this paper. It is much easier to prove that this is superconducting than to prove why. And in a sense it is a bit less relevant. Although developing a working theory for room temperature is also probably worth a Nobel prize, so I am willing to bet some theorists are also running to their blackboards as we speak.
Overture could be seen as hostile to OpenStreetMap, but I do not think they are washing any licenses here. The article explicitly says that the CDLA license applies to data provided by Meta and Microsoft, not data from OSM. I think it's unfortunate that Meta and Microsoft aren't contributing their data to OSM instead of releasing it under a different license, but c'est la vie.
My personal views are somewhere between Bakunin and Benjamin Tucker. Private companies can be equally or even more coercive than a government. In this case, via the OSHA mandate and the executive orders on defense contractors, we saw both acting together.
We really are what we eat.
Ensure you use the dysfunctional version of that, where some individuals are always outvoted.

Personally I don't think PATs are nearly as bad as WEI. PATs just bypass CAPTCHAs while WEI will presumably lock people out of sites completely.
Let me add: 1) Always micromanage down to the lines of code changes. Have your reports depend so heavily on your next-steps that you maintain your influence on them to the point that nobody can make strategic decision when you are on vacation. 2) Encourage narcissistic, rude, and self-serving behaviors in the teams to the point that the other team members would think that there is no way ahead other than copying these behaviors. Praising one particular toxic dev on a weekly basis (and ignoring all the rest) works perfectly well. 3) Say one thing - do another. Verbally encourage work-life balance, taking care of own family members, creative problem solving, maintaining code-debt, good documentation etc but makes sure to praise the one dev who burns the candle at both ends to report that a project is "DONE" as fast as they are humanly possible (without any detail of what is being done). 4) And last but not the least, definitely throw devs under the bus when a project failed without mitigation plans and definitely do not let the dev amend for their mistake because heads need to roll. 5) Extra tip, isolate devs and DO NOT let them talk to each other (easy during pandemic) in case they form better camaraderie because shudder we definitely do not want them working together! They only need to take instructions from the manager gosh!!
Or they were actually asking for time to officially work on it. Thinking their superior must have a good view of the big picture. Waiting confirmation that their idea made sense in the grand scheme of things.
WEI is like requiring people to get their brain scanned before you let them visit your house. "Sorry, I require a valid attestation from Google that you are a real human," you say. Your friend now needs to drive down to the local Google® Privacy Invasion Center™ and have all of their personal secrets exposed so Google can prove they are, in fact, not a robot. Except, oh no, Google found Linux in their brain scan! The horror! How dare they value their own freedom! Anyone who opposes spying from Chrome and/or Google Play Services is obviously a bot. Nothing to hide, nothing to fear, right? Your visitor, who is clearly not a bot, fails to obtain a valid attestation from Google. You deny them entry to your house.

You have lost an acquaintance.

People generally have pretty good spatial sensibilities, and I feel like modern OS designers seem to forget this. You feel this especially on iPadOS.

Physically arranging windows allows for a much more solid multi-tasking experience, and encouraged direct manipulation of content e.g. drag and drop. Transient "palette" or "panel" windows allow for a short term buffer (think a find/replace panel). To me, this is what made macOS so great for creative tasks. It activated my spatial memory.

I'm grumpy about the recent trend towards apps living in one monolithic window. Apple's going down this route with their recent app redesigns from multi-window to single window, likely due to a (selfish) desire to unify with iPadOS. Electron adds a dev tax for multiple windows, such that folks don't really think to do it.

I think this trend is probably due to the convergence of desktop app design with the web, which is inherently single window -- and traces its roots back to window.open() being abused by pop-up ads.

It's unfortunate because a single window user experience is limiting -- and people are forgetting that anything else is even possible. I miss the days when chat apps had separate windows for each chat, and a buddy list you could pin to the side of the screen.

(If you've only ever got comfortable with a windows-style "maximised window" approach, you'll probably disagree with me, however).
Reminder that we live in the same universe where China has basically entirely pwned our government networks, Russia has done a good number, and a 20 year old desk worker had the ability to post insanely high level stuff to a discord server for quite some time before anyone even noticed.
I would posit that "smarter" models like character.ai or the recent llama finetunes are potentially healthier because they are more deductive, and less submissive. They will push back.

And bots like this are a good temporary resource for socially isolated people in bad situations.

This is still a worrying trend though. And while people have been whining about getting "sucked into" fiction for centuries, some of the commercial bots really are dangerous because they are designed to suck you in.
Sure but they didn’t do anything here but apply a microcode patch…

Heck they are taking attention away from the original authors and what shining a spotlight at their hardware partner’s flaw?
Amazing! Hope it is not impolite to ask: I assume even nothing if you just doze away and something wakes you quickly again (I believe many have the mind wandering, crazy thoughts, but no visual dreams there)?

Can you doze at all, or is it always quick deep sleep? (would sound desirable)

Do you have or feel any impact, any disadvantages? Because sometimes a lot beyond the basic sleep is attributed to being able to dream?
So, being old = opinion invalid?

We've fallen into decadence, and with it has come the desire to freeze society as it existed somewhere around 1965, when baby boomers turned 20. I've had conversations with people asking how new Marvel movies could be made if some political or legal change happened. Who cares?

Don't care if no one ever writes a novel again, there's plenty to read. It'll never happen, though, because people will write novels for free, and people will sponsor people who create things that they want or that they want to be seen sponsoring. Don't care if there's never another piece of recorded music, and we're stuck playing music with each other or being in the same room with people playing music for us. Of course, this will never happen, because the vast majority of music is made for free, and the rest nearly for free after the record companies recoup.

The state doesn't need to keep encouraging the production of art through police action. If the state wants to encourage art, give everybody a tax credit that they have to send to an artist.
You provided an timeline of human evolution, but has fundamental physics changed at the core?

Unfortunately, we haven't found any drop-in replacement to Newton's first & second laws for e.g.; Conversely, more & more of physics is condensing towards established standard models proving that our model of universe is more definite. In the quantum space our research is mostly finding new interactions, not fundamental particles everyday. Energy & it transformations are the biggest truths eventually. To propel crafts capable of interstellar voyage, immense energy burst is needed for propulsion. We have seen no evidence of the kind of physics which will break relativistic models - and no material which can sustain the thermals in the process.

At the core of it, our chances to find another habitable world & intelligent species wherever they might be is rapidly reducing. Universe is expanding faster than previous estimated and probably double as old if you consider recent research. Our window of opportunity to establish contact passed probably before we came into existence.

It is like predicting we'll be able to detect God by advances one day. That supernatural being could exist - but most scientific evidence points to a hard no, given we already know it is a mental / emotional construction.
So where do we stay up to date with whether it's valid or not.
Assuming FTL is off the table, anything sent here will have been designed and launched with no evidence the subject planet has radars or air combat hardware. One should expect probes to have no air combat capability, and may not even bother to dodge a missile, even if they (incidentally) have very good aerodynamic performance.
A LOT of stuff got censored as "misinformation", that later got proved to be true

What that means is that people were sharing unproven things. Some of the things were later proven, and some weren't. Censoring everything until it's actually proven science is not a bad strategy when people are willing to inject themselves with bleach because they're so desperate for a cure.
> If Google doesn't want [Gmail etc] to be part of the open web they won't be

The point is not that Google cares about those sites - they don't. Those services are leverage that they use to control web standards, in order to enable their real cash-cow: AdSense. They will use their web properties to shove down our throats anything that makes AdSense more profitable, from the anti-adblock measures in Chrome to this one.

> If we're all dependent on them enough that that's a problem for us, then that dependency is the problem

I don't disagree - and I use Firefox, keep my important mail outside of Gmail, etc etc. But I recognize that many, many people don't, so the technologically literal out there have an ethical responsibility to push back against corruption of the open web.
At the bottom, it’s an address holding a program that can release funds to another address or a group of addresses (which may be wallets or other smart contracts) based on some predefined conditions.

There’s technically no limit to what you can implement, but there’s no killer app yet, and it’s questionable if there ever will be. For me, it’s mostly an interesting piece of tech to learn about.

Yes, probably

I worked in a SCIF for a short time for a defense contractor. It was a while ago, and I'm fuzzy about what I can and cannot say about how things worked in there, so I'd rather not say anything specific.

What I can say is that it's trivial to keep things you don't want leaving a SCIF in the SCIF.
