“NTSB investigators usually wear sunglasses.”

Meaning that will likely be investigating your weather accident in the sunshine, so you could just wait a short while and fly in that good weather rather than crashing right now.
I believe it converts ePubs to PDF and so doing things like adjusting the font size requires rerendering the whole document.
> Onyx's pencil is decent, though I also had (and subsequently broke) a Staedtler pencil.

I use a remarkable pencil now which feels higher quality and works great (although is super expensive). My Staedtler also broke, so that's at least an n of 2.
It is not just money. Wasting fuel has a far more damaging impact on the nature than the negligible impact of having some metal tanks in the bottom of the ocean.
It is not like sea water is distilled water.
> Those countries have costs of labor far far below Western countries

That could be for some labor, but not all. The US is still in the game when it comes to automobiles. Well, when it comes to Tesla, it looks to me Tesla is eating everyone's lunch. The US is still in the game for other very high tech things, like military hardware. Or industrial trucks (think Caterpillar).

Where the US and other Western nations are a bit hopeless is the costs of megaconstructions, be they nuclear power plant or high speed rail, or simply skyscrapers.

But nuclear power plants could be more like Caterpillar than like "massive cathedrals", as you call them.
You just described hydroelectric power but with more steps and a much smaller area to catch rain.
if all the traffic is abusiveness why keep running the service
Plenty of non-technical people have already succeeded at trying Mastodon out, and the process for following people outside of your instance, while awkward, doesn't seem to be the impossible hassle some make it out to be.

Granted, there are a lot of rough edges around the UX of Mastodon but pasting a url into a form field is at worst mildly annoying.
If this is true, I wonder what it does with western corporate green agenda. There are huge money invested in it. Cheap superconductor would change a lot.

Similar situation was when EU banned incandescent light bulbs. Many manufactures (mainly western based) lobbied to have them banned, in favor of fluorescent light bulbs. However cheap LEDs were developed and eat their lunch.

If this superconductor is true, it means major power shift from central government, to local community! Distributed smart electric grids. Electric cars manufactured in a garage...
Just a heads up, Chrome flags your HN profile homepage as a "Deceptive site" !!
> The reason is simple, I can get my shit done a lot faster in MySQL.

and that's a perfectly valid reason.

unless you know for sure you need a specific tool, you should use whatever you're most comfortable with.
But obviously you can't exactly carry multi-Tesla electromagnets around. So no car batteries, much less phone batteries. Large energy storage facilities for grid power regulation, possibly.
This is not a bad model in my opinion. Actually, it may be even better than the average. At least, you could buy the expertise compared to a total lack of it.
You read a whole book, but can't be bothered to do a google search titled "watson and crick problematic"

Weird
I feel like one of the reasons is that it is a lot harder to fake a shaky video than a still one and he won't need to add in his voiceover in comparing to if he is directly recording from the digital microscope presumably.
They often try to get you out of it though, e.g. will reply with nothing but an attachment which is an image of their typed non-proxied email address they want you to use. (I guess Amazon filters it or tells them off if it's typed in the body of the email.)
Not saying that the vector space bit isn't neat, but it's called functional analysis because you can take limits of various forms and define (semi-) continuity, have completions of spaces, and all that has nice properties.
So to me, a crucial thing is that these vector spaces are indeed topological.
It's also worth contextualizing percentages. 90% still means 1 in every 10 parts fails.
This is why most "audiophile" stuff is redundant in my mind, a lot of people seem to act like valves have some sort of magic that we cannot profile and just reproduce in software.

But then again there's nothing wrong with people romanticising stuff as long as it's more "valves are cool because they're retro and nostalgic" over "valves are cool because they're objectively better".
We could do solid state current switching before transistors, with diode valves and whatnot. Transistors "just" made it more efficient.

Room temperature superconductors would not just just make a host of things more efficient, it would also enable devices that rely on high-strength magnetic fields to become much more widespread. For example, if you could remove the cooling requirements for MRI scanners then they could become much more usable "in the field".

Don't understimate the ability of the big energy corporations to find a way to profit from this. Greed always finds a way.
Use the API and set "always answer short" as system role. This has the side effect that you use less tokens. Compared to the 20$ for Chat-GPT premium, you also save some money.
> I have known several people who went into to psychology mostly to serve their own navel gazing.

Thats a lot better case then people studying psychology to become psychologists because they are trying to heal their own severe emotional and mental issues.
This can be said of all of philosophy (at least outside of the purely formal world of logic), not just the physical sciences. From that perspective, 'standing up to tests' is a poor way to evaluate hypotheses, except in comparison to all the others.

Paying attention to falsification also performs the useful task of pushing hypotheses into saying something definitive.

Science is much more than falsification, of course: for one thing, a falsificationist stance does not generate hypotheses on its own.

I'm not suggesting that all of philosophy should adopt falsification as a principle (and much less that it should be ignored if it cannot): ethics, for example, is a field which I think is important beyond what is falsifiable.
Is there such a thing as a material that behaves oppositely of a superconductor in the presence of a magnetic field? I mean a material that always attracts regardless of polarity?
How does lesics arrive at that figure? In my turbine design course we were taught that the absolute maximum is around 57% else the outgoing fluid won’t have enough kinetic energy to get out of the way of the incoming
To add a concrete example: Randy Hulet at Rice claimed BEC first, then Wieman and Cornell at Colorado, then Ketterle at MIT. Wieman, Cornell and Ketterle shared the Nobel. Hulet was passed over, because his data was judged insufficient to establish his claim.
> it means major power shift from central government, to local community! Distributed smart electric grids.

It doesnt even go that far. If it leads to cheaper, safer and denser battery tech, so many people will chose to invest in their own homes and not pay the huge fees for electricity and gas. Electric cars only sweeten the deal even further.
Or use the more dramatic `FailureAction=reboot` ;-)
Heroku notably does (did? It's been a while) daily restarts. I believe they started it to take away the support hassle of folks whose apps had memory leaks, but it's also a convenient mechanism to allow cycling the infrastructure without needing live migration.

Open-Source LLMs: Better Base Models
Good old polywater. Only this time they found something that all the scifi nerds can get excited about so the discussion is extra useless.
Well there wouldn't be fires that produce toxic fumes and burn even under water, but if the coil fractured in an accident all that energy would be released in a tiny fraction of a second instead of a combustion event that takes time. That seems bad...
I exaggerated a bit, it only happened with solar panels.

But it does gives you a similar feeling when you schedule a maneuver on a point where the planet/moon blocks your signal, and you only realize after it's too late

That's what I am thinking when commenters compare LLMs with humans. Humans got the experimental loop going through the real world, pure LLMs are brains in vats. They need experimental confirmation to become truly creative.

But on the other hand are the commenters who think AGI to ASI is going to take hours. When is there time to experiment anything? Even ASI needs real world confirmation to do research.
lol. I always thought it is some well known english metaphor that everyone knows, and the only interpretation I had was "blade runner" means running (no time to think) on a blade (very thin margin of error) and any misstep will be a catastrophe.
That's ANSI art, since it uses ANSI escape codes for colors. The two terms are often used interchangeably though.
The obvious one would be stronger railguns.
How to get ChatGPT to lie and give a false impression that it can be trusted?
No, they’ll explode unlike LiPo batteries. LiPo batteries merely catch fire.

An electromagnet, superconducting or otherwise, has large internal forces. If the support structure lets go, it will move. And, if part of the circuit becomes non-conducting, an inductive kickback will occur, generating enough voltage to (initially) sustain the original current.

You could cut a Li-ion battery in half, and the two halves will continue to store their chemical energy, at least until they burn up. If you cut an inductor in half (which is what this type of energy storage device is), that energy will dissipate very quickly whether you like it or not.
How do you think iron behaves?
Why, indeed? But don't think it's all the one way.

A particular reason that many men have difficulty with relationships is neglect - maternal neglect.

A victim of severe maternal neglect is usually also a victim of violence, either directly perpetrated by the mother or perpetrated by some other person at the mother's behest.

Irony: The victims of severe maternal neglect, just as the victims of male violence, understand the importance of kindness but have poor social function.

I think that until victim consciousness is forgotten, there's no chance of healing.

Therefore, in the fullness of time, all must find the strength to trust.

Why, yes, my dear fellow. That’s the name of the game.
I think that this is kinda like the lamp => transistor change. The immediate usages are not revolutionary, moving from lamps to transistors in amplifiers didn't change everything overnight. First products with transistors were barely better than the ones before. But oh boy did it create an infinite new horizon of opportunities on the long term

I don't really know whether the analogy holds, but I find reasonable reasons to think it does (we could finally get our low-voltage DC home \o/ maglevs \o/ routine/cheap IRMs \o/. that's just the "simple" applications that we can already foresee right now)
I think OP's point is that they're trying to think adversarially about whether such incentives exist, not implying that they actually do. It's a good thought experiment with a claim this large - to see how the claimant would benefit if they're fibbing, I mean.
Could you shield them with mumetal? Maybe make tiny arrays of thousands of them each with smaller atorage surrounded by mumetal to let them be close. That way if they break it is only those along the break that would discharge instantly.
This article seems mealy-mouthed. I struggle to believe the author's claims of fear when they also take shots at transgender people within the same paragraph.

If what they claim about the loudest voices on social media is true (which it is; they are quick to anger and punitive), I am not sure why you would intentionally bait them like that.
I don't understand; what single issue is it concentrating on?

CBDCs aren't really in the news either. So yeah. It's not like reporting about rather complicated foreign financial affairs that's detrimental to US hegemony is well funded or that there's a big audience to be reached.

AMD has won many contracts for supercomputers no doubt due to their lower pricing. But there’s a good reason why no one is buying them in droves for AI workloads.

Also:

And the different levels therein can help you think about your own systems, even if someone won’t crash a plane if your software fails.

A large passenger aircraft does not solely consist of Level A software. There’s plenty of not-flight-safety-critical software on any airplane you ride as a civilian passenger, but there is some Level A software that could cause the worst consequences if it fails.

Think about what pieces of your software are critical to your company/team’s mission, and which aren’t so bad if they fail. Not every line of code you write, or system you build, will wreak havoc on your company’s primary mission.
It sounds like that, but turns out that those are extremely hard optimizations to do as they require whole program analysis.
> I just realized! Cryptocurrency bros are pure function bros. Everything is pure and has no side effects!

That's a fair criticism to the extent that any theoretical decentralised ledger process pipeline touches the real world, but the extent to which they do touch the real world, and the benefits available from each of them varies enormously.

> Which puts a huge target on your head for any kind of real world malicious actor.

If the choice is between that and having a bank and its chain of dependencies as a tyrannical real world dictator, I'd rather have to deal with that target than be trapped in that tyranny. That risk can be mitigated, it can be compensated for, structures can be erected to address it.

If you're slave to a tyrant, you're simply immediately subject to whatever their whims are. That is utterly unacceptable, even if it does theoretically reduce some risk for some people sometimes.

In a society that was not a cyberpunk dystopia, the price for instruments that allowed you to circumvent said tyranny would probably be much lower than it is. But this is not that world, I guess.

It’s not difficult to provide a bad experience regardless of technology. But if your baseline is slower and messier, it has a significant impact on your average application. I can also tell you bad personal experiences, but how about not making it personal? Thanks
At the frequencies computer chips operate, it acts more like AC. Sure, you place some nice bypass capacitors capacitors very close to the chip so you can feed it nice clean DC power, but when you start switching those transistors in the GHz range, the signals inside the chip rapidly start to look a lot like AC.

You see the same thing with external signals, like a connection between CPU and memory. Operate the bus at 1MHz and it is effectively DC. The signal has a wavelength of 300 meters, so when the signal travels a distance literally two orders of magnitude smaller across your motherboard the AC behavior is negligible. Operate that same bus at 1GHz and your wavelength is down to 30cm. Got a 40cm-wide motherboard? Better treat it like a transmission line or it isn't going to work!
Can we have a link to the original video? The twitter thread links to a video of a screencap.
Yeah, it's good to see that because there were some concerning signs in the last day or so.
Theoretically, could/should we use these for signalling as well? Small strands of superconducting wire instead of fiberglass?

I'm aware of that.

But if I was an early-career researcher looking to establish myself, secure funding and maybe a tenure-track position, and I had a nobel-prize-winning discovery up my sleeve, I can't imagine many things that would take precedence.

I mean, obviously whatever happened happened. It just seems strange to simultaneously claim to have discovered something 24 years ago, and to have been rushed into publishing prematurely.

I've been getting into parkour recently (as in, watching videos of it, not actually participating myself), and it does make me look at urban design and street furniture with a new eye. (The people who actually do it have that effect tenfold, of course.)

What Happens If We Add Fractions Incorrectly? SoME3 [video]
Another example from Europe that I've just seen: in Vienna's Shoenbrunn Palace[1], pretty much all grass in the gardens is off limit (but most grass in the public parks in the city is open). I suppose that makes sense because that garden is specifically made to look splendid, not for people to picnic on, and given the huge number of tourists coming all the time, allowing people to walk on that grass would quickly turn it into mud.

let me rephrase that, wolfi is an oss container image distro without an image, you get to pay us for the image. but here's a our tooling cause we like to call it oss, have fun building. either have those oss images on a non commercial registry, or let's stop misleading folks about what this is, aka pay to play/use oci images. that all wolfi docs / blog posts reference a commercial registry while touting it as oss, is the definition of bait and switch.
What do you mean by lamps? Electron tubes?
For something that has any expectation of fairly high uptime, I think the more important aspect here is failover (either due to actual failures, or due to maintenance) not specifically load balancing, although at this level of traffic, it's definitely helpful to be able to spread the traffic over numerous internal resources rather than relying purely on vertical scaling of the backends.

If you're able/willing to manage the LB systems yourself, generally I'd stick two balancers (running HAProxy) in front of the application servers, and do IP failover between them.

If your service uses internal IP connectivity to e.g a database or redis cluster or what have you, I'd generally have each of the balancers configured as a primary for either public or private traffic, and as a backup for the other traffic. If your service doesn't use a clustered database service or anything like it, you can obviously omit the config that balances private traffic, and it's possible this aspect is "taken care of" for you using k8s.

The exact method of IP failover is going to depend on who is hosting your machines and what their network is configured to allow (i.e. Linode previously supported VRRP, but now do not, and BGP is used instead). AFAIK none of the "standard" IP failover techniques will work in GCP/etc. Whether this is due to legitimate technical limitations of business/profit-driven decisions is left as an exercise for the reader to further analyse.

Also consider that if you're using managed k8s, the provider of that service almost certainly has a managed load balancer service. I'm not sure what you mean by "all managed load balancers will cost a ton" - Linode's balancer as an example, has a $10 monthly flat fee.

You mention "5Gbps to the service" - does that mean the data is mostly inbound, or did you mean requests result in outbound traffic averaging 5Gbps?

It's not a coincidence that GCP's load balancer will charge you, according to my calculation and their pricing, $18 per hour at 5Gbps sustained - that's the entire business model of 'big cloud' businesses. Have you looked at any providers besides GCP/AWS/Azure for hosting this service? Some guesses about what you're using from your post + reply below plus some quick calculations suggest this would be orders of magnitude cheaper to host on Linode, or a similar "not AWS-alike" provider.
There's A6000 Ada for that (you can rent servers with 4xA6000 at Lambda Labs). Moreover, 4090 has only 24GB memory, H100 has 80GB.
Looks interesting. Unfortunately doesn't support signing commits - apparently it's possible via "jj export" and using classical git:

> For example, if you could remove the cooling requirements for MRI scanners

But MRI is almost the only tech we know today to be affected by this (and we could count maglev as well, but I don't think it'll change the landscape too much here, as the deployment of high speed trains un general is less technologically limited than it is by limited politcal will).

And even for MRI, room-temperature SC is only a big deal if you can find zone that works for high current, wich isn't the case here son far.
You sleep during the day?
A colleague recently showed me the coil of a broken superconducting magnet after it quenched. There was an easily visible rip in the structure, even though the whole thing was enclosed. It must have at least had enough kinetic energy to tear the metal apart.
I have a question for a cloud person, maybe you can answer it.

When it rains, where does the latent heat go? The latent heat of evaporation (or condensation) is absolutely huge. Condensation means heat is released. I did a back of the envelope calculation. 2 mm daily rainfall x 500 million km2 = 10^15 kg; each kg of water holds 2.26 MJ of latent heat, and there are 86400 seconds in a day, so that's 26.15 W, so overall 26150 TW. The Earth receives about 173000 TW from the Sun, so this is about 15% of the energy received from the Sun. Obviously, not all the 15% goes out to space, but about how much does go to space?
