Sometimes you have changes that are permanent to your repo (ie local workflow), that you always want to keep locally, but never push to the remote.

In git you would always leave the changes unstage, does that mean with jj you would always have to remove them before pushing? I haven’t found an answer on the linked page.

Side note: I really wish git had a way to mark commit has ‘no-push’ so they never leave your local copy, as an upgrade of the unstaged workflow.

Superconductors allow creation of non-chemical energy storage whose capacity is only limited by storage's mechanical resistance from being crushed by its own magnetic field and which has nothing like "finite charge-discharge cycle life limit"

Additionally it has no internal resistance, so you can charge such battery virtually immediately, but you can also discharge it immediately. This will be important for energy based weapons.
Only some applications require flexible cables. All of "my" use cases should be fine with using ceramics. I really don't think this will be the problem ...
One of the reasons we can't build a practical fusion reactor is that we need to make very powerful electromagnets. Doing so requires a lot of electricity going through big circular circuits. Doing that without a superconductor creates too much heat and the whole thing melts.

They're trying to build them with existing superconductors instead, but those require super cold temperatures or super high pressure.

This is (maybe!) a superconductor that's cheap and exists at normal temperature and pressure.

It's got some deficiencies that would prevent it from being used in a fusion reactor, but it's existence may teach us how to build a better one that will work.
> So in theory you could have a ridiculous computer that runs 1000GW of power through it without heating up.

I touched on this in a previous thread[1], but superconductors only stay superconducting below not just a critical temperature, but also below a critical current density and critical magnetic field strength.

These limits are different for different superconductors. It could very well be this superconductor has really high critical temperature but really low critical current density, in which case you can't have lots of current at zero resistance.

We are still at the if-it-is-real stage. I would not take any wagers that the generation one release is indicative of an industrialized product performance.
Hydrogen best case density is ~ 2.5 kWh/kg, definitely not that great considering this is in its liquid form. To stay in that form, you need to cool them to ~ 20˚K, which is about -253°C. Also, because the molecules are so small, the tank needs to be almost perfect. Even the crystal structure of metals is eventually penetrated by hydrogen.
Hydrogen has many sensible uses in the production of many goods, filling powerful electrical generators etc. It would be great if we could produce it economically in a renewable fashion.

Actually, there are many carbon free fuels. It is hard for any to use as jet fuel.
An example fuel that has much better properties than hydrogen is for instance sodium. Making a sodium fuel cell does not need any rare earth metals such as platinum, sodium is solid at room temperature, does not produce any fumes, better energy density than liquid hydrogen, the resulting NaOH sodium hydroxide can be recycled into sodium (with hydrogen as a byproduct) by the Castner process. Hard to say, if this could use the water vapor present in the atmosphere, if it did, you would also have to think about what to do with the caustic hydroxide solution. Probably, that would be neutralized quickly in the atmosphere but at ground level or above cities could "raise eyebrows" even though burning leaded petroleum in aviation still seems to be a thing...
There are citations both for and against falsificationism at the Stanford Encyclopedia of Philosophy[0]; quoting:

"Popper’s demarcation criterion has been criticized both for excluding legitimate science (Hansson 2006) and for giving some pseudosciences the status of being scientific (Agassi 1991; Mahner 2007, 518–519). Strictly speaking, his criterion excludes the possibility that there can be a pseudoscientific claim that is refutable. According to Larry Laudan (1983, 121), it “has the untoward consequence of countenancing as ‘scientific’ every crank claim which makes ascertainably false assertions”"

From the citation on Hansson, the abstract[1] reads:

"...Furthermore, an empirical study of falsification in science is reported, based on the 70 scientific contributions that were published as articles in Nature in 2000. Only one of these articles conformed to the falsificationist recipe for successful science, namely the falsification of a hypothesis that is more accessible to falsification than to verification."

i guess the voltage would be rather low... but current capacity might be enough to melt your drill bit, if you decide to drill hole through both of the electrodes :-D
I am part of the architectural uprising in Norway. In order to make more walkable and livable cities, the cities also need to be more attractive and aesthetically pleasing. The last decades, small towns in Norway and rural areas has become hideously ugly. More people are getting angry, as they see high rise housing and shopping malls pop up everywhere. Suburban sprawl in Norway is the worst in Europe. The architectural uprisings fight for more aesthetically pleasing architecture, is interestingly more popular among young people under 30 here in Norway.

The Higgs discovery was by ATLAS and CMS experiments (thousands of people) but the Nobel prize went to the theorists.

Yes, and to have alerts, I have resorted to write my own small tools [0][1] at the end of the day. Railgun proved to be very useful, but for smaller things, I'm writing the second one.

Important to distinguish Bayesian epistemology (the idea that knowledge comes from induction) from Bayesian techniques in statistics. Karl Popper’s epistemology (critical rationalism) refutes the former, but does not mind the latter.

Popper would agree that Bayesian techniques are useful (and even powerful) tools in statistics and practical problem-solving. But he would say that Bayesian ideas are insufficient to understand how knowledge grows and progresses. From a critical rationalism viewpoint, knowledge grows through conjecture and refutation - the proposal and testing of new explanatory theories.
Bayesian statistical approaches can be part of the toolkit to falsify those theories, but they can’t explain how they come about, so they aren’t adequate as an epistemology. Popper’s critical rationalism may not be entirely complete, but it seems far better as a starting point for explaining how we get knowledge (which is what an epistemological framework needs to do) than Bayesian ideas about measuring truth statistically. Major breakthroughs like relativity and quantum entanglement are evidence for this: they required conjectures that at first seemed at odds with what we had observed. Physicists had to follow rational theories down very strange paths before any empirical confirmation, eventually to create new explanations that allowed us to model and predict distant cosmological events that had previously appeared random to us.

If anyone is interested in these ideas (which are still fairly new to me; sorry for anything I’m expressing poorly), I highly recommend reading The Beginning of Infinity. It is an exciting, wide-ranging study of Popper’s epistemology by the guy who ‘invented’ quantum computing. It also discusses the ‘many universes’ theory, which is fascinating.

Not only that, but barring babies with compromised immune systems, you really don't want to get too crazy about sterility. They need to be exposed to pathogens in order to develop immune responses!
Intense pain and the spiritual displacement it causes.
Also, btw, this one is fun:

It would, if the enlargement is not by linear scaling but instead produces a shell around the object at some distance from the surface. The inverted-normal shell of the ear would then occlude the body behind it, while itself being occluded by the slightly smaller ear, producing a contour line.

They should make a theme park of objects that you're not allowed to climb but which you then still can climb because it's not enforced.
This is no longer true - Gallery 3 screens are ACEP that can refresh in a second and a half. For instance the Bigme Galy is an e-reader based on the Gallery 3, and [as you can see](https://youtu.be/V3jmmo23J5w?t=1202) is perfectly functional for interactive use.

It's still slightly higher than monochrome, but only by milliseconds. IMO, fast-ACeP is the future and will eventually kill CFA/Kaleido.
It sounds like you don't know the history. They were doing other unrelated things in the meantime, not working in this.

Could you, ehm, just make it a into a fine powder, then use a magnet to separate the powder that levitates from the powder which doesn't, then collect the levitating powder and stick it back together... with glue?
I’ve been to 41 countries, and I’ve learned the USA’s precise address locations is more the exception than the rule. I expect the courier to have my number out of necessity. I’ve had packages shipped to several countries, and often the most precise address I can provide is “the blue door right of the cheese shop on $STREET”. Dubai is interesting in that it has fairly good addresses, but uses nearby landmarks instead of postal codes. “123 Sheikh Abdul St, Dubai, next to the Desert Cinema”.

Seeing this some non technical people will try out this Mastodon thing. If they can get past the initial hassle of choosing an instance to sign on they will try to 'Follow' the BBC account on the social.bbc instance, only to be greeted by this user friendly process:

1. Finding the string you have to search for of the BBC account

2. Opening up their home instance

3. Going to the terrible search menu

4. Pasting the identifying string of the instance

5. Hoping the search doesn't bug out

6. Clicking follow and hoping the request doesn't bug out and remain in pending for months (yes, this happens)

Instead of the process on 'traditional' social media which is:

1. Click the big shiny button

Why they haven't yet fixed this glaring UX flaw using something like URL protocols is astonishing. I guess this is why technical people shouldn't design products. Nobody cares how it is built if it offers only friction to the end user.
Sadly there are lots of basic must-have tasks that Linux distros simply do not support out of the box. It's not so much an OS as a kit for making operating systems. Backup is another.

Here's how I set up email monitoring of systemd services, for anyone who wants it:

https://gist.github.com/mikehearn/f1db694f24eaa05c753e5a7598...

It consists of three parts. Firstly a shell script that will email the unit status colorized to your preferred email address. Secondly, a service file that tells systemd how to call it, and finally, an OnFailure line in each service that you want to monitor. You can use systemd's support for overlays to add this to existing services you didn't write yourself.

You also have to make sure that your server can actually send mail to you. Installing default-mta will get you an SMTP relay that's secure out of the box but your email service will consider it spam. If you use gmail it's typically sufficient to just create a filter that ensures emails from your server are never marked as spam.
Just for fun:

Volume of ice = π * (radius)^2 * height

where radius = diameter / 2 and height is given in meters.

Volume = π * (10m / 2)^2 * 2700m

Volume ≈ 354,177.66 cubic meters

The density of ice is approximately 917 kilograms per cubic meter.

Weight of ice extracted = Volume * Density of ice

So, the weight of the ice extracted from the hole is approximately 324,856,152.42 kilograms.

Greta must be fuming.

In all seriousness though, ice cores are a few inches in diameter, not 10 meters. Unless they take one of those tunnel boring machines and send it vertically down through earth.
Would be great if they had stuck to typesetting Math instead of inventing a new programming language. Lot of scope creep there. Who wants to learn yet another programming language ?
You have weird ideas about people.
Remote Attestation TLS (RA-TLS)
I would assume there would always be the expectation that you either use Jujitsu as a frontend to a git repo, or have a complete Jujitsu based remotes.

If you're going to work on and contribute to a project that is already using Jujitsu, it is reasonable to expect that you'd adapt your workflow to the project itself and not the other way around.

It's hard to know what this might be. I wouldn't assume it's a lack of perfectly CPU-optimised native UI code when it could be all manner of things.
They are making more samples (bigger ones to test resistance).

My guess is that they already broke it to pieces and this one levitates slightly. Until they get more samples they will keep this one intact.
A couple of immediate thoughts:

1. In many cases the books were published by Microsoft Press, so the company benefitted financially as well.

2. The engineers may have a defences in not being given time to document better initially due to project deadlines beyond their control, and in the work being signed-off at the time.

3. Some of both the above mixed with other reasons.

Someone you're copying from during an exam is there for the whole duration of the exam. Neither are there "for you" though, they're just there.

No, because a statistical model isn't thought. You can get something out of it, just like you can get something out of watching a movie that was made without the knowledge of your existence, but that something is not conversation.
> Because of the ADA, which is a damn good law, one of the very few things America gets right that the European democracies have not caught up with yet.

I'm not getting the logic here. So because a small number of people can't benefit from a fun jumping walkway the 95% don't get to benefit either?

That seems incredibly spiteful.
They don't say you shouldn't optimize at all. But before you do, check what your performance bottlenecks are, take measurements and start from there.

I would expect that, in the best case, this would give a gluey clump of stuff that can be levitated.

They are daring them to repo the property. It’s a secured loan but if the thing it was secured with is no longer valuable… probably this ends with millions being removed from the principal of the loan and payments resumed
What isn't true? Is both the average and the variance of IQ in men/women identically equal? Why would we even expect it to be?

Is the likelihood of risk taking behaviour identically equal between men/women? Why would we even expect it to be?

Is the likelihood that a man/women will be identically equally interested in a career in the hard sciences? Why would we even expect it to be?
One of the things that's most annoying to me is that you have to walk on eggshells to get it not to interpret what you write as challenging it.

I forget the situation I had a while back; I asked it to do something with which I wasn't really familiar (maybe it was translating in a foreign language). I asked it, "Why did do X instead of Y?" And instead of explaining why it did X instead of Y, it said, "I'm sorry, you're right; Y is a better thing to do." No! Maybe Y is better, but if it is, I still don't know why!

That was probably GPT-3.5 though; I haven't experienced that in a long time. (In part because a lot of my system prompts include "If any questions are asked, be sure to clearly correct any errors or misconceptions" -- i.e., don't assume the questioner is correct.) But also because I've gotten in the habit of saying something like "Can you explain why you chose X instead of Y", or even just "Would Y work as well?" Those are harder to interpret as implicit challenges.
Even in well funded fields, nobody wants to give away easy follow-on publications to other labs.

Oh, you want to document things well enough that people can build on your work and give you citations eventually. But if you've just demonstrated a groundbreaking technique for Foo and the obvious next step is to test it on Bar, you've got an opportunity to get your lab two papers instead of one, and all you have to do is less documentation?
I thought that was the switching loss of the transistors themselves, not the interconnects?

I find myself in a bit of a quandary over the upcoming Nintendo Switch release slated for this fall. Having navigated my way from the Switch Lite to the standard Switch, and now being confronted with the OLED model, I can't help but feel a sense of continuity, rather than any groundbreaking advancement. I revel in the games, no doubt about it, but the purported 'improvements' haven't sparked any significant eureka moments for me. Each upgrade has cost me an additional 100-150 euros, yet the experience, albeit slightly enhanced, doesn't seem to justify the price tag. I'm left questioning, is the elusive "it's better" worth it? What are your thoughts, fellow gamers?
I'm not hearing much argument for why I might be wrong, other than pearl clutching, tone policing and guilt by association

The magnetic field of a superconducting electromagnet contains a lot of energy because the field can be very strong with a large cross section. It’s the conjugate of a capacitor after all, it’s just that the energy density of normal inductors is much lower than that of capacitors. Using a superconductor also avoids resistive losses for (dis)charging.

(Inductors are very frequently used for very short-term energy storage (~fractions of a millisecond). For example, all energy output by a flyback converter was briefly stored in the transformer’s magnetic field. Unlike a regular transformer/forward converter, where the magnetic field is just a side effect of coupled inductors, so none of the energy is stored in it.)

Most of them, just depends what you want to do.
Ok, TIL that the high capacity of a supercap doesn't translate into a ginormous voltage (Wikipedia: "A supercapacitor [...] is a high-capacity capacitor, with a capacitance value much higher than other capacitors but with lower voltage limits"). Good to know...
Basically, just push more and more electricity into a coil of superconductive wire. Because the wire has no resistance, the electricity just loops around forever.
Use the API or playground, delete the erroneous assistant message and refine the instructions/last user message.

E.g. append: "Remember: Do not do this stupid thing you are likely to do" (and I saw you doing before. But you now have no memory of that...)
