> But using LK-99 in a SC storage device is still theoretical.

Of course it is, any kind of use of this stuff is still theoretical. That's a content free statement. But GP was making the assumption that if it works it can be used for storage. But that doesn't really follow from the properties of the material as described so far. You'd need a lot more current carrying capacity for that to become a realistic possibility.
Is that signal not drowned out by the sun? Or are these bands where the sun doesn't do anything?
FFS, I hope the third world war is not coming.

Also, the US must know that it cannot win in any conflict with China regarding Taiwan right?

Taiwan is idealogical to China. Taiwan is merely a pawn in the game for the US. The US will bow out of a war for Taiwan within years but China will never give up - even if the war lasts 100 years.

Lee Kuan Yew (first Singapore PM) said it best: https://youtu.be/q_gr3dtBaic?t=682

Therefore, it's in everyone's best interest to maintain status quo and not to disturb the delicate balance of China/Taiwan/US. The Obama administration got it right. The Trump and Biden administrations have not. Nancy Pelosi flying to Taiwan looks great for her career, but terrible for everyone else.
Energy loses on wires are like 10% per 1000 miles.

But energy bill from central government is bundled with many taxes (like 50%). For example:

- CO2 emission tax

- BBC license (or local equivalent), like paying CNN every year...

- subsidy tax for oil energy complex

- loyalty tax for pensioners

- subsidy tax for current war policy....

The cost to compute these language models should eventually lower. Will OpenAI then release more frequently, or release larger LLMs? They'll probably to try achieve both goals in some proportion.

I might have misinterpreted something, but wasn't there an exposition piece from Isidore about how he could heal animals and humans before his abilities were burned out by exposure?

The quantities of energy released would heat up the material around it to the point that it may well lose its superconducting properties as well. Likely failure of any winding in such a setup would set off the rest as well unless there is a lot more separation. Mu metal has a relatively low saturation limit.

And that's before we get into the purely mechanical stresses created by such an event, which likely will destroy the vicinity of the carrier of the current.

> A higher level language might choose to always represent functions with function pointers

This is a dig at C++ in case anybody didn't notice. In C++ if I write three predicates X, Y and Z which decide if a > b, b < a and a == b respectively, for two ints named a and b -- their types are identical, X, Y and Z have the same type, the type of any function which takes two integers and return a boolean even though of course these are different functions.

Imagine if your other types worked like this. Oh IPv4Address and OldMacFileType both consist of four bytes, so now they're interchangeable and your code which takes an IPv4Address also works with a OldMacFileType. Very sensible.

As with many things in C++ this is inherited from C where it wasn't considered a bad problem because nobody has a decent optimising compiler on the PDP-11 anyway.

I have a $HOME/.gitignore that I use for this. (You can configure git to use that globally.) It's not a panacea, and I think other commenters are right that you should instead endeavor to organize things so that the project's own gitignore results in a sane workflow. But I think having permanently unstaged changes is worse.

In this version, in figure 6a and b the new log scale of the IV curve looks quite linear and increasing in the range of 150 to 250 mA. I thought that it should be flat if it was a superconductor (no resistance). Can anyone explain how that behavior still supports it being a superconductor?

They probably turn off the comments.
A whole lot of alerting is made better by generally considering whether to alert on large changes in in almost any kind of event, and sometimes even by measuring the changes in the rate of change, because it has a better chance of surviving "alert fatigue".

"That process that restarts spuriously once in a while has restarted again" stops being noteworthy very quickly if it's deemed low priority, and often even might lead to alerting thresholds being change because it becomes a nuisance.

"That process that restarted every now and again now restarts 5 time as often as it used to" on the other hand is a lot more likely to get attention.

No! That's not what I asked! I want to know how this specific, unique email address leaked, and afaict they're a legit business (like, Facebook levels of legit, not like a viagra spammer that works without accountability altogether) so it won't be through criminal means and they can just tell me. Instead they try to be too helpful / get rid of my complaint faster.

Maybe too tangential but the avoidance of answering the question in favor of "correcting" something (in their perception of correcting) reminded me of this

On the topic of alerts/notifications, does anyone know of a project or method for minimal selfhosted cross device notifications? Say I run a daemon on my home server which listens on a Unix or inet socket(s) for generic JSON messages which could come from anywhere, like an IRC plugin, bash command wrapper, or anything I can think of that I want to get a notification for (I choose JSON over sockets so that is quick to implement and can be easily embedded in whatever random environment that I can expose the socket to, even sandboxed ones with no internet connection). Then it exposes another socket where a daemon on my desktop and laptop can receive notifications from, and convert it to a notify-send command so that it's displayed on the desktop. And since the daemon on the home server saves the messages in say an sqlite database, my desktop/laptop can fetch messages and I can print a backlog if they were offline. Otherwise, I'll probably write something like this because I'd find it useful. Email seems to be the closest thing but I don't want to rely on an external service or run a whole internal mail server.
True. That's why we probably need another mechanism for incentivizing high-risk/high-reward/multi-decennial research. Perhaps, even if LK99 is not real, something interesting will mutate out of it: some kind of platform merging arXiv, Twitch, Patreon, making the researchers to be more transparent, more willing to share partial results, failures, and even be rewarded to fail. Some time ago had this "fail database" in mind, where one would upload all the data of the experiments that didn't work. I see there is a "FailCon" [1].

Hi HN! I'm Jarek, and I've built this tool that allows publishing .local domains on the local network using mDNS.

It also has a reverse proxy that handles HTTPS termination and port forwarding.

I'm working on adding more features, like an index page with all available domains or allowing proxy redirects, so you could redirect from HTTP to HTTPS.

Are you aware of any obvious issues with manufacturing Josephson junctions using photolithography? Like, would switching to an LK-99 or similar set us back to the 70s in terms of wafer density/size?
Indeed! Plus, whether something is surprising depends on what was expected in the first place. So you have to create some shared expectations first, right? Some kind of buildup?
I don’t really understand the concept of Jamstack or why it’s new. Isn’t it just HTML+JS (whether built with a framework such as Angular, React, Svelte, Gatsby, etc) that uses a backend api? What exactly are we discovering? What is the innovation here? Markdown?

A shade with a large number of fine slits that allowed light passage might work. selecting the right slit width to affect the optimal wave bands - is IR the main heat? Passage would create a number of divergent bands as that frequency passed. Particles would be unhindered for the most part = less solar stream drag. Even so there would be light drag - does the interference add a drag?
Even very thin screens mass significantly over a large area and might become hard to manage. A circular screen that was gradually spun up to make a spin-rigid disc would work if it was held rigid enough by a thin rim and the spin-up was gradual enough?

> If an operation results in conflicts, information about those conflicts will be recorded in the commit(s). The operation will succeed. You can then resolve the conflicts later.

I’m really glad people are trying this out. I’ve spent the last decade or so playing with collaborative editing algorithms. Ideally I’d like tools like git to eventually be replaced by CRDT based approaches. CRDTs would let us use the same tools to do pair programming. CRDTs also handle complex merges better (no self-conflicts like you can get with git). And they’re generally a more powerful model.

One problem with all modern text CRDTs (that I know of) is that they do automatic conflict-free resolution of concurrent edits. But when we collaborate offline on code, we usually want conflicts to show up and be resolved by hand. CRDTs should be able to handle that no problem - they have more information about the edit history than git, but doing this properly will (I think) require that we put the conflicts themselves into the data model for what a text file is. And I’m not sure how that should all work with modern text editors!

Anyway, it sounds like jj has figured out the same trick. I’m excited to see how well it works in practice. With this we’re one step closer to my dream of having a crdt based code repository!

The universe exists. It exists outside of our minds. We have the ability to explore and understand it, by choosing to focus our minds and engaging our rational faculty.

If we don’t have free will, then we can’t reason. If we can’t reason, then there is no such thing as evidence.

We do this much of the time in genetics, genomics, and neuroscience.

New technology;
Large set of samples;
Quantify x<1> … x<n> mRNAs, proteins, lipids, metabolites;
Estimate how units stick together (statistically or literally);
Develop a “theory” of what units and groups of units interact to account for and predict higher order phenotypes (risk of neurodegeneration; lifespan).

Data take precedence. Mini-theories of molecular and cellular causality are assembled with some basic brain power and yes—-a dollop of theory and priors—-on the back of a massive pool of well structured data.

Exploratory biology of this type is/was insulted using the terms “fishing” or “mere description” but with current high throughput and high content technologies should be considered research “trawling” and factory-level science; not a cottage industry of small labs. This new style of science can be highly effective in biology and in astronomy as we are learning from Webb.

But it bugs the hell out of some classically trained reductionists who demand that clear hypotheses should drive science forward.

Much of the progress in modern biology falls into this alternative almost hypothesis-free style. I would say “story-free” style of science. Too damn many story-tellers.

Contrast that to the before times where people, as you put it, bought whatever the dealer was selling.

It's descriptive, not normative.

Engineers build "useful models", scientists as a matter of fact, build explanations.

Whether those explanations prove useful is always an open question; newton's took centuries to have much of an engineering use.

Engineering is a kind of pseudoscience justified by its utitility -- if it's undertood to be mere utility, it's fine. But "engineering thinking" has taken over large areas of thinking, and it's a catastrophe.

You cannot build really new things by engineering. Engineering is just "statisticalisation" of new science; a simplification, an eloration, a proceduralisation. The science must come first.

When people are surprised they don’t put the information through their usual bullshit filters.

So people are willing to hear stuff that’s possibly utter garbage when it’s new and surprising.

The brain has to be open to novelty without dismissing it as untrue based on previous experiences.

So you can say things like “cut out everything that’s not surprising”, and because it’s new and surprising, your brain gives it a free pass: “hey that’s a new concept, could be good, let’s not put that through the bullshit filters just yet”.

A little more careful thought might reveal that the speaker is talking a pile of rubbish.

This explains why people love to go to conferences and rah rah events because they’re going to be fed new concepts they can latch onto without critical thinking.
Interesting see Asian scientists working together on this. Grinding it out over years - doing the work.

Meanwhile in Europe and America they sit in their expensive “centers” and “institutes” and ask for hundreds of millions more for their experiments which have resulted in incremental at best results. And that some had the gaul to mock the Korean scientists and their poor grammar and amateur labs.

And now the West will iterate on the breakthrough. The opposite of how it has been.
