> It may be that you simply need to construct the right geometry between nodes to get superconductivity.

I would say that the key thing is to construct the right interactions between electrons. That said, the geometry (or structure, as we would generally say in condensed matter physics) is one of the key parts of what determines the interactions in a material, so this is certainly one approach. In practice, it is difficult to tune the structure of most materials except by applying pressure, or by changing to a different (possibly related) material, so finely tuning the interactions by influincing the structure can be difficult (twisted bilayer graphene being a notable exception).

> Regardless of the underlying quantum mechanics, there's a large opening for experimental physics here. Are there edge effects, what about grain boundaries, etc.

I agree! Topological insulators and their surface states (which are in some sense "edge effects") is a pretty hot topic right now. Related to superconductivity, the research group I'm working in has been playing with introducing disorder to unconventional superconductors by plastically deforming them (i.e. squeezing them until we start to mess up the structure). Surprisingly, this has actually increased the superconducting transition temperature in some cases [0][1] (full disclosure: I'm one of the authors of this paper). As far as we can tell this "strain engineering" of the electronic properties of superconductors is basically a new subfield, so there's still a lot to learn. One of the difficulties is that in unconventional superconductors (which includes the high-Tc superconductors), theorists tend to prefer to work on idealized models of materials, since the calculations are difficult enough without introducing disorder, defects, etc. in addition.

To provide some rough intuition, I might point out that in order for a material to become superconducting, there must be some interaction in the material that allows the electrons to form Cooper pairs, and these interactions are more likely to occur in crystalline systems. In typical BCS superconductors for example, the electrons interact with atomic lattice vibrations (called phonons) to form these pairs. The work being discussed indicates that the relevant interactions are (magnetic) superexchange interactions between electrons are relevant in the cuprates (although I'd say more work is necessary to be sure). In both cases, the structure of the crystal lattice is important for determining how these interactions take place. That said, I'm aware of some amorphous (i.e. non-crystalline) superconductors, although I'm by no means an expert in these.

Another point to consider is that most chemically homogeneous solids are in principle crystalline, although in practice a chunk of matieral may be made of very many tiny crystals stuck together in random orientations.

As for whether nanoscale structure could have a significant effect, that question forms a pretty major part of my current research. The stuff I'm actively working on isn't ready to publish yet, but to repeat the example I mentioned elsewhere in the comments, my colleagues were able to increase the superconducting transition temperature of strontium titanate by almost a factor of 2 by plastic deformation (i.e. squeezing it until we start messing up the structure) [0][1] (full disclosure: I'm one of the authors of this paper). We think this basically occurs by modifying the nanoscale structure in a way that introduces mechanical strain in the crystal, and this strain in turn influences the electronic interactions in such a way as to locally increase the superconducting transition temperature. In a general sense, this is somewhat similar to the fact that in many cases, applying high pressure to many superconductors will increase their transition temperature.

> Net neutrality was about bandwith, not content

This is not true. Net neutrality is about service providers not getting to choose which services you connect with. If your ISP decided you can use Hulu but have to pay $10/mo extra for Netflix, that's a net neutrality issue. It's not about the volume of bytes. It's about who the bytes are coming from and going to, which is a content issue.

From Hashtag to Hate Crime: Twitter and Anti-Minority Sentiment [pdf]
The Florida law says a social media platform "may not willfully deplatform a candidate for office" and imposes fines of up to $250,000 per day on social media companies that ban candidates for elected office. The law also says social platforms "may not apply or use post-prioritization or shadow banning algorithms for content and material posted by or about... a candidate," and may not "censor, deplatform, or shadow ban a journalistic enterprise based on the content of its publication or broadcast."

If this is what the law is actually about, what's wrong here here? Do you really want corporates to decide what political views you should have access to? Every country has laws against hate speech or slander / defamation - if a politician or journalist says something inappropriate on these platform, it is the law that should punish them (even if the punishment is as light as forcing them / the platform to delete their post). (Related topic - even the Indian Supreme Court is currently deliberating on clarifying and enforcing laws on hate speech against journalist / editors / media platforms who have been increasingly indulging in hate mongering - "Where Is Our Nation Headed?", Supreme Court Expresses Concern About Hate Speech In Media, Asks Why Centre Is Standing As "Mute Witness"? - https://www.livelaw.in/top-stories/where-is-our-nation-heade... ).
I see where you're confused. You might well have a valid point if the discussion was about the Xcode IDE or whatever developer tools are supplied alongside Unreal Engine. That's not what the discussion was relating to. Per the great great great great great great great grandparent's post, the discussion was referring to "...the frameworks Apple develops that is available to you when you fire up Xcode..." https://news.ycombinator.com/item?id=32905694

Or indeed that post's parent, where a different opinion was offered about when a license for CoreML libraries was paid. https://news.ycombinator.com/item?id=32905596

Or its parent, the one which initially defined the scope of the discussion, which was "...Apple charging a license for the frameworks and tooling they provide..." https://news.ycombinator.com/item?id=32905555

Not about the Xcode IDE itself which I agree is free-as-in-beer. (Though others might disagree — an argument could be made that it was paid for the purchase of a relevant Apple hardware product; the fact that it wasn't pre-installed being a mere technicality.)
Yeah PortableGL will never be completely fully featured, not even for OpenGL 3.3 since I'll definitely never do the geometry shader and probably not the transform feedback. But specifically it'll never have the earlier immediate mode stuff, or some of the big 4.0 stuff like the tessellation shaders. I have been meaning to add the DSA functions where they make sense. They'd be really simple to implement.

Actually a few days ago someone sent me a pull request adding an interesting project to my README

https://github.com/rswinkle/PortableGL/commit/e0652b4dff266d...

So now if I were to try to sum up all the OpenGL software implementations I can think of,

TinyGL (and modern improved forks) = OpenGL 1.1-1.3 ish

osmesa = OpenGL 2.1 using Mesa 7.0.4's swrast

PortableGL = OpenGL 3.x-ish

Mesa = 2 software renderers still included, gallium based softpipe and llvmpipe
and I think one or both support the latest OpenGL 4.6 but I could be wrong. swrast and Intel's gallium/llvm based OpenSWR have both been removed from mainline Mesa, and the latter only supports 3.3 core-ish (https://www.openswr.org/)

I'm sure there are others out there. I've actually never tried to use "Stand alone" Mesa. I really should to see how it performs if nothing else, but I still say nothing beats the single header library for ease of use.

I don't get it, where's the bloat here? By using consistent rules across the language, Rust is requiring developers to keep less in their head. The author acknowledges this:

> Newer users find Rust easier to use and more consistent; they don’t have to learn the “edges” of where one thing works and where it doesn’t.

E.g. currently, Rust users have to know that if they want to use async on a trait, they need to add a dependency to the async_trait crate. Soon they won't.
Reminds me of a passion project I started in high school that went completely viral and took on a life of its own. Wrote a small script for my friends to check their AP scores a few days early. Required high schoolers giving clear text access to their entire CollegeBoard account so I could log on and scrape their scores. Somehow it got posted to Reddit and from that year on, grew wildly. Got to almost 2 million students checking their score in its peak year. It was immensely fun while it lasted (ran for about 7 years) and honestly I miss the thrill of it. CollegeBoard now releases all scores on the same day so the site is pretty much useless now. Definitely always looking to chase the thrill of that score release day again though.

Congrats on a successful end to a fun high school project! Stories like this are always fun to read.

There are software jobs that hire people who don’t speak Japanese.

Looks great but the API itself doesn't seem very innovative (which is probably not the goal anyway).

I'd personally be interested in a graphics API that do not try to render the whole buffer every frame, but update it given a list of changes (e.g. sprite moving/rotating). I believe that such approach could work very well for a 2D software renderer given the likeliness of spatial redundancy, and possibly for video encoding without going through a clueless encoder querying pixels (and having the ability to exploit hardware efficiency to decode/render the stream).

His point wasn't about ANY authority figure though. It was about ones with directly relevant expertise.

In his example, firefights are authorities... In regards to smoke and fire. Yeah I'm gonna trust what they have to say, both over what Bob has to say about smoke being good for my aura, and over anything that an irrelevant authority, like the town mayor, has to say.

Likewise back in February 2020 I found really great authorities on virology, a podcast with a rotating panel of 5+ virologists and people with other relevant phds, plus a doctor who headed up a COVID ward in NYC and started giving weekly clinical updates.

Naturally this resulted in me being called a sheeple who just did whatever the mayor (in the example in question) told him rather than following Bob, who must be true in saying smoke is good for me because he's wearing a lab coat and YouTube is censoring him.

The post title was originally taken from the article's title, "The U.S. Government’s Vast New Privatized Censorship Regime". Dang modified the title to "Censorship by big tech at the behest of the U.S. government?", editorializing it and adding the question mark. Dang objected to the words "vast" and "regime" in the title.

The article mentioned that 11 federal agencies were involved in asking social media companies to remove posts. I guess Hacker News needs standards mentioned in the FAQ about how many federal agencies need to be involved in an activity before it can be referred to as "vast".

Software often has built in back pressure. Most IO syscalls block, TCP surely does, so everything built on TCP does. Belt is memory. The full belt equivalent of software is OOM. If memory allocation can't be done everything comes to a halt. We could write software that instead of crashing just sits there until memory becomes available... It's the human scale circuit breakers (request timeouts) that cause issues. I guess one has to differentiate between batch processing software and interactive request/response style software. Factorio approximates the former, not the latter, but some of the underlying concepts are still the same.
Interesting idea.

To me, exoplanet surveys are one of the most exciting forms of science. I can think of no other thing that would bring us closer to understanding whether or not life does exist in our universe beyond us.

I've long held that it does, but it feels to me that belief is practically religious, completely unfounded. Combined with the fact that I think no other event will impact our world for the better more than knowing this universe has other life... I have my fingers crossed for the giant ground-based teles they listed at the end. Godspeed

As someone who generally prefers high level languages (Ruby, Python, JS) I'm enjoying Rust because unlike C and Cpp, I don't really have to care about memory. I don't want to spend my time thinking about memory allocations and deallocations.

Rust lets me focus on logic like a high level language does and the compiler tells me whether what I'm doing is memory safe or not. I'm vaguely aware of copying/cloning values, but Rust is pretty performant out of the box and I don't end up doing it very often.
Instant stats for your fantasy football league [Excel] [Python]
I just released version 1.5.0 of a new Python library called leeger.

This library allows you to take data from an existing fantasy football league and get instant stats from that league into either a Python script or an Excel spreadsheet.

This library supports multiple fantasy sites AND manual league data input.

The main idea behind this library is:

1. Load stats into a League object

2. Pass this League object into various library methods to extract stats

This currently supports the following fantasy sites for instant league loading:

- ESPN

- MyFantasyLeague

- Sleeper

- Yahoo

Any feedback is appreciated!

I have the college dreams fairly regularly. Usually they are about forgetting to attend class for a whole semester.

But my other recurring dream is about being an LDS missionary again. I think that experience in real life was even more stressful than college—definitely more guilt-inducing. In the dream I'm my current self—mid-40s, married, kids, career, atheist—and yet somehow the church has managed to coerce me back into the mission field alongside the 19-year-old true believers.

Almost every other former Mormon missionary I've asked about it reports having similar recurring dreams.
