This is probably the most stupid question to ask, but while were are still trying to confirm superconductivity instead of understanding its precise mechanism of operation, why the focus on levitation on band structure to confirm the news instead of just "yep this chunk has actually zero Ohms"?
Wow, somehow I wasn't aware of this game, looks quite intensive and inspiring.
Yes. It is intended for users who are using Chromium-based browsers or others that still will support WEI. While you're right that if you're against WEI, you are more likely to opt for a browser that doesn't support it, not everyone may have that option or preference.
As far as I know, no site has implemented this crap yet. So, while we believe the script would be effective based on WEI explainer docs, its real-world effectiveness is currently uncertain until we see actual implementations of WEI in use.
Why all solopreneurs should write a journal
You’re either too young to remember or creating a non-existent history of what life was like before same-sex marriage was legalized. This is not a comment on anything to do with gay rights but more just a matter of fact: pre-Obergefell life was VERY similar to life today. Gay people still lived together, still went on dates, and held hands. They weren’t run out of town for being gay. There wasn’t rampant homophobia everywhere you turned and anti-gay gangs roaming about enforcing the social order. They just couldn’t enjoy the legal benefits of marriage.

If anything, things are probably worse from a sentiment perspective for gay people now because a bunch of heterosexual liberal white women use pride parades to act completely shamelessly under the guise of being warriors for a movement they aren’t otherwise a part of.
Also in ethnically homogenous countries?
One of the reasons for choosing Nim was the ease of getting a production ready web backend. For the core part of managing the backend we are using existing Nim libraries [1], and they are easy to expand and work with. I cannot give you a comparison with Go since I haven't managed that large Go projects - but for Nim we are all into the async and threading. I think the channels within the threading is hardest part in Nim, but work is being done it.

> Again, the argument is that _without_ shame and a shared social contract, the replacement by explicit state authority to moderate harmful behaviors drifts towards fascism.

The argument is plain wrong. Fascism and nazism were driven by fear and shame from day one. You can find transcriptions from early talks from the dictators and others.
> UFOs could be coming from extra dimensions

I somehow find this perhaps more believable than the alternatives of (1) civs out there having FTL and not colonizing the Galaxy to the degree that we would detect it or (2) them coming here at sublight speeds to do the described UFO things.
I worked for a while in the military industrial complex. The only legal outlets for modifying your reality were alcohol and sex. So there were lots of people who drank heavily and swapped wives. They were quite open about it, because keeping it a secret could cause you to lose your security clearance (it made you blackmailable). They were also very accepting of whatever your skin color was, because the military demanded it. It was something of a shock moving to an industry job and discovering that racism still existed.
It means we need to stop bringing up neuroscience in contexts where it has absolutely no relationship with what we're talking about.
It’s also a tiny country which happens to be a dictatorship where these drug laws are fairly easy to enforce.

Also I’m not convinced that executing people for non-violent crimes is a good tradeoff in the first place.

"zero ohms" is very tricky to measure because of contact resistance: your probes aren't superconducting, and the thin contact surface between your probes and the metal itself isn't superconducting either.

Whereas the Meissner effect is unique to superconductors. It just has to be distinguished from diamagnetism, and there are materials which are strongly diamagnetic but not superconductors.

I was delighted to see this headline and post. The remedies he suggests are unfortunately 86% marketing! Only one line suggests real work, but done by others:

"Find someone that can poke holes in your work, then go address them."

The underlying issue is widespread in OSS projects. Increasingly it is all about features (for which those who are paid to "work" on projects are rewarded). Others spend 10x the amount to fix the features or leave the projects or are driven out by the corporate developers.
Here is their own article on the incident: https://home.cern/news/press-release/cern/cern-releases-anal...

Doesn't sound too spectacular but it took them over a year to fix all the damage.
I think there's something in between the polarity you've got there, something like "tough love". I think too much policy is based on emotional ideas, instead of seeing 'kindness, support, and re-integration' as ends of those ideal policies. People cannot just heroically decide to be kind in the face of an overwhelming issue.

I also think there's a point where things have slid so far that we need some measures that appear inhumane on the surface, but solve the problem more meaningfully. I think of the protesters in Toronto hoping to permanently protect the tent villages established in Trinity-Bellwoods inner city park, even blocking the police from clearing people out of their "homes". If we go on with policies like "give out free tents" that are the epitome of band-aid emotionally driven ideas It's hard to see how we aren't simply incentivizing the problem to grow.

It's as though some people genuinely think the permanent slums as in india or brazil are a solution and not a problem.
Thanks for that info. I was aware that birds were sensitive to many chemicals but not to that degree. However, it likely explains an incident that happened some years ago. We saw a canary aimlessly hopping about on the nature strip outside the factory where I was working and we figured it was someone's pet bird that had gotten loose.

Anyway, a colleague caught it in his hands which was surprising given he wasn't that nimble. The bird didn't appear the least bit sick and he likely caught it because it was used to having people around. The aim was to return it to its owner if we could find the person (it was an industrial area but there were many homes in the street). Incidentally, we weren't bird owners so managing a lost bird was a new experience.

We borrowed a largish birdcage that hadn't been used for years, cleaned it up and bought special canary feed and a cuttlefish etc. from the local pet shop, and we hung the birdcage and canary in a partly-shaded area without direct sunlight just outside the factory door with a sign on it to the effect 'do you own this bird?'. Every night we brought the cage in and covered it with a sheet just as I'd seen my grandmother do with her canary when I was a kid.

This went on for about two weeks or so and the bird seemed well and healthy—and we'd gotten quite used to the bird happily chirping away outside the front door. One day I noticed fruit flies around a garbage can inside the factory area and sprayed inside it with normal household pyrethrin-type insecticide which is usually pretty innocuous (at least to humans). Moreover, I was well aware that the canary was in the factory albeit 40/50 feet away so I was careful and deliberately confined the spray to inside the garbage bin.

Next day when I came in I found the canary dead at the bottom of its cage and I was considerably upset over its death as I'd not only gotten used to having this cute little creature around but it was immediately apparent to me that my spraying could have been the cause although I just couldn't see how such little amount of spray would have traveled that large distance.

It would be interesting to know exactly how sensitive canaries are to pyrethroids and how others manage to keep their pet birds safe in these circumstances.
I mean if everyone did drugs but everyone never noticed it then, did they actually use drugs? If there's nothing observable from someone that is supposedly drunk, then who cares?
Because without this criteria our number of applicants for junior positions would be unfeasible to review and process. It already is, frankly, and I've heard talks about narrowing it down further to only people with masters degrees just to bring the number down to something that can actually be reviewed by a human.

It's a tough line to walk - as a hiring manager I'd love to talk to every promising candidate no matter what education they have, but equally I also wouldn't want to do the job of recruitment where they take weeks just to sort through the absolute flood of applications that we get.
Easier in the best case and much harder in the worst, when your lack of thinking is an issue (which it definitely will be unless you're prepared to use more of the machine for no reason). Simplicity is not about what's easier to use, it's about how you interface with something, how simple and straight forward that interface is to use, how many things are implicitly or explicitly affected by that thing, and so on. Automatic memory management usually implies an assumption that allocations can't fail, memory is infinite, etc., so the assumptions and complications are many. It also adds more code you didn't write and have no direct control over, which complicates your problem solving in many ways.

GC or other automatic memory management is only easier if you have absolutely zero care for resource usage. RAII will oftentimes lead to single allocations and deallocations, for example, unless you take care to not have it be so, which is an immense waste of resources.

It's fine if you don't care and you know that that's going to produce slow, bad software, but let's be honest about that instead of saying you can not care and everything will be fine.

Yes! This is what I call stopping at 90%!

The remaining 10% is far more difficult to track and often has no clear stopping point. It's often better to skip the last 10% and move on.

You all work on one shared main branch, without any feature branches? Isn't it horrible to have other people half-finished code in the code that you are trying to work with?
I don't see it as confessing their sins, more like "FYI, I used X tool to help me with Y" like you'd see "Page generated by Z" in a footer except in a header since it's related to the content itself.

Hello everyone,

I hope this message finds you well. I've been working diligently on developing an app, and I'm currently at a stage where I believe the community's input would be immensely beneficial.

As a solo developer, I've managed to carry out all aspects of the project independently so far. However, I believe that having a fresh set of eyes to provide feedback would greatly contribute to enhancing the final product.

I'm particularly interested in your thoughts regarding its functionality, usability, and overall design. Your expert opinions and constructive criticism will be greatly appreciated.

Please, when you find some spare time, take a look at my work and let me know what you think. Your feedback will not only help me improve this app but also grow as a developer.

Thank you in advance for your time and consideration.
People think of "Tuesday night" as the night that falls at the end of Tuesday, however the majority of it from an astronomy perspective tends to fall after midnight (particularly with daylight savings time), hence it's referred to as the 2nd.
Ah, right, I didn't remember that.
> Office equipment doesn't really have "transformers" anymore, everything uses switched-mode power supplies. The way they work, is that they have an output buffer (a capacitor or inductor) and rapidly turn a switch on and off to keep that output buffer at the right level...

Overwhelming majority of mains-powered devices does, in fact, have a transformer. It is part of a switched-mode power supply, though. The only devices that do not have one are those that are fully enclosed in plastics and user can not under any circumstances come to contact with any of the conductive parts. Typical example would be a LED light bulb or wall-socket powered WiFi repeater (without RJ45 port).

It is pretty hard to create a transformer-less device using plain rectifier/switch/capacitor topology. The biggest issues obviously are the high voltage before the switch and dead time when the mains voltage drops near zero 100 times per second. Most switch ICs made in the "west" cannot go up to 325V and are thus usually used with a transformer to step the voltage down below 60V. If you get a Chinese chip that can work off-line (as in directly with the 325V mains voltage), such as KP1063 <https://datasheet.lcsc.com/lcsc/2103171532_Kiwi-Instruments-...>, it still needs an inductor to bridge the mains dead time. This is incidentally done by the transformer in traditional power supplies. Capacitor would have to be huge to smooth over those for any significant power draw.

> If we increase the voltage across the wires to 120V and down-convert that to 12V at the computer we'd only need to conduct 1A and the wire loss would be 0.5V, which at 1A is a power loss of 0.5W. That's completely acceptable, and because the computer down-converts anyways we don't really have to care about it getting 119.5V instead of 120V either.

We could use 48V, which would bring the cable losses to about 3.3W (for those 100 ft). Or maybe instead of wiring from the mains box, we would place transformers along the wall sockets. Some new installations already do that and install charging USB ports. USB-PD is now specified up to 48V / 5A.

I think that we are already seeing devices abandoning the traditional DC connectors in favor of USB. A lot more people now have a large bank of charging USB-A and USB-C ports on their desks. Some vendors already integrate them in extension cords. It won't take long for LED lamps to come with an USB cord and an optional mains/USB transformer SMPS ("phone charger"). Laptops are already charging (and docking) via USB-C with PD, it might not take long for screens to follow.

Stepping 48V DC down to 12V, 5V, 3.3V is way easier and can actually work the way you have described above.

<progress> requires some vendor-specific prefixes last time I tried theming it using CSS (unless you're using "theme" to mean host system/window mananger/browser - wide theme). There is no common subset (that I am aware of) of CSS properties shared amongst browsers that can be leveraged to even decently change the <progress> element's appearance. So I'm not sure that it is the best example.

I agree that many of the list _are_ themable enough to warrant investing the effort to wrangle their particular interfaces over reinventing them entirely with <div>s.
Similar ceramic or crystalline superconductors took a long time to convert into useful cables. One technique is to fill a hollow silver(!) tube with powder, and then press it flat to compress the grains so that they touch. It may be possible to re-use similar techniques as-is, but that's hard to predict.

One theoretical paper suggests that the copper doping has two ways of occurring in the crystal structure, and that the more energetically favoured one is not the desired configuration. It may be very challenging to produce the desired crystal structure in bulk, and then it might not be stable over long time periods.

With most superconductors, they start to lose their benefits close to their critical temperature. So this material may not be able to support strong magnetic fields or high currents.

I expect thin-film applications to happen first. It's easy to control, easy to make large contiguous surfaces, and very useful for all sorts of things. Thin motherboards, LCD/OLED display panels, flat antennas, etc, etc...

100% my experience as well ! a Few times a year I try to move to Wayland on my modest old Asus laptop with NVIDIA 950M chip.

Either I spend the day with black screens and weird fixes that I had to google on my phone. Or if Nvidia is working there is at least two other things broken, which never seems like an easy fix. Zoom, tearing, dpi etc.

I'm sure you experience are different than mine, but currently these are the problems I have with Wayland and the not have with Xorg.

It's certainly not unreasonable to test software locally with HSTS (and other environmental configurations), sure. It just isn't good practice doing so on localhost, but instead in a jail or container with its own local network IP.

Do you also test your crons, secure integrations and terminal configurations directly on your local environment as well? That just seems tedious, arduous and/or pollutative.

Plenty of domestic applications still require higher voltage (well actually power but I presume you aren't suggesting 12V with high current). Vacuum cleaners, hair dryers, anything portable that produces heat. Building houses with low voltage sockets would be really frustrating for people living there.

Is the danger of 230V actually significant in this day and age? I wonder how many fires/injuries are caused by 230V that wouldn't happen at a low voltage.
