Lots of great discussion around supply vs. demand.

As an Elixir dev, I will add that it being a niche language is also beneficial from a cultural standpoint. I want to work at a place where devs are encouraged to tinker and explore cutting-edge technologies. Not to mention a generally more forward-thinking culture, at least on the dev side.

“Established” technologies like Java make me think traditional, top-down, “butts-in-seats” kinds of companies. Of course, this can’t be generalized, but I think there is at least some correlation. Besides, using enterprise Java is, at least for me, soul-crushing in and of itself.
That's "for a hole you can barely crawl through". The 10-m "stage 3" tunnel would consume 1.38 gigawatts per day per km, or 57,500 kwh per meter. By contrast, the energy consumption of a traditional Tunnel Boring Machine (TBM) is about 356 kWh per meter [0], or 0.62% of the plasma boring robot. Let's get this in perspective, the Palo Verde nuclear power plant in Arizona is the largest in the US with three reactors and a total capacity of just under 4 GW. Certainly not what I would characterize as "super-cheap tunnel tech".

> The cost for offshore wind projects has fallen so fast in the UK that the many of the latest projects don't need subsidies

I'll have to check that. Sensational news usually omit quite a few important details.

> I'm pretty sceptical about the phrase 'base load', when it comes up, such as in a HN discussion[2] from a last week, it seems to be used to describe wanting to choose slow and/or expensive power plants.

No. It means that wind and solar literally produce zero output when there's no wind or there's no sun.

However, life goes on: trains run, homes are being heated, businesses operate, factories produce goods. This is base load.

So, to cover a wind farm or a solar farm that produces inadequate power you need to get that power from somewhere.

Where from?

And this is the question that renewables enthusiasts just brush off as not important.

"We can store energy". No. We can't. Not in the amounts required.

"We just build more". How much more? Does this "more" remain cheap then? Yea, you can transmit it from afar, but it's no mean task in itself. And not cheap either.

But sure. "It's all about keeping slow power plants". What the hell does "slow" even mean in this context, when we're talking about wind/solar which can't even be properly used in load following precisely because they are extremely slow.
That is a very overblown assumption of what an extrovert is assuming that extroverts can't focus because they're busy socialising.

I know plenty of supposed introverts that cannot focus.

Being an introvert doesn't necessarily mean you aren't necessarily social or sociable.
> Do you work in a team, or do you like to work solo

This question doesn't make any sense. Work is very overarching term here. There are may aspects of "work", some of them require you to do "thinking" (which is a solo activity) and some of them require you to communicate and discuss the outcome of your thinking (which is a team activity).
I hear some of IBM's stuff has a pretty long history to it.
> from the perspective of recruiting in Australia.

Even accounting for that line from the comment?
Completely agree that it's on management to foster a great place to work. I put scare quotes around 'labor' and 'management' because they're really nonsense terms.

I'm a big believer of culture coming from the ground up; you can't design it, you can only help it grow with good soil, water, and food.

> Should we change the law so that people can sue software makers who failed to make their software accessible?

With appropriate dispensations for non-commercial, entertainment, contracted production, and small businesses, I think it would be a good thing. I'm not sure that having all those holes wouldn't make such a law meaningless though. I'm also not sure that the largest and wealthiest companies wouldn't lobby to get legislation raising the barrier to entry and making the software ecosystem that much worse than it already is. Brain-computer interfaces and other advances (eye/motion tracking, non-invasive brain/nerve/muscle-monitoring sensors, voice input, etc) might make all this inconsequential if they end up coming to fruition, too.

Speed of change is not an argument for the administrative state. If anything, it's an argument against.

Laws delegating powers to executive agencies are done all the time, some successfully, some not. I've never heard anyone say that the FAA is overstepping its statutory authority, for example. Nor the PTO. Congress might disagree with what they're doing, but that's different than saying "they have no business regulating that."

Lastly, it's not about what branch you trust more. Judges were at least appointed by someone who was elected, not hired by a Civil Servant.

It's important to be aware that one isn't either an introvert or extravert; it's a scale. And you can move around it.

I use software everyday built by (large) teams which no doubt required some extroverts to get done. In fact, I don't think I use any software written by a single person?

Some people must not have worked in very good teams when I see the subject come up. Having my first proper training (it involved Belbin, but there are other models like it) openee my eyes to understanding interpersonal dynamics and what separates funtioning dynamics to non functioning ones (some diversity in attitudes and skills!). Writing great code means nothing if nobody knows about it, is able to use it, or needs it, etc. I recently organized a training like this for my current team (of highly skeptical software engineers) and it was a great succes.

It would be a good start if people wouldn't reduce themselves to a single stereotype. People can be and are multiple things at once, and I'd say it's extremely healthy and useful to be skilled in more than a single way.
Is it though? I find that almost every American I know closes the blinds - the exact opposite of what you're describing.
Honestly curious, what do you see as a solution to the heat problems reactors are experiencing? There was discussion about the combination of lack of sufficiently cool water and droughts in the new heatwave cycles.
My understanding is that with .NET Core, the experience of developing and running on Linux is on-par with Windows(?). However, my impression is that once it comes to building web services, ASP.NET has more "windows-specific" assumptions/moving parts - can someone knowledgeable on this correct me if I'm wrong?
Mimicking sunlight means providing all the wavelengths, including the harmful ones like UV. Some people may not be aware that e.g. lights[1] prescribed for Seasonal Affective Disorder can actually cause burns if used for too long. They are supposed to be used for short periods only.

The FDA does not regulate light boxes, so caveat emptor.

I disagree, Silo is not a term invented to slander people its a broad term where two teams don't work or communicate with one another like they should.
Since batteries are always the issue... How inefficient is mechanical storage? For example using electricity to just raise a heavy mass then as that lowers it can produce power. It seems that would be cheap to build at scale with the chance for almost unlimited storage.

I have to assume there would be a more than 50% loss through the process, hope someone on hn can comment. Maybe it's not worth it when you can tap into unlimited sunlight the next day.

One thing to note is that the most important benefits of sunlight actually come from (moderate) UV exposure, which is blocked by glass and not output by LCDs as far as I know.

My own personal theory is that there is a health epidemic related to lack of sunlight exposure from most people being indoors. And so in my fantasy future cities that I build in my head, there are ways that actual natural light is delivered without being blocked by windows, such as carefully monitored full spectrum and/or UV lighting.

Another related issue is the concept of a virtual window that you can see out of. I think this will also be a future trend, since windows increase heating requirements and again don't provide the key UV component of light. Also, for the majority of history, inexpensive cameras and displays did not exist.

So what I suggest is virtual windows that are thin OLEDs and follow the person to give them a different virtualized view of outside. Or using some light field or multiview technology. Along with full spectrum lighting. And not entirely related but I think it would be best in most areas to standardize on airtight construction, mechanical ventilation and energy/heat recovery ventilators.
In aircraft or maritime it's a system you can activate and stop paying attention to the controls or do a task like navigation, eating, or going to the bathroom for timescales on the order of seconds to minutes.

Tesla's 'autopilot' system is cruise control but with more mental overhead when the human needs to react because the human is being hypnotised by lack of stimulus and has to keep a mental model of what the car is planning in their head.

And 'full self driving' is an automated way of making the driver as unprepared for novel stimulus as possible. "You have to sit here and do nothing, but react in milliseconds when I fuck up" is not a task a human can do.

Tesla know this and have known this since before they made the features available and gave them misleading names. So when the human inevitably doesn't react in time in a scenario where it is impossible for them to react in time, they are the ones responsible.

Never called you a racist. Not even sure where you are getting that from either. You simply misunderstood what I said -- based on your own preconceived notions.

When I tried to explain (several times), instead of taking a step back and trying to understand -- you doubled down on your own misunderstanding and accused me of seeing racist undertones everywhere.

Again, I can only assume English isn't your native language, hence the confusion.
Weird you would re-surface that quote in response to that, since I don't think a reasonable person would interpret it as a criticism of younger generations, but of the changing times we now live in.

No one ever starts at a public library to study a particular topic, you almost always go to an internet resource first [usually Google]. And TikTok/the internet generally, has hijacked attention spans, but not just of children, but of adults as well.
The thing is that UV is harmful if overexposed but also harmful when there isn't exposure. Humans require a certain amount of UV to be healthy.

So I think what is needed is actually carefully dosing with full spectrum.
Heat is not light, that is not exactly what you said. Sorry. You didn't even mention light.

Physically as well as "mechanically", I suppose, they are very different things. Heat cannot travel at the speed of light, light can. Light can impart heat, but it is a partical-wave with various properties, heat is a general statistical statement about a set of particalls. They are not the same thing at all.

Now, as for how a sunburn works, it's not about heat. The reason you wear sunblock even on a temperate day (cold, even) but with lots of sun, is because UV light, not heat, burns your skin.

So, yeah, actually, this is different from a pure thermobaric explosive, if you want to get technical.

Now I understand you want to argue about whether "melting flesh" is unique to nuclear bombs - I never said it was. The output of a nuclear weapon, or reactor, is pretty darn unique, compared to a traditional heat thermal heat source. I don't think I ever even implied that there was some magical property of nuclear weapons which makes them "melt flesh".

You claim to be anti-nuclear yourself but you seem more interested in classifying the possible things which could be flesh melting, and/or you seem to have little to no knowledge of actual physics, thus I have extreme trouble taking you at your word.
I have contacted McDonalds Australia (I am an Australian) and asked them for comment.
Here's a very rough breakdown of the operations it does:

1.33 s 56.7% specialized Collection<>.split(separator:maxSplits:omittingEmptySubsequences:)
263.00 ms 11.2% Substring.lowercased()
226.00 ms 9.6% specialized Dictionary.subscript.modify
189.00 ms 8.0% readLine(strippingNewline:)

As you can see, calling split on the string is really slow. The reason it is slow is that it's using the generic implementation from Collection, rather than String, which doesn't really know anything about how String works. So to do the split it's doing a linear march down the string calling formIndex(after:), then subscripting to see if there's a space character there using Unicode-aware string comparison on that one Character.

Swift is really nice that it gives you "default" implementations of things for free if you conform to the right things in the protocol hierarchy. But, and this is kind of unfortunately a common bottleneck, if you "know" more you should really specialize the implementation to use a more optimized path that can use all the context that is available. For example, in this case a "split" implementation should really do its own substring matching and splitting rather than having Collection call it through its slow sequential indexing API. Probably something for the stdlib to look at, I guess.

The rest of the things are also not too unfamiliar but I'll go over them one by one; lowercased() is slow because it creates a new Substring and then a new String, plus Unicode stuff. Dictionary accesses are slow because Swift uses a secure but not very performant hash function. readLine is slow because the lines are short and the call to getline is not particularly optimized on macOS, reallocs and locks internally, then the result is used to create a new String with the newline sliced off.
Apparently part of the problem with convincing skylights is that the light has to be parallel to be believed.

That’s tough to do without either reabsorbing a lot of the light you created, or creating a large box to contain the light source.

One of the interesting DIY designs I’ve seen uses a surplus satellite dish, silvered, with an LED array at the focal point. The reflected light of the mirror is mostly parallel, but your light source is now 20+ inches deep.

I spent some time instead thinking about indirect light, like an artificial clerestory. Never did build anything though. When I moved I had plenty of natural light so I stopped trying.
Also if you wanted to make really small fission bombs—like hand grenade sized—I would guess this is how you’d go around doing it.

How many coal plants are scheduled for construction, this decade?

The only place I have heard of plans to build literally any coal plants at all is in China, but they have not broken ground on them. China also says it will build hundreds of nukes, but has started only a few. It is building out solar and wind farms like nobody's business. China is always happy to cancel plans for what they turn out not to need. They even abandon things they spent big money on that turn out redundant: lately, a record-setting bridge you can read about.

We read about coal plants being shut down and scrapped, everywhere. The only place where coal plants are brought back online is in Europe in response to a regional crisis involving a war. Are you sure you want to stake claims about long-term policy based on emergency response to a war? That seems like a very courageous position to take.

>Is there no trade off where you flip the cube around to optimise for miniminimum inspection and solving time and totally forgo the inspection?

There is not an interesting trade off. You just look to see if there's an obvious good start. Even with 15s of inspection you are usually only planning like 10% of the solve. The majority of the solve is already figured out on the fly.

>On the second point, it seems like there is more room to push the skill ceiling.

Yes, being able to accurately and quickly track pieces under time pressure is a skill.

It is interesting that the amide form of nicotine is so essential for humans.

”In 1942, when flour enrichment with nicotinic acid began, a headline in the popular press said "Tobacco in Your Bread." In response, the Council on Foods and Nutrition of the American Medical Association approved of the Food and Nutrition Board's new names niacin and niacin amide for use primarily by non-scientists. It was thought appropriate to choose a name to dissociate nicotinic acid from nicotine, to avoid the perception that vitamins or niacin-rich food contains nicotine, or that cigarettes contain vitamins. The resulting name niacin was derived from nicotinic acid + vitamin.”
