I (and many others more qualified) have run the numbers. It's not pretty.

A decade ago biofuels were my first thought. The maths simply don't add up. Our options are far less energy per person, far fewer people, other sources of energy, or, most likely, some combination of these.

The highest claimed yields are for algae, at a rather improbable 1,000 gal/(acre * year):

[Y]ou might consider floating the algae offshore, along the Pacific and Atlantic costs. It's roughly 1,300 miles from San Diego, CA to Port Angeles, WA, and 1,800 miles from Homestead, FL to Lubec, ME. Dividing our 443,000 square miles by those two added together, we find we'd have to extend our grow region some distance off-shore. That is, 143 miles off-shore. The full length of both coasts.

Or perhaps you'd prefer to re-purpose the Gulf of Mexico. Its total area is about 600,000 mi2, we'd need about 3/4 of it dedicated to algae growth.

Have moved around several places in the UK. Big cities, countryside, etc. The only place where I got the speed I paid for was a small town in the middle of nowhere (and I got 70Mbps, I don't use a lot of bandwidth and I would say it was still too slow...and the connection was down/slow constantly).

The take up is good - look at Virgin Media, literally the worst reputation in the world, it is difficult to build a customer service operation that bad, and they still get good coverage over their network. Equally, you have a ton of local fibre operations that have done very well (CityFibre as an example). Why have other countries done this? So many obvious problems (do you actually work for BT?). Also, the fibre offerings of larger companies are generally not competitive on price (have you thought about the incentives of this? BT's strategy was: run down infrastructure, buy rights to the Premier League...if they created a competitive fibre product, that would involve risk).

Also, no-one expected the current applications we have today. Like great, you are obviously clever but the point is that some things are unknowable...the future is generally one of them.

EDIT: you do work for BT...fml.

I don't like those tricks. The Netherlands has a 'inburgeringsexamen', which requires you to know all kinds of crap about our country and details about royalty which ordinary dutch people would not know and would not care for. Teach immigrating people practical things, local customs and ways in which the norms differ from elsewhere if you want them to feel at home faster, don't use them to act out your pet peeves and favorite anachronisms.
This is a very lame argument. Manufacturing capacity isn't some fixed constant of nature, it's whatever makes sense given the market for the product. So if there's a large market, a large manufacturing capacity will be created.

It'd definitely be an interesting turn of events to see Scottish Gaelic kept alive by immigrant communities that needed to learn it, and then just kept using it because other immigrants also spoke the language.
You don't seem to understand the word "flagship". It doesn't mean the most bodacious ship in the fleet. It means the one from which the admiral flies their flag. This is clearly Google and the Pixel, in the Android analogy.

People said that about electricity, too. A lot of people died. Houses burned. Norms were changed regarding cabling and earthing. Hopefully, whatever we decide to adopt as a technology will come with adequate safety norms.

While only tangentially related, a lot of people think about the Hindenburg accident when talking about either hydrogen or dirigibles. But those contain less fuel than an airplane, at least in terms of energy. And 35 people died, around a third. To contrast with airliner accidents. But it sure left a mark on collective psyche. And I agree that hydrogen is incredibly volatile and explosive, which isn't a good fit for every application.
What did the programmers commonly do that these females found revolting?

I've never lived in SF so maybe it's different there, but in my experience in the industry the "tech bro" thing is a complete myth. Most software engineers are just quiet nerds/geeks, mostly Asian + Indian, and are the absolute last thing from being "bros" (unless the word "bro" has been redefined and I never got the memo).
I would guess that because the Scottish accents are so distinct (to the point of being unintelligible to many English speakers unless the speaker is making an effort rather than just speaking in a relaxed manner) and well known, it provides a lot of the identity that the effort to preserve Scottish Gaelic needs to rely on. And Scottish accents don't seem to be weakening much.

Is "cancel culture" new? What happened in the past to people who would say inconvenient things (swear words or blasfemies in TV, being homosexual, ...)?

Bigotry was always there. It's just that nowadays we have a different cultural majority.

What's irritating about the present situation is that nominally the current cultural majority was against the bigots of the past and yet is applying pressure against who thinks differently and thus becoming bigot themselves (bigotry: "intolerance towards those who hold different opinions from oneself."). I'm sure people have opinions about whether the reasons to apply the corrective pressures are well founded or at least in good faith ( also have personal opinions about that) but that's not so important IMHO; people can be wrong: dogmas are dangerous; we should be able to have candid conversations about things.

That's said, I have the feeling that the critiques of "cancel culture" coming from the right are not based on the desire for an open dialogue but more a combination of whataboutism and playing victims to strengthen in-group bonds.

This is driving us apart even more. I want to know how do people who think differently than I do think.
Underground hydrogen storage is a demonstrated technology, not experimental. All that's required is scaling it up, and there's plenty of room to do that. The only real missing piece was sufficiently cheap electrolysers for use with intermittently available power, but that's coming along very fast now too, with rumors of costs as low as $200/kW in China (and a recent contract win of $350/kW from a European maker of alkaline electrolysis systems). This is more than adequate for hydrogen storage.
My main question was are the only examples in Mercury, and Gold?

AI, and Hg are next to each other on the periodic table, just on the metal / non-metal boundary, beneath them are the Rg, and Cn.

Rg Roentgenium has a short half life, but seems to be tricky to make, it is expected to show some Relativistic properties though:

https://en.m.wikipedia.org/wiki/Roentgenium

Cn Copernicum, according to Wikipedia seems to show RQM effects it acting like a noble gas, albeit one with a half-life of at most 28s:
https://en.m.wikipedia.org/wiki/Copernicium

If so why only these too? I’d expect there to be several others with mysterious properties too.
That’s the basic idea behind the IWW, but because of their tremendous success with that tactic early in the 20th century, laws were passed that made it illegal to strike in solidarity with workers in another workplace. It still happens, (for instance there was a lot of that kind of activity in the recent teachers strikes) but it is illegal. Ironically it’s basically illegal because it works.

I think that is indeed true on the individual level, but when a large percentage of people are on Twitter such that cancellations lead to actual real world circumstances, it in fact matters that people who are not you do in fact play because it might affect you.
Yeah, this feel like a comment that might have been OK at a cocktail party or made offhand in the middle of an essay on something else.

Although I agree with the sentiment here, you picked some pretty extreme examples. OF course a famous author and ex-president is going to have more respect than some anonymous corporate drone at Google. It'd be more weird if that wasn't the case.

> What’s the alternative if one is not to use Twitter? How do you publicize your findings or insights to a broad population?

If you can, you do it behind the shield of a faceless corporate entity (that you own) doing the promoting, rather than tying statements to your own personal identity. You don't stop using Twitter or Instagram et al., you stop using them to project your personal opinions out into the world. Your opinionated discussions are reserved to people you trust and to smaller in-person environments where you can have a real dialogue of understanding and exchange.

If you want to build value in your own identity, you take on the risks to chase the rewards. I'd suggest strictly talking about work, and never deviating from that. If you leave that lane, these days everyone knows the risks they're taking, it's blatantly obvious.

You publicize your findings, you don't spout off about such and such highly charged partisan social cultural revolution topic that is just begging to get you in trouble if you twitch the wrong way. I think that's really plainly obviously the way you handle it. What's so hard about that? Oh I just couldn't help throwing out my meaningless 2cents on BLM while discussing my work on using machine learning to recognize giraffes standing next to stop signs; I just had to get my opinion about black-white relations out there in the open, because what I have to say about BLM is super important and could change the world. No, just publicize the findings.
Yes. That's remarkable more sensible than futzing with naked hydrogen molecules, though the challenges here have been great as well.

That last sentence took an unexpected turn.
I think this might be too simple. In particular, the absence of a way for the client to specify a desired language or supported mime types, query strings as the only way for the client to send data (what about uploads? Or non-idempotentent requests like registration?),and the absence of compression all seem to go a little too far to me (compression could be done using a parameter to the mime type).

And really,why replace http? The complaint seems to be mostly with html, so why not just makr a gemini text format,build some browsers that use that as the default instead of html and specify semantics for how tls works, like custom status codes to request a client certificate and recommend TOFU certificate trust. And maybe specify certain headers that shouldn't be used, like cookie.

Cheers!

Air-crete is basically foam (like dish soap foam) mixed with concrete. It can't solve all of our physical problems but it's pretty useful: It's fire proof (you can build a furnace out of it), water proof (you can build a boat out of it), also bug- and mildew-proof. It's lightweight, strong, durable, and non-toxic. You can work it with hand tools. It holds nails and screws. It can be formed in blocks or panels or columns or poured into molds. The machinery to make it can be assembled from off-the-shelf parts for a couple of hundred dollars. You can use plain ol' concrete mix and dish soap for the foaming agent.

I heard about it years ago (Christopher Alexander wanted to use it with his Pattern Language generative architecture) but it seems that there's been a recent bloom of interest and applications with the invention of the small backyard-scale foamer/mixers. People can and are using aircrete to make all kinds of homes and other buildings. One group is teaching workshops on making cool spherical homes that cost a few thousand dollars, can be built by a handful of people in a couple of weeks, and will last for decades or even centuries.

This is just one example of a really keen solution that's (as yet) underutilized. I collect ideas the way stamp collectors collect stamps, and I've "seen things you people wouldn't believe." (I.e. ever heard of a phase conjugate mirror? You point your flash light at this mirror and the light is reflected back into the bulb.)

> For metal-air batteries, one of the more promising areas of research, the problem is actually worse: the cells gain mass as oxygen is reacted with the metal anode, discharging the battery.

That's interesting, thank you for the info. Having a different characteristic from the usual one might lead to interesting applications. For instance, airplanes use a lot of fuel for takeoff, as they pay double the price for the weight of their fuel: they need to carry it up, when they have the most. This could actually be a game-changer, I think.

That could also be exploited: raise the battery when it is charged, have it gain weight, generate electricity while lowering it. Perpetual motion doesn't exist, of course. But gaining a bit of extra mileage is theoretically possible here :)
Worth noting the Scots language is also a thing, separate from Scottish English and Gaelic.
E-Verify’s “SSN Lock” Is Nothing of the Sort
Since you mention analysis, I recommend Yet Another Introduction to Analysis and Metric Spaces by Victor Bryant. They should be at the right level and a lot of fun.

Another analysis suggestion is Creative Mathematics by H.S. Wall. It is a book that walks a high school level student through creating the proofs themselves. The topic covered is a stripped down version of analysis, calculus, and later even differential geometry. It's really brilliant. Going slow and having fun when you're a teen would be much more productive than going fast and burning out.

The Spivak book is a good suggestion and might be a little difficult depending on their actual background. The books by Gelfand mentioned by someone else (there's actually a series of them that cover algebra, functions, coordinates, trigonometry, etc.) would help provide the needed background.

The book Conceptual Mathematics is claimed to be aimed at high school students. Maybe give it a whirl and see what happens. If they know calculus, then Advanced Calculus: A Differential Forms Approach by Harold Edwards is a gem. The first three chapters should be readable, as they give heuristic discussions of the topic.

> I'm fairly certain if a judge haf given him his job back he would have accepted it.

From that doesn't follow that one should just say nothing (that isn't utterly benign and impersonal) on the web. This would leave something like participation in public debate to the forever unemployed or bots. If we think that far enough, you could also not communicate with other human beings in private messages, because they might take a screenshot or record it, and so on.

This could very well lead to a world where having a well paid job will come with less freedom, dignity and happiness than even being unemployed does today. I cannot affect the world much with my decisions, but by them I can unilaterally decide what kind of world I would have deserved to live in.
All small measurements in the US are done in power-of-two fractions of an inch. In fact, much of the initial opposition to the metric system here was led by the construction industry, who has found from experience that 1/2" 1/4" 1/8" 1/16" etc. measurements are too convenient to ever give up.

Thanks. My most recent one took quite a long time. I'm going to be distributing floppy disks with it soon as a fundraiser

I'm curious though: Would people be interested in tossing $5 or $10 my way for a custom labeled vintage 3.5 floppy, with my software on it, made to look like the early 90s, shipped to them? It's more of a novelty artpiece, I realize it, but I have a box of old floppies, a couple drives, a bunch of packaging material, and a color laser printer, I can put them to work (the floppies will be from this viral image I made about 9 years ago, went viral on its own, don't ask me about the secrets, I do not know them: https://img.buzzfeed.com/buzzfeed-static/static/enhanced/web...) I probably have the original somewhere, probably on that same drive with those couple hundred bitcoins I tossed.

Anyway, I'm about to make maybe 10 of these floppies as a test run (and I'll put some surprises on the disk as well) but if nobody wants to toss the cash my way then I probably shouldn't bother.

I'll have to buy the labels, get glabel to have the right parameters, carefully affix the labels and test the disks, make the "marketing" material ... it's not a zero cost or low time operation.

This is silly, I should just do it. Who cares if I don't sell them ... my highest profit aspirations here are like < $500 ... it's silly worthless pocket change, I'm just looking for excuses to be lazy. Ok, I'm stating it publicly, I'll do it.
