> I see oxygen production being such a basic industrial process, that I never could've imagined even a most poorly industrialised country having troubles producing it.

This article discusses some of the challenges being faced, sounds like most of them are around distribution. India has a large steel industry which is very capable of generating and condensing oxygen.

Is there a link anywhere to the actual study this post references?

I was surprised to read that there were over 100 cities in the U.S. offering municipal broadband as of 3 years ago and even more surprised to read there now would be 560 cities offering municipal broadband. I know there are at least 18 states that restrict cities from creating municipal broadband networks[1]. Does anyone know if there's a comprehensive list of municipal broadband offerings? This lists a lot of municipal broadband providers but it's nowhere near even the 100 quotes from 3 years ago:

AMM's are a category of decentralized, non-custodial exchanges that are also autonomous. Basically this means there is no incorporated or any financial intermediary needed to set them up, and no gatekeeper needed to set them up, and no custodian of funds that are used to trade on them.

In this type of exchange system, order books and market makers are replaced by liquidity pools, where individuals put up two assets (for example a liquid asset like Ethereum and a less liquid asset that they wish to have liquidity in). This process automatically spawns a smart contract from a smart contract factory, which has all the functions for maintaining that liquidity pool in perpetuity. The smart contract has no administrator and it allows other market participants to trade in that asset. The additional beauty is that the other market participants do not even need "Ethereum" the liquid side of the trading pair in order to buy the asset, as the smart contract factory will route whichever asset the trader owners between liquidity pools. For example, if they had Tether, the smart contract factory will find the Tether/Ethereum liquidity pool, and the Ethereum/NewToken liquidity pool and exchange it at the best price.

Also anybody else can add extra liquidity to the liquidity pool.

All liquidity pool providers earn trading fees from people that buy and sell. Turning them all into market makers.

The final point is that the market decided that these trading fees are not a good enough incentive to add liquidity to liquidity pools, so it is important to know that all liquidity pool providers actually receive a bearer token representing their share of the liquidity pool. Third parties have created additional financial products that allow depositing this bearer share and earning other assets for doing so. So people that want to passively earn have to provide liquidity and lock up that liquidity for some time, and it is working extremely well.
I suspect that this represents a practical consolidation of power by leadership in tech. While you can't come out and say "hey, we want to corner the market in white male nerds", you can say things like "Mean people suck, why can't we all just get along, no politics on slack, we're good right?"

Think of it as the tech-liberal backlash. Tech has been wrestling with representation and diversity for a while now, indeed more visibly than many industries, and some limited progress has been made, maybe not as much in raw numbers than in qualitative stuff like less-hostile workplaces. But it is far from the _worst_ industry for diversity.

Meanwhile, it gets harder and harder to hire engineers, and the dominant class isn't going away anytime soon. If you can figure out how to signal to them that "hey, Basecamp/Coinbase/MyCo is a place you can just be you and chat about games and gear without worrisome questions about equal pay" then you potentially achieve a short-term recruiting advantage.

I say "short-term" because of course, it's short-sighted. But worse, it's cynical, as it wants to halt the minimal progress that has been made behind a smokescreen of civility and fairness. And given that it's being openly pushed by white male leadership, it's fully reactionary, and white-male supremacist. It's a harsh term to use but we haven't really uncovered a more accurate one.

I’d like to see:

1) Genre channels. Each channel is a stream of trailers with information about the film too, so you can quickly figure out if you like or don’t like it, without having to scroll around

2) Consider adding a reviews channel for each genre too, talk me through some of these shows

No. If they don't find an excuse plausible (possibly due to the objections of the counterparty), they might order production of evidence to support it.

A judge could in theory respond with 'orly, hand over source code'. What the judge could not do is say 'ok, source code shows you're telling the truth, but you should change it to record the information the prosecutor wants.' Only the legislative branch could do that.

Not completely unrelated: FB makes killer programming tools loved by most.

- PyTorch for Deep Learning overtook TensorFlow in Academia and Competitions and breathing down the neck in Industry despite the latter having significant inertia.

- React.js is THE hottest frontend framework now.

- GraphQL is highly adopted in the industry.

I want FB to exist as long as possible and very successfully as I do not want the tools to go away. I have worked with two of the three, and I love them. It had made me fond of and loyal to FB and FAIR.
Once you see coppicing it's one of those things you'll notice everywhere that was cultivated for a long period of time. I'm surprised at how straight the shoots would grow, and farmers were pretty good at managing and multiplying timber using this method.

Another proto based RPC framework with code generators mainly for Go that also explicitly says it's simpler than gRPC is Twirp from Twitch: https://github.com/twitchtv/twirp

“With your new KEK, we just re-encrypt your DEK”

⇒ when users change their password, you have access to the DEK (you decrypt it and then encrypt it with the new KEK)

“one to encrypt your data (the 'data encryption key' or DEK)”

⇒ when users change their password, you could decrypt their data.

I think this boils down to “you don’t store user passwords, but when users change their password, they must trust you to not look at your data or store the KEK”.

Where’s my error?
Your experience mirrors mine to a letter - I appreciate the wide variety of use cases that are covered by Webpack (a number of which are crucial to our build process), but its performance is abysmal (20m+ on CI) and totally inscrutable; making the potential switch from it rather enticing.

Especially as seeing that there is no good solution (but a lot of attempts at them), I feel it somewhat points to this overcomplexity being a problem central to Webpack.

How does one learn to analyze these quarterly results and other financial reports (e.g., 10-K)? What books/videos/courses would take an absolute beginner towards becoming an expert? Would proper analysis of these results/other financial reports enable one to decide which company is a worthwhile investment? It seems like learning accounting would be a good start.
I enjoy my Fuji X system camera and the colours it produces. Sometimes, however, I'd like to do some RAW processing in Linux (Darktable) - but of course this means that I lose in-camera film simulation.

Since the camera can store the same photo in 2 different formats (RAW+JPEG), I'm wondering if it would be worthwhile to use a lot of these file pairs to try to get a LUT allowing to map Fuji RAW files to Fuji-Like JPEG results.

Is there anybody knowledgeable here to tell me whether this approach is doomed from the start or if it could be promising?

> I'm sure everyone would agree that people have eyes and phones and that a phone can take pictures. Why is that a fact claim? Just show the pictures.

Every single one of those questions is establishing a fact in the record without which the opposing counsel would potentially have grounds to object to the presentation of the pictures. You can’t just show pictures without an explanation through facts themselves introduced as evidence, whether by testimony or otherwise, unless freely stipulated by the opposing party, of what the evidence is, where it came from, and why it is relevant.

Again, yeah, it makes crappy theater. The rules are about due process for the parties in a case, not keeping the proceedings engaging for an audience.
LO2 reserve in any hospital should've been enough for weeks per refill.

And hospital with on-site O2 generation should've never had any issue. Any industrial scale O2 production machinery would've had many times the capacity reserve.

But they didn't. Double digit of hospital O2 generators were out of service, and LO2 tanks were never filled to full because hospitals were saving on LO2 service.

Some hospitals with central O2 systems from either tanks, or generators simply had them disabled for unfathomable reasons, had them broken down years ago without any attempt at repair, or simply never ever used them, so they don't know how to operate them.

That made me naïvely curious about 'Aladdin'; yep: https://en.m.wiktionary.org/wiki/%D8%B9%D9%84%D8%A7%D8%A1_%D...

Seems unrelated to Hindi (via Sanskrit) दिन 'din' meaning 'day' though. (Not that I expected it because 'day' and 'religious' are similar in meaning, just curious because there is overlap, and borrowed terms (well, with Persian, but those in turn often derived or cognate with Arabic, at least in my idly curious Wiktionaring experience anyway).)
The book “Sapiens” does a great job of exploring how culture enabled us to evolve apart from changes to our DNA. I couldn’t agree more.

On instincts: the neocortex is built on top of all the other more instinctual parts of the brain (vision, movement, etc). But this may just be an artifact of being embodied. Is there much difference between a RL agent that gets its data by processing pixels or directly from a simulator? I wouldn’t say there is, except that these non-pixel-parsing agents would have a hard time doing anything outside a simulator that was doing the processing for them.
Please forgive yet another nitpick since this thread is kinda negative, but “System 8” is probably what Copland would have been named had it been released. The OS we got was “Mac OS 8”, and in fact the name had already changed with Mac OS 7.6. Supposedly this was one of the things used to kill off the Mac clone program since the cloners licensed “System 7” but not “Mac OS”, but I don’t know how true that actually is.
Well, at least now I am aware of that this is not an official standard and most people think that it is more harmful than helpful.

This post and the related issue should be spead widely under the go community, so that at least everyone is aware of that.

Thank you for sharing.
Command is (mostly) control under Window (CMD+C/V/X for copy/paste/cut, CMD+P for printing, CMD+Z for undo, and so on). It's also used for alt-tab.

Option is Alt. Used to modify some keyboard shortcuts like the above, sometimes on its own, and often used to type in alternate characters than standard on your keyboard (Option+e e gives you an accented e).

Control is honestly something I use often outside the terminal on macOS. I think Control+<left/right arrow key> gets you linear navigation with multiple full screen windows or multiple desktops. It probably does more, I don't know.
A counter point would be to look at the Python ecosystem. They have many fewer libraries but the ones they have are very well maintained and widely adopted.

JS/Node is full of unmaintained projects that people inevitably need to migrate away from.

Of all the new choices in bundlers today, it’s also inevitable that some won’t work out, yet they will drive hype and adoption, which could have been spent on already established tools such as webpack.

Yes, innovation is good and no one should tell someone what to do in their free time.

But it’s always going to be harder to build on top of old rather than to write something new, but what is new eventually becomes old...and the cycle repeats.

I’m a creative pro who works on math software, so, synergy. I just feel like I am slogging through mud to work with versions of mockups, quickly bouncing stuff to git or onto our damned fileserver, all that administrative jazz.

(I will note my college illustration professor loves her iPad Pro with a passion that would fill an Apple keynote—she ditched her Wacom instantly.)

But though I’m iffy on the Pro in iPad, I am pro iPad, if only because my somewhat elderly parents love the thing. They are like some Platonic ideal of iPad users—they have totally and completely ditched their Mac, and do all their banking and medical records and weather (old people love weather) on their iPad, with a fluency they never, ever came close to achieving with a mouse.
Therefore, trees are fat.

> I'm most sad that so many smart humans are working on this of all the important problems in the world.

Depends upon values and perspectives of the problem. Part of me agrees with you, and yet part of me is sympathetic to the goals of connecting the world, encouraging community discussion, and bringing transparency to social issues and reducing the power of governments to control the narratives. - to the point that many governments fear FB and ban it outright. (e.g. Do you think China banned Facebook because of "misinformation?" Or that the ratio of real information to misinformation was a little too much for them to lose control of their propaganda narratives?)

Would I say that's more important than sustainable farming / agricultural tech? I don't think so - but to each their own.

https://en.wikipedia.org/wiki/Pollarding is another similar technique, probably most similar to this one.

It's an interesting one to discuss with arborists. In North America, there isn't a long history of pollarded trees, so the technique is generally frowned upon since it's essentially "topping", a universally derided pruning method.

European arborists who maintain historical trees are more familiar with pollarding, and commonly are asked to explain why they believe their continuance of topping is defensible as a modern or scientific technique in the care of trees.
One number is 'too many'?
I have many iMessage groups, but it is an almost unspoken rule that you do NOT add a green bubble user to the group.

It downgrades to standard MMS which doesn't have all of the features, AND delivery is hit or miss.

With iMessage I can be fairly sure that all messages will arrive, with MMS groups... it's a shit show. There's been plenty of times where someone whose a green bubble will receive only part of the group messages, or none of them whereas the rest of us do. It all depends on the carrier.

Apple Music has New Music Mixes and Continuous Playing.
Cost of iMessage is built into the price of the iPhone and other apple products. Why would they pay to develop and maintain it for other devices? Apple doesn’t monetize their data like other messaging services/social networks. If apple charged $3/m for iMessage on Android would you pay it?
I love my 12 Mini and I’m really sad about the mediocre sales. I hope Apple keeps the product around for us nerds who love small phones. They’ve done the work to design the thing and build out the tooling for it so they might as well keep making them as long as they keep selling, even if it’s not their most popular version.

Electric - burned down several towns in California 2 years back due to failure to maintain the lines over the last 30 years.

Gas and Sewage rarely require infrastructure upgrades... ie. there's no new home appliance that requires "more" gas than the lines can currently provide (or provided 30 years ago).

Water? What about all the lead in the water issues that were exposed a few years back? Do you think they would have just fixed that if nobody made a big stink about it?

ARPAnet has literally nothing to do with how commercial (or municipal) ISP's operate today... not sure what point you're trying to make.

FAA has been attempting to upgrade ATC services nation-wide for years and years... still hasn't happened. Plus they've outsourced certifications of new aircraft to the manufacturer (because they don't have the staff to do it themselves, because they don't pay as well as private companies) which led to the Boeing 737-MAX thing...

CDC is now a political organization spouting whatever the current president wants (at least under Trump and Biden)

FDA - shills for the beef and corn industries...

None of your examples are good.
I wonder how many FB users are like me: people who don't identify as FB users bur who do actually use FB out of necessity, and pretty often.

I've moved several times in the last year, and (unfortunately) FB is how I:

- connect with local groups of parents (FB has no competition in this vertical)

- connect with local athletic groups (Strava and others exist, but try planning an outing on Strava)

- see what the local take-out restaurants are offering today (FB and Instagram own this niche, which has exploded)

- get recommendations on contractors, service providers, etc (often passively, by searching groups for recent answers to someone else asking the same question)

- find out about when local organizations or companies I care about are doing something (you can't really rely on libraries etc. announcing things via email anymore, but they won't do anything without posting to FB)

On top of all this, I use Instagram, not only to post photos but also to explore the area around where we've settled. I search by location a ton and have found it's a great way to learn about what people do and where they go when you're not able to meet people and get recommendations the normal way.

So yeah, I rage quit previously but FB has got my number again.
I'm not sure what you mean. Assuming that everyone knows all of their own debts and credits, then they already know their net balance. In the riddle, everyone already knows their net balance is 0, so I would question why everyone is so pessimistic about the future unless the terms of their debts are less favorable than the terms of the credit they've given out.

That appears to be a product of merging iPad technology with the Mac ecosystem. The display is basically a giant iPad Pro, isn’t it? They borrowed some thin from one product and applied it to another. The M1 allows it, they just needed to add a larger screen, remove some sensors, and flash a different OS.

Obviously dramatic over simplification but it doesn’t seem to be the usual kind of thin for the sake of thin design - this iMac seems objectively better than its predecessors and its thickness (or lack thereof) doesn’t seem like a problem or unnecessary constraint.
Well, counterfactuals are tricky. In the fish example, if you compare to nobody selling fish at all, they are adding value by creating a market where there wasn't any before, even if it's in a monopolistic way. But if your alternative is a competitive fish market, maybe no value is added, but the monopoly is charging more for it.

Charging more is capturing consumer surplus value. If it weren't still worth the money, they wouldn't pay for the fish. The higher price more accurately reflects that value of the product to the people who still buy it. (Assuming they know what they're doing.)

Whether or not charging more is good or not depends on your point of view. Buyers and sellers have different opinions. I believe "charge more" is a slogan generally repeated approvingly around here when we're talking about developer salaries?

Here's an example of capturing consumer value that's considered relatively benign, good even: you can listen to a lot of music for free these days, but then Patreon came along and convinced a lot of people that artists should be paid more. The market price in a perfectly competitive market is that music should be free, but sometimes the fans themselves disagree with that.

It doesn't seem like there is any objective truth to the matter as to how much music is worth. There are only opinions. Sometimes you can do some math, but the input is opinions, so the output is aggregate opinions.

The same seems true of other prices. Costs usually set a floor. Consumer value is higher than that, but people disagree on what's "worth it."
