Until recently, there wasn’t much demand for lithium. That’s the main reason for limited mining, in my opinion.

The cost of lithium was 9% of the cost of a lithium ion battery cell according to one analyst last year. Battery packs cost more than just the sum of the cells.

If lithium rises in price, it will affect battery prices, but a 10x increase would “only” double the cost of the battery cells, and the packs would be slightly less affected than that.

Realistically, there should be plenty of lithium for less than that, but it takes time to ramp, and lithium mining does not have to be destructive. The mining can be as simple as evaporation ponds in the desert[0]. (You’ll need refining either way.)

One way to think about this is that the maximum power of a Tesla Supercharger is 250 kW. So with one such SMR you can supply the electricity to power 200 EVs at the maximum possible power.

Also notice that 50 MW is only the approved level. Each module can actually produce more, but NRC only approved 50 MW so far. Towards the end of the article you can see that NuScale is applying for uprating the modules to 77 MW, and it's expected the NRC will review this in 2024.

Tech vs. Enterprise in a Recessionary Environment
European labor unions generally have industrial density now because many European countries' labor laws encourage bargaining at the sectoral level. U.S. labor law is not sectoral in orientation.

Be careful not to confuse cause and effect. Labor and social democratic parties were able to pass sectoral bargaining laws because unions had already achieved organizing density in strategic sectors, and business interests preferred to channel unrest into the courts and labor boards.
Yeah I don't think anybody would ever get on your case about tight turns that were possible. The problem only occurs when you book flights with segments that directly conflict with each other. Or depart within minutes of each other despite their origins being thousands of miles apart.

I agree and appreciate that AI is very fallible. That’s exactly why I think the algos should take direct user feedback to knock it off with certain content types seriously instead of very apparently ignoring it altogether.
> My experience in this world of embedded chips, is that many of the tutorials you read do not deal with power consumption really. They assume that you're playing with a dev board. Or that your application has copious amounts of power. But if you live in a battery powered world, your entire game lies around navigating between sleep and wake states on the chip.

This has been my experience so far trying to build my own devices at home. They all assume I’ll connect things to a USB port or have a power adapter. Material on how to deal with battery voltage dropping over time, determining battery level, etc. is really scattered. Makes me wish I was an EE major instead of CS.

The wonder of the true dark sky is that the numbers of perceived stars multiply significantly, giving an almost three dimensional impression.

That indescribable feeling disappears with light pollution. It can be a street light nearby or an industrial estate hundreds of kilometers away.

Nowadays one needs to go into extremes to experience such conditions.
There is a process called spontaneous parametric downconversion (SPDC), where if you shine laser of frequency f at a crystal, it will with small probability p emit two photons of frequency f/2 (energy conservation in play here).

If done correctly, the outgoing laser light and the two photons all travel in different directions and so can be separated and further directed using mirrors or optical fiber cables.

Because the process is non-deterministic, what we usually do is direct one of the photon beams towards a "heralding" [1] detector, while the other is directed towards the optical setup where we need a single photon [2]. If at a given moment a photon pair is produced, then the heralding detector will click; which tells us that is also a photon currently in our optical setup.

Finally, there is a ~p^2 probability that two photon-pairs will be produced at the same time by this process (and p^3 etc). To eliminate this possibility, in this experiment their heralding detector can detect how many photons landed on it any given moment. So if they see 2 or more photons in their heralding detector, then they discard this run, because now there are multiple photons heading towards the human eye.

[1] Herald as in the guy who announced that the King was approaching.

[2] In this case, towards the human eye.
Seems like a self-inflicted problem.
I don't know what it even means for this to "scale". I think people right now are hung up on Mastodon-the-social-network, the way it's been principally used until fairly recently, where people share servers and servers have a discernible culture, moderation, rules, community, that kind of thing. I don't think that's going to last long at all.

The Mastodon that stands a very good chance of killing Twitter is Mastodon-the-software; "ActivityPub", if we have to call it that. This Mastodon isn't a coherent social network at all; it's a successor to RSS. People run their own servers; "scaling" them means the same thing as scaling a blog would. Of course, most people don't want to run their own servers, but that isn't going to matter by the end of the year, when 10 different providers will boot up a "Mastodon instance" for you with a single button push. Nobody is going to be thinking about instances at all; they'll just have an address, the same way they do for email.

In this world, "Mastodon" is sort of a combination of most of the good features of Twitter, Blogger, and Google Reader, all at once. Users are as "discoverable" as blogs were --- meaning: very discoverable.

The baker is exploiting his customers' need/want for bread. The customers are exploiting the baker's need/want for money.

Another way to describe business is that all business is about ripping someone off without pissing them off (and ideally making them happy). Middlemen who make their profit off margins are the most obvious example, but as I said this applies to all forms of business.

I reiterate: All business is about exploiting someone somewhere for your benefit, no exceptions.
The exterior light I park next to at my apartment went out- I thought it wasn’t a big deal.

Perhaps something like: personal blog where you try to make X small apps per year. Or personal project where you write something on your own. Perhaps getting some certificate, everyone knows they arent very useful, so maybe get a cheap one (scrum.org?).

So if you have a candidate, who was a baker for their whole life, but in last year: started a blog where they do some coding projec(s), say "implementing tetris in language X" and then making weekly updates to that pet project, like adding score, adding AI. At the same time that candidate got some certificate in last year (everyone knows most of those certs are a scam).

To be honest when you are a junior, probably the hardest step is to get that first job; perhaps you can go to some meetups and plainly say there that you are a junior and search for a job.
Which is funny b/c I remember around 2008-2010ish, my 'has every game console but might play a PC game once in a while' friend went on a tirade about how Expansion packs for PC games were the reason DLC was so prevalent. [1]

My response was that the Tie Fighter Expansion he was referenced was 20$, had -hours- of content (On top of extra replay value for existing missions) and while not 'half' of the game, was a far better value than DLC of that time. (Looking at you, AC2 extra missions)

[1] - My date/timing might be off, but to frame, this was when.. -some- game (Might have been a Resident Evil 5 versus mode) had DLC that was primarily on disc based on the size of the download.

I think modern 'Mission Packs' tend to be cash grabs, at least in the sense of they usually are a lot lower value than the core game.
>> I have to believe it most likely stems from a lack of basic understanding and competence on the authors part.

That is unlikely, given that one of the authors is Timint Gebru. I'm quoting below select passages from her wikipedia page indicating her background:

In 2001, Gebru was accepted at Stanford University.[2][5] There she earned her Bachelor of Science and Master of Science degrees in electrical engineering[8] and her PhD in computer vision[9] in 2017.[10] Gebru was advised during her PhD program by Fei-Fei Li.[10]

Gebru presented her doctoral research at the 2017 LDV Capital Vision Summit competition, where computer vision scientists present their work to members of industry and venture capitalists. Gebru won the competition, starting a series of collaborations with other entrepreneurs and investors.[11][12]

Gebru joined Apple as an intern while at Stanford, working in their hardware division making circuitry for audio components, and was offered a full-time position the following year. Of her work as an audio engineer, her manager told Wired she was "fearless," and well-liked by her colleagues

Yeah (in the US, depending on state) plus when you get paid off you get severance, maybe even unemployment. At least you know where you stand. If the bosses are truly assholes, you know where they are. I think it's entirely possible in many cases they just don't realize what they are doing. In another situation they might be truly wanting interchangeable low value programmer, so tell them it's not a good fit anymore, I'll help you hire my replacement, please leave me a good letter of recommendation on the way out, and you get that.

> The lights come on when people want lights, they turn off or dim when they want less light.

How do you imagine that to work?

I prefer the lights off, my coworkers want the lights on, so when I'm alone I leave the lights off, when the others come into the office they turn them on. This situation is very easy to deal with because fortunately we have normal light switches in the office.

There is no way that automation could improve this situation, unless they install cameras with facial recognition to see who is in the office today and send everyone questionnaires to ask about their preferred lighting levels.

Again, the goal is not selflessness, it's selfishness. The selfish want to form a more perfect union. No one is saying they want to give away half their salary for nothing, no one is expecting anyone else to do so either.

It's effectively a bunch of people who want a crowd funding campaign for a product to exist, and everyone else saying "if you want to throw your money away, here's a trash can". That's entirely missing the point and completely unhelpful. The goal is to make a collective investment and get something in return.

If we're being real, this group, myself included, is only one step removed from a NIMBY, but it is what it is.

Terra is a language that can also do that, and uses Lua as the metaprogramming language. Types are just Lua values.

But unfortunately, there's a lot of work left kind of half-baked so using the language is a pain... if someone invested a lot of time to make Terra work properly and added some tooling around it, wrote proper docs and so on, it would be a really interesting language.

Migrating from Flask to FastAPI
If you want to use wasm, just go and use it. You don't need every other site to do the same before you jump in.

Personally, I do think JS is a better fit than Rust or C for almost everything people do on the web. And the support in other languages is still too bad to use. But you can use it whenever you want, differently from a second language you may invent.
> My understanding at the current time is that a server can be run by a single random individual, they can read your DMs as they are not encrypted, and they can kick you off the server if you write anything the server operator does not agree with.

Yes, just like any service on the Internet. I really don’t understand how the fact that anybody can run a Mastodon/Web/email/whatever server makes the whole thing not reliable; you just have to choose a server that suits you.

Oddly enough any processing delay is good in an "AI" chat bot, within reason, makes it feel more natural rather than getting a response ping instantly. Chat version of uncanny valley or something, haha.

Something it also did in Markov form was pick randomly from the longest words in the sentence it had decided to reply to, build the rest of it from that, then run itself "backwards" from the picked word to a sentence starter word it knew.

"Exploitation" has at least two (IMO very different) meanings.

Even though most of the time "exploiting an opportunity" is neutral and "exploiting our workers" is either a scam or abuse, I have seen some texts that used the word in the same sense for both cases.
Energy is fungible, so if both fossil and renewables are both online and producing energy how can you blame one over the other? My understanding is that neither source of energy was winterized to transmit the energy to the grid, not that they were unable to produce. So blaming one or the other is a red herring.

> But unlike utilities under traditional models, they don’t ensure that the resources can deliver power under adverse conditions, they don’t require that generators have secured firm fuel supplies, and they don’t make sure the resources will be ready and available to operate.[0]

The question should squarely be "can renewables create the same base load and peak load required to run the entire demand of the grid"? From there than we can talk about the other topics such as what is required to deliver the energy, which is cheaper to operate, etc.

This is already how the price of labor in a global market works. In many companies, virtual workers are already paid on a scale based on their home market price, not the market price where their company is located. If that's how virtual economies are going to work, then it should at least go both ways.
That site is named after the practice, not the other way around, and the article is far more informative on how it all works (as well as the steps airlines take to combat it).
Yes, this exactly. There are still "threads" on Mastodon, but they're broken up on boundaries that make sense: related but standing-alone points. Mostly, you just don't have to think about it at all, and just write out whatever you're thinking. It's pretty great.

I agree cold has some effects on batteries, but the main impact on EV range is related to heating, so linking an article on EVs is not very useful when talking about stationary storage.

Batteries generate heat when charging and discharging, so grid batteries should naturally keep themselves warm, but maybe in extreme climates it would be worth adding some heat pumps to keep them in the optimal temperature range for longevity. It all depends on how the cost calculations work out, but it is not some major obstacle.

"base load power plant" is a meaningless term. Base load is a feature of energy demand. Power plants produce energy, the same power plant might serve peak load, base load, or both.

EVs are not a solution to energy storage. Even ignoring the challenge of getting people to hook their cars up to the grid, the battery production figures aren't remotely close to what we need.

People have been assuming that battery cost will continue to decline exponentially. We'll need a century to provision just 18 hours of battery storage at current rates. Renewable activists hand wave this saying that battery production will increase a hundred fold. In reality, prices are rising: https://about.bnef.com/blog/lithium-ion-battery-pack-prices-....
I think a good starting point would be something like a digital right to roam.

So you should not be able to enforce contractual terms, ask app stores or platforms to block, or use technical measures to frustrate access to an API.

If you expose it to the public internet you should be required to ambivalent about which software an otherwise valid use uses to connect to it.

I think there’s also a reasonable argument for some core protocols and services to be treats and regulated as a hybrid between public and private, kind of like the banking system.

I don't see what there is to understand.

Any 'ai' model right now requires classified data to train. It takes human work to classify data. Human work is cheaper in some places than others, so companies in expensive places exploit the situation of poorer places to lower their operating costs.

The wage size compared to the local economy doesn't really matter, since the exploitation comes from the difference in costs between the local economy and the local economy of the company.

In your reality, how is the data getting classified if not by people whose situation is being exploited?
