I inferred that what they meant was that the price and supply of iron and urea are unlikely to be greatly impacted by political or capitalistic issues, since they are so abundant.

Admittedly, price swings of several percent are easily imaginable, but for now we're making 280-300 kilotons of rare earth magnets every year.

A ton of urea is $300-$500, a ton of iron is $100-$150.

I don't know what the ratios are or processing fees or anything else, but if it took 1 ton of each to offset 1 ton of rare earth magnets then raw materials cost of replacement for the entire world's rare earth magnet supply would be less than $200 million dollars each year.

Not a lot that that can sway in any direction, especially when compared to Neodymiums' ~$2/oz price (or ~$77,000/ton)

Considering that Neodymium is 29% – 32% of a rare earth magnet, that means we spend $2.7-$6.9 billion/year on raw neodymium, so if this were the end of things we could expect a significant decrease in the cost of electric motors and other magnets at this level.
If you're looking for a typewriter with a light touch, the Olivetti Lettera 32 and Underwood Universal are some of my favorites. I love my Remingtons, but all of mine (all of which are 1940s models) are pretty heavy.
AI Link Bait Software Tools Generator
Dall-E 2 was almost immediately displaced by MidJourney. Nothing comes close to even GPT 3.5 at the moment.
Our free tool instantly provides unique and compelling link bait ideas, designed to maximize your blog's visibility, drive organic traffic, and elevate your SEO game.
The answer really is chaos. Chaos has different definitions used by different authors, but a characteristic they all capture is sensitivity to initial conditions. This requires inherently unstable dynamics (convergence to a fixed point or limit cycle corresponds to an insensitivity to initial conditions)
It’s also important to distinguish between microscopic and macroscopic equilibrium. The system shown in this video seems, at least informally, chaotic at the microscopic level (the dynamics of each particle). However, if you consider the dynamics of the distribution (i.e., the ensemble of a very large, ideally infinite) number of balls, it is well known that this distribution converges to an equilibrium distribution known as the Gibbs measure [1].

[1] I’m on my phone and not thinking too hard, you may need to add some Brownian noise to the dynamics for this experiment, but the double-well is commonly used to demonstrate this behavior.
It's worth noting the difference in how the training material is sourced though, Midjourney is using indiscriminate web scrapes while Firefly is taking the conservative approach of only using images that Adobe holds a license for. Midjourney has the Sword of Damocles hanging over its head that depending on how legal precedent shakes out, its output might end up being too tainted for commercial purposes, and Adobe is betting on being the safe alternative during the period of uncertainly and if the hammer does come down on web-scraping models.
> Constantly having to rebuild containers to recompile dependencies;

How often is this actually necessary? I've had projects that stick with the same dependencies for weeks/months and don't need anything new added outside of periodic version updates. There, most of the changes were the actual code, that was needed for shipping business functionality.

Furthermore, with layer caching, re-building isn't always a very big issue, though I'll admit that the slowness can definitely be problematic! Except for the fact that you don't have to pollute your local workstation with random packages/runtimes (that might conflict with packages for other projects, depending on the technologies you use and what is installed on a per project basis or globally), and the fact that you get mostly reproducible environments quite easily - both of those are great, at least when it works!

> ...dealing with permissions differences for volume mounts;

This is definitely a big mess, even worse if you need to run Windows on your workstation for whatever reason, as opposed to a Linux distro (though I guess WSL can help). I personally ran into bunches of issues when mounting files, that more or less shattered the illusion of containers solving the dev environment problem sufficiently: https://blog.kronis.dev/everything%20is%20broken/containers-...

But for what it's worth, at least they're trying and are okay for the most part otherwise.
The fact that it's wireless is the scariest part to me. What if it runs out of battery? What if it desyncs?
Exactly, web 1.0 succeeded because it originally was just regular people making their own pages and just having fun. It wasn't about making money, it was about connecting. You're right, the push to monetize the web was the downfall of web 1.0 and probably the web in general.

I miss an open web :(
Did you need more evidence? It seemed clear from the start - these were not trustworthy businesses.
Haha, spicy. We definitely don't want to overlook nix. It's a great tool. We do mean something different with "developer environment" in that context of this quoted sentence. I'm not sure if nix will help you much if you want to connect your VS Code to a remote VM or container to work inside of that environment. We'll work on rewording this though to make things clearer :)
Given that almost all of that is violates securities laws, this still fits.
lately ive actually been wondering if im more extroverted then I realized, but just have social anxiety that leads to me being quiet and reserved. I mean were posting on forums, i threw a party this weekend. lol
The filesystem bridging between Crostini, the rest of ChromeOS, and Google Drive is brilliant. It also transparently integrates SSHFS into the filesystem and the file browser.
You should try to get that into Busybox!
It's what I've internally compared every keyboard to ever since; I also miss the hum.
20K bonus and promo on top of existing TC and perf incentives is not bad at all.

Also, depending on their level, “creating GitHub Copilot” might actually be part of their baseline role expectations.
Ask HN: Would anybody be interested in a series of primers on HS maths topics?
So with my exams coming to an end and a rather long summer beginning, I wanted to put my time to good use and work on something that people find useful.

I've come across various HN posts where folks said they were trying to relearn maths from school that they missed out on due to poor teachers/resources etc.

I love pure maths and over time I've learnt gained a strong intuition for high-school level calculus and analysis so I figured I should put my knowledge to good use and create a series of blog-style posts(which will be free because I'd like to make this available to everyone I can) which will teach ideas in a rigorous and complete way while still being accessible.

So I guess I have two questions:

A) would you be interested in such a thing?
B) if so, what are the sorts of topics you would like to see?
He didn't say that, he said it's the killer app. It's the only value add over traditional finance.
Very much so: https://pinkerton.com/
Or trying to escape inflation/corruption? Please look into how the government there has brutally mismanaged their currency. People are suffering there because of monetary policy, empathy is a good practice.
How comparable are the competitors, though? The article notes that it is warehouse and delivery workers. Many warehouses won't be managing their own transportation fleet.

Amazon does appear to be comparable to FedEx, UPS, etc. Fact of the matter is that driving is just plain dangerous. Trucking is indeed considered one of the most dangerous jobs in America, and I'm sure that surprises nobody.

So Sanders isn't exactly wrong to say so, but the presentation seems a little misleading or disingenuous. What should Amazon do with that wealth to make the roads safer, exactly? Transportation is under purview of the government.
> No one is having issues with police if they aren't breaking the law

yes, they are. that's why there's "animosity of the left-wingers about police."

> 1. You are not allowed to setup a tent on the street. You must stay in housing provided by the government outside of the city in a cheap area. You will be given free transporation there.

and what about the residents that already live in that "cheap area"? who pays for the construction of the housing - the people within the city limits or the people living in the cheaper area?

> 2. If you are a repeat offender found to be sleeping on the street, then you will be arrested, and imprisoned.

what if it's a family who lost their home? do you separate the children from their parents for the crime of being too poor?

> 3. A mental health disorder is not an excuse. If necessary, build a jail that is a mental health treatment center.

great - how long are you imprisoned if you have a mental health crisis?

> What is the worst thing that happens from this policy implemented fully?

abuse by law enforcement; imprisoning people who need mental health services, not to be locked up with actual criminals; the separation of families who have fallen on hard times; criminalization of poverty; short-sighted solutions which don't actually address the core issues.
I'm not a Car Person (I hate cars, electric ones included), but what I often hear said is that they feel very cheaply made, in terms of fit and finish, both interior and exterior. Panel gaps, water leaking into the trunk, squeaks and rattles. Mostly not very serious (not powertrain issues or anything), but nevertheless, not something you want to see on a car you're paying as much for as a Tesla.
With crypto trading platforms, the SEC lacks any sort of oversight and access — and has scant ability to detect, investigate and deter fraudulent conduct. As a result, the crypto marketplace operates without much supervision

Isn't that the main idea of a decentralized currency?

No doubt this has/does/will harbor criminal activity, but it will also foster the ability to exchange goods and services without third parties. This has huge benefits when the third parties are rogue and overextend their surveillance. Freedom is what we should be after. This has a cost in terms of criminal activity -- even to the extreme.
I’m not clear from the article. Was there a warning light to not go near the plane, but the user ignored and got sucked in? Or was something wonky with the warning light.

I think the behaviors should be a bit different in those two cases.
Have you ever been to a Canadian Tires?

CTM is used the same way you'd use Airline Miles or Credit Card Points.
I kind of feel the same as your friend. Whataboutism is thrown about like a pejorative, but if I’m playing cards with a table of cheaters, I’m going to start cheating, or I’m going to get cleaned out. If someone tries to call me out, it’s fair to ask him to roll up his own sleeve. And this is a game that you can’t just walk away from.
Haha gotcha, but Huren also means renting in Dutch (with no other connotation AFAIK)
Brake cleaner is the worst, the others are pretty much okay as long as you avoid exposure. ATF, Oil, etc - just wear proper PPE :)
I love that people are finally realizing the importance of enforcing invariants in the type system. Linear types, Uniqueness types, Affine types... I love 'em all. ~~Hopefully somewhere in the future people realize even more the importance of pure FP~~
That doesn't mean they can take your money for no reason.
isn't this what Micro$oft have always done. The big behemoth bully picking off the little guys with there "Too big to fail" approach to business. relying on the fact that large companies think and dream in grey than in color.
Not if the intention is to drive crypto into the ground first and destroy the initial sector players (eg Coinbase), so the establishment banking / finance system can recapture all of it in one swift regulatory move.

It would then be ideal to be entirely out of crypto until the destruction is largely over, and the establishment gets its lock on the market.

There were only ever two possibilities. They control & own it, or it doesn't get to exist legally. Everything else was naive fantasy and ignorance about how the world actually works and will always work (power, politics, guns).
Or to put it another way, the police exist to ensure everyone knows their place, and stays in their lane.
I reject the idea that a terrible UX is an integral part of Linux.
Okay yeah sure, technically. In practice, you have little to no control over it or your audience and good luck migrating it when you feel like it or when the platform turns hostile.
I hope I am wrong on that, but this is exactly one of the two largely unaddressed problems for a complete change to an EV fleet in countries like Germany. 1) Do you have enough power delivery available, especially with the push to electric heat-pump based heating. That seems to be a serious problem, I heard from some people that they are not allowed to connect their heat-pumps, even in newly constructed areas! Solvable, with political will, but I don't see the will. 2) Where will people charge who park on the streets. It seems there are technical solutions (electrified curbstones), but again, political will to change much infrastructure is required.
Current reservoir capacity lasts 3 years during a drought at normal water usage. Agriculture uses 92% of all the water. There's absolutely no need to "ban farming". Lmao. It would be vastly cheaper to build a few more reservoirs and increase our capacity by 2x or 3x.
Well, you just said that's he's wrong. One "killer application" is that it's a "stable" store of value. Not perfectly stable, it can quickly fall by a factor of about 2, and if you buy in the worst bubble it might fall to a fourth of its value. That's decidedly less stable than Western currencies, but it's more stable than some others. And for many people Bitcoin is more accessible than the foreign exchange market. It also tends to rise in value over sufficiently long time scales.

The other use is providing online payments to people who aren't in the banking system. The banking system requires trust, and shuts untrustworthy people out - both at the level of individuals and entire regions. Bitcoin eliminates the need for trust (on the monetary layer) and can thus reach more people.

Both are great applications. They are largely irrelevant in the West because only a tiny fraction of us experience those problems, but that doesn't mean they don't exist elsewhere.
Well said and matches my experience as well. A breadth of features but once you start actively using them in depth you find that the experience is not as polished.
Different board, same company
I love hearing this! (My friend and I built Campnab.)
guessing the sudden imbalance of salts between the body and the incoming pure water would cause some reaction, maybe it triggers some sort of 'poison' response? that would cause vomiting too though
I live in one of those states and am visibly nonwhite and haven't stepped inside a church in a long while. Life is great here.
Honestly, probably not. Even in WW2, the closest there got to 16-year-olds fighting (at least without lying about it) was in the Home Guard (sometimes called the Dad's Army because of its use of retired soldiers), and them fighting would mean the enemy landed on Great Britain itself. It's not impossible, but I imagine something similar would happen in almost any other country under active occupation. Which doesn't mean I think it's good (or bad), I just think the UK doesn't stand out.
Just a nit pick: 10A @ 240V isn't enough to charge my Tesla Model Y overnight from empty - but 30A @ 240V (7.2kW) is.
Lighting also tends to be pretty bad in complex scenes. I find the unrealistic shadows tends to break the photorealism of few light source scenes.
I wonder if the SEC knows how to use a blockchain explorer? That claim is made false from a simple glance at one.
As 'zokier pointed out[0], we live in the age of apps. If you're not allowed to use this tool for collaborative process, often enough you may just as well not use it at all - as moving data between apps is usually a manual process that's boring, time-consuming, and lossy. Modern apps are tools of control, not cooperation.

Most people don’t need Tesla range. The MINI Cooper does 114 miles for under $30K, and Hyundai, Kia and Ford all offer 240 mile + ranges for under $40K.

Tesla Model 3 has 270 miles on the base model but you’re paying over $40k for that.
Yeah, Tacomas are weird hybrid trucks. It's a full sized truck in every way except the bed. The loss of the smaller truck like the S-10 makes me sad. I miss my S-10.
It’s sort of tough to gauge one way or the other - the lighting components seem to work well (and it’s probably LED) why does it matter the supplier? Just depends what your standards of “jerry-rigged” is - for us “hackers” on HN we may have a higher threshold and it’s not like this sub was “duct taped with bailing wire”.

I think of jerry/jury-rigged as literally a boat mast that’s snapped and is reattached by any means - comparatively this sub is polished.

I wouldn’t go down to see the titanic on this thing though but would probably go for a short test.

Edit: needless to say this isn’t the time for “told ya so” wishing the passengers and recovery crew the best
The essential point is that they are not ruler or lords or saviors. We hired them to work for us, and democracies turn out to work better than any other form of government in history (and it's not close).

We are the rulers, lords, and the only hope for our own salvation. You'd better get to work.
I don’t know, I’m relatively certain securities laws do not affect me.
Why? Because some of those children who supported the platform while playing games with friends are now adults and putting their projects behind it. I am so disappointed Discord took off. What an absolute privacy nightmare of a site. It boggles my mind people are working on projects with open source components/ideas and then forcing people to sell their soul just to read a CHANGELOG or find some simple instructions.

I agree with others, forum management was pretty difficult due to spam. But it feels like we could have come up with something else instead of just going all in on Discord.
Banks work fine now for payments. The only real advantage of crypto over CBDC is that you can more easily sell drugs and guns. No one is losing their bank account for donating to Donald Trump
Who is this?

Edit: Seems like some online money making huckster who is now also a rapist?
Best AI Chrome Extensions for Developers
> Clicking or tapping things on a screen is an intuitive and essential aspect of user interaction that should not be overlooked.

I don't know, is it? Humanity made do without it for thousands of years.
I have. What I've observed more is outside attackers with their own agenda use the "nobody objected because they were unprepared and unable to respond in the 2 minutes I gave them to object" as proof their agenda is supported.
I've leaned harder into stuff like degoogled Android since app providers started to get obsessive about unrooted phones.

I'm sorry, but no, you don't need to halt execution simply because I'm an admin on my own device. Particularly if I can do exactly the same thing by just using your web interface (90% of the time this is available).
They do. The SEC pays competitively and there are a lot of crypto adept people who feel there is also a case for regulation in the space.
personal reflections from interviewing him:

- Idk how to say this but surprisingly not arrogant. we both prepped by watching his lex fridman and prior livestreams, so its not like we were dealing with an unknown quantity, but I've never seen him interact with "normal" (technical, but not his level of technical) people like us before. he was pretty patient I think, except I definitely got roasted for suggesting you could jailbreak the tinybox. instantly regretted it but he only joked once aboout it which was super cool :)

- quite reasonable expectations for his AMD frustrations. the fact that Lisa Su got personally involved and they listened was also fantastic. this isn't a "tech diva flipping the table because they stubbed their toe" story - AMD was found wanting in basic documentation requirements, he raised the issue, they took a while but eventually fixed it. Great partnership all around imo

- hiring in the age of AI is really going to get strange. he thinks we're ~20 years out from developer jobs being gone. Yes he is essentially asking people to do work for small bounties. in some circles, that's a no go. but it basically guarantees that the candidate will be a fit, and is fine if you want to keep the team tiny anyway. he also changed his mind on remote work which is cool.

- this was the first time i heard anything materially different about GPT4 architecture being a mixture of experts rather than a 1 trillion super model. does raise the question about what GPT5 will be built on if we have indeed run into the limits of scaling model size.

- notes to future interviewers: george is ultra open (he identifies strongly as a streamer, is very comfortable with what he is saying and doesnt need a ton of prep or post recording review) - just be super attentive to what he does and does not want to talk about and let him riff and he will indulge. i think we were maybe like a 7 out of 10 on getting the best out of him, but hopefully we will be a lot better by the time we go down to San Diego for the tinybox launch :fingerscrossed:

- He gave us advice on whether or not we wanted to go big and be the next Lex Fridman or stay niche and I think we were pretty convicted on wanting to stay niche and technical. To my knowledge there's no other podcast in the world that could have had this deep-but-still-kinda-accessible conversation with George and I strongly feel like something like this has to exist.
Stupid question, perhaps: was/it possible for this sub to have any kind of beaconing or communication system that works at depth? It seems like one of this first things I'd investigate before deciding to build a sub.
I've had two of those exact gamepads die
I think a lot of the answer is 'chaos'. Most nontrivial systems are chaotic (generically, iirc more than 3 unconstrained d.o.f. + non-linearity) and most chaotic systems quickly erase knowledge of the initial conditions (https://en.wikipedia.org/wiki/Lyapunov_exponent). That being said, within chaos, there are fractal regions that survive pertubations (https://en.wikipedia.org/wiki/Kolmogorov%E2%80%93Arnold%E2%8...) and this is indeed related to why the solar system is more stable and predictable (can read about KAM theorem and Jupiter).

In the bouncing ball example, there are periodic orbits that are created for some balls, in which case you can perfectly predict their past and future. But a lot of measurements we do make about the world tend to be statistical measurements that don't depend on measuring the precise trajectory of individual particles over long periods of time. So these issues tend to not be important unless precise details are needed.
Raising during this downturn time on a business that is not AI nor crypto is fairly amazing though.
And then they wonder why regular consumers aren't fleeing banks to start using crypto for everything.

I've yet to see cryptocurrencies actually solve a problem that your everyday average person has when buying groceries or going out to eat.

They just make things more difficult and confusing, and all these attempts to alleviate that just lead us straight to "banks, but worse".
I'm presuming you're not including Stable Diffusion when you say this; the fact that SD and its variants are defacto extremely "free and open source" presently put it way ahead of anything else, and are likely to do so for some time.
How is the range when pulling your trailer? From what I read the reduction is steep?
