Chromium mining is crucial for the steel production industry because chromium is a key ingredient in the production of stainless steel. We've been hunting and mining it for a LONG time now. Stainless is important to so many preexisting industries, such as new construction, automotive, aerospace, and household appliances. Consequently, there have been shortages in the availability and mining of chromium and this has directly impacted the production capacity and quality of stainless steel in the recent market.
Seems solid-state battery production will be in competition with these industries and I would hedge a bet that Stainless Prices will go high in the coming decades as a reflection of the pinch on chromium.

Yeah I opted for quick, simple demonstrations of the basic ideas. In a real application, at least one of any significant complexity, I wouldn't be writing the code you see in those demos. I'm experimenting with how it might integrate with state management libraries, currently with mobx.

I haven't done any work on this front yet, but I'm especially excited to see how this might fit into an SSR/MPA app. I have some ideas though; my goal is to implement ISR/streaming/etc without the need for weird little conventions like "use server".

>What on earth has the corporate analytics team been doing all this time to not make that sort of opportunity cost screamingly obvious?

This is assuming there is an analytics team / department. I think people in tech may be surprised how Tech hasn't really caught on in many of the industry, especially those that are not Fortune 2000.
It is wrong and was debunked. Some people need far fewer than 10k and others never become good no matter how long. There so much variability it is useless as a heuristic.

In a free economy decision power over wealth accrues to those under whose watch wealth compounds fastest. You may disagree with the inequality that results but history shows it is difficult to compete economically with groups that run free economies.

Hopefully you can vote politically during elections, you can vote economically with every dollar you spend and you can vote with your feet by switching countries.

If you have an idea about some paradise that will operate much better under the economic rules you believe in ask yourself why this paradise does not yet exist if it is so much better. If your economic paradise does exist why not just move there? Surely those having your "wisdom" will be highly valued there.
The difference between -1 C and +1 C is VASTLY more important in daily life than the difference between 26.5 and 27 C.

That has probably never been the case for any product in any category. Your car can't fly, even though you think that the customer is always right.
On the surface, clojure.spec.alpha seems to handle things more or less similarly (you get random results skewing heavily towards small/trivial/edge values), but the main difference is that it can be used and abused without problem. As long as you can write predicates and compose specs, it handles it for you and “just works”.
Waymo has a huge potential totally addressable market. The possibility to earn money on every mile driven. Hardware costs are high now, but are on a very favorable curve for cost and capability.

Potential for Wing also seems good. Any delivery under 5 pounds an under 10 miles is going to be much faster/cheaper by air.
Yeah, totally fair point. I should probably add a simple guest access. Had to lock it behind auth as I keep adding features for myself that require some backend action, and was too lazy to write different code paths depended on authentication. I guess, that's also one of the drawbacks of writing something for myself, as you just forget about inconveniences that it can cause to others.

Difficult to determine absolute value, as unambiguous isomorphism manifests the same ideas in many specializations.

While some solutions may prove sub-optimal, a refinement process by its very nature emulates a reductionist goal without the confines of abstract contextual dependency or impossible to implement/prove rigorous meanings.

Except, I know how to slice and dice text with awk, and can do it without leaning on ChatGPT or studying language documentation. Never made the leap to perl, the few times I tried I was put off because to a newbie the language looks like gibberish.

I would never consider perl for anything new in 2024. I still use awk very regularly.
I wonder if the CLI could have a "watch mode" where it watches a file or directory, and automatically append the response as you edit and save a Markdown file. Not sure how well it would work in practice, but seems like it could be an interesting alternative to the "chat" format.
The morbid, mesmerizing beauty of AI gymnastics
If there are no infinities, then I am not sure why you brought up an infinite machine as an argument. The point is to imagine a being with orders of magnitude more processing power than our brains, it'd be able to fathom things we literally could not, even with any amount of slowness of processing. It'd be a physical limitation.

a different way to look at this is that, when we find a way to generalize a problem-solving skill, we call it math

if you can throw a spear and hit the mammoth, that's a problem-solving skill. but when we learned a technique that can calculate the trajectory of the spear, the effect of the timing of jupiter's rising and setting on mars's, and the penetration depth of a baseball into the water, that's math

> You're essentially arguing that King John should have exclusive right to publish books, and that he should be able to prevent the barons from publishing unapproved books - the DMA gives anyone the right to publish apps including you and I and Epic.

The thing I'm referencing is Magna Carta, specifically where the conflict was over "can the King force me to use his own courts when I sue him?" — this didn't much affect the normal folk who never had to personally sue the king in his own personal courts.

Similarly, I:

(1) already had the ability to publish an app, and have done so on many occasions

(2) still don't have the means to start an entire app store because the obligations vastly exceed my competencies (and I don't have access to one million USD): https://developer.apple.com/support/alternative-app-marketpl...

> I might agree that Epic should be prevented from publishing their apps, but by a Democratically elected government, not by a private warlord. If Epic is doing something wrong, that should be a matter of public law, not a matter for a king to decide.

Sure, but this is the kind of thing we could — and others have and will anyway even if we don't — spend lifetimes arguing over every single nuance and subtlely of, including the extent to which a corporation is allowed to have the freedom to decide its own rules for who it does business with e.g. all the things Apple is doing (and all that Apple wants to refuse to do), or if the owner of a cake shop can refuse to do business with customers whose morals it disagrees with, and so on.

The only thing I'm sure of, is that I can't see the consequences of applying my first principles as if they were universal truths.

Note that the knock-offs are clones of the original ~10 year old Salae Logic design, which also used the CY7C68013 without an FPGA (and had smaller margins than their current design, it only cost ~$100). They added the FPGA as a way of differentiating their products from the clones after they started becoming widespread.
My parents care a lot about "przymrozek" - which is when it gets sub-zero C at night and you need to cover the plants and close the greenhouse doors and put a heater there so the plants survive. They give warnings in radio when this happen outside of regular winter months.

There's also special warning for drivers if it was sub-zero because then the water on the roads freezes and it's very hard to break.

I'd say it's way more important a distinction than anything that F makes obvious.

Pause tokens [1] are directly dependent on the model recognizing whether the answer it arrived at is one it should "commit" to or whether it should abandon it and output a pause token instead.

Similarly if you ask ChatGPT about the current president of Numbitistan it will tell you that it doesn't know about a county with that name, rather than just hallucinating an answer. So it can at least in this circumstance tell the difference between knowing something and not knowing something.

Public Opinion, Racial Bias, and Labor Market Outcomes [pdf]
Just a few more thoughts to add:

When I see code like

count++;
setContent(<p key="counter">The count is {count}</p>);

I immediately think about how someone, at some point, will introduce bugs/weirdness where they update some state (`count`), but then forget to make the `setContent` call to update the DOM. That's a very useful thing that React's `useState` does; a single way to update the state that is guaranteed to always be synced with the DOM. Of course, I could make a `setCount` function to help abstract this, but that's more boilerplate and just more opportunity for someone to screw it up.

Another point related to scoped components: one thing that I saw happen in jQuery codebases (and I think the same would happen here) is that it's too easy to mistakenly write a rogue selector that affects some part of the DOM that is far away from what was intended. It's one of those great power = great responsibility things... but I think this power more often leads to complex and confusing code that is hard for someone to understand and maintain.

React can be frustrating at times, when it seems like it would be easiest for a parent component to directly manipulate some nested child (or vice versa), but I think this friction often just leads to code that is easier to reason over.
Ok, but if you’re comfortable using it, Perl is really fun, pleasant, and easy to quickly express ideas in. One of its conscious design decisions is to be flexible enough to rapidly bang out some quick hack you’ll never look at again in absolute incomprehensible gibberish shorthand, or to use in a very methodical, disciplined, and structured way — so if you write something unmaintainable, that’s because you chose to.

I haven’t turned to it as my first choice in years, but it still has a place in my back pocket for if I ever need a quick and dirty text munging Swiss Army knife.
> over many iterations!

Nitpick, but this is what I hate about AI today. I've sat there hitting the "retry" button for 30 minutes on the same 5-line snippet of Python code before; it's an awful user experience, if not slower than writing it by hand. It's really aggravating when people create grand demos of their model product, and then disclose it actually took 8 hours of hand-correction and elaborate model jailbreaks.

It all leads to me being so thoroughly unimpressed by AI programming demos. I almost wonder if the Windows Pipe Screensaver was faster to program in the 90s than it is today with AI assistance.

If that’s the case why do the Celsius thermostats I used while on vacation in Canada use 0.5C increments? The decimals are used, because the change between 25C and 26C is actually pretty big :)

In my old apartment, the difference between 73F and 74F was enough to make me quite cold or hot. And that’s a difference of about 0.5C. I’m not arguing that Farenheit is better, but I definitely do prefer it for setting my thermostat (which is a day to day thing) , but then again I grew up using it so that could be why I prefer it too.
Been there. It's harder to stop in the middle, that's the thing. If I'm slacking on HN and I get a real work task, I think "ah, time to be good and start earning my pay".

I’m not sure there is really more to say here. A lot of people don’t seem to like strong type systems very much either, but that doesn’t mean they’re not wrong. ;)

That said, it clearly has some interesting ideas! I’m just not sure I understand why the database needs to be the compiler. It seems like an awful lot of design decisions baked into the stack instead of offered as APIs or protocols. And it’s obvious that we can consider the filesystem itself to be a sort of database — Git famously is implemented entirely in filesystem semantics, for example, so it’s also not clear to me why this content addressing can’t simply be done in a cache dir, or some such, the way many build systems do for their compilation units.
It's not my approach, it's our approach. I don't like it either, but I also lack the determinate capacity to change it. It's easier to just acknowledge that nobody values anything besides greed and resource competition unless the monopoly on violence demands otherwise.
So first of all, thanks for writing the books. I'm a happy customer :)

Second, I felt a lot of empathy for this, having gone through a similar situation, ultimately the company getting acquired during the pandemic.

I've learned many things, but I think I can share one takeaway that might resonate in this conversation:

Know thy users.

Keep the people that are directly using the software in mind. In times of corporate strife: remember the users. Let their happiness be your guiding light.

There are real people that depend on the software we write. Regardless of how any corporate decision turns out, those people will always be thankful that you made their day to day lives a bit easier.

Find the disproportionate pain points. That one preference that were it defaulted differently would save 90% of users a one time frustration when on boarding. That one janky error message that no one understands. Fix that sort of stuff, the stuff that users are interacting with regularly.

At the end of the day, unless you're contractually entrenched at oracle levels, if the users aren't happy, then whatever corporate structure that puts food on your table probably wont do well. They may not do well if users are happy, but very likely wont if users are angry.

Any given change might not matter to your executives, but they matter to your users, keep them in mind and heart and you'll know what to do. And periods of corporate strife like in the article are a great time to actually get that sort of stuff prioritized, because no one can say anything else is more important.
Sounds cool, thanks for explaining! Looking forward to trying it out :)

This overtly binary and deterministic model is what the article argues against. I agree with them.

There's a tautological interpretation of what you're saying which, since it's tautology, is always true. It relies on "corporate benefit" being whatever the responsible parties in the corporation decide it is.

But in the more usual "fiduciary duty" sense where "benefit" means direct impact on the bottom line, then no, this isn't true. Corporations are run by people, and not only can those people decide to forgo some profit in order to do the right thing, this actually happens from time to time. A ratchet prevents movement except in the designated direction, or it isn't a ratchet: so a ratchet is a bad metaphor here.

But, as the article also argues, there's a decided asymmetry to the flow here. Proposals which benefit the bottom line are easy to make, and easy to achieve buy-in on. Ones which have the opposite effect cost reputational capital, they're risky. So even a well-meaning corporation which is entirely owned and operated by people with a firm commitment to a vision of corporate benefit which isn't blindly determined by the bottom line, will miss opportunities to fulfill that vision which would negatively affect that bottom line, for structural reasons.
> If that’s the case why do the Celsius thermostats I used while on vacation in Canada use 0.5C increments?

Probably because they were made for US and changed the labels? I've never seen a thermostat with 0.5 C increments in Europe.

> the change between 25C and 26C is actually pretty big

I would maybe be able to tell you if it's 23 or 27, certainly I can't tell 1 C difference.
It makes no sense because it indeed makes no sense. People who successfully solve realworld problems understand concepts and ideas and how to apply them, they understand how to iterate and extrapolate.

I've met too many people who can do a specific thing but actually have no idea what's going on for the GP's logic to hold any water at all.
From the article: it was tested only to 100 cycles.

So this is experimental and a product version won't be available for a year or (likely) longer. And as products naturally niche into longevity, weight, capacity, and other categories, those metrics will become relevant at that point. Until then, it's just experimental results with metrics relevant to previous experimental results.
Came for this. I once talked with Harlan Ellison. He called my house when I was 17. At 2am. This was in the days of sharing a phone via a 30ft cord and taking it into your bedroom and closing the door. As teenagers would do. Martin H Greenberg and his family were staying at our house. He was calling for Martin. I was big into SciFi and had read a few of his books. The conversation was odd. I said Martin was asleep and asked who he was. Everything after hearing his name was sort of a blur. Yes, I did wake Martin and hand him the phone. It was hard to sleep after that.

No exaggeration; I know things happened and I remember emotions and feelings but rarely specifics, like what a person said or other details that make the event more memorable.

I think it's more about the long tail of situations that I'm not really able to imagine, or feasible emergencies but ones where my assumptions aren't valid. So not about a specific situation, more on principle that I want to keep my "get the heck out of dodge" energy store separate from my "hunker down" energy store.

I admit it's less efficient to have 2 energy stores, but given we're already discussing potentially life threatening situations, I'm not really looking to optimize for anything except having as many resources as feasible on hand.
