Hi, I'm the @andrewrn mentioned.

For those interested, I did polish the initial app a lot: https://fermi-game.onrender.com/ (bad news though... I over-engineered it even further I think. It's my first real public project, so I learned my lesson to viciously descope the mvp). Some of the comments here (like scientific notation and sharing) are present in my project. I tried to re-share after polishing but the HN link sharing dynamics have been a bit opaque to me and kept the project buried when posted.

It's clear to me that there is a lane here for a fun brain teaser/exercise. Just getting the answer right on 2 tried on OP's version by guessing ~5% of 330M population buying new car was a nice hit of dopamine. Combining a little math and world-knowledge is pleasing, it would seem.

@danielfetz, any interest in collaborating?

I spoke to them a lot at OpenSauce.

- The body panels were composite but they want to go to stamped metal for production. - It's based off of the subaru ascent; at least most of the frame and suspension is. - NMC chemistry, didn't get an OEM name for the actual cell/pouch though. - Mostly off the shelf Bosch power-train components. Will be interesting to see a tear-down once they're for sale. - No commitment on how "open" the vehicle will be to modifications. They have designed in attachment points for upgrades but it didn't seem to be anywhere as extensive as what Slate is doing. This makes some sense; they have a more "finished" vision where Slate is intentionally taking the "our vision is for you to buy the canvas from us and then make it your own" approach.

On that last point, I don't think Slate has released anything substantial either w/r/t the CAN bus either. As far as I know, their plan is still a BYOD approach for the head-unit so here's hoping that it'll be relatively straight forward to interrogate the busses from an android or linux device. The Telo had a head-unit integrated so who knows how much control you'll have over the vehicle.

You really think that there are there isn't a large percentage of the population that wouldn't reject AI connection merely on principle?

Just from the first survey I could find:

> In the Common Sense Media survey, 31% of teens said their conversations with AI companions were “as satisfying or more satisfying” than talking with real friends. Even though half of teens said they distrust AI’s advice, 33% had discussed serious or important issues with AI instead of real people.

Well, the code wouldn't be representative of the new frame, right?

For example, you encrypt the hash of the frame itself (+ metadata: frame number, timestamp, etc.) with a pkey. My client decrypts the hash, computes the hash and compares it.

The problem might present itself when compressing the video but the tagging step can be done after compression. That would also prevent resharing.

Thanks so much for signing up and sharing this with me.

When you say "not sure if related" I would say most probably yes. Most emotional issues come from our childhood. It's interesting that your parents are German too. There have been a few other Germans that said the site didn't work for them and they have trouble crying. Seems like definitely a cultural thing there.

Many of us as kids are told things like "don't cry, cheer up, calm down" etc, etc by our parents and other adults who we are desperately seeking approval from and reliant on for care and survival. So we may not even realize it at the time, but we conform and change to please them. We feel like we need to be a certain way in order to receive their love and care and attention.

I think the answer could be in that one day you suddenly stopped crying. It's interesting that you say you're not sure why. Sometimes we can forget moments like this because they can seem insignificant at the time but they actually are meaningful. Sometimes it can be more difficult than people who experienced something super traumatic and are able to pinpoint that that was when things changed.

What often happens is we either experience or suppress an emotion without much awareness, and rather than letting it pass or move through us, we ruminate on it and get caught in emotional loops. Then that emotion or the suppression of it becomes a mood. Then that mood becomes a personality trait. Then that personality trait becomes who we are. And years later we can find ourselves wondering why we feel the way we do or how the hell we ended up this way, because it was something that started when we were kids and we didn't understand how all this stuff works and unfortunately no one really told us or guided us.

I'm really excited for you to try the app. We are designing it so you can input things like this and it can help guide you to deeper understanding while processing and releasing necessary emotions. I'm building it for people like you where you are now, and also for younger people so they can catch these issues before 40 years fly by without shedding a single tear. It's never too late though. It's great that you are recognizing all this and I hope the app is able to help you.

I bet there are more professional footballers than AI researchers hence AI researchers will tend to get paid more.

Also much more people are affected by whatever AI is being developed/deployed than worldwide football viewers.

Top 5 football leagues have about 1.5billion monthly viewers. Top 5 AI companies (google, openai, meta etc) have far more monthly active users.

250 million probably gets you a couple of research labs and incremental field advances per year?

Assuming a lab has 20 phds/postdocs and a few professors, call it 25 people per lab, and you're compute / equipment heavy, getting you up to an average of 1M per person per year in total fully loaded costs (including facilities overhead and GPUs and conferences and whatnot), then you're looking at 200 PhD researchers. Assuming that each PhD makes one contribution per 4 years, then that's 50 advances in the field per year from your lab. if only 10% are notable, that's 5 things you've gotten that people are going to get excited about in the field. You need 2% of these contributions to be groundbreaking to get a single major contribution per year.

So 250M for a single person is a lot, but if that person is really really good, then that may be only expensive and not insane.

Cool but ... this also sounds like hording behavior. The number of things I've saved over the years only to throw them away years later and realize that saving them in the first place was a waste of time.

In the 90s my friend's mom would video tape AMC movies. She had 300+ tapes. Maybe she had a few rare ones but now all those movies are available on demand either legally or illegally and in much better quality. Another friend kept all of his 1980s computer magazines (Byte, etc...) and moved these extremely heavy boxes through 30+ years of moves. I doubt he ever opened a single magazine since the moment he saved them. Then they all appeared on The Archive and he finally got rid of them.

To be clear, I have a few youtube videos saved on my local storage. I'm just thinking that saving every video I watch reminds me of the things I've personally over-saved.

Actually that reminds me. I met up with the magazine saving friend recently which is when I verified that he finally got rid of his stash. It made me think about things I'm still saving that if I reflect on I know I will never actually look at. For example I have box of about eight 3.5 inch floppy disks from my Amiga days. The odds that I'm going to get an Amiga or download an Amiga emu and get a drive to read those are close enough to zero that I should throw them away. Similarly I have a book of CD-ROMs of backed up data from the 90s. There's a close to 0% chance that I'm never going to bother look at their contents.

On my trusty T42 (bought ~10 years ago for about 30 euros) the GPU finally died last winter (heavy, unreadable screen flicker during every slightly more intensive task). It has an IPS panel which itself still seems to be in order, though. Luckily, I accidentally saw a similar one (no IPS, though) for 26 euros, so I'm rocking again.

Those 4:3 screens and T4x series keyboards are really hard to let go, and if your activities allow for more text-oriented operating systems (I installed 9front on mine, but used to be a dedicated Tinycore Linux user, and the T42 is also nice with the various open source DOSes we have these days), they're still perfectly capable machines for 90% of relevant tasks. CF cards make very nice poor man's SSDs, so the machine is also very quiet with this setup, so far the fan rarely turns on.

As for my previous T42, I think I really squeezed a lot out of it, including using it to produce (and, on a few occasions, record live) 1-hour radio shows for my country's public broadcasting (honored to contribute to a "landmark" series where high production quality is a must). It was always fun to think that here I am, working on a 30€ 15-year-old machine, whereas other guys are doing their exact same montages on 2000€ Macbooks -- and regarding the resulting production, the radio listener will notice no difference whatsoever. :)

Obviously, though, this is a geek thing, those Macs probably do make a lot of sense for serious audio production.

It's completely crazy, though, how you can get a more or less perfectly working (!) Thinkpad for 25-30 euros, whereas that same brand new machine cost something like 2k in 2007.

Agree strongly that historical integrations were great. But cortex platformization of all the things has not been well received. But PANW is doubling down on it.

It's also curious because their firewall platform seems/feels totally separate from the rest of cortex still.

I will say, they do have a ton of coverage, more so than any other single vendor I can think of.

One _surviving_ evolutionary form of life. And it barely survived through mass extinctions that ended the majority of the existing life during those events. For all we know the great oxigenation event could had ended any of the alternative life by then.

In any case, the existence of life, or the emergence of intelligence should not be considered a necessity. Intelligence was the way of surviving and keeping on the race for the particular conditions we had a few millions of years ago. And about life, it could be more rare than what we think, just that we are doing the question where it managed to succeed.

> Last I checked Telo has... one prototype?

As of OpenSauce last month, they had 3 that were roadworthy. I think the company is 15 people big so it would be odd if they had a fleet with mfgr/prototype plates.

They were cagey on their manufacturing strategy but I got the sense that it'll be mostly contract manufacturing. I think slate is trying to keep as much in-house as possible and that means saying "no" to some design decisions that would require a step-up in terms of manufacturing capabilities. E.G.: Composite panels are a hell of a lot cheaper to make than stamped metal panels so slate isn't going to contract the metal stamping out.

It's just a tool, not an intelligence or a person.

You use it to make your job easier. If it doesn't make your job easier, you don't use it.

Anybody trying to sell you on a bill of goods that this is somehow "automating away engineers" and "replacing expensive software developers" is either stupid or lying (or both).

I find it incredibly useful, but it's garbage-in, garbage-out just like anything else with computers. If your code base is well commented and documented and laid out in a consistent pattern, it will tend to follow that pattern, especially if it follows standards. And it does better in languages (like Rust) that have strict type systems and coding standards.

Even better if you have rigorous tests for it to check its own work against.

They have to solve a real problem for people hauling cargo, they don’t really do that as they currently exist. They get significantly worse range when hauling than a normal gas or diesel truck, their only benefit is making feel better about their carbon footprint.

I was legit considering getting an F150 lighting for a little while but when I saw how much your range decreases when towing something it became obvious that it’s not really practical. It’s just objectively worse at hauling than a gas car.

Hopefully we see more battery tech breakthroughs that make electric trucks viable work vehicles.

No, of course they don't. This is Sam Altman's fusion company, backed by Microsoft in 2023 with a signed power purchase agreement: either Altman has some serious dirt on Satya Nadella, or (more likely!) Satya Nadella is a gullible idiot who thought "Sam Altman is the Boy Genius Who Invented AI, so he can solve fusion too!"

(Remember this is same same Satya Nadella who offered Altman an unspecified CEO-level position after he got fired... while publicly admitting he didn't know why Altman was fired! If I was a MSFT investor I would be pretty upset about this.)

Presumably 2025 MSFT is more sober-minded about Altman. I wonder if they're gonna try to wiggle their way out of the PPA. Otherwise I am truly baffled.

> I see them in pristine condition on city streets hauling a totality of one human.

It’s about having one vehicle that can do it all. Maybe you’re noticing when there’s one human but you don’t really know how else that person is using the vehicle at other times. Trucks can haul people, things, do road trips, etc. pretty well.

I think that we can demand that our education systems teach our kids to read and do math.

Many parents are not academic and can’t do a good job in passing on academic skills no matter how hard they might try. Many other parents would prefer to teach their kids different things about how to live a life.

I grew up on a farm, and the start of my journey into tech was fixing machinery and building things outside with my father. With my kids I want to create a similar experience so they feel like they have the power to take things apart, fix them and make whatever they want. I don’t want to jam them up all evening reading and doing times tables.
by CamperBob2 | 2025-08-02 18:58:27+00:00
The correlator is interesting. I don't see how it works. In the perfectly-tuned case, how does delaying the signal by half an (IF?) period and inverting it yield a match for the original signal? Inversion isn't the same as a delay.

I guess the idea is that the 70 kHz IF is effectively sampled at 2x the necessary Nyquist cutoff needed for 15 kHz baseband audio. So the signal content at half the period can be relied upon to match after an inversion and delay, assuming it was (a) band-limited at the source (or by the clever deviation-reduction scheme), which it would be; and (b) tuned correctly.

This is cool I guess but I don’t get why some of these electric car companies have to design cars that look like toys. Rivian and this. It looks like a golf cart with a flatbed. I think an electric kei truck would have a huge market in the US but the design needs some work to be taken seriously.

There’s something to be said for being distinctive, but you can do that while not looking silly (Lucid is a good example). And simply being a small electric truck is enough differentiation anyway

Congrats! Nicely done! Conway's Game of Life was my first attempt at assembly programing for a self-soldered ZX Spectrum's Z-80 CPU clocked at 3.5 Mhz. Compiled to 383-byte long binary, managed to do about 100 generations per second for a 3-cell blinker oscillator. My friend did a naive BASIC version brute forcing every single pixel on the screen, doing about 1 generation per 2 minutes. I started from BASIC version doing about 1 generation per 3 seconds. The main algo optimization was to have a list of active cells and only processing directly adjacent cells, and ignoring the majority of unpopulated white space. The next optimization was moving cells processing to assembly (the 383 bytes module). It was also toroid-shaped field, exactly like in your implementation. We had a lot of fun watching all those oscillators and guns producing gliders.

Hey HN! Thought I'd share this side project I've been working on in the last couple of weeks: 4 AI agents play the classic board game Risk, with make belief personas (Genghis Khan doing great, Captain Jack Sparrow not so much) and randomly selected models.

I added the new "cloaked" Horizon Alpha model last week, and it has been absolutely decimating the competition (I've also just added Horizon Beta, so we'll see how it does).

It's a lot more fun than a robust experiment, but I've found the interactions really interesting. If you'd like more detail, you can also read my blog post here: https://andreasthinks.me/posts/ai-at-play/

I feel like some of the cultural outrages and doomerism are getting ridiculous. People do not drink as much alcohol as they used to, we are doomed! People actually avoid situation that make them drink and drive, we are doomed! Teenagers have less sex then before, take less drugs, commit less crime, we are doomed!

Cant wait for "kids play less videogames, we are doomed!" round.

I'm not aware of Helion publishing any peer reviewed data claiming a physics breakeven (the point where the total energy generated by the reactor exceeds the external energy fed in to maintain the reaction going); let alone an engineering breakeven (the point where the fission generates about an order of magnitude more energy, to allow for the energy conversion losses, cooling and fuel breeding etc. so as to actually output any useful amount of electricity); let alone an economic breakeven, where the reactor generates sufficient useful energy that its market price can allow the capital and operating costs of the reactor and associated infrastructure to be recovered in a certain number of decades.

If fusion had all three today, it would still e a though sell; fission has them and is still failing economically.

> 5. Monolithic with docker orchestration: I essentially 10x'd when I started letting Claude itself manage docker containers, check their logs for errors, rm them, rebuild them, etc. Now I can get an entirely new service online in a docker container, from zero to operational, in one Claude prompt.

This is very interesting. What's your setup, and what kind of prompt might you use to get Claude to work well with Docker? Do you do anything to try and isolate the Claude instance from the rest of your machine (i.e. run these Docker instances inside of a VM) or just YOLO?

That is the self-interested feeling that Open Source preys on.

And I do mean "prey" with a negative connotation. One of the biggest perks of Open Source from a company's perspective is that you can get developers to work on your project for free without paying them. However, those same developers have very little say in the direction of your product, and any forking of your project would have to compete the economies of scale that come from being a company. The only downside is that you have to worry about being out-scaled by a bigger company, as the developers of ElasticSearch, Redis, Docker, and others found out first-hand.

This is distinct from Free Software, which has different dynamics that are much more friendly to mutual benefit, collaboration, and forking, especially if there's no CLA that pools all of the copyright into one corporate or non-profit entity. But then again, this sort of Free Software moralizing is expressly the reason why Open Source was created as an alternative in the first place. The OSI even used to admit as such on their website:

They don't learn by themselves, but you can add instructions as they make mistakes that are effectively them learning. You have to write code review feedback for juniors, so that s not an appreciable difference.

> Better off training someone off the street to be a software engineer.

And that person is going to quit and you have to start all over again. They also cost at least 100x the price.

That’s wishful thinking. Just because things haven’t changed in the past doesn’t mean it won’t change in the future.

I don’t doubt that the amount of code will not reduce, it’ll just be easier and easier to get AI to fix it.

We are still less than two years into widespread use of this technology, and it’s surprising how good it is.

I am a ‘greybeard’ compiler guy and modern LLMs fix compiler bugs better than me, to a large extent. And it keeps slightly getting better every few weeks.

You aren't the first person I have heard say this. It's an under-appreciated way in which these tools are a game-changer. They are a wonderful gift to those of us prone to RSI, because they're most good at precisely the boilerplate repetitive stuff that tends to cause the most discomfort. I used to feel slightly sick every time I was faced with some big piece of boilerplate I had to hammer out, because of my RSI and also because it just makes me bored. No longer. People worry that these tools will end careers, but (for now at least) I think they can save the careers of more than a few people. A side-effect is I now enjoy programming much more, because I can operate at a level of abstraction where I am actually dealing with novel problems rather than sending my brain to sleep and my wrists to pain hell hammering out curly braces or yaml boilerplate.
