janalsncm··on Tesla to wind down Cybertruck production
Yes, the crossover point is around $5-10k more than an ice vehicle, assuming the electric vehicle powers a house just as well as a gas generator does.

The cybertruck costs roughly $82k, which is about 40-50k more than other pickup trucks.

For the same price, you could install 2 1000-gallon propane tanks and enough gasoline to power your backup generator for a year nonstop.

I agree that it’s cool, but is it practical? If your goal is to power your house, you can buy a whole-house backup generator for about 1/12th of the cost of a cybertruck.
janalsncm··on I struggle to believe that AI R&D is ingenious
It would have been a lot more informative if the author told us more about what Astra had suggested and why it didn’t work. I have a strong feeling that neither of the first two tasks require an “ingenious” solution. Just applying techniques from similar games. I don’t know enough about the third task to comment.

Instead of asking Astra to do the thing, the author should research similar games and try to apply the techniques used in those games. For example, Scrabble is a hidden information game. Try using an algorithm like CFR which is used to solve such a game.

Similarly, ultimate tictactoe is a perfect information game so it can be handled with MCTS.

Once you understand the basics, you don’t need an “ingenious” solution. It’s a university project.

Convincing a person who doesn’t want a hamburger to buy one is basically mind control and it doesn’t work.

Convincing someone who does want a burger to buy one at Shake Shack does work.

janalsncm··on Baidu released ERNIE 5.5 Flash Base
In 2032 the EU will have an approved version which has been signed off on by 15 different committees.

If you want to fine tune it you will also need to apply for approval from the department of Weight Watchers, which has not been created yet because the naming committee is still in litigation with the American company, and the chair of the naming committee is on vacation for the next 3 months and it is illegal to call him during that time.

janalsncm··on Baidu released ERNIE 5.5 Flash Base
For a large multinational company, probably.

I read the clause as more of a cya from them. I doubt Baidu is going to come after you if you use their model in the EU, but if Brussels has a problem with it Baidu wouldn’t be on the hook.

janalsncm··on Why Clip Art Was Everywhere Until It Wasn't [video]
> There is AI involved, so you can never actually be sure how accurate it is

If you don’t want to watch the full video, how will you know whether the summary is accurate or not?

One option is you could extract the transcript from the video (using AI, since the author-provided transcripts aren’t necessarily accurate) and read it. The technology for this already exists.

> Give it a text box, so I can ask it stuff

This is going to use AI as well.

Awesome. I built a janky version of this for myself but I’m glad it’s supported natively now.

janalsncm··on Why Clip Art Was Everywhere Until It Wasn't [video]
It filled a niche at the time when there weren’t a lot of easily accessible stock images of things. Clip art was the successor to analog “clip books” used for things like ads in newspapers.

Once the internet filled that niche with more and better pictures, shipping a fixed database of images with your software didn’t make sense anymore.

It’s a good video, worth a watch on 1.5x.

The first step to improving something is to show there’s a problem in the first place. For those who believe sidewalks are for people, she has demonstrated that there is a problem.

People got out of crypto after the Mt Gox thing. The ones who stayed accepted the risk.

There is selection bias in play now. The remaining people are naturally more risk tolerant. So I agree this second time around, no lessons will be learned.

janalsncm··on Alleged Chinese spy had 'close relationship' with Nvidia boss Jensen Huang
I agree with everything you said, but all we know is that she had business meetings with him.

The picture in the article has a bunch of other people around them, in a bar/club. Pretty sure he wasn’t laying out the blueprints for the next chip right then and there.

janalsncm··on Alleged Chinese spy had 'close relationship' with Nvidia boss Jensen Huang
A couple of questions after reading this article. The Post is not exactly top notch journalism.

First, does her activity actually fit the definition of “espionage”?

Espionage is the act of secretly gathering confidential, classified, or proprietary information without the owner's permission

The most important question is what she actually sent and how secret it was. Most companies have levels of secrecy ranging from non public to highly sensitive. For example, schematics of their chip would be concerning.

Also, this seems pretty different from setting up a mic behind a TV.

Second, although the article tries very hard to imply there was some kind of infidelity, adding irrelevant details about Jensen’s family, I don’t know that any of that happened.

janalsncm··on Microsoft offers mass buyouts for roughly a quarter of its workforce
Maybe I should’ve been more clear. Your argument above relies on “I’d be shocked if…” which is not evidence in and of itself.

Most American employees are at-will, and the contract in the MSFT lawsuit above was an at-will contract which is why they could be terminated, as you said.

Unless you can provide some other evidence that MSFT employees at not at will, it seems reasonable to believe they are, in which case providing the generous severance they did was not legally required.

janalsncm··on Microsoft offers mass buyouts for roughly a quarter of its workforce
Only a MSFT employee can say for sure what their employment contract is these days, but I found an old court case where they used pretty standard “at will” language.

janalsncm··on Attention Is Not What You Need (2025)
In Qwen 3.5, 75% of the layers are linear attention. I think the theory is that linear attention is usually enough, but some regular attention layers help to handle more sophisticated long-range relationships.
janalsncm··on Show HN: Steal My Bitcoin
The average PHP server that is unpatched now will remain unpatched after OP publishes the exploits because that server’s admin is clearly not scouring the web for security vulnerabilities.

Also, an increasing number of admins of PHP servers probably are no longer alive, so they will not be applying security patches.

Every reason you just gave for not hacking this server is also true for servers which don’t have a $500 prize, which is almost all of them out there.
janalsncm··on Root shell on Samsung TV
> The DMCA in the US and similar anti-circumvention laws around the world (primarily EU) make doing that a serious crime

Yes, this is the main reason why I mentioned the cartoon episode was unrealistic fiction.

I’d imagine a paid service that did this could be illegal. But prosecuting people who did this to their own hardware would be essentially impossible.

Maybe not the same exploit but I found another guy who was also able to debloat his TV: https://github.com/jss8649/quiet-tizen
janalsncm··on Root shell on Samsung TV
There is a Rick and Morty episode where Rick opens up a store that removes the curses from free items the Devil is handing out.

(Surprisingly, the Devil does not consider lawyering up, which is odd because I would expect the Devil to be pretty familiar with lots of lawyers. It’s fiction of course.)

It would be great to use AI to do something analogous with these spy TVs. I would be very interested in stripping the “smart” crap out of my TV to turn it into a kiosk.

janalsncm··on Ask HN: If the models are so good, why doesn't OpenAI just start 100 companies?
For what it’s worth, they are doing that in limited areas. For example the Figma/Claude design controversy.

But you are right, building a business is a lot more than building a product. It’s also a lot more than just name recognition because they have no shortage of that either.

janalsncm··on Ask HN: If the models are so good, why doesn't OpenAI just start 100 companies?
The standard analogy is selling shovels, not hamburgers.

OpenAI is selling people access to a tool to build things. OP is asking why they don’t just build the things themselves, which I believe is a fair question.

janalsncm··on Google staff resign in backlash over its AI contracts with military
The workers don’t seem to be pacifists. They seem to be opposed to some combination of genocide, autonomous weapons, privacy, or the military industrial complex.

Checks and balances on the ability to wage war are not a bad thing, and given the popularity of the US’ most recent entanglement I’d imagine most Americans would prefer more checks, not fewer.

> I guess I don't see how this is news worthy?

At the risk of being overly reductive, a story is newsworthy if the editor decides it is. So one question you could ask is, why did the BBC editor think this was newsworthy?

janalsncm··on Triplet of 'ghostly' galaxies hints at what dark matter is and isn't
Ah, interesting. Maybe it should be called “slippery matter” then.
janalsncm··on Triplet of 'ghostly' galaxies hints at what dark matter is and isn't
I don’t really understand. Dark matter is in most galaxies interacting gravitationally, but not these three. Their idea is that somehow there was a collision event which stripped the galaxies of their dark matter, because the regular matter got tangled up but dark matter somehow didn’t.

But if dark matter is also interacting gravitationally, why wouldn’t it also be tangled up? And is that something we have seen in other collisions ever?
