I’m sure they’ve gotten more than one hot wallet from out of work crypto bros. Probably a profitable venture.

Realistically, ships should tip over if you turn you broadside into the wind with full sails.

Beam reach is typically ideal, and the keel will keep the ship from overturning

These ships seem a little too bottom-heavy though. The animations could imply more ”physics” happening by tilting the ship a little at times.

Forced, presumably, by the student themself.

In the mobile app, it’s under Settings -> Manage history

Not that hard to guess, right? ;)


oooh, i wouldn't dream of installing the app, i use browser only

It does for me too, in Safari on iPhone.


What is ”SV” in this context? Silicon Valley? (Not a US resident, and I’ve never heard of any software cooperatives from there.)


Yes, SV=Silicon Valley. Startups aren't co-ops (the term "co-op" implies employee governance for example). But employee compensation is heavily loaded towards equity or stock in the employing firm. If you're an early hire at a unicorn, you can make serious money off your ownership share in the company. It helps align the incentives of the employees and management. Press coverage of Silicon Valley doesn't usually mention it, but employee ownership is a huge part of the culture.


It’s effective against teenagers maybe. Not so much against Amazon, Meta or wherever botnet/crawler is coming out of China these days from up-and-coming AI companies.


Then block all of Amazon, Meta, or wherever botnet/crawling traffic is coming from that doesn't honor robots.txt, sends DDoS reflection traffic, submits SMTP messages (in large volumes, not just probing) for domains they're not authorized for with SPF, or whatever else applies to the protocol you're using

If they can't keep their ranges clean to a reasonable degree, their customers will need to move if they want to access your part of the internet. New sign-ups will always be hard, so some amount of abuse is expected, but if it's the same abuse traffic for weeks after you've notified them, well, it stops being your problem at some point


See the other comments in this thread. The perpetrators are unknown and are jumping between residential IPs. Possibly botnets?


Then see my other replies in the thread where I've specifically addressed residential IPs, e.g.: https://news.ycombinator.com/item?id=48163060


This is the post I’m talking about. Make sure you understand how it would not be productive to go after each ISP individually when the traffic is from all of them.

I mean you could block entire AS numbers that relate to amazon or big tech datacenters


wouldn't help, much of the traffic we've observed look closer to ddos patterns - IPs from all over the world, many different networks, each IP makes one request only, doesn't come back. highly distributed, no form of blocking would be effective except maybe captcha or proof of work.


How to make hydrogen production cheaper and easier: include an atomic reactor component.

Huh?

I’d be interested in hearing about some scenario where this actually costs less, given the cost of building anything nuclear in 2026.


I agree, the experience building nuclear reactors is mixed bag. Some builds failed, like Flamanville 3, Hinkley Point C, Vogtle 3. Some builds succeeded: Barakah nuclear power plant, Fuqing 5,6. It really depends on maturity of supply line and political support.


The real question is: how do we produce hydrogen from the coming massive overbuilding of cheap-but-variable solar. Nuclear reactors are a whole different animal: even if we build them "cheaply" they're not going to approach the costs of overbuilt solar, so those nuclear watts will be better used for other purposes.


Coupling PV to electrolyzers and efficient hydrogen production using solar energy is still open research problem. Batteries will be probably needed.

"The low efficiency of PV-electrolyzer systems can be attributed to several factors: intrinsic losses in both the PV and electrolyzer units, energy consumption by balance-of-system components (e.g., inverters, thermal management), and, most critically, ineffective electrical coupling. Although some researchers advocate for direct coupling as a cost-effective solution, variable solar input remains a major challenge. Fluctuations in solar irradiance can cause the power delivered to fall outside the acceptable operating range of electrolyzers, leading to frequent shut-downs and start-ups. These cycling events can accelerate degradation, particularly in PEM electrolyzers, and also affect the purity and yield of hydrogen"

"Recent studies also highlight the integration of battery energy storage systems (BESS) into large-scale PV-CSP hybrid plants as a strategic enhancement. With anticipated declines in battery costs, this integrated approach may become increasingly viable in the near future."

This site seems to auto-translate itself into my browser’s locale. Interesting approach but probably not the right choice if your audience is the tech crowd. I’m perfectly fluent in English, thank you very much.

I suppose it’s a clue that the whole thing was copy-edited or written using LLM. Not reading it.


Well, you’re saying that after you already learned how to do it.


I am very new to the crafts and I can attest trying to solder smd stuff, with correct equipment is way easier than soldering 2 wires correctly together. And I also kinda hate QFN like packages where you can’t see the pads.
