It's usually kerosene + O2, not H2O2. But H2 + O2 is another classic liquid rocket fuel that has higher specific energy (energy per mass), but lower energy density (energy per volu…

Is a data center satellite really that different from a communications satellite? Starlink sats must have some significant processing power and nontrivial control system, and they …

Taking a 10% stake in a company is far from nationalization. And the big increase in Intel's stock price happened months after that.

You're commenting under an article about politics, not about diabetes research.

NASA mostly runs on SpaceX, so it depends if you consider ISS to be critical. But I wouldn't say it would be mind boggling.

So, your link shows that they probably have like $1 billion in sales per month (but they publicly overstated this by 30%), and that's the struggle to find customers? There are tons…

> a technology that already deeply struggles to find customers As far as I know it's the opposite, Anthropic struggles to satisfy demand, they have tons of paying customers and the…

Starship V2 heat shield was good enough to allow the ship to perform a landing on the ocean in one piece, in a precise spot. But a safe landing is not enough, the ship needs to be …

14.3 seems to come from some Red Hat-specific GCC version, which can be reported as "gcc (GCC) 14.3.1 20250617 (Red Hat 14.3.1-2)". See these random examples I found by googling: h…

Strange that it's not classified as "high", which specifically includes "local root privilege escalations". > High: A significant problem, typically exploitable for nearly all user…

You're not contradicting my comment, I was talking specifically about the key with full permissions that the LLM found (the article doesn't talk about other keys that LLM could hav…

> what they thought was a narrowly scoped API token, and they very clearly state that they never would have given an AI full access if they realized it had the ability to do stuff …

It sounds like the keys just don't have any scoping. From the post: > The Railway CLI token I created to add and remove custom domains had the same volumeDelete permission as a tok…

Not exactly, it was a normal solar panel business started by Elon's cousins (SolarCity), but it wasn't going well, and in the end it was bought by Tesla for much bigger money than …

Well, I only said that if we're considering a ~fully renewable energy generation in the UK, with supply evened out by massive pumped storage projects, then locating all the storage…

600km is roughly the distance from the hilly parts of Scotland to the south of England.

If you're talking about uranium enrichment, that's like saying we increased the amount of gasoline on earth (by refining crude oil). Natural uranium is ~99% non-fissile, and ~1% fi…

> Isn't pumped hydro severely limited by geography in many places? Scotland seems to be a perfect place for pumped storage. I see that UK has 4 pumped storage stations, 2 in Wales,…

>England is 90% renewables The thing is, it's nowhere near 90% in general. 90% is the generation right now, with sunlight and good wind. On the site you can see that renewables wer…

The title may be misleading, but IMO not for the reasons you mentioned. "90%" is based on generation right now, live. On the site from the post you can see that for the last day (2…

IMO putting an important number in your post/comment, and not providing a source for that number, is also kind of low effort. If you verified the number before writing, you already…

That's cool, thanks for the links.

I haven't used them, but IIRC they maintain a constant voltage until they're discharged, when it instantly drops to 0. That may be a problem, because if your device has any battery…
