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 volume) than kerosene, and is used mostly as a 2nd stage fu

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 work without physical maintenance. One data center sat is li

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

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 of posts and reporting about Anthropic's problems

> 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 their customer base is growing fast.

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 in a good enough condition to be flown again, with low refur

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: https://github.com/anthropics/

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 in Scotland isn't ideal for the efficiency of the

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% fissile, and we're only removing part of the no

>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 were 66% in the last 24h, 46% in the last week, and 42%

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 (24h) renewable generation was 66%, for the last wee

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 indicator, it will show the battery as full until

If you're not sure if there are any important world-writable files, then just check that? On Linux you can do something like "find . -perm /o=w". And you can easily make whole dirs inaccessible to other users (chmod o-x)

How much smaller user base? Looking at some recent data, which may not be accurate (but they're required to publish user numbers in the EU at least), it looks like the user base may be only 0-20% smaller compared to 2022. https:/
