Don't confuse launch _price_ with launch _cost_. It's been estimated the internal F9 launch costs are around $15M-$20M. The $5M is a marginal cost-target for fully reusable Starship.

Well, divide et impera. Fairly straightforward for AI inference (not training): The existing Starlink constellation: 3491 V1 sats × 22.68 m² = 79176 m² 5856 V2-mini sats × 104.96 m² = 614 646 m² Total: 0.7 km² of PERC Mono cells with 23% e

Ideally, in an organization this should be a centrally pushed group policy defining CIDRs. Like, at home, I have 10/8 and public IPv6 addresses.

Yeah, I had to create a user on many language versions just to keep the old skin. I fail to see a point in wasting 2/3 of my screen estate to whitespace.

NTR is a very inefficient use of nuclear fuel. What you want is a NSWR: https://en.wikipedia.org/wiki/Nuclear_salt-water_rocket A true nuclear rocket. Just like a chemical rocket is a controlled explosion, NSWR is a co

Sun wanted to do the same thing in late 90ties - picoJAVA (embedded), microJava and UltraJava (VLIW workstations). Relegated to the dustbin of history.

Impulse Labs, a startup, is doing lithium-backed kitchen stoves. Claims to heat-up 1L of water in ~40secs. That's at least 8.6kW. https://twitter.com/sdamico/status/1592553611879673856?s=20

The 400V is between phases. 230V is between a phase and ground. Ie, you get 3 wires (phases) of 230V from the 400V connection. Btw, Europe standardized at 230/400V in the nineties. In Czechia we switched from 220V to 230V in 1993. Not

>That's where we're at: Just randomly select some parameters until the data fits, and lo and behold, it fits. When I read that it felt like a Monte-Carlo simulation. A legit approach in modeling. And indeed - the link to the p
