You are still ~500 m/s short compared to launching on an equatorial orbit from the equator.

by fsh 11d ago
Launching far off the equator makes it more difficult and is therefore a bigger technological achievement.

Photonic quantum interfaces typically operate at glacial speeds and with terrible fidelities. There is a lot more missing than good qubits.

Electrical engineers in the 1940s already had "infinitely stable" memory in the form of delay lines and Williams tubes. Quantum error correction is incomparably more difficult than using digital bits.

Google is one of many monopolies that are collectively bleeding society dry. Of course, the others should be broken up as well. Waymo is currently financed by a monopolist and has negligible revenue itself, so it is not part of the free mar

Some cute tech projects do not justify a massive monopoly. Google is financing Waymo using the ~300 billion dollar it extracts annually from consumers via ad spending. I would rather pay substantially less on anything I buy, and have the fr

That's probably a lot more than their market share versus Claude Code and Codex.

I'm glad that my 9a has little enough RAM to be spared the worst of Google's on-device LLM features.

Shops used to curate their catalogs by in-house testing products from various suppliers. If a supplier comes up with a better toaster, they can send samples to the most relevant shops and convince them to stock it.

It's not VNC-based, so the performance is much better. It also supports multiple monitors.

Doubles are precise to 1E-16, and the most precisely known fundamental constants have uncertainties on the 1E-12 level. This does not give a comfortable headroom, so the CODATA adjustment that determines the constants from measurements uses

That's not true. Digital movie cameras have a few stops more dynamic range than any analog film or the human eye. Of course this doesn't really matter since analog projectors are astronomically worse than digital on that front. Th

IMHO, the only reasons for using 70 mm IMAX are nostalgia and marketing. Digital movie cameras have far better color reproduction, more dynamic range, zero frame jitter, and plenty of resolution without grain. They are also small and silent

Bohmian mechanics is nonrelativistic, so it has been "falsified" since its inception. It generally makes identical predictions to nonrelativistic quantum mechanics (i.e. the Schrödinger equation), but finding a relativistic versio

I once has the displeasure of using a SoftBank SIM in Japan which relentlessly spammed my phone with unblockable ads. The continuing survival of this company is proof that billionares that got lucky once cannot possibly fail.

With smaller reactors, one needs more of everything: reactor vessels, containment structures, cooling systems, generators, etc. This is why industrial facilities are usually built as large as reasonably possible, and why SMRs fell out of fa

That would poison the entire country. Nuclear waste is many many orders of magnitude more radioactive than coal per energy generated. The meme about coal emitting more radiation comes from a 1970s paper that compared radioactive emissions

Like most industrial sites, large reactors are much more economical than small ones. This is why nobody has built SMRs since the 1950s.

Competing with four free GNSS constellations is an interesting business model for sure...

by fsh 3mo ago
GNSS receivers are passive devices that receive beacons broadcasted from the satellites. It's technically impossible to spy on someone with GNSS.

With nuclear energy, you are dependent on whoever has uranium. This is not a theoretical risk, and already has political and economic consequences for the few countries with a large nuclear energy share [1]. It would be much worse if a sign

The SVP campaign in favor of the initiative was something else. Half the country is plastered with their posters, and social media is full of astroturfing. It didn't pay off this times, but the propaganda dominance of this party is con

I recently had a document break because I used umlauts together with the subfigs package. Apparently both use " characters internally and clash badly. This is not a particularly exotic use case.

The original iPhone was genuinely terrible. A 2006 Nokia could surf the web on the go and tell you where you are. The iPhone could do neither, since Apple did not include a 3G modem or GPS. It also did not have any apps, and one of the key

No, AMD wants to collect some rent from people running Vivado in CI/CD environments.

by fsh 4mo ago
Vivado is an IDE for programming AMD FPGAs. One cannot use it without buying AMD hardware.

The roundtrip time is measured and compensated. Even NTP does this. Knowing the distance is not necessary for time synchronization.

The users are paying plenty of money for AMD FPGAs.
