This is especially funny since the JR Pass cannot be purchased by residents of Japan.

Hydrogen is not great for airplanes since the extremely low density makes the tanks too large. The best solution would be synthetic hydrocarbons (synthesized using hydrogen) which can outperform fossil jet fuel.

These problems are grossly exaggerated in popular discussions. Hydrogen has been routinely transported and stored in standard steel cylinders for over a century. Most cities originally used coal gas (50% hydrogen by volume) for heating and

This is not quite true. The original gas pipes in most cities were built for "town gas" which was produced from coal and is 50% hydrogen by volume. The infrastructure could handle hydrogen just fine, but the low conversion efficie

The Bohr radius is the result of a simple classical physics calculation (a common exercise for undergraduates in their first year). It depends only on the electron mass and the fine structure constant which is the strength of the electromag

Yes, LLMs have become extremely good at coding (not software engineer though). But try using them for anything original that cannot be adapted from GitHub and Stack Overflow. I haven't seen much improvement at all at such tasks.

IQ tests only work if the participants haven't trained for them. If they do similar tests a few times in a row, scores increase a lot. Current LLMs are hyper-optimized for the particular types of puzzles contained in popular "benc

Companies are optimizing for all the big benchmarks. This is why there is so little correlation between benchmark performance and real world performance now.

That is exactly what I wrote. Gas plants being at 1% implies that there is no cheaper source with available capacity. Why should anyone sell electricity for less then?
72.
by fsh 8mo ago
This is highly misleadling. Nobody is setting the price, it is determined by an open market. This naturally drives it towards the price of the cheapest energy source with available capacity (often natural gas). It would be irrational to sel

The EV-1 was launched with lead-acid batteries and later upgraded to NiMH. It would still not be possible to make a practial BEV with these battery chemistries. The breakthrough came through the microelectronics industry producing billions

Find me a consumer IPv6 router sold in the last ~10 years without a restrictive firewall enabled by default. I have never seen one.

by fsh 9mo ago
If your router had only NAT and someone (i.e. your ISP) sends it a package addressed to somewhere inside your internal IP range, it will happily forward it. A firewall would block it.
79.
by fsh 9mo ago
If you really don't have a stateful v4 firewall, your ISP can happily connect to all of your devices.
80.
by fsh 9mo ago
NAT implementations get broken all the time (NAT slipstreaming attacks). If a manufacturer is incompetent enough not to have a firewall on by default, they are probably also shipping a vulnerable NAT.
81.
by fsh 9mo ago
You seem to have misunderstood how IPv6 works. In a home setup, all the traffic still goes through a single router which typically has a restrictive firewall enabled by default.

Since West Germany considered East Germany to be occupied territory, East Germans had automatic citizenship in the west. This made it uniquely easy to emigrate into the much wealthier country.

Zero. Denmark belongs to the EU and NATO, and Greenland has always had a significant NATO military presence to deter any possible threat.

The nuclear share dropping is a very clear signal about a lack of investment. Shows that nuclear energy is no longer cost competitive, even in a "low regulation" environment.

The app is great, but unfortunately it only works in Switzerland. The same company also developed a german version (DWD WarnWetter, works for all of Europe), and recently a worldwide one (Fluid Meteo).

My impression is that most nutritional research is just p-hacking on extremely noisy data. The only consistent outcome is that eating too much for an extended period of time is extremely unhealthy, regardless of what you are eating. Unfortu

The best silicon single crystals still contain impurities at the 1E-11 level. This project is about doing crystal growing in low gravity (the ultra-high purity is only achieved due to the growth process). The vacuum of space is a lot worse

Tesla is probably the only EV maker with declining sales for the last two years. Quite a feat in a booming market, and remarkable considering that the stock already has a few orders of magnitude of growth priced in.
