This couldn't be further from the truth. Linux is a monolith, and famously breaks internal interfaces all the time.

All European Telcos were like this before the EU banned them from doing it. Unfortunately, Switzerland decided not to follow this particular EU regulation.

One of the worst offenders is Obsidian. Users on hn keep praising the UI, but by default the menu text is borderline unreadable under less than ideal lighting conditions.

The economics just don't work out. Small reactors still end up being enormously expensive, but without the huge power output of large ones. There is a reason why all power plants use gigawatt-scale reactors.

You could do that with LTE a decade ago. It is more than fast enough for 4K video streaming, and typical latencies are below 50 ms. Most users would not notice any difference between LTE and 5G.

Maps was yet another gimmick on the first iPhone since it did not have GPS. Other high-end phones at the time had turn-by-turn navigation and offline maps. It is funny to rewatch the original iPhone presentation. It had so few useful featur

I would argue that the first iPhone is in a different device category than its successors. It had only a 2G modem (very slow even in 2007) and (at launch) no third-party app support. It was essentially a dumb phone with a gimmicky interface

Fukushima had three meltdowns (reactors 1-3), and a hydrogen gas explosion that damaged the spent fuel pool of reactor 4. Together with Three Mile Island and Chernobyl, this corresponds to roughly 1% of all commissioned reactors suffering c

It is quite misleading to only focus on deaths due to nuclear accidents. Fukushima may not have (directly) killed anyone, but the cleanup is hideously expensive (estimates say many hundred billion dollars). Containing Chernobyl costed a few

No, coal is barely radioactive at all. The small traces of Thorium and Uranium are completely negligible. An old study from 1978 has estimated that nuclear reactors emit somewhat more radiation than coal power plants, but the levels are ove

Physics articles are even worse. Commenters on HN are mostly science-illiterate but have very strongly held opinions.

Not quite. Geodetic GNSS systems use two different carrier frequencies to measure and correct for atmospheric dispersion. This reduces the error to sub-mm levels. The inaccuracy of real-time GNSS is due to unknown variations of the satellit

There is no reason to believe that this actually worked. There were lots of vaccine candidates in early 2020, and many of them failed to produce a strong enough immune responce. This even happened to big corporations like Sanofi-GSK. The ha

Sunlight contains much more blue light than the output of any LED bulb. This scaremongering about blue content has no scientific backing at all.

GitHub got rid of their banners in 2020: https://github.blog/2020-12-17-no-cookie-for-you/ I believe there is also a lot of "cargo culting" where site admins copy what everyone else is doing without understan

This reminds me of the infamous Cameron Todd Willingham case which also happened in Texas around the same time: https://en.wikipedia.org/wiki/Cameron_Todd_Willingham > During the penalty phase of the trial, a prosec

RF receivers were restricted in some jurisdictions. However, a 30€ SDR stick can receive pretty much any unencrypted voice transmission which makes these rules impossible to enforce.

One principal advantage is that the laser-cooled atoms are unaffected by Johnson noise which sets the ultimate limit in semiconductor (or vacuum tube) based systems. However, their stated sensitivity of -120 dBm/Hz is more than 50 dB a

It looks like a standard atomic physics setup with a vacuum system and a bunch of lasers. Definitely not built to be portable. The performance is quite a bit worse than conventional semiconductor based RF spectrum analyzers which can be car

No, they use a conventional antenna, hence the title "Waveguide-Coupled Rydberg Spectrum Analyzer". The Rydberg atoms essentially serve as an active frequency mixer that produces the difference frequency between the RF input and a

The very low efficiency of e-fuels probably more than outweighs the cost of upgrading the grid. They will be important for sustainable aviation, but anywhere else they don't appear to be economically feasible.

In my experience, USVs can make the uptime worse in Germany. The hardware is likely to fail before the next blackout.

They all rely on ultrasonic sensors and it usually works quite well. I drove a manual transmission VW Golf in 2010 that had it.

I really like the front. It is almost the exact opposite of what BMW has done to their latest range of cars.

I have never had an issue despite living in a large european city. Maybe the reason is that, unlike some people, I don't blindly step into bike lanes.

Satellite internet essentially means that you have to share one cellphone tower with your entire district. I don't see how this can be sustainable for anything but the most rural areas.

In my experience, they are perfectly fine in bike lanes. If your city doesn't have those, that's the problem. Not the scooters.

They are electronically limited to 20 km/h in Paris and weigh no more than a bicycle.

This is plain old whataboutism. The war crimes of the axis don't absolve the allies of theirs.
