As far as I understand, the latency is improved by the different speed of light of the DNANF: In conventional fibres, it is limited by the refractive index of glass, reducing the speed of light in it to ~70% of speed of light in vaccum (Wikipedia on this topic). In this new concept, the light travels 45% faster.

I think, the lower loss (lower attenuation) is "just" an enabler for long distances: You can easily have hundreds of km without repeaters – and repeaters for DNANF cables would add latency. If they can get attenuation improved a bit more, they may even be able to cross the Atlantic ocean without repeaters.

As a nice side effect, those DNANF cables have very little dispersion, so you can get rid of compensating for that, which will reduce latency too.

As a Fedora user, I thought Debian would be more secure.

What's wrong with your Fedora installation? Mine doesn't do that (also without a TPM chip)

If this is true (or at least plausible to the relevant people), the author of that Twitter post will probably be on the radar of any shady government agency worldwide. Not a nice situation to be in.

Are you sure? Doesn't the "smart edison bulb" design make it harder to dissipate heat to the casing, therefore making the LEDs get hotter compared to PCBs with LEDs surface mounted on them?

Anyway, if you want your ~~light bulbs~~any technology to last long, don't buy the "smart" variant. "Smart" usually means more components and/or more dependencies on interfaces, and more complexity, so a higher chance to fail.

Was ist das Problem?

How about non-native English speakers trying to shame English instead? https://www.youtube.com/watch?v=zJ69ny57pR0

Your comment is incorrect in many different ways.

Butter is fat and some sugar and protein.

No. The butter in my fridge has almost no sugar (0.6g in 100g) and almost no protein (0.7 g in 100g).

Pasta is mostly carbs.

For comparison: The pasta I have at home have more sugar (most have roughly 3g in 100g) and way more protein (12g in 100g).

they all become calories, and if you eat more calories than you burn, they will be stored as fat.

Are you sure you're not simplifying too much?

Also, "just" eating less or more calories is not that easy if you ignore the side-effects. Carbohydrates will make you hungry very soon unless mixed (or eaten after) fibers, fat and protein. Which you should do anyways for health reasons.

TIL my thesis could have been easier if Typst would have been available years earlier.

Lots of places in France are so remote and sparsely populated that public transport does not work there, at least not yet. It may or may not work once autonomous vehicles are fit for rural areas, but this may take a while.

That's another reason for increasing minimum wages, as they try to do.

Actually, 90% income tax for the top incomes was common in western countries in the 50s.
