In most civilized countries the law is "innocent until proven guilty" - and if I (and the vast majority of people) are innocent, why the fuck is tracking a thing?

And a deflationary nature is known to cause bubbles.

I mean centuries of inflationary monetary policy also caused bubbles, sooo...

God I wish more artists would support direct donations. Yoink the file from wherever and in exchange sneak 10 bucks into the artists pockets.

Which breakthrough do you mean? Can you rephrase your question?

The signal does not care about how it gets from the sender to the receiver. The only thing that matters is that at the receivers end 0s and 1s can be separated. One common measurement is the eye pattern. If the eye is "open" enough (=matches the spec), communication is possible.

Impedance mismatch causes reflections (visible as oscillation after rising/falling edge), differential pair line mismatch degrades the slop of the signal transition (rising/falling edge). Geometric features only matter if they are large compared to the signal wavelength. As a rule of thumb features smaller then 1/20th of a wavelength can be safely ignored, often times a ratio as large as 1/5 works just fine. USB3 uses 2.5Ghz (5Gbit/s) or 5Ghz (10Gbit/s), where 1/20th result in 3.4mm and 1.7mm respectively (assuming an effective dialectic of 3.17). This is still grossly simplified, because in many real systems you don't control the entire transmission line (eg. user buys a random cable and expects it to work), so it makes sense that the USB consortium specifies eye patterns and factors in various system uncertainties.

RAM on the other hand uses 16/32/64/128 single ended data lines, with a dedicated clock line. Data does not have to arrive perfectly at the same time, but the margin may be as little as 1/10th of a clock cycle. Here accurate length matching is absolutely required. Its also the reason why the same CPU + RAM combination may archive higher stable clock rates on some mainboards then on others.

USB3 is quite forgiving regarding the layout. The standard +-10% impedance matching is fine, and because there is no dedicated clock line you don't need to do length matching either. Even differential pair length mismatch is not that big of a deal. If 0.1mm is easy to archive, sure go for it, but I'd rather compromise on this in favor of more important parameters.

I don't want to rent the battery in my car.

That is why.

NFTs require arbitrary data storage, which not all blockchains support (or are prohibitively expensive).

Undoubtedly the best naming scheme. The x2 suffix should not be dropped tho, because it shows that USB and the alt-DP mode can be used at the same time.

Droidify is the best! Best performance and UI of all compatible clients, and even handles 3rd repos that wont load on others.
