Switching one uppercase letter in an otherwise lowercase password adds exactly 1 bit of entropy (per switched letter). On the other hand, any extra lowercase letter will increase the entropy by 4.7 bits (assuming a password on [a-z]). Given

How is this objectively a great feature? This is a spyware that stores screenshots unencrypted (and thus accessible to any other spyware). I am also not convinced that the AI tools would have been offline, thus effectively sharing your whol

I mean you seem to be simply reducing spying to the GPD, when it varies very much with the policies of a country. Israel is 27th by GDP but is a world leader in espionage, and especially in surveillance tools. Similarly France is good enoug

The convertibility between money and gold has stopped in the 70s. Bitcoin allows for instant money transfer, and so does Visa. The fact that bitcoin has no collateral is a whole other topic.

The key point (often missed by these articles) is that aperiodic tilings do not have a (infinite) periodic pattern. This means that you cannot draw a shape on these tiles and say: "the tiling is based on infinite repetitions of this sh

Usually definitions are considered to be finite. Otherwise yes you can just name a number by enumerating its decimals but what's the point. Edit : actually does not even work, courtesy of the Chaitin's numbers

I am not pretending that banks are perfect. But regulations are made so these situations happen as little as possible. In cryptocurrencies, such frauds and gross mismanagement are called an ordinary Monday.

Ah, yes, the freedom to invest all your life savings in obvious unregulated scams such as FTX. Cryptocurrencies advocate for a very libertarian point of view: you are the only responsible of your money, and if you get scammed, sucks to be y

Sure. One example is as follows: each party i generates a random polynomial P_i, and n secret shares of that polynomial (j, P_i(j)) for j in 1..n Then, party i sends (j, P_i(j)) to party j. Party i similarly receives shares (i, P_j(i)) for

A real, complete comparison is impossible as the two systems are fundamentally different and too complicated. What I like with that comparison is remains very simple. If you'd scale BTC to the amount of tx operated by VISA/MC, you

Classical numbers for gCO2/kWh do take into account uranium extraction, and yet despite relying heavily on coal as you point out, nuclear (6-12 gCO2/kWh [1]) still remains one of the most competitive power sources [0]. I agree wit

I clearly despise academics (and the papers they write) who think that everything should look novel by hiding your thought process. Sadly, especially in fields where conferences are favored over journals, this seems to be common: you only h

Probably very few or none of them, cryptography getting broken is common. There is no hint that this weakness was introduced on purpose. Now, did the NSA find the attack on their own, kept it secret and hoped for standardization? One can on

I don't get your point. Cryptography (especially new protocols such as SIKE or anything PQ) must undergo public scrutiny for years or decades, and sometimes get destroyed in the process, that's how it works. Coming up with a usabl

Another funny example is the one of Juno: a whale Sybil-ed the airdrop, and gathered 10% of the tokens. Then, the community voted to strip the whale of most of their tokens. I find the example interesting because it shows that Layer 2 proto

The massive issue I have with these sources is their reliability. Scotland can produce 98% from wind because they can sell the excess or buy when in deficit from their neighbours who modulate their coal/gas plants. If all its neighbour
