Not all blockchains use proof of work. A better single question would be: do you need a distributed ledger with immutability guarantees (i.e. security against an adversary that might want to tamper with the history of your ledger).

I wonder if the results for "I don't use Rust because..." would change if the answer "It would slow development down too much", or something along the same lines, would be there. At least that's my personal rea

In his comment from yesterday, he wrote that he needed some time. I guess it will be up somewhere next month.

Suppose two students have identical rankings and end up with the same school. If one of them manages to trade (e.g. because they quickly manage to find someone that wants to trade with them), they have an advantage over the other student wh

The article doesn't give me any convincing arguments against UBI. The author uses Saudi Arabia as an example as a country with UBI that works badly. First of all, I have no intimate with if there is any implementation. The author does

Well, when a president convicts someone to a prison sentence because they said the president is a nazi, I'm pretty sure most people would call that corruption (if he bypasses the courts and written laws). I agree not all principles can

This is in a way much worse than if they actually changed their policy. With this precedent, it looks like what they're saying now is "we're not policing content, except for when our CEO feels like it". Basically this is

Your reasoning is flawed (and frankly, phrased slightly annoyingly in your other comments, in a way where you omit your core arguments in what seems like baiting for replies). DNA storage provides durability [1] and information density (per

This is not true at all for most forms of cryptography. Hash functions and symmetric cryptography are just shown to be resistant against all known attacks. For public-key cryptography there are sometimes security reductions to computational

One time pads don't give you message integrity, so it's arguably less secure than most standard cryptography in use today.

If you're gonna go through the trouble of exchanging 1TB of one time key, use a standard one time pad. This method is either insecure (when offsets are not strictly ascending), or unnecessarily wasteful.

If the file gets executed as a script, then __name__ == "__main__", hence L43:53 get executed in the top-level scope, which is also available in the lower levels. This isn't very good writing, since this code will throw excep

No, being fast is good in this case. Password hashing is a different beast, with a different competition: https://password-hashing.net

6 paid weeks off is hardly a sabbatical. For many jobs in the EU you get that many vacation days anyway each year.

Just started using Overleaf as well. It actually has Git support, so if you want to use an offline editor for a while you can just pull changes to your machine, work on it, and then commit/push it to the cloud.

Not really. Shor's algorithm is asymptotically still a lot faster than their new algorithm (polynomial vs exponential), although it might perform slower for primes up to some fixed size. This is generally less important in cryptography

I don't think this is necessarily true? It used to be, but I sometimes see "python" being Python 3 and "python2" being Python 2.

Does IPFS work properly with Tor these days? Last I checked support was experimental at best. Without proper support of an anonymity overlay, using Tor to get around your government's censor doesn't sound like a very wise idea.

Why anyone would start a project exclusively supporting Python 2 six years after the release of Python 3 is beyond me. (GitHub lists the first commit in Nov 2014).

Clever that it uses the client instead of the server! I've dabbled with phone-based authentication via a server-side PAM module before, but you generally don't have full control over the servers you SSH into. Although the question

True. Note that some "post-quantum" key exchange schemes already exist (based on lattice cryptography, for which there are no known poly-time quantum attacks), e.g. https://eprint.iacr.org/2015/1092 . But I h
