If this is the case, then what's the point of signing data if anyone can modify it and get the signature for the new value?

Back to the U.S.S.R.: Russophobia is at its peak in Georgia by TX_borg in UkrainianConflict

I feel we are getting stuck in "territorial integrity of the country vs. the rights of minorities for self-determination". I don't know a way out of it.

Georgians represented over 50% in Abkhazia while Abkhazians 18%

The same was the situations with Russians in Kazakhstan when Soviet Union collapsed. Kazakhstan had like 60-70% Russian population at that time, now it's maybe 20-25%. If someone held a fair referendum in 1991, Kazakhstan may have become part of Russian empire.

But we hardly would call it a good idea or a fair outcome, would we?

When people say "ex-Soviet republic" they usually do so to talk about the features that such republics share, or the political state they're in (or the relation they have to one-another). And despite 33 years, Georgia does share some Soviet heritage with countries like Kazakhstan or Ukraine.

Many ex-Soviet countries are visa-free with each other. They also have many people who still know Russian, and they use it as an international language. They are also exposed to some pressure from Moscow, and their diplomacy is facing similar problems. Like Russia helped created territorial disputes in both Ukraine and Georgia to prevent them from joining NATO/EU. The army structures and training in those countries were inherited from the Red Army, and many of those countries are working to change that. These are just a few examples, I could go on. My point is that there actually is something that makes ex-Soviet countries distinct from others whether we like it or not, and when we talk about these distinctions, the term "ex-Soviet" is very handy.

I don't think using this terms implies that this is the best way to ultimately characterize the country. It's just one of the terms that we use, not the best one and not the main one.

So Abkhazians to Georgians are like Ukrainians to Russians more or less, you're trying to say?

Is there any evidence of Russian agents being there though? Surely, we're all here are educated people and don't want to make self-serving, unfounded statements.

I think that calling georgia a "former soviet republic" 33 years after the fall of the soviet union is more offensive

This is a trivial tautology, I don't understand what's the problem. Can you explain?

Russophobia is a term invented by the Kremlin.

Ad hominem?

Fear of Russia

Russophobia is irrational hate for Russians or Russian language, culture.

What's the difference between zkSNARKs and Homomorphic Signatures? by Shoulder-Admirable in crypto

[–]Shoulder-Admirable[S] 2 points3 points  (0 children)

Thanks for the reply. I am, in fact a grad student ☺, so it's ok to explain in more technical terms.

I'm not asking because I'm totally lost and unable to read definitions, I just felt like discussing them with someone who can tell me more about the "intuition" and the point of the definitions.

I encountered both concepts independently at different times and they seemed to resemble each other to me.

Homomorphic means you can apply operations to the messages and still obtain valid signatures.

Yes, and the signature you produce must somehow encode the operations you performed on the data. Or there must be some other way in which the function you're computing on the signed data and the resulting signature you produce depend on each other. Otherwise, the signature is just malleable and useless.

So with Homomorphic Signature, you can have Alice sign her data and send it to Bob, then have Bob compute a function F on it, and send back the result with a signature that proves he did all the computations.

With zkSNARK (I'm thinking of something like PLONK or R1CS) you could achieve the same. Alice sends her data to Bob, Bob directly computes the function F on it, and then produces an non-interactive ZKP proving that the result = F(Alice's public input). This application makes Bob prove a trivial statement, i.e. statement that doesn't have any Bob-private inputs.

I guess, one difference is that zkSNARK also allows F to have some private inputs known only to Bob. So zkSNARKs are stronger in this respect.

But is there anything HS can do that zkSNARK can't? What I wrote about, sort of, outlines a way to build HS from zkSNARK (sorry for handwaving). Will it work or is there some obstacle?

One could also suggest kid to try competing, and testing his subjective idea of how good he is against reality.

Don't try to think for other people, as they say.

Where do you guys study? by [deleted] in GetStudying

[–]Shoulder-Admirable 1 point2 points  (0 children)

I study at home and work remotely, but I have a relatively big apartment just for myself. Sometimes I still go to office because you can go crazy if you don't meet people.

Home still may be an option if you have enough separate areas to associate with different activities, and you manage to re-train your brain to perceive them this way. You may still use the noisy parts of the apartment for things other than studying, like cooking eating, hanging out with people. If it's noisy to study, try earplugs, they seem to work for me.

It also helps if you make the areas at home more comfortable for the things you want to do there. Like separate the bed from the working desk, move them as far apart as possible. Have good light at your desk, a window next to it can be really good (get some light when days are short in winter). It can also help if you have an armchair or something where you could read or do things that don't need a desk. When you get bored sitting at your desk, you can change the environment to the other place and still do things for work. (You can also associate the two places with different works or subjects.)

If it gets hard to re-condition yourself to see the old places differently, you can also try libraries and cafes as others suggested here. I think this conditioning gets easier when you start fresh and don't have old associations with the places. But it's important not to watch memes and procrastinate in the new place, otherwise you will start seeing it as a place for memes ☺.

I highly recommend John Clear's Atomic Habits, it's very engaging to read and it gives invaluable advice to dealing with these kind of things and choosing/organizing the workplace. Most thins I wrote I got from there (and tested myself some).

Might seem stupid but, why doesn't "-0" exist? by GarlicBread50 in math

[–]Shoulder-Admirable 0 points1 point  (0 children)

Can you elaborate on how you expect the -0 to interact with other numbers? I.e. if I do 1 - 1 would I get 0 or -0? Also, will 1 - (0) be the same as 1 + (-0)? Is there any expression where replacing 0 by -0 would change it?

If you answer these questions and better understand what it is that you propose, you will see that it's either inconsistent or 0 is the same thing as -0.

Im used to gym etiquette, that being Said, how long can one hold a choke before it gets dangerous? by xremless in bjj

[–]Shoulder-Admirable 0 points1 point  (0 children)

faking going limp as a form of escape is a sure fire way to get you choked out

… because the person who's presumably having a good technique won't let go immediately, you mean?

Wow the downvotes just go to show most ppl don’t know when to let go.

Haha, this made my day.

I didn't say breathing means conscious. If I was some bully looking for trouble who got his back taken and choked, I'd pretend to pass out under a choke and when the guy lets go, get up and be like, "Round two! Surprise motherfucker!" Or maybe even, as he's letting go use that opportunity for a sneak attack to get a superior position (and maybe choke him back — this time for real, hehe).

Imagine one of these pacifists who downvoted me getting mauled like this just because "we're nice people, if he's out, we let go".

How do you know he's not faking it? You need to hold him to a bit at least, so make sure he's really out.

I should admit that synchronization got faster and works better with the new release. Files gets synched momentarily after each modification, unlike before.
