Longer explanation: guy behind a company selling PQ algorithms from a new "University" which span up 4 months ago says they're better than everybody else and writes paper about it.

Because you're in an exam, and you cannot really draw a straw. So you have to choose a number randomly, and pretend you chose the short straw if it's a 0. And then hope you're the only one.
The article also discussed how it'll work if you prepare beforehand and actually can draw a straw. Spoiler: you might want to cheat if you chose the short straw :)

Failure is relative - perhaps they decided that there is still some hope.
At least I would switch regularly between "oh, let's give it up" and "no, there is still hope" :)
Perhaps the "sunken cost fallacy"...

Re:Elliptic Curve Cryptography: A Basic Introduction

Point 2 is a simplification that borders on wrong: you don't "wrap around if it's too big" - the point operation will always cross the curve (except for the zero point)!
You "wrap around" because you're using a finite field. As far as I understand, the finite field of the scalars allows you to have an inverse for the multiplication, and the finite field of the points is there to make the calculation easier.

Re:Americans aren't willing to pay to stop climate change
on Thursday July 01, 2021 @03:44PM (#27703677)
In Switzerland there was a vote 2 weeks ago about whether we want to support a law to reduce CO2 output by our population. The law was very clear how the money would be spent: improve heating, direct pay to poor citizens, and many others.
Cost:
- 50 cents per gallon of gas (our gas is about 6$ per gallon)
- 20$ to 100$ for a plane ticket
The law was refused by 51% of Swiss citizen.
What really killed me was that the youngest part of the population, the ones who will be the most impacted by the climate crisis, voted the strongest against it. Switzerland being one of the richest countries, I cannot understand how an increase of 10% on luxury items (plane tickets) can have this impact.
Funny story: now that the law has been refused, the oil companies announced a 15% increase of the gas price... Nobody is protesting so far.

Interesting, but why does the "Check" use a handmade hashing algorithm that is just summing up all bytes?
A much safer implementation would be to take the sha256 of the key and only show the 2 rightmost bytes.

You might be right for single-casual illnesses like a broken leg, CoVid-19, Tuberculosis, and others. But it's a whole other thing when it comes to more complex illnesses.
Having been for 18 months through different types of psychiatrists and clinics, I came out quite surprised in how "trial and error" this whole system is.
I'm writing this from Switzerland, where we have an (arguably) high quality health care system. But the amount of "OK, that didn't work, lets try this other drug". Or, now, 18 months later, "Oh well, we did the list once through. But who tells me that the MD prescribing the first drug did a correct analysis? Lets start the list from top again." Or, for a friend of mine, his girlfriend found a working cure like that: "Oh, this brochure describes your symptoms so clearly, and it's completely different from what you've been treated for these last 20 years. Let's try it!"
Spoiler alert for my case with the list: the top of the list was not better the second time around.
If you think this is cynical, well, I would like at least _one_ of these drugs to work. If you think the MDs are all useless: well, at some times I was glad they were there.
So, well, I think having a little less than random system might be helping. Let the MDs watch if it makes sense, enter the correct diagnosis, and catch the stupid errors data entry people can make. But i'd give it a try...

They did use our permissioned skipchain available on: https://github.com/dedis/cothority and ran some nodes on a server.
Instead of burning 200kWh for one transaction, a voting consensus system is enough.
BTW, there is also an e voting system in that repo, using neff shuffles.

We were working on a more decentralized solution here: https://github.com/dedis/cothority/tree/master/cisc - unfortunately the update is still 1 month away...
This system uses a set of untrusted nodes that form a permissioned blockchain. Updating the chain requires a threshold of keys stored in the first block. The private keys are distributed over laptops/phones.
A person can have multiple devices that accept/deny new keys, while the servers check periodically for updates and can verify the new ssh-keys are legit by verifying the signatures.
