Godel's incompleteness is not that complicated. The main insight Godel had was that proofs as well as provable statements can be encoded in numbers. This is obvious to everyone rea…

An attack is a reason to believe that you can solve the problem. I have no idea how'd I go about solving P=NP, but I did have some thoughts on provable security against transient e…

You're trying to come up with a homemade ORAM. All I'll say is that this problem is harder than it seems.

Websockets are subject to the same origin policy. There's nothing you can do to violate the SOP via websockets that you wouldn't be able to do with regular HTTP or XHR.

Your point about the need to "popularize" zk-snarks etc. is well-taken and I upvoted you for it. But that said, we seem to be talking past each other at this point. I don't see why…

When I clicked the link, I figured this would be a research paper from MIT. It took me a bit of reading to figure out it was just a student project report. That's why I posted the …

This is not a peer-reviewed research paper. It seems to be a project report likely done by undergraduates. The paper is full of typos and it is not clear what the specific novelty …

> In the real number field, additive inverse of a positive real number is indeed the negative of that number. The negative of that number is also obtained by the application of una…

You are wrong in several ways. 1. You literally cannot prove this fact from the Peano axioms because Peano arithmetic operates on natural numbers, not integers. 2. As I said in my …

My point is that you cannot prove something that is true by definition. The OP trying to prove that the product of two negative numbers is positive is like asking to prove that 0 +…

This is not a proof of why the product of negative numbers is positive. The reason why the product of negative numbers is positive is that we define multiplication to be that way. …

Yeah, many red states have made it illegal to strike. And of course, this eliminates any possible leverage that employees have over employers to force better treatment and that is …

The main argument is that NIMBYs are outnumbered at the state level. They "win" at the local level because older, richer homeowners are overrepresented at community meetings.

HN doesn't allow edits after a few hours.

Sorry I had a typo. I meant to say very little of the content is in English. But the page title is in English and that matters because I can google for "Jagran UP budget" to get to…

Some people on the website are complaining that people are putting their video titles in English but the content is in some other language. This is not a lame attempt to get more c…

I actually think it's not as bad as some make it out to be, provided grants are funded at a reasonable rate. What's changed over the last couple of decades or so is that funding ra…

This is practical advice, but it also points to the reality of scientific funding today -- you can only get money to do things that you already know how to do. You must have an ide…

Three points are worth making here. Nobody lives in the Sahara, the population centers in Africa are in the tropical regions and the Mediterranean. Africa will be the only continen…

This will likely change once Africa becomes the most populous continent, which is expected to happen somewhere around 2100.

The answer is because the script evolved and was not designed so letters appear in somewhat random order. Brahmi, which is the parent script for most Indian scripts as well as a bu…

Swiggy is a scam! They stole 200 bucks from me (as food wastage charges) because I didn't look at my phone for 15 minutes after I placed an order with a full address that I had alr…

Not too long ago, my official title was postdoctoral scholar and I was at UC Berkeley. A little while before that, I was a PhD student working with a couple of "postdocs" whose tit…

I feel both sides are making reasonable points. On the one hand, telling people where they ought to buy their food from does seem like government overreach. On the other hand, ther…

Thought-provoking article. I got over my obsession with emulating others' success when I realized that a lot of supposedly successful people were successful primarily because they …
