theemathason Show HN: PyApp – runtime installer for Python applications

theemathason Did I receive fraudulent DMCA takedowns?

Sorry for the irrelevant reply, but I'm trying to get some attention on this.

This youtuber got a fraudulent DMCA notice, and his counter-notice got automatically rejected. The person who sent the notice isn't associated with the devs, and is asking for a $100 ransom to get the channel reinstated. How could this be fixed?

Proof that the person sending the notice isn't "authorized on behalf of the copyright holder": https://twitter.com/Lionheart/status/1671349063931838464

Tweet about the automatic rejection of the counter-notice: https://twitter.com/Azrial_Vanity/status/1671696220190810113

Tweet about the initial DMCA takedown: https://twitter.com/Azrial_Vanity/status/1671323777978736643

Mention of the $100 ransom: https://twitter.com/Azrial_Vanity/status/1671332970836140032

Any youtube people on here can help? Or anyone else have any advice?

theemathason A growing number of scientists are convinced the future influences the past

Reversing time on an attracting force still gives you an attractive force. Velocity is reversed, but acceleration isn't.

Imagine a ball being thrown up and then falling down, in a parabola. Reversing a video of that still gives you a video of a ball in a normal parabola trajectory.

theemathason The Point of the Banach-Tarski Theorem

> All real numbers, and all numbers of any other variety, can be written with a finite number of symbols.

This is false. In some sense, there exist numbers that can't be referred to. We can refer to the set of real numbers as a whole, but not some of the elements. https://en.wikipedia.org/wiki/Definable_real_number

But then there are issues with defining "definable numbers", which complicates things by a lot. https://mathoverflow.net/questions/44102/is-the-analysis-as-...

theemathason The Point of the Banach-Tarski Theorem

An alternative formulation of the axiom of choice: The cartesian product of a collection of non-empty sets is non-empty.

theemathason The Point of the Banach-Tarski Theorem

The main reason that we use real numbers is because we need real numbers to do calculus, at least in the normal way. And to do physics, we need to do calculus. You can keep approximating integrals as sums of very large number of terms, but it gets unwieldy to handle symbolically.

theemathason Character.ai (chatbot) drama due to censorship

Previous discussion on HN about the website: https://news.ycombinator.com/item?id=33020694

For the last few days, there seem to be a lot of new users discovering the website, due to word of it spreading within the vtuber community, and a Washington Post article.

Currently, the website has been down for almost an entire day now. I assume the devs are trying to figure out how to deal with this.

The devs apparently wrote a statement which then got deleted from some reason (TLDR: They say some of the issues were unintended side effects of changes made to handle the increase in users, and the devs are trying to fix the issues. There's also a separate set of issues that were side effects from a change intended to censor NSFW stuff.) https://www.reddit.com/r/CharacterAI/comments/y03ncu/newsupd...

Some users are extremely angry, and their discord got so bad that they had to (justifiably) shut down it completely (hopefully temporarily). And I've heard of harassment and even suicide threats (Can't find the source though).

theemathason Stable Diffusion based image compression

Here's a similar case of a scanner using a traditional compression algorithm. It has a bug in the compression algorithm, which made it replace a number in the scanned image with a different number.

theemathason Researchers achieve ‘absurdly fast’ algorithm for network flow

The o(1) here represents a decreasing function in m, such as 1/m. (Note: This is little o, not big o.)

Therefore, for any k > 1: m^(1+o(1)) grows more slowly than m^k but faster than m

theemathason Rust's type system is Turing-complete (2017)

Systems which are turing-complete but not turing-equivalent are stronger than turing machines. See: https://en.wikipedia.org/wiki/Hypercomputation

The "All known Turing-complete systems are Turing-equivalent, which adds support to the Church–Turing thesis." thing seems to have an implied "Turing-complete systems that are physically implementable." (I edited the article to add that.)

The parent comment is talking about solving differential equations. That's a very different thing from computing differentials. Automatic differentiation doesn't help with differential equations at all.

https://en.wikipedia.org/wiki/Chess_notation

See the "chess notation examples" table. The password doesn't match any chess notation, but it's close enough that it's obviously (to me) intended to be a chess move. In particular, it moves the pawn in front of the queen (in the initial position) forwards two spaces.

theemathason SQL queries don't start with SELECT

In my undergrad class, I was thought that the order is "FWGHOS" (pronounced, "fwog hose"), i.e., FROM, WHERE, GROUP BY, HAVING, ORDER BY, SELECT. (LIMIT was omitted from this.)

This acronym has "ORDER BY" happen before "SELECT", but this article have them the other way around. Does this difference ever matter?
