SymPy VS dmca

Thank you for your interest. There are some interesting examples in the SWE-bench-lite benchmark which are resolved by AutoCodeRover:

- From sympy: https://github.com/sympy/sympy/issues/13643. AutoCodeRover's patch for it: https://github.com/nus-apr/auto-code-rover/blob/main/results...

- Another one from scikit-learn: https://github.com/scikit-learn/scikit-learn/issues/13070. AutoCodeRover's patch (https://github.com/nus-apr/auto-code-rover/blob/main/results...) modified a few lines below (compared to the developer patch) and wrote a different comment.

There are more examples in the results directory (https://github.com/nus-apr/auto-code-rover/tree/main/results).

That's interesting. You should consider yourself lucky to have met Wolfram employees, as they are obviously vastly outnumbered by users of Mathematica.

I have not met any developers for either of these products but I know that SymPy has a huge list of contributors for a project of its size. See: https://github.com/sympy/sympy/blob/master/AUTHORS

You may not be hearing about SymPy users because SymPy is not a monolithic product. It is a library. If you know mathematicians big into using Python, they are probably aware of SymPy as it is the main attraction when it comes to symbolic computation in Python.

https://github.com/sympy/sympy/issues/9479 suggests that multivariate inequalities are still unsolved in SymPy, though it looks like https://github.com/sympy/sympy/pull/21687 was merged in August. This probably isn't yet implemented in C++ in SymForce yet?

Sympytorch:

> Turn SymPy expressions into PyTorch Modules.

> SymPy floats (optionally) become trainable parameters. SymPy symbols are inputs to the Module.

sympy2jax https://github.com/MilesCranmer/sympy2jax :

> Turn SymPy expressions into parametrized, differentiable, vectorizable, JAX functions.

> All SymPy floats become trainable input parameters. SymPy symbols become columns of a passed matrix.

Look at sympy.isprime for a carefully-optimized pure-Python solution (though if gmpy2 is installed, which it usually is, it will use that instead after trying the easiest cases)

Every DMCA takedown notice in https://github.com/github/dmca is a net win for git as a decentralized version control system, especially for repositories that require signed commits. Unfortunately, some people upload only a snapshot of their repository working directory instead of... using git like it is supposed to be used I guess?

I’m with you thus far, but I’m trying to parse the notice to see why GitHub is even complying (see https://github.com/github/dmca/blob/master/2024/03/2024-03-1... ) and I think Torrentfreak got it wrong. I think they’re trying to claim infringement on Plex Server, but the English in the takedown notice is barely legible (and it feels like a mixup between trademarks and copyright), to the point that I find GitHub’s compliance odd.

Text of tweet thread:

Hello everyone. We have some unfortunate news to share with you.

Today, we received a DMCA takedown from Valve on all our public GitHub repositories and all its forks made by the community.

https://github.com/github/dmca/blob/master/2024/01/2024-01-1...

While we were discussing the project's future internally recently, we already came to the conclusion to stop the development of the project due to the current state of the code being unusable anymore with s&box's recent major engine changes, and that we overall moved on from it.

Sadly, this means this DMCA takedown is the nail in the coffin. We cannot bring it back and we've hit Valve's attention, it seems like they definitely don't want us to use their IP (which is totally fair and legal from them).

> Is there anything that average folk can do against these notices when they're sent to companies like GitHub?

They can file a counter-notice, commit to accepting service of process if the other party wants to sue, and wait 10-14 days. There's a guide at https://docs.github.com/en/site-policy/content-removal-polic... and there are plenty of example counter-notices in the https://github.com/github/dmca repo.

From the posted notice[1], they answered "No" to the question "Do you claim to have any technological measures in place to control access to your copyrighted content? Please see our Complaints about Anti-Circumvention Technology if you are unsure." Is that the same thing you are referencing?

I don't know why you're arguing with me when I'm literally giving you sources backing up that what I'm saying is a mere statement of fact: contracts are inherently subject to copyright law like any other text, although the individual violation may be hard to demonstrate and cases difficult to win.

If I understand your example correctly, you would take an existing SaaS's ToS (i.e. copy their copyrighted work), publish it as your own (i.e. lie) and then file a DMCA takedown request (i.e. commit perjury) to force them to remove their ToS? Yes, you could do that. But since you likely can't demonstrate that you're the original copyright holder (e.g. trivially their SaaS pre-dates your service and they probably have internal documents like e-mails surrounding the drafting of the ToS whereas you don't unless you forge those as well) and sending a DMCA takedown request for works you don't actually own is literally a felony crime, I don't think that's a winning strategy.

To be clear: yes, there are laws against abusing DMCA takedown requests, precisely because otherwise anyone could just send them out for fun. Specifically DMCA takedown requests include a statement under penalty of perjury from the copyright holder that they hold the copyright. So this isn't a special DMCA law but just a boring old felony crime involved in fraudulently filing illegitimate legal claims.

If you're wondering why you've never heard of this it's probably because you're thinking of sites like YouTube which don't actually receive DMCA takedown requests normally but instead provide an arbitration system to allow content owners to avoid messy legal back-and-forths over the back of Google and instead be trusted based on who they are (i.e. smaller creators will be stuck in appeals limbo trying to talk to a human whereas large corporations will usually be trusted by default). This does not however apply to e.g. GitHub, which is why there is a public collection of DMCA takedown requests hosted by them: https://github.com/github/dmca

To speed up this conversation: if you can think of another example where your conclusion is "but this is dumb" then it's likely because your example is, not the legal situation you're looking at. Also "but this is dumb" is not a counter-argument to "this is what the law is like". The law does not care if you think it is dumb and saying it is dumb is not a good defense if you end up in court.
