This is not bidirectional. The Davis-Putnam-Robinson-Matiyasevich theorem shows we can make a Diophantine equation that acts as a universal Turing machine, but there’s Diophantine equations that cannot be solved by Turing machines: https:&

It actually took only 9 months to work around, and the new method is actually quite effective. After fixing some early bugs it’s as effective as the original drill technique.

Mars 2020 has a microphone. You can probably find audio out there but here’s some: https://science.nasa.gov/mission/mars-2020-perseverance/soun...

So yeah topological sorting is one element, but that global stack is a data race! You need to test set inclusion AND insert into it in an ordered way. Global mutex is gross. To do so lock-free could maybe be done with a lock free concurrent

Very cool! Just wanna point out that Mirror + Rotate is really just 3 different mirrors. Of course it may be more interesting to try to characterize the visual domains in terms of those 3 mirrors rather than trying to do so obfuscated betwe

I am a huge fan of the work towards putting this in kanren as λKanren: https://www.proquest.com/openview/2a5f2e00e8df7ea3f1fd3e8619... A few of my own experiments in this time with unification over the binders as varia

It’s also funny because it’s a small, incomplete, incompatible subset of c++… seems like a perfect LLVM / clang rewriter case too, it would be easy to convert and be pure c++. Hell even a clang plugin to put the compile time into one p

It’s exactly the same to try to use pixel buds on an Apple phone too. I don’t blame Apple or Google so much as the ridiculous pissing matches of a society that refuses to find ways to cooperate efficiently. So much energy is wasted in the n

No one is really mentioning this article in from a highschooler. Awesome job! I'm happy to read this today and really hope she will continue to see such inspiring stories and maybe some day make some.

Is there any succinct publication of his observations?

That's the only part I care about dang. I still use WSL1 and have done a number of interesting hacks to cross the ABI and tunnel windows into "Linux" userspace and I'd like to make that easier/more direct

Definitely out of date, e.g. the 3SUM subquadratic conjecture (probably 11) has been solved and improved on [1]. If it's not been already there's immediate application, e.g. problem 41. [1]: https://link.springer.com&#x2

There's a book that's explicitly about this, "Program = Proof", and though it's not beginner and needs maybe a light version for earlier learners, is an excellent example.

I've really had a pet peeve about footnotes on mobile and this does the crime. If you click a footnote and it jumps very far away and doesn't have a return navigation, I have left your page usually after the second time I see a fo

I liked the way Pearl phrased it originally. A calculus of anti-correlations implies causation. That makes the nature of the analysis clear and doesn't set of the classic minds alarm bells.

Yeah I work in an FFRDC, pushing the frontier of our exploration of space. I'm quite passionate both about the employer and (most of the time) my work. If I didn't care about my employer at that level I woulda been out the door af

and probably no where to hide if you want to just rest and vest. "Rest and vest". What a luxury. Some of us are trying to tread water with an anvil chained to the waist. That's what I get for choosing to work for something I&

I think one of the reasons I have that example is that specific dynamic is cited in most planetary science texts as "de-coupled", "invariant", etc etc, when in fact it's the major casual influence here, which was qu

The Mars global dust storm is caused by coupling of angular momentum of the (solar) system, a global a effect. The Mars system itself down to the dust does not create sufficient conditions

The idea of computing as the shared stage to reflect our own intelligence is really what sticks out to me as the best way to frame what interacting with a computer means. It's not new but Alan did a great job of motivating and framing

As someone who knows not enough people care about the math, please ignore this advise and actually learn the math. You might come up with a better representation in the process. In any case you'll learn more than just it works, but how

Yes! I am much more productive in those hours too despite being "a morning person" with regards to getting up early and being spry. On my own hobby work I find myself crushed by hitting flow at like 1 am, finally, and then oh crap

TTY queries are written to stdout but read from stdin. That's not user interaction. E.g. if you're system doesn't have ioctl for window size (or you're over a remote serial etc), setting the cursor to the bottom right an

I may be biased as I am a trained Mathematician, but I always feel when someone says "Math is Hard", that is because they had bad teachers. Math is easy if you build up from fundamentals, not like physics education where you say &

There are still bit flipping tricks like rowhammer for RAM, I wouldn't be surprised if there are such vulnerabilities in some CPUs.

Programming in dependent types with univalence (Homotopy Type Theory) is an awesome way to see this realized. The typing statement has to be proven by realizing the isomorphism demanded by substitution. You are more than anything directly p
