To set the record straight for the above comment - - it's true that there isn't a precise frequency needed for microwave ovens to heat food - however, "polarity flipping" is just a description of electromagnetic radiatio

Another interesting little go difference (along with other newer languages like rust, but not c/c++/c#/java/javascript) is making equality lower precedence than bitwise operators, so that var & 1 == 0 tests the lo

Uh, I guess this got combined with the thread on https://twitter.com/DimitrisPapail/status/166684395282416846... . The original result is legit, this GPT tweet has a number of issues

I posted a reply, but I think ultimately this is just a coincidence. There's a naïve reason that "mov S P" looks redundant ("just use S instead of P later"), but in typical GPT fashion, this is specious, and can&#x2

Can be a fun linktree alternative at the very least. Spent way too long making https://rooms.xyz/pzf/noclip , the physics engine they expose has some unfortunate limitations but there's enough to have fun with.

I had trouble with that too initially. I think that's actually fine: the representation the paper wants to use is that the variables in a path are the ones set to true, so omitting one means that variable must be false to satisfy the e

The conversion to DNF is fine. The original clauses map directly to pairs of new clauses, so fixing an assignment to the original variables V you can always satisfy the same number of the DNF clauses. You can do worse by choosing the wrong

Unsurprisingly, there's nothing here. Most of the paper describes a brute force search across all possible variable assignments in the form of a graph (with some pointless polynomial improvements like making it a trie), where you build

Sorry, I should have been clearer, totally agree about the podcast being a poorer source on the reality and history, and just not trustworthy on the big picture. The article you shared is a fantastic resource, but I would think better of it

That definitely comes through in the piece the parent linked, it's very much a narrative of fighting against misinformed outsiders pushing phonics for various research-based reasons, instead of just trusting teachers.

I'd dispute your characterization of the NEPC summary as well-reasoned. It's definitely a different perspective, but it's clear in a preference for valuing the experience and beliefs of "literacy scholars" over any

I would have much preferred if the author spent more time giving an objective assessment of what ChatGPT had actually accomplished at each step. The "Labyrinth Sudoku" description feels like a classic language model speciousness.

The author's lack of mathematical literacy is pretty striking. I don't mean not realizing it was a log ratio, but presenting the raw percentage-to-pixel expression as if it were meaningful. Clearly the constant term and overall sc

One aspect of the solution which I haven't seen touched on is that this is a problem for which a straightforward greedy approach works. I know when I do competitive programming, "will greedy work?" is usually the first questi

Indeed, this article is embarrassingly wrong. Not sure how anyone could write > The letter I [...] would be referred to with the phrase I per se, I, which means in Latin "I by itself (is the word) I." It's the letter I, no

The concept is great, there are a handful of limitations that become more apparent with actual use. The main one is there is no encoding, just decoding. The generated code and representation of the parsed data also sometimes feel idiomatic

As others have pointed out, a generalization of this method (iterated function systems) can generate a large class of fractals. There's a some fun software for generating these ( see https://en.wikipedia.org/wiki/

I'm hoping to have the FFX particle system (mostly) implemented soon, which will make a big difference. If you join the discord, I'd be happy to help give you some help with that process. Compression algorithms themselves are ofte

One thing I didn't see mentioned in the article is the motivation for choosing the particular (exponential) mapping. If you imagine replacing your function with f(s)=1-1/g(s) for some g with g(0)=1 which goes to infinity as s does

I think a lot of this confusion stems from the author framing this project in a way that is, frankly, nonsense. Vanishing points have nothing to do with the clipping plane, and 3D computer graphics isn't trying to approximate the coord

You can scroll the letter bank. It all shows up in landscape for me, but that obscures the grid.

Could you elaborate more on interpolation and weirdness of composing quaternions? I thought a big selling point for quaternions was the ease and naturalness of just using slerp, whereas with euler angles a similar approach gives bad results
