I agree, but also via some napkin math, the chance of getting those different results is something like 40%. (Ie, if you sample the same signal twice for the numbers they did in the study, there’s a 40% chance it’ll be >0.04 away from th

Has anyone here actually read the paper? Heavily clickbait headline, completely exaggerating the study results, which themselves are not very rigorous (to be generous) Tiny sample size - 36 people completed Numeracy has R^2 = .27 Language h

Thats an awesome setup and very similar to the one I have. But damn triple-digit-ms does actually sound shockingly slow for what is effectively just heavy text processing. Is there a huge amount of text?

I’ve got a personal project compiler I built and it’s hit by this very hard. Testing involves (naturally) generating lots of executables. Running it in a Linux docker container takes around ~1s for all 500 tests. macOS by default takes arou

Excellent time to mention rust's `ControlFlow` enum which allows doing this exact sort of thing https://doc.rust-lang.org/std/ops/enum.ControlFlow.html Not as ergonomic as a direct tree-iterator, but I can&#x

I don't think is apple/google. This sounds like the kind of thing small companies do. I would be very surprised if that was FAANG I am not a fan of leetcode interviews myself, but I don't think the FAANG process is that bad.

I can't tell if this is joke but will assume not. It's because the .net version is needed for some reason. There are not processors that run .net bytecode, primarily because they would be slower and worse (and again, don't ex

Is this referring to homebrew? On the one hand i get it, but on the other hand reversing a binary tree isn’t some crazy leetcode grind. Most people can figure it out in a few mins and i think its fair to reject someone who can’t

The tl;dr (I spent lots of time investigating this) is that it just fundamentally isn’t a good bytecode for execution. It’s designed to be small on disk, not hardware friendly

I don't think it is an argument in favour of it. arith-mean = E[x] , the first moment of x geo-mean = exp(E[log x]) , so log geo-mean = first moment of log x They are both equivalent in amount of information preserved, but arithmetic p

Absolutely. Point is we have to judge it in context. People saying horrible things for no reason on a message board is fundamentally different to causing a stampede in a cinema. I agree that we need laws to make "yelling fire and causi

Try the helix tutor itself. Install, then do `hx --tutor` (binary is also called helix rather than hx on a few package managers).

Lots of vim/emacs mentions so I feel obliged to mention Helix ( https://helix-editor.com/ ). Used neovim for _years_, tried Helix for a few weeks and never looked back

Can you elaborate on this? My understanding is you can specifically and formally define the natural numbers with addition and multiplication, although multiplication means the language is no longer decidable. You can define natural numbers

Yes, this is correct. The span itself - the (ptr, len) pair - is on stack (by default) but the data is almost always on the heap, with stackalloc being the most notable exception

`b line` and `expr expr` both work fine in lldb. I agree the ergonomics are less excellent, but that doesn't seem a reason to completely abandon lldb/gdb to me. Maybe I am missing something

Avoiding conflicts of interest is key, but lacking interests is worse imo. Having someone with experience in the role has value and I generally think his AI policy is excellent

AI safety shouldn’t stymie the obvious value of AI, but the claim that AI safety is utterly irrelevant seems just as counterproductive as claiming we need to stop all AI research right now
