Can someone shed light on these two steps in the approximation? * since cos(x+y) ~ cos(x) - sin(x)*y * ~ cos(x) - x*y, For the first, maybe it's an approximate identity I'd never heard of? F

SongTable won’t compile (on any modern compiler) because the number of initializers (36) doesn’t match the declaration (32)

In addition to the sibling comments, one simple opportunity available to a JIT and not AOT is 100% confidence about the target hardware and its capabilities. For example AOT compilation often has to account for the possibility that the targ

Thanks, those are specific requirements I could definitely see WASM struggling to meet. In my experience in a large+mature enough codebase (particularly one that is already multi-platform, like Postgres appears to be) many of those requirem

The first thing to point out is that our implementation isn't pure WASM. We attempted to compile Postgres for WASM directly from source, but it was more complicated that we anticipated. Crunchy's HN post provided some hints abo

So if I make a new, identical copy of a GPL'ed codebase - should I feel free to use it for whatever purpose I want and ignore the GPL?

The full game isn't playable on that page. I believe all three sets of assets (HLDM, Uplink, Hazard Course) are from demos or free products. Making the full game playable would probably be less OK.

It's totally reasonable to lament duplicated effort, but it's worth pointing out that this particular attempt is from a company[0] whose business is Qt consulting - so it's easy to imagine that they might succeed (due to expe

I think GP is reacting to the word "obligation" (I certainly did.) I'd claim there are actions that may be "morally justifiable" yet not raise to a level that creates a "moral obligation." The word "o

Not GP, but the code in the article passes 'unsigned int mutex' by-value, and then operates on its address (which will potentially be at a different stack address on each invocation, and will certainly be different for different t

Perhaps confusingly, the term "immediate mode GUI" usually describes an API style. NOT an implementation detail. It suggests a particular implementation, but in practice most nontrivial "immediate mode" GUI libraries (in

Variations on the Bridson paper you linked are commonly implemented in games and graphics circles under the name "Curl Noise" - for example Houdini[1] or Unity[2] Google that term for many examples, but [3] looks like a good start

Perhaps, but it's quite convenient for any software that wants to ingest PSD files without the (nigh-intractable) challenge of reimplementing the entirety of Photoshop's parser and rendering systems!

Most* PSD files contain a "preview" copy of the fully-flattened document (which is compressed.) Flat white image compresses far better, so that portion of the file doesn't take as much space. Depending on what your layers loo

Seems to me like you're tacitly agreeing with GP here - you're just making a claim about which currency system you trust more! (And attempting to convince others of the same position.)

Using GP's definition: "custom" engines -- i.e. engines that are not provided commercially by third parties it's pretty easy to argue Fortnite also uses a "custom" engine. (And that's not pedantry - th

Yes! The 010 Editor's templating language is a nearly unique (in my experience) hybrid between C-like declarations and imperative flow that's exactly what I want for parsing arbitrary binary files. The template executes like a scr

I didn't read the parent post as using it that way - I believe they're saying that any claim that "supply chain security" (of videos) will combat deep fakes* isn't necessarily a credible model of security considerin

None of the audio samples play for me (In neither Chrome nor Edge... Other sites play just fine.) Makes it very hard to evaluate claims of codec quality, which seems like the primary purpose of the blog post. :(

A mispredicted branch is incredibly likely to perform operations that would normally fault (consider misprediction of a null pointer check, for example...) I don't think it's feasible to have a (useful) version of speculative exec

By 'optical flow calculations' do you mean a linear extrapolation of the projected 'image-space' position of the ball? If so, that seems like it would be insufficient since a thrown object doesn't move linearly, let
