'tree of arrays' Ahh, that's just Jax's concept of pytrees. It was something that they invented to make it easier (this is how I view it, not complete) to pass complex objects to function but still be able to easily cons

IIRC jax's `scipy.sparse.linalg.bicgstab` does support multiple right hand sides. EDIT: Or rather, all the solvers under jax's `scipy.sparse.linalg` all support multiple right hand sides.

You must be mistaken on the elden ring multiplayer bit, I was not too long ago summoned as a blue phantom when playing on my steam deck.

I'm following the progress of this package, I would not mind a more modern successor to LaTeX. I'm an academic, and I actually do not mind LaTeX. I find actually writing LaTeX to be fairly natural. But every time I come to the pro

Ah, I'd love to try this. But I have a hard cross-platform requirement (Windows/Linux/MacOS) and I can't seem to get this running in WSL. Will keep checking if that improves in the future.

Well, I probably should not have played this, given that I'm (seemingly) in my last year of my PhD. Back to paper writing...

Because I always used to be self-conscious about the typing sounds in-lecture, I used to take hand-notes in class and then immediately after TeX them. While that had the happy accident of reinforcing the class notes, I find that having note

Unless I've misunderstood the comparison, the lists example does not appear to be comparing apples to apples. Reproducing here: $ python -m timeit "list((1, 2, 'a'))" 5000000 loops, best of 5: 53 nsec per loop

Well it plays all ways. PC misses out on the console exclusives, consoles miss out on the PC exclusives, consoles themselves have different exclusives and don't interop. For people getting into gaming when they're young, a big inf

Taking a look at a paper I have that went up this month and another that went up before the dec cutoff on ar5iv, they look 90% OK! Figures with side-by-side plots and algorithm environments are the common culprit for being broken though. Pa

I wish the FEM ecosystem was a little more mature in Julia (particularly weak forms, their derivatives, and assembly). I'm confident about rewriting the other pieces of my research, but it took me a long time to be happy with FEniCS,

Hey, diffrax is cool by the way. I've used it to do some automatically differentiate through some ODEs for optimal experimental design. Great stuff.

My advisor gave me this paper at the beginning of my PhD; useful advice especially when google scholar dumps heaps of papers onto you every so often. Though I'd largely ignore the time estimates. That varies deeply depending on the pap

Both Yahtzee (ZP) and Sebastian (Cold Take), who both ran my favorite two Escapist publications, have resigned along with him. I sincerely hope that the new management at the Escapist actually have a plan here, for the sake of the remaining

It's nice to have easier to use C++ GPU numerical computing libraries, but it seems like there's a good bit of work to go in terms of feature set. Taking CuPy as an example, they've nearly entirely mirrored the enormous featu

Perhaps before killing someone with a comment, you should provide examples to back up your vitriol? The guidelines were reposted a mere four days ago... The writing felt fine to me, if a bit terse.

CUDA being feature complete and having libraries & frameworks optimized and immediately deploy-able for it is all the difference. I don't like much of their business/marketing practices for their gaming GPU division, but their

Yes, to (grossly) summarize the conclusion of the paper: minres can outperform CG on the backwards error ||r_k|| / ||x_k|| whereas CG can outperform minres on the absolute error ||x^* - x_k|| and the energy norm ||x^* - x_k||_A.

The particular pain point of multiprocessing in python for me has been the limitations of the serializer. To that end, multiprocess, the replacement by the dill team, has been useful as a drop in replacement, but I'm still looking for

It's a subjective question. Three that struck me recently were - Cyberpunk 2077 with its new path traced lighting option - Plague Tale Requiem (in general) - The high action sequences and cut-scenes of FFXVI These games have their flaw
