If you're happy with NumPy's API, then surely JAX is exactly what you're looking for.

You can't claim to have superior knowledge if you admit you're wrong.

> Once this happens, players will be able to switch between OpenGL rendering and Vulkan rendering

I think this means you'll be able to continue using Minecraft with OpenGL.

What would be the best way to use Vulkan 1.4 in Rust today? Using the C headers with bindgen or writing my own vk.xml generator?

Clip Studio Paint seems very popular for animation. You could also consider Aseprite for pixel art animation.

Really fun! Developing my intuition for a sphere as I played was a nice experience. As other commenters have mentioned, the game ramps up a bit too slowly. Perhaps it would worth adding more than one food item.

One of the reasons I'm really excited about JAX is that I hope it will allow me to write fast Python code without worrying about these details.

People still appear to use Flash these days by downloading an old version and getting a license key from Reddit/YouTube/etc.

Can confirm as someone who was using pre-subscription Office to write/read files while everyone else at work was using the 365 version. Now that I'm using 365 too, I do however appreciate the ability to do shared live editing in the office programs.

New comment by JBits in "When did people favor composition over inheritance?"

If CLU only supported composition, was the Liskov substitution principle still applicable to CLU?

New comment by JBits in "The maths you need to start understanding LLMs"

JBits — Sat, 06 Sep 2025 17:59:29 +0000

For me, it's the very basics of general relativity which made the distinction between the cotangent and tangents space click. Optimisation on Riemannian manifolds might give an opportunity to apply more interesting tensor calculus with a non-trivial metric.

New comment by JBits in "The Little Book of Linear Algebra"

JBits — Wed, 03 Sep 2025 02:24:05 +0000

A good use of linear algebra that I'm working with at the moment is the use of splines as a basis for real (vector) functions. After obtaining the matrix/vector representations you can solve for the spline coefficients (and then plot them).

Linear transforms (such as rotations and displacements) in GPU graphics.

Fourier series in signal processing.

JPEG compression.

Obtaining the best fit element in a vector space of curves given data or other constraints.

Understanding autodiff in JAX.

The mathematical definition of a tensor helps develop intuition for manipulating arrays/tensors in array libraries.

Transition matrices of a Markov chain.

PageRank.

JBits — Wed, 27 Aug 2025 00:22:29 +0000

At least you're working with Rust now.

As someone with zero knowledge of psychology, I'm biased against it. Partly because of my vague impression that psychology tries to fit people to models, rather than viewing models as limited approximations.

For a while I've thought it would be nice to know what results the field of psychology actually has that are trusted. Was there anything at all in the taught content which you liked? I didn't realise the DSM-V was that bad. If research on trans people can be cherry-picked, then does that mean that some reliable research exists?

JBits — Sun, 03 Aug 2025 02:02:30 +0000

My impression about reality is the opposite. The quantum world makes perfect sense while it's the emergence of the classical world which is unfathomable. The crazy "pop into existence" part is still incomprehensible, so I guess it's essentially the same.

New comment by JBits in "Hierarchical Reasoning Model"

JBits — Sun, 27 Jul 2025 20:11:56 +0000

I don't see how that changes anything. By this logic, there's no need for CoT reasoning at all, as a single pass should be sufficient. I don't see how that proves that CoT increases capabilities.

JBits — Sun, 27 Jul 2025 19:31:08 +0000

I would assuming that training a LLM would be unfeasible for a small research lab, so isn't tackling small problems like this unavoidable? Given that current LLMs have clear limitations, I can't think of anything better than developing beter architectures on small test cases, then a company can try scaling it later.

> CoT models can, in principle, solve _any_ complex task.

What is the justification for this? Is there a mathematical proof? To me, CoT seems like a hack to work around the severe limitations of current LLMs.

Some people just like em dashes—myself included. You can find em dashes in articles written by the author before LLMs became a thing.

JBits — Wed, 02 Jul 2025 02:28:15 +0000

The issue is that many of her videos argue that funding for particle physics should instead go into foundations and interpretations of quantum mechanics, specifically research completely identical to what she works on.

This is not helped by the fact that she pushes an interpretation of quantum mechanics viewed as fringe at best. Her takes on modern physics seem typically disingenuous or biased.
