According to the link, the 1000 number is related to the initial USB mini design with flat sides. It got changed to the kinked sides which we all know and which has... 5000 insertions. Still not a lot, so the argument is the same.

I have also tried the Laptop baking many years ago with an ancient Dell Laptop which was known for its buggy internal Nvidia GPU. However, I have learned in the meantime that lead-free solder requires temperatures much higher than achieved

I don't have didactic examples at hand, but e.g. [1] or [2]. IIRC [1] uses the Laplace operator (second-order spatial derivate) and [2] uses a linear solve inside the forward model through which differentiation is certainly possible bu

Ah, I think I was unclear. I specifically meant your reference to Equinox, because that seemed to me to be somewhat ML specific. In general, I very much agree that "autodiff+autoparallel are really useful for any kind of numerical comp

Yes, but is it really the same? Afaik the `unroll=n` parameter translates `n` iterations into a vanilla `for` loop which is then unrolled into sequential statements (in contrast to a JAX `fori` loop). There still is no loop on the accelerat

A key difference is that each iteration of scan is called by the host. Put differently, JAX can't fuse scan into a single GPU kernel, but launches a kernel for each iteration. Depening on the workload this is no problem. If you have ma

This is still the case afaik. For vanilla "if", the condition must be known at compile time. For runtime, you have to use "cond", "where", or "select" (which may be analogous).

Although not terribly complicated, you can compute fractals like the Mandelbrot set or Julia sets. They look really cool and you can play with visualization.

> You have to hardcode the shape tuples. This is not true. Rather, all shapes have to be known at compile time. That means that output shapes must not depend on input values , but may depend on input shapes -- also explicitely. Furt

Luckily I discovered JAX in the beginning of my PhD four years ago. It has made our data processing (biomedical imaging) so much easier and more readable, albeit with a slight learning curve due to JAX being functional/pure. I am also

Afaik nobody uses MMS in central Europe. Depending on the carrier it is not even supported anymore, and has been very expensive before that. Virtually everyone switched to Whatsapp ten years ago.

We mostly use Whatsapp or Signal, which both use phone numbers for account identification/verification. I am surprised again and again how different the US and Europa are in this respect, and even more about how little people are aware

:D well, _that_ implies iMessage and/or MMS I guess. As I said, nobody in central Europe uses that afaik.

How do you "text a photo"? Does this imply iMessage or MMS? I'm based in Europe and nobody uses SMS or iMessage here, so genuine question.

I have used it many times in different scenarios and networks, including firewall and behind NAT. I never had to do anything manually except copying the passphrase. Did you transfer a very large file?

That's what I was thinking. If we want transparent crypto (i.e. not security by obscurity) and the implementation is highly vetted, its "monopoly" is actually desirable. Of course we might not even be aware of even better met

SIM swapping is one thing, but the actual service (X in this case) allowing access to the account via access to the phone number, even without SMS 2FA enabled, is the real problem.

Thanks for the tip. The map style is very dense but IMHO the best for urban areas. Some names are only rendered in Czech, and hill shading seems to be available only with an active internet connection. I still prefer the shading of "Be
