Jax-metal on Apple M-series GPUs is barely useable in my opinion. It's not possible to invert a matrix, for example, because Apple has not implemented the necessary triangular solve operator. It's also not possible to sample point

Not necessarily if you get rid of the energy in another way, right? You could perform hydrolysis to turn water into hydrogen + oxygen, and if you release hydrogen into the atmosphere it will just escape our atmosphere into space.

It's naive to think you can compare vectors without any sort of prior on what this relationship might look like. Hoeffding's D cannot effectively capture relationships between time-shifted series that the (generalised) cross corre

In my experience, PyMC leads to models that are orders of magnitudes slower than equivalent models written in JAGS. Profiling is also extremely tedious, and there is no section in the PyMC docs that touches upon model performance. I really

You might be fine with DisplayLink and two monitors, however in my experience DisplayLink with an M1 and four external monitors was nearly impossible to use because of the input lag. Sometimes the entire DisplayLink driver would crash. I bo

I immediately tried to find a comparison with ARIMA as well and was disappointed. It's difficult to take this paper seriously when they dismiss a forecasting technique from the 70's because of "extensive training times".

Newton's method is an algorithm you can use to minimise/maximise/find the root of a differentiable function very quickly if you start with a reasonable guess. There are many variants on Newton's method, e.g. BFGS that do

This sounds great, but how likely is it that the US will manage to reach 100$/GT?

Statisticians and mathematicians call them dimensions, machine learning engineers call them "features". Statisticians and mathematicians usually interpret observations as vectors in n-dimensional space, which leads to some interes

The minute we have solved AGI, will we have solved economics as well? I would imagine that if you just pit 100,000 smart agents against each other with a virtual currency you could calculate the ideal government policies to maximise welfare

I wish Terraform were less opinionated. It has a very clear set of rules you have to adhere to, and if you try to do anything remotely complex you will encounter barriers left and right. An example is the fact that `for_each` is not support

Not true, the coil emits its own radio waves which are exactly 180 degrees phase shifted with respect to the radio tower. Destructive interference could be measured behind the coil, even when not exactly in its shadow.

Yes, this would work. Hard to reason about LP solvers in complexity notation, but would probably be pretty quick. You could also construct a graph, where every price is a node. Start at 0.00, and do a BFS until you find the desired price. W

This feels like it should be illegal. Just by random chance there will be a point in time where enough tenants ask their deposit back at the same time, and you enter one big economic crisis. Of course, banks also have this risk of a bank ru

Personally, I find that Discord feels extremely bloated compared to almost any other program on my computer. Probably has to do with the fact that Discord has still not released a native ARM version of its client for the Apple M1. Nearly a

Competitive programming is fun and trains quick and accurate problem solving. You can critique the fact that modern programming interviews seem to be too focused on short leetcode problems, but that is an entirely different field than compe

The birthday paradox and the algorithm are not related; the birthday paradox is simply the phenomenon that even though there are several orders of magnitude more hashes than images in ImageNet, it is still likely that collisions exist. The

What role does Akamai Edge DNS play in normal internet traffic? DNS responses usually get cached, as far as I understand correctly. And it is usually possible to change your DNS server to e.g. Google's and circumvent the outage. Does A

If you have $100M worth of carbon captured from the air stored somewhere under the ground, how do you make sure nobody takes advantage of this vast supply of energy? You will have to deal with this problem either way, going straight to the

As a sidenote, does anyone know whether something like an "optimal" Qi charging wattage exist, as in highest efficiency? Power lost due to resistance increases with current squared. Therefore I would imagine charging <5W would

Wondering whether iOS 14.7 also unlocks reverse Qi for other devices, e.g. AirPods. People previously assumed that there was a piece of circuitry missing for reverse charging, but this product disproves that.

I do not understand how hiding private items from the camera breaches your privacy. That is like saying you have already died of thirst because you have to drink water; the preventive measure does not cause the thing it tries to prevent. Fu

You're right! Seems like I skimmed over that part. My point still stands, though.

You could also say Python is pure overhead. You can write any Python programme in C, but more efficiently! C is faster, and therefore better. This article avoids the fact that declarative programming has proven to be more pleasant for most
