    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 solv…

    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 atmosphe…

    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…

    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 …

    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 la…

    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'…

    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 varian…

    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 i…

    Wonder if this can be used to bypass ImmersedVR's display limitations

    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…

    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 …

    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…

    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. Sta…

    It blows my mind that there are people who manage to find exploit chains like these, amazing job!

    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 econom…

    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 …

    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 …

    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…

    As a sidenote, these SVG graphs are absolutely beautiful. The flow diagram is even responsive on mobile!

    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 se…

    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 …

    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…

    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 …
