While `uv` works amazingly well I think a lot of people don't realize that installing packages through conda (or let's say the conda-forge ecosystem) has technical advantages compared to wheels/pypi. When you install the nump

While the limit of increasingly concentrated Gaussian's does result in a Dirac delta, but it is not the only way the Dirac delta comes about and is probably not the correct way to think about it in the context of signal processing. Whe

Observation assimilation is a huge field in and of itself. Observables have biases that have to be included in assimilation, they also have finite resolution and so observation operators need to be taken into account.

Similarly I switched to Colemak, and I agree, it's not worth it for most people. I switched because I never typed with proper technique in QWERTY. I would only use ~2 fingers on my right hand. I tried multiple times to retrain myself b

I wasn't worried about safe usage, more that some of the initialization may be moved inside the benchmarking function instead of outside of it like intended. I'm sure you know more about it than me though.

Related on the Eigen benchmarking, I see a lot of use of auto in the benchmarks. Eigen does not recommend using it like this ( https://eigen.tuxfamily.org/dox/TopicPitfalls.html ) because the template expressions can be

These benchmarks look to be ~8 years old, and don't really agree with benchmarks done by other sources ( https://romanpoya.medium.com/a-look-at-the-performance-of-ex... , https://eigen.tuxfamily.org/index

It seems like every large project these days has coalesced around Eigen, what are some of the advantages that Blaze has over Eigen?

I agree, I think upper bound constraints go against what is commonly accepted and used in the Python ecosystem. What I try to do on my projects now is to always have a nightly CI test step, in theory if an updated package breaks my package

There have been lots of posts here about efforts to “modernize” Fortran, which is great! But I’m wondering what the current state of things is. Has anyone recently started a new project using modern Fortran and can comment on their decision

There’s a lot more to it than just snappiness. But where I think Microsoft is going to have a tough time is ensuring x86 compatibility as well as Rosetta does.

The short answer is to measure methane you rely on methane absorption features. To do that you need to be looking at a source through the methane plume, from a satellite this source is the ground. From a ground instrument you can use the s

From a user point of view Python packaging has probably never been better, but it is still a huge mess from anyone having to maintain these projects which might explain some of the dichotomy in the comments. In my experience most of these p

A lot of package managers that distribute binaries (e.g. conda-forge) rely on CentOS 7 because of the relatively old glibc version available, I wonder what all of these projects are planning on moving on to

Base Fortran has a lot of advantages for scientific programming over other languages, but I think there are two factors that are contributing to it's unpopularity: 1. Models are increasingly becoming much larger projects where flexibil

I was starting to get wrist pain in my right hand at the end of the day. I believed it was from never learning to type properly, I only used two fingers on my right hand even though I could type relatively fast. I tried many times to re-tra

I have found that there can be huge quality differences between cheap and more expensive LED bulbs as well. Specifically the ones that use a cheap rectifier. Sometimes I think that I can see them flickering out of the corner of my eye.

It would be interesting to see some example questions and answers. Since the test is multiple choice is it possible that the model has gotten very good at estimating how likely a possible answer is?

Annualized over the last 6 months inflation is now under the 2% target. I would be surprised if we see anything more than a quarter-point at the next meeting.

While not a completely open experience, Microsoft does let you do a lot more on the newer consoles, e.g. https://www.howtogeek.com/703443/how-to-put-your-xbox-series...

This should be correct but it probably is less about the "animation being closer to real life" and more about the actual measurement method. A camera measuring at 24 fps is likely going to have exposure times closer to 1/24

We bundle DLLs in our wheels in such a way that it "just works" for the user but it kind of feels like a hack. First a main DLL library is built completely separately from the wheel. Then a binary wheel is built where the .pyd f

In terms of numerical computing I don't think this is going to be a battle of core language speed, Python has already lost here. The question is going to be what are the advantages of a language designed with a focus on number crunchin

I have had this happen a few times too. I have found the best way to minimize this is to install nothing in the base environment except for conda and make sure you use a different environment for everything else.
