As the document I linked to says, Jax autograd supports custom data types and custom gradients. It’s honestly exhausting arguing with all you Julia boosters. You can down vote me t…

Try reading the docs before making sweeping negative comments about what a piece of software can and cannot do. https://jax.readthedocs.io/en/latest/notebooks/autodiff_cook...

It is true that Jax cannot differentiate through C code. But it can differentiate through python code that was written to accept Numpy.

For Jax I believe this is false. Jax is composable. In fact it’s a core design goal. Jax arrays implement the Numpy API. I routinely drop Jax arrays into other python libraries des…

How does Jax lose composability or introspection?

Lengthy, nuanced discussion about benchmarking between Turing devs and Stan devs.

The right benchmark is Stan https://github.com/TuringLang/TuringExamples/pull/25

When I look at google trends or redmonk rankings, Julia appears stable, not accelerating.

Why minizinc instead of Google OR? Seems like Google OR best minizinc at their own contest? https://www.minizinc.org/challenge2020/results2020.html Is it more customizable? Or expr…

Thanks Viral. To be clear, I’m a python user who’s cheering for Julia, because I live the problems of python and do see the potential of Julia as a better path. But unfortunately I…

> 2. I don't entirely follow this point. Perhaps using PyArrow's parser would be faster than what is timed here, but is that what the typical Python data science user would do? I a…

@Sukera Fair, but, if I break up all the loops and if statements into functions, those functions still have “end”s

That was mostly meant as a joke, thus the “;-)” I don’t really care much about syntax choices, but my small complaint about “end” is that it takes up a line which reduces the amoun…

Thanks. I watched the JuliaCon state of Julia presentation. As I wrote in my original post, I appreciate the investments the Julia core developers are making, that have improved bu…

Preach, brother. I’m cautiously optimistic that JAX (or something like JAX) can save the python programming language from stagnation by essentially building a feature-complete reim…

Let me second GP’s sentiment. I find Julia really slow for my purposes. I don’t know his reasoning, but I will explain mine. None of this is surprising and is oft discussed. Julia …

FWIW I agree with you. I’ve always found cython easier than Numba. And more performant. I think Numba has a lot of potential and will improve as they fill out remaining language co…

In the uncommon event I need to write a loop from scratch, and I need it to be really fast, I just rewrite that one jupyter cell in cython or numba. But that is a small piece of my…

Honest question from a heavy python user who would switch if it made sense: Are there any comprehensive benchmarks that show Julia outperforming Pandas or PyTorch or SciKit? Obviou…

I’m fascinated by Julia and have test driven it before but it didn’t click for me. Maybe I was doing it wrong and/or the ecosystem has matured since I last looked. I guess I genera…

Thanks for the pointers, those crates seem great. The flaky multithreading libs are my least favorite part of python, and rust’s strength in this area seems very appealing.

I deal with a lot of ragged data that is hard to vectorize, and currently write cython kernels when the inner loops take too long. Sounds like Rust might be faster than cython? Tha…

I am in similar boat. Python centric data scientist. Very tempted to try to learn Rust so I can accelerate certain ETL tasks. Question for Rust experts: On what ETL tasks would you…

Worth keeping in mind the principal agent problem literature. Selling equity in a company is vulnerable to “lemon” problems. Startups with product market fit want to minimize dilut…
