I have the feeling that social media adoption can be very volatile - that makes me hope that something decentralized and healthier could take over soon.

Maybe one catch on Flashes: it's not open-source, is it?

Regarding Bluesky-based Flashes, there is an ongoing GoFundMe campaign, but it's been there for 7 months and hasn't reached its 40k goal. Regardless of the funding goal, aren't there enough people interested in this to make i

I think that's indeed one of the main problems, although I think people don't care because they don't understand what are the risks that directly concern them. A valid question would be at what point (if ever, and I want to b

I very much agree. I think that one of the fundamental things that would make it easier for a healthier way forward would be the ability to more easily move from one platform to the other, hence reducing inertia-induced monopoly. Bluesky&#x

It’s worrying how much control platforms like Meta have over what people see. Their moderation and ranking systems often act as invisible filters—shadowbanning, or quietly removing reach without transparency. This kind of centralization mak

Pretty cool! nimblas in particular is what I was looking for. Will move to matrix if I have any other question ;)

Thanks for the answer! What I would find very useful is an API that allows one to call directly BLAS/LAPACK routines. Is that possible in SciNim? If not, how difficult would it be to write the necessary wrappers? I had a quick look at

Pretty cool. Would love to use Nim for scientific computing, but I am not sure how mature are, e.g., Neo ( https://github.com/andreaferretti/neo ) and alike. Any positive feedback?

hmm I tend to be a bit skeptical about "ipse dixit"-like statements, but I think I got your point about compilers/transpilers :)

by zanellia 5y ago
Pretty cool! How do you manage multiple target languages with a single AST parser? Do you use an intermediate AST?

by zanellia 5y ago
Interfacing existing C code would be an important thing to be addressed. It is currently a missing feature, unfortunately.

I agree that error handling is one of the main things to be improved. The problem is that in some cases the AST walker ends up in unhandled states and prometeo throws a generic exception with a line number only. Are you looking at something

Anyway, the main point is to give it a name that is as informative as possible. If I read "transpiler" I immediately make the connection with the fact that it translates a high-level language into another high-level language (whic

If you have a better reference I'd be happy to change my mind.

Pretty cool! I should check how it works in more detail.

by zanellia 5y ago
No, that's not the timescale of interest, I would say. However, if the big chunk of computations is delegated to HPC libraries I would say that NumPy could be rather competitive there (although still not easy to embed). If instead you

Right, MATLAB Coder is a very related tool.

I did look into Nim, but, given Python's maturity/popularity, I decided to stick with it as host language for the DSL.

by zanellia 5y ago
Good point, it should be easy to add Julia to the Fibonacci benchmark. Here is the Python code https://github.com/zanellia/prometeo/blob/master/examples/fi...
22.
by zanellia 5y ago
I though about using Nim as a host language for the DSL for a while, but then decided to rely on Python simply because it is more mature (and I had already partially figured out how to manipulate Python ASTs to generate C code).
23.
by zanellia 5y ago
It generates a Python extension, doesn't it? Would not know how to run it outside of Python.
24.
by zanellia 5y ago
Right, for sure I would not need to re-invent the machinery to translate a class into a glorified C struct. The whole thing started with C in mind for portability arguments, but it might be a good idea to keep an eye on C++ as an option.

Intrinsics (or directly assembly) are used in BLASFEO ( https://github.com/giaf/blasfeo ) the linear package used by prometeo. It would be cool to generate assembly directly for a few things, but that would require quite

It's not so easy deploy an algorithm written in Julia on an embedded platform though, is it?

by zanellia 5y ago
Thanks for the question! My background is in numerical optimization for optimal control. Projects like this https://github.com/acados/acados motivated the development of prometeo. It's mostly about solving optimiz

by zanellia 5y ago
Not sure what a "superoptimizer" would look like in this context. For a reference, I know for sure that this https://github.com/giaf/blasfeo (which beats Intel MKL) was coded entirely by hand.
29.
by zanellia 5y ago
hmm not sure, the compiled LLVM code would still depend on the runtime library?
30.
by zanellia 5y ago
if we are arguing that implementing a numerical algorithm in C is as easy as implementing it in Python - I would disagree. But maybe I am just wrong :)
