sysidentpy VS zig

Link para o site da documentação: SysIdentPy - SysIdentPy

I'm the only maintainer, but I keep including new features (some exclusives, like the algorithm I've developed in my thesis to create NARMAX models), improving the code and documentation, and fixing bugs.

benchmark codes: Welcome to SysIdentPy’s documentation! — NARMAX models

github: wilsonrljr/sysidentpy: A Python Package For System Identification Using NARMAX Models (github.com)

I built a package where you can build polynomial NARMAX models using the most used method for model selection of this class of models in the beckend. In addition, you can built NARX Neural Networks for forecasting problems (this is built on top of Pytorch) and you can use any model that have a fit/predict method (Catboost, any estimator from sklearn) in a NARX configuration to perform infinity-steps-ahead prediction. Maybe its worth a try. Here is the link of the package: GitHub - wilsonrljr/sysidentpy: A Python Package For System Identification Using NARMAX Models

When writing code in a scripting language, sometimes you need that extra bit of performance (or maybe an async feature from Zig).

NodeJS is by no means a slow runtime, it wouldn’t be so popular if it was. But compared to Bun, it’s slow. Bun was built from the ground up with speed in mind, using both JavascriptCore and Zig. The Bun team spent an enormous amount of time and energy trying to make Bun fast, including lots of profiling, benchmarking, and optimizations.

ntdll.dll!RtlUserThreadStart()

There are valid reasons to use APIs from NTDLL. Where I disagree with zig#1840 is the idea that it is always better to use NTDLL versions of API. Every other software ecosystem uses the standard Win32 APIs and diverging from that without a good reason seems like a good way to have unexpected behavior. One concrete example is most users and programmers expect Windows to redirect some file system paths when running on WOW64. But this is implemented in Kernel32, not ntdll.

Zig also has an IRC channel on libera (#zig) that is moderated by Andrew Kelley.[1]

ESP32 and STM32 support is very welcome!

I have been following https://github.com/ziglang/zig/issues/5467 for a while and progress seemed to have slowed significantly

I have never used it directly, take what I say with a grain of salt.

As far as I know at least part of the idea was to eliminate the function coloring problem by letting the compiler do some nifty compile-time deductions. This had some issues (I don't know if this is still planned, it seems like the kind of thing that should not work in practice). Additionally, there were all sorts of hard technical issues with LLVM, debugging, etc.

I recommend checking the issue tracker, eg. https://github.com/ziglang/zig/issues/6025

I personally don't understand the domain well enough at all, but honestly, I feel like (if possible) Zig should try to double down on its allocator approach.

Instead of trying to use some compile-time deduction magic explicitly pass around an "async runtime/executor" struct which you explicitly have to interact with. Why not?

Yes, fundamentally. In Rust if you take a parameter of generic type T without any bounds, you cannot call anything on it except for things which are defined for all types. If you specify bounds, only things required by the bounds can be called (+ the ones for all types). Another difference is where you get an error when you try pass something which doesn't adhere to a certain trait. In Rust you will get an error at the call site, not at the place of use (except if you don't specify any bounds).

Zig is doing just fine without any trait mechanism and it simplifies the language a lot but it does come up from time to time. The usual solution is to just get type information via @typeInfo and error out if the type is something you're not expecting [0]. Not everybody is happy about it though [1] because, among other things, it makes it more difficult to discover what the required type actually is.
