Whenever I discover something I think I "should" do, I ask myself two questions:

• Do I need to do it?
• Do I want to do it?

My goals are to complete my work on Leo and to continue doing fun computer projects.

Yes. I set a timer to remind myself to take a break.

> Btw, do you have any ideas for balancing your family life, bad emotions, limited time, etc.

My only advice is to recognize that family matters more than anything.

Thank you, EKR.

> Goals

Some people say that societal changes are happening too quickly, and there's a need to rapidly acquire new skills.

However, some things are not that easy, which causes a lot of anxiety. What is your perspective on this issue?

Maybe Edward can talk about how to evaluate Rust thing with Leo :-)

I'm not sure what you mean.  Issue #3662 suggests rewriting Leo's beautifier (aka Orange) in rust. I expect a speedup of about 100x.  This is worth doing because my present beautify scripts only beautify changed files.

It's also worth doing because I want to learn rust :-)

I'll be applying the central lessons of info issue #3730:

- The way to learn a new computer language is to dive right in after doing just a little study.

- Expect to put 10 in for every one out at first. That's ten units of effort for every unit of results.

In other words, confident learners don't expect everything to be easy at first!

Ray Wang said, "Some people say that societal changes are happening too quickly, and there's a need to rapidly acquire new skills."

I mean, after so many years, so many languages, so many new technologies, why are you interested in Rust alone? (Rust corresponds to what he says about new skills, )

We're not trying to understand the benefits of the Rust language, but how you choose it.

Maybe it's just taste :-)

I'm interested in Rust because:

- It's important to the future of python.

- Transliterating leoAst.py to Rust will make Leo's beautify commands about 100x faster.

I'm interested in other languages and technologies besides Rust, but speeding up Leo's beautifier seemed like a good next thing to do.

Thanks for your "last" lesson, despite with you interactions after that post you keep teaching us in the community.

Regarding Rust and the oxidation of everything (A.K.A. rewrite it in Rust) I have found Nim[1] a pretty good language with visible inspirations on Python (like its syntax) and without over complications of Rust or Zig, for example the borrow checker (but Nim's garbage collector can be disabled).

[1] https://nim-lang.org/

I have rewritten some Pharo code in Nim for efficiency purposes or make some interop between both, because I need functionality available in Nim but not in Pharo.

Maybe you or other Leonistas would find Nim interesting, in their explorations of other technologies.

Cheers,

Offray

Thanks for the link.

I am converting leoAst.py to Rust because the RustPython project has already done the hard work of converting Python's parser and tokenizer module to Rust. This project has 363 contributors!

As I'm not making migrations for Python, Nim and now Julia are calling my attention for specific projects/prototypes. But yes, it seems a pretty good project for such migrations and yes, with a lot of heavy lifting already done.

I'm plowing through the interactive rust manual and the actual RustPython code. It's a slog.

Rust has the C world's wretched syntax and complexity. nim has Python's simplicity and clarity.

So yes, I would use nim if I could.

I've just glanced at nim code.  "I" instead of "if"?? Lowercase is much easier to type!

Never mind. nim's intro page clearly shows python-like keywords.

I thought I was reading nim code at https://rosettacode.org/wiki, but I must have been reading something else :-)

Looks like Nim can use a good range of scientific computing libraries, and there are some GUI libraries.  So at this point the two compiled languages that would be if serious interest to me would be Nim and Julia.

[Offray Vladimir Luna Cárdenas]

Also I recently discovered Julia's Pluto[1][1a] and I really like their focused notebook environment saved in plain text instead of Jupyter's cumbersome and human unfriendly JSON. A breath of fresh air, following the steps in human/diff friendly formats for interactive notebooks of Pharo's Grafoscopio, Elixir's LiveBook or Clojure's Clerk.

I don't know about Nim's scientific ecosystem (Julia seems better in that regard). But one of the advantage of novice's mind is that we can start without the heaviness and even ignore the one related with popularity of fashion (like the one in Rust these days).

That Pluto really whets my appetite!
