Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Scriptisto: "Shebang interpreter" that enables writing scripts in compiled langs
Emacs didn't invent REPL, and it's common everywhere. For Rust: https://github.com/evcxr/evcxr/blob/main/evcxr_repl/README.m.... But heck, the compiler is reasonably fast enough that any IDE can REPL by compiling the code.
The value here is more in being able to read a script before you run it, then have it run fast, maybe tweaking something here and there. And a compiled script will run 10,000 times faster than LISP, which can be important.

Go: What We Got Right, What We Got Wrong
https://github.com/evcxr/evcxr can run Rust in a Jupyter notebook. It's not Golang but close enough.

The Hallucinated Rows Incident
The engine uses rust_decimal::Decimal to represent high precision decimal numbers, like the weight property. Serialization of RocksDB keys is done by the storekey crate. To know how Yumi's machine stores diffs, we can now ask- How does storekey serialize rust_decimal? Well, using evcxr to run Rust in Jupyter, the answer is as a null-terminated string:
- TermiC: Terminal C, Interactive C/C++ REPL shell created with BASH
- Exploring Options for Dynamic Code Changes in Rust without Recompilation (hot reloading)
- Go 1.21 will (likely) have a static toolchain on Linux

What’s an actual use case for Rust
In theory you should be able to create Rust notebooks (Jupyter notebook) using evcxr so maybe some AI, data analysis, prototyping make sense if you aim for good performance in final application (protype in evcxr and use notebook as reference to implement final application in Rust for speed and safety).

would you use rust for scripting?
You should check out evcxr
- Nannou – An open-source creative-coding framework for Rust
-
Rust vs. Haskell
There is also implementations of rust REPLs, like the beautifully named evcxr.

The new pdbp (Pdb+) Python debugger!
If you’re already using ipython, this isn’t a problem because you’ll already need to download most of these dependencies anyway. But if you’re not using ipython… you’ll still need to download those dependencies.
-
Pandas 1.5 released
!pip install is error-prone, it is better to use %pip install, ipython even warns about this, https://github.com/ipython/ipython/pull/12954/

Why deprecate loading unpackaged extensions?
The git history (here is the git blame) shows it has not been updated in 9 year. Looks like a documentation issue that you should open an issue against.

Debugging Python programs without an IDE
Do you know IPython? It is a modern Python console that extends the capabilities of the classic builtin Python shell by offering introspection, tab completion, syntaxing coloring, as well as history. If you don't know it, I can't recommend it enough. More information can be found in its GitHub page.
-
External variables in lambda functions in Python
There is an IPython ticket on GitHub on the topic, but it's unclear if the problem has been solved.

No_color
There’s one I’ve come across recently here where you’re fighting against syntax highlighting with extra error context. https://github.com/ipython/ipython/issues/13446#issuecomment...

Django Codebase Reformatted with Black
You can automate setup for developers using this simple script:
https://github.com/ipython/ipython/pull/12091/files
And here’s a GitLab issue requesting support for blame-ignore:
https://gitlab.com/gitlab-org/gitlab/-/issues/31423
I don’t think there’s a corresponding GitHub request, but maybe if GitLab adds this feature GitHub will have some incentive to follow suit.
