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.

Beginning Python: Project Management With PDM
PDM is a solution that allows for easy creation and management of python projects. Some of the key features that will improve the management of python projects include:
-
A question about good practice when using docker.
You'd need a proper dependencies management tool like PDM or Poetry to exhaustively resolve and lock down all the transitive dependencies if you want to have anything closed to reproducible build.
-
pdm-dotenv: Simplify Your Project's Environment Variable Management
Are you working on a Python project that uses pdm for dependency management and dotenv for local environment variable and secrets management? Do you find it frustrating when CLI tools like pgcli don't automatically pick up your .env file, forcing you to resort to npm install -g dotenv-cli? I've got a more convenient solution for you!
-
PEP 582 rejected - consensus among the community needed
I first learned about PDM from a blog post written by one of the PDM contributers. The post was about OOPifying argparse to allow for easy creation/modification of subcommands that exist as their own classes/files, and to avoid maintaining a single long script with an endless number of subparser.add_argument(...) lines.
It's per project, check out pdm if you want a preview https://github.com/pdm-project/pdm

PEP 704 – Require virtual environments by default for package installers
That's more or less what PEP 582 plans to do, but it's been stalled and mired in discussions for years. The PDM tool went ahead and implemented it though if you want to use it: https://github.com/pdm-project/pdm

Boring Python: Code Quality
I'm liking PDM for a while now. Quicker than Poetry and built according to the Python package spec in mind and not as an afterthought. While it was originally meant to work with PEP 582, it works with virtual environments too (now default).

Nim v2.0 Released
Ones that have not been mentioned so far:
nlvm is an unofficial LLVM backend: https://github.com/arnetheduck/nlvm
npeg lets you write PEGs inline in almost normal PEG notation: https://github.com/zevv/npeg
futhark provides for much more automatic C interop: https://github.com/PMunch/futhark
nimpy allows calling Python code from Nim and vice versa: https://github.com/yglukhov/nimpy
questionable provides a lot of syntax sugar surrounding Option/Result types: https://github.com/codex-storage/questionable
ratel is a framework for embedded programming: https://github.com/PMunch/ratel
cps allows arbitrary procedure rewriting to continuation passing style: https://github.com/nim-works/cps
chronos is an alternative async/await backend: https://github.com/status-im/nim-chronos
zero-functional fixes some inefficiencies when chaining list operations: https://github.com/zero-functional/zero-functional
owlkettle is a declarative macro-oriented library for GTK: https://github.com/can-lehmann/owlkettle
A longer list can be found at https://github.com/ringabout/awesome-nim.
That looks interesting. Unfortunately it looks like it hasn't been updated in a while? Is that because it's complete or a lack of interest?
For example, the approach mentioned at the bottom of the README of integrating via nlvm (https://github.com/arnetheduck/nlvm) sounded great but appears to be unpursued.

The counter-intuitive rise of Python in scientific computing (2020)
Nim actually has LLVM support via nlvm

It's not officially blessed, but it does work.

Is Nim a Transpiler?
I mean, to me it is a transpiler because it is a "frontend" to several other languages.
You choose whether you want to emit C, C++, or JS. There's an experimental, fledgling community LLVM frontend for Nim, that is what I would call a "compiler":
https://github.com/arnetheduck/nlvm
What Jetbrains calls Kotlin -> JavaScript, is "transpilation"
What Google calls Java -> JavaScript in j2cl, is "transpilation"
But this is all pedantic IMO.

Nim Version 1.6 Released
Being able to compile to C, C++, ObjC, and JavaScript natively (and LLVM using https://github.com/arnetheduck/nlvm ), along with an excellent FFI (including to and from Python) means you don't need to rewrite dependencies as you can use them directly. Nim is great at glue code - arguably better than Python.
Along with general language characteristics such as being high level and productive like Python, but with intricate "bare metal" control when you want it, really does make it suitable for writing almost everything.
