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.

How Head Works in Git
Here's a great walk through for how Git works from the bottom up: https://jwiegley.github.io/git-from-the-bottom-up/
It's short, easy to understand and you'll understand HEAD.

git-appraise – Distributed Code Review for Git
Very tangential:
Gerrit also stores some of its configs in a git repo. I was setting up a new instance, but couldn't get Admin permissions because the way my auth front-end didn't play well with the docker image's assumptions.
Gerrit already does a lot of its work via non-standard references. For example, you don't push to a branch, `refs/branches/foo`, you push to a separate `refs/for/foo` namespace that creates the review.
Similarly, Group config is stored in the All-Users git repo [1], but in references created after a UUID, in `refs/groups/UU/UUID`.
I ended up having a to exercise the plumbiest of plumbing commands [2] to create a new commit from scratch (from a tree, from the index, from blobs), to update the group ref to add myself to the Administrators group (this, of course, requires a local shell and permissions on the Gerrit host). It was a great way to exercise what I had learned in Git from the Bottom Up [3]

Books for learning Git
I found Git from the Bottom Up helpful. It is very short as well. Then refer to the official book when you want more detail.
- Good git course and/or where to practice real life scenarios?

the first time i had to deal with a huge git rebase conflict
I recently came across "Git from the Bottom Up by John Wiegley" (thanks to Coding Blocks podcast), he has a chapter about rebasing: https://jwiegley.github.io/git-from-the-bottom-up/1-Repository/7-branching-and-the-power-of-rebase.html

Git-SIM: Visually simulate Git operations in your own repos with a single termi
You won't have to put your entire life on break in order to understand the fundamentals of git and why it works the way it works. Going through https://jwiegley.github.io/git-from-the-bottom-up/ and really understanding the material will take you a couple of hours at max, but will save you a lot of time in the future.
Wanting to understand things before using them is hardly elitism, not sure why you would think that.
Just like you probably don't want to fix bugs without understand the cause, it's hard to use a tool correctly unless you know how the tool works.

Understanding Dependencies in Programming
Dependency Management in Other Languages: We've discussed Python and Node.js in this article, but dependency management is a universal concept in programming. Exploring how you handle dependencies in other languages like Java, C#, or Rust could be beneficial. (I think Rust's cargo is an excellent example of a package manager.)

Scriptisto: "Shebang interpreter" that enables writing scripts in compiled langs
Nice hack! Would it have been possible back then to use cargo to pull in some dependencies?

Making Rust binaries smaller by default
Yes, I am sure this is going to be a part of Rust 1.77.0 and it will release on 21st March. I say that because of the tag in the PR (https://github.com/rust-lang/cargo/pull/13257#event-11505613...).
I'm no expert on Rust compiler development, but my understanding is that all code that is merged into master is available on nightly. If they're not behind a feature flag (this one isn't), they'll be available in a full release within 12 weeks of being merged. Larger features that need a lot more testing remain behind feature flags. Once they are merged into master, they remain on nightly until they're sufficiently tested. The multi-threaded frontend (https://blog.rust-lang.org/2023/11/09/parallel-rustc.html) is an example of such a feature. It'll remain nightly only for several months.
Again, I'm not an expert. This is based on what I've observed of Rust development.

You can't do that because I hate you
The author provides very surface-level criticism of two Rust tools, but they don't look into why those choices were made.
With about five minutes of my time, I found out:
wrap_comments was introduced in 2019 [0]. There are bugs in the implementation (it breaks Markdown tables), so the option hasn't been marked as stable. Progress on the issue has been spotty.
--no-merge-sources is not trivial to re-implement [1]. The author has already explained why the flag no longer works -- Cargo integrated the command, but not all of the flags. This commit [2] explains why this functionality was removed in the first place.
Rust is open source, so the author of this blog post could improve the state of the software they care about by championing these issues. The --no-merge-sources error message even encourages you to open an issue, presumably so that the authors of Cargo can gauge the importance of certain flags/features.
You could even do something much simpler, like adding a comment to the related issues mentioning that you ran into these rough edges and that it made your life a little worse, or with a workaround that you found.
Alternatively, you can continue to write about how much free software sucks.

Cargo has never frustrated me like npm or pip has. Does Cargo ever get frustrating? Does anyone ever find themselves in dependency hell?
You try to use it as a part of multi-language project, with an external build tool to tie it all together, and you discover that --out-dir flag is still not stabilized over some future compatibility concerns.

Learning Rust by Building a CLI App
To create a new application we'll use cargo (a build tool and also a package manager for Rust. It is used for scaffolding new library/binary projects). So in your projects folder, you can run this command in your terminal:

Leaving Haskell Behind
> ...but at the end of the day Cargo is the reason that Rust is popular.
FWIW, maybe that's true for you, but there are numerous other advantages to the language for which many people choose to use Rust--some even "despite" Cargo: you see Google having had to put in way way WAY too much work to get Bazel working for Rust :/--that it honestly feels a bit like belittling an extremely important language to make this claim so flippantly.
> You can set a default build target for a Cargo project with two lines of configuration, no nightly features necessary...
This doesn't work as, as soon as you start setting target-specific options, it infects the host build, as they incorrectly modelled the problem as some kind of map from targets to flags. If you don't believe me, on your Linux computer, try cross-compile something complicated that will runs on a "least common denominator" Linux distribution, such as CentOS 7.
> Can you clarify what this is referring to?
Sure. I've Googled rust cargo target host bugs for you (which, FWIW, finds a number of bugs I've filed or have talked about, but it isn't as if I have a list anywhere). Note that one of these bugs is "closed", but I still provide them for context as a patch might have been merged but (as you'll find out if you read through all of these) it isn't stable.
https://github.com/rust-lang/cargo/issues/8147
https://github.com/rust-lang/cargo/issues/3349
https://github.com/rust-lang/cargo/pull/9322
https://github.com/rust-lang/cargo/issues/9453
https://github.com/rust-lang/cargo/pull/9753
The result of this work being left incomplete is that increasingly large numbers of "serious" projects--things I'd expect people in packaging land to have heard of, such as BuildRoot--are being forced to set the ridiculous environment variable __CARGO_TEST_CHANNEL_OVERRIDE_DO_NOT_USE_THIS="nightly" in order to get access to a flag that makes Cargo sort of work.
(And yet, I often see people surprised at how long it is taking for various of the more important clients to fully get into using Rust, as the safety issues are so severe from continuing to use C/C++: as you made the contention that you believe the reason why people use Rust is Cargo, I will say the opposite: the reason why we don't see more Rust is also Cargo.)

Rust vs. Go in 2023
What has worked for me so far:

(do the exercises!)
plus a little bit of:
https://doc.rust-lang.org/cargo/
and
https://doc.rust-lang.org/std/index.html
(There's no need to remember the last URL -- just google "rust xxx" and you will get the right page.)

lisp-koans - Common Lisp Koans is a language learning exercise in the same vein as the ruby koans, python koans and others. It is a port of the prior koans with some modifications to highlight lisp-specific features. Structured as ordered groups of broken unit tests, the project guides the learner progressively through many Common Lisp language features.
