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.

Tools a Data Scientist should know:
If you're an R user, stringr + its cheatsheet gets you very close to remembering what to do without needing to look further!
-
JSON to PDF Magic: Harnessing LaTeX and JSON for Effortless Customization and Dynamic PDF Generation
For more information on how to use ggplot2 and create charts consult the ggplot2 official page or the ggplot2 cheat graphic.

Best packages to learn?
I'd suggest you have a look at cheatsheets (or download them from GitHub) if you want to get to know your way around a package or set if functions, it saves you a lot of time.
-
How do I make these shapes (pictured below) in ggplot?
You could use geom_hline and geom_vline, geom_abline, or geom_segment for this. (The ggplot cheat sheet is very useful for answering these kinds of questions, BTW.)
-
Why does my scatter plot look like this?
I can't say for sure because I don't know what your ultimate aim is for your visualization. Check out the cheat sheet for ggplot2 here.
-
Import from Excel
Finally just do your analysis. You should also should give a try and see the cheat sheet for data importing on the tidyverse package.
-
[Request] How to best visualize percentages with R?
That said, when I’m trying to come up with an interesting way to visualize data, I find the ggplot cheat sheet very helpful: https://github.com/rstudio/cheatsheets/raw/main/data-visualization-2.1.pdf
-
Need help with variables
Here's a cheat sheet: https://github.com/rstudio/cheatsheets/blob/main/strings.pdf
-
Data manipulation in R
The cheat sheet of the stringr package should give you good overview of string manipulation/ regex in R.
-
I'm trying to recreate this plot but I keep failing
I would very highly recommend that rather than trying to get started by translating an existing graph, you check out some documentation about ggplot first. If nothing else, the ggplot cheat sheet from RStudio should help explain what the component parts of the code are, and that might help you figure out what you actually want to do.

Ask HN: Does anyone Lisp without Emacs?
Racket (https://racket-lang.org) has an IDE (DrRacket) which isn't EMACS. ARC (which powers hacker news) is (was?) written in Racket.

Douglas Crockford, author of ‘Javascript: the good parts’ and ‘How Javascript works’ will be giving the keynote presentation From Here To Lambda And Back Again at the thirteenth RacketCon.
Nice! Repeating a comment I just made on HN: I signed up for RacketCon, will be joining remotely. I am looking forward to it a lot. Usually I use the Racket language perhaps for 10% of my personal projects, but I am currently writing a Racket AI book, so all things Racket are of current interest. Past RacketCons have been a lot of fun. I usually use Common Lisp, but Racket is batteries included Scheme, and more, and is a very pleasant language and ecosystem. Just in case you don’t have Racket installed: https://racket-lang.org/

Ask HN: What is the most suitable Scheme implementation to learn today?
I'd suggest Racket (https://racket-lang.org) which is a batteries-included language environment that includes scheme and has a lot of high-quality documentation.
Guile (https://www.gnu.org/software/guile/) isn't quite as learner-focused but is another great choice.

What Programming Languages are Best for Kids?
How did I get to the bottom of the page and not ONE person has recommended racket?

Setting up a Scheme coding environment in VS code?
The Racket fork of CS supports Apple Silicon natively, and can be installed independently: https://github.com/racket/racket/blob/master/racket/src/ChezScheme/BUILDING Chez adds a few features (threads, ffi, ...) to R6RS; there is a useful combined index to TSPL4 and the CS User Guide at http://cisco.github.io/ChezScheme/csug9.5/csug_1.html

Is SICP an overkill for a 14 year old?
If you're using SICP in Scheme (or are you doing the JS version?) then you may want to look at How to Design Programs. It uses Racket which is a Scheme descendent so much of the language you've learned in SICP will work in it without issue. It also has a pretty good set of GUI and drawing capabilities you can find through the Racket docs page and will use some of with HTDP.
