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.

Ask HN: What Are You Working On?
What the hell, here are a bunch of half-baked ideas that I haven't made time for because I'm lazy and stressed out and exhausted:
1. Designing a protocol and air interface for an amateur radio cellular network. This started out with some spread spectrum experiments and an interest in low-probability-of-intercept (below the noise floor) communication. The idea I have now is sort of a cross between APRS and DMR using modern modulation techniques. The network would consist of amateur rooftop "cells" with internet connections, and mobile transponders that communicate with those cells. There'd be some sort of callsign or key based addressing scheme and IP-like network topology discovery. Everything will be authenticated. I'd love to have an encrypted mode, but unless the laws change, it probably isn't going to happen.
2. Open-source firmware or gateware implementation of a USB PD controller that supports entering/exiting alternate modes properly. Inspired by Kate Temkin's Luna project [1]. I got the impression that PD was out of scope for LUNA, at least for the time being, but it would be really nice to have both a USB and PD stack that could be integrated onto a small, inexpensive chip without the proprietary mess.

A header-only C implementation of C++ <algorithm>
Well, I do like mine better, which is closer to the STL, and for all containers. https://github.com/rurban/ctl/

A simple hash table in C
search for htable or hashtable in thousands of open source projects. only a minority has worse hashtables than this one (clisp, perl5 e.g.).
For better ones I would point to my linked list implementation: https://github.com/rurban/ctl/blob/master/ctl/unordered_set.... (because it has various security policies, nobody else has)

Popular Data Structure Libraries in C ?
C Container Template Library, Rurban Variant (CTL) - The page for unordered_map reads "Implementation in work still".

C Template Library
There is also the rurban variant variant of CTL which is more complete.

Better C Generics: The Extendible _Generic
The prototype of CC used this mechanism to provide a generic API for types instantiated via templates (so basically like other container libraries, but with an extendible-_Generic-based API laid over the top of the generated types). This approach has some significant advantages over the approach CC now uses, but I got a bit obsessed with eliminating the need to manually instantiate templates.

How different is C++ from C? Contrasting simple Unix SORT programs
But the most common that I know of is this one: https://github.com/tylov/STC. There's also this one mentioned above https://rurban.github.io/ctl/
- C++ containers but in C
- STL in C

On HASH-TABLEs performance
I'm also working on a proper one, but got sidetracked. https://github.com/rurban/ctl/blob/hmap/ctl/swisstable.h
