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.

Retro personal computer ads from the 1980s
I think the novel and interesting tech is still happening, its just that without the colorful ads for it on TV, and without the software being packaged up and sold with pretty box art that you can physically hold, it doesn't feel as much like a capital-E Experience. It's probably the Internet's fault that we don't do things like that anymore, but the upside is that we now have access to so many ideas and applications from all over, even ones that aren't commercially viable.
Some that look exciting to me are: an AI that lets you animate still photos realistically [1], a simple website that guides you to discover new parks, eateries, and other places near you [2], an AI that colorizes old black-and-white photos/video [3], a Street View style map of the game world from "The Legend of Zelda: Breath of the Wild", with some 1st person 360 degree photos [4], and a tiny game engine that lets you distribute your whole game physically via printed QR codes [5].
If marketing and graphic design people ever felt like getting together to do some 'side projects', I vote that they should make print ads for apps/websites that they like :)

Storing Games In A QR Code
Another "game in a barcode (or three)" project: https://github.com/kesiev/rewtro

QR codes are technically a type of optical storage media... putting them in the same category as CDs and DVDs.
Here's something you might find interesting - an 8 bit virtual console which uses QR codes to store video games. I came across it a few weeks ago and think it's pretty neat.

Is there a pointer equivalent of declaring an array?
In addition to what other posters suggested, it could be a good idea to try assembly languages as a way to manually work with locations in memory. Something like Octo could be fun if you want to try memory manipulation without worrying about real-world complexities like syscalls and memory alignment. If you want something extra challenging, you could always try x86 / amd64 assembly. Some C compilers even support inline assembly if you want to mix C and assembly.

How do I make a "game" for Chip8?
Yes, Octo is the most used tool to create CHIP-8 programs today. John has a little introduction text for writing in its dialect here: https://github.com/JohnEarnest/Octo/blob/gh-pages/docs/BeginnersGuide.md

Feedback on my very own C++ CHIP8 Interpreter/Emulator
I also want to thank you all for all the advice you gave to me and others about CHIP8. It was very helpful to read some posts here ! I also used John Earnest's OCTO a lot for debugging.

Is chip 8 emulator flicker normal?
The octo FAQ touches on this "pre-xoring" technique, and theres a worked example of doing this data preparation in macros. I've also written varioustools that can handle the xoring for you.

Executable PNGs
In my own system, Octo[0], I encode programs and their metadata in a similar steganographic fashion in GIF files. As others have noted here, both GIF and PNG offer extension mechanisms and ways to embed "comments", but popular image-sharing sites universally re-encode images and discard this data. The advantage of GIF over PNG (for my purposes) is that I store an arbitrary payload in a fixed-looking image by creating additional frames of animation.
In the past, I've also used a different technique- if you simply concatenate a PNG onto a JAR (which is really just a ZIP archive) you end up with a file that acts like a PNG unless you change the extension to JAR, in which case it acts like a Java executable. This works because the PNG header is at the beginning of the file, while the ZIP header is at the end. Nowadays, though, desktop Java is pretty much dead, so it's a less exciting party trick.
