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.

Nvidia releases open-source GPU kernel-modules
The carl firmware at https://github.com/chunkeey/carl9170fw should put that argument to rest. That is Wifi firmware source code for the Wifi I currently use.
Easily changed likely means there's a physical knob somewhere that you could accidentially poke as a layperson.
Not that you get a three year CS education, figure out how your distribution packages dependencies, install the correct embedded toolchain (good luck), find out exactly which chip is in your device, fetch the proper firmware source code in the right version, build the thing, figure out how to flash the result onto the chip / read the Linux kernel sources to figure out the filename inside /lib/firmware. That's not easy.
Even if this entire process was packaged (it is--see <https://packages.debian.org/sid/firmware-linux-free>), it probably still doesn't count (or at least shouldn't count) as "easily" changed.

There are some cards with open source firmware, you might be able to modify it to do something like that.

Framework: Open Sourcing Our Firmware
I've extracted the Chromium-EC encryption functions, they are convenient for signing / verifying firmware on other platforms. Chromium-ec is nice for example code like this:

On the other hand, if you are looking for some generic embedded system code all in C, here is our library:
https://github.com/nklabs/libnklabs
I think it's most unique feature is the embedded schema-based database- so you can save things like calibration and configuration information in local flash memory. Recently I've been adding device drivers for all common devices I can find on break-out boards for the Arduino and Raspberry-PI communities.
What are some alternatives?
