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.

The Rise of Fully Homomorphic Encryption
For clarity, let's assume the hospital stores its records in plaintext. For the pharma company, the hospital encrypts the patient records with a secret key. Now they let the pharma company run their homomorphic algorithm and send the values back. Only problem is the pharma company can not read those results without having access to the key. FHE is completely redundant in this use case - the hospital could have simply run the pharma company's SQL and audited the code and outputs.
What is FHE actually good for then? Let's imagine you are a top secret agent and you get instructions to fly to Bulgaria as a part of your mission. You have other hostile agents constantly monitoring you, trying to understand your next move. But there's a problem - to buy a plane ticket to Bulgaria you need to know the name of it's capital city. You can't just type it to Google, because these other agents have infiltrated the Google servers and see what you search (assume once you actually know the name of the capital, you somehow buy the actual ticket without "them" knowing..)
Lukcily though, CloudCorp offers a public homomorphic query service for all world capitals. This service allows you to send a query for the capital of any country over an intercepted connection, and get back the result. Even if the hostile agents had infiltrated CloudCorp and were monitoring all your comms, they would not be able know which country's capital you just queried.
How such service would be implemented is explained in good detail in this tutorial: https://github.com/homenc/HElib/tree/master/examples/BGV_cou...
P.S. The capital of Bulgaria is Sofia.

C++ members chaining
While I was searching for homomorphic encryption tools/libs, I stumbled upon this.

Fully Homomorphic Encryption by Google
FHE has been around for a while now, IBM: https://github.com/homenc/HElib and Microsoft: https://www.microsoft.com/en-us/research/project/microsoft-seal/ both have their own (much more mature) FHE implementations.

AD&D 1e Level by Class and Experience Points
Shameless plug ahead (I wrote the thing, but it's free and open source, so not making anything out of it):
-
Moebius Toolkit 0.2 released: a Windows/macOS/Linux app for making some charts about the game (and some extras). Now with a forum on Gibberlings3.net
The app is totally stable (to the best of my knowledge), so don't fear by the 0.2 version number. The main reason is that I plan to add some features so eventually it can be an up to date and maintained replacement for EEKeeper, and by then it will probably be 1.0. The project is open source and cross platform (Windows, macOS and Linux versions available). And there is a version which just works (in a limited fashion, and very ugly) on the browser.

C++ members chaining
You can look at the full implementation of it if it helps, but it's fairly trivial to do members like this. They just return a reference to the class like this:

And the code is and will always be online with a free/open source license.

Baldurs Gate 1/2 Experience-gain Adjustment Tool
I also have a project that parses the game files, but I've made a very slow progress into just supporting reading all of the fields of some of the files (not yet CRE and DLG), and little else. It's done in C++ as well. Feel free to check it out if you want.
