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.

Re-use of an address.
Here is an example script you can use to mix randomness from multiple sources - dices, the microphone, haveged.
- I made an Electrum seed with a cat and it works!

frozenkrill: a minimalist Bitcoin wallet focused on cold storage
In my script DoubleSlow Keystretcher I am handling the key stretching differently, I am using not only Argon2, but also Scrypt.

How to use Electrum on an air-gapped computer by transferring transaction data into the air-gapped computer by hand (with the keyboard or mouse only)
More time it takes to derive the seed (with doubleslow). It can be configured to run for hours.

Lastpass Security Incident Update: "The threat actor was also able to copy a backup of customer vault data"
This is why I wrote doubleslow.

I made an Electrum seed with a cat and it works!
The key stretching with the "seed extension" (also known as "extension word" and "passphrase") in the BIP39 specification is very weak (PBKDF2 using 2048 iterations of HMAC-SHA512), this is why I wrote Doubleslow Keystretcher.
