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.

How do you find underlying addresses or balance/transactions from a Bitcoin xpub, zpub, or ypub address?
pip3 install git+https://github.com/mcdallas/cryptotools.git@master#egg=cryptotools

A from-scratch tour of Bitcoin in Python
I’ve made something similar in order to learn how everything works and made it into a python library. Everything is in pure python with no dependencies, only std lib. I’ve implemented all the crypto stuff, address generation including HD, transaction serialization and even the bitcoin script. https://github.com/mcdallas/cryptotools

- If I sign multiple messages with the same nonce, my private key can be extracted?

Tell HN: It looks like all Bitcoin hardware wallets can phone home
> Show me an actually malicious hardware wallet that becaves as you've described, and you'll have made your point.
I'm not the OP and although I agree with you, you may be interested in the corollary for a "stronger" attack than OP defined:
https://bitcointalk.org/index.php?topic=581411.0 and https://github.com/tintinweb/ecdsa-private-key-recovery
Constructing such an airgapped hardware wallet is as trivial as a raspberry pi running a patched bitcoin client. In my opinion the more realistic construction than a that of "Reflections in Trusting Trust".
What are some alternatives?
python-ecdsa - pure-python ECDSA signature/verification and ECDH key agreement
bitcoin-recover-privkey - Proof of concept of bitcoin private key recovery using weak ECDSA signatures
RsaCtfTool - RSA attack tool (mainly for ctf) - retrieve private key from weak public key and/or uncipher data
bitcoin_recover - An open source Bitcoin wallet password and seed recovery tool designed for the case where you already know most of your password/seed, but need assistance in trying different possible combinations

blocktracker - A tool to go up the transaction tree of an address on the Blockchain.
hd-wallet-addrs - A command-line tool that performs Bitcoin wallet address discovery.
walletlib - Unified interface to work with cryptocurrency wallet.dat, .wallet, .key files. Can automatically attempt to figure out what type of coin a .dat wallet contains via its prefix.
