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.

evm.storage now shows and tracks storage for unverified contracts, smlXL opensourcing bytecode storage layout analyzer
evm.storage recently can now show storage layouts and track storage of unverified Solidity contracts (it works for simple Vyper contracts, too, but is not optimized for Vyper atm). We also opensourced our storage layout analyzer, which makes it possible -- The tool symbolically executes a contract’s bytecode to infer its storage layout. At times, it produces layouts that are even more accurate than those generated by solc with source code!

How can I calculate the total gas used by calldata for a particular block?
evm.codes has a wonderful about the EVM section about how gas is calculated. The way calldata gas is calculated is quite simple:
-
Deploying a contract with raw opcodes?
very interesting question - I checked this using evm.codes and the answer is yes: one thing to note is that simply fallback still has to check for whether the sender has sent eth, but a payable fallback truly has no switch case before it.

Referring to the validator's staking address in Solidity?
https://evm.codes wonder which ones we'd be dealing with here and why it wouldnt work with fallback/recieve funcs
- Resources for Finding underlying OPCODE stack/register instructions?

Inline Assembly: Use the result of a function call as the argument to a second call?
the ADD opcode is not concatenation, it is arithmetic addition. According to evm.codes, the fourth argument to delegatecall is the bytesize to copy from the memory (size of the calldata) - so adding the msg.sig (as a number) to the size of the calldata doesn't make sense
