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.

All About EVM Instructions And Opcodes:
It is very important for the smart contract developers and auditors to undertand that how solidity based smart contracts/EVM executes its fundamental tasks behind the scenes to get deep foundation of EVM. To know more about the other EVM opcodes, please visit Here and if you want to play with these opcodes in the real time playground, please visit EVM codes playground website .

Ethernaut: 13. Gatekeeper One
Debug the transaction in Remix to get to the GAS opcode, which is what gasleft() is doing in the background. There, we will look at the remaining gas field in "Step Details". You can easily get there in several ways:
-
What is Gas on Ethereum (and other blockchains)? Deep dive
Each OPCODE has a fixed gas cost. The gas cost of a specific function within the smart contract is the sum of the gas costs of all it's OPCODES. You can find a list of all OPCODES and their associated gas costs here if interested.

-
Gas fees should be zero if a transaction didn't go through
And so, each instruction is given a metric that represents how intensive it is to execute, which is that instruction's gas cost, and users have to pay a fee based on how much gas in total a transaction consumes, which is the solution that the Ethereum devs (and the devs of other smart contract chains) have landed on, to address the above issue.

Might be a dumb question: Are there any ETH L2s that have a java virtual machine for transactions?
The EVM has a smaller instruction set of opcodes that are very tailored to Smart Contract development compared to what the JVM offers which is a wider set required for programming almost anything.

Precompiled Contracts in Neon: A Case Study of ERC-20 Wrapper
The Neon EVM core program is based on the Sputnik VM, an implementation of the Ethereum Virtual Machine written in Rust. Sputnik VM includes a feature to embed third-party Rust code that can be invoked from Ethereum contracts. This embedded code is known as a “precompiled contract”.
