The All-Knowing Senior Dev and the Junior's PR
Description
This meme uses the 'Gru's Plan' meme format. The first panel shows Gru pointing to a board that says 'Junior dev opens a pull request.' The second panel shows a close-up of the board, which now says 'It has 1,200 lines of code changes.' The third panel shows Gru looking back at the board, confused, as it now reads 'Senior dev comments: 'lgtm'.' This meme humorously depicts the sometimes-unpredictable nature of code reviews, where a senior developer, either out of trust, lack of time, or sheer apathy, approves a massive pull request with a simple 'looks good to me.' For senior engineers, it’s a funny take on the pressures of code review and the occasional need to trust your team's judgment, even when you don't have time for a deep dive

There are two types of senior dev code reviews: a 200-comment Socratic dialogue on a two-line change, and 'lgtm' on a PR that refactors the entire authentication service. There is no in-between
The cheapest encryption algorithm is six months of code rot - future-you can’t decrypt a thing
After 20 years, I've learned that git blame is less about finding who wrote the code and more about discovering it was you, six months ago, with a commit message that just says 'fixes'
The real senior move is writing code so clever that even you need a debugger and three cups of coffee to understand it six months later. Documentation? That's what `git blame` and archaeological excavation skills are for - because nothing says 'job security' quite like being the only person who can decipher your own cryptic variable names from 2019
At senior level, memory is a distributed system - grep, git blame, and that stale README you forgot to update after the last hotfix
Senior pro move: Treat juniors as living Javadoc - queryable, updatable, and always on call
Human memory has a TTL shorter than a sprint; serialize intent into tests, names, and ADRs before rebase --squash turns it into archaeology
