• Got some more feedback on my PR, implemented it, marked it ready for review.

• Learned git show and git diff. Difference between them, show is for single commits, diff is more generic and can do branches or any two commits. git show shows change for latest commit. git diff <target-branch>..<working-branch> is nice to see what your pull request is looking like.

• Learned how to revert a merge.

• Learned to rebase instead of merging main branch into working branch. In all honesty I can’t believe I didn’t know this before lol. Also realizing how nice rebasing is to just organize your different commits in your branch—will be doing this by default now.

• What is a phantom payment? I see this all around the repository but I don’t actually know what it is.

• Was reading some documentation about failure codes (PERM|15) where it talked about the fact that they returned differentiating errors in certain cases, it allowed for a forwarding node to be able to probe nodes with HTLCs of different amounts or cltv_expiry’s in order to find out the final destination. Pretty neat.

• Started on cryptopals. Did the first 4 challenges of set 1. So far they were pretty simple, but I sometimes would get caught up overengineering or thinking it was harder than it was. Lacking GitHub Copilot here has been very annoying, and my Helix autocomplete always has somewhat of a delay. Will need to look into that…

• Got a bunch of PRs to review after asking in the discord. Exciting!
