Was working a #leetcode problem with a friend and was surprised that `string.count()` had better performance than looking up counts in a precomputed dict.

#python can literally iterate through an entire list faster than it can lookup from a dict...

Post ideas:
1. What to do when ArgoCD gets your diff wrong.
2. How does chromium check if you have visited a URL or not. Also, who came up with this?

Interesting to see how a new JS engine compares to V8. Is it as optimized?

Found a nice #leetcode problem in chromium: issues.chromium.org/issues/45590...

Issue to use linear search for small N arrays. This avoids the O(logN) cost to sort that Binary Search requires. Is 32 elements too small for N though?

Going through #leetcode and the biggest insight I need to gain is what are the traits of a problem that identify which pattern to apply.

#claude is extremely helpful to review _why_ we should choose a particular solution. Many of the discussion posts miss this.

Been exploring #argocd source code today with #claude. One of the most trying problems #argocd users face is when the diff isn't clean but should be.

Check out github.com/argoproj/arg... for many testing examples. The tests compare a config to an expected live config.

I’m doing leetcode after not doing it for a while and I am astonished at how tedious sliding window implementations are.
