I found a new use for #ClaudeCode. I fall down rabbit-holes on code exploration; changing 100s of files w/o worktrees. This time I built a new UI component library & swapped out 20 years worth at once. Claude rewrote the #phpStorm workspace.xml file & staged 80 commit changesets w/ hunks for review

Python's namedtuples apparently have major overhead. I replaced my BFS queue state for Day 10 Part 1 with tuples and the runtime dropped from 45s to 14s. I'm sure I can optimize it further with just math, but the solution is only ~7 lines of code. #AdventOfCode #Python #Programming

Handy tip for Safari screencasts: Preferences -> Websites -> Page Zoom -> (host). When I started screen recording web apps I always used to Cmd-Plus or CSS override "zoom". A much better approach is to override the page zoom by host in Safari's preferences. #safari #screencast #video #tips

It should be noted that markets have underreacted to the tariffs. A 30–50% sales tax (aka tariffs), will wipe out entire industries. The -7% drop this week doesn’t reflect the full damage. It’s an optimistic move assuming the tariffs won’t stick. The impact, if enforced, would be far more severe.

you don’t necessarily want the system creators to actually write the docs. but if the docs are written by people with no connection to the system that who are guided solely by user feedback, you’ve also failed. docs should be written by people hopelessly torn between the two perspectives

It was really valuable for me to stay at a single company long enough to live with the consequences of my own engineering decisions. To come face-to-face with my own technical debt. It takes a few years for this to play out but IMO it's an important part of engineering growth.
