While I'm personally enjoying having a less emoji-centric career now, it's very cool and gratifying to see Emojitracker take on a new life and data source. Hat tip to the team!

My favorite part about Jujutsu (jj) using `k-z` "reverse hex" characters for change IDs (versus git using hex `0-9a-f`) is that for 8 character abbreviated IDs, the only valid English words that could appear are "postpunk" and "stopwork".

Upon request, made a quick CLI wrapper around my method to run #golang fuzz tests in the background on Apple Silicon efficiency cores only, so now you can `go install` it instead of making a shell alias: github.com/mroth/go-bgt...

I’ve long relied on CDC wastewater data to gauge COVID community spread and make informed decisions about what precautions to take. For the past year, I’ve used a custom iOS/macOS widget I wrote to help me keep tabs. If you would find it useful, I finally shared it on the App Store: apple.co/4glESi8

Favorite shell alias for #golang dev on Apple Silicon chips:

alias bgtest='GOMAXPROCS=`sysctl -n hw.perflevel1.logicalcpu` taskpolicy -b go test'

Runs tests on efficiency cores only, perfect for fuzz testing (`bgtest -fuzz FuzzFoo`) in background without affecting normal work.

Intriguing to see bsky starting to potentially gain mass adoption. Been enjoying my little corner of the fediverse the past few years since Twitter imploded, but it's a bit insular.
