Neues von #Sarkozy:
Über die 20 Tage in Haft veröffentlicht er das “Tagebuch eines Häftlings”.
Dazu G. Faure in @lemonde.fr
“20 Tage im Gefängnis und Sarkozy macht daraus ein Buch. Das ist so, als würde ich ein feministisches Essai veröffentlichen, weil ich die Spülmaschine ausgeräumt habe.“

What's hilarious is that competent programmers, as well as people studying programming for the very first time, know that all code you write after about 4 hours is garbage. Totally useless, none of it worth salvaging.
Actual programmers hear "I coded for 36 hours" and hear "I gooned for 36 hours"

This is fantastic and @zacsweers.dev deserves all the praise but it also is gonna give you a false idea of what Z is like as a maintainer and author, what the project is like, and how you might achieve something like this yourself
Hot take: Dependency Injection on Android just got a huge upgrade!!
Square just moved Anvil to maintenance mode to adopt Metro - a DI framework built by ONE PERSON that's 47-56% faster than Dagger+Anvil.
This is what "individual developers changing ecosystems" looks like 🧵

If you happen to be in Amsterdam at the end of November, come say "hi" at the Kotlin Dev Day, where Duncan McGregor and I will be doing 47 refactorings in 45 minutes (see kotlindevday.com/program). I will also be just hanging out with Kodee on the 28th, so happy to chat or do a code kata 🧐
