Sometimes complaining to GitHub works! Org owners can now prevent even users with their own Copilot license from summoning it in your repos. Thanks @cassidoo.co for putting me in touch with someone! github.blog/changelog/20...

I can't get over how happy this photo makes me! Ten (from Singapore) and David (from Ireland) have been responding to my newsletter coding questions for YEARS and realized they were both in Japan while answering this past week, and met up! I *love* seeing these kinds of connections happen!

My fave internet trend is students asking teachers to sign an old picture of them that they found on Facebook or something, ugh, it's beautiful to see their panicked cringe

"To take a fine idea and make something great of it... that is what real art is!" - Antonín Dvořák Thought this would be a good kickoff quote to this week's newsletter issue! Come read something, learn something, and practice some coding while you're at it: cassidoo.co/newsletter/

the hard parts of building a business are - solving a real problem for real people - ignoring shiny ideas that are fun but distracting - prioritizing boring stuff that moves the needle - connecting with customers if anything, AI makes it *harder* to build a successful business
