Cloudflare open sourced an OAuth library that was almost entirely vibe coded using Claude. They also shared the prompts that led to completed library which is an interesting study.

Tried to reserve 4 seats next to each other for a movie where there were a total of 5 seats remaining free in the row

The web app did not allow booking seats to have an empty seat left so was impossible

But check was on client-side: so I overrode it

Love being a dev sometimes

Lovely comment on my piece about hand-drawn illustrations: “Keep to a low tech approach to maintain a low barrier to idea flow and capture. Efforts to polish the presentation are better used to polish the idea.”

Others have noted it but I will too: The big reason Bluesky is so hot right now is that the people who add value to social media - the frequent posters in specific fields - are here now, talking to each other and creating the "spectator value" that draws users and attention.
