We’re seeing up to 14.5 million attempts per hour to exploit the #React2Shell vulnerability across @Cloudflare’s network. This is a very bad exploit. While our WAF is helping protect customers, it’s critical to update your React and Next.js instances as soon as possible.

Interesting: GitHub is removing all toasts from their UI due to usability and accessibility issues. I agree they tend to be overused, probably because they’re so easy to implement. There are often better patterns like inline confirmation/errors. https://t.co/cpZHzuDhEG

Dang, frontend’s public shaming the backend team at @perplexity_ai

I’m dying for the ability to rewind 15 seconds or capture a clip. Too many cursed moments to count and I can’t turn away or share them with others

OK so I’ve watched this for an hour since yesterday. It is unironically extraordinarily entertaining. The visual and audio horrors play out live (no repeats from what I can tell). Feels somewhere in between Adult Swim and sifting through YTP videos with a *very* high hit rate

How does Apple make these crazy video transitions as you scroll?

Let's recreate it with pure CSS with scroll-driven animations and view-timeline

That's right, no scroll event listeners!

Friendly reminder that I'm currently hiring @CloudflareDev. If you or anyone you know is in Austin (or willing to relocate!) and wanting to work with us, feel free to DM.

Chrome DevTools is, by far, my favorite mcp server.

By running these 2 commands in your terminal, you get to have Claude Code come into your browser with full power:

Launch a chrome browser:
> google-chrome --remote-debugging-port=9222 --user-data-dir="$HOME/.config/google-chrome"

Install the MCP that connect to the browser:
> claude mcp add chrome-devtools -- npx -y chrome-devtools-mcp@latest -u http://localhost:9222

Blessed by the Goodwill gods today. Rewatch TNG for the 3rd time or finally start DS9?

I've shared the full transcript of every agentic coding session from implementing the unobtrusive Ghostty updates and provided commentary alongside about my thinking and process. Total cost: $15.98 over 16 sessions. "Vibing a Non-Trivial Ghostty Feature" https://t.co/kRUSWyMSyW

Read Tufte. It'll change forever how you think about visualizing data (and more).
