Google Built a Free Design Tool That Generates Production Code From a Sentence — Then Added Multiplayer

Google Stitch does it free. A year later, Google added real-time multiplayer, a streaming design agent, and voice input. The design industry noticed.

Google's Gemini Omni Is the First AI That Creates From Anything — Here Is What That Actually Means

Google's Own Cleanup Job Crashed Cloud Services Across 4 Continents — and Then Made Recovery Worse

On May 29, 2025, a Google engineer deployed new quota-checking code to Service Control — the system that authorizes every single API request across Google Cloud. The code had a bug: it couldn't handle a null value. But the bug was invisible during deployment because it could only be triggered by a specific type of policy data that hadn't appeared yet. Two weeks later, on June 12, an automated system pushed a routine policy update containing blank fields. The policy data replicated globally within seconds. Every Service Control binary in every region hit the null pointer, crashed, and refused to restart without eating itself. Spotify went down. Discord went down. Snapchat went down. Google's own status page went down. And when engineers deployed the fix, the restart surge overwhelmed the infrastructure — making the recovery worse than the crash.
