FYI for @github users: You need to opt-out of this "#AI model training" setting before April. Though your public repos will be scraped anyway, you don't have to volunteer to be studied as a user. Not sure how this is opt-out with #GDPR, but it is. Settings > #Copilot > Features #privacy

The weekend theme is #AI + coding! A friend sent me this piece that mentions my comments on #freesoftware #opensource licensing and #genAI. LLMs have a place in our @ivycyber.com business but it's a very carefully controlled one, and not in the codebase. psafe.ly/TRySSC

🤔 I have yet to get it to trigger an actual browser crash without the "Guard rail stopped the party" mitigation stopping it. But like all #vibecode things, it's gonna be tough to diagnose ¯\_(ツ)_/¯ Without the CSP header controls (see the nginx example I put in the git repo) it might be dangerous.
