We're happy to announce [un]prompted is back, October 27th to 29th, in San Francisco. Registration and CFP are now open. Waiting a whole year just made no sense to us considering the rate of change, and the community forming around the event. unpromptedcon.org/ A thread

The person who built Claude Code just showed exactly how to use it. 30 minutes. Free. Straight from Boris Cherny himself. Bookmark this before you forget. Most people using Claude daily are missing 40+ features hiding in plain sight. This single session is worth more than any $1000 course.

We just added a new mapping to iotsecuritymapping.com/ - the CSA @cloudsa IoT security controls matrix. This should be useful for companies and governments looking to see how the controls map to @ETSI_STANDARDS EN 303 645. #iot #security #standards #defragmentation @scriptingxss
