Every spring, thousands of fish swim through the Oudegracht in Utrecht, looking for a place to lay their eggs. But the Weerdsluis is often closed. The Fish Doorbell helps. When you spot a fish on the livestream, press the doorbell. The lock keeper will check to see if the lock can be opened.

Another reminder that a 13-year study found that protected bike-lanes led to a drastic decline in fatalities for all road users. ALL ROAD USERS. And painted bike-lanes? No safety improvement at all. For sharrows, it’s actually safer to NOT have them. Via

The AI industry wants us to believe AI superintelligence is the real threat from generative AI. But that narrative was crafted to distract from the many ways genAI is being used to tear our societies apart, as we saw this week when a deepfake video rocked the Irish election. It must be reined in.
