Nothing to say; just enjoy some great engineering and computer science links!
- Let’s start out with a video of a robot which juggles 5 balls almost flawlessly. Turn the volume down because it’s noisy.
- Some local news: someone sued Portland Public Schools to remove Wi-Fi on the basis that it exposes kids to radiation.
