These are a few things I found interesting on April 22nd:

• Google Transit – plan trips using public transportation & Google maps
• What is Mind Mapping? (and How to Get Started Immediately) – I used mind maps to take class notes from 9th grade to about 11th grade. I took a lot of shit for it, too, from teachers and classmates alike
• 511.org – Bicycling – Bay Area Bicycle Maps – more bike maps, for SF Bay Area residents
• Bike Trails, Paths & Routes From Over 40 Countries at Bikely.com – Find a route, look at it onscreen, or download a .gpx file to your handlebar-mounted GPS unit
• Want to Remember Everything You’ll Ever Learn? Surrender to This Algorithm – Profile of Piotr Wozniak, creator of the “SuperMemo” software for enhancing memory. Echoes techniques developed by my wife’s grandfather for his Ed.D. in probably the 1940s or 1950s — though he used index cards
• What is the Learning Curve? – Brilliant, funny explanation for those who dimly sling around the term “learning curve” without thinking about it
