For years we have been using several layers of Java, Java Native Interface, and native driver code to support common access to sensors from multiple Probeware interfaces from different vendors. We’ve been calling these layers the org-concord-sensor framework. Our Java/OTrunk framework which has supported many kinds of interactive educational activities uses the org-concord-sensor framework to […]

A new Web site permits you to hurtle asteroids and comets into the Earth to see what havoc you can create. The cool thing is that it uses an impact calculator created in 2002 for use by NASA and the Department of Homeland Security. Check it out at Impact: Earth and get ready for your […]
Every great story deserves an equally great ending. In that vein, I was thrilled to read that Mikal Hart’s wedding present to his college friend has finally been opened. The story lasted a year, and involved the first instance I have encountered of reverse geocaching. Put simply, Mikal turned the notion of geocaching — in […]
I love this. Nigel Leck, a software programmer, got bored with constantly responding to climate change skeptics on Twitter. So he built a chat agent to do it for him.
