I came across this interesting product for structural/geotechnical monitoring of cracks in 3 dimensions. Most crack monitors are designed for monitoring in 2 dimensions, this one can measure movement out of the plane of monitoring. I like that the markings are laser-etched so the simple device should last for a long time. Price is $40/each from Quality Plus Engineering, LLC.

ASCE: Cease and Desist over Video Spoof
The American Society of Civil Engineers ASCE sent a cease and desist letter to the owner of the Levees.Org website notifying them to remove a video spoof of its post-Katrina levee inspection. Of course, through the wonders of the internet, Levees.org removed it from YouTube, but someone else posted it again. And because of all the fuss, it’s more popular than it would have been otherwise with over 16,000 views at the time of this post. Click through to watch it.
