OMG, don't try to build Open vSwitch from source if you can avoid it, if you are on Ubuntu just follow these steps to apt-get it, and then it builds the database and runs itself.
The problem is that most normal people just want to run ovs in a VM with mininet, but I wanted to run it on a real bare-metal server with actual traffic.

Kinect-based 3D scanning software
I am looking for some alternatives to 123D Catch. Here is one, KScan3D, which says "With KScan3D software and Kinect or Xtion sensors, you can scan real objects and export 3D models in minutes."
Other options include Skanect, and Reconstruct Me.
Apparently Skanect has a Mac OS X version, and can work with Structure Scanner (attached to your iOS device and streams to your OS X computer), or Asus Xtion & Primesense Carmine and Kinect for Xbox (but not Kinect for Windows). Details on use with OS X are here.

Dorkbot SoCal's overlord emeritus has moved to Vancouver, but will return to us through the power of videoconferencing to narrate his travelogue of the Chinese maker/hacker culture including the 2014 Shenzhen Maker Faire, Seeed Studio, theChaihuo Hackerspace in Shenzhen, as well as the Xin Che Jian Hackerspace in Shanghai.
Garnet is now the Canada Research Chair in Design and Media Arts at Emily Carr University of Art + Design in Vancouver Canada, and previously was previously Artist in Residence and Research Scientist in Informatics at UC Irvine. And he has built robots controlled by cockroaches :)

Thomas will talk about how you can use 3D capture software such as 123D Catch to make your own digital holograms with Zebra Imaging.
Safecast bGeigie build event in Santa Monica
bGeigie Workshop Santa Monica, CA November 1-2, 2014.
Build a GPS-enabled, data-logging, hand-held radiation detector, learn about citizen radiation monitoring, and connect with a growing network of people motivated to measure radiation in their environment and share their data with others.
Safecast, the Natural Resources Defense Council (NRDC) and IMI International Medcom, Inc. will host a bGeigie workshop at NRDC's offices in Santa Monica, CA on Saturday, November 1 and Sunday, November 2, 2014. During the first day of the workshop, participants will solder and assemble Safecast's Good Design-winning bGeigie, learn how to use their detectors, and hear from individuals and groups involved in citizen radiation monitoring. During the second day of the workshop, trips will be arranged for participants to log radiation measurements in the field, and practice uploading and mapping their data.
Read blogs from Safecast co-founder Sean Bonner, IMI International Medcom’s CEO Dan Sythe and NRDC health physicist Bemnet Alemayehu about the bGeigie workshop we held in Washington, DC this past spring. For more information or to register for the event, please contact NRDC’s Matthew McKinzie atmmckinzie@nrdc.org. The bGeigie kits for this event (cost $450) can be ordered in advance from IMI International Medcom. Please let us know if you or your organization would like to inquire about support to participate, as we want to grow this community.

Making a Full Color White Light Hologram
Using 123D Catch iPhone app, I captured a model of my wife Carla, and then took that an made an 8x10" full-color white light hologram from Zebra Imaging:
My thoughts: 123D Catch is pretty easy to use to capture a 3D mesh. Making the hologram from the mesh on 123Dapp.com was pretty easy as well - they interface well with Zebra Imaging. I probably should have fixed up the mesh a bit in Blender or MeshLab, but I had to use a coupon before it expired. The hologram has a kind of "grid" to it, but you don't tend to notice it very much. The hologram is not very efficient, you need to illuminate it with a very bight light to see anything. I ended up purchasing an Ikea Jansjo Desk Work Led Lamp Light, which does a good job of illuminating the hologram because it is a point source, single white LED. Pretty awesome!
Here is what the mesh looked like in MeshLab after I captured it:

Crashspace's Sparkles in 3D
I did a quick 3D model of Crashspace's "Sparkles" the pony soldering iron using the iPhone 123D Catch app, here are the results in MeshLab:
Needs some work in Blender. You can see that I put Sparkles on top of a drill press to capture the model.
