Completed the 3D print of the PiVE. It’s a four cell build designed to hold a Pi3 in each cell and provide adequate cooling in support of distributed computing.

Pi2–Tank/Crawler build
Received my tank/crawler chassis from China yesterday. Err, sort of: 
No instructions but should be straight forward. The is no lynch-pin in either track so the track must be mounted before the last wheel is installed. Hmm, but which wheel? The motors are heavy, 12 volt DC with transmission attached. Should be a high torque/low speed crawler.
How to build a Pi2
Just received a Pi2 and am in the process of building it. You can see how to do it HERE
Server upgrade
Upgraded the FC 17 server to Ubuntu. FC 17 was “way out” of current Fedora release and Fedora changes too often. Ubuntu is a more stable “release” platform and should continue on until 2017 with ongoing support.
Ubuntu’s implementation of some servers is quite a bit different from a configuration perspective when compared to Fedora. This required some additional re-training during installation of these servers. Two days after the bulk of the effort was complete I noted that I had loaded the “wrong” database for the website forcing me to locate and reload the latest one (this one).
You really “forget” how much is involved in moving servers. You make every effort to save all configuration files but there are always “some” that fall through. Also servers are implemented differently across some distributions. Apache is one example in moving from Fedora to Ubuntu.
Baking a Raspberry Pi
All parts are here. I think I will start baking the Pi. See RASPI-baking the pie in the sidebar for ingredients and “baking” instructions.
GPU (NVIDIA) installation on Fedora 17
This took a while. There were so many online guides and each had different results, not all positive. I tried Fedora 17, Centos 6, and Ubuntu 12.04LTS. Centos 6 was the easiest from a driver installation but the downside was that Centos does not supply BOINC in their distribution. BOINC from the BOINC website would not install because it had been compiled against a different distro using different library structures. You do have the option of downloading BOINC source code and installing on Centos and this would fix the problem. But ….
Using a combination of procedural steps from both the Fedora and Centos installation readmes I came across I was able to get the NVIDIA drivers installed on FC 17. See the side bar: “Seti@home, Fedora 17, BOINC…” for detailed installation instructions on Fedora 17. This is my attempt to identify exactly was is needed for a successful installation and how to get there.
These procedures might also apply to other Linux distros, but the file naming convention and file locations are different on Fedora 17 so that will require adjustments. But the basic step/procedures I think would apply.
None of what I provide is original but taken/borrowed from multiple websites. I have posted most of these websites in a “USEFUL LINKS” section of the detailed install. You will be visiting some of these sites to download various components and will encounter much of what you read here and in the detailed procedure on those sites.
ICU (do you see me?) completed
Today I finished ICU (a Perl/TK inSSIder look alike). See “ICU” under “Linux Tools” in sidebar.
Hardware upgrade
I moved to new server hardware which required an install of a 64 bit OS and a resinstall/configuration/compile of most of the software I run. I am still finding “missed” requirements and address them as they occur. You too might find issues like broken links. Not all the webpages have been restored but I am working it.
I have also upgraded the blog software and added a new look (theme) as well as reworked the way pages display in this blog. Before, all posts were logged to the default page (the page you are currently looking at). Now only the last post with a “previous entry” link for others in this default category will be displayed. All others posts now display only under their assigned categories listed in the right sidebar.
