Had an interesting go-around with WebDAV on a non-production test server with Apache2 and it seemed errors were almost random. There were a number of factors involved. First, I am testing for preparation of using multiple authors to update a website. WebDAV was the logical choice. Installing WedDAV was simple enough: load or enable modules …

Ubuntu 11 (Natty) on Beagleboard
I have no idea what messed up the microSD that had Ubuntu 10.10. I loaded up a new SD with the latest 11.04 image (zcat and dd) and that went pretty smoothly. Meanwhile, I decided to put Angstrom back on that corrupted DS card (worse case it wouldn’t work) withmy development PC (used Linux Mint presently). …

Beagleboard Ubuntu corrupted
I don’t know how it happened, but the Ubuntu 10.10 image and partitions I had on the Beagleboard got corrupted somehow. This used to work flawlessly. The little micro-SD card has been sitting in the slot of the board for about 9 months without being used. I wonder if static from the cables still attached …

Alfresco Backup & Restore
Alfresco has been working great for over a month now. One thing that had been nagging me was a successful backup and restore. I figured out the problem. I wanted to test on a practice machine, so not to brick the production site. That was the thorn in my side. I could create a new Alfresco …

Back to Sensing
Finally had some time to tinker again. This time working on the distance sensing function of eventual autonomic robot. I turned to a good ol’ Arduino for the physical IO. I got a Nano, and this is a sweet little microprocessor. All the functions of an Uno crammed into a little DIP from factor. For …

Dipping into Alfresco
For our office, I needed to incorporate another collaboration site for our team on a project. I had already used MS Sharepoint on a previous 3 year project. The interesting thing is the users could never warm up to Sharepoint on that project. Yes, Sharepoint is customizable, and I did a minimal amount with logo …

Blender gets a facelift
I have been using Blender since version 2.40 and have just gotten used to it. It was always way different from other graphic user interfaces (GUI), but features outweighed the awkwardness of navigating around. That has all changed with the almost released version 2.5X. I applaud the massive effort that went into the recoding of …

Beagleboard + Ubuntu 10.10…Sweet!
Things are just falling into place with this Beagleboard. The Ubuntu distro, although slow on installing packages is pretty damn robust. I have installed a bunch of packages without a hiccup. X11VNC works without any issues, and can access with ultraVNC without much screen lag. My UVC webcam (which can be seen in motion in …

New Tangent – Vortex86SX is History!
OK. Why spend so much time on a frankly, underpowered system board. Chalk it up to learning experience I guess. That Vortex86 may have been the cat’s pajamas (pulled that from nowhere) about 5-10 years ago with 300Mhz, but the lack of FPU or math coprocessor cripples it nowadays. Less operating systems will use it, …

Back to Linux
It has been awhile sinced I posted on this. My wife and I have been travelling and other projects have been sandwiched in between (like a whole diversion into circuit building and green energy, etc.). Anyway, I am back to hacking processor boards for robot integration. I am blogging about this because it may help …
