As part of an amateur radio project I put together a network of video cameras and phones. 3 Raspian pis, one Arch pi, one raspbx (raspian). The pis with cams run olsrd to do mesh networking. The point of the test was to zero in on video performance across the mesh.
This kickstarter is now overfunded, but still an interesting Linux project.
Here is a public link to the presentation I gave today. I'll look at getting it into the new wiki as soon as possible.
All the imagery is open or shared source (another thing I'm into, open source artwork).
I'll be posting a webform for volunteers to sign up for the new architecture project soon. I estimate I'll have that ready before next months meeting, which I will set aside time to attend as well.
Thanks for tolerating my presentation!
The move is (more or less) complete to NoVa Labs new home. We will start meeting there on 8 November 2014.
NoVa Labs II
1916 Isaac Newton Square West
Reston, VA 20190
UPDATE: The list is close to being ready. We will migrate everyone and post the new address here.
I am working to move the mailing list. Stay tuned for an update. I apologize to those who can not get access or keep getting unsubscribed.
I just wanted to let anyone who wasn't aware that there is a LUG in Fredericksburg and I'll be presenting some basic photo-editing in GIMP at July's meeting.
This will be different than the content I showed at NOVALUG in January.
Check out the link for the July FredLUG MeetUP
I encourage you to join MeetUp and RSVP if you plan to attend.
On June 14, 2014 the monthly meeting of NOVALUG featured Peter Larsen, Senior Solutions Architect from Red Hat, speaking about OpenShift. Peter is a regular at NOVALUG, and cameraman for the NOVALUG Google Hangout for most presentations. He was performing a dress rehearsal for his talk at next week's South East Linux Fest in Charlotte, NC.
Peter explained that OpenShift is a user-friendly, easily-deployed platform as a service (PAAS). A little over two years ago the creators of Origin, the open source code for OpenShift, asked for feedback about their PAAS and feedback they got. Backed by Red Hat the product became a way to support a development community, negating the need for resources and the knowledge necessary to maintain an independent development platform.
I have a lot of respect for AMD because over the years they have come up with a number of true innovations, leaving Intel (sometimes the whole industry) to play catch-up for a bit. The x86-64 architecture (a.k.a. AMD64) provided backwards compatibility to the 32-bit x86 instruction set when Intel was ready to move on with Itanium. AMD followed up by baking the memory controller in the CPU. When paired with HyperTransport, this gave multiple CPU servers significant performance enhancements while still providing memory coherency.
Their current line of processors -- dubbed APUs -- merge the CPU and GPU into a single chip, trying to leverage that integration to better performance. Up until now, the two might live on the same silicon, but there was still a high wall between them. In the latest generation, codenamed Kaveri, AMD has merged the GPU and CPU in a tightly unified architecture called HSA.
On Saturday, 11 January 2014, the regular monthly meeting of NoVALug started, as usual, with an interactive monologue by Greg, bringing us up to speed on various current events topics. Most notable was the recent establishment of an association between Red Hat and CentOS. Greg filled us in on his take on the “What's in it for Red Hat?” side of the discussion, with input from Peter and others in the group. Then we got on to the main topic of the meeting – Inkscape.
