Notes on installing Rocks Cluster Software…..

cluster, DCinema, ganglia, Rocks
- Front-end machine is a Dell 2950 with 2 x 1 GigE Broadcom ports onboard and one myricom 10GigE card.- Broadcom port #2 is disabled in BIOS- Broadcom port #1 is enabled and configured for external network (Internet)- Myricom 10 GigE card is hooked into a Foundry 8x10GigE switch that uplinks into our private Class B network. We own a portion of this network aa.bb.cc.130-190. Netmask is 255.255.255.192. The Foundry also downlinks to a Force10 48port Gig switch (with optional 10GigE port).

So when prompted during install I configure it as per…

TPMG visits Toronto Zoo…or…How I busted my camera shutter…

Flickr, Photography, Toronto, TPMG, Zoo
Well it finally happened yesterday. I busted the shutter curtain on my faithful Canon 1DMKII. Took a trip to Toronto Zoo and about an hour into the trip the shutter literally ripped (Damn Orangutans, I think one of them jinxed the camera :-)). I think the cooling (-15C outside) and heating (+25C inside) might have had something to do with it, plus the fact I was firing off at 8 frames/s. Anyways, I did get to fire off the couple of shots before camera went nuclear on me....More on flickr....

How to get Axis 207W Camera to work with Quicktime Streaming Server or Darwin Streaming Server

axis 207w, Darwin Streaming Server, OSX, osx Server, QTSS
I have to admit I have not touched DSS in a while, but the instructions below are generic enough that you should be able to alter it for your Darwin Streaming Server. For the purpose of this exercise I assume your Axis camera is setup for mpeg4 video and aac audio. I also further assume that you have a reachable IP address on the camera and know how to login to the web interface. First thing we want to do is make sure you have the uptodate firmware. As of this writing the newest firmware is 4.40.1. So make sure you have atleast that version as well.1) We need to login and change the RTSP daemon's timeout value. If we don't do this the server will stop sending packets out…
