I recently upgraded to Fedora 15, and I'm very put off by the selection of window managers, and their stability I'm a long time Gnome2 user. Gnome has a nice set of features, it works well, its stable, /cheer for the gnome team. Gnome3, which is included in Fedora 15, is horrid. Probably because it's still young. Gnome 3, with gnome shell does not work at all on my desktop at work because of how my displays are configured (4 displays, spanning 2 cards with xinerama, which kills 3d-support) and while it works, technically, on my laptop, it does NOT work reliabl
Snapped this pic this morning before heading off to work. My wife's pile of flip-flops. And this isnt all, these are just the ones she keeps handy for letting the dogs out...
This write-up is incomplete, but it has some useful information about my first attempt at ganeti. I'll be attempting this install on another set of machines in the near future, and i'll post another blog entry.
I'm a system administrtor, I started out as a hacker, a tinkerer, and a curious sort. No, I've never stolen your credit card number from Bob's pet mart's web site, and i've never defaced whitehouse.gov. I'm using hacker in a more positive light. Something you'll find I'm adamant about.
I was doing some thinking this morning while on my hour long commute. Thinking about old times, and old friends. High school, when I was in high school, I went to a technical school, we had this project. A hand full of us were picked to physically wire the school for cat5. It wasn't a huge building, 5 of us were picked. Once the cable was laid, we brought on 5 more students, and we built or upgraded 170 pc's.
I'm just reading about this now, but apparently Yesterday, 4/22/2011, morning a network event took severely hindered Amazon's EC2 cloud. According to an article I found on Internetnews.com Amazon is blaming the outage on storage issues caused by a network event.
A report form amazon said:
VDI, or Virtual Desktop Infrastructure is one of those new IT buzzwords. VMWare does it, Citrix Xen Does it, a few others do it. RedHat does it (or, is in the process of doing it) as well.
This is a simple one, but I've not used it much before today.
You can use lsof on a linux box to find out what's connected to what over the network.
In this case, we'd implemented a new ldap server, and it's address had changed, I was attempting to determine what was still connecting to the old ldap server on a given linux system.
I have an HTC Incredible, bought it a few months ago, and shortly thereafter rooted it.
I used the Unrevoked one-click root tool. Just plug in your HTC droid via USB, set it to Sync mode, and fire up the app. It'll install ClockworkMod Recovery, and sets S-OFF, and enables superuser access. You can then install root apps, like wireles tethering, Titanium backup, and a number of other things. One great thing that Clockwork gives you, is the ability to run NAND backups of your current running ROM, and the ability to install other ROMS. Which is perfect!
So I'm working on regisgtering 100+ RHEL systems to a new RHN Satellite server. The following command line for loop magic mad this a snap, thought it was worth publishing.
"The Cloud" or "Cloud Computing" are some of the latest buzz words in the industry. The definition of either of these terms is... well.. cloudy. The basic idea is that your applications are virtualized across a global network of hypervisors. Not too dis-similar from the VM Clusters run at the institution that I work at, just on a much larger scale.
