If you administer a large SGE system or a small one with very high rates of job throughput then you are already familiar with the importance of the spooling subsystem and the decisions that need to be made regarding what methods to implement. I've long been a public fan of classic spooling on clusters with less than 100 nodes and classic tends to be the standard spooling method we choose on new cluster deployments in our industry.

For example, as part of my morning information routine, I go through my Gist dashboard. This is a list of all the new information that Gist has found from a wide variety of data sources about people and companies in my social network. It derives the social network from my email inbox, integrates it with my Facebook, LinkedIn, and Twitter social graphs, and then presents it to me in a way that is prioritized by what it thinks I find most interesting. The level of relevance to me is amazing now that I’ve had it running for a few months. While Gist is still in closed beta, if you want an invite just email me.

"How would you explain LDAP to a sysadmin who'd've heard of it, but not interacted with it before."

you can modify the ksdevice= variable a couple of ways

This is a very very black modification of my slickness theme.

However, sometimes I need a lot more information than just this. I need to know which command was executed at what time.

Michael Halligan said the other day on twitter, “I feel that any sysadmin today who isn’t learning Ruby and either Chef or Puppet will be unemployed in 5 years”.

check_dell_warranty will use SNMP, omreport, smbios or dmidecode to grab the system serial number, it will then make a query to Dell's website, parse the results, and print out a return.
