Handy One-Liner for a Comma-Separated List of Pingdom IPs
Do you use Pingdom to monitor your server's uptime? Do you also use a firewall management tool to make it easier to manage iptables or another firewall, but don't allow your server to respond to ping for whatever reason? Pingdom makes a list of their current IP's available via an RSS feed on their site. But that list is separated by new lines, and some tools would rather you give them a comma-separated list. The wget and perl parts were found here.
Centralizing Logs with Lumberjack, Logstash, and Elasticsearch
We've all done it. When we needed to find something in a log, we just did a cat or a tail and piped it to grep. Maybe we told grep to also show us X lines before and after what it found. That works fine and dandy when you've got just one or two servers. But what about 30, or 300, or 3000?

Upcoming Classes to Help Your Business Succeed Online
Once again this year, I'm instructing a few classes through Western Technology Center aimed at helping your succeed online.

Preinstalling Your SSH Key on a Rackspace Cloud Server
One big complaint I hear from people used to Amazon AWS, HP Cloud, and other providers that let you store keypairs in their dashboard is that Rackspace lacks such a feature. While that feature is missing from the dashboard, its not impossible to deploy a server with your SSH keys pre-installed. In fact, it's easy if you're using their API.
