I’ve been working with Docker a good bit and have updated my list of tools.  Here’s a quick dump of where I am in the design of the infrastructure. collectd will be used to monitor cgroup statistics.  This necessitates compiling all or part of collectd — the current packages do not contain the cgroup plugin.

I’ve been interested in Linux Containers for quite a while; I think that they have their sweet spot where they are better than virtual instances — in particular they require less resources. I am working on a framework to use linux containers for on-demand computing — increasing or decreasing instances of applications as...

Prior to JBoss 5, the jboss-all-client.jar was pretty much all you needed. However, the JBoss 5 Getting Started Guide states the following: The client/jbossall-client.jar library that used to bundle the majority of jboss client libraries, is now referencing them instead through the Class-Path manifest entry. This allows swapping included...

Torquebox and Cygwin don’t work as nicely together as one might hope. That said, here are a couple of findings: In order to deploy, you need to set the $JBOSS_HOME with the Windows path.  You can do this via export JBOSS_PATH=`cygpath -w PATH_TO_JBOSS`. Additionally, the JRUBY_HOME needs to be a windows path as well.   Otherwise you will...
