rshall: A Tool for Managing Hosts in Parallel

leonvs's picture

Once you're managing more than a handful of UNIX/Linux boxes, a tool that lets you run commands on multiple hosts becomes pretty handy. When you're responsible for dozens or more, such a tool is an indispensable productivity enhancer. rshall makes it easy to run commands on many UNIX or Linux hosts on a network. The commands run in parallel, so output returns quickly and changes are nearly simultaneous. It's great for ad hoc information gathering, and for making changes in the absence of a centralized configuration management system.

If you use jQuery for web development you may encounter some bumps along the way. Save hours searching Internet forums and speed up development time with some basic tips and tricks for:

  • dependent lookups;
  • custom select dropdown options;
  • autocomplete text fields;
  • set value of hidden fields;
  • how to speed up web page loading.


For each of the bullet points, I will go through the basic well-documented approach, show why it does not work, then show the solution. Attendees will see the code and the webpage.

The list of topics include:

  • Cross Compiler Tools 
  • Communicating with the Processor Core
  • Writing a program to target memory
