Linux Journal Scripting Games?
For those of you who were unhappy that Script Frenzy was not about writing scripts but about writing...well...scripts, here is something to entertain you...The 2010 Scripting Guy Games! Huh? Windows? Um...
OK, yes the Scripting Guy Games are for Windows. But what if we did it for Linux. What sort of meaty script challenge could we come up with? Certainly something more challenging than determining the time or reading the registry. Here are some thoughts, with apologies to the Scripting Guy(s) for stealing their format.
Day 1: Beginner: Create a script to add a user to the system, provision their mail, IM, shares and home page.
Day 1: Advanced: Create a script to add a new system to the infrastructure, provision it and bring it on line without manual configuration.
Day 2: Beginner: Create a script to deprovision a departing user account, back up their files and move them off into storage.
Day 2: Advanced: Create a script to migrate an high-availability web cluster with MySQL database to new hardware, provisioned using the script from Day 1.
All four of these tasks were ones that I got hit with about two days into a job several years ago. The fun part was that we had to use basic shell commands. We did not have perl installed on the systems for security reasons, and we did not have ruby, or python or any of those wonderful tools. Just a bare bones installation of the kernel and bash (although feel free to use your shell of choice...ksh anyone?) - the tools needed to do the job at hand.
So, what do you think? Are you up to the challenge? Maybe we should set up a Scripting Gurus help and trade area on the site! Hmm...did I just hear our beloved webmistress whimper?
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
