How to Clean Your Gear
So, someone has spilled beer on your gear, or it's gotten so gummed up with tar and gunk that it's not working anymore. What do you do?
First, if the offender is a liquid, cut the power immediately. If the unit has batteries, pop them out. If it's plugged into the mains, pull the plug. The sooner you do this, the more likely you are to save the unit. Once this is done, you can proceed on a non-emergency basis.
Second, get yourself some deionized water. It's important that you use completely fresh water that's been filtered by deionization, rather than by any other process. This removes all of the electrical potentiality from the water (as well as the electrolytes), so it's safe to use to clean your gear.
Third, disassemble the equipment and bathe all of the affected parts in the water. Scrub (with a clean, static-free cloth) any tars, residues, sugars or anything else off the gear.
Fourth, seal each piece in a ziplock bag or airtight container with either uncooked rice or (preferably) silica gel to dry. Leave it there for several days.
Finally, reassemble the gear, taking care not to subject it to static discharge.
At this point, so long as you've put everything together properly, your gear should once again be in perfect working order, unless something fried during those first few seconds. This procedure works equally well for mixing boards, amplifiers, laptop computers, hard drives and rack gear.

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
