Build Your Own Arcade Game Player and Relive the '80s!
Hacking a keyboard in four easy steps:
Take apart the keyboard, making sure not to damage the PCB.
Find the two sets of connectors on the PCB, and on a chart, label them X and Y.
Trace the very small, fine lines on the flexible plastic sheets to determine the X and Y coordinates for every key. No, really, I'm not kidding.
Solder wires onto each X and Y terminal, and use those wires to connect to the arcade controls.
Obtaining Legal ROMs
MAME ROMs are easily located for download on the Internet, but the legality of using those ROMs are questionable. There are a couple ways to ensure that you have the legal right to your ROMs.
Buy the actual motherboard from the original game. This may sound far fetched, but it's not too difficult to purchase broken arcade boards from either local coin-op vendors or on-line from eBay. Because you're just looking for the legal right to use the downloaded ROM, it doesn't really matter if the board is broken.
You can buy the X-Arcade keyboard, which comes with a handful of classic ROMs.
Check out arcadecontrols.com. There are some free, noncommercial games available for download and some more ideas regarding obtaining legal ROMs. It often is difficult to find whom to buy the rights from, even if you want to spend the cash.

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
