Chess Software for Linux
xboard can also be used to play chess via the Internet, which is an excellent way to find fun opponents of all skill levels.
In order to use xboard to play on an Internet chess server, first set up a SLIP/PPP connection, and then to get to the main free U.S. server, type:
xboard -ics -icshost freechess.org
This will connect you to the Free Internet Chess Server (FICS) through port 5000 and open an xboard display so that you are ready to both observe and play games. You will first need to log in, of course, and for this you should choose a handle to use as a guest until you think of one especially clever. To get a list of the games in progress, type:
gamesThen to test the interface, try typing:
obs 6to observe game 6 (assuming it exists). Your interface should work and you should see some pieces moving hither and thither; type “unobserve” when you've seen enough. The commands are quite simple, and the online documentation is thorough, but if you need help getting started you can ask other players in channel 1. A great many chess servers exist throughout the world, including Grandmaster Dzindzichashvili's chess.net, the (commercial) Internet Chess Club chessclub.com, and the main European free server eics.daimi.aau.dk; I imagine any of these would be happy to have new players.
Those of us who were made to suffer at the hands of Sargon in the days of the Commodore 64, tormented by the malicious characters of BattleChess, or politely dismantled by Chessmaster, now have the pleasure of choosing a variety of master strength programs to defeat us on our modern machines (the struggle to prove a consistent match to the ever-improving Crafty is being made into a movie, apparently to be called Searching for Holes in Crafty's Opening Book). However, today's computers also provide the frustrated chess player with relief that computers did not offer when the Commodore 64 was king: Internet chess, featuring human players, complete with mistakes and oversights that computers don't make anymore.

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
