Twenty years ago, the NES changed the face of U.S. gaming. All this week, 1up.com has a series of features celebrating the anniversary of the Nintendo Entertainment System. From the site: "When the NES launched, America hated videogames. Well, sort of. The Atari 2600 had upset folks by flooding the market with bad software and, at first, retailers were reluctant to sell another system. But the NES was a hit, controlling a healthy 90 percent of the U.S. home videogame industry at the peak of its popularity."

Sobell is well known for several comprehensive and well-written volumes: A Practical Guide to Solaris; A Practical Guide to Red Hat Linux: Fedora Core and Red Hat Enterprise Linux (2nd ed.); and A Practical Guide to the Unix System (3rd ed.). It seems only natural for the author to follow these exceptional examples with yet another excellent book entitled A Practical Guide to Linux Commands, Editors, and Shell Programming . Read on for Norburyms' review.

Lord_of_Tech writes "CoolTechZone.com has reviewed Nokia's N90 cell phones that comes with 2 megapixel camera and a host of other features, and it costs a solid $900 per unit. "The minute you set your eyes on the N90, the first thing that springs to your mind is 'it looks a lot slimmer in photos...' but as you take it out of the packaging, you realize the heaviness of it. To be very clear at the outset though, this is not Nokia's attempt to produce as sleek a phone as the Motorola Razr. What it is designed to be is a feature packed phone that doesn't mind compromising on the ergonomics to pack in every last bit of functionality you could ever want on a camera phone."

An anonymous reader asks: "I've been asked to build a massive storage solution to scale from an initial threshold of 25TB to 1PB, primarily on commodity hardware and software. Based on my past experience and research, the commercial offerings for such a solution becomes cost prohibitive, and the budget for the solution is fairly small. Some the technologies that I've been scoping out are iSCSI, AoE and plain clustered/grid computers with JBOD (just a bunch of disks). Personally I'm more inclined on a grid cluster with 1GB interface where each node will have about 1-2TB of disk space and each node is based on a 'low' power consumption architecture. Next issue to tackle is finding a file system that could span across all the nodes and yet appear as a single volume to the application servers. At this point data redundancy is not a priority, however it will have to be addressed. My research has not yielded any viable open source alternative (unless Google releases GoogleFS) and I've researched into Lustre, xFS and PVFS. There some interesting commercial products such as the File Director from NeoPath Networks and a few others; however the cost is astronomical. I would like to know if any Slashdot readers have any experience in build out such a solution? Any help/idea(s) would be greatly appreciated!"

Greenie asks: "With fuel costs reaching record highs and more eco-friendly vehicles on the market than ever before, one has to ask, is it making a difference (yet)? NewEnough.com is an online retailer of new and surplus/wholesale motorcycle apparel based in West Texas. Recently, they posted a letter to the public on their website about how they've 'gone green,' and are offering incentives to their employees for switching to modern, fuel efficient vehicles (hybrid electric, diesel, bio-diesel...). While the specifics of their incentive program were not discussed, has anyone ever heard of larger companies offering a similar incentive program? According to Fortune.com, Wal-Mart is the largest employer in America. If Wal-Mart, McDonalds, UPS, GM, and Ford, the five companies that Fortune lists as having the most employees, all offered a similar incentive, more than 2,865,700 people would be eligible for incentive to go green. That could really start to make a difference for the environment. Now imagine the environmental benefit of every company in America making this same incentive offer..."

TossCobble asks: "With table-top roleplaying giant Wizards of the Coast (makers of Dungeons & Dragons, for those not in the know) broadcasting an open call for adventure designers and developers (including an entertaining developer test to gauge your own game-design talent and knowledge), I found myself once again considering the odd appeal of gaming for us programming types. It's interesting that something so free-form-ishly creative, socially dynamic, and utterly fantastical be fun for folks so grounded in logical programming. Of course, my theory is that gaming and programming actually have more in common than we might think. Tabletop roleplaying involves coming up with creative solutions to problems set in a clearly-defined ruleset, involve constant data-tracking and minor mathematical equations, and involve working together with small groups of people toward like-minded goals. Conversely, love of roleplaying can illustrate how important creativity is to good programming. What do you think?"
