The cost of hard drive space has been coming down over the last few years, with the introduction of technologies such as SATA it makes much more sense to have a portable external hard drive, today they can really picked up for less than $100, but there are a few point to think about when looking around for one.
Do you need it to be portable or ultra portable? Generally they come in two different physical sizes, 3.5” and 2.5” both have their good and bad points.
The 3.5” drive is quite bulky, plus it does require an extra power supply, but on a positive note it does come in larger sizes, presently up to 1tb. the 2.5” portable external drive is very portable, the later generation being only slightly bigger than the size of the physical drive in its case, this means it can easily fit in a pocket.
Another good point, the drive is powered from its connection to the computer, meaning no extra power supply. on the downside smaller external drives do have smaller MB size limits, currently around 300gb.
So do you really need hard drive MB space or hard drive physical size? the next point to look out for is the interface, you really have a choice of 2 types of interface USB or fire Wire, both USB and fire Wire come in different flavors or specifications, with USB make sure your computer and the portable external hard drive are both USB 2, this is around 10 times faster than USB1.
Fire Wire although the later types are faster than USB2, the faster interfaces are pretty much limited to Macintosh computers and generally not pc’s.
If you’re not sure if a computer is USB 1 or 2 a simple method is to plug a USB2 device in and simply wait for the message you have plugged a high speed device into a low speed port, which means you have a low speed USB 1 port on your computer. if that’s the case all is not lost, if you have desktop computer you can simply add a USB2 PCI card , or for a laptop a PCMCIA USB2 card.
If you’d like something a bit more than a simple external hard drive how about a LAN server? with this you can basically share it between many different computers.

The Epson Stylus Photo R2000 ($499.99 direct) is, for the moment at least, the least expensive of Epson’s high-end, near-dedicated photo printers, defined as printers that are meant primarily for photos and graphics, even though you could use them for office tasks if you had to. like other printers in the category, it offers speed, output quality, and features suitable for a professional photographer or graphic artist. in this case, though, the price is low enough to be attractive to serious amateurs as well, a combination that makes it an Editors’ Choice.
The R2000 is significantly less expensive than even the two next steps up in Epson’s line—the Editors’ Choice Epson Stylus Photo R2880 ($799.99 direct, 4.5 stars) and the Editors’ Choice Epson Stylus Photo R3000 ($849.99 direct, 4.5 stars). Surprisingly, though, it offers a similar set of key features, starting with paper handling.
The Basics like both of its more expensive siblings, the R2000 can print on cut sheets as large as 13 by 19 inches, print at up to 13 by 44 inches using roll paper, and print on printable optical discs. it can also take advantage of the same set of fine art papers that Epson sells for the R2880 and R3000, in addition to more common paper stock, and can even handle media up to 1.3 mm thick using its front-loading paper path.
The R2000 lacks such niceties as the color LCD control panel and the higher capacity ink cartridges you’ll find in the R3000. however, like the R3000, it offers Ethernet and WiFi support (Epson recommends using 802.11n connections only), and it lets you install black cartridges for both matte and glossy paper at the same time, so you don’t have to switch cartridges when you switch paper. it also offers a PictBridge connector for printing directly from cameras.
One other thing the R2000 shares with the R3000, R2880, and, indeed, any printer that can feed 13- by 19-inch paper, is a big size, so that finding enough space for it can be a challenge. it measures 8.6 by 24.5 by 12.8 inches (HWD) with the paper trays closed or 16.5 by 24.5 by 31.4 inches with the trays fully open. in addition, you need to allow roughly 4 inches of additional clearance in back for feeding paper using the manual front feed. both the size and setup is typical for this class of inkjet.
Setup and Speed For my tests, I installed the printer on a system running windows Vista, using the Ethernet port to connect to a network. I timed it on our photo suite, using QualityLogic’s hardware and software for timing, at an average 53 seconds for a 4 by 6 and 1 minute 42 seconds for an 8 by 10.
The speeds are almost identical to the times we got for the R2880 and R3000, and faster than we’ve seen for most other printers in this category. the Canon Pixma Pro9500 mark II ($849.99 direct, 4 stars), for example, came in at only 2:35 for a 4 by 6 and 4:31 for an 8 by 10. Note that we don’t time 13- by 19-inch printing, because manually feeding the paper is a big part of the actual time.
Output Quality and Lifetime the R2000 uses a different set of inks than the R2880 and R3000. According to Epson, the different ink sets should make the most difference for black and white photos, but there are subtle differences in color output as well, and in my tests they were all in the R2880′s and R3000′s favor. the good news is that the key word in subtle differences is subtle. unless you’re thoroughly familiar with the way a particular image is supposed to look, or you look at output from both ink sets side by side, you’re not likely to notice it even if you have a trained eye.
Because of the ink set, the photo quality for the R2000 is just a touch below the absolute best quality you can find. however, both photo and graphic quality is far better than the vast majority of standard inkjets offer, and still in the same league as the absolute best. Text was also suitably high quality for professional graphics.
The photos also promise to last. As with any printer, the photo lifetime varies depending on paper type. Epson’s claimed range for Epson papers is 160 to 300 years for dark storage (as in an album) and from 52 to 80 years for paper exposed to air, depending on which paper you’re using.
Other Issues there are two potential issues for the R2000, but they are typical for this class of printer (I mentioned them for R3000 also). First, Epson doesn’t give a rated monthly duty cycle for the printer, which means there’s no way to know how much you can print per month without shortening the printer lifetime in terms of the total number of photos it will print. and second, Epson doesn’t quote a cost per photo at any given size, so you have no way to judge running costs against the competition.
Clearly, it would be preferable if Epson (and other manufacturers) would provide these numbers. Given that most near dedicated photo printers suffer from the same oversights, however, you can’t count these as serious strikes against the printer.
The Epson Stylus Photo R2000 offers a balance of speed, output quality, paper handling, features, and price that make it highly attractive. most of all, it’s unusually affordable for its level of output quality. For the moment at least, there is nothing else in its price class that even comes close to challenging it. and that makes it a clear Editors’ Choice.
Compare the Epson Stylus Photo R2000 with several other Photo Printers side by side.

In our world today, the quality of a personal computer is often measured only by its processor speed, memory capacity, and hard drive space and for gamers, the quality of the video card. sometimes, the computer monitor will grab some attention, especially if it has an LCD screen. Seldom, however, do we think of a computer by its power supply. And seldom do we give them an upgrade, even if we have upgraded each and every other computer component.
But when the power supply is damaged or stops working, we have to think about it, or we have no computer period. the only solution is a power supply replacement.
There are a lot of computer power supplies available in computer shops, so finding one should not be difficult. Replacing your power supply with a new unit should also be easy. the hard part is selecting the power supply that your computer needs. There are different kinds of power supplies and each has different specs. For your computer to work properly, it must be equipped with the right one.
There are two basic things to consider whenever you are buying a new power supply for your computer — power requirements and the power supply’s form factor.
Modern power supplies have power outputs that range from 200 watts to 500 watts. Before purchasing a new power supply, you must first know the amount of power that each of your computer’s components need. these power requirements can usually be found on the labels of the components themselves. by adding up these figures, you’ll have a good estimate of the power output your new power supply should have.
As a general rule, never buy a power supply with output ratings that are lower than your estimates. Neither should you buy those that have too high a power rating, as most of this power would simply be wasted.
The standard form factor used on most PC power supplies today is the ATX-form factor. Not all power supplies, however, use this standard. If you have an older PC, it must be using a power supply in the AT-form factor. There are also less common form factors today like the TFX and BTX form factors. Before purchasing a new power supply, identify first what form factor would fit on your PC or else there’ll be no way for you to use it.
Its been a year since Razer first debuted its BlackWidow Ultimate mechanical keyboard, and this August the peripheral manufacturer has released a new and improved version of its popular gaming keyboard, the Stealth Edition.
As its name would indicate, the “Stealth Edition” features the same tactile typing experience sans the old-school typewriter clacking noise. Razer has also thrown out the black glossy finish—a huge fingerprint magnet—and replaced it with a matte design. The Stealth comes in two versions: the Razer BlackWidow Ultimate Stealth Edition (a mouthful, I know); and the standard BlackWidow Stealth Edition. What’s the difference between the two keyboards? two extra features—backlit keys and anti-ghosting with up to six simultaneous key presses.
Differences aside, the two braided wired keyboards still share a slew of awesome gaming features like on-the-fly macro recording, five additional macro keys, multimedia controls, a helpful Windows Starter disable button, and Razer’s own configuration software for creating extensive macros. The side of the keyboard features a USB port, headphone jack, and mic jack.
The Razer BlackWidow Ultimate Stealth costs $139.99, which is $10 more than the original BlackWidow Ultimate keyboard, and the standard Stealth Edition costs $79.99.
Last week, meanwhile, Razer finally revealed the product behind its mysterious “PC Gaming is NOT Dead” Web site, which declared in a rather V for Vendetta tone that on August 26 the company would turn the PC gaming upside down. That product was the “Blade” gaming notebook, which the company said was the “World’s first true gaming laptop.”

LucidLogix Injects HyperFormance to Virtu Software for Faster, More Responsive Notebook and Desktop Gaming
Press Release Source: LucidLogix On Wednesday September 14, 2011, 3:00 am EDT
KFAR NETTER, Israel & SAN FRANCISCO–(BUSINESS WIRE)– LucidLogix demonstrated today for the first time at Intel Developer Forum 2011 (IDF) the injection of HyperFormance™ technology into its Virtu Universal GPU virtualization software for outstanding gaming responsiveness, visual quality and frame rates.
“Games are all about creating a suspension of disbelief and a more immersive overall lifelike experience,” said Offir Remez, president and founder of Lucid. “HyperFormance technology provides a more responsive game interaction together with a clean visual image, making for a more pleasurable experience.”
HyperFormance, found in the new model Virtu Universal MVP, boosts gaming responsiveness performance by intelligently reducing redundant rendering tasks in the flow between the CPU, GPU and the display. 3D games put the greatest demands on both the CPU and GPU. and as the race for higher performance on the PC and now in notebooks never ends, both CPUs and GPUs keep gaining performance. Despite more powerful microprocessors, display refresh rate remained fairly flat over the years, at 60-75Hz. the exception is found in 120Hz refresh rates for 3D stereo displays (used to produce 60 FPS for each eye). Lucid takes advantage of this disparity and eliminates redundant rendering tasks and predicts potential synchronization issues in the graphics delivery pipeline and intelligently removes and/or replaces them for better game control.
Called Virtu Universal MVP, the software includes the base features of Virtu Universal technology, which virtualizes integrated GPU and discrete GPU for best of breed functionality as well as features Virtual Vsync™ for no-compromise visual quality. with the added benefits of HyperFormance technology, Virtu Universal MVP improves game performance responsiveness in many ways:
- Boosts responsiveness to the game at any frame rate
- Improves gaming frame rates 30-70 percent
- Increases Vsync frame rates– up to 120 FPS and beyond
- Sharpens visual quality without tearing
Virtu Universal MVP is available to system platform manufacturers using Intel Sandy Bridge Z68/H67/H61, and other Intel integrated graphics, as well as many AMD processor-based PCs and notebooks. Virtu technology has been verified with hundreds of games and applications and can be found bundled with almost all of the world’s Intel Z68 motherboards from the leading brands.

Lucid Technologies has reinvented multi-core graphics with its Virtu GPU virtualization software. Lucid is a fabless SoC and software provider, headquartered in Kfar Netter, Israel with sales and marketing in Silicon Valley.

LOS ANGELES (AP) An FBI spokeswoman in Los Angeles says agents are investigating a series of computer hacking attacks on celebrities.
The FBI’s Laura Eimiller said Wednesday that dozens of celebrities had been targeted by hackers, who stole personal information from email and other computer accounts.
She declined to provide further details, but several websites including TMZ have identified one of the victims as Scarlett Johansson.
A message left with the actress’ spokeswoman was not immediately returned.
Choosing a power supply is one of the most important steps when building a customized computer. since the building of customized computers have risen in popularity due largely to the gaming community as well as computer enthusiasts, it is important to understand how to choose a power supply for the ensuing stroke of genius that is created as a portal to the Internet. Without the heartbeat of electricity, and a steady stream that can handle the power built into a custom computer, even the best designed customized computers fall into the land of permanent rest.
Linear and switching power supplies are options as well as the uninterrupted power supply variety. the choice comes down to what you need for your particular computer and the amount of voltage necessary to run your new source of pride and joy.
Linear power supply is seldom the answer for customized computer. These types of energy supply require very large transformers and are extremely heavy. unless you are a body building champion with a need to prove yourself, linear power is probably not what you want at approximately one pound per ampere. Add to that the necessity of large heat sinks to dissipate energy loss and an efficiency of about 50%, linear power options are simply too cumbersome and inefficient to meet the needs of most home computer building purposes.
Most enthusiasts choose something in the switching power supplies category since they want a computer-not a weight lifting championship. there is higher production costs involved, but these options are lighter weight and smaller-meaning they will fit in your house. Another advantage is that these power supplies are about 70-90% efficient. since the efficient running of your computer is generally the goal, this increase in efficiency has a big pull for power supply choice.
While this sounds confusing, it really isn’t. Switching power supplies use AC voltage-120V or 220V-which is generally what a house is equipped to handle anyway. there isn’t any sophisticated equipment that you have to have wired into your house for its use. the main difference in the power supply needed comes in choosing the power factor correction and not in changing your plugs and house wiring to be able to use a switching power supply.
You may, however, have to increase your breaker capacity if you already have too much depending upon them when you plug your newest creation in, but that is to be expected with anything you add that uses the electrical circuits available in the average home. Another necessity is protecting your computer from power surges with a properly designed surge protector. Otherwise, there isn’t much you have to do to prepare for your power supply choice.
If you are still confused, simply call up your local computer store and ask. many of the employees in the stores can help you decide and find what you need. Always consider asking a professional computer tech who has experiencing in networking and other hardware areas of computers for the added security of getting the correct information and helpful recommendations that can make your experience with powering your computer an enjoyable one.
