Devices you already own can be greener

Many companies are investing in the green market by creating energy efficient appliances, but those new devices tend to be pricey. Besides, why replace something that still works? Tenrehte Technologies, a start-up located in Rochester, NY and Austin, TX, would like to help people reduce the power consumption of products they already own.

PICOwatt, Tenrehte's first product, allows consumers to turn off any appliance with just a few clicks. Appliances plugged into the device are controlled by the consumer via Wi-Fi. Energy usage, timers, and power are all controlled with a smartphone or computer. For example, instead of using … Read more

Create a bootable clone of your hard drive

SuperDuper is a popular, powerful, and easy-to-use app for quickly creating a fully bootable backup (or "clone") of your hard drive, whether you're recovering from a mishap or just migrating between machines. Even better, SuperDuper is free if you don't want to pay for its more advanced features, including scheduling, scripting, and "Smart Updates" (which save you time by making incremental updates to backups using only recent changes).

SuperDuper's interface sets out to make backups painless. Less technical users will love its friendly, plain-language approach--for example, explicitly explaining what will happen when you … Read more

Hands-on with DJ Hero

As the music games genre overflows with add-on packs for Guitar Hero and Rock Band (and too many plastic guitar variations to count), consumers might be feeling a little gun-shy about adding a turntable to the mix. Smartly, however, Activision has countered the skepticism by adding what might be the best video game soundtrack of all time to DJ Hero.

Ninety-three tracks (double the amount on The Beatles: Rock Band) of unique mashups and remixes from some of the world's most renowned DJs are not only great listening, but each one takes two excellent source songs to make music with. That's actually 186 songs floating around somewhere in this game.

Scott: The turntable in DJ Hero almost feels like an afterthought compared with the track selection, but it's solid and thankfully compact, with a free-spinning platter that's extremely smooth. The plastic buttons, crossfader, and other knobs feel a little jiggly, but the rubber feet beneath will make sure the controller stays put on a table.

To make music in DJ Hero, a very similar-looking "notes approaching" interface is repurposed to resemble a spinning record. Three different note-tracks are controlled by pressing colored buttons on the plastic turntable, just like Guitar Hero or Rock Band. You can also scratch the notes by pressing and turning at the same time.

On the left side of the controller, the crossfader is activated during certain zig-zaggy cues in the track, and alternates the two tracks. Above that is a "euphoria" button that is DJ Hero's version of "star power." Beside that is also a knob that either controls pitch effects during some sections, or selects sound effects in another portion of gameplay. As you can imagine, it starts to get complicated. DJ Hero might have one knob too many, but it adds to the feel of deck manipulation, and keeps your hands pretty busy. The end result--awesome hip-hop--is worth the effort.

Months ago, we were skeptical about DJ Hero--we worried that it was shameless music game exploitation. We were wrong. The effort has been exceptional, and that level of incredible musical talent should earn DJ Hero serious consideration this fall, perhaps even over the latest Rock Band and Guitar Hero entries.

Jeff: The real star of DJ Hero is without a doubt the music. The game boasts 93 mashup tracks that are sure to appeal to music tastes of all kinds with some of the most renowned DJs in the business lending their talents to the game.

So how does it play? DJ Hero is an interesting beast as its wireless turntable controller must be played on flat surface. We found success laying it on an ottoman while sitting on a couch behind it. For the most part, the tapping, crossfading, and scratching works, but you may have a problem with the button closest to the center of the faux record. Since it's anchored so closely to the center, it's tougher to scratch than the outer buttons. Regardless of how you orientate the controller, that last button may give you a problem.

The crossfader is also tough to master as its center position is not as easy to detect as you might think. During songs you'll have to switch it left and right, but we wish the center was more noticeable just by feeling its position--a definitive notch here would have helped.

DJ Hero may have less of an appeal to the more mainstream Guitar Hero franchise fan; it's a different demographic that this game is trying to reach. That combined with the intimidation of finding room for yet another plastic accessory and its $120 price tag may turn off prospective buyers.

Dan: We've spoken before about the threat of guitar game fatigue, with semiannual installments of music games vying for consumer's increasingly stretched dollars. Successfully injecting a little new life into the genre, DJ Hero is the biggest sea change in music games since the addition of drum kits. … Read more

How to set up an iPod Nano

In recent statements, Apple reports 50 percent of new iPod sales are going to customers who are buying their very first iPod. That means millions of people are setting up an iPod for the first time. Personally, I'm a little scared for them.

The iPod celebrates its 8th birthday this month, and it has come a long way. What started out purely as a digital music player has evolved into a video-recording, movie-renting, fitness-tracking, do-everything device. For first-time users, I can imagine the experience of setting up a new iPod is as overwhelming as it is exciting.

Keeps Windows 7 clean with System Mechanic 9

You get a new computer and it runs great. However, after a while, things start to get more and more sluggish. This is true for all operating systems, including those running the all new and shiny Windows 7.

That is because, other than user errors (such as misuse, viruses, spyware, accidental file deletion, harmful changes to the Registry and system settings, and so on), the OS doesn't take good care of itself. It collects and store junks from the Internet. It doesn't completely remove remnants of unwanted applications. Its Registry keeps getting more and more bloated with residual settings, and so on and so forth. All of these result in system clutter that over time slows down the machine.

This is when a cleanup software, like System Mechanic from Iolo, comes in handy.

I tried version 9.0.3 of the software recently, as it's the first I found that works with Windows 7 64-bit (the software itself is 32-bit, however) and it seemed to work well, though not perfectly.… Read more

Frugality rules among Cleantech Open finalists

California regional finalists for the Cleantech Open were announced Wednesday.

Think of the Cleantech Open, which started in 2006, as a Western divisions-only March Madness for environmental techies looking for funding. Contestants initially compete against each other in three Western U.S. regions: California, Rocky Mountain, and Pacific Northwest. Since its inception, the contest has garnered more than $125 million in funding for its contestants, according to Cleantech. It's also helped companies like Cool Earth Solar, and GreenVolts get noticed.

This year the California region judges had an initial pool of 278 teams, which it narrowed down to 49 … Read more

Google SketchUp 'plug-in' offers energy analysis

An updated software tool combines energy-use evaluation with Google's 3D-modeling program to help improve building design in its early stages.

OpenStudio, a free, open-source tool introduced last year, now integrates EnergyPlus building analysis with Google SketchUp, the National Renewable Energy Laboratory announced this week.

"OpenStudio is lauded around our office as one of the most complicated plug-ins ever written for SketchUp," Christopher Cronin, Google's strategist for SketchUp, said in a statement.

While Google may see OpenStudio as a plug-in for SketchUp, OpenStudio's creators may instead see SketchUp as an add-on to its simulation program.
