Dazzle your ears with KEF's X300A powered speakers

KEF's new X300A is a nifty desktop speaker, but it can also be used as a hi-fi or stereo home theater speakers. Granted, it's a bit pricey, but it sounds a lot better than say, a $699 Sonos Playbar. The X300A is a bona-fide high-end speaker system, so it sounds clearer and all around better than all the high-priced sound bars I've heard to date. After all, performance goals for most sound bars are pretty low, they just have to sound better than the iffy speakers built into TVs, and that's easy. Compared with a decent … Read more

Tip: Generate preview images for a collection of documents

Apple's QuickLook technology in OS X is a quick way to preview a document's contents before opening the document's handling program. QuickLook works by using a small plug-in that reads the document's format and generates a small PDF, HTML, or thumbnail preview of the document that is presented to you as a representation of its layout.

The ability for OS X to generate a preview of a document is convenient for QuickLook, but also may be handy for other uses as well. For example, MacFixIt reader Paul recently wrote in wondering how one might use this … Read more

Treat your Mac to World Backup Day

This Sunday, March 31, is World Backup Day, an independent initiative geared to raise awareness for data security and the importance of backing up computers and other devices that may contain important information. In light of this, you might want to consider taking the time to ensure that all of your systems are set up with a proper backup routine.

Backing up a system used to take a number of steps, and while there are many options and approaches for doing so, these days most devices include some sort of regular backup option that, if used, should be enough to … Read more

I've been no-contract since before T-Mobile made it cool

Oh, T-Mobile has gone no-contract? Yes, this is a big step for a major national carrier, but for me, it's whoop-de-doo. I've been no-contract for a year already. Plus, I have access to that big, juicy Verizon network that lets me make calls from the middle of the mountains in New Mexico. I'm a customer of Page Plus Cellular, a company that resells Verizon's data and talk-time network. I can quit anytime, with no fear of penalties.

Now that T-Mobile got all coy and dumped the contracts, it feels a bit to me like discovering a cool underground band and then having it hit the Billboard charts and hearing its best song on a McDonald's commercial. I can't really pull off a hipper-than-thou attitude about this, though. After all, I am making some sacrifices to ride the no-contract bandwagon. Here are the pros and cons as I see them. … Read more

Keep your Mac's screws from bolting

To upgrade your MacBook's RAM or hard drive, or otherwise work on its interior, you'll need to remove the bottom of the case. This is fairly simple to do with the appropriate screwdriver, but when you reassemble the system, even if you do so with expert precision, you may find that a screw is loose or even missing after a while.

The screws holding the bottom case together are fairly small, and while you can tighten them significantly, slight flexing of the bottom cover and chassis (unavoidable on portable systems) may work them loose over time. Additionally, since … Read more

How to manage transparencies in Preview

Transparency in images files can be quite convenient, especially if you need to place the same image over different backgrounds and want it to properly blend in. While having a white or other solid color background may help you view the image on the screen, with this setup if you embed it in a document with a different-color background then the white will stand out as an obtrusive rectangle.

To help reduce this, you can both manually remove backgrounds from images using Apple's Preview application or use a transparent canvas to compile images that already contain transparency.

Intel's upcoming 'Haswell' chip primed for gaming

Intel wants to make its future "Haswell" chip better than past generations of silicon at gaming and announced tools to make this happen at the Game Developers Conference today.

The world's largest chipmaker announced tools, known as extensions, for software developers that allow Intel's 4th generation Intel Core, aka Haswell, to process demanding special effects.

The first of these extensions, called PixelSync, allows programmers to more realistically render smoke, hair, windows, foliage, fences, and other complex geometry and natural phenomena, according to Intel.

"The artists working on Grid2 have been requesting this type of effect … Read more
