Why Everything Wireless is 2.4GHz

You live your life at 2.4GHz. Your router, your cordless phone, your Bluetooth earpiece, your baby monitor and your garage opener all love and live on this radio frequency, and no others. Why? The answer is in your kitchen.

What We’re Talking About
Before we charge too far ahead here, let’s run over the basics. Your house or apartment, or the coffee shop you’re sitting in now, is saturated with radio waves. Inconceivable numbers of them, in fact, vibrating forth from radio stations, TV stations, cellular towers, and the universe itself, into the space you inhabit. You’re being bombarded, constantly, with electromagnetic waves of all kind of frequencies, many of which have been encoded with specific information, whether it be a voice, a tone, or digital data. Hell, maybe even these very words.

On top of that, you’re surrounded by waves of your own creation. Inside your home are a dozen tiny little radio stations: your router, your cordless phone, your garage door opener. Anything you own that’s wireless, more or less. Friggin’ radio waves: they’re everywhere.

Current state of PC hardware:

AMD owns ATI.

AMD cpu’s give more cores and hertz and more value as well as more upgrade-ability but perform less per hertz than Intel’s and run hotter. But on processes with a lot of integer core usage, AMD wins out.

Intel’s quads compete with AMD’s six cores. Their duals compete with AMD triple cores. Further, their memory allocation is better and thus anything with high extension usage (photoshop, rendering, etc) or anything that uses a large amount of data (ripping, converting) is better with Intel

AMD/ATI released the DX11 series graphics far before Nvidia. Their cards are cooler and slightly more expensive. They are releasing a new series starting in October that should retake the performance crown.

Nvidia is behind with DX11, but fermi (400 series), while much hotter, outperforms ATI at the same price points. The reason they are behind is GPGPU. GPGPU is using the gpu as a general processing core. You can compile C and Fortran code to run on a Fermi chip now. For the consumer this hasn’t made much difference, but it probably will in the future.

Future: Intel will go from Nehalem to Sandy Bridge. The core technology isn’t changing that much nor is the naming scheme. But it should run even cooler. However, they are updating their sockets again and you will have to buy a new mobo to use a new CPU. Also they continue to upgrade their atom line but an out of order processor doesn’t seem likely next year.\

Give your eyes a break

If you spend a good part of your day using the computer, the 20-20-20 rule, that I recently learned recently from my doctor, might also help you relax your tired eyes.

The rule goes something like this.

The screen is bright and therefore, if you don’t blink your eyes as often as you should while working at the computer for long hours, you can have dry eyes sometimes even followed by redness.

To help you deal with this problem, the 20-20-20 rule suggest that after every 20 minutes, you (the computer user) should take a break for at least 20 seconds and look at objects that are 20 feet away from you.

Since it is nearly impossible for any computer users to remember that they have to take a break every 20 minutes, there are free software programs that can help you in your mission.

For instance, there’s a Windows utility called Eye Defender that sits in the system tray and, after a fixed interval, it will auto-run a visual training (see video below in full screen) for the eyes on your screen.
