WiGig routers now on the horizon

Posted on January 15, 2013

wigig The IEEE Standards Association has recently approved a new wireless Internet technology known as WiGig (that’s 802.11ad to you technophiles out there).

What makes this such big news is the blazing fast speeds at which WiGig wireless routers and other networking equipment will be able to transfer data over a Wi-Fi connection. The newly approved WiGig standard is theoretically capable of wirelessly transferring data at the mind-boggling rate of 7 Gbps, a speed that will make the Wireless N speeds that we currently use seem like a snail’s pace.

How to access a Shell Prompt on a Chromebook

Posted on January 15, 2013

Google’s Chrome operating system is billed as the OS that moves the computing experience into the “cloud”, but there is still an easy way to access a Command Line and Shell Prompt: Simply press the CTRL+ALT+T keyboard combination to get to the command line, then type Shell to get a shell prompt.

Most users would be well advised to stay away from the Chrome command line since a misstep could seriously break your Chrome installation. But if you enjoy tinkering and don’t mind taking a risk, have at it!

Posted on January 14, 2013

Have you ever bought an item, took it home, opened up the box and stashed the user manual away in a “safe place”, only to not be able to find it when you needed it? Yeah, me too. I wish I had known about a great site called ManualsOnline.com!

ManualsOnline.com has over 300,000 user manuals available for download right to your PC, for free. Their catalog includes manuals for virtually everything ranging from electronics to power tools to computers to appliances to lawn tractors to automobiles to…Well, you get the picture. At various times I have personally downloaded manuals for a couple of computers, my Samsung smart phone and my Husqvarna lawn tractor.

If the manual you’re looking for is in their catalog (and it probably is), finding it is easy. Simply browse the category of your item by brand and model number, or if you’re really in a hurry you can just type the model number into the Search box.

While this isn’t one of those sites that you’ll visit every day, when you do need it you’ll find it indispensable. I keep it safely tucked away in my bookmarks!

Should you buy a used laptop?

Posted on January 14, 2013

As a general rule, I don’t recommend buying a used laptop computer. Why? There are several reasons:

1 – The prices of new budget laptops have dropped to the point where they can now be considered disposable items. Why pay $200 for a used laptop that might have all kinds of hidden problems when you can pay $350 and get a brand new one with a warranty.

How to remove Java from your PC

Posted on January 13, 2013

java Java is a programming language that was used heavily by web developers back in the early days of the World Wide Web, but over the years it has largely been replaced by newer, safer and more powerful technologies.

A smattering of websites still use bits and pieces of Java code (not to be confused with Java Script) to accomplish certain tasks, but this is becoming ever more rare by the day.

Although Java is rarely used these days, most users will still find that it has been installed on their computers. This is now a huge problem because of a serious security hole in the Java core that has recently been discovered. You can read more about the flaw and why the Department of Homeland Security is recommending that Java be removed from all PCs right here if you’re interested.

If you’d rather skip the “why” and get straight to uninstalling Java from your computer, you’ll find instructions for doing so below. Be sure to remove all instances of Java found in the list of installed programs if you see more than one. [Read more…]
