Most people are used to hearing about overclocking a computer in order to make it run faster in order to better run certain CPU-intensive applications (usually games). What most people probably haven’t heard of, or even want to try, is underclocking a computer. Underclocking might not do much for desktop computers, but could provide longer battery life and cooler running temperatures for laptops, and after all, who doesn’t want to get the most out of those skimpy laptop batteries.

Hard drives fail, sometimes without warning. Most people might not even realize their hard drive is failing until data starts becoming corrupted or the drive simply stops working altogether; however, there are some signs which can help you identify a faulty hard drive before it is too late, particular by listening to the sounds it makes. The Hitachi Hard Disk Drive Knowledge Base answers some of the important questions, but this particular article has sample sounds, in .WAV format, which can help you diagnose what a faulty hard drive will sound like. Remember that the base offense is a good defense, so be sure to back up your data regularly.

When I first heard about TagWorld, I wasn’t quite sure what it was because the name, to me, implied that it was yet another social bookmarking service. While TagWorld does offer bookmarking capabilities (but no import or export functionality as far as I can tell), it is much more than that offering a wide range of features which in many ways makes it seem more like MySpace, particularly with the recent addition of a music section to TagWorld.

Glide is a brand new service which launched about two days ago which allows users to easily upload images, documents, music and movie files, and more, as well as offering pretty good tools to manage e-mail, do a little bit of simple image editing, manage contacts, and a few other tools which you can learn about from the main page. The entire interface is done in Flash (I’m starting to see a trend this week…a lot of Flash!) which is nice, and while the toolset is easily accessible, some users may have trouble figuring out how everything works, probably because Glide does too much. There is a basic account which offers limited storage space, as well as an assortment of premium accounts for those of you looking for something a little some substantial. While I enjoyed testing out the service, I did not like that even for a free account, you need to enter credit card information.

We’ve discussed a few methods of using a GMail account for online file storage before, and like before I will warn you that this usage of the service goes against the Terms of Service (TOS) and Google may remove your account if you use it. Regardless, I came upon an interesting service called G2G which lets you upload files into your GMail account through its fairly clean interface. Unlike other similar services like XMail Hard Drive, by using G2G, your files are not kept private. This is because G2G is intended as a P2P application of sorts, letting you share your files with friends and family easily. Because any stranger can look at your files, they recommend that you create a second GMail account simply for the purpose of using it with G2G (and I’d say that’s a good idea, considering the TOS). Because it uses GMail’s servers, the service is pretty fast, but I wouldn’t count on it being up too long because of it.

As many of my close friends know, I love using the command line. I’m faster with a keyboard than a mouse, and I prefer to use the bash shell rather than a desktop environment on my Linux computers; however, the Web isn’t intended for people who like the command line. I recently found a tool called YubNub that accepts commands to perform certain actions. For example, you could type in g Beaches to do a Google search for beaches, or try stock GOOGL to see Google’s going stock, using Yahoo! Stocks. The cool thing about YubNub is that it lets you make your own commands to query things that you like. They also have a bash script, a Firefox plugin, a Dashboard widget, and many other ways of interacting with YubNub without going to the normal site. Command line lovers rejoice!

The iPod has a nice, large hard drive in it, so many people (myself included) like to store certain important data on them, just to keep a backup in case a computer’s hard drive fails. While this is a quick and easy way to back up documents, it’s not necessarily the safest way to store data, fortunately, I found a great guide on securing the sensitive data on your iPod. The process requires that you have a Mac, as you need to use the Disk Utility built into OSX, but this could certainly be adapted for other operating systems with the right tools. Using the Disk Utility, you’ll be able to create a password-protected disk image which you can then mount to retrieve your data. Get all the details over at NonStopMac.com.
