How to clean a computer keyboard

Clean Up Your Dirty Ol’ Keyboard!

I was typing another article on my work PC the other day, and I noticed that it had some crumb-like things underneath or between some keys. When I looked closely, I could also see traces of oil where my fingertips had been mere seconds earlier. I instantly knew what I had to do: clean up my keyboard, and then maybe write an article about it.

The keyboard is perhaps the most-used computer peripheral. Of course, you can make a case for the optical mouse as well, but the keyboard generally sees more action because most people use computers to type stuff in. With many moving parts (the keys) and those recesses between them, the keyboard is a hot zone for dirt, dust, and crumbs to fall into. Over time, they can accumulate, generally mucking up your keyboard.

To effectively clean your keyboard, you’ll need some spare cloth or some of those fancy microfiber cleaning cloths. Make sure you have any cleaning implements you want to use at the ready.

First off, unplug the keyboard from your computer. This will make your cleaning task easier since you can move the keyboard around freely without having to worry about the cord.

Next, shake the keyboard moderately both upright and upside down. This will help shake off dust and other particles nestled between the keys. If you see some particles or crumbs that are hard to shake off the recesses of your keyboard, try blowing hard on it or use compressed air to really get those things out. You can also use a brush to sweep away the crumbs.

Once you’ve gotten the flakes and crumbs out, you can now clean the surfaces of the keyboard using your cleaning cloth. Make sure you make the cleaning cloth damp so that you can remove the oil or other substances that are stuck to your keys and keyboard frame.

Use another piece of cloth and gently wipe the surface of the keyboard so that it will dry faster. Plug your keyboard back into its slot in the CPU and voila—you’ve got a keyboard that is as good as new.

Make sure you regularly clean your keyboard. Not only will this help give you longer service life out of your computer peripherals, it will also prevent any insects from making a mess in your keyboard. Who knows, a clean keyboard might be just the kick you need to get started on that paper or report.

Get Some Android Love for Your Netbook or Desktop

We’ve discussed Google’s Android operating system a few posts ago. Now we’ll tell you how you can try out the OS yourself. This works best if you have a laptop or netbook or desktop lying around with some extra space and without an OS. Perhaps you went for the bargain netbook with no pre-installed OEM Windows. Maybe you want to do away with the clutter and install something light for your computer to run on. Perhaps you really just want to tinker with the OS.

Well, be our guest. Here is the step-by-step guide through which you can install Android on your computer.

Here’s what you’ll need for Operation Android: a Netbook or laptop or PC, a USB flash drive or memory card with at least 256 Megabytes free or a blank CD/DVD (most netbooks aren’t equipped with CD or DVD drives, so you’ll need flash drives for those. Even if your lappy or PC has one, why waste a perfectly good blank disc?), and a fairly-fast Internet connection. You might also want to sniff around the Web and see if your machine’s processor is supported.

To start, you’ll need to download Android. Go to http://www.android-x86.org/download and download the latest stable release in image file format. In this case, it’s just version 1.6 Donut. Sadly, if you’re looking for 2.2 Froyo or even 2.1 Eclair, you won’t be able to test drive those versions just yet.

Download the .img file if you’re going to go the USB route, and the .iso file for discs. You can also use the .iso file with the Unetbootin application and it will extract the .iso to your USB stick.

With the Android OS loaded on your flash drive or burned to your CD or DVD, you can now reboot your laptop or PC. Enter the BIOS screen by pressing the respective key on your computer. There will usually be a prompt that shows what key you should press.

Once in BIOS, change the boot order of your computer to boot your USB stick or CD/DVD drive first. After booting, choose the option Live CD – Run Android x86 without Installion. There will be a short loading time that shows an MS-DOS-like prompt typing “Android” and then the Android boot screen should appear. After that, you can now see your new desktop in all its Android glory!

Bear in mind that you’re only running the Live CD version, so any new apps you install in a session won’t be there once you log out and log back in. Depending on your computer, some pieces of hardware might not be supported, like the camera or Wi-Fi. Still, this should be an excellent opportunity to see what’s with all the hype and judge for yourself how fast and responsive this mobile OS really is.

If you’re bolder, you can try installing it (though we don’t really recommend it) or using the Java-powered Android Emulator. That said, enjoy your Android experience!

Micro Blogging Wars Part 1: Why Plurk could be Better than Twitter

Micro-blogging has proliferated on the Internet for the past few years, with the popularity of sites like Tumblr, Plurk, Twitter, and even Facebook with its status updates that function much like micro-blog entries. Today, we will compare a couple of the more popular micro-blogging sites or tools, namely Plurk and Twitter. They share practically the same concept, only implementing them in different ways. The two services are both text-centric, which is the basis for the comparison.

Instead of going with how one stacks up against the other, we will be bringing points about how one is better compared to the other based on a specific criteria or aspect of the service. For today’s business, let’s go with why Plurk is better than Twitter. We will discuss why Twitter is better than Plurk on the next entry.

Timeline Layout

While both Plurk and Twitter sort entries chronologically, the Plurk Timeline looks and feels superior to us. Why? Because it gives you an idea of the time your friends posted their entries. You’ll see some posts bunched up together, and you will know that at such times, a lot of your friends are online and active.

Of course, one could argue that the Timeline could easily become messy and that Twitter looks much simpler and cleaner (especially when we talk about browsing through mobile devices). Still, the Timeline layout has a lot going for it: accessibility, appeal, and an all-encompassing view of posts.

Replies are More Accessible and Direct

Since each post or message in Plurk is displayed within the Timeline, you also see any and every reply made to those posts just by clicking on them. It is also easier to track new replies to your posts or replies to posts that you replied to, thanks to a notifier right in the lower right corner of the timeline. You can also see private posts that you can view.

There are also less celebrities to follow on Plurk. In that way, it becomes more personal because you most likely are reading posts of people you actually know. There would be no need for third-party applications just to keep the clutter organized.

Achievements and Unlockable Content

You can unlock some achievements that will be visible on your profile page. These achievements include stuff like having invited a certain number of friends, reaching a certain number of “fans”—people who add you to follow your posts—and reaching 100 karma.

Karma is a measure of your activity in Plurk. It increases with posts and the replies you make and receive. When you reach a certain level of karma, you will gain access to more smileys and emoticons that you can use for posting. Being able to change your screen name also depends on the amount of karma you have.

Plurk is lagging by quite a bit compared to Twitter in terms of popularity. Nevertheless, there is a reason many people still stay on this particular microblogging slash social networking site. Plurk has its own strengths to counteract its perceived weaknesses. Even with the continued rise of Twitter as the microblog of choice, Plurk retains its standing as a worthy competitor. Next, we will be discussing the advantages of using Twitter. Stay tuned!

Windows Phone 7

One of the most anticipated developments in recent months is Windows Phone 7, MicroSoft’s challenger in the highly-competitive mobile operating system wars. WP7 will no doubt have a hard time ahead, what with the sheer popularity of the Apple iPhone with its iOS and the hordes of devices equipped with Google’s Android OS (both of which we’ve already discussed in previous posts).

Windows Phone 7 will debut in October this year, and last week the final release version has already reached manufacturers. This means users will have WP7 phones in the palms of their hands in no time.

Among Windows Phone 7’s most notable characteristics is its high demand for top-tier specifications. These are hardware requirements that MicroSoft has given the manufacturers who wish to run the OS. The minimum requirements are, in no particular order:

-          a 1 GHz ARM v7 Cortex or Scorpion processor

-          at least 8 GB of Flash memory and 256 MB of RAM

-          a 5-megapixel camera (with flash)

-          capacitive multitouch screen with at least WVGA (800×480) resolution

-          hardware buttons on the unit with dedicated WP7 functions: Start, back, search, camera, volume up and down, and power/sleep

Those requirements meant that there would be basically no possible upgrades for those who bought phones fitted with the Windows Mobile OS. This is especially true because of the requirement of hardware buttons on the unit itself.

Many have praised the OS for its unique take on the user interface, an area that companies and consumers really put a premium on. There are also praises for the OS’s virtual keyboard design.

There are, however, a number of features that will be missing in the initial release version—something that consumers need to know before jumping right onto the bandwagon. These are copy & paste, limited multitasking, electronic compass (even though it was required of manufacturers), and the lack of browser support for HTML5, Flash, and Silverlight, among others.

MicroSoft has spent a lot of time making sure the UI and user experience are more than satisfactory. Still, it remains to be seen how this newcomer will hold up against the established heavyweights. We’ll get back to you in a month or two, right when WP7 phones make landfall in retailers around the globe. Watch out for that!

Five Business Application Ideas for the iPad and other Tablet Devices

With each passing day, more people turn to tablet devices like the highly-popular Apple iPad for many business processes. The possibilities are endless. Well, almost.

Here are some ideas that Fornongeeks.com thinks the iPad and similar tablets can be of service. Wait, scratch that—these are functions that these tablets can very much excel at!

Menu Apps

A few restaurants are already adopting the iPad for their new digital menus. Time to get rid of all those expensive printing costs for high-quality glossy paper, die-cut finishes, and the ever-popular spot lamination. Additionally, by having tablets as menus, customers are saved the trouble of having to browse every single detail when they can possibly just search for what they want in just a few swipes. Best of all, just think of all the trees that will be saved!

Catalog Apps

This is just as green as the previous item. No need for all those pages’ worth of item catalogs. Additionally, users can simply input a desired product range or even the exact specifications of the item they’re looking for and they’ll get near-instantaneous results. This will even help all the sales personnel who are having a hard time getting all those part numbers and SKU numbers around their heads.

Sheet Music / Lyrics Display Apps

Guitar tabs, piano scores, and all other sorts of musical pieces should be viewable via tablets. The UI can potentially be able to scroll within set intervals, or there can be an app that can detect the music being played and scroll over the sheet like a karaoke machine does with lyrics as you sing through it. Perhaps some people can even develop an app that can read when you get to the end of the sheet and then flip over to the next page.

Movies on the Go in Public Transport System Apps

Got a long flight to some exotic tropical getaway? Waiting for that Greyhound to finally leave the station? With the possibility of streaming media over a tablet’s internet connection, weary (and most likely bored) travelers can select a particular movie title and watch it on the go. Now, commuters and tourists won’t have to spend hours bearing with what’s showing on the flight or on the bus (if there’s any at all).

Virtual Library Apps

Tablet computers have the potential to make libraries obsolete. The iPad and the Amazon Kindle are already ushering in a new age of digital publishing by getting content such as newspapers and e-books straight to the reader, and it isn’t too impossible to have whole academic libraries stored in these kinds of devices. While scrolling through digital content will never replicate the feel of actually thumbing through old books and research material, everything becomes oh-so-easier.

Tablets own the headlines of today’s top tech sources, and it’s not hard to see why. There is tremendous upside and potential when we speak of this fledgling platform. With their maximized displays, handy form factor, and relative ease of use plus relative ease to set up, businesses can readily adapt certain processes in order to facilitate user experience and offer the cutting edge in service.
