St. Patrick’s day is closing in on us quick. To any Irish, Catholic, or anyone who just likes pinching this day is one of our most fun days of the year.

So to get the most out of the green beer day, here’s 8 wallpapers to help brighten up our desktop.

Digg is arguably the most popular social news site on the web. The site covers topics ranging from Macs to Bush bashing with rarely anything in between. But beware oh new member, your article will likely be buried with the servers pounded by the overwhelming audience the beast withholds.

Before using Digg, you must remember these simple rules–both advanced and beginning users should consider all actions taken before it is too late.:

99% are pompous assholes
- Digg has something special about it that will grab anyone over the age of 16 by their balls (or nipples in case of the one female who uses Digg, whom is reportedly Kina Grannis). The witty commentary such as “Pffft”, “Wow” and “Amazing” with the every too often, but guaranteed to make you LOL “I nailed your mom.” is certain to make a grown man cry (sorry Kina, we aren’t entirely sure you are female, please get naked).

80% stolen from other social sites
- I love spending my day browsing through stories on Reddit, then browsing through them again the following day on Digg. It is something I find close to my heart, and will never give up. When I visit Reddit and see a popular story or picture I just know it will be on Digg the following day, and if it hasn’t been submitted I do it and smile knowing the people of Digg will love me for it.

The friends system sucks
- Friends o’ friends of mine, do you help or hurt me so? To get or not to get. I will never know.

The comment system is buzzerred
- Collapsed, not collapsed, the newest, the oldest, top votes or… wait, what? Did they fix it AGAIN? Hell…

Submitting during high traffic is Digg suicide
- Everyone wants their article to be front page Digg material, but when to submit? Diggers never sleep… and that is because they don’t breathe. It is probably because of the pizza and Ron Paul porn (a picture of Ron Paul with an iPod).

Alright, this list is a little late but eh… so what? It’s only the second month. So lets get started. Here are five products you should look out for in 2008.

5. The Enviro-T

A toilet with grass instead of water. What better way to cut down on water than not flushing? Just water the grass with your urine and use natural fertilizer.

4. Crapless Cows

Shitless cows. Yes, cows that don’t make pies. No crap, no methane. Well, except when they fart, the atmosphere might explode.

3. Paperless Books

Books that don’t need paper, or rather, books that aren’t read anyway.

2. Unwrapped Foods

Food without wrappers is a great way to save on plastic. Yeah, I know there are some foods that don’t come in plastic. But what about everything boxed or the wrapped meat in that stupid crap? Oh wait, that is plastic too. Either way, the food will look something like what the crapless cow would release if she could.

1. Clean power plants

Clean power plants are something we would all benefit greatly from. If only it were cheap enough and could provide enough power… hmm – pfff, like that will ever happen.

OLEDs have gained much popularity throughout the past year, but what does it stand for, what does it do and what is to come of it?

What is OLED?

Organic Light-Emitting Diode is any light emitting diode (LED) which emissive electroluminescent layer is composed of a film of organic compounds. Usually, it contains a polymer substance that allows an organic compound to be deposited. The compounds are deposited in rows and columns onto a flat carrier by a printing process, resulting in a matrix of pixels that can emit light of different colors.

The system can then be used for television screens, computer displays, portable system screens, or simply be used as a light bulb.Typical OLEDs emit less light per area than inorganic solid-state LEDs that are designed as a point-light source.

History of OLED

Bernanose and co-workers produced the first electroluminescence in the early 1950s by applying high-voltage alternating current field to crystalline thin films of acridine orange and quinacrine. In 1960, researchers at Dow Chemical developed AC-driven electroluminescent cells using doped anthracene.

In 1963, Weiss et al. First reported high conductivity in iodine-doped oxidized polypyrrole with a conductivity of 1 S/cm. As of 1974, the discovery was called “lost” and a melanin-based bistable switch with a high conductivity “ON” state. The material emitted a flash of light when switched.

In a 1977 paper, Shirakawa et al. Reported high conductivity in similarly oxidized and iodine-doped polyacetylene. The group subsequently won the 2000 Nobel Prize in Chemistry for the discovery and development of conductive organic polymers.

Future of OLED

• POLED – Patternable OLED. Uses a light or heat activated electroactive layer. A latent material is included in the layer so when it is activated, it becomes highly efficient as a hole injection layer, preparing LED and arbitrary patterns.
• FOLED – Flexible OLED. Any flexible OLED display. Thin enough to be rolled up like a poster and carried anywhere, even embedded in clothing.
• TOLED – Transparent OLED. A proprietary transparent contact to create displays that can be made to be top only emitting, bottom-only emitting, or both top and bottom emitting (transparent). TOLEDs can greatly improve contrast, making it easier to view displays in bright sunlight.
• SOLED – Stacked OLED. A novel pixel architecture that is based on stacking RGB subpixels on top of one another instead of next to one another—common in CRT and LCD. This improves display resolutions up to threefold and enhances full-color quality.
• IOLED – Inverted OLED. A bottom cathode that can be connected to the drain end of n-channel TFT especially for the low cost a-Si TFT backbone useful in manufacturing of AMOLED display, contrast to a conventional OLED which anode is placed on the substrate.
• WOLED – White OLED. White OLED has the potential to reach 150 lm/W. High powered, environmentally friendly, bright and uniform.
• PHOLED – Phosphorescent OLED. Phosphorescent OLED uses the principle of electrophosphorescence to convert up to 100% of the electrical energy in an OLED into light.

Advantages

• Can be printed onto any suitable substrate using an inkjet printer.
• Will cost significantly lower than LCD or plasma displays.
• A greater range of colors, brightness and viewing angle than LCDs, because OLED directly emits light. Colors appear correct and unshifted, even as the viewing angle approaches 90 degrees from normal. LCDs use a backlight and cannot show true black, while an “off” OLED element produces no light and consumes no power.
• Energy is wasted in LCDs because they require polarizers that filter out half of the light emitted by the backlight. Color filters in color LCDs filter out two-thirds of the light.
• OLEDs also have a faster response time than standard LCD screens. LCDs currently have a response time of 8-12 milliseconds whereas OLEDs can have less than 0.01ms.

Disadvantages

• Limited lifetime of organic materials.
• Blue OLED has a lifetime of 5,000 hours – lower than typical LCD, LED or PDP, currently around 60,000 hours. Nevertheless, Green PLEDs have been tested for 198,000 and Blue PLEDs 62,000 hours.
• Water in displays can damage or destroy the organic materials. Improved sealing is a must, and may limit longevity of the more flexible displays.
• Commercial developments have been limited by patents held by Eastman Kodak and other firms, requiring companies to acquire licenses.

Love is in the air! Or is that just the burrito I ate this afternoon? Well either way, Valentine’s day is approaching quickly. So what does that mean? You’ve guessed it! Free Valentine’s day wallpapers for everyone’s desktop. There’s even a special one for those who just hate Valentine’s. So here they are, 10 backgrounds for everyone’s desktop.

Valentine’s Day Backgrounds

And for those who hate Valentine’s Day

Brrr, it’s still cold outside. Maybe after V-Day we’ll have to go back to the winter wallpaper.

Until then, happy Valentine’s day!
