Inkless Printer generates images by making micro-holes

The good researchers at Missouri University of Science and Technology are hard at work to end our printer-ink woes. Since, the printer ink is very expensive, many alternatives are being researched by the team at Missouri Tech. An inkless printer that works by perforating special paper with thousands of microscopic holes in it. However, in order to share it, it has to be done through a peer electron microscope as it works on a microscopic level. The paper that is used is just 170 nanometers thick and made up of two layers of silver separated by a layer of silica in between. Images are produced by drilling microscopic holes into the material’s top layer of silver and then shining a light through them. By varying the location, density, and size of all those tiny holes, different colors are produced as light shines through and is absorbed and reflected in different ways. The quality of the images still has to be honed, but they are competent enough as of yet. That said, Major Printer companies like HP, Canon and Epson are not looking into this kind of research for commercial printers.

Powerful words from Steve Jobs on his sick bed

Powerful message. Steve Jobs’ Last Words - I reached the pinnacle of success in the business world. In others’ eyes, my life is an epitome of success. However, aside from work, I have little joy. In the end, wealth is only a fact of life that I am accustomed to. At this moment, lying on the sick bed and recalling my whole life, I realize that all the recognition and wealth that I took so much pride in, have paled and become meaningless in the face of impending death.

Non-stop pursuing of wealth will only turn a person into a twisted being, just l...

iTunes Connect is down!

Something is wrong in Cupertino. A number of developers today turned to Twitter to complain that iTunes Connect, a hub for iOS and Mac software makers, was logging them into the wrong accounts. The service appears to be matching log-ins with the wrong accounts, showing apps and usernames from completely different people. When developers try to access one of the apps, they receive an error message leading them back to their own account. iTunes Connect has since been taken offline as Apple’s engineers presumably set off to fix the problem. We’ve contacted Apple and will update if we hear back. Culled from: The Next Web
