Earn money at home with iwriter.com

iwriter.com is a genuine site, owned by a popular internet marketer Brad Callen for article seekers and freelance writers. Anyone can sign up from any country to make money by writing. Here requesters specify the keyword, category and special instructions for the article to be written. The total counting of the required article depends up on the requester and it would be of 150, 300, 500, 700 or 1000 words. The article seekers posted the projects in the categories like Health & fitness, Travel & leisure, Legal, Computer & technology, Finance, Arts and entertainment, Business etc.

The writer can choose the project from the list based on their interest and can start writing. The articles of 150 and 300 words should be completed within two hours and 3 hours time would be given to write a 500 words article. After finished writing within the given time, the writer should submit the article for approval. The requester of the submitted article goes through it and the article will be approved if it meets the requirement. Immediately the amount is credited to the writer’s account and if the article is rejected, no amount would be credited. Here the payment varies according to the number of words written, for 150 words- $1.01, for 300 words- $1.62, for 500 words- $2.42 and so on. If the earning reaches $20, the writer can withdraw the money through PayPal. When the writer submitted the article, it is checked with copyscape.com and sent for approval. So the written article must not be a copy content. If so, few warnings will be given and if it continues, the writer will be permanently banned from the site to write.

Not much skill is required to write the articles, but make sure the written article is free from grammatical & spelling mistakes. The writers can refer some sites while writing and must not copy the information from other websites. The requester gives rating for the written article (5stars, 4stars, 3stars, 2stars and 1star). The writers are needed to maintain good rating and if the rating goes beyond 2.5 stars or less, they won’t be allowed to write anymore. I am a homemaker and now earning a very good income with iwriter.com. I wrote more than 100 articles in the past 3 months, out of those only 15 were rejected and my rating is 3.9 stars. I hope my visitors can also earn money through iwiter.com. Also if you are a blog owner or need articles to submit in article directories site, you can get quality articles from iwriter.com at lower rates.

Hand-manipulated objects and transparent displays - the computer desktop of tomorrow?

 

 A see-through screen, digital 3D objects manipulated by hand, perspective adjustments according to the user's viewing angle - these are the core features of a prototype computer desktop user interface created by Microsoft's Applied Sciences Group. The prototype uses a "unique" Samsung transparent OLED display through which the user can see their own hands to manipulate 3D objects which appear to be behind the screen.

       

A demo video appears to show a working prototype of a computer markedly different from those we use today. Yes it includes a familiar keyboard and trackpad - but these are placed behind the OLED display. The user simply lifts their hands from these input devices to manipulate on-screen (or more accurately behind-screen) objects, such as selecting a file or window.

The video shows the interface in action with a series of program windows stacked behind one another, with the user selecting the desired program by hand, using the depth of the workspace.

Similar actions are shown to manipulate 3D objects - an exciting prospect not only for gamers, but perhaps also for architects, inventors and engineers working on 3D models. The cherry on the muffin in this respect is the inclusion of head-tracking technology - step to the side to shift your angle of view and your view of the 3D objects on screen will be altered accordingly.

The video certainly poses questions as to the future of human-computer interaction - not necessarily all intentional. Non-touch typists may balk at the idea of a keyboard positioned behind a busy screen (the display may be transparent - that's not to say the information it displays is). Similarly, objects arranged behind one another will necessarily impede view.

But to quibble at the details is rather to miss the point. "This project advances research in current display technologies hoping to provide a more interaction with everyday desktop computing of the future," said Cati Boulanger, a researcher at the Applied Sciences Group. Even with a working prototype, this is a technological what if, not a thou shalt.

See below for a demo video of the prototype in use.

 

14 year-old designs functioning Lego printer

 

The printer employs three motors to control the motion of a felt tip pen. Overweel converts source image files into to a text file of 1s and 0s using Paint.NET, which is then (after some tinkering) imported into RobotC - a development environment used to control Lego Mindstorms NXT robots (among other things) based on the C programming language.

Two of the PriNXT's motors control the pen along the X and Y axes, while the third lifts and lowers it from the page. The printer also makes use of two touch sensors, a light sensor and a color sensor. The light sensor is cleverly used to assist with the vertical motion of the pen.

This is by no means Overweel's first foray into Lego engineering. Only last month, he blogged about his Skype-controlled NXT Car. Check out Overweel's video of the printer fulfilling its raison d'être below.

Office 15 leaks indicate Metro-influenced UI and touch mode

 

While Microsoft isn't set to release Office 15 as a public beta for a few months yet, the company provided a sneak peak to a select group of businesses, partners and OEMs on January 31st in the form of a technical preview. Despite the testers being required to sign non-disclosure agreements, some screenshots and details have started to leak out from those who received access to the beta.

The most immediately obvious change is the influence of Microsoft's Metro UI, which was originally created for Windows Phone 7 and will be seen in Windows 8. In Office 15, Microsoft looks to have merged the Metro UI with its much-maligned Ribbon interface that debuted in Office 2007. The ribbon's default setting appears to be collapsed which, along with a fullscreen "backstage" menu, results in a much cleaner look - although users will be more concerned with how easy it is to use.

Like Windows 8, Office 15 also looks set to embrace touch to enable easier use on tablets and touch-enabled PCs. Windows President Steven Sinofsky has said in a blog post that desktop versions of Word, Excel, PowerPoint and OneNote optimized for touch and minimal power usage will be included with Windows 8 on ARM (WOA). A (currently non functional) Touch Mode button suggests that users will be able to switch between touch and mouse/keyboard inputs depending on the device on which they are using the application.

Microsoft is yet to respond to the leaks - and probably won't - so we'll just have to wait and see if they - and others, such as possible Skype integration - prove correct or not. The company has said is that the Office 15 public beta will be available this northern summer, with expectations that Office 15 - or whatever the new version of Office will be called - will be released before the end of the year. Additional leaked images can be seen at The Verge.

Hyundai to unveil i-oniq concept car in Geneva

 

Hyundai's newest concept car, the 4.4 meter-long (14.4 ft) four-seater i-oniq electric sports hatchback, features a 109 PS electric motor and a range-extending 3-cylinder 1.0 liter petrol engine. In electric-only mode, the i-oniq has a range of 120 km (75 miles), but with the petrol engine producing electricity, the range extends beyond 700 km (435 miles). In range-extender mode, the i-oniq is an emissions champion, producing a paltry 45 g/km of CO2.

The Hyundai i-oniq concept car will be unveiled during Hyundai's press conference at the 2012 Geneva Motor Show on March 6.

 

 

 Universities and scientific organizations all over the world are currently looking into ways of growing functioning heart cells on the heart, to replace the tissue that dies when a heart attack occurs. As things currently stand, the body replaces that tissue with non-beating scar tissue, leaving the heart permanently weakened. Most of the experimental techniques for generating new tissue involve introducing some sort of micro-scaffolding to the affected area, providing a framework for new cells to grow on. That scaffolding has consisted of materials such as carbon nanofibers and gold nanowires, which would have to be surgically applied to the heart, sort of like a Band-Aid. Now, however, researchers from the University of California, San Diego are reporting success in animal trials, using an injectable hydrogel.

The team is being led by Karen Christman, a professor in UCSD's Department of Bioengineering.

They started by obtaining cardiac connective tissue, then used a cleansing process to remove its muscle cells, freeze-dried it, milled it into a powder, and used an enzyme to liquefy it. When injected into the hearts of pigs with cardiac damage, the liquid turned into a porous, semi-solid gel upon reaching body temperature. That gel subsequently provided a scaffold for new tissue growth, and the pigs' condition improved.

Besides acting as a scaffold, it is suspected that the gel might also provide biochemical signals, which prevent the surrounding heart tissue from deteriorating further.

Christman believes that the liquid could be injected using a catheter, so surgery and general anesthesia would not be required. While other scientists have developed heart-repairing hydrogels before, she notes that those substances would not work with catheters, as they would gel too quickly.

When injected into rats, the gel wasn't rejected and didn't cause arrhythmic heart beating - an indication that it could also be biocompatible with humans. A spin-off company, Ventrix, is planning clinical trials sometime next year.

Details on the hydrogel's production process can be seen in the video below.
