Google Docs adds OCR, converts images and PDFs to text

Google Docs continues to make the case for dumping your desktop work apps, this time with a useful new text recognition feature that converts PDFs or images into plain, editable text. This new OCR feature -- that's optical character recognition -- is quite accurate, and worked pretty well on some old college textbooks scans I had laying around on my hard drive. Things are a bit tricky when you've got a page with multiple columns -- your words might not end up in the right order, but they'll all be there, accurately recorded.

To use OCR, look for the " Convert text from PDF or image files to Google Docs documents" checkbox when you're uploading a file. The file will show up in Google Docs as a text document instead of its original format, so if you want to share the image, you'll have to upload it again with the box unchecked.

Google Operating System tested the new feature and didn't find it quite as accurate as I did. I agree with them that the loss of formatting is a problem, but the OCR was better than the 90% accuracy they noted in their test. Your mileage, obviously, may vary. The typeface, font size and scan quality of your PDF will all affect the results, but it should definitely be easier than re-typing the whole thing by hand.

How To Hide Text In Microsoft Word 2007, Reveal It & Protect It

Sometimes what we hide is more important than what we reveal. Especially, documents with sensitive information, some things are supposed to be ‘for some eyes only’. Such scenarios are quite common, even for the more un-secretive among us. You want to show someone a letter composed in MS Word, but want to keep some of the content private; or it’s an official letter with some part of it having critical data. As important as these two are, the most common use could involve a normal printing job. Many a time we have to print different versions of a document, one copy for one set of eyes and others for other sets. Rather than creating multiple copies and therefore multiple printing jobs, what if we could just do it from the same document? That too, without the hassle of repeated cut and paste. We can, with a simple feature in MS Word – it’s just called Hidden and let me show you how to use it to hide text in Microsoft Word 2007. It’s a simple single click process. Open the document

Clip & Convert Your Video Faster With Quicktime X & The New Handbrake 64-bit [Mac]

Recently a friend of mine asked for my help to find a video of a good presentation to be shown to one of his classes. He also requested for it to be iPod friendly as he would also distribute the video to his students. Three things came to my mind: Steve Jobs, Quicktime and Handbrake . Mr. Jobs is well known for his great presentations which are often used as references. I have several Apple Keynotes videos. For my friend, I decided to choose the one that introduced MacBook Air – the one that never fails to deliver the wow effect to the non-techie audience. It’s a part of January 2008 Macworld Keynote. First step: The Cutting To get only a specific part of the Keynote, I clipped the 1+ hour video into about 20 minutes using Quicktime X (which comes with Snow Leopard). I opened the movie using Quicktime X and chose Trim from the Edit menu ( Command + T ). Then I chose the start and end of my clip by moving both edges of the trimming bar to the desired position. To increase th

Ex-Skypers Launch Virtual Whiteboard Deekit

Although seriously long in the tooth and being disrupted by a plethora of startups, for many years Skype has existed as an almost ubiquitous app in any remote team’s toolkit. So it seems apt that a new startup founded by a team of ex-Skype employees is set to tackle another aspect of online collaboration. Deekit, which exits private beta today, is a virtual and collaborative whiteboard to help remote teams work smarter. The Tallinn, Estonia-based startup is headed up by founder and CEO, Kaili Kleemeier, who was previously a Head of Operations at Skype. She and three colleagues quit the Internet calling giant in 2012 and spent a year researching ideas in the remote team space. They ended up focusing on creating a new virtual whiteboard, born out of Kleemeier’s experience collaborating with technical teams remotely, specifically helping Skype deal with incident management. “Working with remote teams has been a challenge in many ways – cultural differences, language differences, a
