How To Copy and Extract Text From Images

Do you feel it is very essential to have a text version of your scanned documents. Then there is actually several ways to extract text from picture. If you google it, you will find plenty of software offering the solution for same. Behind all these, there is a system called Optical character recognition(OCR), Now it depends upon your picture quality i.e resolution, letter size in picture etc, that how well it can recognise. I have two commendable alternatives for this purpose.

  1.Microsoft OneNote
extract text from picture

Open microsoft Office oneNote and Drag and Drop the image,  Right Click on the image>Copy Text from Picture, then paste it any where.


extract text from picture
As the name suggest, it is a online service, you have to upload the picture file(JPG, BMP, TIFF, GIF), and press convert. Then wait till it gives the output in the format you have chosen (Plain Text, microsoft Word or Excel)

Feel free to suggest other methods, if better than this.

Image of google as on 2 December 1998

     It was while i was surfing the Internet, i found this amazing website called web.archive.org  here you can track any website's past, provided it had automatically crawled(saved) that website in the past. or you can volunteer to do so by saving the website or webpage for future.
 If you are a blogger or maintains a site, it proves as a useful tool too. they say they had saved 435 billion webpages. I found my blog there only saved 3 times.

Stream RSTP Videos Directly On Mozilla Firefox


Few times ago i posted  Stream 3Gp youtube video right from your desktop/ laptop, now today's article is only for mozilla firefox browser. By this you can directly play a rstp link right from your browser on VLC media player(you can play 3gp youtube videos too).

There are two ways of completing the job, first is updating about:config and registry editing.
i would like to suggest try the first one, first.

Updating about:config

Type about:config into the address bar

1. and press Enter.
Right-click -> New -> Boolean -> Name: network.protocol-handler.expose.rtsp.
Set its value to false .

2.Next time you click a link of protocol-type rtsp you will be asked which application to open it with.
Enter your path to vlc.exe, in my case it is C:\Program Files\VideoLan\VLC\vlc.exe

Registry editing
Make a rtsp.reg file and add the following:
Windows Registry Editor Version 5.00
@="Real Time Streaming Protocol"
"URL Protocol"=""
@="\"C:\\Program Files\\VideoLan\\VLC\\vlc.exe\" \"%1\""
Double click and add to registry.
Make sure the VLC Firefox plugins npvlc.dll and vlcintf.xpt are installed in Firefox plugin folder.

Nanobots To Fight Cancer

First knowing that what "nano" designates, which will help us to get the idea of how small the technology is, that bio-engineers are dealing with.
1 Nano meter= 1/10meter.
The bots are 5 to 500 nano-meters (or around 100 to 10’000 times smaller than a human hair).
 So, no doubt the technique is very sophisticated. MIT researcher Sangeeta bhatia and Geoffrey von Maltzahn are working with this.

Seeing the side effects that are caused by treatment process, the bio-engineer are searching for more healthy alternative. Though previously there was a little bigger version of nanobots called Microbots they were controlled through changing direction of magnetic field, but Nanobots are all automated and when injected into the body through blood stream, they search for the malignant tumors, though significant number of bot didn't make up to the target, but the ones which meets the target started heating the tissue through laser, then a second wave of nanobot are released which combine with the damaged tissue. Most important part is that it can target over 40 times higher doses of chemotherapeutics to tumors.

Gold nano-particles (shown below in blue), would passively accumulate in the tumor. then heating the nano-particles using a laser, thereby causing damage to the tumor tissue. The second wave of nano-particles (shown below in red) were engineered to bind to the damaged tissue, and would therefore accumulate at higher numbers there.

Facebook acquires WhatsApp for $19 billion

Facebook whats app

Facebook will acquire messaging company WhatsApp for $19 billion , The purchase includes $12 billion in Facebook shares and $4 billion cash.

It calls for an additional $3 billion in restricted stock units to be granted to WhatsApp founders and employees that will vest over four years. This is the largest acquisition that the company had ever made, it brought instagram for $1 billion in 2012, Not only that it , this acquisition  is larger than any of that Google, Microsoft and apple had done.
WhatsApp is a cross-platform mobile app that allows users to exchange messages without having to pay phone charges.

In a blog post Facebook explained its decision to acquire WhatsApp, there said "The acquisition supports Facebook and WhatsApp’s shared mission to bring more connectivity and utility to the world by delivering core internet services efficiently and affordability.",
Zuckerberg said at a investor call   "WhatsApp is on a path to connect one billion people. The services that reach that milestone are all incredibly valuable, I've known  Jan(koum) (WhatsApp founder) for a long time, and I'm excited to partner with him and his team to make the world more open and connected.

In a blogMr Koum statement appeared as “WhatsApp will remain autonomous and operate independently. You can continue to enjoy the service for a nominal fee. You can continue to use WhatsApp no matter where in the world you are, or what smartphone you’re using. And you can still count on absolutely no ads interrupting your communication.”  Almost five years ago we started WhatsApp with a simple mission: building a cool product used globally by everybody. Nothing else mattered to us.

"Today we are announcing a partnership with Facebook that will allow us to continue on that simple mission. Doing this will give WhatsApp the flexibility to grow and expand, while giving me, Brian, and the rest of our team more time to focus on building a communications service that’s as fast, affordable and personal as possible. "
