Call phones from Gmail

Gmail voice and video chat makes it easy to stay in touch with friends and family using your computer’s microphone and speakers. But until now, this required both people to be at their computers, signed into Gmail at the same time.

Calls to the U.S. and Canada will be free for at least the rest of the year and calls to other countries will be billed at our very low rates. We worked hard to make these rates really cheap (see comparison table) with calls to the U.K., France, Germany, China, Japan and many more countries for as little as $0.02 per minute.
This feature to U.S. based Gmail users over the next few days, so you’ll be ready to get started once “Call Phones” shows up in your chat list (you will need to install the voice and video plug-in if you haven’t already).

CMMI( Capability Maturity Model Integration)Levels of software Industry

This is an industry-standerd model for defining and measuring the maturity of a software company's development process and for providing direction on what they can do to improve their software quality.it was developed by the software development community along with the software engineering institute(SEI).
It has 5 Levels

Level One(CMMI1)
Company has no standard process for software development. Nor does it have a project-tracking system that enables developers to predict costs or finish dates with any accuracy.

Level Two(CMMI2)
Company has installed basic software management processes and controls. But there is no consistency or coordination among different groups.

Level Three(CMMI3)
Company has pulled together a standard set of processes and controls for the entire organization so that developers can move between projects more easily and customers can begin to get consistency from different groups.

Level Four(CMMI4)
In addition to implementing standard processes company has installed systems to measure the quality of those processes across all projects.

Level Five(CMMI5)
Company has accomplished all of the above and can now begin to see patterns in performance over time so it can tweak its processes in order to improve productivity and reduce defects in software development across the entire organization.
Level 1 Initial
Level 2 Repeatable
Level 3 Defined
Level 4 Managed
Level 5 Optimizing

4G wireless technology

4G is short for Fourth Generation wireless Technology. It is basically the extension in the 3G technology with more bandwidth and services offers in the 3G. The expectation for the 4G technology is basically the high quality audio/video streaming over end to end Internet Protocol. If the Internet Protocol (IP) multimedia sub-system movement achieves what it going to do, nothing of this possibly will matter. WiMAX or mobile structural design will become progressively more translucent, and therefore the acceptance of several architectures by a particular network operator ever more common.


After successful implementation, 4G wireless technology is likely to enable ubiquitous computing, that will simultaneously connects to numerous high date speed networks offers faultless handoffs all over the geographical regions. Many network operators possibly utilize technologies for example; wireless mesh networks and cognitive radio network to guaranteed secure connection & competently allocates equally network traffic and bandwidth.

Some of the companies trying 4G communication at 100 Mbps for mobile users and up to 1 Gbps over fixed stations. They planned on publicly launching their first commercial wireless network around 2010. As far as other competitor’s mobile communication companies working on 4G technology even more quickly. Sprint Nextel was planned to launch WiMAX over 4G broadband mobile network in United States. Some of the other developed countries like United Kingdom stated a plan to sale via auction of 4G wireless frequencies couple of years back. The word “MAGIC” also refers to 4G wireless technology which stands for Mobile multimedia, Any-where, Global mobility solutions over, Integrated wireless and Customized services.

Hutton on Caste census in 1931

A group of federal ministers headed by Finance Minister Pranab Mukherjee is preparing to meet this week, according to a PTI report, to deliberate on whether every Indian citizen should be questioned on their caste in the Census 2011, like census officials did in 1931. They might also want to listen to what J.H. Hutton, the commissioner of the 1931 census - who envisioned “India in the fullness of time to be of one caste, a united nation,” in his own words - had to say about including caste in the census.

J.H. Hutton (1885-1968) was an anthropologist-cum-administrator, who “brought to bear on his work as the census commissioner… professionalism of a high order,” according to anthropologist K.S. Singh in the foreword to the 1989 reprint of the 1931 report. Mr. Hutton went on to author a book in 1946 called ‘Caste in India: its nature, functions and origins.’

Mr. Hutton had two million enumerators working for the census of 1931 which counted the total population of British India at that time as 353 million. In the all-India census report that Mr. Hutton presented to British administrator Harry Haig in Simla in the summer of 1933, he makes some interesting observations about whether tabulating population on the basis of caste was a good idea.

CAPTCHA-completely automated public Turing test to tell computers and humans apart

CAPTCHA stands for "completely automated public Turing test to tell computers and humans apart." What it means is, a program that can tell humans from machines using some type of generated test. A test most people can easily pass but a computer program cannot.

You've probably encountered such tests when signing up for an online email or forum account. The form might include an image of distorted text, like that seen above, which you are required to type into a text field.

The idea is to prevent spammers from using web bots to automatically post form data in order to create email accounts (for sending spam) or to submit feedback comments or guestbook entries containing spam messages. The text in the image is usually distorted to prevent the use of OCR (optical character reader) software to defeat the process. Hotmail, PayPal, Yahoo and a number of blog sites have employed this technique.
