Facebook will disappear in few years


The popular social network will essentially become a non-entity in several years, claims Ironfire Capital founder Eric Jackson.


Will Facebook suffer the same fate as MySpace in a few years? That's what one analyst predicts.

Speaking on CNBC's "Squawk on the Street" program Monday, Eric Jackson, founder of Ironfire Capital, said that Facebook will lose its dominance as a social network in five to eight years.


In his forecast, Jackson cited Facebook's inability to crack the mobile market and the stock's 27 percent nosedive since the company's IPO.


"In five to eight years they are going to disappear in the way that Yahoo has disappeared," Jackson said. "Yahoo is still making money, it's still profitable, still has 13,000 employees working for it. But it's 10 percent of the value that it was at the height of 2000. For all intents and purposes, it's disappeared.

World First Website

world first website




The main idea of World Wide Web (WWW) was proposed 2 decades ago in March 1989 by Tim Berners-Lee. It was written to persuade CERN that a global hypertext system was in CERN’s best interest. The term World Wide Web was never thought and mentioned in his proposal, rather it was called Mesh. The term WWW was coined only when he was writing the code in 1990.

Finally he finished is coding for WWW in 1990 based on his proposal, along with the standards for HTML, HTTP, and URLs.It was 1991 when the first website ever was created with URL http://info.cern.ch. The first content in the first website was to explain the World Wide Web. 
first webpage



The first web page file name was TheProject.html. And it was actually located at following link:http://info.cern.ch/hypertext/WWW/TheProject.html
However the first web page is not there. But don’t worry you can still browse the world’s first web page here.
If you are interested in reading Tim’s proposal, you can still read it here.

Why keyboard letters are not in alphabetical order?



When someone invented the typewriter, why didn’t he put the A-Z keys in sequence? I believe it is certainly an obvious question for any computer/type writer noob. In fact when I started getting my hands on computer keyboard, even I had this question. Lets find it out -

Logic behind the reason


Initially in 1860s, the characters on the typewriters were arranged in alphabetical order. At that time a typewriter use to work using a set on the end of a metal bar which strikes the paper when its key was pressed. However, this procedure was not at all compatible to type faster. Still an operator had learned to type at speed by facing lot complications. Letters that placed close together on the keyboard became tangled with one another, forcing the typist to manually unstick the type bars. This also caused staining the document frequently and jams in typewriter machine. A business associate suggested using nice trick by splitting most commonly keys to speed up typing, so that they also don’t get tangled very often. Rearrangement of keys introduced the word QWERTY, the most commonly used modern-day keyboard layout.



QWERTY keyboard layout

QWERTY is designed for English language. By all means the purpose was to rearrange the keys that were expected to be used in quick sequence were less expected to hold up with each other. The top row was planned to have all the letters for the word ‘typewriter’ hence a typist can easily type the most common words like ‘typewriter’ more quickly.
QWERTY was designed after spending a lot of time on research allowing one hand to move into position while the other hand strikes a key. Thousands of English words can be spelled using only the left hand and right hand separately. And therefore an unfortunate consequence of the layout goes to right-handed typists because more English words can be spelled using only the left hand. QWERTY layout is helpful for those who use their right hand primarily for the mouse leaving the left hand type.
Arrangement of keys under QWERTY layout may not sound completely sensible to many of us today as we are now many decades ahead to that time.

Now, there seems to be good news for all the SMS fans or Heavy SMS Users! Indian Telecom regulator Telecom Regulatory Authority of India (TRAI) today increased the limit of One hundred SMS (100 SMS) per day per SIM to Two hundred SMS (200 SMS) per day per SIM. TRAI said that it has received representations from some of the service providers and consumers to increase the limit of 100 SMS per day per SIM. The Authority has considered these representations and decided to increase the limit of one hundred SMS per day per SIM to two hundred SMS per day per SIM/ Subscriber.

What is 1g, 2g, 2.5g, 3g, 3.5g, 3.75g, 3.9g, 4g?

In 1982
 
1G
First Generation was introduced where network signals were analogue and used Frequency Division Multiple Access (FDMA).

2G
Second Generation was launched in 1992 in which signals and speech channels were digitally encrypted. 2G used Time Division Multiple Access (TDMA).

2.5G
Deployed in 2003  which implemented High Speed Circuit Switched Domain(HSCSD) data rate 236.8kbps to 384kbps by using Enhanced Data Rate for GSM Evolution (EDGE).

3G
It has very different functions like it allows simultaneous use of speech and data services at higher rates and better spectral efficiency.


3.5G
HSUPA upgrades the uplink for higher data transfer speed and capacity of 1.4 ,1.9 ,5.8 Mbps. HSUPA name is given by Nokia and used in its phones only but 3GPP does not  support this name. HSDPA High-Speed Downlink Packet Access having faster speed from 1.8 ,3.6 ,7.2 to 14 Mbps.

3.75G
HSPA High Speed Packet Access is a combination of HSUPA  and HSDPA that improves the performance of W-
CDMA and can attain speed 21Mbps to 28Mbps. HSDPA High-Speed Downlink Packet Access having faster speed from 1.8 ,3.6 ,7.2 to 14 Mbps.

3.9G
HSOPA Some networks dubbed it as 4G. This project is known as Long Term Evolution and uses OF- DMA Orthogonal Frequency-Division Multiplexing which will offer data rate at 170Mbps for up-link and 320Mbps for down-link.

4G 
It Constitute of 4G has not been standardized yet.It is non-backward compatible with new higher frequencies
bands. It is defined to be comprehensive and secure for the users. 4G will only be packet- based (all-IP) switched
network. Facilities like IP-telephony (IP-basedvoice data), Ultra broadband Internet Access
1GBps (Gigabit
speed) Support for IPV6 protocol, Gaming Services, High Definition HDTV, Streamed Multimedia and many more new services are added!!! UMTS operates on frequencies of 850/900/1700/1900/2100 MHz. Most 3G phones
support at least 2 frequencies. No 3G phone available which supports all 3G frequencies.
It depends on service provider what speed and frequency it adopts for its 3G network and what type of 3G
compatible phone you have to fully exploit ,utilize and enjoy the services.

How to Create a Strong Password ?


You must follow the following criteria while creating a Strong Password:
  •     The password must be a minimum of 8+ characters.
  •     The password must have 1 number , 1 special character, 1 Upper Case character.

A very simple example that I use to explain my friends and colleages is : P@ssw0rd. It fullfills all the criteria's. The 'a' is replaced by a special character @. The 'P' is of upper case. The 'o' is replaced by the numeral 0.
Well, you can now convert your regular password into a Strong Password by following a few changes like the example I have mentioned above for the simple password - P@ssw0rd.

  •     Make the first character Upper Case.
  •     Change all 'a' in the password to the special character @.
  •     Change all 's' in the password to the special character $.*
  •     Change all 'l' in the password to the special character !.
  •     Change all 'o' in the password to the numerical 0.
  •     Change all 'i' in the password to the numerical 1.
