Why it is taking me 4 years and counting to quit facebook

Administrator's picture
I like you and you and especially YOU, have considered quitting Facebook. Often. And for a long time. A really, really long time. Yet, here I am. We all realize what an extreme time suck Facebook is. Lured in for a brief check on upcoming event, we realize we are 58 photos deep in the 120 pictures from your ex’s wedding photos. Gads, did you see that dress?

Interesting facts related to computer that you would like

Here are some interesting points related to computer that you would love to hear:
1. It took the radio 38 years and the television only 13, but the internet reached 50 million users in only 4 years.
 2. The computer mouse was invented by Doug Engelbart in 1963. It was made out of wood (weird, huh).
 3. In 2009 the average number of Internet transactions per second was 2,000.
 4. Early hard disks in personal computers held only 20 MB of data and cost around $800. In 2010 you could get a 2 GB flash drive for around $8. This implies that there is a 100-fold reduction in the price and a 100-fold increase in storage capacity.

What is Captcha and how it works

What is Captcha?
CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. In simple words it’s the technique to stop web spam. Now what is web spam? Ok, anything that is not relevant to the website but users (or automated bots) try to post comments, links etc are called web spams. Best example is advertisement of Nike shoe in any technical website like Alien Coders which has no relevance for that kind of comment or post. I will discuss about “Web Spam”  in detail in another article.

Alternative option for "reCpatcha from Google"
Catpcha LogoCAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. (Yes, it really should be “CAPTTTCHA.” Don’t blame us; we’re not the ones who made up the term.) It’s a type of challenge test used on web sites to verify that the transaction taking place—the comment being posted, the account being registered, the vote being cast in a poll—is coming from a human and not a computer program. In addition to the examples mentioned above, CAPTCHA are used to block registration spam and contact form spam, to prevent scrapers from stealing email addresses and search bots from accessing private data, to deter dictionary password search attacks, and to preempt servers from getting bogged down by spam and malicious scripts.

Using Captcha may reduce spam but it would also reduce real comments/posts drastically :(

Gmail Increased File upload limitI think majority of us use Gmail for mailing purpose at present followed by Hotmail , Yahoo and so on. In my previous post I had mentioned the Features of different mail providers and Minimal Reasons to choose Gmail for personal mailing system.

There are lots of reasons to choose mail providers, and the attachment size is definitely one of the top reasons to be considered. Recently, Google started to allow file attachment till 10 GB! Of course, there is something that you had to know before using large files as attachment.  I will try to provide an overview on how this large file size email attachment works in Gmail.
