Despite the security concerns that have plagued Facebook for years, most people are sticking around and new members keep on joining. This has led Facebook to break records numbers with over one billion monthly active users as of October 2012—and around 600 million active daily users.

We share our lives on Facebook. We share our birthdays and our anniversaries. We share our vacation plans and locations. We share the births of our sons and the deaths of our fathers. We share our most cherished moments and our most painful thoughts. We divulge every aspect of our lives. We even clamor to see the latest versions even before they're ready for primetime.

But we sometimes forget who's watching.

The world wide web which has become the hub of storing and restoring information, considered to be the safest vault, is a mere toy in the hands of a few computer geniuses. Hackers, Black Hat Hackers, villains, crackers, cyber-criminals, cyber pirates as they are well-known, throw a malicious software or virus at a system to gain the access to the desired information. Piqued by curiosity, they may perhaps break into your system too. Here are top 10 hackers or the whiz kids who put the world in awe with their dexterity.

The Newton-Raphson Metho d

The Newton-Raphson Metho d
1 Intro duction
The Newton-Raphson method, or Newton Method, is a powerful technique
for solving equations numerically. Like so much of the differential calculus,
it is based on the simple idea of linear approximation. The Newton Method,
properly used, usually homes in on a root with devastating efficiency.
The essential part of these notes is Section 2.1, where the basic formula
is derived, Section 2.2, where the procedure is interpreted geometrically,
and—of course—Section 6, where the problems are. Peripheral but perhaps
interesting is Section 3, where the birth of the Newton Method is described.

how to square my computer from hackers

INTRODUCTION

I’ve been interested in looking at the information contained in credit cards ever since I first heard about the Square card reader. The idea of such a tiny device being able to parse all the information on a credit card directly into your phone is fascinating to me and I wanted to figure out how it worked and if I could play with it a little bit. Unfortunately, Square moved from a very simple circuit design to a larger, encrypted version before I got mine. Coming into this weekend, I didn’t even have the expertise to figure out the simple version, much less the encrypted version and so I had mostly given up on working with credit card information.

However, one of my friends happened to have a few of the old Square readers that he gave me to work with. That gave me the opportunity to see what I could do and start hacking on this project.

how to delete my facebook account

Facebook may boast 1.28 billion monthly active users, but the social network isn’t for everyone. Maybe you don’t find it all that useful, or you’ve received one too many FarmVille requests. Or perhaps the June 2014 disclosure that the company messed with users’ News Feeds as part of a research experiment proved to be the final straw (even if monkeying with News Feeds is what Facebook does all the time). Whatever the reason, you’ve had it with Facebook.

So how do you make a clean break? You’ve got two choices—deactivating your Facebook account or deleting it outright.

5 Of The World’s Most Famous Hackers

 Most Famous  Joel Lee

 

There are two types of hackers. First, you’ve got the kind that is so often portrayed by Hollywood as an anti-social nerd with a chip on his shoulder out to dominate the cyberworld by breaking into secure networks and messing things up. Second, you’ve got the kind of people who just enjoy fiddling around with software source code and hardware gigs. That’s right. The term “hacker” originally referred to the second type, which held absolutely no malevolent connotations. Only recently has the term been used to refer primarily to criminal masterminds. There are good hackers and bad hackers! Nowadays, benevolent hackers are often called “white hats” while the more sinister are called “black hats.”
In this article, I’ll be talking specifically about famous hackers that don hats of black. Here are five of the most widely known black hatters and what happened to them for their recklessness.
