1/3 = 0.333333.....
2/3 = 0.666666.....
1/3+2/3 = 0.9999999.... = 3/3 = 1

x = .9999~
10x = 9.9999~
10x - x = 9.9999~ - .9999~
9x = 9
x = 1

The proper proof is

0.99999...

= 9/10 + 9/100 + 9/1000 + ...

= sum( 9/10^i ), over i = 1 to infinity

= sum( 9/10 * 1/10^i ), over i = 0 to infinity

= (9/10) / (1 - 1/10), the sum of a geometric series

= (9/10) / (9/10)

= 1

It's from c, the programming language, means "not equal to". ! is the boolean inversion operator.

Examples:

iron != lulz
tuq !!!= gay

etc
