Happy 40th Birthday Mouse!

The basic workings of a mouse have changed little in 40 years

The basic workings of a mouse have changed little in 40 years

The humble computer mouse celebrates its 40th anniversary today. Currently I'm using two buttons and a scroll wheel mouse. At work I've a Microsoft IntelliMouse; it has four buttons and a scroll wheel.

I think mouse helped creating modern personal computers including powerful GUI interface, email, browser etc.

From the BBC page:

On 9 December 1968 hi-tech visionary Douglas Engelbart first used one to demonstrate novel ways of working with computers.

The first mouse that Dr Engelbart used in the demo at the Fall Joint Computer Conference (FJCC) was made of wood and had one button.

Much of the technology shown off in the demo inspired the creation of the hardware and software now widely used.

Spam now makes up more than 80% of mail message traffic. The first recognizable e-mail marketing message was sent on 3 May, 1978 to 400 people on behalf of DEC - a now-defunct computer-maker. You can see the first spam message here (archived version) including interview with Thuerk, the sender. From the BBC news page:

Statistics gathered by the FBI suggest that 75% of net scams snare people through junk e-mail. In 2007 these cons netted criminals more than $239m

Statistics suggest that more than 80%-85% of all e-mail is spam or junk and more than 100 billion spam messages are sent every day.

The majority of these messages are being sent via hijacked home computers that have been compromised by a computer virus.

Spam reaches 30-year anniversary
