Happy 40th Birthday UNIX!

UNIX turns 40 - in 1969 group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna developed UNIX. Today Unix offered in many flavors and developed over time by AT&T as well as various commercial vendors (such as IBM, HP, Sun, Apple etc) and non-profit organizations. CW article concluded that after four decades, the future of the operating system is clouded, but its legacy will endure in form of Linux and Microsoft NT operating system:

In August 1969, Ken Thompson, a programmer at AT&T subsidiary Bell Laboratories, saw the month-long departure of his wife and young son as an opportunity to put his ideas for a new operating system into practice. He wrote the first version of Unix in assembly language for a wimpy Digital Equipment Corp. (DEC) PDP-7 minicomputer, spending one week each on the operating system, a shell, an editor and an assembler.

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.
