Mainstream Open Source turns 20

While open source software is ubiquitous, recognized across industries as a fundamental infrastructure component as well as a critical factor for driving innovation, the "open source" label was coined only 20 years ago.

The concept of open source software – as opposed to free software or freeware – is credited to Netscape which, in January 1998, announced plans to release the source code of its proprietary browser, Navigator, under a license that would freely permit modification and redistribution. This code is today the basis for Mozilla Firefox and Thunderbird.
The Open Source Initiative (OSI) regards that event as the point at which "software freedom extended its reach beyond the enthusiast community and began its ascent into the mainstream".

A tecnologia às vezes tem algumas "tiradas" engraçadas; como ver um anúncio da Microsoft Azure sobre uma foto do Google em um anúncio sobre o Google Drive. E o "ad" é colocado pelo próprio Google!

In the early 1970s, most students working on complexity sought to either tame the beast or establish that all such efforts are futile. Manuel Blum took a different approach to the subject: he decided to make friends with complexity, to turn the tables on it, and use it to accomplish useful things. Perhaps the most consequential of Blum’s applications of complexity relates to randomness. In 1986, Blum and his student Shafi Goldwasser (who later received the 2012 ACM Turing Award with Silvio Micali) came up with a public key cryptography scheme based on the Blum-Blum-Shub generator which, unlike RSA, had been mathematically proven to be as hard to break as factoring. In the 1990s, along with Luis von Ahn and others, Blum helped develop the “Completely Automated Public Turing test to tell Computers and Humans Apart,” or CAPTCHA , now a ubiquitous device used to determine whether a webpage visitor is human.
