Solid (web decentralization project)
Two decades after Berners-Lee invented the World Wide Web in 1989, he outlined the design issues of what later became the Solid project in drafts he wrote for the World Wide Web Consortium. Berners-Lee became increasingly dismayed at seeing his invention being abused, such as when Russian hackers allegedly interfered with the 2016 US elections, when the Facebook–Cambridge Analytica data scandal became public, when Facebook in 2012 conducted psychological experiments on nearly 700,000 users in secret, and when Google and Amazon applied for patents on devices that listen for emotional changes in human voices.
Search engine technology
The World Wide Web Wanderer, developed by Matthew Gray in 1993 was the first robot on the Web and was designed to track the Web's growth. Initially, the Wanderer counted only Web servers, but shortly after its introduction, it started to capture URLs as it went along. The database of captured URLs became the Wandex, the first web database.
