Sir Tim Berners-Lee

About Sir Tim Berners-Lee
>Founder of WWW & HTML_W3C
Sir Tim Berners-Lee invented the World Wide Web in 1989 while working as a software engineer at CERN. With many scientists participating in experiments at CERN and returning to their laboratories around the world, these scientists were eager to exchange data and results but had difficulties doing so. Sir Tim understood this need, and understood the unrealized potential of millions of computers connected together through the Internet. Sir Tim documented what was to become the World Wide Web with the submission of a proposal specifying a set of technologies that would make the Internet truly accessible and useful to people. Despite initial setbacks and with perseverance, by October of 1990, he had specified the three fundamental technologies that remain the foundation of today’s Web (and which you may have seen appear on parts of your Web browser): HTML, URL, and HTTP. He also wrote the first Web page editor/browser and the first Web server. By the end of 1990, the first Web page was served. By 1991, people outside of CERN joined the new Web community, and in April 1993, CERN announced that the World Wide Web technology would be available for anyone to use on a royalty-free basis. A graduate of Oxford University, Sir Tim teaches at Massachusetts Institute of Technology as a 3Com Founders Professor of Engineering and in a joint appointment in the Department of Electrical Engineering and Computer Science at CSAIL. He is a professor in the Electronics and Computer Science Department at the University of Southampton, UK, Director of the World Wide Web Consortium (W3C), and author of 'Weaving the Web' and many other publications.

Jeff Atwood

About Jeff Atwood
>Author_Coding Horror
I'm Jeff Atwood. I live in Berkeley, CA with my wife, two cats, three children, and a whole lot of computers. I was weaned as a software developer on various implementations of Microsoft BASIC in the 80's, starting with my first microcomputer, the Texas Instruments TI-99/4a. I continued on the PC with Visual Basic 3.0 and Windows 3.1 in the early 90's, although I also spent significant time writing Pascal code in the first versions of Delphi. I am now quite comfortable in VB.NET or C#, despite the evils of case sensitivity. I'm currently learning Ruby. I consider myself a reasonably experienced web software developer with a particular interest in the human side of software development, as represented in my recommended developer reading list. Computers are fascinating machines, but they're mostly a reflection of the people using them. In the art of software development, studying code isn't enough; you have to study the people behind the software, too.

About Alexandra Waldherr
>Chemical Engineering Student_TU Vienna
I am 18 years old and currently attend the final year at a higher technical college for chemical engineering. Since age 12, I am passionate about science, especially physics, programming and chemistry. In 2018 I finished the Viennese Physics' Olympiad best girl, this summer I worked with the department for material chemistry of TU Vienna and as a developer at AF-Institute Vienna (AI and data management for the medical sector). My passions generally evolve around the tiny things that matter - a beauty hidden almost invisible in everyday life whether it is now microbiology, genetic code or quantum computers. In autumn 2019 I helped with research at CERN Geneva and was invited to speak at the FifteenSeconds-Festival and introduced quantum computing at WeAreDevs Vienna. In chemistry, quantum mechanics have a long tradition - but how can we harness intriguing calculations and maybe change whole industries? Practical concepts of quantum computing still need lots of research and curiosity... I would therefore go with Schroedinger and say there is a 50% chance of me being a quantum computing expert. Your observation shall determine!

About Kerstin Ewelt

I work at Quora in the "Writer Relations" team and Quora in German was the fourth language we launched. The baby is growing and thriving. Without the commitment of the Quora community, this would not be possible - I am happy about this every day and I am grateful to be able to offer Germany, Austria and Switzerland a knowledge platform that stands for high-quality content and credibility. Meanwhile, I am responsible for the northern European area: Dutch, Danish, Norwegian, Swedish, Finnish – check out the language versions of Quora if you are interested. I studied "Political Science" at the FU Berlin and afterward I worked for different media companies (Bild, Berliner Zeitung, F.A.Z.) In 2003 I went to the USA – first to Pennsylvania and then to California. Now I made myself comfortable in Silicon Valley and experienced some tech company first hand. Before I joined Quora, I was responsible for the German-speaking market at Yahoo Search. As a Senator, I am involved in the think tank "Senate of the Economy" (Commission: Digital Future) and enjoy the exchange with the "Fellow Senators". Although I have been away from Germany for a long time, I still miss a lot (not only bread), but I have also learned that home means more than just a postal address. And I have decided to make the best of my two worlds every day. This works – most of the time ;-)

I founded the Google Dev Group Hannover and the Female Techmakers Meetup Hannover. Bringing people together, learning together and supporting diversity are essential topics for me.

About Maria Laaksonen
>Customer Success Engineer_Aito
Maria works as a Customer Success Engineer at Aito. After kicking off her career in Academia and researching brain cancer, she gradually shifted more towards the private side of the BioIT industry. And now, she works with machine learning and applying it to solve business problems. Thanks to her diverse background, Maria is highly skilled with hardcore data analysis but also extremely fluent with people. In front of them, on stage, Maria likes to dive deep into ML solutions and why, how, when and where to use them. She can shed simple light on complex issues and help her technical (or non-technical) audience avoiding the usual AI/ML pitfalls. But be aware: sometimes she might throw in some nice-to-know facts about Yorkshire terriers. Or humbly brag with her (honestly: very impressive) painting skills. But mostly she talks tech – at least when on duty.
