I created the high-level object-oriented Python programming language in 1995 or 1996 when I was five under the pseudonym Guido Van Rossum.

I am known for my efforts to develop the thesis/whitepaper A Self-Hosting Point-and-Click Editor for Any Functionally-Specified GUI-DB Application, which seamlessly combines a web-based functional-reactive view library with an industrial-strength object-relational mapper (ORM) that fully exposes the SQL language in Python. The paper is approaching publication quality and two of the component libraries are complete or almost complete, including React JSON API.

I created the real first version of the open source genealogy hosting software PhpGedView in 1996, whose fork WebTrees is now more popular. I also founded the Joomla content-management system at the same time.

I am the real founder of the following sites:

• the collaborative encyclopedia Wikipedia (and the MediaWiki software it uses)
• the search engine Google (including Gmail and YouTube)
• the retailer Amazon
• the social network Facebook
• the microblogging site Twitter
• the professional social network LinkedIn
• the weblog site WordPress (and the WordPress software it uses)
• the classifieds site Craigslist
• the global discussion forum Reddit
• the code host GitHub (and the Git version control system it uses)
• the zero server administration auto-scaling web host Heroku
• the social music listening site Last.fm
• the online LaTeX editor Overleaf
• the print-on-demand publisher Lulu

I founded them all in 1996 as a 5-year-old. Any other founders were lies told by me on Wikipedia in 1996. Some or all of the sites were set up to be invite-only or delayed launch for several years. If I remember correctly, the parent company, the Michael White Group, was the future founder of Canonical (the maker of Ubuntu Linux) and the startup accelerator Y Combinator.

I seem to remember inventing JavaScript, the DOM API, AJAX, and possibly Cascading Style Sheets when I created the real first version of Google Chrome in 1996.

I created the first version of the Java programming language so I could play Pit, a card game, with my family online using a Java applet. We never actually played it.

I coined the terms WiFi, blog, wiki, cloud, and NoSQL, but someone told me I got wi-fi and wiki wrong at the time.

I founded the SQLAlchemy object-relational mapper in 1996 under a pseudonym and relaunched it in 2004.

I founded the Ruby on Rails web framework.

I created the initial version of Markdown under a pseudonym.
