Editing Ian Clarke (computer scientist) (section)

==Professional career==
In September 2002, after leaving Uprizer, Clarke formed Cematics LLC to explore a variety of new ideas and opportunities. Cematics LLC developed a number of products including Locutus - a P2P search application for the enterprise, WhittleBit - a search engine that learns from user feedback,<ref>{{cite web|title=Search Engine Learns From User Feedback|url=http://science.slashdot.org/story/03/08/11/1722244/Search-Engine-Learns-From-User-Feedback?art_pos=1|publisher=Slashdot}}</ref> and 3D17, a web-based [[collaborative editing]] tool.<ref>{{cite web|title=Large Scale Collaborative Editing|url=http://slashdot.org/story/03/10/30/1819241/large-scale-collaborative-editing|publisher=Slashdot}}</ref>

In October 2003, Clarke decided to leave the United States to return to Edinburgh, Scotland. In December 2004, he began work on [[Revver#Dijjer|Dijjer]], a distributed P2P web cache, and [[Indy (software)|Indy]], a collaborative music discovery system, both in conjunction with ChangeTv, a company founded by his long-time collaborator, [[Steven Starr]], who later brought in Clarke and Oliver Luckett as co-founders. In 2003, he was named to the [[Massachusetts Institute of Technology|MIT]] [[Technology Review]] [[TR35|TR100]] as one of the top 100 innovators in the world under the age of 35.<ref>{{cite web|url=http://www.technologyreview.com/tr35/?year=2003 |title=2003 Young Innovators Under 35 |publisher=[[Technology Review]] | year=2003 | accessdate=16 August 2011}}</ref>

ChangeTv changed its name to [[Revver|Revver Inc.]] and unveiled a new website in November 2005 that strove to let creators of short videos earn revenue from their work.<ref>{{cite news| url=https://www.usatoday.com/tech/news/techinnovations/2005-10-30-video-ads_x.htm | work=USA Today | first=Gary | last=Gentile | title=Start-up aims to make online video profitable | date=30 October 2005}}</ref> Revver was one of several user-created video websites unveiled in late 2005, but was the first such website to financially compensate video creators, and is reminiscent of Fairshare.

In December 2006, Clarke left Revver and moved to [[Austin, Texas]].<ref>{{cite web|url=http://newteevee.com/2006/12/20/two-revver-founders-leave/ |title=Two Revver founders leave |accessdate=7 September 2009 |url-status=dead |archiveurl=https://web.archive.org/web/20090917011332/http://newteevee.com/2006/12/20/two-revver-founders-leave/ |archivedate=17 September 2009 }}</ref>  There, Clarke founded a new company, SenseArray, which is a drop-in ad targeting engine based on a proprietary algorithm developed by Clarke.<ref>{{cite web|url=http://sensearray.com/ |title=Sense Array : Welcome |accessdate=29 July 2008 |url-status=dead |archiveurl=https://web.archive.org/web/20080730025150/http://sensearray.com/ |archivedate=30 July 2008 }}</ref> In October 2009, he released Swarm,<ref>{{cite web|url=https://code.google.com/p/swarm-dpl/ |title=Google Code Archive - Long-term storage for Google Code Project Hosting |website=Code.google.com |date= |accessdate=2016-06-05}}</ref><ref>{{cite web|title=Swarm — a New Approach To Distributed Computation|url=http://tech.slashdot.org/story/09/10/11/1738234/Swarm-mdash-a-New-Approach-To-Distributed-Computation?from=rss|publisher=Slashdot}}</ref><ref>{{cite web|url=http://howsoftwareisbuilt.com/2010/01/20/interview-with-ian-clarke-luminary-and-freenet-creator/#swarm |title=Interview with Ian Clarke – Luminary and Freenet Creator |accessdate=12 July 2010 |url-status=dead |archiveurl=https://web.archive.org/web/20100730194315/http://howsoftwareisbuilt.com/2010/01/20/interview-with-ian-clarke-luminary-and-freenet-creator/ |archivedate=30 July 2010 }}</ref><ref>{{cite web|url=http://www.scala-lang.org/node/3485 |title=Swarm - Concurrency with Scala Continuations &#124; The Scala Programming Language |website=Scala-lang.org |date=2009-09-28 |accessdate=2016-06-05}}</ref> a novel approach to distributing computation across multiple computers in a manner largely transparent to the programmer.

In January 2012, Clarke co-founded OneSpot, with the goal of creating "ads that don't suck". Over the next 3 years, he designed a [[real-time bidding]] engine capable of consistently outperforming Google Adwords.<ref>{{Cite web|url=https://vimeo.com/137999578|title=Realtime Bidding: Predicting the future, 10,000 times per second|website=Vimeo|access-date=2016-08-22}}</ref> In March 2012, he open sourced LastCalc,<ref>{{cite web|url=http://lastcalc.com/ |title=LastCalc |website=Lastcalc.com |date= |accessdate=2016-06-05}}</ref> an online calculator he intended to provide an open and more flexible alternative to tools like Google Calculator.<ref>{{cite web|title=LastCalc Is Open Sourced|url=http://science.slashdot.org/story/12/03/10/186201/lastcalc-is-open-sourced|publisher=Slashdot}}</ref>
