Editing Andrew Tridgell (section)

==Projects==
Tridgell was a major developer of the Samba software, analyzing the [[Server Message Block]] protocol used for [[Workgroup (computer networking)|workgroup]] and network file sharing by [[Microsoft Windows]] products. He developed the [https://talloc.samba.org/talloc/doc/html/index.html {{not a typo|talloc}}] hierarchical memory allocator, originally as part of Samba.

For his PhD dissertation, he co-developed [[rsync]], including the rsync algorithm, a highly efficient [[file transfer]] and [[File synchronization|synchronisation]] tool. He was also the original author of [[rzip]], which uses a similar algorithm to rsync. He developed spamsum,{{clarify|and what would that be?|date=June 2016}} based on [[locality-sensitive hashing]] algorithms.<ref>{{cite journal|author=Jesse Kornblum|title=Identifying almost identical files using context triggered piecewise hashing|url=http://dfrws.org/2006/proceedings/12-Kornblum.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://dfrws.org/2006/proceedings/12-Kornblum.pdf |archive-date=2022-10-09 |url-status=live|journal=DFRWS|year=2006|access-date=23 February 2014}}</ref>

He is the author of [[KnightCap]], a [[reinforcement learning|reinforcement-learning]] based [[chess engine]].

Tridgell was also a leader in [[Hacker (hobbyist)|hacking]] the [[TiVo]] to make it work in Australia, which uses the [[PAL]] video format.<ref>{{Cite web |url=http://www.samba.org/~tridge/tivo-ethernet/ |title=TiVo Ethernet |first=Andrew |last=Tridgell |access-date=17 August 2012 |archive-date=14 January 2012 |archive-url=https://web.archive.org/web/20120114183142/http://www.samba.org/~tridge/tivo-ethernet/ |url-status=dead }}</ref>

In April 2005, Tridgell tried to produce free software (now known as [[SourcePuller]]) that interoperated with the [[BitKeeper]] source code repository. This was cited as the reason that BitMover revoked a license allowing [[Linux]] developers free use of their BitKeeper product.<ref>[https://lwn.net/Articles/169178/ git [LWN.net&#93;<!-- Bot generated title -->]</ref> [[Linus Torvalds]], the creator of the Linux kernel, and Tridgell were thus involved in a public debate about the events, in which Tridgell stated that, not having bought or owned BitKeeper – and thus having never agreed to its license – he could not violate it, and was analyzing the protocol ethically, as he had done with Samba. Tridgell's involvement in the project resulted in Torvalds accusing him of playing dirty tricks with BitKeeper.<ref>{{Cite news |url=https://www.theregister.co.uk/2005/04/14/torvalds_attacks_tridgell/ |title=Torvalds knifes Tridgell: Kernel source row turns nasty |first= Andrew |last=Orlowski |date=14 April 2005 |work=[[The Register]]}}</ref> Tridgell claimed his analysis started with simply [[telnet]]ing to a BitKeeper server and typing <code>help</code>.<ref>{{Cite web |url=http://www.groklaw.net/articlebasic.php?story=20050421023821174 |title=Groklaw – Tridge Speaks<!-- Bot generated title --> |access-date=5 September 2007 |archive-url=https://web.archive.org/web/20110527150705/http://www.groklaw.net/articlebasic.php?story=20050421023821174 |archive-date=27 May 2011 |url-status=dead }}</ref>
