Theodore Y. "Ted" Ts'o (born 1968) is a software engineer mainly known for his contributions to the Linux kernel, in particular his contributions to file systems. He is the primary developer and maintainer of e2fsprogs, the userspace utilities for the ext2 and ext3 filesystems, and is a maintainer for the ext4 file system. == Biography == Ts'o graduated from MIT with a degree in computer science in 1990, after which he worked in MIT's Information Systems (IS) department until 1999. During this time he was project leader of the Kerberos V5 team. In 1994, Ts'o created /dev/random Linux device node and the corresponding kernel driver, which was Linux's (and Unix's) first kernel interface that provided high quality cryptographic random numbers to user programs. /dev/random works without access to a hardware random number generator, allowing user programs to depend upon its existence. Separate daemons such as rngd take random numbers from such hardware and make them accessible via /dev/random. Since its creation, /dev/random and /dev/urandom have become standard interfaces on Unix, Linux, BSD and Mac OS systems.After MIT IS Ts'o went to work for VA Linux Systems for two years. In late 2001 he joined IBM, where he worked on improvements in the Linux kernel's performance and scalability. Then in late 2007 he moved to the Linux Foundation, where he initially served as Chief Platform Strategist before he became Chief Technology Officer in 2008. Ts'o also served as Treasurer for USENIX until 2008, and has chaired the annual Linux Kernel Developers Summit. In 2010 Ts'o moved to Google,〔(【引用サイトリンク】 Ted T'so moves to Google )〕 saying he would be working on "kernel, file system, and storage stuff."〔(【引用サイトリンク】 Proud to be a Googler )〕 Ts'o is a Debian Developer, maintaining several packages, mostly filesystem-related ones, including e2fsprogs since March 2003. He was a member of the Security Area Directorate for the Internet Engineering Task Force, and was one of the chairs for the IPsec working group. He was one of the founding board members for the Free Standards Group. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Theodore Ts'o」の詳細全文を読む スポンサード リンク
