Theodore Yue Tak Ts'o (Chinese:曹子德; born 1968) is an Americansoftware engineer mainly known for his contributions to theLinux kernel, in particular his contributions tofile systems. He is the secondary developer and maintainer ofe2fsprogs, the userspace utilities for theext2,ext3, andext4 filesystems, and is a maintainer for the ext4 file system.
Ts'o graduated fromMIT with a degree incomputer science in 1990, after which he worked in MIT's Information Systems (IS) department until 1999. During this time he was project leader of theKerberos team.
In 1994, Ts'o created the/dev/randomLinux device node and the corresponding kernel driver, which was Linux's (andUnix's) first kernel interface that provided high-quality cryptographic random numbers to user programs.[1]/dev/random works without access to ahardware random number generator, allowing user programs to depend upon its existence. Separatedaemons such asrngd take random numbers from such hardware and make them accessible via/dev/random.[2] Since its creation, interface/dev/random is used in Linux,FreeBSD,macOS, andSolaris systems.[3]
After MIT IS, Ts'o went to work forVA Linux Systems for two years. In late 2001 he joinedIBM, where he worked on improvements in the Linux kernel's performance and scalability. After working on areal-time kernel at IBM, Ts'o joined theLinux Foundation in late 2007 for a two-year fellowship. He initially served as Chief Platform Strategist,[4] before becomingChief Technology Officer in 2008.[5] Ts'o also served as Treasurer forUSENIX until 2008, and has chaired the annualLinux Kernel Developers Summit.
In 2010 Ts'o moved toGoogle,[6] saying he would be working on "kernel, file system, and storage stuff".[7]
Ts'o is aDebian Developer, maintaining several packages, mostly filesystem-related ones, including e2fsprogs since March 2003. He was a member of the Security Area Directorate for theInternet Engineering Task Force, and was one of the chairs for theIPsecworking group. He was one of the founding board members for theFree Standards Group.[citation needed]
In July 2023, Ts'o joined RESF's Board of Directors, which encompasses theRocky Linux project.[8]
Ts'o was awarded theFree Software Foundation's 2006Award for the Advancement of Free Software.[9]
The Linux Foundation (LF), the nonprofit organization dedicated to accelerating the growth of Linux, today announced that Linux kernel filesystem maintainer Ted Ts'o is joining the organization as a Fellow and chief platform strategist.
Theodore 'Ted' T'so has moved to Google, leaving his position as Linux Foundation's Chief Technology Officer.
I'm going to be working on kernel, file system, and storage stuff. Ext4 will definitely be one of the first things I'll be working on,
