Timothy Good Abbott
- Tim Abbott, known by many as "tabbott"
I was co-founder and Chief Technology Officer
of Ksplice; after Oracle's
acquisition of Ksplice, I stayed on for a year as the head of the
Ksplice engineering team at Oracle. Today I'm working on a new startup.
- I spent most of 2008-2012 working
on Ksplice, the software for
updating a running Linux kernel without rebooting, and Ksplice
Uptrack, the subscription service that was running on hundreds of
thousands of production Linux servers as of 2011.
blog archive contains a bunch of great content produced by the
Ksplice engineering team.
- I rewrote all of the Linux kernel's linker scripts to use a set of
macros, so that it's much easier to rename sections.
- I packaged for Debian Sage and
20 of its dependencies. This was a lot of work (I was told that I
needed to find 5 or 6 experienced packagers to make this happen), but
working with the Sage community was a great experience. Unfortunately
delays in the Debian NEW queue followed by my starting Ksplice meant
that this never was particularly useful to users; we eventually
removed the package from Debian since it got quite out of date.
- I started and
led Debian-Athena, a port of
Athena and all its useful software to Debian, with a number of
enhancements. Anders Kaseorg and I ran a distribution on top of
Debian and Ubuntu installed on hundreds of machines across the MIT
campus, and then convinced MIT's official IT organization to adopt it
as the new version of Athena.
- Along with Nelson Elhage, I
developed the Linerva
Project, a secure Linux "dialup" (shell) server at MIT; hundreds
of people logged into the system every day to check their email and do
important coursework before it was handed off to MIT's official IT
organiziation (years after I retired from the project).
- I maintain config-package-dev,
a set of CDBS modules created by Anders Kaseorg and I for
efficiently creating Debian configuration packages.
- I organized the SIPB Virtual Servers
Project until I found people with more time than me to run the
- Anders Kaseorg and I wrote nss_nonlocal, an NSS
module that protects nonlocal accounts from getting access to local
- I wrote pam_mktemp, a PAM
module to create temporary files and set an environment variable to
point to them.
- I worked on scripts.mit.edu,
A SIPB service providing a secure environment for running CGI scripts
out of AFS that now hosts thousands of MIT sites (to this day, MIT's
official webservers only support static content).
- I contribute to Debian, by submitting
bugs and maintaining
- In 2005 and 2006, I ran the
Harvard-MIT Math Tournament, a contest for high school students
run by Harvard and MIT students.
- In 2006, I was Technical Director of Maslab, a student-run IAP
robotics competition course (6.186) focused on autonomous,
vision-based robots navigating an unknown playing area.
- I was Vice Chairman and then Chairman
of MIT's Student Information
Processing Board, the MIT computer club, in 2006-2007. I
instituted a weekly series of technical talks ("Cluedumps") every Fall
and approximately-monthly "hackathons" to work on projects, and
oversaw a series of cleanups and rearrangements of the SIPB office
which resulted in a dramatic increase in its popularity as a
- In 2005, I was Secretary of the MIT
Lecture Series Committee, an organization that shows movies in MIT
lecture halls and uses the profits to bring famous people to speak at
- In 2006, I was the (figurehead) President of the MIT Mystery Hunt.
- During college I lived in Random Hall.
- Ksplice won the grand prize of the 2009 MIT $100K Business Plan
Competition as well as other grants and prizes totaling over $1M.

I normally wouldn't bother highlighting these since they were
basically class project reports, but enough people found them via
Google and then told me they found reading them useful that I'm
leaving them up.

Complexity of the Permanent and Related Problems
I've been mentioned in the Tech, MIT's newspaper, occasionally.
Sometimes they even failed to misquot me.
The following are a set of (generally summer) programs that I
participated in as a high school student and highly recommend.
I attended high school at Thomas Jefferson High School for Science
and Technology (TJHSST, or TJ for short). While there, I benefitted
greatly from a community of peers interested in math and science,
learning much of what I knew by the end of high school from them.
Academic groups at TJHSST for which I was an officer and highly
