about me

q & a

q: who are you?
a: my name is william. some friends call me will. some (mostly on the internet) call me yossarian.

q: what do you do?
a: i do research and engineering at trail of bits and write open source software. i once studied philosophy and computer science.

q: why is this site simple/ugly/lowercase?
a: the main question is whether the stuff is literature or not.

q: are you available for hire?
a: please see my cv for my status. i do not respond to third-party recruiters, and i am not officially represented by any recruiters. i am not interested in working on cryptocurrencies or for cryptocurrency companies. i do not freelance.

computer science

i am not naturally talented at math, but have always been fascinated by logic and language. that fascination drives my current interests: compilers and program analysis, systems programming, and cybersecurity.

i believe strongly in software engineering: i like writing correct and reliable software, especially for other programmers. i think that security engineering and quality engineering are the same thing.

some buzzkeywords: automated vulnerability reasoning, static and dynamic instrumentation, multi- and inter-representational analysis program synthesis, applied cryptography, package management.


logic and language are topics of interest for me in philosophy as well, but ethical philosophy appeals to me most of all. in particular, i am interested in theories of rights and duties, as well as the problems of coercion and exploitation as they concern and (de)legitimize choice. i am also interested in moral education as it applies to beneficence, charity and authenticity (of the good/bad faith kind), and public discourse.

open source work

i spend a lot of time tinkering in the open source community, both on my own projects and on larger ones. in particular, i am a member of the homebrew development team and an active professional and hobby contributor to several other projects. most of my professional work is open source, and i like it that way. i am not interested in professional work that is primarily proprietary, although i am willing to work in a hybrid setting.

other facts

i have a lot of hobbies, but my biggest non-technical ones are bicycling, film photography (portraiture), chess, and (ny style) handball.

outside of computer science and philosophy, i'm interested in a variety of fields: mathematics (discrete), linguistics, classics (greco-roman), latin (classical), psychology (will, action), and literature (most kinds).

i organize brothercon, a gathering for people who like terrible NYC dollar pizza.

i do a regular online radio show on a friend's internet radio server.
