computer science

i am not naturally talented at math, but have always been fascinated by logic and language. that fascination drove me to choose computer science as my first major, and drives my current interests: compilers, systems programming, and cybersecurity.


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 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.

if labels are your kind of thing, you could call me a kantian with rawlsian tendencies in the political sphere.

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, the lead maintainer of kbsecret, and a sporadic contributor to a few other projects.

other facts

i have a lot of hobbies, but my biggest non-technical ones are bicycling and (ny style) handball. here is my strava.

my favorite genres are ska, punk, hardcore, and all permutations thereof. i'm also partial to hip-hop (especially early east-coast) and some alternative rock. i scrobble on last.fm (let me know if you have a drop-in alternative).

outside of computer science and philosophy, i'm interested in a variety of fields: mathematics, linguistics, classics, latin, psychology, and literature. i run a small IRC channel, #etc on irc.rizon.net, where these are frequent topics of discussion.
