introduction

i'm currently a graduate student in columbia university's physics department studying applications of machine learning to problems in biological physics (expected graduation summer 2008). i have a masters in applied physics from columbia and a bachelors in electrical engineering from boston university. please see my resume for more project and background information.

this site serves several purposes, from presenting and organizing my current research and teaching efforts to publishing code and tips that i hope others will find useful. eventually i'd like to get some mac/linux/unix resources and tutorials posted in an organized format so others can benefit from the vast amount of time i've spent discovering things.

latest tips

i'd like to organize this a bit more, but here are my latest geek tips:

2008.07.16 macosx: opendiff uses FileMerge to visualize diff between two files
2008.07.16 python: fcn(*x) explodes elements of x before passing to function fcn; useful for zip(*l) to rearrange list of tuples
2008.07.16 python: zip(l1,l2) returns list of tuples, where each tuple conains i-th element from each argument sequence
2008.07.12 iphone: with iphone 2.0, hold down the home button and press the lock button to take a screenshot
2008.07.11 macosx: to speed up mail.app, try sqlite3 ~/Library/Mail/Envelope\ Index and then vacuum subjects; followed by ctrl-d to quit

for now, see all in the tips file. prettier format coming soon.
