 Problem Set #1 was released on Wednesday, April 2nd. It is due at 12:50pm (at the start of class) on Friday, April 11th.
 Unless you are an SCPD student, please turn
in hardcopies of your problem set submissions. You can
turn them in either in class, at Mehran's office (slide them
under the door if he's not in) or at your graders office hours
(you'll find out who your grader is once you get your first
problem set returned).
Please note that (except for SCPD students) we do not accept submissions via email as we've had too many problems in the past with corrupt files, email message bounces, late delivery, etc.
SCPD students (only) may submit problem sets via email, via the SCPD courier, or in class.
 If you are interested in writingup your problem sets using
the LaTex system (this is purely optional), there is a short
intoduction to LaTex available as a
PDF document, and you can also obtain the
original LaTex file that was used to generate that
PDF (so you can see an example of LaTex source).
If you would like to write your solutions for the Problem Sets in LaTex, you might find it useful to start with this LaTex template file for Problem sets.
An online LaTeX editor and compiler is available at https://www.writelatex.com/.
 For those of you using LaTex to write your assignments, former CS109 student Joe Delgado has written a nunber of snippets for Latex in Sublime, which he has made available on github. You an find a repo of statistical snippets at: https://github.com/djoeman84/Latexstatisticalsnippets and a repo for more general math snippets at: https://github.com/djoeman84/LatexMathSnippets.
