Our lab has an email "code forum" where we share our interesting thoughts or problems pertaining to anything code related. These topics are often relevant to programming experimental protocols and analysing data. Below are a few of the interesting threads we've had thus far, reformatted for easier reading. For more information, contact Peter DiBerardino at pavdiber@uwaterloo.ca.
