Also, many of the technical skills she describes are taught in workshops by the D-Lab at Berkeley. Take advantage! And if you’re not at Berkeley, do some research to find out if your university has a group that provides such workshops.
Jessica also has a blog where she frequently discusses topics related to academia and the tech world.
