Programming today means programming alongside hundreds of fellow students, thousands of fellow professional software engineers, or millions of fellow open-source developers sharing their code online. In this talk, I will describe several interactive systems I have built that exploit the structure in large volumes of peer-produced code to help individual programmers learn how to write more correct, readable code.<br class=""><br class="">These systems are made possible by code demography, which I define as statistics, algorithms and visualizations that help people comprehend and interact with population-level structure and trends in large code corpora. The key to my approach is designing or inferring abstractions that capture critical features and abstract away variation that is irrelevant to the user. Code demography can reveal strategically diverse sets of aligned code examples which, according to theories of human concept learning, help people learn, i.e., construct mental abstractions that generalize well.<br class=""><br class="">I will focus this talk on two families of systems that use program analysis, program synthesis, and visualization to either power active data-driven teaching in large programming classrooms or passive knowledge sharing within developer communities. Some of these systems have been integrated into UC Berkeley’s largest introductory programming class, which regularly enrolls over 1500 students. I will conclude with my vision for how the techniques of code demography can be generalized to help data scientists and enable new data-driven programming paradigms.<br class=""><br class=""> </span></span><br class=""></font><b class="" style="color: rgb(33, 33, 33); font-family: Roboto, Helvetica, Arial, sans-serif; font-size: 14px;">Bio:</b></div><div class=""><span id="docs-internal-guid-8bdccc40-716c-e22d-6a5f-d3d1c5863489" class=""><div class="" style="line-height: 1.38; margin-top: 0pt; margin-bottom: 0pt;"><span class="" style="font-size: 14px;"><i class=""><span class="" style="color: rgb(33, 37, 41); background-color: rgb(255, 255, 255); font-variant-ligatures: normal; font-variant-position: normal; font-variant-numeric: normal; font-variant-alternates: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">Elena Glassman is an EECS postdoctoral researcher at UC Berkeley, in the Berkeley Institute of Design, funded by the </span><a href="https://excape.cis.upenn.edu/" class="" style="text-decoration: none;"><span class="" style="color: rgb(102, 102, 178); background-color: rgb(255, 255, 255); font-variant-ligatures: normal; font-variant-position: normal; font-variant-numeric: normal; font-variant-alternates: normal; font-variant-east-asian: normal; text-decoration: underline; -webkit-text-decoration-skip: none; vertical-align: baseline; white-space: pre-wrap;">NSF ExCAPE Expeditions in Computer Augmented Program Engineering</span></a><span class="" style="color: rgb(33, 37, 41); background-color: rgb(255, 255, 255); font-variant-ligatures: normal; font-variant-position: normal; font-variant-numeric: normal; font-variant-alternates: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;"> grant and the Moore/Sloan Data Science Fellowship from the </span><a href="https://bids.berkeley.edu/" class="" style="text-decoration: none;"><span class="" style="color: rgb(102, 102, 178); background-color: rgb(255, 255, 255); font-variant-ligatures: normal; font-variant-position: normal; font-variant-numeric: normal; font-variant-alternates: normal; font-variant-east-asian: normal; text-decoration: underline; -webkit-text-decoration-skip: none; vertical-align: baseline; white-space: pre-wrap;">UC Berkeley Institute for Data Science (BIDS)</span></a><span class="" style="color: rgb(33, 37, 41); background-color: rgb(255, 255, 255); font-variant-ligatures: normal; font-variant-position: normal; font-variant-numeric: normal; font-variant-alternates: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">.
