The annual nationwide survey of CS departments (a.k.a. “Data Buddies”) is now live: https://cerp.co1.qualtrics.com/jfe/form/SV_9vFybdrfLKUkVcq/?id=yale_csThis survey measures retention and persistence among CS students, including undergraduate majors, non-majors, and graduate students. It is the main tool that the department will be using to both gauge our diversity efforts, and compare against peer CS departments.
It is run externally by the Computing Research Association, which only provides aggregate data. At no point will we have access to individual answers or identities.
We will be using the survey results to set and prioritize future department initiatives, so this is a great chance to have your voice heard. Please fill it out!
You asked in your voicemail if I have any advice for your students. The most important thing for me was to bring a growth mindset and learning-focused approach to my work. I gave a talk about this in 2015 and wrote it up on my blog here. In the years since, that thinking has really held up for me. As professional programmers, our work is mostly operating on the boundary of our skills and comfort - mostly doing things we don't yet know how to do, and rarely repeating work that we've done before. That makes for a very fun career, in my opinion, but only if you can get comfortable in that challenging setting.My coursework in Astronomy & Physics at Yale wasn't directly applicable to my work as a software engineer today (this was before all astronomy was in Python, and the CS course I took was half FORTRAN and half C++), but it helped me learn how to struggle and succeed in a way I hadn't experienced before college. These days, I'm still working as a software engineer at a startup (Pilot.com), where I was engineer #2. I'm shifting focus to LLM optimization to see what this new technology can do for us - another opportunity to stretch myself and learn.
Here is a practice final exam and practice final solutions. There will be no questions on R or idem potence.
Here are the important concepts from Stamp:
Shell scripts: I might ask you to write a shell script. You should know the for loop.
If your grade on the final exam is higher than your lower midterm grade, it will replace that grade. The quality of mercy is not strained.
