The University of Minnesota's Software Engineering Center and Cprime are pleased to bring you the 15th annual Code Freeze symposium. This year's theme, Observability, will offer thought provoking presentations from our three keynote speakers, Casey Rosenthal (Verica), Charity Majors (Honeycomb), and Bonnie Holub (Teradata), as well as several engaging breakout sessions. The chairs for this year's program, Stephen Taylor of Cprime and Sanjai Rayadurgam from the University of Minnesota, have plans in store that promise to make this year's Code Freeze symposium another successful event. We look forward to seeing you there!

Our theme: Observability

Increasing complexity of software and infrastructure, the merging of development and operations, and the requirement of teams to have better insight into what's going on "under the hood" have fueled the demand for greater visibility into the performance and reliability of systems. Observability, as a premise and practice, has emerged to help bridge the gap between effective monitoring and relevant insight. Code Freeze 2020 will promote "20/20" vision into software systems. We will explore externalization of states in the context of software systems, technical debt, data, devops, machine learning and more. We will examine observability as a property and a practice and explore its adoption from a cultural and a process perspective.

Our keynote speakers:

Casey Rosenthal, CEO and Cofounder of
As an Executive Manager and Senior Architect, Casey manages teams to tackle complex systems, architect solutions to difficult problems, and train others to do the same. He seeks opportunities to leverage his experience with distributed systems, artificial intelligence, translating novel algorithms and academia into working models, and selling a vision of the possible to clients and colleagues alike. His superpower is transforming misaligned teams into high performance teams, and his personal mission is to help people see that something different, something better, is possible. For fun, Casey models human behavior using personality profiles in Ruby, Erlang, Elixir, Prolog, and Scala.
Charity Majors, Engineer/Cofounder,
Charity Majors is the co-founder and CTO of, a tool to help software engineers understand what happens when their code meets production. Charity ran infrastructure at Parse and was an engineering manager at Facebook. She started Honeycomb to bring engineers the observability tooling they need for the era of distributed systems. Charity is the co-author of Database Reliability Engineering (O'Reilly), and is devoted to creating a world where every engineer is on call and nobody thinks on call sucks.
Bonnie Holub, Practice Lead, Data Scientist, Teradata.
Bonnie K. Holub holds a Ph.D. in Artificial Intelligence and has spent her career correlating disparate sets of Big Data for actionable results. She leads Teradata’s Data Science Business Industries Outcomes team in the Americas. Dr. Holub has served a variety of roles including VP Talent Analytics at Korn Ferry, Master Data Scientist at Cognizant, Analytics Director at PwC, and Enterprise Data Warehouse Program Manager at UCare Health Insurance. She has been an entrepreneur founding several companies, the most successful of which is Adventium Labs, an AI and secure software research organization. She has been a tenured professor at the graduate level and been involved with the founding of several successful Big Data, Data Science, and AI programs at various universities.

Conference sessions will take many forms: presentation, demonstration, and hands-on. We will have breakout sessions from experts discussing the premise and practice of observability.

Registration: Cost for the full day is $130 for the general public and $100 for alumni of the Software Engineering (MSSE) and Computer Science (CS) programs. Register and pay for the attending the event here.
Parking: Parking is not included in registration fee. The University Ramp, located on University Avenue next to McNamara Alumni Center, charges $12 normal daily rate. Here is an overview map of various parking options on the East Bank. (the venue is opposite to the southwest corner of TCF Bank Stadium).
