In the software industry, it’s common to be on a project with an aggressive timeline. Even if the schedule was correct, plans don’t always go the way you expect and become off track. Teams end up working more extended hours, try to add people to the project or make other heroic efforts to try and “save the day’ and finish on time. In my experience, rarely have those efforts worked and when it did, the team was so burned out it took several weeks to get motivated to tackle another project. There should be a better way to complete projects on time, so teams feel a sense of accomplishment and are excited to take on the next project. In this session, we discuss some key behaviors you can do with your team, unlocking a better way to work to help the team succeed.

pandas is more than 10 years old now. In this time, it became almost a standard for building data pipelines and perform data analysis in Python. As the popularity of the project grows, it also grows the number of projects that depend or interact with pandas. This talk will cover this ecosystem of projects around pandas, mainly in the prespective of scalability and performance. Discussing for example how projects like Arrow are key for the future of pandas, or how Dask is overcoming pandas limitations. In a first part, the talk will focus on pandas itself, its components, and its architecture. This will give the required context for a second part, that will explain related projects, how they interact with pandas, and what the whole ecosystem can offer to users.

Service oriented systems have become hugely popular, and the golden age of the monolith has past. Sometimes these services can be fantastic, and other times not so much. Learning how to evaluate APIs and identify problem areas before jumping head first into development can save teams frustration, time, and money. This session will walk through evaluating an API, best practices, and red flags, all from the standpoint of a developer consuming them. No matter your experience level, you’ll leave with the skills to effectively tackle your next API.
