API Change Management with Aidan Cunniffe
APIs within a company change all the time. Every service owner has an API to manage, and those APIs have upstream and downstream connections. APIs need to be tested for integration points as well as for their “contract”, the agreement between an API owner and the consumers of that API. Aidan Cuniffe is the founder of Optic, a product built for API change management. He joins the show to explain why there is an opportunity for such a product, and the market dynamics of the space of API testing and change management.

Hyperparameter Tuning with Richard Liaw
Hyperparameters define the strategy for exploring a space in which a machine learning model is being developed. Whereas the parameters of a machine learning model are the actual data coming into a system, the hyperparameters define how those data points are fed into the training process for building a model to be used by an end consumer. A different set of hyperparameters will yield a different model. Thus, it is important to try different hyperparameter configurations to see which models end up performing better for a given application. Hyperparameter tuning is an art and a science. Richard Liaw is an engineer and researcher, and the creator of Tune, a library for scalable hyperparameter tuning. Richard joins the show to talk through hyperparameters and the software that he has built for tuning them.

Software and the Law with Mark Radcliffe
As software permeates our lives, there are an increased number of situations where the legal system must be designed to account for that software. Whether the issues are open source licensing, cryptocurrencies, or worker classifications, software overlaps heavily with the law. Just as software is crafted by engineers, the legal structure around software is crafted by lawyers. There are large law firms that have built their business by knowing how to navigate these software and business questions. Mark Radcliffe is a lawyer who has been working with software companies for decades. He joins the show to talk about the intersection of software and the law, which we discuss from multiple points of view.

Data Version Control with Dmitry Petrov
Code is version controlled through git, the version control system originally built to manage the Linux codebase. For decades, software has been developed using git for version control. More recently, data engineering has become an unavoidable facet of software development. It is reasonable to ask–why are we not version controlling our data? Dmitry Petrov is the founder of Iterative.ai, a company for collaborating and version controlling data sets. Dmitry joins the show to talk about how data version control works, and Iterative.ai, the company he is building around dataset management and collaboration.

Release Apps with Tommy McClung
Every software company works off of several different development environments–at the very least there is staging, testing, and production. Every push to staging can be spun up as an application to be explored, tinkered with, and tested. These ad hoc spin-ups are known as release apps. A release app is an environment for engineers to play with, and potentially throw away or promote to production. Release apps have been made easier due to technologies such as infrastructure-as-code, continuous integration, and Kubernetes. Tommy McClung is the co-founder of Release App, a company that makes it easy to spin up release environments for your software. Tommy joins the show to discuss release workflows, and his work building Release App.

SuperAnnotate: Image Annotation Platform with Vahan and Tigran Petrosyan
Image annotation is necessary for building supervised learning models for computer vision. An image annotation platform streamlines the annotation of these images. Well-known annotation platforms include Scale AI, Amazon Mechanical Turk, and Crowdflower. There are also large consulting-like companies that will annotate images in bulk for you. If you have an application that requires lots of annotation, such as self-driving cars, then you might be compelled to outsource this annotation to such a company. SuperAnnotate is an image annotation platform that can be used by these image annotation outsourcing firms. This episode explores SuperAnnotate, and the growing niche of image annotation. Vahan and Tigran Petrosyan are the founders of SuperAnnotate, and join the show for today’s interview.
