In this episode, Arno and Michael take a look at Design by Contract, a programming technique formalized by Bertrand Meyer. The idea is that an interface is more than method signatures - it is also about specifying the expected behavior that implementations must provide. While some languages include direct support for this style of programming, it is a useful mindset when desiging interfaces even without such language features.

This episode is a discussion with Jim Des Rivieres about APIs: How to design good APIs, the role of the documentation/specification in APIs, API evolution and other relevant topics.

For Episode 200 of Software Engineering Radio, Diomidis Spinellis interviews Markus Völter, the podcast’s founder. Markus works as an independent researcher, consultant, and coach for itemis AG in Stuttgart, Germany. His focus is on software architecture, model-driven software development and domain specific languages as well as on product line engineering. Markus also regularly publishes articles, […]

Travis Kimmel and Kevin Goldsmith discuss the correspondence between organizational design and software architecture. Their conversation covers: what Conway’s Law is; Kevin’s experiences in different organizational structures (e.g., Avvo, Spotify, Adobe, and Microsoft) and how those structures influenced the software architecture; what the “Reverse Conway Maneuver” is and how organizations can leverage it; how organizations can evolve existing architectures.

Felienne interviews Marian Petre & André van der Hoek on their book ‘Software Design Decoded’, which contains 66 scientifically backed insights for the design process.

István Lam of Tresorit talks with host Kim Carter about GDPR (the EU General Data Protection Regulation, which has been described as “the most important change in data privacy regulation in 20 years.”)  The discussion covers terminology, planning, implementation, users' rights regarding their personal data, managing personally identifiable information (PII) across an organization, and required documentation. István talks about establishing the intent of different types of PII; when data can be shared or sold, when PII can be stored; storage of backups, and the ability to reveal, modify, or remove all of a customer's PII.

Abhinav Asthana, a founding partner and CEO of the API development tool Postman, discusses API design and testing, where to start, which types of APIs to offer, what tools you can use, what features to expose and what is his favorite API to reference.

Want to know how sleep "resets" your brain? How memories are formed and retained?  Then watch The Benefits of a Good Night's Sleep, embedded below, and learn how sleep balances and regulates the body's vital systems which, in turn, affects declarative and procedural memory.

This short TED-Ed lesson by Shai Marcu is an important topic as school starts and students will soon be staying up late or all night in order to cram for tests and other educational requirements. Marcu goes into detail describing the neurological importance of 8 hours of sleep, but the application is interesting as going to sleep three hours after memorizing math formulas (declarative memory) and one hour after practicing music scales (procedural memory) is the most ideal.

I'm left wondering what I might have accomplished if my sleep and learning patterns were consistent during my formative years...
