In this talk, Uncle Bob describes the three laws of Test-Driven Development and demonstrates the discipline using the Kotlin language, followed by a question and answer round.

Even those who promote software as a craft sometimes fall into the trap of often talking about writing clean code that people can read, yet not placing much emphasis on the skill of reading the code. In this talk, Trisha provides useful advice on how to learn and practice skillful code reading. – Codurance

Katerina Trajchevska, the co-founder of Adara, the global developer network talks about SOLID design principles and how to write better code that is easier to maintain and understand

In this video, we take a piece of crappy Java code with no tests. Our objective is to write tests for it and then refactor to make it better. The code has the most common problems that much larger legacy applications have, like Singletons, static calls, and feature envy. It also has some design problems. Fixing that is quite hard, mainly when we need to write all the tests before we start the refactoring. Another rule: We cannot change production code if it is not covered by tests but quite often, we need to change the production code in order to be able to test it. How to solve this problem? Well, we hope to answer all these questions in this video. – Sandro Mancuso

Upgrade your microservices knowledge by listening to a spirited conversation between two living legends: Sam Newman and Martin Fowler. The two touch upon the main reasons for using or not using microservices, and, if you decide to do use microservices, what else you should change along the way to fully benefit from the switch, plus much more. – GOTO Conferences

Microservices are small services with independent lifecycles that work together. There is an underlying tension in that definition – how independent can you be when you have to be part of a whole? In this talk/tutorial Newman presents the core seven principles that represent what makes microservices tick. After a brief introduction of what microservices are and why they are important, we’ll spend the bulk of the time looking at the principles themselves: * Modelled Around Business Domain * Culture Of Automation * Hide Implementation Details * Decentralize All The Things! * Deploy Independently * Isolate Failure * Highly Observable In terms of learning outcomes, beginners will get a sense of what microservices are and what makes different, whereas more experienced practitioners will get an insight into practical advice into how to implement them. – Devoxx
