In this video, Uncle Bob discusses the importance of software design and architecture, and how these concepts have evolved over time. He demonstrates how software is present in many everyday objects, and how it has the potential to kill people if it is not designed and implemented correctly. He argues that we need to take measures to ensure that our profession remains ethical and responsible, and that we continue to learn and grow as an industry.

  • 00:00:00 Uncle Bob discusses the importance of software and its role in our lives, and how it has evolved over time. He then goes on to discuss how software is running on his body, and how many processors are present. He also discusses how many computers are present in the room, and how speakers include processors.
  • 00:05:00 The speakers discuss the hidden software running in many everyday objects, from cars to sewing machines. They warn of the dangers of this software, which has the potential to kill people.
  • 00:10:00 The speaker discusses the importance of programmers and the potential for accidents caused by programmer negligence. He suggests that we need to take measures to ensure that our profession remains ethical and responsible.
  • 00:15:00 In 1946, one programmer wrote the first code for an electronic computer. In 2019, there are millions of programmers in the world. The doubling rate for programmers is five years every five years, and by the year 8 billion, half of them will have less than five years experience. This keeps the industry in a state of perpetual inexperience, and prevents growth and intellectual development.
  • 00:20:00 Robert C. Martin discusses how architecture is about understanding the intent of a system, and how it can be seen in the layout of a software application's directory structure. He also points out that architecture should be about communicating this intent to the user, and not just hiding the system's internals.
  • 00:25:00 In "ITkonekt 2019 | Robert C. Martin (Uncle Bob), Clean Architecture and Design," Robert C. Martin discusses Uncle Bob's seminal work on object-oriented software engineering, which has been widely read and appreciated by software professionals. Jakob S'en's book, "Structure and Interpretation of Computer Programs," is highly recommended for software developers who want to improve their understanding of code structure and design.
  • 00:30:00 In this video, Uncle Bob Martin discusses the basics of use cases and how they are represented in code. He also describes two types of boundary interfaces and how they are similar to Java interfaces. Finally, Jakob Sinned discusses how data must enter and exit use cases in order to ensure proper automation.
  • 00:35:00 In this video, Uncle Bob Martin discusses the design principles behind functional programming languages, such as Scala and Go. He also discusses how to test code in these languages, noting that test-driven development is important in Java and C#, but less so in Go. He concludes the video by discussing service-oriented architecture and microservices.
  • 00:40:00 The ITkonekt 2019 video by Robert C. Martin covers the concept of an "interactor" that begins to inspect a system and understand its interaction, then controls the data flow between the various entities. Martin also discusses the use of model-view-controller (MVC) in web development, noting that it has become "bastardized" over time.
  • 00:45:00 In this video, Uncle Bob discusses the Clean Architecture model, which emphasizes separating the functionalities of a system into discrete, self-contained "modules." The presenter then demonstrates how this model enables the data to be sent to and displayed on an output boundary, without any dependencies crossing an architectural boundary.
  • 00:50:00 In this video, Uncle Bob discusses the importance of design frameworks, Clean Architecture, and the role of the database in a system. He argues that the database should not be the center of a system, and that architects and designers should use an ORM to save code complexity.
  • 00:55:00 This video is a brief introduction to the ITkonekt 2019 conference, which is being hosted by Uncle Bob. Uncle Bob discusses the design and implementation of a wiki application called "Fitness" which allowed businesspeople and QA people to write tests with input data and expected output data. Fitness was eventually migrated to a relational database and implemented using a test-driven development approach. A customer requested that the data be stored in the database, and after demonstrating how the data was currently being stored, Uncle Bob and his team showed the customer how to implement the same functionality using My Sequel.

01:00:00 - 01:10:00

In this video, Uncle Bob Martin talks about the importance of clean architecture and design. He discusses how deferring decisions until the last responsible moment can help minimize the number of decisions not made. He also talks about how testing can be used to ensure that smaller parts of a system behave properly.

  • 01:00:00 In this video, Uncle Bob Martin discusses the importance of designing systems with a "clean architecture." He talks about how deferring critical decisions until the last responsible moment can help minimize the number of decisions not made. He also discusses how testing can be used to ensure that smaller parts of a system behave properly. In the last few minutes of the video, someone asks a question.
  • 01:05:00 In this video, Uncle Bob Martin discusses the importance of communicating intent with a software folder structure. He also mentions that frameworks can be a problematic tool, as their authors may not have your interests in mind and may not understand your problems. He advises Architects and Lead Designers to be very skeptical of a framework's relationship with their code, and to be aware of how much they bind to the framework and how to use it safely.
  • 01:10:00 In this video, Uncle Bob Martin discusses the benefits of using a dependency injection framework, and points out that there is no need to test a database if it's purchased. He also discusses the importance of using point weight in order to avoid integration problems.
