Adam’s other interests include modern history, music, and martial arts. Topics of Discussion: [2:10] Adam talks about how he got his start in code metrics 25 years ago and why he’s discovered that it’s so hard to write good code. [3:48] What are the other book ideas Adam has to add to his existing four? [4:53] What motivated Adam to write Your Code as a Crime Scene and what is the premise? [9:02] When assembling the data, relevance, as well as quality, are both important. [10:29] Cyclomatic complexity is an old metric, as are many others, that is not quite tangible or relevant. [11:58] Why Adam prefers to look at code health vs. code quality. [13:26] The process is slightly different when looking at code health for existing code vs. writing new code. [15:23] How does CodeScene aid in the pull request process? [18:31] CodeScene integrates with your version control repository and work tracking tools to find where bugs were introduced. [22:22] Is CodeScene meant to be a standalone tool or can it work alongside many of the other tools on the market? [24:57] Adam’s rules of thumb for those getting started in software systems. [28:12] Why Adam’s preferred method of delivering software architecture has changed over the years. [30:36] What are the steps for implementing CodeScene into a codebase?

There’s no way I can really take a software system and pull it out and turn it around and inspect it for flaws.” — Adam [6:34] “What I’m most interested in is trends; so are we moving in the right direction or the wrong direction?” — Adam [15:14] “My experience, from working with all of these companies, is that pull requests and code reviews, in general, are extremely valuable… but they also tend to become a bottleneck in practice.” — Adam [16:10] “A surprise is simply one of the most expensive things you can put into a software architecture.” — Adam [30:15] “While these mechanics are simple, information is only good when acted upon.” — Adam [31:20] Adam: Website | Twitter | LinkedIn
