19:45 〜 20:15 Pattern Languages for Rubyists Hiroki Yoshioka

Software development is a complex process and experience and knowledge are very valuable. Pattern language is a form of knowledge. This presentation will explain what the pattern language is, how it is brought to the software industry, and why it matters in software development.


Hiroki Yoshioka (Iro) is an agile coach / web developer, working for KRAY Inc. He wrote "Rails Development Patterns" for AsianPLoP 2015, a conference on pattern language. His other works include: "The Metric talks or not", RubyKaigi 2013, "ブラック・アジャイルによろしく", @IT, 2013.

20:15 〜 20:45 Writing (Nearly) Bug-Free Code Don Werve

Computers and programmers often have heated disagreements about what each of them is supposed to be doing, which rarely works out in favor of the programmer. We call these disagreements 'bugs', and they are a constant source of ruined vacations and endless stress. The thing is, bugs don't just happen. We programmers are responsible for creating them in the first place, and rather than spending massive amounts of time removing bugs from code that we've written, what we really want is some way to avoid writing bugs to begin with. So, in this talk, we will combine the art of programming with the science of cognitive psychology, and emerge with a set of simple, proven techniques that we can use to craft nearly bug-free software from the get-go.


Although originally designed by Apple in California as a durability-testing device for Macbooks, Don has spent the past six years working around the world as a software engineer and back-pocket CTO, helping companies solve tough team management and scaling issues. Don lives in Tokyo, and spends his spare time reading too many books, creating new forms of deliciousness in his kitchen, and searching for new and creative ways to injure himself with sporting equipment.
