Nicolas will be the first to tell you that the version of Stack Overflow he helped to create began as a clone. It developed into a very popular site on RuNet and through persistent emails, Nic was able to find a way to make it an official part of the Stack family. Nic talks a bit about the unique culture of SO's Russian community and how each regional version of SO, from English to Spanish to Japanese, has developed its own etiquette and approach to moderation and Q&A. Nic and Sara also share some updates on their love of Jupyter Notebooks and how they make it easy to combine blogging with data analysis and presentation. Shout out to our life boat badge of the week, Aliaksandr Kavalenka , for answering the question: How to use DatePickerDialog in Kotlin?
