  • Building Command Line Interfaces with Ruby - Matt Buck (doors open @ 6:30pm)

    # Building Command Line Interfaces with Ruby Building a great CLI requires much of the same work as building a great GUI: the interface should be simple to understand and easy to use. Luckily for the modern Rubyist, there are a plethora of gems for building outstanding command line interfaces. Based on Voxable's work building Expando, a CLI for building natural language understanding models, we'll explore some of the considerations and options when building CLI's in Ruby. We'll also discuss under what circumstances Ruby might not be the best option (gasp!) and which alternatives to consider. # About the Speaker Matt has been programming computers since his parents first brought home an old Commodore 64 when he was ten years old. A graduate of the University of Texas, he's spent over a decade working with a number of high-profile engineering teams in the Austin area. In 2015, Matt launched Voxable, a conversational interface agency, with his fiancé. On a mission to help humans and computers better understand each other, he spends his time leading development efforts at Voxable, creating open source tools for building Conversational User Interfaces, and speaking about speaking to machines. # Sponsors Thank you to Capital Factory for sponsoring the space and to Toptal for sponsoring the food.

  • Text Processing w. Ruby - Hal Fulton (doors open @ 6:30pm)

    Love it or hate it, we all do text processing sometimes. To do it well in Ruby, it helps to understand strings, arrays, regexes, I/O, and more topics. I'll remind you of things you forgot and teach you some new things as well. I'll end by presenting my project Livetext and showing its motivation and some of my own use cases. # About the Speaker Hal Fulton is the author of The Ruby Way, now in its third edition. He is working on a book Elixir for the Rubyist, to be released later in 2018. He has two degrees in computer science and more than 20 years in the industry, including a few years of teaching. His short stories have been rejected by some of the finest magazines in the country. On rare occasions he plays chess and piano, both incredibly badly. He spends his spare time putting Slinkys on escalators and passing counterfeit bills to tourists.

  • Is Elixir the Next Ruby? - Hal Fulton (doors open @ 6:30pm)

    About the talk: Ruby is still my favorite language, but it’s not the only language in the world. Lately I have been getting into Elixir, which is partly inspired by Ruby (both the syntax and the community). It’s been an important addition to my mental toolbox, and I think it’s going to be bigger in the future. Hal Fulton is the author of The Ruby Way, now in its third edition.
