Genadi Samokovarov

Code is not essential for running events, even tech events but I'm a coder, and code I did. It helped!

Genadi Samokovarov is going to RubyKaigi in Matsumoto, Japan this year and he's going to talk about RuboCop's Baddest Cop; or, how hard it is (was) to enforce method calls without parentheses. But since you're "my kind of people" (наши хора), you'll get to see the very first edition of this talk, right here in Ruby Banitsa! This talk won't be recorded, come and see it live!

Web Console is a debugging tool bundled with Rails. The most popular feature is a console that is shown in every development error, however, it is a general purpose debugging tool that let you execute Ruby code in any binding as it runs, through its web UI. In this talk, we'll take a look at how the web-console gem is implemented. This includes a deep dive into how exceptions in Ruby work; how to build Ruby bindings for every part of an exception backtrace, so we can execute code in them; how we interact with the DebugInspector and TracePoint C APIs to make this possible and how we supported alternative Ruby implementations like JRuby.

A talk about what happens when a disaster strikes – what happened, what we learned and what we applied to prevent those in the future. In no way a unique story, but one all of us can relate to.
