 ar a quick word from our sponsor. \n\n19:10 〜 19:40  How Reasonable Dec
 isions Created a Security Incident - \nPaul McMahon \n\nA security incide
 nt exposed the resumes of 460 job seekers. The surprising part? There was
  no single bug or obviously wrong decision to blame. Instead\, a series o
 f reasonable technical choices interacted in unexpected ways\, creating a
  vulnerability that went unnoticed until it was too late. In this talk\, 
 I’ll share how the incident was discovered\, investigated\, and resolve
 d\, along with practical lessons on security\, complexity\, and hidden as
 sumptions in Ruby on Rails applications.\n\nProfile\n\nPaul McMahon is th
 e founder of TokyoDev and has been building Ruby on Rails applications fo
 r over 20 years. He also founded the Tokyo Rubyist Meetup in 2010\, and p
 reviously co-founded the event platform Doorkeeper. Today he runs TokyoDe
 v\, helping international software developers advance their careers in Ja
 pan\, while staying hands-on with the development and operation of the si
 te’s Rails application.\n\n19:40 〜 20:00 Rubyist show and tell\n\nDo 
 you have a cool snippet of Ruby code that you'd like to share\, but it do
 esn't warrant an entire presentation? A challenge with your Ruby applicat
 ion you've been struggling with\, and would like some advice? A helpful l
 ibrary or tool you've come across? This is your chance to share it.\n\nFo
 r those who'd like to participate\, you'll have up to five minutes. There
 's no need to create a slide deck\, but you'll be able to use the project
 or if you have a code sample or something else to share. While we'll ask 
 you if you'd like to participate when signing up\, this is just to gauge 
 interest\, and you can change your mind on the day of the event.\n\n20:00
 〜 21:00 Open Networking\n\nDiscuss the presentation\, how third time's 
 the charm\, or anything else Ruby related with the other attendees.\n\nDr
