I'm a Ruby developer from Helsinki, Finland. You can find me and my open source projects on GitHub as matiaskorhonen, I occasionally blog about programming and a variety of random things at randomerrata.com, and I tweet as @matiaskorhonen.
Oh no, it looks like Ruby has started ageing backwards and it's shedding language features version by version. First we'll lose pattern matching from Ruby 2.7 and it's only a matter of time before we lose the safe navigation operator from Ruby 2.3 and eventually even 1.9 style hashes will be gone. In this talk we take a Ruby script designed to run using the latest bells and whistles of Ruby 2.7 and port it to earlier versions of Ruby version by version. How far can we take this? Let's find out together!
Cast your mind back to the year 1995. Gansta’s Paradise is the top hit of the year. Friends is the hottest show on TV. And just days after I turn nine, Matz releases Ruby publicly for the first time. In this talk I go back to Ruby 0.95 and see what it takes to get it running on modern hardware.
I originally gave this talk at Rubyfuza 2017 and subsequently repeated it for the Ruby Dev Summit online conference.
The talk is about generic web security with a particular regard towards securing Rails applications.
Random Errata is my blog, where I occasionally write about tech stuff, beer making, and other random things.
