An accredited Internet Astronaut from Finland.
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.
Talks
Ruby like it's 1995
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.
Rails Security: above and beyond the defaults
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.
