Today I was randomly selected for a lightning talk (3 mins) at Tokyu Ruby Kaigi and made up the contents on the spot today but it went okay I think😂 #tqrk15

I’ve just set up an iPad OS device from an existing one and the migration somehow screwed up my VPN settings on the new one. It was able to ping IP addresses but no DNS or traceroute. It took me2 days to realise I needed to delete the VPN settings 🫠

Today I had my first Japanese style annual health exam… The x-ray photos with barium sulfate was… an interesting new experience. Do people do this every year?

Just done early voting for the Tokyo Governor election. I wish there was at least one candidate I could really support, rather than trying to pick the least harmful one…

It’s so heartening to see that no matter what language or platform everyone debugs by calling the equivalent of printf everywhere 🥹 #TokyoRubyistMeetup

Tonight I presented my cross platform mruby on Wii and Dreamcast at Tokyo Rubyist Meetup. My Dreamcast and Wii both worked well and I received lots of good feedback 😄

The legend who brought us mRuby for the Sega #Dreamcast has now also brought it to the Wii and is proving that it can do a damn fine job at being a high-performance scripting language for gamedev and embedded systems! #gamedev #retrogaming

I presented my cross-platform mruby on Dreamcast and Wii at #rubykaigi2024 today! I think the reaction was generally positive 😆

I worked on presentation app on Sega Mega Drive this weekend and I think I fixed a memory issue that was bugging me for a while. Feels good to have fixed it!
