For RubyTet today, I wrote the game control so that you can move around shapes. I still have not implement the shape changer though. Then I worked on adding rules for adding shapes since it isn't enough to be adding shapes to the field, but actually inserting in the correct position.
As for my other stuff...
Rails: I am momentary confused about rails migration. Tomorrow will clear up as I start over again over the migration part of the tutorial.
Trigonometry: I am proceeding slowly through chapter 3. Still many questions to go.
Libregamewiki: It is business as usual. Not much is going on there.
