Building a MAME cabinet 8

I spent some more time on it this morning, after being too busy the last three weekends since I bought the plywood. Since I’m a power tool newbie, it’s going to take a while to complete. I learned a few things: My sawboard was too thick, since I made it from 3/4″ MDF. I had… Continue reading Building a MAME cabinet 8

Elbeno, now with 50% more everything

I just moved here from LiveJournal. All my LJ posts and comments have been migrated, thanks to some Perl & PHP wizardry. For now, this is the default WordPress theme.

Sgt Pepper Mashup

This is great. “Lucy at the River” is particularly inspired, I thought (also mirrored).

Thinking about ditching LJ

Arboreal Haskell

(Chapter 7 of The Haskell School of Expression is about trees.) The first definition is of a tree with values stored only at the leaves, i.e. data Tree a = Leaf a | Branch (Tree a) (Tree a) It then gives a mapTree function (equivalent to map on a list), which is trivial, and functions… Continue reading Arboreal Haskell
