You can use [my keyboard layout optimizer](https://github.com/MTGandP/Typing) to create your own optimized keyboard. I provide a corpus of programming text you can use, and you can change the weightings to increase the significance of the programming text. (I don't remember if I wrote documentation explaining how to do this; if you want to do this but can't figure out how, remind me and I'll write up some documentation.)
