Happy Friday the 13th.

Busy hacking, so here's some topics to write about.

C++ hacks

• rcpp
• Flags
• kconf
• khmgr
• Build failure due to mismatched CXX/linker (TARGET vs TARGETS)

Adventures in writing a text editor

• Cursor bounds for windows
• Cursor math
• Scrolling
• Valid bounds for a doc (e.g. x >= 0, but -y means "scroll backwards in the previous line")
