Status update

Some days off, not very much done. Somehow relevant in the context of this stream:

• Writing some simple Common Lisp, for exercise. The Wireworld simulator and editor –which has some significance per se besides being interesting as a CL exercise– is on pause (while I try to figure out Lispbuilder-sdl's ways of treating surfaces), and I'm now on something simpler. It's a Sudoku solver assistant. It's not clear to me what the scope of the project will be, however I'm discovering handy techniques and tools useful for a "real" system: for example I borrowed from scmutils the idea of using TeX to obtain a representation of the Sudoku problem (it's faster than I initially thought).
• Reading Seveneves by Neal Stephenson. I hope to write something more substantial as I reach its end.
