So I ordered some Tcl and Python books to replace the ones that seem to have disappeared in the process of moving. The first four have arrived already.

1.     Tcl/Tk Pocket Reference (two copies)
2.     Learn Python the Hard Way
... and two more.

I need to set aside a particular portion of the day. What tends to happen is other things spill over into the time I had set aside for learning. Then, because I can't keep a regular schedule, I don't wind up adding any knowledge. 

Also ... looking for more stuff on D-lang, Go-lang, Rust, Smalltalk (Squeak/Pharo, GNU Smalltalk, some of the JS-based web versions) and some human languages (Italian, Esperanto). Growth through learning.
