As soon as possible, I'd like to write something about:
* transforming a xml from a spreadsheet (''I'mworking m working on gnumeric'') to pdf by context;
* about python and context (cfr. ''TeX forever'' at preprint of EUROTEX 2005);
* context programming (cfr. ''Inside_ConTeXt'' in [http://sandbox.contextgarden.net/Inside_ConTeXt]); ''maybe I will start with core-ntb''
* Xy-pic (cfr. [http://tug.org/applications/Xy-pic/])
