LaTeX ===== It was a nice surprise that some conferences still use LaTeX templates which do not require a latest XeTeX, LuaTeX and use of 6 GHz processors in order to process the document. I'm preparing paper for this one [1] and it's nice to use my O2 with 10 (or so) years old installation of the TeXLive [2] without any issues. Well, it's stupid that you have a system that is backward compatible (the TeX) but for actual work you have use a front-end that is not compatible in any direction (LaTeX...).
