I'm a mathematician working in algebra. I've been using TeX since 1987, but couldn't write my Ph.D. thesis with it. Sob!

I teach LaTeX at my university, besides the mathematics courses. I'm the author of some LaTeX packages and even of one Plain TeX package. At my site it's possible to download my book on LaTeX programming (in Italian, sorry).

Here's my motto for TeX.SX:

Pronto prontissimo son come il fulmine: sono il factotum della città. (From "Il barbiere di Siviglia", music by Gioachino Rossini, libretto by Cesare Sterbini.)

comment Is it possible to declare document to be math-free to stop “Missing $ inserted”?
Welcome to TeX.SX! If the document is math free, then \catcode`_=12 in the preamble will do, provided you also have \usepackage[T1]{fontenc}

comment Does polyglossia with LuaLaTeX hyphenate greek text?
The loaded hyphenation patterns are wrong, though: hyph-el-polyton.pat.txt instead of hyph-grc.pat.txt

comment TikZ/TeX: Minimum line width/maximum resolution
If I try tex "\vrule width 1pt height 1sp\bye" the DVI file will contain setrule height 1, width 65536 (this is what dvitype shows). If I change 1sp into 0sp, no setrule command is found (the rule acts like a space, as far as the DVI file is concerned). Then it's left to the printer driver to draw the rule, so it depends on the PDF specifications (and possibly on the printer driver) whether the rule will be visible or not.

This will have peculiar effects if \tableofcontents is used.

After further research it seems that the wrong language name is passed when language.dat.lua is examined.

comment Does polyglossia with LuaLaTeX hyphenate greek text?
If I do lualatex -recorder test, I find that LuaTeX loads hyph-el-polyton.pat.txt instead of the expected hyph-grc.pat.txt file.

@Aditya They are taken either from lasy10 (the old LaTeX font) or from the AMS symbol font (msam10).

comment Does polyglossia with LuaLaTeX hyphenate greek text?
No, it apparently doesn't. I see no difference between the output with XeLaTeX and LuaLaTeX, apart from the missing hyphenation. Support for ancient Greek hyphenation has recently changed, so I guess it's a problem with the incomplete port of polyglossia to LuaLaTeX or, possibly, with the hyphenation pattern loading in LuaLaTeX.

Should the integer be the largest integer less than or equal to the quotient?
