| | * [[http://mg.readthedocs.io/latexmk.html|latexmk]] can be used with ''-pdf -pvc'', so whenever you save a ''tex'' file, the corresponding ''pdf'' will be regenerated (and your pdf viewer will refresh). Other useful options are ''-interaction=nonstopmode -synctex=1'', see e.g. [[https://tex.stackexchange.com/questions/118489/what-exactly-is-synctex|synctex]] |
| | * [[https://www.pdflabs.com/docs/pdftk-cli-examples/|pdftk]] for merging and splitting pdf files (and much more) from the command line |
| | * use [[https://tex.stackexchange.com/questions/23104/using-and-interpreting-pdffonts|pdffonts]] to check if all fonts in your pdf are //embedded// (only the used subset). |
| | * <code>gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=CompressedWithEmbeddedFonts.pdf Original.pdf</code> |
| | * http://ufal.mff.cuni.cz/~popel/latex.pdf other hints (mostly for newbies) in Czech |

| * You **should not turn off** Linux workstations at ÚFAL, unless really needed (or agreed with it@ufal). In that case, try the standard ways, and if they do not work, try Ctrl+Alt+SysRq+[R,E,I,S,U,B] rather than plug out power cable.
