+  * Ondřej Bojar prefers to store the history in each directory in ''.history-bojar''. See ''/home/bojar/diplomka/granty/cracker-2015/mtm-2016-organization/accounts-mtm16/bash-profile-for-ufal-accounts''
+    * Note that this creates the ".history-your-name" wherever you have write access and some ÚFALers are not happy with this. In addition everyone sees what you did (this may be useful, but be careful).

   * See [[Python]] for using **Python** at ÚFAL.

   * 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.

   * Ondřej Bojar has implemented many [[http://www1.cuni.cz/~obo/textutils/|Text utils]], which he likes to use in his scripts and advises his students to do so as well.

+  * [[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).
