-  * When using **Perl** at ÚFAL, we recommend using [[Perlbrew]] with shared perl interpreters (different versions) and shared Perl modules (which otherwise take several hours to install). +===== Editors ===== 
-  * See [[Python]] for using **Python** at ÚFAL. +Who uses which editor and is willing to provide a mini-training for new users (show config, favorite macros, highlighters etc.). 
 +Feel free to add your name and editor. 
 + 
 +  * **vim**: Ondřej Bojar, Ruda Rosa, Milan Straka (C++ completion, Python completion, asynchronous make), ... 
 +  * **emacs**: ? 
 +  * **atom**: Martin Popel 
 + 
 +===== Bash ===== 
 +  * Use Bash auto-completion (''source /etc/bash_completion''). Some tools have plugins, e.g. many [[https://metacpan.org/pod/Bash::Completion|Perl tools]]. 
 +  * ''export HISTCONTROL=ignoreboth'' results in bash history ignoring duplicate entries and entries starting with a space. 
 +  * See ''/ha/home/bojar/diplomka/granty/cracker-2015/mtm-2016-organization/accounts-mtm16/bash-profile-for-ufal-accounts'' for: 
 +    * bash history local in the current directory 
 +===== Git ===== 
 +  * [[https://github.com/magicmonty/bash-git-prompt|bash-git-prompt]] shows e.g. the current branch and status. Martin Popel prefers to configure it (in bashrc) with

 +  * read https://guides.github.com/, understand [[https://guides.github.com/introduction/flow/|GitHub flow]], check [[https://services.github.com/on-demand/resources/learning-path/|GitHub training]] 
 +  * learn [[https://help.github.com/articles/using-keyboard-shortcuts/|GitHub keyboard shortcuts]], esp. "y" for permalink to a given line (line range) in source codes

 +  * See [[internal:remote access]], esp. for byobu and mosh.
   * 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. Mnemonics: "Reboot Even If System Utterly Broken", see http://en.wikipedia.org/wiki/Magic_SysRq_key#Uses   * You **should not turn off** Linux workstations at ÚFAL, unless really needed (or agreed with it@ufal).

 +  * 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.
 +    * The web versions of the text utils are often older than the ones in ''/home/bojar/tools/vimtext'' and ''/home/bojar/tools/shell''
