Various tips how to increase your productivity (esp. in Linux).

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

• Use Bash auto-completion (source /etc/bash_completion). Some tools have plugins, e.g. many Perl tools.
• export HISTCONTROL=ignoreboth results in bash history ignoring duplicate entries and entries starting with a space.

• bash-git-prompt shows e.g. the current branch and status. Martin Popel prefers to configure it (in bashrc) with

  export GIT_PS1_SHOWDIRTYSTATE=1
  export GIT_PS1_SHOWSTASHSTATE=1
  export PS1='[\t]\[\033[2;31m\]\h:\W\[\033[01;95m\]$(__git_ps1 "(%s)")\[\033[2;31m\]>\[\033[0m\] '

• tig text-mode gitk but better
• read https://guides.github.com/, understand GitHub flow, check GitHub training
• learn GitHub keyboard shortcuts, esp. “y” for permalink to a given line (line range) in source codes

• 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 and 6GB).
• See Python for using Python at ÚFAL.
• See 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
• Ondřej Bojar has implemented many Text utils, which he likes to use in his scripts and advises his students to do so as well.
