Recap

• internet:
  • connect to the local wifi ("LAUNCH/CO");
  • start your browser.. and wait.. for the login page..
  • enter the user+pass for this event (see whiteboard)
• projector:
  • it didnt recognize the laptops with VGA. :-(
  • bring a VGA extension cable next time.
  • the HDMI failed once in a while.. loose connection? overheating?
• room:
  • we had been seven persons. there was maybe room for one more person.
  • then it gets awkward. definitely not enough space for 20 people.
• drinks: club-mate for 1,00€ :)

Sven Guckes

• almost never uses the mouse
• current window manager: "i3" (small+fast!)
• has been using screen as an environment for 20+ years
• maintainer of the screen maillist gnu-screen 2000-2004 https://groups.yahoo.com/neo/groups/gnu-screen/info
  • http://www.guckes.net/Screen webpages on screen
• setup files:
  • http://www.guckes.net/Setup/screenrc.minimal 450byte
  • http://www.guckes.net/Setup/screenrc (58KB): includes many examples, links about screen, a description of copy mode, and some general problems on screen
• screen or tmux? tmux!
  • comparison: http://www.guckes.net/tmux/vs.screen.txt

screen: some remarks:

• screen+tmux: keep programs running
• terminology:
  • screen: windows with regions
  • tmux: windows with panes
• splitting: horizontal und vertikal
  • screen: global layout
  • tmux: each window can have different panes
• useful shell aliases:

alias   \\?='screen -ls'
alias   \\!='screen -r'
alias    x='screen -x'

• screen: starting sessions with config files

screen -c $file
alias WORK='screen           -m -c ~/.screenrc.work'
alias COMM='screen -t COMM 9 -m -c ~/.screenrc.comm'
-> ":source" allows splitting of config files
  (shells, mutt and vim allows this, too=

• bindings: allows to start programs and webpages easily (zB htop, imdb, mtr, mutt,vim; web: dict,google,imdbhj)

other tools:

• irssi: "a modular IRC client for UNIX" backlog completion - ading tab completion for prefix of words which had been used in conversation (private or in public, ie on channels)
• http://www.guckes.net/irssi/scripts/backlog_completion.txt written by Florian Ragwitz
• xsel: "manipulate the X selection" http://www.vergenet.net/~conrad/software/xsel/ copies text from shell/vim from/into the X clipboard -> no need for vim to be compiled with clipboard support
  • same functionality for MacOSX: pbcopy + pbpaste http://osxdaily.com/2007/03/05/manipulating-the-clipboard-from-the-command-line/
• zsh: fc - "The fc command controls the interactive history mechanism." builtin command to edit last command

Questions

• screen: backlog search with patterns? -> tmux+copycat!
• tmux: does it have a zombie mode?
• vim: tab management. "jump to tab with 'foo' in its name" - possible?
• vim: how do you handle empty/new buffers?
  • eg "list all buffers without a file"

Ideas

Christian: - tmux: allow naming of panes/windows with letters (instead of numbers)

Sven: - CryoPID: "A Process Freezer for Linux" https://code.google.com/p/cryopid/ - CryoPID can move your running Linux programs from one computer to another. has anyone used this yet? - reptyr: "Tool for moving running programs between ptys" - feh: "image viewer and cataloguer"

bilder sortieren per key bindings -> actions
parameter: --action1 .. --action9
action1:    save pictures to subdir1 (good -> keep)
action2:    save pictures to subdir2 (bad  -> keep for now)
action3:    save pictures to subdir3 (ugly -> to be deleted)

• screen: use case embedded device -> Bjoern Buerger
• mutt+vim: colouring/farben
• tmux: use extra pane to show key input (four/five lines)
• vim: running several instances on the same files (swapfile issues)
• vim: compare nerdtree to Explore to vimnegar(?)

Thanks to Sven Guckes for writing the notes.
