Unmaned harpoon

That’s what Rosetta will fire at poor ol’ Churyumov–Gerasimenko in November, any other Duck might be scared. Remember all the technology has been launched Years before the first Smartphone. Mankind has come quite a long way.

Rosetta's harpoon

On Max-Planck-Institut für extraterrestrische Physik is a very detailed (german) Presentation.

Further Informations from the Manufacturer: Faulhaber

See it in action : Scientists Test Harpoon Used in Rosetta Probe

The font (if I might call it so) was truthfully copied from my trusty HP32s.

The svgs are outlined so a cutter should be able to parse it.

Normaly a show access-list would bring up something like

access-list OUTSIDE-IN line 1 extended permit ip object-group FOO any (hitcnt=9001)
  access-list OUTSIDE-IN line 1 extended permit ip host 10.42.23.1 any (hitcnt=9000)
  access-list OUTSIDE-IN line 1 extended permit ip host 10.42.23.2 any (hitcnt=1)
  access-list OUTSIDE-IN line 1 extended permit ip host 10.42.23.3 any (hitcnt=0)
  access-list OUTSIDE-IN line 1 extended permit ip host 10.42.23.4 any (hitcnt=0)
  access-list OUTSIDE-IN line 1 extended permit ip host 10.42.23.5 any (hitcnt=0)
  access-list OUTSIDE-IN line 1 extended permit ip host 10.42.23.6 any (hitcnt=0)
  access-list OUTSIDE-IN line 1 extended permit ip host 10.42.23.7 any (hitcnt=0)
access-list OUTSIDE-IN line 2 extended permit ip object-group BAR any (hitcnt=9002)
  ...

Sometimes you just like to see the leading configuration lines. To get there you can simply exclude a double whitespace like:

show access-list | exclude \ \ 
access-list OUTSIDE-IN line 1 extended permit ip object-group FOO any (hitcnt=9001)
access-list OUTSIDE-IN line 2 extended permit ip object-group BAR any (hitcnt=9002)
bash

bash-completion for arbitrary commands

To use the completion for ssh for any command ssh * /etc/bash_completion:

. /usr/share/bash-completion/bash_completion
# set up dynamic completion loading
_completion_loader()
{
  local compdir=./completions
  [[ $BASH_SOURCE == */* ]] && compdir="${BASH_SOURCE%/*}/completions"
  # Try basename.
  . "$compdir/${1##*/}" &>/dev/null && return 124
  # Arbitrary ssh command
  [[ $1 =~ .*ssh ]] && . /usr/share/bash-completion/completions/ssh >/dev/null 2>&1 && complete -F _ssh $1 && return 124

    # Need to define *something*, otherwise there will be no completion at all.
  complete -F _minimal "$1" && return 124
} &&
complete -D -F _completion_loader

Note: completion loader was mostly extracted from /usr/share/bash-completion/bashcompletion itself, just the “# Arbitrary ssh command” part was added.
