One time I fixed an LCD monitor with a folded piece of paper

Some of the colors weren't working on the Monitor. I found pressing around the plastic border of the screen brought them back. I opened the monitor casing and used the folded paper to put pressure against the LCD panel and housing. Wah Lah. More of a bend than a hack I guess.

NAME

       git-var - Show a Git logical variable

SYNOPSIS

       git var ( -l | <variable> )

DESCRIPTION

       Prints a Git logical variable.

OPTIONS

       -l
           Cause the logical variables to be listed. In addition, all the variables of the Git configuration file .git/config are listed as well.
           (However, the configuration variables listing functionality is deprecated in favor of git config -l.)

EXAMPLE

           $ git var GIT_AUTHOR_IDENT
           Eric W. Biederman <ebiederm@lnxi.com> 1121223278 -0600

VARIABLES

       GIT_AUTHOR_IDENT
           The author of a piece of code.

           The person who put a piece of code into Git.

       GIT_EDITOR
           Text editor for use by Git commands. The value is meant to be interpreted by the shell when it is used. Examples: ~/bin/vi,
           $SOME_ENVIRONMENT_VARIABLE, "C:Program FilesVimgvim.exe" --nofork. The order of preference is the $GIT_EDITOR environment variable,
           then core.editor configuration, then $VISUAL, then $EDITOR, and then the default chosen at compile time, which is usually vi.

       GIT_PAGER
           Text viewer for use by Git commands (e.g., less). The value is meant to be interpreted by the shell. The order of preference is the
           $GIT_PAGER environment variable, then core.pager configuration, then $PAGER, and then the default chosen at compile time (usually
           less).
