- Determine which of the USR signals sent by e.g. kill(1) are available for customization of this sort
- Define signal handlers for raspivid that set the input framerate NOTE: it is preferred that the video stream not have to be reset when the frame rate is set while raspivid is running
- Sequence:
- capture frame
- run initial frame analysis on first frame
- save results
- increment frame rate
- loop

screen, tset, & emacs
Have had an issue w/ using emacs and screen together under Bash on a CentOS Linux host.
Problem
The problem manifests in two ways:
-
font-lock-modedoes not show in color, or in a limited subset of colors - the
Backspacekey sends^HbutEmacsrecognizes it as the "Help" invocation, and starts up the Help system
These problems have been showing up under screen but not when Emacs is started outside screen in the normal Bash shell.
Changing the TERM value and/or the Backspace in either or both of the terminal emulator software (PuTTY) did not fix the problem.
Setting the value of the TERM environment value in Bash had no apparent effect.
The Fix
Use tset to set the backspace character in the Bash shell before screen is started.
tset -e ^H
This works when TERM=vt102 in the Bash environment, and 'VT100+' is checked for the terminal type in PuTTY. Other term types may vary.
Note that for some reason the font-lock-mode problem went away, too.

Favorite Emacs Customizations
Somebody asked me the other day what Emacs customizations use. My response was that I don't use many customizations in Emacs because it would require me to carry those customizations around with me. However, I thought I would make a list, since this will be useful in the future when I am - again - using a vanilla Emacs install and want to make all the customizations at once, at startup.
Option Configuration
column-number-mode: HIDE scroll-bar-mode:OFF tool-bar-mode:OFF auto-fill-mode:ON transient-mark-mode:ON global-font-lock-mode:ON
Major Modes
sgml-mode html-mode php-mode js-mode css-mode
sgml / html modes are commonly installed by default, now, and I've seen a couple installs where php-mode and one or more of javascript-mode (or js-mode) and css-mode were also installed "out-of-the-box"
These modes are all defined by Elisp (.el) library files (usually compiled to .elc files). Once the library files are installed (e.g. in /usr/lib/perl/<ver>/site/ or /usr/share/emacs/site or whereever), they can be loaded using M-x 'load-library' command.
These libraries can also be loaded from your .emacs file and made to use a 'hook' function that auto-loads the appropriate mode based on the file extension cue for the source language of the file.

Bash code: CVS status logging
This command has the effect of checking each of the indicated files in the source tree against the CVS repository - errors should be propagated to stderr if a file in the source tree does not exist in the CVS repository - this cmd should be refined into a script which tests for error on status and tries to add source files which do not appear to be in the repository....
for fn in *.{css,js,html,php} ./xml/*.xml ./xml/services/*.xml ./js/*.js ;
do echo $fn ;
cvs status $fn;
echo ""; done > cvs-status.txt
Note that the command cvs status [in src dir, w/ no args] does something similar to the above command, differing in that using cvs status may not handle the cases a source file exists which has not been added to the repository.
The CVS manpage does not address this:
status [-lRqQ] [-v] [files...]
Requires: working directory, repository.
Changes: nothing.
Display a brief report on the current status of files with
respect to the source repository, including any ``sticky'' tags,
dates, or -k options. (``Sticky'' options will restrict how
`cvs update' operates until you reset them; see the description
of `cvs update -A...'.)
You can also use this command to anticipate the potential impact
of a `cvs update' on your working source directory. If you do
not specify any files explicitly, reports are shown for all
files that cvs has placed in your working directory. You can
limit the scope of this search to the current directory itself
(not its subdirectories) with the standard -l option flag; or
you can explicitly request recursive status reports with the -R
option.
The -v option causes the symbolic tags for the RCS file to be
displayed as well.
