Happy Pi Day! After almost two weeks since Mark came over to my house and inspired me to make the sunroom into my primary living/sleeping quarters, I moved back into the small upstairs room in anticipation of warmer summer temperatures in the months ahead. The savings on heating costs by maintaining only the sunroom at comfortable temperatures these past two weeks won't be seen until the first week of April, when I get my gas bill for this month.

A recent trip to the electric meter confirmed my suspicion that the solar panels are already generating more electricity than the house is using, even though we have yet to see the most rapid increase in hours of daylight as the vernal equinox approaches. In addition, the electric heater in the sunroom runs much quieter than the forced air in the rest of the house. Despite these considerations, the temptation to rearrange furniture yet again on a cloudy Friday afternoon proved irresistible, and I found myself sleeping last night in the small, dark room under several layers of comforters.

Today the forecasted rain finally blanketed the region, dissuading me from making the usual trip to Hyattsville for the game with the flying disc. Instead I stayed at home and tried to clean up the tags on my digital music collection, using the TUI application ncmpcpp. With full albums sorted into folders and properly tagged, a more versatile version of my wakeup alarm bash script can be implemented as follows.

PATH=/bin:/usr/bin;

mpc clear &>/dev/null           # unload the current playlist
mpc volume 100 &>/dev/null      # set the volume to 100%

case $# in
0 )
        mpc load wakeup &>/dev/null # load the playlist du jour
        mpc play &>/dev/null    # start the music!
        ;;

	
)

        list=$1 # first look for a list of that name ...
        if ! mpc load $list &>/dev/null ; then
                # ... no such list, look for a directory instead ...
                albumdir=`find /home/mpd/music -type d -name $list`;
                if [ -n $albumdir ]; then
                # ... remove prefix from the path before calling mpc add
                argtoadd=`echo $albumdir | sed 's,/home/mpd/music/,,g'`;
                mpc add $argtoadd &>/dev/null
                fi
        fi
        # make sure there's something to play before starting the music
        loaded=`mpc playlist`
        [ -n "$loaded" ] && mpc play $2 &>/dev/null
        ;;
