2. Conky Launcher 

I have the following set to launch after loading of KDE. 

#!/bin/bash

# start conky
conky -&
sleep 3
# set the correct background for desktop integration
feh --bg-scale /home/gvandeweyer/Pictures/zim_gray.png 

3. Spotify information

Adapted from snippets around the web. My main contribution was to include correct timing when spotify is paused.

conky.spotify.nowplaying.work.sh:

#!/bin/bash
# Spotify Conky Now Playing
# adapted from the script by Paul Williams 
if [ ! -f ~/.cache/spotify-nowplaying ]
	then
		~/bin/conky.spotify.nowplaying.sh > ~/.cache/spotify-nowplaying
fi
if [ ! -f ~/.cache/spotify-paused ]
	then
		echo "0" > ~/.cache/spotify-paused
fi

# Is the same song playing?
if [ "$(~/bin/conky.spotify.nowplaying.sh)" != "$(cat ~/.cache/spotify-nowplaying)" ]
	then
		~/bin/conky.spotify.nowplaying.sh > ~/.cache/spotify-nowplaying
		~/bin/conky.spotify.nowplaying.length.sh > ~/.cache/spotify-nowplaying-length
		length=$(cat ~/.cache/spotify-nowplaying-length)
		secs=$(($length/1000000))
		printf ""%d:%02d"\n" $(($secs%3600/60)) $(($secs%60)) > ~/.cache/spotify-nowplaying-length-pretty
		date +%s > ~/.cache/spotify-nowplaying-starttime
		# reset paused time.
		echo "0" > ~/.cache/spotify-paused
fi
## is it playing, or paused?
status=$(qdbus org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.freedesktop.DBus.Properties.Get org.mpris.MediaPlayer2.Player PlaybackStatus)
if [ "$status" == "Paused" ]
	then
		pt=$(cat ~/.cache/spotify-paused)
		pt=$(($pt+1))
		echo "$pt" > ~/.cache/spotify-paused
#else
	#echo "0" > ~/.cache/spotify-paused
fi
pt=$(cat ~/.cache/spotify-paused)

# Work out time elapsed as a percentage of the total time.
timethen=$(cat ~/.cache/spotify-nowplaying-starttime)
timenow=$(date +%s)
# +1 to combat slight delay
elapsed=$((($timenow+1)-$timethen-$pt))
printf ""%d:%02d"\n" $(($elapsed%3600/60)) $(($elapsed%60)) > ~/.cache/spotify-nowplaying-elapsed-pretty
# Got the elapsed time, now percentage!
#totallength=$(cat ~/.cache/spotify-nowplaying-length)
#totallengthsecs=$(($totallength / 1000000))
#elapsedper="$elapsed / $totallengthsecs"
#elapsedperc=$(echo "scale=2; $elapsedper" | bc ;)
#elapsedperce="$elapsedper * 100"
#elapsedpercent=$(echo "scale=2; $elapsedperce" | bc ;)
#echo $elapsedpercent > ~/.cache/spotify-nowplaying-elapsed
chmod 777 ~/.cache/spotify-*

 conky.spotify.nowplaying.sh : 

#!/bin/bash

echo "  Artist:" `dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.freedesktop.DBus.Properties.Get string:'org.mpris.MediaPlayer2.Player' string:'Metadata'|egrep -A 2 "artist"|egrep -v "artist"|egrep -v "array"|cut -b 27-|cut -d '"' -f 1|egrep -v ^$`

conky.spotify.nowplaying.length.sh : 

#!/bin/bash

echo `dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.freedesktop.DBus.Properties.Get string:'org.mpris.MediaPlayer2.Player' string:'Metadata'|egrep -A 2 "length"|egrep -v "length"|egrep -v "array"|cut -b 43-|cut -d '"' -f 1|egrep -v ^$`

4. Todo.txt

Plain integration from the todo.txt package with regard to configuration and colors. I wrote a small subscript to split up my todo's between work and non-work tasks, and to limit the number shown. 

~/.todo/config-conky: 

# todo.txt configuration for Conky highlighting. 
export ORANGE='${color orange}'
export BLACK='${color black}'
export RED='${color D90000}'
export GREEN='${color green}'
export BROWN='${color brown}'
export BLUE='${color blue}'
export PURPLE='${color purple}'
export CYAN='${color cyan}'
export LIGHT_GREY='${color LightGrey}'
export DARK_GREY='${color DarkGrey}'
export LIGHT_RED='${color LightRed}'
export LIGHT_GREEN='${color LightGreen}'
export YELLOW='${color yellow}'
export LIGHT_BLUE='${color LightBlue}'
export LIGHT_PURPLE='${color LightPurple}'
export LIGHT_CYAN='${color LightCyan}'
export WHITE='${color white}'
export DEFAULT='${color black}'
source ~/.todo/config # Adapt this to wherever your todo.txt configuration is located.

conky.todo.pl: 

#!/usr/bin/perl
my $limit = 6;  # shows 5 + N-more line.
print '${font Bitstream Vera Sans Mono:size=9:italic}${color D90000}Todo Work$font ${color DimGray}${hr 2}'."\n";
my @work = split(/\n/,`todo.sh -d ~/.todo/config-conky ls work | grep -v -P '^--\$|^TODO:\\s'`);
my $idx = 0;
while ($idx < $limit - 1) {
	if ($idx == scalar(@work)){
		last;
	}
	my $line = $work[$idx];
	while ($line =~ m/\+\w+/) {
		$line =~ s/\+\w+//;
	}
	$line =~ s/\s+/ /g;
	print "$line\n";
	$idx++
}
## 
if (scalar(@work) > $limit) {
	my $diff = scalar(@work) - $limit - 1;
	print "   .. $diff more on full list\n";
}
elsif (scalar(@work) == $limit) {
	my $line = $work[$limit-1];
	while ($line =~ m/\+\w+/) {
		$line =~ s/\+\w+//g;
	}
	$line =~ s/\s+/ /g;
	print "$line\n"; 	
}
print '${font Bitstream Vera Sans Mono:size=9:italic}${color D90000}Todo Other$font ${color DimGray}${hr 2}'."\n";
my @work = split(/\n/,`todo.sh -d ~/.todo/config-conky ls | grep -v '+work' | grep -v -P '^--\$|^TODO:\\s'`);
my $idx = 0;
while ($idx < $limit - 1) {
	if ($idx == scalar(@work)){
		last;
	}
	my $line = $work[$idx];
	while ($line =~ m/\+\w+/) {
		$line =~ s/\+\w+//g;
	}

	print "$line\n";
	$idx++
}
## 
if (scalar(@work) > $limit) {
	my $diff = scalar(@work) - $limit - 1;
	print "   .. $diff more on full list\n";
}
elsif (scalar(@work) == $limit) {
	my $line = $work[$limit-1];
	while ($line =~ m/\+\w+/) {
		$line =~ s/\+\w+//g;
	}

	print $line; 	
}

5. Monitor for a torque server

the script to run on a webserver with access to the queue:

<?php
$running = `qstat -r | wc -l`;
$running = $running - 5;
$queued = `qstat -i | wc -l`;
$queued = $queued - 5;
if ($running + $queued < 10) {
        $all = `qstat -a | tail -n+3 | grep -vP '\sC\s'`;
}
else {
        $all = `qstat -a | tail -n+3 | grep -vP '\sC\s' | head -n 9`;
        $all .= "...".($running+$queued)." in total...\n";
}
if ($queued < 0) {
        $queued = 0;
}
if ($running < 0) {
        $running = 0;
}

echo "Running: $running\n";
echo "Queued : $queued\n";
$lines = explode("\n",$all);
array_shift($lines);
$lines[0] = str_replace('Job ID', 'JobID',$lines[0]);
$idx = 0;
foreach ($lines as $key => $line) {
                if ($line == "") {
                        $idx++;
                        continue;
                }
                $cols = preg_split("/\s+/",$line);
                if ($idx == 1) {
                        echo $cols[3]."  ".$cols[6]."\t".$cols[7]."\t"."$cols[9]"."  ".$cols[10]."\n";
                }
                else {
                        if (strlen($cols[3]) < 16) {
                                echo $cols[3]."\t   ".$cols[6]."\t".$cols[7]."\t"."$cols[9]"."  ".$cols[10]."\n";
                        }
                        else {
                                echo $cols[3]."  ".$cols[6]."\t".$cols[7]."\t"."$cols[9]"."  ".$cols[10]."\n";
                        }
                }
                $idx++;
}


?>

And a script to monitor the status. This is run from the autostart of kde in my case. 

#!/bin/bash
echo "Starting up..." > ~/.conky_clusterstat.txt
echo "." >> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt
echo ".">> ~/.conky_clusterstat.txt

sleep 60 
while [[ 1 ]] ; do 
	curl http://server-url/cluster_stats.php > ~/.conky_clusterstat.txt
	sleep 60;
done

6. Mandatory Screenshot

Cluster, Conky, mpd, spotify, todo.txt, torque/pbs
