Actually this should've been really easy. A small script loop on the kindle to log the battery consumption and then plug that data into gnuplot. But it turned out gnuplot afaik doesn't support to output the difference between values. Thanks to apo_ from #gnuplot I've got it running with the help of awk now. The great thing is that this script runs in busybox and can hence easily be adapted for pretty much any kind of portable devices including Android phones, Kindles, Tablets, Notebooks, Netbooks, etc. And that's how it looks.

I wrote this for my kindle and android devices. It's a nice, easy script though and should be great especially for embedded environments, where you have a shell but not all of the powertop dependencies. It works wonderfully on my notebook and netbook, but you may have to slightly adjust the path names to work on your system.
It turns out that this wasn't needed for either, as the kindle comes with powertop preinstalled. But it can't work on either of my devices, as timer_stats are disabled in their kernels.
I do wonder: Why do they disable the timer_stats? Is the overhead of timer_stats too high? Let me know how you use it!

With the realease off ffmpeg 0.5 there is much better AVCHD support in my experience, so you can use it for perfect conversions. You can download ffmpeg from ffmpeg.org and then use this script:
#!/bin/sh
# ffmpeg-avchd script by linux-tipps.blogspot.com# to encode a directory use this command:
# for i in *.m2ts; do ffmpeg-avchd $i; done
IN="$1"; shift
OUT=$(echo $IN | sed 's/.m2ts//')-720p.avi
echo Encoding $IN to $OUT.
ff="ffmpeg -deinterlace -i "$IN" -acodec copy -vcodec libx264 -vpre normal -crf 25 -sws_flags lanczos -s hd720 -r 25"
echo $ff $OUT
nice $ff "$OUT"
The only thing I'm not really happy with yet is the deinterlacing and deshaking. I would like to use a sharper deinterlacer, but I guess I'd need mencoder for that. The Lanczos software scaler does make steady images pretty sharp already, though.

Okay, I may not be able to completely fulfill that promise, but you will most likely be saved from the second pass and thus a lot of encoding time quite often with this tip. If you don't need the resulting file to e.g. fit on a CD, Constant Ratefactor aka Constant Quality is probably perfect for you. Let me supply you with a quick overview and my quick mencoder script that does the job.
Did you know you can use a roughly vorbis-like quality selection, constant quality
crf even in x264? This will save you a lot of encoding time with
more or less the same quality. Or
maybe not? Well it will look different, but it
should be fine. For x264 a range of 18-26 is
recommended. The higher the number the lower the bitrate and thus the file size will be.
Nice! Finally I don't need to adjust and calculate bitrates myself anymore! The algorithms really seem to work, because when I now change the codec settings to more efficient ones (e.g. increase the frameref, subq or enable mixed_refs) the quality (SSIM) remained pretty similar, while the bitrate sank.
Some experience with the parameters: The mixed_refs parameter did regularly increase the SSIM for me, but also took a lot more time to encode. Frameref=2 increases the efficiency with little performance impact in my experience. I wonder why it's not the default. Bframes decrease the quality slightly but shave a lot off the bitrate and even increase performance a bit for me.
Let me show you my "quick" example script for mencoder.
#!/bin/bash
CRF=23.5 # 21-26 recommended, the higher the smaller the resulting file, see http://mewiki.project357.com/wiki/X264_Settings#crf
INPUT="$1"; shift
X264OPTS="$1"; shift
OUT=`basename "$INPUT"`"-x264.avi"
echo Encoding $INPUT to $OUT
mencoder="time nice /usr/bin/mencoder -quiet -cache 16384"
enc="$mencoder -ovc x264 -oac copy -x264encopts crf=$CRF:trellis=1:frameref=2:bframes=2:8x8dct:psnr:ssim:$X264OPTS"
# I suggest nr= of no more than 2 or 3 with current x264 from svn.
# something along the lines of -vf
# eq=contrast=20:brightness=2,hue=saturation=1.25 for bleak videos
# denoise3d for noisy and unsharp=l:3x3:1.045 for blurry videos.
# I recommend to try out the result with mplayer first.
# A combination of all may work well, too.
echo $enc -o "$OUT" "$INPUT" $*
[ -f "$OUT" ] && echo File exists && exit 1;
$enc -o "$OUT" "$INPUT" $*
# You can call the script like this:
# script.sh input [x264encopts] [mencoder parameters]
# $ sh menc.sh somefile.mpg "interlaced" "-vf crop=..." or
# $ sh menc.sh somefile.mpg "" "-vf crop=..." or simply
# $ sh menc.sh somefile.mpg
# to get the right crop settings try $ mplayer -vf cropdetect
Feel free to get out the flame thrower - or just make some productive comments.

If you're installing a few programs in WINE, you may notice that they tend to influence each other negatively. The fix is to install them in completely different operating system environments, also known as WINE bottles. This way it's easy to completely remove applications by just deleting their "bottle". Let me show you how to make this effortless with standard WINE and a simple shell script.
The script is the key part. You tell it a directory where you want your bottles installed and then it will create a new folder each time you install a program. Of course you may also install several programs into one bottle. Let's call the script wine-bottle, which I suggest to put into your $PATH:
!/bin/bash
# wine-bottle v. 0.2
# (c) 2009 Linux-Tipps.blogspot.com, (c) 2009 Joost @ http://home.student.utwente.nl/j.vanderhof
# newest version at http://linux-tipps.blogspot.com/2009/03/how-to-make-your-own-wine-bottles.html
# published under the GPL v. 3.0 http://gplv3.fsf.org/
INSTALLDIR="$HOME/.wine/bottles"; #Set this to where you want to put your Wine bottles
[ $# -lt 1 ] && #if you gave no parameters
echo "Please give me parameters! Usage:" &&
echo "Execute a program : $0 \"BottleName\" \"Program\"" &&
echo "Configure a bottle : $0 --conf \"BottleName\"" &&
echo "List bottles : $0 --list" &&
exit 1;
[ $# -lt 2 -a $1 != "--list" ] && #if you didn't give the right parameters
echo "Please give me at least two parameters or a --list parameter! Usage:" &&
echo "Execute a program : $0 \"BottleName\" \"Program\"" &&
echo "Configure a bottle : $0 --conf \"BottleName\"" &&
echo "List bottles : $0 --list" &&
exit 1;
[ $1 == "--list" ] && #if you want to list the bottles
echo "Wine bottles in $INSTALLDIR:" &&
ls -1 $INSTALLDIR &&
exit 1;
[ -d "$INSTALLDIR" ] || ( #if installdir is not existing
echo "Root of Wine bottles not existing: $INSTALLDIR" &&
mkdir "$INSTALLDIR"
) || ( #if installdir creation failed
echo "Could not create installation Directory: \"$INSTALLDIR\"." &&
exit 1);
which wine || ( #if wine is not found
echo "Wine not found, please install it first" &&
exit 1);
[ $1 == "--conf" ] && #if you wish to configure a bottle
WINEPREFIX="$INSTALLDIR/$2/" winecfg &&
exit 1;
#finally, the only remaining possibility is you want to run an application
PREF="$1";
shift; #drop first parameter to leave the command with its parameters
WINEPREFIX="$INSTALLDIR/$PREF/" wine "${@}";
You can now use this script almost like wine. The only difference is that you first need to tell it the bottle's name. E.g. wine-bottle lingopad setup.exe installs the program inside setup.exe into the bottle lingopad. I suggest using the "create Desktop short cut" option of installers, as it lets you easily start them later, without the need to use this script.
If you want to create a backup of your bottle, simpy put the bottle directory inside $INSTALLDIR together with the related .desktop file into an archive. If you want to manually start a program, you can of course still use wine-bottle from the shell: e.g. wine-bottle lingopad "$HOME/Wine/lingopad/drive_c/Program Files/Lingopad/Lingopad.exe".
You may also want to install a current wine via the
wine ubuntu repository.
Let me know if you liked this howto!
Update: Updated to Joost's version, thanks!
Update2: It seems my script has inspired "Joost". He's created a version including a simple GUI. Check out his
website.

I bought a notebook to be flexible, but when at home I use it with external monitor, keyboard and mouse to be comfortable. Now the problem was that I couldn't tell Ubuntu I want to only use the external monitor - if it's available.
Well, I've written a one-liner that fixes that problem. If the external display is attached, it will automatically switch over to it and display the internal display. Otherwise it boots normally (leaving the internal display enabled).
I put the script into the Xsession.d directory so it gets started for every user on boot:
/etc/X11/Xsession.d/98vgaonly and made it executable.
The actual script line is this:
xrandr -q | grep 'VGA connected' && xrandr --output LVDS --off --output VGA --autoIt checks if the line 'VGA connected' was found in xrandr's query and then asks your X server to turn off the internal output and use the external one with automatic resolution detection.
So to automatically switch to a connected VGA during boot just execute:
echo 'xrandr -q | grep \'VGA connected\' && xrandr --output LVDS --off --output VGA --auto' | sudo tee /etc/X11/Xsession.d/98vgaonly && sudo chmod a+x /etc/X11/Xsession.d/98vgaonly
You may have to change the name of the outputs for your setup. xrandr -q will let you know what's available. It would probably be possible to somehow call this script automatically when plugging in a monitor, but I've not figured out how. xrandr only works when called from inside the running X session in my experience.
If you want to know
more about XRandR, check this recent article.
Any comments are welcome!

This script lets you easily mirror a local directory to foreign computers that have rsync installed - securely via ssh. It assumes you have already set up a public key authentication with those servers. (Have a look at ssh-keygen and ssh-copy-id)
#!/bin/sh
# (c) 2008 linux-tipps.blogspot.com
#
FROM=/home/user
# the base path
DIRS="Desktop Documents"
# you can also use absolute paths
RSYNC="rsync -av --progress -e ssh"
# add -z for compression
ssh-add -l || ssh-add
# this adds ssh private keys if not added already
# for cron scripts use keychain instead:
# source ~/.keychain/*-sh
# see here for more
cd $FROM
$RSYNC -z $DIRS djtm@server1:/some/path/Backup/ &
$RSYNC $DIRS djtm@server2:/some/path/Backup/ &
wait && echo Sync Done. || echo Sync Failed or Aborted.

There's a nice
article about backups with rsync at Linux.com.
I shall leave the explanations to it and just post my script as example here

I just found out there
is a
webkit KDE port, called webkitkde, with Ubuntu (372kb) packages:
Webkit is what Apple uses for Safari and Google used for Chrome.Update: This does not work cleanly if you use the kde 4.1.1 packages for hardy from the motu developers. Or to make it short: webkitkde works only in intrepid, because of wrong paths. If I have a workaround at the end.
Update2: Google Mail works with a bit of tweaking now. (I had to set Konqueror to identify as Safari 2.0 and reload the page mail.google.com.)
Update3: It's really beta software, you're not likely to have a lot of fun with it... :(. Gmail does not really work after all.
Update4: Even compiled from svn-trunk it's not really fun. There's some problem with the page loading, the fonts are too small I think. And just using khtml is much faster and more fun.
Just put this into your (Ubuntu hardy) shell:
sudo su -c "echo 'deb http://archive.ubuntu.com/ubuntu intrepid main' > /etc/apt/sources.list.d/intrepid.list"
apt-get update
apt-get install webkitkde
sudo su -c "echo > /etc/apt/sources.list.d/intrepid.list"
apt-get update
# workarounf for hardy
cd /usr/lib/kde4/share/kde4/services/
sudo ln -s /usr/share/kde4/services/webkitpart.desktop .
cd /usr/lib/kde4/lib/kde4/
sudo ln -s ../../webkitkdepart.so
# now the fine-tuning
cd /usr/lib/kde4/share/kde4/apps/ && sudo ln -s /usr/share/kde4/apps/webkitpart
cd /usr/lib/kde4/share/icons/hicolor/ && for i in 16x16 32x32 48x48 64x64 128x128; do cd $i/apps; sudo ln -s /usr/share/icons/hicolor/"$i"/apps/webkit.png; cd ../..; done;
kbuildsycoca4
And to uninstall:
sudo rm /usr/lib/kde4/share/kde4/services/webkitpart.desktop /usr/lib/kde4/lib/kde4/webkitkdepart.so /usr/lib/kde4/share/kde4/apps/webkitpart
cd /usr/lib/kde4/share/icons/hicolor/ && for i in 16x16 32x32 48x48 64x64 128x128; do cd $i/apps; sudo rm webkit.png; cd ../..; done;
sudo apt-get purge webkitkde
The README tells us:
You can switch between the different rendering engines:
View -> View Mode -> {KHTML, WebKit} (Website needs to be opened)
If WebKit does not show up in Konqueror, run 'kbuildsycoca4'.
If you want to set the WebKit part as default, run:
'keditfiletype text/html'
and move "WebKit (webkitpart)" in the "Embedding" tab to the top.

This little script helps you to quickly transcode any content mplayer accepts to an xvid avi file. It copies the audio track and encodes the video track to xvid in the original resolution in your current directory.
#!/bin/bash
# mencode.sh (c) 2008 linux-tipps.blogspot.com
# settings
BR=1400 # bitrate
lang=en # your language code for the DVD audio track, e.g. en/de/es
OUT=`basename "$1"`"-xvid-fast.avi" # output file in current directory
XVID="lumi_mask:interlacing:nochroma_me:me_quality=4:vhq=1:autoaspect:chroma_opt:bitrate=$BR" # xvid settings
# settings end
[ -f "$OUT" ] && echo File exists && exit 1;
echo Encoding $i
screen -O mencoder -alang $lang -cache 32768 -ovc xvid -oac copy \
-xvidencopts $XVID "$1" -o "$OUT";
e.g.
bash mencode.sh dvd://You may want to compile xvid and mencoder for your machine to speed it up even more, but I've already set the xvid settings to a reasonably fast mode. I get around 25-30 fps when doing a DVD to Xvid backup on my notebook.
You could add -vf scale=640:-1 but it doesn't really increase speed, but makes it look worse. I use screen, so I can detach(
Ctrl-a, Ctrl-d) from the encoding when I have to e.g. exit the current X session.
Detaching also helps to decrease unnecessary screen updates which eat cpu in many terminals. And it's better than passing -quiet as command line argument, because you now have the choice between seeing what's going on and how long it'll take or not. Screen is great... You can re-attach with
screen -r. If you have several cores, try adding threads=x to the xvid options.
Black borders are not removed. If you have an idea how to do that automatically, let me know. Interlacing is kept for a good reason: Deinterlacing slows down the process and usually also degrades the quality. Deinterlacing while playing is usually the better alternative.
By the way: The most important parts are the xvid setting me_quality=4 and vhq=1 - they speed it up a lot - and compiling xvid for your processor, because some distributions don't properly compile it, even for amd64.
You may not use this script for content you do not have the rights to transcode.

I wrote a little powersave script that quickly executes a few commands to improve battery life, esp. on notebooks. You can put it in /etc/acpi/battery.d/20-powersave.sh to start automatically when the computer runs on battery.
#!/bin/bash
SUDO=`which sudo`
SU=`which su`
EXEC="$SUDO $SU -c"
echo Activating power saving mode...
# Automatically suspend USB -- How to automatize?

# Disable CD autodetection by hal
# sudo hal-disable-polling --device /dev/scd0
$EXEC "ethtool -s eth0 wol d"
# reduce disk writes
$EXEC "echo 1500 > /proc/sys/vm/dirty_writeback_centisecs"
# SATA powersaving mode

# optimize scheduling for dual-core cpus
$EXEC "echo 1 > /sys/devices/system/cpu/sched_mc_power_savings"
# Remove fixed network adapter, intel watchdog

I have actually found a very very nice solution to the high definition video(AVCHD) transcoding problem. I got the ffmpeg svn checkout from yesterday (21.08.2008) and it works great with this script, all in one. No need for extra tools. And it's quite speedy.
#/bin/sh
FFM=$HOME/src/ffmpeg/ffmpeg
BR=3000 # kbit
OUT="${1}.mkv"
[ -f "$OUT" ] && exit 1;
echo $1
# old ffmpeg versions (2008):
nice $FFM -r 50 -i "$1" -s 1280x540 -ilme mpeg4 -acodec copy -aspect 16:9 -b ${BR}k "$OUT"
# new ffmpeg versions (January 2009): -r 50 might still be necessary.
nice $FFM -i "$1" -s 1280x540 -flags ilme -flags ildct -vcodec mpeg4 -acodec copy -aspect 16:9 -b ${BR}k "$OUT"
The only problem is that the current ffmpeg checkout does not listen to the -r parameter. So you have to manually override the frames per second when playing the file, e.g. mplayer -fps 50. I use
mplayer -fps 50 -fs -af volnorm -vf pp=fd
.
You need might need to adjust the path to ffmpeg in the script obviously, e.g. to $HOME/ffmpeg/ffmpeg.
Of course if you have a camera that records 29.97 frames per second you have to change the numbers accordingly. (-r 59.94)
If you've got several cores you may want to experiment with the -threads option and make sure you have compiled with --enable-pthreads, see below.
The great thing is that the video is encoded quickly - I get 23 fps on my celeron m530 notebook - and the video is perfectly in sync, and you only need ffmpeg, nothing else.
You should install a fresh ffmpeg from SVN:
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
cd ffmpeg
./configure --enable-nonfree --enable-gpl --enable-pthreads && make && sudo make install.
Be careful where you put every ffmpeg parameter, as ffmpeg interprets them differently depending on the order you give them. E.g. ffmpeg -r 50 -i ... differs from ffmpeg -i ... -r 50.
Enjoy fast and sync video transformation!
If it doesn't work for you, try out
this script, which is the result of the long discussions below.

This nice little script encodes avchd m2ts files from e.g. an HD camcorder directly to mpeg4 avis. It uses a temporary file in the /tmp dir for the audio stream, but the rest is done using fifo pipes. You need to install the csh shell interpreter to run it. And you need to setup the environment from this package: (by invoking ./install, then ./installasroot, you need to modify the download script and change the JM version).
The script works badly on multi-core systems, but you can invoke it several times at once. It's originally a modified version of the script from this package, but I changed it so you can run it several times concurrently (with the same file names in different folders). I also added a check to prevent it from encoding files where the output files already exist. I recommend to run it on an entire directory

If you ever (try to) use UltraVNC Single Click to help Windows users from Linux, you will find out that it's not that easy. Though you can use the UltraVNC viewer in Wine, you may see disconnects after around 15 minutes. The easy solution lies in starting a regular TightVNC with these parameters:
xtightvncviewer -listen 0 -encodings "hextile copyrect"
Replace the 0 with the display number, e.g. 0 for port 5500 or 400 for 5900. (port = 5500 + x) You need to have the package
xtightvncviewer installed for this to work in Ubuntu. The color parameter does not work properly in this configuration.
Or give
ssvnc a try. It works even with SCIII (uvnc Single Click via SSL), supports different color depths and much more!
And if you've got a current wine version, you might as well use the original ultravnc viewer. It works fine by now.
I usually use ssvn and the following script to start the vnc listener and quit it when finished.
VNC=$HOME/src/ssvnc/bin/tightvncviewer
$VNC -listen 487 -use64 & # 64 colors
read -p "Press enter when finished"
killall tightvncviewer vncviewer
