Completely disabling Akonadi in Kubuntu 11.04

Akonadi is a storage service that certain KDE programs use heavily. I only use the KDE windowing environment and I don’t use any of the applications in KDE, so akonadi was just wasting RAM and potentially CPU.

So to disable it, set StartServer=false in .config/akonadi/akonadiserverrc:

[QMYSQL]
Name=akonadi
......
StartServer=false

It might still load if you use KDE-dependent apps, or it might cause your system to blow up. But that should do the trick.

Fix a NameError: global name ‘OPENOFFICE_BIN’ is not defined in LibreOffice

Just minutes ago I upgraded to Kubuntu 11.04. I noticed that OpenOffice has been replaced with LibreOffice (yay!) so I ran a critical python-based OpenOffice script that I use, expecting it to break. It did break, but the fix is easy.

Here’s the error that the script threw:
NameError: global name 'OPENOFFICE_BIN' is not defined

All I did was to locate where LibreOffice put itself and add that to the script. In my script there’s a section that looks like this:

# Find OpenOffice.
_oopaths=(
('/usr/lib64/ooo-2.0/program', '/usr/lib64/ooo-2.0/program'),
('/usr/lib/openoffice/program', '/opt/openoffice.org/basis3.1/program'),
)

See that first instance of /usr/lib64/ooo-2.0/program? I replaced it with /usr/lib64/libreoffice/program and now the script works perfectly. Never in a million years would I expect this with an upgrade from a proprietary vendor. Once again, free open source software just saved me lots of time and money.

New script looks like this:
# Find OpenOffice.
_oopaths=(
('/usr/lib64/libreoffice/program', '/usr/lib64/ooo-2.0/program'),
('/usr/lib/openoffice/program', '/opt/openoffice.org/basis3.1/program'),
)

Fix the black screen of death playing x264/h.264 mkvs on WD TV HD player

I have a Western Digital WD TV HD media player that I really like, even though it was quickly orphaned by Western Digital as a product. Maybe someday we’ll have legislation that requires a corporation to provide a guaranteed time of product support, including software updates and bug fixes.

Anyway, once in a while the WD refuses to play a video in the Matroska “mkv” format, particularly those using the H.264 codec encoded with the mkvmerge utility. When this happens the WD basically shows a black screen and more or less locks up. Once that happens on the WD you can only eject the HD and reboot.

The fix for this is to remove video compression on the mkv in question, which sounds daunting but really is only a one-line command that takes a couple of minutes to execute and doesn’t change the quality of the video. You need the mkvmerge program which is part of the mkvtoolnix package in Ubuntu. mkvtoolnix is also available for Windows if you’re stuck there.

Here’s the command:
mkvmerge -o output.mkv --compression -1:none input.mkv

Where input.mkv is your original file and output is the fixed file.
(Edited: I changed the command to remove /all/ compression in an mkv)

Unexpected sight on the road

Driving in heavy rain the other day I did a double take as I saw this emerge from the mist.

How to make Firefox stop asking if you want to open a .zip file and always save

This message in Firefox used to pop up every time I clicked on a zip file.

You have chosen to open
foobarbaz.zip
Which is a: BIN file

Firefox 3.x, for whatever reason, greyed out the option for me to tell it not to keep asking me if I wanted to unzip the file, and I’d have to click the “save to file” option every time.

Tired of trying to figure out how to ungrey the greyed-out button, I looked for another solution. I found one in /etc/mime.types, which Firefox, among other things, uses to determine what to do with a file.

sudo vi /etc/mime.types
look for this line:
application/zip zip
change it to:
#application/zip zip

You don’t even need to restart Firefox. Firefox will now just prompt you to save the zip file /only/.

Gamemastering book finally complete

Five years, untold drafts, and 330 pages later I finally pressed the publish button on Amazon today for Gamemastering. I was an inch away from publishing it in 2009 but decided to spend more time polishing it.

I’ve got the website for the book all built out and I’m just waiting on the Amazon page to go live before I release the PDF to Creative Commons. From here on out all my blogging for the book will be kept on the official book site.

I have to say this really puts the cherry on top of a great 2010 for me.

Fix the “Using fallback suid method” error message on Busybox (NSLU2)

When you ssh into a fresh SlugOSBE install on an NSLU2 device (or maybe anything running Busybox), an annoying error keeps popping up: “Using fallback suid method”

The simple fix to this is, as root:
touch /etc/busybox.conf

That’s it.
