To kill the dock in Mac OS X, in a Terminal, type:

killall Dock

The dock will shut down and  re-start automatically.  If do not want the dock to run at all—for example if you want to free up memory or free up pixels from the screen—remove the /System/Library/CoreServices/Dock.app directory with:

cd /System/Library/CoreServices
sudo mv Dock.app Dock.app.orig
killall Dock

Un-fetch git-svn revisions; Rewind git svn commits; Revert remotes/trunk branch


It's possible for an old subversion commit to be changed after it has already been committed.  One example is someone editing a commit log message for an old revision with svn propedit -r <revision> --revprop svn:log <URL>

Reduce the number of threads Boxee / XBMC / Kodi uses for thumbnailing


In Kodi/XBMC/Boxee, Canon .CR2 and other raw photo file thumbnailing speed is pretty slow. On a slow computer, using a large number of threads to generate thumbnails in parallel can use up a lot of CPU and memory and lock up the UI.

The number of threads used for thumbnailing can be reduced by creating a .boxee/UserData/advancedsettings.xml or .xbmc/userdata/advancedsettings.xml or .kodi/userdata/advancedsettings.xml file with these contents:

Make alt tab switch between all windows in Ubuntu Unity


Upgrading from Ubuntu 11.04 "Natty Narwhal" to Ubuntu 11.10 "Oneiric Ocelot" installs Ubuntu's Unity, which changes the configuration of the window switcher that is usually bound to Alt-Tab. Instead of switching between all windows, it now switches between applications.

These are instructions on how to revert the behavior back:

Installing jpegtran in Ubuntu 10.10 (a.k.a. Oneiric Ocelot)


To install jpegtran in the Ubuntu 10.10 Linux distribution, you can run the following command in a terminal window/shell

sudo apt-get install libjpeg-progs

jpegtran allows lossless rotation of JPEG images.  For example, you can losslessly rotate an image 90° counterclockwise by running:

jpegtran -rotate 270 input.jpg > output.jpg

Or you can losslessly rotate an image 90° clockwise by running:

jpegtran -rotate 90 input.jpg > output.jpg

Monitor gamma calibration for Linux / X.Org


The monica-3.7-7mdv2011.0.i586.rpm binary RPM for monica (a free monitor calibration tool for Linux) does not run in Ubuntu 11.10 (a.k.a. "Oneiric Ocelot").

./usr/bin/monica: error while loading shared libraries: libfltk.so.10: cannot open shared object file: No such file or directory

    /path/to/splunk  stop
  2. Delete all the data from a specific index (for example "main"):
    /path/to/splunk clean eventdata -index main
