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>

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:

In gconf-editor:

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

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

To remove all of the data from a specific Splunk index without using the slow "| delete" command:

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

A group at UCSD is actually developing an odor output device.

If the locate database hasn't been created yet on a Mac OS X 10.6 (Snow Leopard) computer, the message:

The plugin formerly known as Map Color Range in GIMP 2.2 and Color Range Mapping in GIMP 2.4 appears to have been removed in GIMP 2.6.

One way to get it back is to just grab the plug-in file from a previous version.  For example, you can run:

wget http://download.fedora.redhat.com/pub/fedora/linux/releases/9/Everything/i386.newkey/os/Packages/gimp-2.4.5-1.fc9.i386.rpm

rpm2cpio gimp-2.4.5-1.fc9.i386.rpm|cpio -idvm

At first, I thought I had been hacked:

How do you see or find untracked files in your Git working copy that Git ignores?

Files which do not show up in git status because they match a pattern/line in .gitignore or .git/info/exclude with this command:

Git 1.6:
git ls-files --others -i --exclude-standard

Git 1.4, 1.5:
git ls-files --others -i \
--exclude-from="`git rev-parse --git-dir`/info/exclude" \
--exclude-per-directory=.gitignore
