Mac Trick – Invert Screen Colors

To invert the colors on your mac, use the shortcut ⌘ (command key) + option/alt + control + 8 (all at the same time). For those not confortable with shortcuts, you can do the same by going to  (Apple logo at upper-left hand corner_ -> System Preferences, and clicking “Universal Access” under Personal. From there, checking ‘White on Black’ will have the same effect.

Take a look at the two images below of what my screen normally looks like, and what my screen looks like when the colors are inverted

Do keep in mind if you take any screenshots in the ‘inverted color’ mode, the screenshot will not come out with inverted colors. If you would like to have inverted colored screenshots, you must manually invert the image in an image editing program.

Installing recordmydesktop on CentOS and RHEL

Recordmydesktop is a command line (and GUI) program that can be used to record a video of the CentOS Desktop (among other distros as well). To install it on CentOS, begin by installing the required dependancies:

yum install gcc make libXext-devel libSM-devel libICE-devel zlib-devel libXfixes-devel libXdamage-devel libvorbis-devel libtheora-devel

Because CentOS does not official an RPM for recordmydesktop, we will have to install it from source. We will download a tar of the source code, untar the source, and remove the tar file:

wget http://downloads.sourceforge.net/project/recordmydesktop/recordmydesktop/0.3.8.1/recordmydesktop-0.3.8.1.tar.gz
tar xf recordmydesktop-0.3.8.1.tar.gz
rm -rf recordmydesktop-0.3.8.1.tar.gz

Now, let’s go into the folder and install Recordmydesktop.

cd recordmydesktop-0.3.8.1
./configure
make
make install

If you did not set a custom prefix, running /usr/bin/recordmydesktop should begin recording your desktop! Use the following command (just as with most commands) to view the options available:

recordmydesktop --help
