yum -y install ffmpeg ffmpeg-devel
wget http://sourceforge.net/projects/ffmpeg-php/files/ffmpeg-php/0.6.0/ffmpeg-php-0.6.0.tbz2/download
tar jxvf ffmpeg-php-0.6.0.tbz2
sed -i 's/PIX_FMT_RGBA32/PIX_FMT_RGBA/g' ffmpeg-php-0.6.0/ffmpeg_frame.c
cd ffmpeg-php-0.6.0 && phpize
./configure && make && make install
echo 'extension=ffmpeg.so' > /etc/php.d/ffmpeg.ini && /etc/init.d/httpd restart
php -v && php -m | grep ffmpeg

In this process you:
use yum to install ffmpeg and the ffmpeg development files
download php-ffmepg from sourceforge and extract it
apply the bug fix to the ffmpeg_frace.c file
change directories to the php-ffmpeg directory and phpize the module
configure, make and install the shared object (extension)
add the extension to the loaded php extensions
restart apache and verify no errors are shown on php startup and that ffmepg is loaded

If all is well, you should see your version of PHP with the copyrights on 3 lines and the last line showing ffmpeg

find /etc/apache2/sites-enabled -name "*com" -exec sed -i 's/8080/80/g' {} \;

Enter the following command to turn all the bits on the drive to 0

dd if=/dev/zero of=/dev/sdb

Wait a few hours and you have a completely wiped disk drive

#Ubuntu/Debian
sudo apt-get install imagemagick

#RedHat, Fedora, CentOS
sudo yum install imagemagick

After that, it’s super easy.

mogrify -resize 800 -rotate 90 image.jpg

The above command would resize image.jpg to 800 pixels wide maintaining aspect ratio and rotate the image 90 degrees clockwise.

To define your own dimensions (discarding aspect ratio) use the following:

mogrify -resize 800x600! -rotate 90 image.jpg

The above command does the same as the other, but resizes to 800 x 600.

No more need to open GIMP just to resize and rotate an image!

Above is a simple bash script to backup a directory after making a PostgreSQL data dump. I left a lot of my original code in place so you can see how to work with directories that have spaces. The trick is to escape when you use double quotes and do nothing when you use no quotes.

I also told crontab to run this file every day by making a crontab file:

cron.txt

30 5 * * * /home/user/cron/backup-script.sh

Then telling crontab to use the file

crontab -e cron.txt

sudo npm install socket.io

First we change to our home directory via cd ~ … even though the tilda in the code above looks like a hyphen. Then we install Google V8, SSL development files and cURL. Next we grab Node.js, configure and install it. Nearly last, we download and install npm. Finally, we tell npm to install socket.io for us.

fin.
