PayPal used to let you create a payment link in addition to the current payment button. The link was nice for a quick and dirty method when the button wasn’t needed, but PayPal seems to have done away with it. The link below brings back the functionality. Thanks!

I often want an easy command line way to easily backup a standard definition (non-BlueRay) DVD to and ISO image. The command line is nice because I can do it remotely on an idle MythTV Frontend machine and can copy the resulting ISO right to the mounted Movies folder.
Get DVD Info
dvdbackup -i /dev/dvd
Backup whole DVD
dvdbackup -i /dev/dvd -o ~ -M
Make ISO
mkisofs -dvd-video -udf -o ~/dvd.iso ~/MOVIE_NAME
The information was taken from here: https://wiki.archlinux.org/index.php/Dvdbackup
I hate manually cleaning out all of the old kernels here is a script to do it for you:
dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge
This was stole directly from here.
For good measure I run the following after to be sure the grub config is good:
sudo update-grub2
Reboot to make sure everything is OK.
Which much restraint I avoided including several bad un-popped popcorn references.

The little light to the left of the Clean light on the 500 series, which if it is there can look like either a little Roomba or an exclamation point is called the Check Robot light (according to the Customer Service rep on the phone who e-mailed me the info below).
If your Roomba’s CLEAN light is blinking orange and the Check Robot light illuminates, the robot is experiencing a charging error. The Check Robot light will blink out the error number every 2 seconds. For example, if the robot has an error code 2, it will blink twice, pause for 2 seconds, blink twice, etc.
Please watch your robot when the CLEAN light is blinking to determine what error code your robot is displaying. Please respond with this information so that we can assist you further.

This was written for Fedora, not sure how many other other distros it applies to.
There are three ways to change your runlevel:
* While the Computer is Running:
1. Open a Terminal.
2. Become root.
3. Type:
init number
where number is the runlevel that you want to change to.
You will then be switched into the new runlevel.
* While You Are Booting the Computer:
1. When you first start your computer, the GRUB screen (where you choose your Operating System) appears. Select the Fedora that you want to boot into, but press the a key instead of pressing Enter.
2. You will see a line somewhat like the following:
kernel /vmlinuz-2.6.9-1.667 ro root=LABEL=/ acpi=on rhgb quiet
Add the number of your runlevel to the end of that line, and then press Enter. For example, to boot into text-only mode, the line would look like:
kernel /vmlinuz-2.6.9-1.667 ro root=LABEL=/ acpi=on rhgb quiet 3
You will then boot into the new runlevel this time only.
* Permanently Set a Default Runlevel:
1. Open a Terminal.
2. Become root.
3. Open the file /etc/inittab in your favorite text editor:
gedit /etc/inittab
4. Find the line:
id:number:initdefault:
where number is your current default runlevel (probably 5).
5. Change the number in the middle of the line to the new runlevel that you want your computer to start in by default. For example, if you want to start in text-only mode by default, change it to:
id:3:initdefault:
You will then boot into that runlevel every time you start the computer.
I played with 2 options:
TrueCrypt and FreeOTFE
TrueCrypt has a Windows and Linux GUI making it pretty easy to use cross platform. It also do some pretty cool encryption of the boot drive to secure the whole computer, but I haven’t messed with that yet.
FreeOTFE has cool because it has a WIndows GUI and can automount under linux if you encrypt a whole partition as opposed to a volume (file) stored on a partition. I really wanted to go with FreeOTFE for the automounting, but ran into a deal breaker issue. Windows can only mount a single partition from a USB drive, so I couldn’t have a small partition to run FreeOTFE from (so it was portable to any Windows computer) and have a 2nd large encrypted partition for the data.
Configuring FreeOTFE and Linux see http://emcken.dk/weblog/archives/164-encrypted-usb-drive-in-ubuntu.html. My notes just in case the above link ever goes away:
sudo apt-get install cryptsetup
sudo modprobe dm-crypt ## If you haven’t rebooted
sudo cryptsetup –verbose –verify-passphrase luksFormat /dev/sdb5
sudo cryptsetup luksOpen /dev/sdb5 sdb5
# Based on fat32 or ntfs
sudo mkfs.vfat /dev/mapper/sdb5 -n “tpearsall”
sudo mkntfs -f /dev/mapper/sdb5
sudo cryptsetup luksClose sdb5
