Unable to boot after kernel (3.19) upgrade on Ubuntu. Here's the fix:

1. Add copy_modules_dir kernel/ubuntu/i915 to /usr/share/initramfs-tools/hooks/framebuffer.
2. Then run update-initramfs -k all -u.
3. Profit.

Fix found here: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1500751

Error:

The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes.

Solution:

# dd if=/dev/zero of=/dev/sdb bs=2048

Use dmesg after plugging in your USB thumb drive to find the device name (/dev/sdb).

# umount /media/username/devicename
# dd bs=4M if=/path/to/filename.iso of=/dev/sdb

Note, do not output to a partition (e.g. /dev/sdb1). In the past this has created a loop device instead of copying the input file to the USB thumb drive.

Forgot that one file to add during your last commit? Haven't pushed changes to a remote yet? Great! Easy fix:

$ git add forgotten_file
$ git commit --amend

Note: the following commands drop all data from the database.

$ rm -rf db.sqlite3
$ rm -rf app/migrations/*
$ ./manage.py makemigrations --empty app
$ ./manage.py makemigrations
$ ./manage.py migrate
$ ./manage.py createsuperuser

Print all digits in a string as one integer:

>>> string = "a1b2c3"
>>> integer = int(filter(str.isdigit, string))
>>> print integer
123
>>> type(integer)
<type 'int'>

Or, if you would like a list of all digits:

>>> string = "a1b2c3"
>>> import re
>>> integer_list = re.findall('\d+', string)
>>> print integer_list
['1', '2', '3']
>>> type(integer_list)
<type 'list'>

lsusb shows us that—sure enough—Apple's IR receiver is being loaded on boot:

# lsusb
Bus 005 Device 002: ID 05ac:8242 Apple, Inc. Built-in IR Receiver

lsmod reveals hid_appleir is the module being loading for our remote. Let's blacklist it:

# echo 'blacklist hid_appleir' > /etc/modprobe.d/hid_appleir.conf
# depmod -ae
# update-initramfs -u
# reboot now

That should take care of it!
