Windows 7 install ISO with slipstreamed updates

Preparation

Create three directories. For the sake of this tutorial, they will be:

• c:\image - holds the contents of the ISO file
• c:\mount - mount point for the install.wim file
• c:\updates - holds the update files

duplicity -> Backblaze B2

Daily systemd timer to backup the contents of my filesystem to Backblaze B2. As-written, it will keep up to a year's worth of backups, performing one full backup every month. This script was tested with duplicity 2.1.0.

Configure the script

Create a B2 bucket and an application key with read/write permissions to that bucket. Configure object lock with a sufficiently long period (I use 3x the full backup period) to ensure that ransomware won't be able to nuke your backups. Also ensure the 'list all bucket names' option is enabled (unless you want to use the

T450s Arch Linux installation

This documents how to install Arch Linux on a ThinkPad T450s, with full disk encryption and UEFI secure boot. It assumes you're familiar with installing Arch Linux, but new to encryption/secure boot. It does not install a bootloader (UEFI comes with one built in), and assumes you are not going to dual boot another OS.

(The instructions here should work fine for other devices too - just ignore the ThinkPad-specific bits)

Wipe the hard drive (optional)

My T450s has issues with using hdparm to wipe the disk, so instead we will use the drive erase utility provided by Lenovo. This section is mostly copied from this tutorial.

iOS notes

Just some random stuff I'm learning as I make my first iOS app.

UIViewController: present vs show

present() will always show the view controller modally, whereas with show() it will bubble up the chain where it can be handled by some parent view controller.

# Sync music from Linux to iPhone using libimobiledevice + ifuse
# Only works with apps that can read songs from iTunes file sharing (e.g. Doppi)

    echo "usage: $0 <src dir>"
