In order to securely wipe an NVME drive you can use the nvme-cli package that provides the nvme command nvme only exists in the root path so you have to use sudo nvme.

For Debian you need to add jessie-backports (on jessie) and it may be in the newer version default repos. For Ubuntu it should be available in the default repos from Xenial onwards, there may be a PPA if you need it on earlier versions.

You can find your devices with sudo nvme list and securely format with sudo nvme /dev/nvme0n1 --ses=1. You can also explicitly add a namespace but I haven't seen or setup a drive with multiple yet.

ASUS makes a pretty handy Chromebox, and it's handy not just because it's running ChromeOS, it's handy because of everything you can do to the box itself.

The ASUS Chromebox is easily upgradeable, and capable of running just about any linux distribution.

The model I picked up, the M004U has the following specs:

  • Celeron 2955U (1.4GHz) 64 bit Dual core processor with 2MB L3 Cache
  • 2GB DDR3 1600 RAM with 2 slots
  • 16GB SSD HDD
  • 802.11 b/g/n dual-band wireless, Bluetooth 4.0, and gigabit ethernet

Based on info from but with modified behavior and fixed to work with iTerm2 version 3 or later. It will not work with older versions of iTerm. The modified behavior is to open a new terminal window for each invocation instead of reusing an already open window. Update - The original author released a build script for the newer iTerm2 versions at that keeps the original behavior of reusing an open iTerm2 window.

To open iTerm2 at selected folder with keyboard shortcut

  1. Run Automator, select a new Service
  2. Select Utilities -> Double click ‘Run AppleScript’
  3. Service receives selected 'folders' in ''
  4. Paste script:
