"""Demo of logging in a multi-processing context.

Based on the Python "Logging Cookbook":
  https://docs.python.org/3/howto/logging-cookbook.html#logging-to-a-single-file-from-multiple-processes

Note on `QueueListener`:

  The main difference between the Cookbook example and this demo is that I use
  the `QueueListener` convenience class, whereas they write a bespoke
  `listener_process` function which does more or less the same thing as

Normally to create a virtual environment, we can do so from the command prompt with::

    C:\Users\me>python -m venv venv

This doesn't work when we are within a virtual environment though::

    (venv) C:Users\me>python -m venv venv2
    Error: Command '['C:\\Users\\me\\venv2\\Scripts\\python.exe', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 3221226505.

Signing VirtualBox Kernel Modules

These are the steps I followed enable VirtualBox on my laptop without disabling UEFI Secure Boot. They're nearly identical to the process described on [Øyvind Stegard's blog][blog], save for a few key details. The images here are borrowed from the [Systemtap UEFI Secure Boot Wiki][systemtap].

1. Install the VirtualBox package (this might be different for your platform).

What's Cool

• Encrypted root partition
  • AES-256 bit cipher
  • Argon2id variant for PBKDF
  • Sha3-512 bit hash
• rEFInd bootloader
  • With dreary theme
  • Optimal Settings (optimized for aesthetics, and boot time)
• Boot into backups thanks to refind-btrfs
