This is a small Perl6 script that scans a folder for the .pdf documents and .url files to generate an application menu. This menu can reside in a menu bar such as that offered by Xfce's menubar panels. The script will also mimic the folder's subtree structure to create submenus. This provides immediate access to a large library of documents and links right from your desktop.

Perl6/Rakudo is really great at performing these sorts of fs-tree scan/visit algorithms, especially where it needs to actually parse certain files in order to scoop out the relevant contents.

The libvirt documentation gives an example of how to pass a device by its idVendor and idProduct numbers, but what if you have several devices with the same numbers?

This quick tip shows how to pass in a USB device using the "bus:device" address format.

Here we build a lightweight VM for kernel and device development by leveraging LVM's thin logical volumes. Thin volumes are easy to copy, destroy, and clone. They facilitate a "stateless" VM whose rootfs is immutable between runs -- like you'd see in a container environment.

Statelessness provides all the benefits of a sanitary development environment while still allowing us to pass in a guest kernel that we can recompile in the host.

Here's how to set it all up.
