A rebuild of an abused Dahon foldable bicycle

It is time for some bike photos! Last year I purchased a used foldable bike through an on-line auction for what seemed like a bargain price. Despite being in a deeply sad and abused state that bike looked cheerfully yellow. The bike also came with a bull-horn handlebar and road-bike STI shifters. It’s not difficult to come up with an excuse to buy a new bike. For that reason I could easily justify a foldable bike as means to do quick errands, like getting to the closest car sharing station.

Build a computer system from scratch

Customized disposable desktop VMs, fast!

Provisioning VMs on-demand from scratch with Vagrant, Packer and Arch Linux

I’ve been running virtualized desktop environments for a couple of years now, doing various tasks from within Virtualbox VMs. I like the fact the tools and libraries for the job at hand are isolated from other environments. But I have been missing on the dynamic aspect, somehow ending up with VMs which are as prone to maintenance as physical installations. Recently, I’ve decided to solve this issue once and for all with the help from Arch Linux, Vagrant and Packer.
