About Us

onelittlewindow is a blog by Douglas Wilson and Mark Bristow.

We’re both on twitter (Doug is @dallendoug), but we’ve recently just started an account for the blog (@onelittlewindow) if you want to follow us there.

The name derives from a brainstorming session a while back for a project which may never see the light of day, but it also doubles as a blog title for now — it’s one little window on our world, which is a mash-up between information and application security, application and system engineering and architecture, writing, and the curse of being alive in “interesting times.”
