Boot Live Disks from a Multiboot USB as an ISO

Normally when you want to boot from a USB stick you have to format it and ‘burn’ an image onto it. It is possible to make multiboot usb sticks that allow you to boot ISO image file directly. Not all live system images, like the Ubuntu desktop images, play nice with the method outlined in that post. Here is an alternative method that will allow you to boot images like Ubuntu desktop as an ISO from a multiboot stick. »

The New and Improved wdullaer.com

A bit over a year and a half ago I moved my blog to Github pages and Jekyll. The promise of no hassle/maintenance blogging that static website generators offer (combined with, let’s be honest, free hosting) was very luring. By and large this setup has delivered on its promise, but it was definitely not perfect. Recently the ever present desire to improve (and experiment) got the best of me and I started working on the backend of this blog again. This post tries to describe all the changes I’ve done, and why I’ve done them. »

Create a NAS with Redundancy Using Snapraid

Like a lot of techie people, I run a home server to centralize access to music, video’s, photos and other files. Because I have built my own server using a HP Proliant Microserver running Ubuntu, I need to do a bit more work myself in order to group my disks together in a redundant pool. This post will focus on how I’ve configured AUFS to expose my disks as a single volume and configured Snapraid to add redundancy and bitrot protection to the data. »

Pass Credentials to the awslogs Docker Logging Driver on Ubuntu

Last year docker added support for multiple logging drivers. This makes it very easy to integrate your docker containers with a centralized log management system in a transparent way. If you want to use the AWS Cloudwatch driver you will need to supply the docker daemon with access keys, which proved to be trickier than expected. Here’s how I managed to get it running. »

Multitouch Trackpad Gestures with Touchegg

Support for multitouch gestures on Linux has been steadily increasing in the past years. I recently bought a Logitech T650 touchpad and all the basics worked right of the box: moving the cursor, two finger click for right click, two finger swipes for scrolling through documents. Unfortunately it wasn’t immediately obvious how I could configure anything more (like pinching gestures, or 3 finger gestures). Here’s how you can unlock its full power. »

Firefox Desktop Reader Mode

The reader mode in the Android version of Firefox was released a few years ago with a lot of fanfare. In a recent update, the desktop version received the same functionality, but it doesn’t seem to be enabled by default on all installations. »

BubbleUPnP Server with Systemd on Ubuntu Vivid

Starting with Ubuntu 15.04, Canonical replaced their own init system Upstart with the new Linux standard Systemd. Even though this is a big change on a technical level, it was entirely transparent for all packages in the official repositories. BubbleUPnP Server, a closed source third party application, was the only application I had any issues with. I’ll show you how you can make it work with systemd. »

Comparison of RAID-like Systems for a Home NAS

There are a lot of ways to configure a server with multiple disks as a redundant network attached storage device. Most rely on RAID-like systems, but there are alternatives. In this post I compare a few of those systems and explain why I chose to use AUFS combined with snapraid. »

Hack your WD Greens

WD Green and Red disks are physically identical, with only a firmware setting distinguishing them. The default settings on a WD Green will cause them to die prematurely when used in a file server environment. Fortunately you can change this setting very easily. Here’s how. »
