Ubuntu 16.04 Runs Automatic Updates Whether You Say So or Not in the Installer

After selecting “No automatic updates” in the Ubuntu 16.04 server installer, I expected that the system would not attempt to upgrade anything without my permission, just like every version before. Turns out that is not the case. I found out the hard way when my production database shut down to upgrade in the middle of […]

Install zfs-auto-snapshot on Ubuntu 16.04 LTS/Debian

zfs-auto-snapshot not being available for 16.04 was not a situation I thought I would run into, yet here we are, disappointed by Canonical once again. In the meantime, I have ported the package from Trusty (14.04.5) to work on Xenial (16.04.1) and Debian Jessie. You can download the Ubuntu 16.04 package here, and install it by […]

Install Steam Games to SMB Share on Linux

I use an SSD and can’t install all my Steam games onto my SSD. I don’t have a large HDD in my workstation as all my files are on my huge ZFS file server. I simply wanted to install Steam games onto the share. Seems simple, right? I used to bind (using mount) the steamapps […]

Fix ZFS Array Appearing Corrupted When Adding A Hot Spare

Yesterday I assembled a new ZFS array. It’s a 7x 1TB SATA RAID-Z1 array. Having to replace a failed drive within the first hour of the array’s life, I decided adding a hot spare would be a good idea. After installing it in the server (hotplugging) I checked with dmesg that it was detected as […]

Fix FLAC Files Not Playing on Android

A long time ago I bought an ASUS TF300T Android tablet and have been very happy with it. The only thing that it never did correctly was play FLAC audio files. According to Google, all versions of Android after 3.1 can natively play FLAC files, and since my device runs 4.1 it should be no problem, right? […]

Simple Domain Controller With Samba

I’ve had many people ask me over the last week how to set up a simple Windows domain with a Samba primary domain controller. This is a pretty complex topic and can get really messy really fast. This “guide” (if you can call it that) assumes that you have Ubuntu 12.04 installed on a server […]

Recover RAID Array With dmraid

I woke up this morning and what do you know, one of my RAID arrays in my workstation was degraded. Just great. This particular array was made up of 3x 1TB disks in RAID level 5 running on an Intel RST fakeRAID controller. After Ubuntu had some serious difficulty communicating with the drive on bootup, […]

Fix Vuze Not Starting on Linux

Just a few days ago, my Vuze installation on my Ubuntu powered server simply stopped working. It would start and almost immediately crash. In my case, the problem was caused by the Java Standard Widget Toolkit (SWT) library being 64-bit, while my server OS is 32-bit. This architecture mismatch caused the crash. I have no […]

Never Install 3rd Party Drivers

Driver – every Windows user cringes at the utter sound of the word let alone the thought of having to deal with one. Regardless, they are required in order for your software to interact with hardware properly (or at all). The manufacturers of computer peripherals and components usually provide the drivers for their own equipment, and so […]

How To Universally Compare The Performance of Processors

  Like me, you want to get the most out of your money when it comes to a new computer, and that usually means the most speed for the lowest price. When looking at a computer’s specs, you are usually given the speed of the computer’s CPU or central processing unit (the computer’s main processor). […]
