Intel NUCI decided to move my home backup drives to ZFS because I wanted built-in file checksumming as a prevention against silent data corruption. I chose ZFS over BrtFS because I have considerable experience with ZFS on Solaris.

I knew that ZFS loves RAM, hence I upgraded my home “server” (NFS/Samba/Docker) from an old laptop with 2GB of RAM to the cheapest Intel NUC I could find with USB3, Gigabit ethernet and 8GB of RAM. The C5CPYH model fitted the bill.

Two remarks for those that want to install Linux on this barebones mini-pc:

  • Update the BIOS first, otherwise the Ubuntu 16.04 server USB installer won’t start. My model had a very recent BIOS version, but still I needed the latest. BIOS updates can be found here. (There is also an option to select Linux as the OS in the BIOS.)
  • Ubuntu 16.04 server did not find the network card at install time (missing Realtek drivers). Just finish the installation. Once rebooted, the correct driver for the network card will be already loaded. Just finish the IP configuration in /etc/network/interfaces.

Define the main screen in Ubuntu Unity dual screen setup 2011-05-13

I use a dual screen setup at home. On the left side I have a big lcd screen and on the right the fixed screen of the laptop (on a docking station). The big screen is my main screen, while the smaller screen is for things I like to keep open like mail or an irc session (ssh+screen+irssi).

In this new install, the unity global menu can be found on the smaller screen.This probably makes sense on a lot of setups, but I prefer this icon menu on my main screen as it feel more accessible (it’s physically closer) and it autohides anyway.

I did not find a graphical way to set this up, but editing the configuration file is very easy:

$ vi ~/.config/monitors.xml

or if you prefer a graphical editor:

Press Alt + F2 and type “gnome-text-editor ~/.config/monitors.xml”

Identify you main monitor (name, resolution, etc) and change “no” into:


That’s it.

VirtualBox: Install Windows XP using pbx boot 2008-06-24

VirtualBox is a great product for a developer (or even a regular user) to run several OSes simultaneously. I run Linux on my laptop, but I need a Windows partition with certain software and updates to connect to the work network. A virtual machine is a fine solution. Specially when running in seamless mode (only the program is open in your Linux desktop and not the complete Windows desktop).

Installing Windows from cd on a VirtualBox instance is really easy. However, I need a *specific* windows installation that can only be installed from a Windows PXE server at work. Sadly, the virtualbox open source edition delivered with Ubuntu 8.10 is unable to do this. This is what I did: (more…)

Using nano as the default shell editor is probably a great choice for a Gnu/Linux distribution (also) aimed for Unix newbies. If you know your way on the command line however, you’ll scream from frustration for every “i”, “:wq!” or “ZZ” you type and you see the characters in the text you are editing. Specially frustrating in cron. If you don’t know what “i”, “:wq!” or “ZZ” do, don’t worry, nano is working fine for you. (more…)
