Installing an Ainol Novo 7 Paladin Tablet in Linux (Ubuntu)

I recently got one of these, and I love it.  But I'm doing some Grails development in Windows, for which I needed Java 7, 64-bit - so I've taken to doing my Android development in Linux.

While trying to install the tablet in Linux I came up against something I hadn't seen before... abd devices gave me the following output:

Fail2Ban - blocking brute force attacks against Dovecot

Recently I noticed an absolute deluge of failed logins to Dovecot, thousands of attempts - here is a small snippet:

CTRL-ALT-BACKSPACE to restart X Windows in Ubuntu 10.10

Recently I started to have a problem with my new 22" flat panel where it won't wake up from sleep - leaving me with just my laptops display running.  Pulling the HDMI plug and re-inserting it works in Windows 7, but not in Ubuntu - I get a popup message stating that the discovered monitor cannot be enabled as the new display configuration doesn't fit - or words to that effect.

Accessing shared Windows folders in Sun (Oracle) VirtualBox

I've used Sun VirtualBox (Now Oracle VirtualBox) for a couple of years as a handy way to run Linux on my Windows-based laptop.  It broke a while back and I only just got around to reinstalling it using the new 4.0.0 release - and found shared folders didn't work out of the box.  I could set one up - and I could see it - but it wouldn't allow me access - I got the following error:

You do not have the permissions necessary to view the contents of "sf_virtualbox_sharename"

Ubuntu 10.04 Minimise Maximise Close buttons on the wrong (left) side...

UPDATE 2: Ubuntu 16.04 has blocked the ability to change this - good on you, assholes.

UPDATE: Ubuntu 13.04 requires a different fix, I've added it below

Well, I love the new release of Ubuntu...  but I really don't like the new layout of the min/max/close block... And nor do a lot of other people by the looks of things: it got its very own bug track with a massive number of posts on it (#532633).  Well, this is all fine, its Linux - I can change it... can't I?...

Ubuntu 9.10 and Sun VirtualBox

As part of my C programming course recently I needed a Linux environment to work in, so decided to give Sun VirtualBox a try as a way to run Ubuntu 9.10 on my Laptop (running Windows 7).  It works well, but required a little tweaking to get going properly.

First, you need to install guest additions - to do this you need to choose it from the devices menu at the top of the VirtualBox window... this mounts them as a virtual CD ROM drive in your Linux install.
