VirtualBox - Cannot Register the DVD Image

Everything was working fine... Then I copied some VBox 'computers' back onto my hard drive. I suspect that I may have upgraded the VBox software during the time that they were offline - I am not sure.

Anyway, a couple of hours later, i restarted my computer and went to start up the VBox session i had just been working on. I got the following sort of error:

VirtualBox on OpenSuSE

I don't have a dedicated Windows box any longer. Even though I much prefer OSX and unix flavours like OpenSuSE, there are times one needs access to Windows. Sometimes the work one does for a client requires it - that is the situation now on one of my contracts. I've had great results using VirtualBox. I used Parallels for the first year, but switched about 3 years ago and have never looked back.  The only thing that had me worried was that I only had it on my Mac - what if the Mac was acting up or had a hard drive crash? (It can happen to any computer, Macs included).

Drupal Danland CSS Styling

One of the worst mistakes a newbie can make is to modify theme files directly. Sometimes it is necessary, but it's preferable to either sub-theme, or use a local.css file to provide your own overrides. That way you can upgrade the core theme without overwriting all your work. Don't sweat it - we've all done it - but try not to do it any longer....

The Danland theme that I like supports a local css file - local.css. Anything in this file replaces directives in the base style.css file.

How Do You Know Your Site is Active?

Even though I took this new site live a few weeks ago, I haven't been checking the access logs much to see what sort of visitor activity I've been getting. I knew that the web crawlers are visiting, but the last two days I received a sure sign - spammers have been leaving comments!!! I've been deleting them of course. It's a strange mixture of annoyance, and glee..

Monitoring Disk Health

I have just been looking into automated monitoring of disk health.

In my copious smare time (ha!!!) I am recovering data form two failed MyBookWorld NAS units - they seemed like a great idea at the time but they just kept failing disks. Fortunately they were configured as RAID drives so even if one disk failed, the data was on the other... So I pulled the disks out and am attaching them to a unix box and recovering the data. Once that is complete, I will want to continuously check on the ealth of these (and all my disks).

Fortumately, unix has the smartctl program.

OpenSuSE 13.1 Upgrade Getting Black Screen of Death

The first few times I tried to do an upgrade of OpenSuSE from 12.2 to 13.1, I got a Black Screen of Death right after i selected "Installation" from the first menu. I tried rebooting a few times, then wondered if it was something about the screen resolution. It was.

On the menu that presents options like "Boot from Hard Disk" and "Installation", there are some options at the bottom of the screen. One of those was for the screen. Rather than letting it automatically decide, i set it to 1024x768 and then ran the Installation option. It worked great. FYI in case this happens to you.

OpenSuSE 13.1 Network Install

How do you install OpenSuSE 13.1 if you don't have a DVD drive (just a CD) and the computer won't boot from a USB key? That was my quandry. So i tried the Network Install.
