Can you stand on your head?

Thursday, 13 May 2010

I've been a little quieter than usual recently, having spent more time outdoors putting cute people in front of the camera. However that said I've still been doing some things. Most interestingly I've given away my first ever project.

The collection of small scripts known as xen-tools (which was initially a sleazy hack to go with a small introduction to Xen article) has now got new developers, and a new home where development is continuing.

This isn't the first time I've stopped working on something, but it is the first time I've explicitly "given away" a project. (Mostly on the basis that if I didn't care nobody else did either, or people cared but were too busy/unable to actually do soemthing useful.)

I'll be following new updates with interest, even though these days I'm 100% Xen-free. No need to go into huge details about why, but I'm enjoying KVM.

Having said that I recently got into a huge mess with a combination of LVM, KVM, and ext3. I've written up the details on ServerFault in the optimistic hope that somebody will report having experienced a similar problem. If you have seen something similar I'd love to hear from you.

Otherwise I'm genuinely at a loss to understand what went wrong, and why things failed. I could suspect hardware issues, but that feels like a cop-out, albeit one that has a potential solution (Mad Hatter: All Change!) rather than my current answer and explaination "It broke. I don't know why. It might happen again. It might not. Trust me?".

You Greeks take pride in your logic. I suggest you employ it.

Tomorrow, all being well, I'll receive a new computer.

I've always run Debian unstable upon my desktop in the past, partly because I wanted to have "new stuff" and partly because I needed a Debian unstable system for building Debian packages with.

However I'm strongly tempted to just install Lenny. I use that upon my work desktop and it does me just fine for surfing, building tools, and similar.

I can use pbuilder, sbuildd, or similar to build packages for upload to Debian, and if I want to experiment with new-hotness I can use a KVM guest or two.

Providing the hardware works with Lenny (and I have no reason to believe it won't) then there's no obvious downside I can think of.

The only potential complication will be restoring my backups, it is possible that my firefox databases, and similar things, might not work on older version. Still we shall see.

I plan to install software RAID, and run the system on LVM because quite frankly it rocks. Unless my current system fails in the next 24 hours I can use that to do the installation (My current desktop acts as a TFTP/DHCP/NFS server so I can use it to PXE-boot).

Anyway now I need to go eat food, tidy my desk, and decide what to call the machine .. At the moment the choice is between "march.my.flat" and birthday.my.flat, as my 34th birthday is on March 10th.
