New computer is working in a nice stable fashion although with no working USB for no reason that I can fathom. (Plug in a device and nothing happens. No kernel messages, etc)
I will document this properly a little later, and update the map to match.
All told the new machine is:
- Motherboard: Nvidia Nforce N570 SLi Chipset
- Processor: AMD X2 AM2 4200 Dual Core
- Memory: 1Gb. (2+512Mb)
- Disk: 1+320Gb SATA drive.
- Graphics: PCI-Express ATI Radeon Extreme AX300SE
The graphics give me 1280+1024 which is as much as I can handle on my 17" TFT display, and didn't require any non-free drivers.
I wandered into a couple of local stores and said "I'm looking to buy a graphics card, what do you have in the PCI express flavour?". The answers ranged from:
- Nothing .. sold out.
- NVIdia .. something .. £100+
- ATI Radeon £39.99
So whilst I wanted to get an NVIdia card since they traditionally have had drivers which work for me I was happy to get the cheaper one and hope for the best. As it turns out I'm using xserver-xorg-video-ati with no problems and playing DVDs over NFS works without any visible lagging/artifacts/errors.
The system has 512Mb to itself, and the rest set aside for Xen guests. Right now I have six instances of Sarge running with 64Mb each. Things are nice and snappy :) (Since debootstrap failed on the 64 bit install of Sarge I had to download pre-made Sarge images, but still a painless process.)
Talking of Xen I found a weird problem where when starting up a new Xen guest the host would lose networking. I think this is an artifact of the NVidia 4 chipset - but adding irqpoll to the boot flag(s) seems to have fixed it.
OK enough about my new toy(s). Happy Holidays
(No complaints about my new cheesy Christmas Logo yet. Result!)

My Christmas day was primarily spent at home watching Red Dwarf.
Apart from that I made new releases of xen-shell and xen-tools.
I was suprised to recieve a sudden flurry of bug reports. No less than ten bugs reported by two users in one day! Still I fixed most of them and made a new release.
It was nice to notice Isaac Clerencia writing about using xen-tools for automated testing. The idea has occurred to me before: Create a fresh Xen installation of Debian then run a test suite and trash the system afterwards. I even setup a test Yawns builder for a while.
Are people finding interesting users for xen-tools? I'd love to have some use-cases, and more user-feedback is always appreciated. Feel free to get in touch or comment here.
Personally I use a few Xen guests on my home LAN and I regularly create new Sarge images for building backported Xen packages. Only recently did I move my home cfengine setup onto a domU.
In other news I recently received a copy of Programming Ruby from my Amazon wishlist, I'm learning a lot about Ruby and I think I'm in love. The only downside is the mental confusion I experience when I see "@variable" and "$variable" used. I am too wedded to Perl to stop thinking "array" and "string" respectively.
I should find a toy project to write in Ruby to get used to it. Right now nothing occurs, but I'm sure it is just a matter of time.

Only three things to say today:
- Second anniversary
Today marks the second anniversary of the Debian Administration website.
(I think that this is the first public mention of my intention to setup the site. It was the earliest I could find anyway.)
- Edinburgh Trivia
Doing my own small bit for Debconf I went for a walk on Christmas Day.
For two years I've lived in the area of Edinburgh known as Leith. (Famous for being a port, and being a port of call for hookers)
During that time I've taken buses, and walked, up and down Leith walk hundreds of times. Almost every time I do I notice a large chimney by The Edinburgh Playhouse Theatre.. The top 20/30ft of the chimney can be seen from peeking over the top of local buildings, assuming you're not blocked by other buildings. And now?
Now I know what it sits upon.
My little adventure in getting to know the city I've been living in; I wanted to find the bottom of the chimney and see what it was attached to. So if anybody coming to Debconf next year gets massively lost and curious about a large chimney en route to my house .. I can tell them all about it.
It is the little things in life ..
- Xen Shell
I'm not sure that there are many people using this, the freshmeat listing has a few subscribers but I'm never sure how well that translates. (Plus of course nobody rated the software so it might be they hate it?). Anyway there are almost certainly far fewer users of the shell than the main xen-tools package - but as of last night the shell now allows you to control more than one Xen instance.
This is quite a large change, since previously it explicitly only supported one user controlling one Xen instance. Expect a new release shortly once I've tested it more, and updated the documentation.
