Have you seen this article ?
Hay:
In ComputerWorld mag there is an article about save backups on CD's.
The gist is that its not a good idea for long term storage. i.e.
more than about 2 years.
I did not know this.
Guess its a good thing Sun has a tape storage solution.....
Here is the article link.

I had always assumed that they where making some kind of mark on a metal
foil inside of the plastic. Guess thats what I get for assuming.
I wonder what the storage life is if you keep the CD in a dark cool place.

Where have I been lately....
During the July 4th break, my wife and I went packing in the mountains. Still lots of snow
and ice up there. Got some pictures of a frozen lake, but not much else to say about the trip.
Well, not true, my wife fell through an ice bridge and sprand her knee. Should be o.k. in a
few weeks.
I'v been heads down in power management code for months, but we are starting to daylight now.
There will be some kind of description of our work at the OpenSolaris meeting, end of the month.
So, how about that stock....
Diving deep on work again.

New Look.
So, I was shopping around on the blog server and found a page theme called 'x2'.... being in the X group, x2 seems like a natural.

I have to admit that I'm in two minds on this:
1. Like showing your high school class pictures around. No idea what people will think.
Geek or Cool.
2. On the other hand, I can't wait to see what people will do with the code. Should be fun!
So, I guess we will be pushing the Sun version of Xorg out latter this year. There will be
some changes there, but most of the goodies are already back at Xorg now. The other
day we (X group) where at the OpenSource user group, someone asked if we are planning
to publish our Frame Buffer Power Management code. At this time I'm considering
putting out via Xorg first. I want some review of the design first. You'd think its
easy to turn off the video board.... right!
oh yeah, I gotta work now.

Lately, we'v seen LCD's get to very large formats. Not just inches across, but dots per inch and maximum number of pixels in width. Many of the latest LCD's are 2k + pixels in width. With 100dpi and higher pitch, its getting to the point where the LCD display is as good as the first laser printers.
I foresee a problem. It is now possible to create a display system, using xinerama with more display pixels than the X server can address. Say, 16 heads, each with a 2K+ display and you have more than 32k pixels. Many of the newer graphics boards will support 2 heads, and do it at the 2K+ resolution.
A few years ago we (Xorg) talked about this, but at the time it seemed... distant. Not so any more. It is now time to start serious work on extending the X wire protocol so that it can handle very large format video walls and the like, using the newest displays.
Xorg is considering removing the 16 head limit on the server and going to 256. Machines that can handle that amount of PCI buss and card slots etc. do exist now. So, we are pushing the limits from both directions.
