Weblog entry #51 for Steve
See all weblog entries made by Steve.
Xen 3.0 is now out.
I've installed it upon my laptop and will write up a brief guide shortly, perhaps tomorrow.
In other site-related news I wish to use Ajax, I've heard it is the bees knees!
So far my simple demo works, and I can see a lot of cases where I can use it - sadly not on this site though.
The most obvious place to use it here is to replace the poll with the results once you've voted - but honestly I'm not sure if that is a good idea.
Other uses are harder to think of. Short of comment previews perhaps?
It did occur to me a while back it might be nice to allow users to "rate" articles, on a 1-5 scale. I've seen IBM do that on their developer site, and I do usually take the time to vote.
I'm not too sure of the gain, since i can usually tell by the comments when a piece is good / bad. Perhaps something to code for a rainy day?

That is a nice site.
I guess adding technologoy for the sake of it is a bad plan, but the more I play with simple demos the more I like it!

I'm usually pretty paranoid about checking all kinds of things. But that is certainly something to be aware of so thanks for pointing it out.

I use Xen 2.0.7 on sarge to run various sarge (mainly) hosts at home, and I recently make the switch from an old woody server to a xen-based sarge one at work.
It runs well and I really love XEN (creating a new server for watever in 15 minutes is... so goood), it's the future of virtualization technology, but... do you know what are the differences between Xen 2.0 and 3.0?, I checked on google and Xen sites, but can't find anything.
about Ajax, I think preview of comments is a good tidea, but, as you say, not really critical for the site.

Thanks :)
I tried to look at the changlog link on the Xen website, but it doesn't contain anything useful so I'm hazy on the changes. I know that it has got faster, more stable, and is getting better on 64 bit machines but more than that I don't know.
Using it is very simple, and as you say, a new instance can be created very quickly. The only drawback is the requirement of having a special kernel, etc, I liked UML because of its simplicity, but Xen currently has it beat.
