I recently upgraded my bytemark VM to one of their low energy intel atom powered dedicated servers. Because of an AJAX based mapping tool on one of the sites I host, my VM struggled with only 400mb of RAM (mainly because of lots of simultaneous mysql connections under heavy use), but CPU bottlenecks were never an issue. The 2GB of RAM as well as dedicated RAID1 disks (therefore not competing with other servers for disk I/O like with a VM) has made the site perform much better under “pressure”. I’m saying this cautiously as the site hasn’t exactly been slashdotted yet, and I don’t want people to see it as a challenge!
I noticed that IE7 was caching asp content loaded via AJAX. These asp headers seem to solve the issue:-
Response.CacheControl = “no-cache”
Response.AddHeader “Pragma”, “no-cache”
Response.Expires = -1
Netsight have been so busy recently that we haven’t updated our portfolio for a while, but I wanted to mention this site, as it gave us an excuse to experiment with some nice visual features such as scriptaculous effects, flash galleries etc. The site has a plone back end for Content Management, but the front end was built from the ground up, so is a nice example of a “non-ploney” plone-based site. It helps that Architen had some excellent photography to use on the site – all maintained by themselves via plone including image resizing and cropping for the portfolio pages.

The final afternoon and I face the trickiest decision over which session to attend – all three tracks look useful. I wanted to go to Nate Aune’s multimedia and podcasting tutorial, but i’m fairly well up to speed on that already, but it was difficult to decide between the KSS/ Azax and the UI’s 2.0 tutorials. I plumped for KSS on the basis that I have no idea what it is..
I tried out a friends pocket pc (or is it windows mobile now?) smartphone recently – a cool little device with a slide out QWERTY keyboard (I think it was a variation of this htc device). It also had wifi support so I thought I would try to blog from it. However, he hadn’t got opera installed and the wordpress gui completely failed to work in pocket internet explorer. I’m sure there is a solution to this, but I was disappointed that the wordpress online admin didn’t gracefully degrade.
Another abbreviation(?)/buzzword that i’ve been hearing for months but I have only just understood what it is. From All in the Head (Drew Mclellan’s blog):-
