Previously I talked about the importance of historical perspective to server performance tuning, but it applies to many areas of working with databases. For the last part of this mini-series, I thought I’d pull together a few more examples. Execution Plans and Optimiser Statistics I’ve written several blogs recently about the value of keeping a… Continue reading Historical Perspective (Part 3)

Apologies to anyone who is waiting for a reply to an email they’ve sent me, but I’ve been experiencing fairly severe problems with Yahoo mail over the past couple of days. The first signs were a couple of consecutive evenings when my mailbox was constantly busy so I couldn’t retrieve mail. Then no mail arrived… Continue reading Yahoo Mail Problems

I have plenty of blog ideas floating around, but the tatty layout on my website has been bugging me for ages so I’ve made a start on that.

I’d definitely question the accuracy of some of the information on there, but it looks like it’s pretty easy… Continue reading Game Innovations

There are still a few minor (I hope) issues with the blog. RSS Feed 1) Thomas Presslie mentioned that the success of the RSS feed is intermittent – it seems to miss posts or they appear late.
