Two years ago we have ventured into mathematical foundation of relational theory. From algebraic geometry perspective relations were viewed as Finite Varieties. In the followup exposition we were able to describe functional dependencies via explicit analytic formulas and provide intuitive interpretation of Heath’s theorem.
During the holidays, I check salaries for my students and the IT industry overall. I’m never surprised by the reality, after all salaries pay for return on skills and effort. Here’s my annual look, which some may find unkind but reality is seldom kind.

I posted earlier in the year how to configure a Fedora instance to test PHP code on a local VM. However, I’ve got a few questions on how to find those posts. Here’s a consolidation with links on those steps:

It turned out not to be quite the same, but similar. Analytic functions definitely could help. I'll show how in two parts. First this blog post will calculate the fuel consumption in quantity, then part two will calculate the value by FIFO.
On the last day of the DOAG conference, in the last time slot Patrick Wolf from the APEX development team did a session on the next release of APEX. For the developer the most significant change in the Page Designer is the component view. This will be a tab in the center pane instead of a completely separate page.
I’m not much for non-technical posts, but @ThatJeffSmith told me I needed to blog more often and he has broad shoulders. Besides, OpenWorld was pretty good this year. Martin Widlake already blogged about how the user community makes OpenWorld a good experience. I second that, especially since I had the advantage over Martin of not […]

Last time I went to OpenWorld was 2008, so I'm looking forward to a re-visit and see how much bigger it has become :-)Like everybody else I've been making a schedule for the week.
