The Bit Bucket

OT: Green Science and Bogus Mathematics

With the climate summit in Copenhagen now finished, I wanted to make a few comments about a trend that really annoys me. I’m fairly “green oriented” in my outlook but amongst “green” scientists and advocates, there is an endless desire to make each cause sound much stronger than the facts permit. I think this does their support more harm than good. The recent expose on modified emails bore that out only too well but I want to show a few simpler examples.

Odd that you can't create a filtered index on a deterministic persisted calculated column

On a client site the other day, I came across a situation (unfortunately too common) where a column in a table was being used for two purposes. It could either hold an integer value or a string. Only about 100 rows out of many millions had the integer value. Some of the client code needed to calculate the maximum value when it was an integer. First step I tried was to add a persisted calculated column like so:

Should IT Professionals Refuse to Implement Scams (and MYOBFail)

Not long back, it became very common for dodgy domain registration companies to send letters to domain owners that they weren’t dealing with. Rather than saying “hey we’re a great registrar and here’s why you should switch to us”, the common ploy was to send out something that looked like a renewal notice, hoping that the receiver would just authorize and pay it without thinking. In Australia, the ACCC (basically the consumer watchdog) has been chasing down and taking action against such practices.

SQL Down Under show 45 - Jamie Thomson - SQL Server Integration Services (SSIS)

Sorry that shows have been slow coming this year. That’s about to change (famous last words).

The good news is that show 45 with guest SQL Server MVP Jamie Thomson discussing SQL Server Integration Services (SSIS) is now available for download from http://www.sqldownunder.com . In the show, Jamie discusses lessons he learned while moving from DTS to SSIS and covers off many best practices for working with SSIS.

Enjoy!

Book: SQL Server MVP Deep Dives - Launch at PASS Summit USA

This is no ordinary book. Paul Nielsen took up Bill Gates’ challenge at a recent MVP summit to do something notable to give back to the community. He organised a large group of SQL Server MVPs to create a unique book and worked with Manning to get it published. The money made on the book was to go directly to a charity and the charity chosen was WarChild.

I had the privilege (along with Kalen Delaney, Adam Machanic, Kimberley Tripp and Paul Randall) to be one of the editors on this book but the magic contribution has come from the 53 SQL Server MVPs involved with the book.

OT Book: On the Origin of Species - Charles Darwin

Given my interest in science, I’m ashamed to say that I’ve only just got around to reading Charles Darwin’s “On the Origin of Species by Means of Natural Selection or the Preservation of Favored Races in the Struggle for Life”. What prompted me to read it this time was watching two episodes of “The Genius of Charles Darwin” while flying across to the U.S. It’s an excellent documentary by Richard Dawkins. Dawkins can see overbearing at times but in this series, he’s measured, accurate and inspiring. In the documentary, he showed one of his most prized possessions: a first edition copy of this book.

Kevin Kline's Travel Meme

Our buddy Kevin Kline has started a travel meme to provide ideas for people travelling to PASS, given many don’t travel very often. He’s after some good solid travel tips. I’m one of the people he called out so here are a few that come to mind immediately:

1. Delays and mishaps occur. If you don’t allow enough time between flight connections, etc. then you are asking for problems, regardless of what the airline says. For example, I *never* allow an international to domestic connection through Los Angeles of less than three hours and prefer four hours. The further you’re travelling from, the more you can get delayed. Airlines will let you book a two hour connection there. Don’t do it. If you’re feeling frustrated with delays, get over it.
