Aug 2011 ~ Double Feature ~ John Miner & Grant Fritchey


Presenter: John Miner of Sensata Technologies
Topic: Working with bit patterns


In today’s manufacturing environment, production lines are automated with robotics and sensors. Many of these low end microprocessors and/or integrated circuits are designed for specific tasks such as temperature and pressure control.

This presentation will review how to store the memory buffer in a table and use a view to interpret the results.

The following topics will be presented with examples.

1. Using the VARBINARY data type to store the bit pattern.
2. Storing a version number just in-case the decode changes.
3. Breaking the pattern into registers and nibbles.
4. Left shifting of the bits.
5. Right shifting of the bits.
6. Combining bits from two registers.
7. Putting it all together with a view.

Managing your data well can lead to savings in disk space as much as 75%.

Topic: Seven Different Solutions for Bad Parameter Sniffing


Parameter sniffing is a misunderstood issue on SQL Server. Most of the time parameter sniffing is helping performance on your servers. But sometimes, circumstances change and what was helping you is now hurting you, bad.

In this session we’ll gain an understanding of what exactly parameter sniffing is and why it’s usually so helpful. Then, we’ll explore how parameter sniffing can go wrong and I’ll show you seven different ways you can deal with it when it does.

You’ll bring back a wealth of knowledge so that you can identify and resolve bad parameter sniffing in your own environment. Everyone has heard about twitter, facebook and linkedin but how or why does one get started?
