Slide Deck and Recording from todays webcast

For those that weren’t able to join the presentation, I’m posting the slide deck and a recording of the presentation.

The slide deck only has a couple of slides in it, so my it self it isn’t all that interesting.  The recording has taken via Net Meeting.  It’s the first time I’ve recorded something via Net Meeting directly, so if it isn’t great sorry.  I’ll try better next time.

The recording works in IE, I don’t think Firefox likes the format.

No, I will not do your homework for you

If you are a computer science major, or taking a computer class of some sort, then by all means use the Internet for research.  That’s what it’s there for.  If you’ve written some code and it’s just not working correctly then by app means post your question on a forum (with the code) and ask what you are doing wrong.  Someone will be more than happy to point you in the right direction.

It takes a big man to admit when you’re wrong.

It’s been pointed out to me just how screwed up yesterdays post was.  I’m a big boy, I can admin it when I muck something up, especially something that badly.

Sorry about that, apparently I needed a lot more sleep (or a lot more coffee) when I wrote that post.  I’ve corrected yesterday’s post so that it’s actually accurate now.

Understanding what the WITH ROLLBACK IMMEDIATE does

Based on some questions on forums and some of the responses that people have been giving there appears to be done misunderstanding about what the WITH ROLLBACK IMMEDIATE option does when added to the ALTER DATABASE command.  My goal here is to try and clear up at least some of the confusion.

DENY overwrites GRANT, most of the time

SQL Server rights are pretty easy to work with most of the time.  You grant a bunch of rights to an object, then you deny rights to those objects and the user looses the rights.  Pretty easy.  Now the catch is that if you use the fixed database roles, those roles overwrite any denies that are in place.

Dates can easily be the hardest datatype to work with.

The datetime data type can be one of the hardest to work with when it comes to index optimization.  Most queries that use a datetime data type for filtering (part of the where clause) only want to match the date portion of the value.  Most people handle this via a convert function around the date column.  This causes the index that you create to become useless as the convert function causes the index to be scanned not seeked.

My experiences upgrading ESX 3.5 to vSphere 4.0

A couple of weeks back I begun the process of upgrading our VMware ESX 3.5 systems to vSphere 4.0.  I’ve got to tell you, that has to be the easiest system upgrade process in history. Continued »
