All of my previous presentations have to this point been at conferences that are primarily targeted at the PHP coders of the world. As a member of that community, I have always felt comfortable there – talking to and with PHP coders.

This however, seems to be a different kettle of fish.

This Oracle conference seems to be rather large (5000+ according to the site) with lots of content on many different subject areas. I am not sure if that is a good or bad thing, but I definitely intend to cruise through the various tracks and sit in on sessions that I normally do not have exposure to (BI/Data Warehousing, Master Data Management, and Professional Development).

That being said, I wish it was possible for me to also be attending the MySQL User Conference. It is being held the same week as Collaborate in Santa Clara, California. I will miss catching up with many of my good friends as they attend the user conference while I am at Collaborate. But I know that there is always next year.

Day 1:
- Documents, documents, documents by Matthew Weier O’Phinney. I particularly enjoyed that this was focused on the software architectural design and was system agnostic for the document database.
- Technical Debt by Elizabeth Naramore. Her no nonsense discussion and interaction with the audience kept this discussion interesting and engaging. The ideas and concepts discussed were something that every developer and manager should understand.
- Demystifying PostgreSQL by Asher Snyder. I have been wanting to look at PostgreSQL for years, I just never seem to have the time to do it. This was a nice intro to the system and its capabilities which I have to admit, are pretty dang cool.

Day 2:
- EXPLAIN – yeah it was my own talk, but hey – I was there!
- Pragmatic Guide to Git by Travis Swicegood Travis is a gifted speaker that manages to draw you in with his enthusiasm. His clear logical walk through of the basics of Git covers all the commands that a beginner will need.
- Infobright DB by Jeff Kibler This was a talk that I originally went to mostly out of curiosity. Once they started I found myself highly interested (data warehousing and mining is an interest of mine) not just for what they did – but how they did it.
- Welcome to the Dark Side: We have Brownies by Josh Holmes. The talk was informative, engaging, and just all around fun. Turns out Microsoft isn’t so bad after all… I mean – they had brownies even

Day 3:
Umm – slept late and then just practiced my last talk… Since it was on the last set of talks on the last day..

Missed a number of keynotes – did some volunteer work manning the PHP Community booth, but really enjoyed the “Dries” and “ROI” ones.

The various parties/after-parties (official and otherwise) were awesome with more then a few hangovers showing up the next day.

And as a minor side note – I also really enjoyed the Running MySQL at Scale tech talk at Facebook while I was there. Learned quite a bit and also got to see Domas again. I missed his brand of craziness.

I am currently planning to attend the Tampa Barcamp on the Dev day (Sept 26th) with my good friend Davey Shafik. And like a good camper (think that is the term they use), I have a few MySQL talks ready to present if the crowd wants/picks them for the schedule. I am both excited and happy to finally be able to lose my complete n00b status and be able to say I have been to a barcamp!

I look forward to seeing everyone there!

The conference started out with the typical day 0 – Tutorials Day. I only attended the MongoDB talk mostly to learn a bit about it. Kristina was a wonderful speaker who really knew her stuff. And as a MySQL geek, I have to admit that it was interesting seeing seeing my world (RDBMS world) from a different perspective. I even managed not to say a single thing throughout the entire talk though there were a couple of times the others I was with had fun laughing at me holding back.

The first actual day of the conference started out with Josh Holmes keynote on The Lost Art of Simplicity. It was a fabulous talk that forced me to find myself on the wrong side more then once.

From there I went to Eli White’s talk on Anti-Spam and Anti-Gaming. The talk again was extremely interesting and some of his ideas would never of occurred to me. Good thing we have Eli to teach me.

On to Joel Perras’s talk on Graphs, Edges, and Nodes. Again a fabulous talk, that I have to admit – lost me a bit. But it is something I definitely want to learn more about.

From there to Large Scale Systems with David Strauss. This was one of the best talks I will be in at the conference. Learned lots – most of which I did not know enough to ask about… but I do now.

After that I kinda got into practicing for my own presentations and missed a lot in the actual sessions, but still enjoyed the hallway track. I must admit that it has been quite a while since I attended that many sessions at a conference, and all of them top notch talks.

As for my own talks, I thought they went well and seem to be well received. You can find the slides for my talks on my Presentations page.

So to wrap up I had a fabulous time at the conference, learning lots and hopefully teaching others stuff they did not know. I can’t wait for next years.

So off I go – totally clueless and completely unprepared since I figure – hey I’m just an attendee. And yes – I go from bad to worse.

So off to UNF I go. AFAIK SQL Saturday is going to be held in the College of Computing & Engineering – hey my old alma mater – cool! Never mind that it has been 8 years since I was on campus, I know my way around right?! Wrong

I got completely lost since almost all the old parking lots are gone and the ones that are still there are designated parking only… and did I mention that the event is in building 50? Yeah – well, that building wasn’t around when I attended UNF so I then proceeded to get confused because it was a different building then the one I attended. All told I spent about 15-20 minutes being lost and befuddled. Should have given me a clue what an idiot I was being.

I eventually find my way there, check in and grab a free donut and coffee (Dunkin’ donuts – Mmm). The place is just starting to get busy so I kinda meander around watching. I have to admit that in new situations I like to people watch.

First thing I noticed was that this crowd while similar to a crowd I would see at an open source conference – was also distinctly different. The crowd seemed to be older (more my own age rather then younger then me) with a *lot* more women attending then I expected (easily twice to maybe 3 times as many women around then I would see at an OS conference) and very few people had a laptop with them. It kinda threw me there – in a rather good way.

I hang out a bit outside and chat a bit with various people. Once they find out I work for MySQL/Oracle, I of course get the requisite “Dark Side” joke and I try to refrain from commenting that “we have cookies”.

I eventually make my way to my first session – SQL University 101: Starting the SQL Journey I have to say it – it was a great session. It provided a nice intro into the SQL Server world that was both intro and technical enough to keep me occupied for the whole class… I even won a poster for knowing what SQL stood for.

Next I attended the T-SQL 102: Aliases and Table Joins talk figuring it would cover anything interesting on how SQL Server handles JOINs (indexing techniques, what kind of index it uses, optimization techniques, etc.). Well it turns out it was more like a basic intro to writing SQL JOINs so not that interesting for me. What I did find humorous when I first noticed it was that the instructor used Venn Diagrams to explain JOINs… which is something I have posted on in the past.

Now at the time of my Venn diagram post, AFAIK I was the only one who thought of them that way. (Turns out I am not – the instructor stated they first came across the idea back in 2000.) I (being the arrogant POS that I am) wondered if the instructor had somehow come across that information and was using it in their presentation. (Have I mentioned I am a complete idiot most days.) I tried to speak with the instructor for a brief while on the subject and ended up making a total and complete fool of myself with them (someone write a big “L” on my forehead).

So I officially would like to 1) apologize to the instructor for giggling in their class. I am an idiot. 2) apologize for just being an arrogant sh*t. I really do try and keep that under control. I am sorry and I have no excuse.

After that I took a walk around campus for a while. As I said it has been 8 years since I was on campus and so much had changed. I actually was lost until I finally got my bearings finding old landmarks. It was nice being back.

So during lunch I sat in on a couple of mini-sessions. One on becoming a DBA and the other on networking at technical events. Both were very good covering areas that to me are similar in the open source world. One thing I did find interesting is that neither of the instructors discussed participation in open source projects – even if it is on CodePlex – Microsoft’s open source portal.

I am unsure if it is simply not a known conduit for the SQL Server community, or if the culture of the community does not push it the way that, obviously, the open source community would. That would be an interesting discussion to have one day.

The final session I attended was the Introduction to Data Warehousing talk. Again it was a very good talk that covered general concepts as well as SQL Server specific tools. I particularly enjoyed the discussion on design of a data warehouse and the general patterns of them – star and snowflake. The examples given and discussed were easy to understand and follow even though the terminology I am most familiar with was slightly different.

Relatively soon after the end of that session I left to go home and be with the family (it was the day before Mother’s Day after all).

I had a fabulous time at SQL Saturday and if I had a complaint about anything it would have to be the network (of course). Because I have Skype on my machine I was quarantined/locked out of the network a number of times so my connection was intermittent at best.

Now that I have had a chance to see the SQL Server community I have to admit I plan to try and get to a Jacksonville SQL Server User Group meeting some time in the near future if I can. It is always nice to learn new stuff about databases… Don’t get me wrong – I love my RDBMS and plan to stay here a long time but being “the n00b” and adding more tools to my toolbox is not a bad place to be.

The conference this year will be held from May 18-21 at the Sheraton Gateway Suites O’Hare (same as the past couple of years). If you have already been to the conference, you already know about playing Tek frogger – and if you don’t or this is your first conference – be sure to find me at the conference so we can discuss it as we sit and have a drink at “Shirtless Slim’s”.

For those that are interested I will be giving 2 talks on MySQL this year. One will be an introduction to MySQL replication and the other will go over the new features found in MySQL 5.5. Both are new talks for me, so I am rather excited about speaking on the subjects and would love feedback.

I hope to see you there!

1. instructions I used – http://dev.mysql.com/doc/refman/5.0/en/installing-binary.html
2. to create a group in 10.5 – use dscl. In my case ‘dscl . -create /groups/mysql’
3. to create a user in 10.5 – again use dscl. ‘dscl .-create /Users/mysql’
4. I had to make /usr/local with mkdir -m 775
5. I did not have to decompress things since the Mac did it for me – but I did have to place it in my Library dir and make the ln to it in my /usr/local dir
6. DO NOT FORGET to give your root user a password and either drop the anonymous user or put a password on it!

Other notables (yes I am a server noob):

• start the deamon with ‘sudo bin/mysqld_safe –user=mysql &’
• If you forget the ampersand at the end – use cntl+z to escape then use ‘bg’ to put the deamon in the background
• stop the deamon with ‘bin/mysqladmin -u root shutdown’

Other notes to self on having multiple versions available:

1. option 1 – have multiple binary installs in their own folders and just change the ln.. or have multiple ln with individual names. since I do not need to have all of them running at one time – I can start and stop the deamons as I need.
2. option 2 – is provided in the manual at http://dev.mysql.com/doc/refman/5.0/en/multiple-servers.html

So to everyone who kept telling me I would get the job when I swore there was no way (you know who you are) – feel free to tell me “I told you so” next time we talk – and first beer is on me when we meet.
