Isn't She Beautiful?
What can I say? I just have to share this wonderful photo of a smiling Loey Lucille....

The PL/SQL Whisperer
That is my new nickname, after my latest round of trainings in Europe.
I spent two days in Berlin, training 25 developers at an event sponsored by DOAG. Then I headed over to the Netherlands to spend a couple of days with 37 developers at an AMIS-sponsored training.
But on Tuesday, after I completed the first day of training without the assistance of a microphone, my voice said "Bye, bye!". I woke up Wednesday morning to discover I had lost the ability to speak above a whisper. DOAG hustled, did what was necessary, and brought in a portable microphone/speaker system. AMIS made certain to have the same ready to go on Thursday.
And so for three straight days, I whispered about new features of PL/SQL in 11g and much more besides. The attendees were very good natured about this less than optimal situation. One person said it made the whole class more exciting - it was as though I was giving away secrets, that no one should hear- except for the very special people in attendance.
Several students in the Dutch class even found themselves whispering to me when they asked a question - whispering, it turns out, is socially contagious! And I was quickly anointed the "PL/SQL Whisperer." Well, I can think of worse names, but I sure hope that soon I will recover my voice.
This was only my fourth business trip all year, which is a truly wonderful change from previous years (a less than fantastic result is that I will lose my Platinum status on American Airlines next week, so it will be tough to even get exit row seats when I do fly).
It was, unfortunately, a bit of a hard week on the road. Besides losing my voice, my flight on Wednesday from Berlin to Amsterdam was cancelled. I had to reroute through Zurich, but the flight to Zurich left late, so while I was able to just make the connection to Amsterdam, my bag did not follow along with me. By the end of the first day of training at AMIS offices, I had quite the five o'clock shadow. But the bag was delivered on Thursday, so it wasn't really such a big deal.
And then on Friday, I celebrated the end of a long week with a night in Amsterdam. Had a nice dinner with good friend, newly-minted Oracle ACE, AMIS consultant and father of three wonderful children, Patrick Barel. Then I went back to my hotel room to catch up on email and call my wife via Skype.
But the wireless network was not available. So the manager dutifully visited my room with an ethernet cable and (as far as I could tell) had to jam the cable a bit forcefully both into the wall and into my laptop. That made me uncomfortable. And still no Internet access.
So then he agreed to let me use the Internet in a different room - which led to a very irritating discovery: the ethernet plug would not come out of the back of the laptop. The spring that holds the cable in place had snapped. Manager Jon poked at it for a while, making me more uncomfortable, but it would not come out. Oh, I was very bummed and finally gave up, had him cut the cable so I could take the darn thing home, and figured I would have to have a technician get it out.
Yuch.
But then the day manager visited in the morning before I left for the airport. He had better tools and was able to quickly remove the plug. Whew, what a relief.
Both classes went well (of course, the students might feel differently, I suppose) - the PL/SQL community in Germany and the Netherlands is wide and deep: lots of very experienced developers attended. So I learned a few things along the way, which will soon make themselves known in PL/SQL Challenge quizzes.
I also made an interesting discovery about how students concentrate on and extra information from the hundreds of slides and hours of talking I give them to them in a two day class. I covered FORALL in the class, also its SAVE EXCEPTIONS clause. I showed slides, ran code and talked about how if at least one statement raises an error, Oracle will save the exception information and then raise the ORA-24381 error. I talked about how you should avoid writing an exception handler like:
you can write an exception handler like:
In the AMIS class, we ended with a short quiz. Two players tied for highest score (they selected 19 of 21 choices correctly across 5 questions - quite good!). So it was necessary for these two hotshots to engage in a sudden-death tiebreaker. The way I do this is I show a slide with a question and the first person to answer correctly wins.
The first slide asked: "Which feature of PL/SQL does this number relate to?" And then I showed "-24381". I thought there would be an instant response, given how often I showed and mention this number in the class.
And I was shocked to discover that neither of the students recognized the error code. I stared at them, surprised. Really? When I talked about it, referenced it multiple times, in the last two days?
Well, OK. We went on through several questions without success and then Christian Rokitta identified correctly that the optimizing compiler was first introduced in Oracle Database 10g. So congratulations to Christian for his first place showing, and to Danny Ven for the other score of 19 and his second place.
I am not exactly sure what to conclude from the inability to recognize the -24381 code. Perhaps students in my courses are confronted with so much information that they automatically filter out low level details. That way, they will be able to concentrate on the bigger picture.Certainly, people usually do not complain about how little I cover in my classes or how slowly I go through the material. And right at the beginning, I tell them to focus on principles and concepts, don't worry about all the technical details.
So I guess they took my advice!
In any case, now it is 4 AM on Sunday and I am (a) back in Chicago (hurray!) and (b) awake due to jet lag and (c) still without a voice and (d) most sadly, without a PL/SQL Challenge website. For some reason, it is unavailable but hopefully that will be fixed really soon.

Gingrich the Man - When the bar is set very low
Here's what Newt Gingrich says about himself:
"I don't claim to be the perfect candidate. I just claim to be a lot more conservative than Mitt Romney and a lot more electable than anyone else."
Wow, now that's truly inspiring, Newt. Not.
Mostly it just tells you how terrible the field of Republican candidates for President are, for 2012 - with Gingrich himself admitting it.
Isn't it strange that in a nation with the power and prestige of the United States, in a nation with just two parties competing for power, that the Republicans are left to choose between the likes of Bachman, Santorum, Gingrich, Paul, Cain, Romney and Huntsman?
Of course, Huntsman seems lots more human, rational and sane than the others (except for the Mormon part, to which "rational" surely does not apply - as it does not apply to Catholicism, Judaism, Islam, etc. - by definition). But he doesn't stand a chance.
