Hotsos Symposium 2009 Call for Papers

The Call for Papers for Hotsos Symposium 2009 is now open. To submit an abstract proposal for the event, please visit the Call for Papers page. The call will remain open until 24 October. This is your chance to get your name on the agenda and earn a complimentary pass to the event.

I love the Symposium for the people who show up, both the speakers and the attendees. If you've been there, you know: it is the best event of the year for professionals interested in Oracle performance. It's one of the rare places that I can just sit down with a pencil and fill my notebook with answers to long-standing questions and good new ideas to pursue for the coming year.

We've already booked Jonathan Lewis for two technical sessions and the Training Day event, and Tanel Põder has confirmed his participation on the agenda as well. That makes two of my favorites, with lots more on the way.

You're probably aware that earlier this year, I left Hotsos with a few former employees to create Method R Corporation (see our press release for more info). Method R and Hotsos are pleased to continue the tradition of the Hotsos Symposium as a joint venture between our two companies. I hope you'll join us.

Messed-Up App of the Day

My family has a cat. I don't like to talk about it, because I really don't like cats that much.

One thing our cat does that's kind of interesting to me, is that she brings "gifts" into our garage near her food bowl. Here's a picture of one. She climbs to the tops of the trees in our yard to catch these things.

Jeff Holt does something similar on occasion. Sometimes when I return from a trip, there'll be something on my desk from Jeff for me. Today, it was this:

It's a piece of wire taped to a sheet of paper. And that's my Messed-Up App of the Day.

Handwritten on the paper is this message from Jeff:
This was a grounding cable for the network.

The first few seconds I looked at the cable, it didn't seem that funny to me. It was about the same reaction as when I see a dead cicada next to the food bowl at home. Amused. But not "LMAO."

Sometimes, what Jeff thinks is funny is funny because of something I haven't learned yet. So I got thinking, maybe his point is that it's against code to use stranded copper wire as grounding cable. Most of the ground wire you'll find in houses is solid copper. But then again, no, stranded cable is fine for ground wire. If I remember correctly, you use stranded instead of solid wire in applications where the wire is going to be required to flex in normal operational circumstances.

Then I noticed there was red tape on one end of the wire, and black tape on the other. Ah, ok, that's what was funny--ground wires are supposed to be labeled green. I figured the guys who wired our network probably just used some scrap wire instead of properly marked "ground wire." Sometimes that kind of thing bugs Jeff, and he knows it bugs me, too. Mystery solved, then.

But not really "LMAO," though, when you think about it.

Then I picked up the wire and looked at it. Look at this:

Oh... It's not tape. That's two wires. One red, one black.

Ok, that's legitimately "LMAO."

P.S.: If you have trouble explaining to your friends why this is funny, the following handy diagram may help you.
