After arriving at JFK, taking a taxi to the hotel and checking in, I just tried to stay awake for a while. Then Adam called and said "we're going to dinner at a great place in Little Italy..."
We all met downstairs and hopped a ride to our food (and many glasses of wine). Angelo's was busy. The bottom line: best Italian food ever! If you're ever in the area, I highly recommend it. It's amazing.
After that, we wandered over to a cafe for dessert. Damned good stuff. Can't remember the name of the place.
Oops. With the 80's music playing on the iPod, I finally motivated myself to write my talk for the conference. I still have 2.5 hour of flying to go, so it's not like I'm waiting until the last minute.
The talk seems to be of the right length. But I'm worried about the topic. I know I'm supposed to talk about MySQL & PHP, but what about them am I supposed to say?
I don't remember, exactly. And I don't have a conference program handy. And it's not like there's WiFi in-flight (in a few years maybe?). So I'm guessing. Hopefully I'm close. :-)
Right now, I have the standard preamble, followed by a review of MySQL 3.23, 4.0, 4.1, and 5.0 features and development. I then move on to some performance tips. Then I get into a bit on PHP/MySQL advice (mostly about persistent connections since they're a persistent source of "discussion" among some folks). I finish up with some talk about mysqli, the new MySQL API that has been exposed in PHP for use with MySQL 4.1's binary protocol (prepared statements and all that goodness).
I hope there will be questions during the talk (there are always seem to be) that can help guide things a bit.
I love my iPod. And I really love having power at the seat. Other airlines could learn a lot form American. (I just got the battery warning and plugged in.)
(A few minutes later.) Hmm. It's getting bumpy. Hard to type. We're over the plains now and the atmosphere is a bit more unstable here. The pilot is taking us down to a lower altitude. Hopefully that'll help. Looks like part of Idaho maybe.
(Many minutes later.) Well, we're flying over Lake Michigan now. No turbulence at all, but that's to be expected. Water has a funny way of calming the atmosphere. It's a very clear day. Ya know, I'm only a about 30 minutes of flying time from my home town of Toledo, Ohio.
(A while later.) It looks like there's great soaring over Pennsylvania today. Lots of cumulus clouds popping up. I even spotted some nice clouds streets. Their altitude is difficult to judge, but it seems to be at least 5,000 AGL. From the looks of it, one could have launched at 2:30pm and expected to stay up for several hours without much trouble. Amusingly, a 757 pilot probably looks down there and sees turbulence. Beauty is in the eye of the beholder, I guess.
(Later yet.) Well, we're 80 miles from the airport, landing in about 20 minutes (gate 43. My body really doesn't believe that it's already 4:30pm. Hopefully dinner a good night's sleep will help that. I guess it need to put the notebook to sleep now and re-pack things. At least the battery is fully charged again!
Funny note. The flight attendants can't tell time. They just announced it was 2 minutes until 4. Then 2 minutes until 5. And then someone gave 'em a working watch and he discovered that it is roughly 4:35pm.
Heh. That's all for now. I'm hoping to post all this crap using the WiFi from the conference in a few hours. We'll see. If not, there's always dial-up (shudder!).
Like Jim I'm hoping to spend some time outside while in NY for PHPCon. With the conference hotel so close to Central Park, I'll likely spend some time there with my camera.
I, too, am annoyed by Saturday's weather forecast. Derek, Kasia, and I were gonna maybe do something outside. But Mother Nature may have teamed up with Murphy to thwart that plan.
I read but never got a chance to respond to Scott's question/tip:
Now Feedster makes pretty extensive use of MySQL and as I am reviewing my table structure, something I'm noticing is that I'm using way too large fields all over the place. Now if I read this MySQL man page correctly, I can use a TINYINT to store between -127 and 127. Like a lot of people I suspect, I was just using an INT. That's 4 bytes instead of 1. Not a big savings but if you have this kind of wastage on a number of fields, it adds up.
He goes on to suggest that folks figure out their max values needed for each column and make the right choice. I agree completely. As he suspects, this is something I mention in myMySQL Optimization talk(s) but I tend not to give it a lot of attention. That's often because there are a lot of other (bigger) mistakes that people seem to make.
Anyway, using the most logical column type is smart for two reasons. First, it helps performance. Smaller columns use less space, so more of the data can be cached in memory. It also means fewer disk seeks and that translates to faster disk reads (and writes). Secondly, by using a TINYINT instead of INTEGER, MySQL will limit the size of values you can stick in there. So you're getting a bit more error checking that you don't need to code. I don't think you should rely on it being there, but it's nice to know that it is. Don't write sloppy code.
According to Russell it is:
Every day I'm getting more and more frustrated with email. It's so closed, proprietary, unsearchable, filling with Spam, yet so vital to every day life. It's nice that we're getting close in a lot of ways to replacing it
I'm not sure what he meant by that. Anyone want to enlighten me?
It's gonna be a long time before we replace e-mail. More likely, we'll re-work SMTP to make e-mail more accountable (to combat SPAM, mostly) and to add features that don't exist today. But one to one and one to many store and forward messaging isn't going away.
A flight attendant just got on the PA to ask us to lower our shades "for better viewing of the in-flight movie."
Fuck that.
I'm not watching the crappy in-flight movie. I'm on an early west to east cost flight and depending on my iPod and the abundance of daylight (I got a window seat by choice) to help adjust my sleep schedule. I'd rather not be falling asleep tomorrow morning during the talk I'm giving. If this was a red-eye flight, that'd be one thing. But for most of us, it's either 10:30am or 1:30pm right now.
If the other person in my row asks me to close it, I will. But she looks perfectly content to me.
Why don't they also ask everyone to return their seats to the upright position for the comfort of those using laptops to try and get work done during this 5 hour flight?
Because this isn't a flying office. And it's also not a flying movie theater.
On the other hand, if this is my only complaint so far, things are going well.
If I was Ann Harrison, I'd be pissed too.
Firebird is an Open Source Database, just like PostgreSQL or MySQL. I'd hate to see the Mozilla folks confuse things so much that they have to start calling it FirebirdSQL.
As I write this, we're cruising at 37,000 feet above Utah, just east of the Rocky Mountains. The the flight left on time, I have a window seat with laptop power (not that I need yet, but it'll come in handy), the seat next to me is empty, and it has been a smooth ride so far.
(Of course, as I wrote that the seat belts sign came on. But it didn't last long.)
The Bay Area was covered by some status clouds at roughly 4,000 feet (guess) when we took off. As we flew over the central valley, the clouds vanished. The didn't reappear until we passed Lake Tahoe, on the California/Nevada border. And we flew right over the lake. Quite a beautiful site with the all the snow capped mountains around. Someday I'll have to do some soaring around the Lake Tahoe area.
The whole "more room in coach" on American Airlines proves to be especially helpful when you want to use a laptop without fussing when the person in front of you reclines his seat. And, hey, their breakfast wasn't bad either. French toast and melon. I guess that's my second breakfast of the day. The oatmeal and banana at 4:45am was my first. Yeah, I got up early because I didn't feel like packing last night. I'll just be sure to find something good for dinner after I settle in at the hotel and try to find some of the PHP freaks.
Oh well, time to catch up on a bit of my blog reading. Unfortunately, I can really only catch up on those feeds that provide full content via RSS. My aggregator (SharpReader currently) can download the RSS but doesn't know to fetch the full entry pages too. No big deal. I'll just bust out the iPod and start working on tomorrow's presentation.
