WWDC Attendee Guide
Jun 4th
Last year was my first time attending WWDC and I can easily say that it was one of the most enjoyable weeks of my life. My geek squee didn’t shut off from the moment I left SYR until about 3 months after I returned.
I’ve been meaning to put together an attendee guide since I got back, so I figured what better time than two days before I leave for WWDC again this year.
- Pack jeans, t-shirts, and hoodies/sweatshirts/long sleeve shirts. San Francisco is not warm. It was typically between 50º and 65º the entire week last year.
- Stand in line for the keynote. I had a great time standing in line with people I had only known online and who have become good friends.
- Meet people. Many of us geeks are shy and that’s OK, but do yourself a favor and try to break out of your comfort zone and say hi to someone you don’t know. Easy conversation starters include, “Where are you from?”, “What have you worked on?”, and “Wanna see my Steve Jobs tattoo?”
- Find a group to hang out with. I had a really great group of folks that I stuck with for most of the conference last year and it made it a much more enjoyable experience. Go to parties with them, sit with them in sessions, but don’t be exclusive. Remember to say hi to other folks too.
- Go to the sessions. Plan ahead of time by looking at the session list and see which ones interest you and try to hit all of them. There is some amazing information presented in these sessions so soak it all up. The videos that are made available after the fact are great, but only cover about 50% of what you will get by actually sitting through it.
- When you sit down in each session plug your laptop into a power strip and plug your iPhone into your laptop. Yes, even if it doesn’t need it. With the amount of tweeting and texting you will be doing you will be testing the limits of your iPhone battery every single day. NEVER waste an opportunity to charge it.
- Stay hydrated. Drink lots of lots of water to help keep your energy up. If you do this one simple thing you will not tire out the entire week.
- Charge your laptop and iPhone over night every night. It gives you a good jump on the day.
- Use the labs. The labs are basically free DTS incidents where you get to sit face-to-face with the Apple engineers that wrote the code that you are using to create amazing things. Ask them to help you work out an issue that you’ve hit. If you haven’t already done so, start a list of WWDC Lab Questions so that you’re prepared. If you aren’t working on anything or don’t have questions of your own, see if a friend (or a new friend) would mind if you tag along to their lab session. You will learn something.
- Eat the free lunch. I had heard horror stories about the lunches at WWDC, but to be perfectly honest they were pretty good. Sit with folks you don’t know, strike up a conversation, and enjoy the free food. Even if you think the meal sucks, chances are the conversation won’t.
- Go to the bars and go to the parties. Do not go back to your hotel room for more than 15 minutes after the conference ends for the day. Get changed (if needed), take a few minutes to stretch out on the bed and relax, then get your sneakers on and get back out the door. (see #3 above). Even if you are not normally a barfly or even if you don’t drink at all, get out there with a Pepsi in your hand and talk to people.
- Do not get hammered every night. Enjoy the company with a drink or two, but don’t get blitzed. You want to be on your game for the full day of sessions the next day and you don’t want to waste a day puking and avoiding solid foods.
- Use Twitter. Do a standing search for the #wwdc hashtag and get to the good parties and bars.
- Nervous about talking to some of the rockstars in the Mac and iPhone programming world? Buy them a drink and don’t be shy about it. I have yet to see anyone decline free booze at WWDC.
- Bring and handout business cards. Or anything that has your name and info on it. Something that helps me remember who you are. Yes, say what you want about handing out pieces of dead trees and I will no doubt agree with you, but to be perfectly honest the only people that I really remember from WWDC last year are the people with whom I exchanged business cards. When you get back to your hotel for the evening make a note on the cards you received to help you remember something about the person.
- Email the people that you met when you arrive back home. When I got back to SYR I sent out a mass email to everyone whose email address I had acquired just to say “hi” and tell them that I had a great time meeting them. I’ve also emailed this same group a few times during the year just to drop them a line and let them know what I’m working on. It’s a good way to keep in touch.
This is by no means an exhaustive list, but these are the things that really stick out to me from last year. Enjoy and I hope to see you there!
The Awesomeness That Is Bodega
Jan 17th
Let’s get one thing out of the way first thing: I’m a big fan of Bodega and have been since I heard about it firsthand from the guys at centrix.ca during WWDC 2009.
Bodega is a free Mac application that helps you discover and download Mac applications. It is built in the spirit of great software sites like MacUpdate, but takes the experience and puts a great looking Cocoa wrapper around it. Make no mistake, this project is a big undertaking with a lot of moving parts and a lot of coordination between those parts. Yet with steady progress and determination these guys are really crafting something cool.
The impetus for this particular blog post is to gush about what I think is Bodega’s killer feature: keeping track of and installing updates for the applications installed on your computer. I really like Andy Matuschack’s Sparkle framework, but one of the necessary evils of that framework is that it doesn’t notify you that there is an update for a particular app until you run that app. When I launch an application it is done with the intention of performing a task immediately, but if there’s an update for that particular app I am yanked out of my workflow to deal with the question of updating the app first. Yes, I can continue to work, but in the back of my mind I’m thinking about how I don’t have the latest version of the software that I am currently using, and it bugs me.
Enter Bodega. Once every few weeks I will launch Bodega and click on the Applications section in its sidebar which presents me with a list of all the software currently installed on my system*. The killer feature is that Bodega scans all of the Sparkle feeds in these apps and will tell me if there’s an update for any of them. With two clicks (one to download and one to install) I can download and install any of the updates that I want. This simple process greatly reduces the chance that the next time I launch an app I will be presented with the option to download and install an update, Bodega has already taken care of it for me.
If you haven’t downloaded Bodega yet I highly recommend that you do and take it for a spin. If you’re a developer and you haven’t submitted your software to Bodega, I highly recommend that you do that too.
* Bodega is opt-in for developers, so if a developer hasn’t submitted their software to the Bodega site it won’t know about that software on your computer.
Quick and Easy Drawing Performance Debugging with NSShowAllDrawing
Jul 10th
While watching one of the WWDC09 session videos I was informed of a great tip that I had been previously unknown to me: Pass -NSShowAllDrawing YES as an argument to your application in Xcode to see a visual representation of the drawing that your application performs as it runs.
To illustrate how NSShowAllDrawing works and the issues it can help you correct I’ve put together two videos. The first shows my app, Bezipped, in its current 1.0 state and its current drawing behavior.
This second video shows how I improved the drawing in Bezipped simply by setting the top-level container to be backed by a Core Animation layer:
I highly recommend giving your app a spin with NSShowAllDrawing if you haven’t already, it was certainly a real eye-opener for me. There are some additional resources for debugging your drawing performance on OS X (as pointed out to me by André Pang) provided by Apple here: Drawing Performance Guidelines: Measuring Drawing Performance
Lastly, both Alan Rogers and Steve Streza pointed me towards Quartz Debug.app (included with the developer tools) as another means to see similar redrawing behavior. I found Quartz Debug’s options to be a bit heavy-handed as the drawing performance of the entire OS was shown instead of just my app, but your mileage may vary.
WWDC09 Sessions & Labs
Apr 7th
Apple has posted the first set of scheduled sessions and labs for this year’s WWDC here: Worldwide Developers Conference 2009 – Sessions & Labs.
Off the top of my head I think I will be keeping an eye on:
- Advanced Debugging
- Cocoa Tips and Tricks
- Concurrent Programming in Cocoa
- Effective iPhone App Architecture
- Embedding Maps in iPhone Applications
- Performance Tuning with Shark on Mac and iPhone
- User Interface Design for iPhone Apps
Which ones do you have your eyes on?
WWDC09
Apr 4th
I am happy to report that I will be attending WWDC this year! It will be my first time at the conference and I couldn’t be more excited.
I’m looking forward to “drinking from the fire hose of knowledge”, meeting all the great developers that I look up to, having drinks with friends that I’ve only met online, and soaking up as much knowledge as humanly possible in a 5-day period.
If you’re also going to be out there feel free to drop me a line on twitter or leave a comment below!
