In the upcoming version 2.6, I've added the ability to skip directly to any part of a playing movie by clicking on the timeline with the Wii remote. It was frustrating not to be able to do that in previous versions and made it difficult to watch or fast-forward through long movies.

The way many Flash movie players handle skipping is by inserting metadata into the FLV file that contains a map between seconds in the timeline and file positions for the keyframes, and that's the way Wii Transfer works as well. Unfortunately this requires rewriting the entire FLV file when post-processing movies. (Ian Baird suggested a future optimization would be to store the metadata separately and redo the player to send seconds instead of file offsets to the server.) I was initially using the open source flvtool2.rb to achieve this, but it was extremely slow, so I rewrote it in Objective-C. (Not a port. The Objective-C version was written from scratch and is significantly shorter than the Ruby version in terms of lines of code. It does a little bit less, but it's optimized for exactly what Wii Transfer needs.)

This chart shows the performance improvements when processing a couple large movie files. Measured in seconds, so shorter bars are better.

The other good thing that came out of all this work is that I can now look at a FLV file in a hex editor and not be totally confused. Hex Fiend was one of the best ways to debug what my code was doing when it failed.

iPhone developers have wondered for months how refunds were going to be handled. Although demo and trial versions (if added) will be used by many more customers, refunds to unhappy customers represent an extremely important part of the relationship between developer and customer. I've written before about my philosophy with refunds and customer support, an opinion that is shared pretty universally in the Mac community. Just yesterday I gave a refund to a customer who purchased the software over a year ago, but apparently didn't get around to actually using it recently and found it did not meet his needs.

If there were a proper way for developers to send App Store refunds — because of unmet expectations (app crashes or doesn't work as advertised) or accidental purchases (my son bought this without asking me) — then this issue just goes away. It doesn't matter whether I Am Rich is worth $999 or whether the shopping cart should be an option in iTunes. The core issue is refunds because it fixes several problems at once, and removes Apple's personal judgement about what is good or bad for iPhone users.

Speaking of people who wrote MarsEdit, our sixth episode of Core Intuition is out. Daniel and I spend a good chunk of the show on bug tracking, thoughts on running a software business while preparing for a new baby, staying inspired and getting distracted, and a bunch more. Plus we put out a call for good artists to contact us.

We had a lot of fun with the show and I hope you enjoy listening to it. If you have feedback, send an email or post a comment on Daniel's blog.

Instead of a formal write-up, I wanted to piece together the week from Twitter posts, but that proved tedious enough that I had to write a little app to help me out. I started by adding my own relevant tweets for WWDC week, then threw in a dozen people I follow and selectively picked the tweets that were significant or about events for which I didn't directly post.

So here you go. How I remembered WWDC 2008, in 95 tweets.

This episode feels a bit more content heavy than the previous one. We talked about what it's like to work while traveling, tech books and some thoughts on the 3rd edition of Cocoa Programming by Aaron Hillegass, and then dedicated most of the last half to distributed version control systems such as Git. Even though it is just days before WWDC, we only touched on WWDC indirectly. I expect there will be enough to talk about after next week to fill more than a few shows.

Editing the show continues to be a challenge but it's so rewarding, just being able to slowly craft the episode from the recordings. You tell a little lie every time you tweak the original source audio, but hopefully the end product feels more authentic or at least fresh. It makes me appreciate even more the work Ryan does on The Talk Show. Our goal is to improve the quality each episode until we reach a point we are happy with, so if you have any feedback I'd love to hear it. After WWDC I'm going to invest in some real headphones. I was shocked how different the show sounds between my speakers, cheap headphones, and iPhone.

If you haven't subscribed yet, you can now find the listing on iTunes and get it synced to your iPod or iPhone in just a few clicks. Enjoy!

Daniel's blog post has more on the announcement. He also has comments enabled, so feel free to jump over there and post feedback, unless it's the angry, negative kind of feedback in which case please send a private email to feedback@coreint.org. :-)

Thanks for listening. We'll be doing these regularly so please subscribe in iTunes if you want to catch the next episodes.

I'm pretty happy with how the implementation has worked out. It's build on essentially three background scripts:

• Parsing replies every minute looking for the friend code pattern (1234-1234-1234 for game codes, with dashes or spaces).
• Taking queued users and pulling everyone they are following into the database.
• Generating and caching the RSS feed for recently tweeted friend codes.

The system currently only pulls the first 300 followers, but it's running smoothly enough that I will bump that up to 500 this week. Over 150 people are currently using it, and the database has about 10,000 records to keep track of friends. I feel like it's architected well enough to grow significantly from here, so I may do some casual promotion of the service this week.

If you own a Wii and use Twitter, give it a try. If you have any questions or feature requests, please send me an email or reply on Twitter. Enjoy!

Speed. This is where the Flip shines. It is compact enough to take anywhere, and simple enough that you can take it out of your pocket and start shooting video in seconds. I've already shot way more video than I would with my traditional DV camcorder.

Battery. It runs on two AA batteries. I was able to record a ton of video before replacing them, accumulating 3 GB of files over several weeks. This is unheard of compared to any other still camera or video camera I've owned.

Transfer. The Flip saves as the Xvid flavor of MPEG-4, which is not supported natively by QuickTime. Luckily a quick Perian install later and you can view and edit them in QuickTime Player or any app that supports QuickTime. Just mount the camera and copy them over, or convert to H.264 with something like VisualHub. The Wii Transfer 2.6 beta also supports Xvid to convert and share to your Wii.

Quality. I wanted to do a side-by-side comparison with Motion JPEG used on most digital still cameras, but this isn't a video hardware review site so an in-depth analysis is beyond the scope of what I need or have expertise in. To my eyes it looks pretty good though. Make sure to get the Ultra, not the regular Flip Video which has a lower bitrate.

Complaints. You need to give the power slider and record buttons some real pressure, and on a few occasions I've clicked record only to realize 1 minute later that it didn't start. I understand that the designers didn't want us turning it on or recording unintentionally, but this negates some of the speed advantage mentioned above.

In a nutshell: The Flip isn't for everyone, but at just $140 it's hard to argue with its strengths. I take it everywhere now. One pocket for iPhone, one pocket for Flip.

Here are the best ways to get Wii Transfer:

• Buy a copy! Just $19. Simple checkout with PayPal and you'll get an automatic email within minutes.
• Write a review for a blog or magazine. Email me first and I'll give you a full license, even if it's just your personal blog.
• Become a beta tester. From time to time, I need people to test the latest in-progress features. Free copy if you send any useful feedback on a beta.

Thanks for your support! I hope one of these options appeals to you.

Rather than bicker with my friends who support Obama, I changed my tone to emphasize our shared values and launched a new site: unitetheparty.com. I've been posting there regularly since March, and hope to build a group of like-minded Democrats to write on this topic, as well as a list of supporters who want to see a joint ticket happen.

Thinking about the endgame of the race in this context provides an excellent backdrop for discussing the real issues important to voters. There's still an opportunity to use these campaigns for good: setting the right tone against McCain and bringing awareness of the Democratic agenda to everyone.
