WWDC 08 was incredible. While the iPhone gold rush euphoria contributed, everything just seemed especially good this year.

I’ve been quietly disappointed in Leopard since it shipped. It just seemed too rough around the edges and somewhat rushed, especially compared to the polish demonstrated by the iPhoneOS. Because of that, I’m probably more excited about Snow Leopard than I was about Leopard. Besides the promise of generally improving the overall experience, the under-the-hood OpenCL and “Grand Central” additions are truly revolutionary advances for desktop OSs. The idea behind OpenCL being able to utilize the largely untapped parallel processing power of the GPU has the potential to radically reorganize the entire idea of computing, moving things distinctly towards a brain-like collection of specialized processing units. I’ve been joking this is OS X SP1 but that’s just not true, Apple is mainlining some serious innovation into the backend of Snow Leopard and this should be a very, very good release.

My plan for this year worked very well. I managed to set aside the week prior to essentially cram on Cocoa and Objective-C. While that was originally supposed to be three weeks, the time I eeked out still helped a great deal. I also maintained a very disciplined focus about which sessions I went to. In the past I’ve flitted around trying to get a taste of every subject that interested me — which is almost everything. This year’s deliberate focus and pre-study nearly eliminated the blank-stare drift I’d experienced in the past and left me feeling more confident than ever about building stuff with Cocoa, writing FXPlugs and making things for iPhone.

But far and away the best thing about this year was the people. Twitter made a lot of this possible by starting conversations beforehand. I think I probably met half my twitterstream in person, which was awesome and kind of funny. The social dynamic of first meeting twitterers is sort of one where everyone treats everyone else like a celebrity. It ended up being this wonderful abstracted feeling of recognition which wasn’t nearly as creepy as it sounds like it would be. My only regret is not meeting the handful of people I knew were there but never crossed paths with.

There are just too many people to call out, but I was blown away by just about everyone I met.

Short this year, but I wanted to get something up.

• New iPhone demo
• iPhone not immediately available
• 10.6 demo. No, this isn’t 10.5 SP1 (really!)
• No new MacBook Pro, much as I want one
• A cleaner architectural re-alignment of OS X from a developer perspective
• Twitter will melt
• AAPL will be up at the end of the day

I don’t see how they can launch the store until next week. Half the people here would be immediately flooded with support and administrative requests. There will be pre-launch resources available, but the store won’t launch right away.

10.5 is great, but there are a lot of rough edges. The rumors about 10.6 being previewed are probably true, but I don’t think this will be a $129 upgrade. This will essentially be Service Pack 1. Apple isn’t Adobe, they won’t charge money to fix things that are broken.

Twitter is going to add such a bizarre additional layer to this.

And we’re walking in… or at least closer.

Update: At some point, probably with iTunes 8 though I didn’t notice at the time, iTunes added support for batch changing video format, making the script featured in this post obsolete… as it should be.

Original post follows.

We usually keep our home movies in iPhoto, but recently I’ve started moving some select clips into iTunes. Unfortunately, the list of Movies quickly becomes unmanageable. These kinds of videos are much easier to work with when grouped as TV shows, but unfortunately iTunes won’t batch convert Video Kind.

So I wrote a script. In addition to defining selected movies as a show, it also tags their season with the current year and sets the Show Title. Here’s the script: (Open in Script Editor)

set showTitle to display dialog “Enter TV Show Title” default answer “Family Videos” buttons {“Cancel”, “Ok”} default button 2

set theYear to year of (current date) as integer

tell application “iTunes”

copy selection to tracklist

repeat with theTrack in tracklist

set show of theTrack to text returned of showTitle

set season number of theTrack to theYear

set video kind of theTrack to TV show

end repeat

end tell

To use that, just select some movies in iTunes and run the script. Whatever’s selected will be tagged and grouped under the title you entered.

Now our home movies are all grouped together and easily synced to iPhones or other iTunes fed products like iPods and Apple TVs. To view videos on any of those devices, the movies will need to be converted to iPod compatible format. QuickTime can do it, but iSquint/VisualHub can do it much faster.

This could have been done with AtomicParsley, but AppleScript is easier and pre-installed on every Mac.

What would be really great is if iTunes and iPhoto could talk to one another and pull video content out. iPhoto has supported movies for years now, why can’t they talk to each other? (because neither was designed for handling video formats?)

There’s plenty of room to improve this, if you do please post a link in the comments.

The main iTransmogrify! script has been updated with a bunch of new functionality:

• YouTube.com pages are now supported (see notes)
• Daily Motion videos are supported for new-style urls (see notes)
• Kink.fm player and listings page are now supported
• Sideload.com play links are now supported
• WordPress Blogs using Viper Video QuickTags are supported for YouTube
• All media links now open into new windows, so you won’t have to re-transmogrify a page with several media files after playing one. Note that this is dependent on the iPhone, sometimes it will blank other windows)
• Some content in iframes will now be converted.
• MotionBox, Viddler and Vimeo embedded videos, while not supporting iPod/iPhone alternate content, now link to their respective detail pages.

The main bookmarklet code was updated. This was necessary to workaround a frustrating oversight with Google Code hosting. Everyone will need to update their bookmarklet, in the future all updates will be automatic.

This has turned out to be far bigger than I ever imagined. Thank you to everyone for the links, feedback, compliments and ideas.

Known issues

LiveJournal pages redefine a bunch of core JavaScript functionality, breaking all kinds of stuff including jQuery. Additionally, they’re serving media in an iframe from a different domain, meaning JavaScript couldn’t access the frame even if they hadn’t broken it.

Notes

YouTube Internal pages
Because of a strange iPhone quirk, these links all need to go through the Google redirector, otherwise they bounce back to uk.youtube.com instead of playing.

DailyMotion
DailyMotion videos using new-style urls, which are usually about six digits long, work correctly. Videos using the old-style alphanumeric ID do not work yet. I’m probably just going to resort to building a simple web-service to grab those. Additionally, there is no way to programatically access the mp4 alternate content url, so I just linked to their iPhone pages. I’d prefer embedding QuickTime directly, but it’s just not possible yet.

John Gruber of Daring Fireball (thanks for the link!) knows a lot about font-rendering, however in a recent post discussing screen-rotation and sub-pixel text rendering he let this slip:

“I tested it on my Cinema Display with the screen rotated 90°, and, to my eyes, sub-pixel anti-aliasing still looked good.”

That is just preposterous. Aside from his observation being completely wrong, he also revealed a bug in OS X: The current system doesn’t recognize rotated pixel orientations, sub-pixel rendering on rotated screens should probably be disabled automatically. (rdar://problem/5627732)

Here are two screenshots of my browser’s address bar as displayed on my Cinema Display, which clearly shows the difference. The top image is Leopard’s default sub-pixel rendering. The second image is the same bar photographed with my display rotated 90°, the photo was then rotated back in Photoshop for better comparison.

The text was apparently calculated against the presumed horizontal LCD primary orientation. But because the pixels were rotated, several of the letterform stems (verticals) are drawing as full-pixel-width colored lines. The first “h” is especially glaring, its stem and stroke are drawn as a pair of dark red and light blue lines.

Sub-pixel rendering takes advantage of a known horizontal alignment of the three color primaries that make up each physical pixel. The algorithm seems to render text at 3x the horizontal resolution, ignoring the color information and treating each third-pixel as a valid light source to use for drawing letterforms. That 3x width is then striped with red, green and blue to match screen’s component primary ordering. (That was an educated guess)

As Steve Weller stated in the post John linked, the human eye has “pathetic color-resolution”. This fact is exploited all over the place in video, with many formats sampling color only once for every four luminance pixels.

Several things are at play here:

1. Human vision is the bifocal product of horizontally arranged eyes.
2. Most written human language uses letterforms which are vertically oriented and horizontally distinguished. Especially Latin-derived languages.
3. Most human languages read horizontally.
4. Human vision tends to be less color sensitive for motion, or when scanning information (like reading)

It all just kind of worked out perfectly. Digital color reproduction combined our horizontal predisposition with our soft and slow perception of color, and then arranged color primaries horizontally. Text also reads horizontally, and since the viewer is rapidly moving their eyes, we perceive shape and contrast before color. Additionally, Latinate languages evolved letterforms which utilize horizontal variations against a largely regular vertical syncopation. Presto: sub-pixel rendering just seems fantastically obvious.

Regarding John’s closing supposition,

“I’m not sure the iPhones rotating display is reason enough to rule out sub-pixel rendering.”

Based on everything leading up to sub-pixel rendering in the first place, most of the benefits would be lost if the underlying pixel grid was vertically oriented. The sensitivity of computer text falls across the horizontal axis. Adding resolution to the vertical axis isn’t worth the effort.

Sub-pixel rendering is ultimately a transitional technology anyway, a half-step that improves the now while waiting for a better and inevitable future to arrive. Once we start seeing iPhone level pixel-densities all over the place, sub-pixel rendering will began its transition to technology footnote.

Digital displays will someday reach a point where every physical pixel is capable of producing every color of visible light. (And someone will doubtlessly push into near infrared and ultra-violet, claiming increased realism and fidelity). Future displays will also be operating at a density where anti-aliasing may not be necessary at all.

I still think Apple’s decision to use standard anti-aliasing for the Leopard menu bar was a mistake. Unless they’ve got some spiffy high-pixel-density cinema displays ready for MacWorld and enable system-wide resolution independence in 10.5.x, switching to standard anti-aliased text rendering in the menu bar was a change that should have been postponed. The necessary hardware pool just isn’t here yet and the result is an interface that looks markedly worse than it did under previous releases.

Amazing how times change:

Me, yesterday:

The price drop on iPhone was shocking. I was all set to buy a new Nano, but the idea that my iPhone now costs one-8GB-nano less has me waiting. This seems like a big enough PR blunder, or setup, that Apple will followup with some easy goodwill. I’m still going to get a new nano, but I’m going to wait at least until the weekend.

Today Apple does it again: To all iPhone customers

…[W]e need to do a better job taking care of our early iPhone customers as we aggressively go after new ones with a lower price. Our early customers trusted us, and we must live up to that trust with our actions in moments like these.

Therefore, we have decided to offer every iPhone customer who purchased an iPhone from either Apple or AT&T, and who is not receiving a rebate or any other consideration, a $100 store credit towards the purchase of any product at an Apple Retail Store or the Apple Online Store. Details are still being worked out and will be posted on Apple’s website next week. Stay tuned.

We want to do the right thing for our valued iPhone customers. We apologize for disappointing some of you, and we are doing our best to live up to your high expectations of Apple.

I think they fully expected this reaction having done something similar to quell outrage after dropping the price on Aperture last year. It’s a win-win for Apple, if there was no outrage, then eh, they just sell more phones. If there is outrage, as there was, Apple wins, probably more.

The intial news cycle only lasts so long, Apple got some press for the new iPods yesterday, then got more as the media picked up on all the iPhone owners who felt robbed.

All publicity is good publicity.

Apple waited just long enough for things to die down a little, then grabbed everyone’s attention again with a remarkable conciliatory, gesture of goodwill. Happy customers, more coverage. The initial news cycle stretched two or three times what it was and ends on an undisputed high note.

It’s called public relations for a reason. How much does it cost to grab people’s attention? How much to stay at the top of the news cycle?

Apple is playing the game masterfully.

And my new iPod nano is suddenly half off.
