Steffen Itterheim has posted a really nice list of all the Objective-C 2.0 compiler directives along with examples of how to use them.

Nice!

I've added three new projects to my iOS OpenGL ES repository on GitHub. They are fairly simple examples of how to use GLKit and GLKBaseEffect. You can find them in the GLKit Stuff directory.

They're kind of rough, but they should be helpful to you if you're just getting started with GLKit and trying to figure out how to use it.

Thanks to Julián Oliver for tweeting the solution to a problem I was having getting textures to work with GLKBaseEffect.

Beaming a video with a single tap or unlocking a device with only a smile sounds like science fiction. Now, you can actually do these things (and more) with a phone that fits in the palm of your hand.

Wednesday morning in Hong Kong—together with Samsung—we unveiled Galaxy Nexus, the first phone designed for the latest release of Android 4.0, also known as Ice Cream Sandwich.



With a super slim profile, Galaxy Nexus features a 4.65” Contour Display with true high definition (720p) resolution and a lightning-fast dual core 1.2ghz processor combined with 4G LTE or HSPA+ technology. Galaxy Nexus also features the latest in software: Ice Cream Sandwich makes Android simple and beautiful, and takes the smartphone to beyond smart.

Beauty and simplicity
With Ice Cream Sandwich, our mission was to build a mobile OS that works on both phones and tablets, and to make the power of Android enticing and intuitive. We created a new font that’s optimized for HD displays and eliminated all hardware buttons in favor of adaptable software buttons. We also dramatically improved the keyboard, made notifications more interactive and created resizable widgets.

The desktop-class browser is significantly faster, featuring a refined tab manager and the ability to sync your bookmarks with Google Chrome. Ice Cream Sandwich also features the best mobile Gmail experience to date, with a new design that lets you quickly swipe through your inbox and search messages even when you’re offline. Calendar boasts a clean new look and you can zoom into your schedule with a pinch.

Connect and share
People are at the heart of Ice Cream Sandwich. We rethought how you browse your contacts with the new People app, which combines high-resolution photos and updates from Google+ and other social services. It’s also easier to capture and share your life with family and friends. Galaxy Nexus sports a high-end camera with zero shutter lag, automatic focus, top notch low-light performance and a simple way to capture panoramic pictures. Shoot amazing photos or 1080p video, and then edit and share them directly from your phone.

Beyond smart
Galaxy Nexus isn’t just a smartphone—it’s beyond smart. Ice Cream Sandwich gives you complete control over the amount of mobile data you use by helping you better understand and manage it. We’re also introducing Android Beam, which uses near field communication (NFC) to instantly share webpages, YouTube videos, maps, directions and apps by simply tapping two phones together. Face Unlock uses state-of-the-art facial recognition technology to unlock your phone with nothing more than a smile.

This weekend marks the third birthday of the G1, the first-ever Android phone. Nine releases later, more than 550,000 Android devices are activated daily.

Starting in November, Galaxy Nexus will be available in the United States, Canada, Europe and Asia. Check out the Nexus website for a product tour and more info.

As you probably know, Apple provides a bunch of functionality for manipulating objects in 2D space using CGAffineTransform. Oddly, Apple doesn't provide you with a way to extract the scale, transform, and rotation information from a CGAffineTransform and they don't provide any shearing functionality at all.

Here are some additional inline functions that I use. This adds the ability to extract component values of the CGAffineTransform and also adds the ability to create and extract shear information.

As always, this code is free to use without restriction or limitation, but has no warranty whatsoever. If you fix a bug, feel free to let me know about the fix so I can incorporate the fix.

We’re hearing from people at check-out counters throughout the country that paying with your phone is a little like magic. Just look at the ecstatic reaction on the faces of our friends who made their first Google Wallet purchases last Thursday.



Today, our partners American Eagle Outfitters, The Container Store, Foot Locker, Guess, Jamba Juice, Macy’s, OfficeMax and Toys“R”Us are rolling out an even better Google Wallet experience. For the first time ever in the U.S., at these select stores, you can not only pay but also redeem coupons and/or earn rewards points—all with a single tap of your phone. This is what we call the Google Wallet SingleTap experience.

With Google Wallet in hand, you can walk into a Jamba Juice, American Eagle Outfitters or any other partner store. Once you’ve ordered that Razzmatazz smoothie or found the right color Slim Jean, head straight to the cashier and tap your phone to pay and save—that’s it. You don’t have to shuffle around to find the right coupon to scan or rewards card to stamp because it all happens in the blink of an eye.

The Offers tab in Google Wallet has been updated to include a new "Featured Offers" section with discounts that are exclusive to Google Wallet. Today, these include 15% off at American Eagle Outfitters, 10% off at The Container Store, 15% off at Macy’s and an all-fruit smoothie for $2 at Jamba Juice. There are many more Google Wallet exclusive discounts to come, and you can save your favorites in Google Wallet so they’ll be automatically applied to your bill when you check out.



Organizing loyalty cards in your wallet is getting easier too. Today, Foot Locker, Guess, OfficeMax and American Eagle Outfitters are providing loyalty cards for Google Wallet so you can rack up reward points automatically as you shop. More of these are on the way.

One more thing—in response to user feedback, we’ve improved transaction details for the Google Prepaid Card with real-time transaction information including merchant name, location, dollar value and time of each transaction. Here’s what it looks like:



Finally, a special thanks to Chevron, D’Agostino, Faber News Now, Gristedes Supermarkets and Pinkberry who are now also working to equip their stores to accept Google Wallet.

It’s still early days for Google Wallet, but this is an important step in expanding the ecosystem of participating merchants to make shopping faster and easier in more places. If you’re a merchant and want to work with us to make shopping easier for your customers and connect with them in new ways, please sign up on the Google Wallet site. And if you’re a shopper and want to purchase a Nexus S 4G phone from Sprint with Google Wallet, visit this page.

Jeff Atwood of Coding Horror has an interesting post today about being a developer for Apple's ecosystem. We'll leave aside for now the fact that Jeff isn't and has never been an Apple developer and is, in fact, a strong proponent of Microsoft's developer stack. Despite that flaw, I usually enjoy reading Coding Horror. I think Jeff's a smart guy with a lot to offer the world in terms of insight about software development.

But…

Jeff's premise today is that third party Apple developers "serve at the pleasure of the king", which is absolutely true. But, he finishes his post by saying he would never develop for Apple's app stores because of the chance of "being thrown under a bus" by Apple. Fair enough, we all have different tolerance levels for things, and his assumption here is essentially correct. Apple developers run a risk of having Apple compete directly with us if our product is successful enough. It happens, perhaps, to .01% of us, but it does happen.

I want to run with Jeff's metaphor a bit, but first, I need to address a couple of points in his article.

The first point I want to talk about is his claim that if Microsoft were to ever do something as audacious as release a product with the same features as one of their third party developers

…developers would be screaming bloody murder and rioting in the, er, blogs and web forums.

Wait… what? Excuse me? What the hell kind of fantasy world does one have to live in to think that Microsoft doesn't, wouldn't, and hasn't competed with their own third-party developers. Microsoft practically made a sport of it in the nineties, and has continued to do it since then, albeit less obnoxiously. I mean, have we forgotten that Microsoft was convicted by both the US and the EU of abusing their monopoly power to compete unfairly. Microsoft used to routinely use their market power to put smaller software companies out of business in order to gain control of a particular niche of the software industry.

And what were the third party Microsoft developers doing back then? Screaming bloody murder?

Nope.

They were defending Microsoft, and understandably so. The hand that feeds and all that. Those developers knew that being assimilated by Microsoft, or being unfairly competed against by Microsoft, were risks of doing business in that particular market and they deemed it worth the risk, much the way that iOS developers do today with Apple.

The second point that I think needs to be made is Atwood's implied assumption that because Marco Arment isn't up in arms over Safari's Reading List feature (which duplicates many of Instapaper's features), and isn't ranting to anybody who will listen, that it means he's "a loyal subject of the king". The implication being that Marco will put up with any treatment that Apple chooses to dish out, no matter how unfair, because he's a good whipping boy.

Which is a completely inaccurate characterization.

I don't know Marco personally, but he's one of the very few people I follow on the Internet who has consistently come across like a grown-up. Marco knew that getting sherlocked was a risk he faced by participating in Apple's ecosystem and decided that it was worth the risk. When that risk turned into reality, he accepted the consequences like a grown up. Anyone who could condemn a man for acting maturely should be called out for it, and that's exactly what Jeff is doing here. Marco's response to the Reading List feature was nothing less than admirable.

Virtual Geography

Now, back to Jeff's original metaphor of App ecosystems as countries. Let's talk a little bit about the Apple Kingdom and also about the neighboring countries where, as a merchant, you might choose to peddle your wares if the King's terms aren't acceptable to you.

The Apple Kingdom

As Atwood noted, the Apple Kingdom is a monarchy, ruled by a King. By Jeff's own admission, this king is a benign king, making decisions that he feels are best for his citizenry (consumers). He's not perfect, but generally his decisions have served the populace well, and they are happy and prosperous. The Apple Kingdom has beautiful paved roads and a great system of railways, and state-run stores within walking distance of every single citizen in the country. The king has invited even the smallest merchants to use this infrastructure to sell goods in exchange for a small percentage of their income and so long as those merchants follow some guidelines that the King has set (and, admittedly, may periodically change) in order to make sure his citizens have a good experience in his stores.

The Apple Kingdom is large, and its citizens are fairly affluent. They regularly shop at the King's stores and enjoy buying things there. Even tiny merchants are finding ways to make a comfortable living by being able to reach all the citizens of the country. Sure, not all merchants are succeeding. Even the best roads and stores aren't going to make a poorly run business profitable or get people to buy spoiled produce, but the opportunity is there for any one who wishes to sell goods to do so with minimal overhead and startup costs.

The King, however, is also something of a merchant himself, and sometimes he will sell at his own stores. He doesn't sell much, but when he does, sometimes he's selling the same types of products as some of the merchants in his kingdom. The King, of course, doesn't have to pay a percentage of his income to use the trains, roads, or stores, though. In even rarer cases, he'll find a product in the stores he likes so much that he wants to provide it to all of his citizens for free, which basically makes it impossible for the original merchant to sell that product any longer.

Now, the Apple Kingdom is not the only country in the world, and the King doesn't prevent anybody from emigrating or, in fact, even from exporting products to other countries. When deciding whether to pack up and go to another country, you need to make sure that your destination is going to be better than where you are now, so let's look at these other countries.

Androidistan

The largest neighboring country is an enormous country called Androidistan. Androidistan doesn't have a king, but instead has dozens of local and municipal governments of varying types and quality. Their national system of government is probably best described as anarchy. Androidistan's infrastructure varies greatly from province to province, with some roads and trains being free for anybody to use, and others requiring payment. Many provinces have their own stores where anybody can sell, but it's hard to find what you want and the quality of the goods is generally kind of poor, though there are exceptional products if you're willing to look for them. Unfortunately, there are also dangerous products sitting on the shelves as well. Poisoned produce and other deadly items disguised as legitimate goods.

Although there's a lot of people in Androidistan, most of them don't really like to buy goods at the government stores. They like to go in and make a meal of the free samples, but most don't really like to actually buy anything and shoplifting is rampant in these stores. In fact, it's often considerably easier to steal a product than to buy it legitimately because many of the stores aren't very well run.

Most merchants have found they can't make enough money selling their goods in Androidistan's markets, so they've tried placing stickers on their goods advertising other products. Some merchants are making a really good living doing this, but many more aren't even covering their costs.

Windowsland

On the other side of the Apple Kingdom is the relatively large country of Windowsland. Windowsland was once prosperous and has a huge amount of industry, but the country has been stagnating somewhat during the recent move toward smaller merchants. The government has recently started updating their infrastructure and building stores modeled after the ones in the Apple Kingdom. Windowsland has started a heavy advertising campaign trying to get merchants to sell their goods there.

Despite a great infrastructure and clean, brightly-lit stores, Windowsland has been having limited success in moving to the modern age of small merchants. Their large industry is still going strong, though, and in the long run, likely their stores will start to do a good business. Someday.

Oh, did we mention that Windowsland is also run by a King? He charges the same percent of income to use his railways, roads, and stores, but has placed fewer restrictions on his merchants in an attempt to lure them to sell in his country. Windowsland is a pleasant enough place, but there's just not all that many people going into their stores yet.

The Democratic Republic of WebOS

This small country had huge potential, but recent mismanagement and ineptitude have basically shut the government down. There are a few citizens roaming the streets still in a bit of a daze, but most have left for better-run countries.

The Blackberry Oligarchy

The Blackberry Oligarchy, which actually has two kings, has gone in one generation from prosperous world power to third world country due to its inability to change its ways. Citizens have been leaving this country at an alarming rate and the remaining citizens have little faith that their pair of kings will be able to fix the problems given the frequent power outages and decaying infrastructure.

There are several other small outlying countries in MobileWorld, but these five pretty much cover the major markets that merchants would want to sell into.

Epilogue

Metaphors are easy to stretch to a point that they become meaningless, and I probably crossed the line a few paragraphs back, but the point is this: all ecosystems have their benefits and their downsides. In the old days of boxed software, instead of a single benign king, you had to deal with a dozen tyrants (software chains) to get your goods on the shelf, and they took more than half the sale price in exchange. If you didn't want to deal with them, you could instead choose to work through a distributor who took another large chunk of your gross income in exchange for dealing with the tyrants on your behalf.

In every market at every time the risk of competition from a bigger, richer competitor has existed.

Part of Atwood's argument is that even good Monarchies can go bad. Sure they can. So can good democracies. Let's take what Apple might be someday off the table. We can't fault people for not staging a revolution before there's an actual reason to revolt.

Whether you do it explicitly or not, going into business means you're accepting certain risks in order to obtain certain rewards. When bad things happen in business — when risks (anticipated or otherwise) turn into actual problems — acting like a twelve year-old and whining to the Internets doesn't make things better. You buck up, find a way to fix it, or move on to something else.

So, yeah. We Apple developers serve at the pleasure of our King, and we know it. In exchange, we get access to millions of citizens who want to buy our products. A tiny percentage of us will end up competing directly with our king at times, but overall, life is pretty good in the Apple Kingdom for us merchants.

And, while we'd be glad to have you among our ranks, Jeff, you're more than welcome to pack up your gear and move to a neighboring country if you think life would be better for you there.

Mobile technology and the web have made it easier for people around the world to access information and communicate with each other. But there’s still a daunting obstacle: the language barrier. We’re trying to knock down that barrier so everyone can communicate and connect more easily.

Earlier this year, we launched an update to Google Translate for Android with an experimental feature called Conversation Mode, which enables you to you translate speech back and forth between languages. We began with just English and Spanish, but today we’re expanding to 14 languages, adding Brazilian Portuguese, Czech, Dutch, French, German, Italian, Japanese, Korean, Mandarin Chinese, Polish, Russian and Turkish.
To use Conversation Mode, speak into your phone’s microphone, and the Translate app will translate what you’ve said and read the translation out loud. The person you’re speaking with can then reply in their language, and Conversation Mode will translate what they said and read it back to you.

This technology is still in alpha, so factors like background noise and regional accents may affect accuracy. But since it depends on examples to learn, the quality will improve as people use it more. We wanted to get this early version out to help start the conversation no matter where you are in the world.

We’ve also added some other features to make it easier to speak and read as you translate. For example, if you wanted to say “Where is the train?” but Google Translate recognizes your speech as “Where is the rain?”, you can now correct the text before you translate it. You can also add unrecognized words to your personal dictionary.

When viewing written translation results, you can tap the magnifying glass icon to view the translated text in full screen mode so you can easily show it to someone nearby, or just pinch to zoom in for a close-up view.

So, like others, I was tempted to write a defense of the iPhone 4S after all the pundits and naysayers came out last week calling the iPhone 4S "disappointing". I'm glad I never found the time. As it turns out the iPhone 4s doesn't need anybody to stand up for it.

1,000,000 phones sold on the first day of pre-orders. That's 400,000 more than the iPhone 4.

And, that's not counting the number that will sell on October 14th when they arrive at the Apple Stores in 7 countries.

There's also a large batch of countries that don't get the phone until October 28, and a whopping 40 more countries (including China, where new Apple Stores have been shattering sales records lately) that won't get the iPhone 4s until some time in December.

Yeah. Disappointing. You guys in the media sure nailed that one.

It's been fascinating seeing how many people have responded to the death of Steve Jobs exactly the way I did. It's truly amazing how many people who never met the man feel not just that the world has lost somebody significant but that they themselves have lost a friend.

Hearing others express exactly what I'm feeling? It helps. And, for the most part, the media has been right there with us, responding to Steve's death by focusing on his impact and the good he has done.

I really hope seeing how many peoples' lives he has touched is helping Steve's family and friends get through this.

But not all of the media has chosen to focus on the good. I won't link to any of the actual articles, but Gawker and the New York Times top a short list of media outlets that have chosen to focus on Steve's flaws and to stand up and shout out to anybody who will listen that Steve was… well… human. Imperfect. Flawed.

There's a custom in modern society that's often called "respect for the dead". It has nothing whatsoever to do with the dead. The dead don't care what you say about them. It's about the living who cared about the dead, and they do. It's because they care that mourning is such a difficult process. Painful. Sad. It's not a time when you want reminders of the flaws of the person whose absence you are trying to come to terms with.

No human with with a shred of empathy or decency chooses to publicly criticize the recently departed, famous or otherwise, regardless of how they felt about them. Doing so is an act of cruelty. It's hurtful. Little. It's kicking people hard when they are already as low as they can be.

For those, like me, who care, but didn't know Steve Jobs personally, people like this are an annoyance. They're just another crass, classless obnoxious Internet loudmouth that we have to make an effort to ignore.

But for Steve's family, friends, and coworkers… the people who really knew him, it's a hell of a lot more than that. It breaks my heart to think that they might read those articles.

Shame on you, New York Times. You're better than that. Shame on you, Gawker. You should be better than that.

I haven't had much time for blogging lately. I have about a half-dozen unfinished blog posts in my queue, but have been too busy to finish any of them.

One of the things keeping me busy right now is work for Apple through MartianCraft. This work, in many ways, is a dream come true for me, as I wanted to work for Apple for years and never managed it.

I started programming on an Apple ][+ in 1980 and Apple has been a part of my life ever since then. I don't need to look much further than the desk I'm sitting at to realize just how much my life has been impacted by this company called Apple started in a garage by two guys named Steve. I make a living using Apple's products and developing for Apple's products, but more importantly, my life is better because of their products.

I took a few hours away from my desk this evening and returned to the news of Steve Jobs' death. I came back to news that quite literally felt like a kick in the stomach. And I mean literally. My stomach hurts.

It seems odd to feel this way about a man I never met. I've only once been closer to Steve Jobs than the front section of Moscone West or North, and that was when I accidentally knocked into him on the show floor at MacWorld one year. But I feel like an old friend has died. I'm fighting back tears, and maybe I should be ashamed of that.

But I'm not.

Steve died far too young. I think a few tears are in order.

Earlier this year, we introduced the Google Docs app for Android. Since then, many users have downloaded the app and enjoyed the benefits of being able to access, edit and share docs on the go.

Today’s update to the app makes Google Docs work better than ever on your tablet. With an entirely new design, we’ve customized the look to make the most of the larger screen space on tablets. The layout includes a three-panel view, which allows you to navigate through filters and collections, view your document list, and see document details, all at once.

Looking at the details panel on the right side, you can see a thumbnail to preview a document and its details before opening it. From the panel, you can see who can view or edit any doc.

These features are now available in 46 languages on tablet devices with Android 3.0+ (Honeycomb) and above.

You can download the app from the Android Market and let us know what you think in the comments or by posting on the forum. Learn more by visiting the help center.
