## The story so far

Last year Yahoo! announced, with no notice, a significant change that had far reaching consequences for all third party applications including my iPhone program, Yummy. This is the third in a series of posts that discusses how I dealt with it.

We’ve already talked about most of the work, starting with an overview, the announcement, the low level technical challenges and the implementation (technical and UI). All that remains it to launch it, and that’s what we’re going to talk about today.

Yesterday I spoke at a high level about my iPhone application and some changes that Yahoo! made to their side of the system. Today I’d like to talk in a little more detail about how those changes were announced and why they were tricky.

• MacPaint and QuickDraw source code – This is awesome: the original source code to two of the most important pieces of software from the 1980’s.
• If I have two children, and one is a boy, what are the odds that – Where common sense makes no sense. Sometimes. Probably.
• June 23, 1912: Computer Pioneer Alan Turing Born – “He’s also a genuinely interesting figure, albeit a tragic one. An eccentric who liked to bicycle while wearing a gas mask and who occasionally wore pajama tops underneath suit jackets, he was also a prodigious and eclectic genius.”

## Background

For the benefit of any new visitors, I develop an iPhone application called Yummy that connects to the Delicious.com “social bookmarking” website, allowing you to access and share your bookmarks using a far more usable interface than the native web or mobile optimised version of the site.

In the olden days — that is more than six months ago — to access Delicious all you had to do was enter a user name and password. As a developer it was very similar. Whenever you wanted to access something that required authorisation — adding a new bookmark for example — you had to supply the same credentials as you would on the web: a username and password. This, in web terminology, is called “basic authentication.”

• iPad App Pricing – Nice analysis of iPad and iPhone application pricing.
• The Value of Ideas – “Ideas are worthless. Execution is everything.” Or actions speak louder than words.
• The IBM Muppet Show – “IBM. The Muppets. Two venerable institutions-but not ones we tend to associate with each other. Yet in the late 1960s, before most people had ever seen a computer in person or could identify a Muppet on sight, the two teamed up when IBM contracted with Jim Henson for a series of short films designed to help its sales staff.”

• Mobile Multitasking – “The new way is to rethink the fundamental deal for processes. In the old model, processes that have already been launched get priority — once running, they stay running. In the new model, the user’s intentions get priority. You press the home button, you’re going to see the home screen in a moment, whether the app that was running was ready to be closed or not. If you want to open another app, it’s going to open immediately, even if the system has to pull the plug on an app in the background to free enough RAM.”
• Please Make the iPhone Weather Application Location Aware – As per subject line…
• iPhone OS 4 and Multitasking – What multitasking on the iPhone really means. It’s all kind of moot for me anyway since I can’t run OS4 on my first generation iPhone!

• Rejoice this day! – My sentiments exactly!
• Lost labels for your DHARMA Initiative needs – This is great. I think I’m going to have to re-label everything in the cupboard at home!
• It must have been a slow news day at ZDNet – These arguments against iPhone development come up all the time on places like StackOverflow. This is a great explanation of why they mostly make no sense.

• On Apple suing HTC – Like many people, I just don’t see Apple’s actions here being very constructive. Seems like a waste of money and good will.
• Curiosity – “Curiosity is one of the most underrated phenomena in the world. It’s ironic that people aren’t more curious about curiosity. It’s a powerful thing.”
