For this weeks PhotoFriday, “Best Friend,” most people seem to have gone with pictures of their slobbering dog or grinning, cutesy couples.

That’s not my style.

I found these ducks in a hotel in Zurich, the yellow one in the bathroom, the chocolate one on the bed. I thought it would be nice to introduce them. They got on famously until one came to an unfortunate, albeit tasty, end.

• Urbanized – After Helvetica and Objectified, Gary Hustwit’s next documentary is about the design of cities. “Urbanized looks at the issues and strategies behind urban design, featuring some of the world’s foremost architects, planners, policymakers, builders, and thinkers.” Can’t wait.
• 8-Bit Cities – This is awesome: maps of cities in the style of 1980’s video games.
• iPhone 4 – Case Program – I’ve not had any reception problems with mine but I’m not one to pass up free stuff…

This weeks PhotoFriday theme is “Sky-High.” My first thought was a picture from a plane but then I thought it was likely to be a bit of a cliché. Bizarrely I didn’t see many other entrants with the same idea so I went with the above image, taken on my iPhone landing back in London.

Please also vote for my entry in last weeks challenge, “Summer Fun.” I’m entry number 279.

## 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.

On Monday I gave an overview of the problem, Tuesday I looked at how those changes were announced and why they were tricky, and yesterday I looked at how I actually implemented those technical details.

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.”

The phrase “Summer Fun,” which is this weeks PhotoFriday theme, conjures up images of children splashing in brightly coloured paddling pools, beach volley ball and barbecues lasting well into the late, twilight hours. Unfortunately I don’t have pictures of any of those things. So here is a picture of a summer sunset over Brighton beach. I think walking on the beach, late in the evening while it’s still light is considered fun.
