Podcast interview with Dan Grigsby of Mobile Orchard on Loopy’s development

Last Thursday I did an interview with Dan Grigsby from Mobile Orchard; the interview is now online.

Highlights from this interview include:

From UIView to OpenGL: the seven different implementations it took to finalize its unique — and Best App Ever award-nominated — UI.

From audio-queues to Remote IO: the four different architectural approaches he tried before finalizing audio subsystems.

The travails of trying to implement echo cancelation.

Understanding error codes

Just in case there’s someone else that didn’t know this, when one gets an error code from one of the iPhone/OS X SDKs with no other information available, it can usually be looked up in the MacErrors.h header. Just open a terminal, type:

open -h MacErrors.h

Then do a search for your error code and you’ll hopefully find a corresponding macro name that gives some indication of what went wrong.

Failing that, if you have an inkling of where the error occurred (eg. the AudioToolbox framework), then you can often find the error defined within the framework’s headers:

$ grep -r '10863' /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/System/Library/Frameworks/AudioToolbox.framework/ /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/System/Library/Frameworks/AudioToolbox.framework/Headers/AUGraph.h: kAUGraphErr_CannotDoInCurrentContext = -10863,

That was, type in Terminal grep -r 'the error code', then drag the framework straight from XCode into the Terminal, where the path will be inserted.

Traffic Shaping in Mac OS X | Mac Geekery "…Create several pipes that have a set bandwidth and other properties for all packets that get filed into them; you then add queues to those pipes that determine what priority certain requests will get in that pipe; then you add actual firewall rules to identify packets and file them into queues."

Facebook News Feed RSS

Tired of either logging into Facebook frequently, or being entirely oblivious to friends’ activities, I was searching for a way to view the Facebook front page news feed as RSS, so I could load it into my news reader and forget about it.

‘Nemik’ has created such a thing and kindly made it available. It was a bit elderly, and didn’t work with the new Facebook, so I jazzed it up a bit.

Put it on a webserver, configure it, and access the URL to view the RSS feed. Probably a very good idea to provide password protection, as well.

Use at your own risk, and Facebook, please don’t sue me.

Happy Birthday, Loopy (Thanks, Apple)

Loopy is 2 months old!

More interestingly, it’s just passed the $4000 AUD ($2640 USD, or $2050 EUR – stupid Australian dollar!) earnings point, which works out at about $500 a week. For essentially a niche app, I’m pretty damn happy.

I can’t think of any other marketplace in history where almost anyone can jump in with an idea and a little ability, and come out with something resembling a salary almost immediately. I can’t imagine the indie lifestyle has ever been more attainable.

Apple have done something amazing here, in creating a marketplace fully equipped with their mature infrastructure, their brand, and most importantly, their enormous user base. They’re basically giving developers the fruits of all the work they’ve done over the past decades in building Apple’s brand and customer base (in return for 30% of sales, of course!).

Now that’s some profitable symbiosis. Apple – thank you.

Developing Loopy, Part 2: Implementation

This is part 2 of a series following the development of Loopy, my iPhone app.

In part 1, I wrote about Loopy’s interface. Part 2 will be more technical, and will cover some challenges encountered during the evolution of Loopy from concept and mockup to working software. Or, more specifically, the stupid things I did along the way.
