This month brings us a hot new Gorillaz track. But track of the week brings the remix to the lead single, Stylo as mixed by Alex Metric. It’s a total disco/dance track, four-on-the-floor, laced full of overdub and falsetto. Imagine if the Bee Gees had a Macbook with Serato Scratch and Logic, this is the music they’d be making. Comparing it to the studio/radio version of Stylo it’s hard to tell that they’re the same song. Alex Metric has taken the hook (which is fairly disco in its own right) and made a dance floor banger out of it.
Debugging iPhone App Submissions
In December, I posted about how to debug iPhone code signing issues. We’ve had a ton of developers building apps and the submission process to Apple’s iTunes Connect is far from straightforward. Here are some tips on how to debug your iPhone app submission. Most of these are specific to the pre-release of Flash Pro CS5, but all the certs stuff should apply all the same.
- Export your Distribution P12. Make sure it has a private key and a public cert. Use openssl to verify (instructions below)
- Download your Distribution mobileprovision. Open it up and sure that it has the right App ID (search for the string <key>ApplicationIdentifierPrefix</key>)
- If you’re using Flash Pro CS5, ensure you’re on Beta 4 or higher.
- Publish your app for App Store
- Rename the IPA to ZIP and unzip. Keep the ZIP.
- Dump your codesign for the .APP that’s inside the unziped folder and make sure it matches your Distribution P12 (must have the line in the dump which says “Authority=iPhone Distribution”).
- Inside the unzipped folder, look for an embedded.mobileprovision. Make sure it’s the same exact file as the distro mobile provision you downloaded in step 2, just renamed.
- Verify the inside of your all looks roughly like this the image below.
- Upload your ZIP to iTunes Connect.
Here’s an example of what the inside of the .APP file should look like. Key things in here are for YourAppHere to include an embedded.mobileprovision, Default.png, Icon.png, Icon-Small.png and of course your app’s binary (YourAppHere). The rest should be automatically generated when your app is packaged. It’s also probably a good idea to keep your file name to letters and numbers.
Lastly, for debugging your p12, use:
abansodmbp:~ abansod$ openssl pkcs12 -in ~/Desktop/asdf.p12

Track of the Week: Let Me Take You Out by Class Actress
Track of the Week returns after a week hiatus with Let Me Take You Out by Class Actress off of Journal of Ardency. This is a fun little indie song with very retro, synth’ed out production. Elizabeth Harper, the vocalist and songwriter has great vocals that sound feathery except during the hook when she holds the sound. Journal of Ardency is a great little six track EP that is full of songs like this (and a great name for an EP, btw).
