When trying to test and debug something to which you have limited access, always make sure you know how to undo anything you try, without having to wipe it and start over. And after verifying that what you did needs to be undone, don't reboot until you've undone it.

I have yet to figure out if all my iPod customizations will survive my inappropriate use of "launchctl remove com.apple.mDNSResponder". And I hope, if I do have to wipe it, that Apple isn't pushing firmware 2.0 just yet.


Update: It's fixed. The same Windows program I used to "jailbreak" the iPod lets me switch it from Recovery Mode to Normal Mode. And after that things seem to be working fine; "launchctl list" includes mDNSResponder in the list (unlike after I first did the remove).

I think I could've undone the "launchctl remove" with "launchctl load /System/Library/LaunchDaemons/com.apple.mDNSResponder". But I'm not eager to test that anytime soon. It would be nice to have a working Linux program that does what ZiPhone does, though.

This week we gained possession of a pair of 8GB iPod Touches, through a surprisingly generous rebate program.

The iPod Touch is unlike any previous iPods, but is very similar to the iPhone. It's basically an iPhone without the phone, camera, or bluetooth. That doesn't sound like it leaves much, but what it leaves is high-resolution video iPod functionality, plus wi-fi networking, built on top of a miniature Mac OS X complete with web browser, email client, and other programs.

Apple's firmware doesn't allow adding apps that aren't already there, other than using web apps designed for the iPhone/iTouch platform. (A new firmware version coming soon will open this up a bit, but not by much.) However, people have figured out ways of fixing ("jailbreaking") the firmware to allow installing third-party apps, and there's even a de-facto standard packaging/installing system to make it easy to get and install programs.

So yeah, quite the fun toy here.....

Everyone who listens to MP3s knows (or should know) that MP3 is a lossy medium; in order to get a file that's only about 10% the size of the uncompressed music, some frequencies are thrown out based on how well the human ear hears them. You just don't get as good a sound from MP3 as from the source CD.

But wait! It turns out that the sound engineers producing those CDs are now using MP3-through-iPod-earbuds as the reference for how the music sounds. And when there are things that sound great in the original CD-quality music that they don't hear or doesn't sound as good on the iPod, they'll cut them out!

The reason is that these days the music is considered most likely to be heard on an iPod, so that's what it's optimized for. It reminds me of the cell phone catch-22 of the past 5-8 years: As more people got cell phones, fewer used pay phones, so pay phones started disappearing, forcing more people to get cell phones, perpetuating the cycle until there are hardly any pay phones left. Similarly, as more music is heard on reduced-quality MP3, more music is optimized for MP3, prompting more people to listen to that music where it sounds best, forcing even more music to be produced for that lower-quality medium.

I do *like* the convenience of MP3, but I'd still like to have the better sound of the CD available! Besides, I probably encode MP3s at a higher quality than most people.

Now I dread the day when music production is optimized for hearing as a ringtone.....
