    Adam –

    I think your comments on Nike’s thinking the data would be more valuable that selling a pair of shoes is very insightful. It never crossed my mind, but it makes perfect sense.

    Just one more reason I love this podcast so much!

    I found an article about the iPhone on Engadget,seems like Apple is not sitting around on their laurels.

    …and Steve Jobs should be happy about this.

    Thanks, Adam, for your excellent work for us. Your podcast is more than fun and useful, it is essential for me these days and always a delight. You have a great radio voice and write a good script. May we have 150 more!

    I don’t know why I did not think of dropDMG for spliting up large images… Just after your show I used Disk utility to Make a sparce Image, Then using carbon copy cloner i made a full backup to it. When it Finished i took the sparce image into dropDMG and split it up into 12 4.4Gb smaller images and then burned them onto 12 DVDs. VoilÃ¥ A colpete system wide clone on 12 DVDs (I cannot afford a firewire HD)
    I finally have a full secure backup of my system, and it was so easy to do i recomend this for all penniless mac users B-)>

    Thanks Adam looking forward to the BIG 200

    Great show, one again, Adam :-)

    regarding Wiebetec and their enclosures/adapters: They seem quite a bit overpriced $119 for a FW enclosure or $249 for the dock to connect HDs without enclosure…You can get USB2-IDE oder USB2-SATA adapters for $20 or $30 (maybe even cheaper). Okay, you’ll have an extra power adapter and two cables more to plug in, but hey…more that $200 saved…that converts to two at least 640GB backup space (320GB Seagates, maybe even more). And that it’ll take one minute longer to plug them in shouldn’t be a problem – at least no for home and semi-professional use.

    When I send in my mac for apple care. I keep the password on my account the same and don’t give apple it. What I actually do is create a new adminstrator account and set OSX to autoboot into that account, that way OSX will stop anyone accessing files in my home directory even if they try a sudo, yet still provides full access to every other part of the system on that admin account.

    When I first got the Nike+iPod Sport Kit installed, I was pleased to see two personal “Calibration” options – one for my walking pace, and one for my personal running pace.

    I went down to my local hardware store and bought a “Walking Wheel”, a device that contractors use to measure long linear distances over 1 mile, and is accurate to the very inch. I found a long, even stretch of road near my home and used the walking wheel to measure out an exact 1-mile track. I made markings for each 1/10 mile section of road.

    Prior to completing the calibration, the Nike+iPod kit registered the 1 mile walking distance as .97 miles. That’s about 158 feet off-target. As soon as I completed the walking calibration sequence, the iPod nano interface indicated that the generic .97 mile was now exactly 1 mile for me. Woo!

    My next time out was designated as the running calibration which registered .94 miles – a significant 317 feet short of accurate. Again, once I told the iPod nano that I’d completed an accurate linear mile, it acknowledged me and thus my running calibration was complete.

    After the calibrations were done, my next two ventures out proved that the Nike+iPod was accurate between 1/220 and 1/660 of a mile. Once the transmitter is properly calibrated, it should remain accurate to your original pace and stride – at least until its battery fails a year or so later, or your constant work-outs increase your pace and stride. Any other inaccuracy experienced is likely due to analog human error.

    In short, do not use the Nike+iPod Sport Kit without properly calibrating it, othrwise your workout stats will most likely never be accurate. If users can’t find (or don’t want to use) a Walking Wheel, find a public high school or college with a professional running track. Those tracks are typically 400 meters, or .248 miles – not an even conversion, but four laps and a brief walk-off would give you a one mile workout.

    For those who need accurate readings, the calibration sequence is critical.

    I need to double check, but I think with an admin account password you can change the owner on any directory. That means all someone would have to do is choose Get Info… on your home directory, change the owner to the new admin account you set up for AppleCare and enter that password. Now they own your home folder and can access anything they want.

    Thanks for the advice regarding backup of large files. I am in the UK, and have been wondering what to do with a Terrabyte of video footage I saved recently on disk, while covering a conference.

    I just bought a WiebeTech ComboDock 4, and two Hitachi Deskstar 250GB drives. I am backing up now. Thanks a lot. :-)
