    Just a catch-all thread for curious questions that have popped into my mind recently and have bugged me for the past few days...

    Feel free to ask random questions of your own; someone might know the answer. They don't have to be tech-related at all...


    Anyway, here's mine:

    1) When you mount a disk image, 'where' are the files? In RAM? On a bit of your hard-drive that you can't access directly through Finder? What actually happens (apart from the obvious) when you double-click a dmg file?

    2) Following on from that, is there an easy and foolproof way to drag and drop folders to make compressed images from them? Something like the way Stuffit operates? Instead of going through the hassle of doing it all from Disk Utility?

    3) I saw this guy busking on the London Underground recently and he was standing playing some form of guitarish thing in an upright position. Never seen or heard anything like it. It definitely had more than six strings, was amplified and had quite a long neck and it kind of sounded like two or three guitarists playing at once. It wasn't a sitar or anything non-western or if it was, it was tuned to whatever a standard 'western/european' scale is. Does anyone have any idea of what I'm talking about? No pix, sorry.

    Help me sleep at night, thanks. :D

    Hopefully this will help with your second question - just tried it and it worked for me. Not perfect, but vastly easier than the 'standard' approach.

    Still, that's so damned obvious and 'Mac-like' I'm kicking myself for not even trying it! Thanks. :)

    No problem!

    As far as #1 goes, I believe the files are in the DMG file, not anywhere else on your hard disk. There might be caching optimizations, esp. for compressed disk images, but I'm pretty sure there's no need to re-write them to your hard disk... doing so would probably be a security issue for encrypted disks, for example.

    Yes! Sounded pretty amazing. And he also gathered a small cluster of teenagers with black Metallica Tshirts to listen. I gave him £2. :)

    Any well-known bands/musicians use these regularly?

    That depends on your definition of "well known". :)

    King Crimson comes to mind.

    The Stick is definitely amazing and takes a (IMO) very talented musicisan to do a good job with it.

    #1 The content of a disk image is in the .dmg file. My semi-educated guess is that when you mount a disk image, you just start a system task/call that sets up a structure that gives you access to that content. This also sets up other stuff like if a password is needed to do on the fly encryption/decryption and whether you have read only or read and write privileges.

    So the files you see are still on the hard drive within the .dmg file, but the structure that enables you to access the content is in memory. Content may be buffered in memory when you read and write, but when you unmount any outstanding writes will be flushed to disk.

    I'm probably not using the correct terms for system task and structure here, but I hope they serve to explain what's going on.

    BV, here's a Stick-based site with some good leads to artists that use it.

    There's some interesting Stick-jam videos on there.

    And Tony Levin is the Stick-man from King Crimson, so you might want to investigate him a bit more.

    When you can sit still and watch your MIND like a man trapped in a cell watches the venomous cobra that is trapped in the cell with him... he never waivers.. he never takes his eyes off the snake..

    Just SIT STILL and watch.. NEVER REACT to the ordinary MIND...
    with undivided attention and direct focus, watch your mind... You wil then, and only then become aware of TRUE LOVE....

    You should also consider VIPASSANA - http://www.dhamma.org/

    I have been feeding my dog the same dog food for 5 years (he is 6 years old)... he is a huge and extremely athletic Great Dane that gets walked 1-3 miles everyday.

    And he goes for runs on the weekends...

    Every 3-6 weeks he gets diarrhea.... I don't give him any new food or change his diet at all.. WTF?

    I have another Great Dane that is on the same regement of food.. he never gets diarrhea ....


    ???
    What is going on?

    Just a side note about dmg files: If you want them to open instantly, you can use something like Tinkertool to "Skip checksum verification when opening DMG files":

    Excellent for "known" dmg files... :)
