I have been doing heavy unix administration and engineering for a good portion of my life of all flavors of unix. I have never seen permissions just randomly 'flipping around'. Sure, you can blame a 3rd party product for mucking around in the file system and changing things. The real question is what does 'repair permissions' do? What subset of files is it querying as the 'authoritive source' of information of how the permissions should be set? And if this thing exists, why can't 3rd party developers muck that up too? Very bizarre...

I believe it only fixes files that belong to the base Mac OS X system. It references what the originally installed permissions should have been. I don't know where the master list is. It will also fix files with permissions that are set to an invalid number. (e.g. owner/group settings to an invalid uid or gid which is never really valid.)

Permissions are sometimes flipped to an incorrect setting by installer programs. In the UNIX world, people didn't install software under various "admin users" with various third party installers (they're usually install scripts run under sudo), so it's not as common. It does happen sometimes though.

Fixing permissions is a bit of a red herring for most problems, often people restart after fixing the permissions, which fixes some problems by cleaning out the /tmp folder. There are a few permission-related problems, but MacFixit's recommendation of repairing your permissions before and after updating your system is a bit ludicrous as well. It's not a magic bullet.

Any time an installer under OS X pops up the dialog requesting an admin password it effectively does a sudo - there is just no difference to installs on other Unices.

For the most parts, repairing permissions is an urban legend like update-prebinding was on 10.0. I wonder what will replace it - maybe clearing out foreign language versions?

If your system really slows down and you are not able to run top, reboot. If it stays slow, check the file systems. If they are OK, check the hardware.

I suggest ALL current Series60 phone users that lost hope in the N90/91/N70 designs should take a SERIOUS SERIES60 look at the announced N80/N92 phones.

N80 slider with QUADband 850/900/1800/1900Mhz EGPRS (thats GPRS & EDGE full class 11 not 10; its not a typo its the upload speeds equaling the dl speeds in EDGE) also the 3G is ready for Cingular's upcoming 3G network 1900/2100Mhz (the later for Europe)..
And all of todays announced Nseries have the new browser that Apple has.

If anyones ever used NetFront or even Opera for the Series60 or other Symbian OS based smartphone your in for a treat if this new browsers capabilities can deliver!!

For all of you interested in what the "Experience It" link looks like, I've added a screenshot.

But clicking on your screenshot crashed Safari!:eek:

Mind if I add one thing? If you're having problems, and you're running beta software or nightly builds, uh... think. :)
