Finding where the keys are on your HDD is the easy part, accessing and using them is the task that takes months... [Simple way to find the location of the keys. Image your HDD. Purchase file from iTunes. Image your HDD compare the two images. The new key(s) (and the file itself) must be in the bits that changed.]
Sure. Of course, the guys working on DRM at Apple aren't idiots. If you were an engineer charged with defeating this type of attack, what would you do? I can tell you what I would do, I would start changing a whole load of bits on your harddrive, not because it's necessary, but because it makes it that much harder for you to find the stuff that changed.
It's a moot point anyway. Any file that you download from iTunes is going to be at least a few megs in size. The key is going to be somewhere in the order of a couple of hundred bytes. Which bytes amongst the several megs are the key? They aren't necessarily contiguous, they're almost certainly encrypted by another key hidden elsewhere in the system, and they may even be fiddled by a virtual machine after decryption, just to muddle things up a little bit more.
Finding the approximate location on the HD is simple. Fiding the actual key in the right order is an extremely difficult task.
As someone who does this for a living, can you comment on my read of the hacks that have been released in the later post http://forums.macrumors.com/showpost.php?p=2917258&postcount=96. It still seems to me that where DRM has been hacked has relied on key retrieval or finding the weak spot in the chain.

Um, of course DRM hacks rely on either retrieving the key, or finding the weak link. They are the only two attacks possible - grab the data after the program has decrypted it for use, or find the key/algorithm so that you can do the decryption yourself. At the moment the first attack is nearly trivial to implement, although that will change a bit when the manufacturers start moving on to a "Trusted Computing" style platform. All you need to do is write your own audio driver that sits between the computer and the real driver. It picks of the data and stores it as it's sent to the speakers.
The second solution is much more difficult, but far more elegant. It allows you to keep intact all of the metadata associated with the file (track name, lyrics, album name etc etc). BUT, you have to be clever enough to recover the key.

seems sketchy, Apple wouldnt put it all in VZ's hands at all to keep it secure, Apple does a fine job at that already.
And i dont think itd be that much of a difference if they release att / vz iphone separately they do device updates for portables, desktops differently and the usual ipod updates etc.
But the fact remains how are they going to exactly implement two separate phones for carriers that use different cell tech, and implement them properly
I highly doubt there will be a vz iphone for as much as id like one...not until other 4g/lte services are out in the wild

Well, MacBook Air didn't really impress me. I would never have any real use for it, but obviously Apple thinks someone will since they have it. And I'm sure someone will. I could sit here and type out everything that doesn't make me happy about it, but we all already know.
Overall, I wasn't really impressed. I'm happy with what I already have....for once.

Curiouser and curiouser.
If it's a fake, whoever did it did a pretty interesting job on it.
It looks plausible.
I mean we had:
iphone 3g
iphone 3gs
why not
iphone 4
iphone 4gs
Which would give incentive for people to go for the white one I guess.
then the 5 comes out later?
It would be 4S ;)

Those that bought the 5.5G is going to be similar to the 4G situation when they released the Photo. One'll be the higher end ones (60/120 set), while the other'll be "music-oriented." That, with the lowered prices and Zune release, you got a concoction Steve Jobs sees as "all in the money."
Hell, we remember last year's new nano release followed up in just months by the iPod with Video.

that they were able to put all that together and package it in a consumer friendly way
let's wait until it is released
personally i found the clicking around in the adress book just for dialing _not_ userfriendly
and the whole internet communicator functionality presented was what ? writing email ?
what exactly is the market for it ? the businessman ? those very likely have already laptops and sophisticated mobile phones/palms etc. and second the features are hardly aiming at them either
will they be able to use the mobile phone as a modem for their laptop ?
who else ? the person who tricks out mobile phones with all kinda gimmick programs etc ? hose rather choose phones with java etc.
i don't know i still who they plan to sell it ... sure there are mac enthusiasts (i would take it too when given as a present) but 10 million within a year without any real range of products ...
not like the apple tv thing would be any better... nice in concept but when your only way of putting content on it is downloading it for high prices on the internet then you essentially end up with a small streaming box for music + photos
or did i miss the step where you could record tv shows and put movies on it from your dvds ?
edit: that aside i'm interesting to trying it out in person... partly because i actually field tested/helped to develop/debug software for a unit,( which i hope i never see again BTW), which had a touchscreen, a built in mobile phone with GPRS (god i hated it), WLAN and camera/barcode scanner
having done this for 2 months i can feel the pains the developers went through during their 2 1/2 years at apple

Well that's just wrong... they aren't completely removing location tracking in anything. Just fixing "bugs" that stored to much information in a file on your phone.
FAIL
your correct, based on Steve Jobbs response to this which was pure BS we can never trust that the files do NOT get sent out, so with this and their sweat shops in china i think enough activists, governments around the world and companies will shut apple down, so its not just Congress coming to ask Apple why it was still there after a year ago when they where sued for using it to COLLECT POLITICAL VIEWS:
Lets see why :
Wikileeks, Wall street, Oil Giants, allot of these people used macs and iphones, I think Congress is doing the right thing indicting Apple for violations of privacy on US and foreign citizens becuase if they do nothing other nations will pull the plug forever, Israel already is planning a blockade on the devices

Thought I would post here instead of starting a new thread. How do I get bonus points, all I am reading is -advmethods and setting up a passkey. Would it be worth it on a i7 720qm at 1.66ghz? Would it complete a wu in 4 days?
This passkey sounds like a big deal should I be using it on all me machines?
With the console client for windows, is there a way I can close the window with out it stopping folding, kind of pointless having the window constantly open. Surely it can fold in the background?
Thanks guys :)
On an i7 720 you won't get bigadv units done in time to get bonus points also I have an i7 980x that hasn't gotten any bigadv units even though I have it set up to get them. I suspect some recent changes on the server end are allowing only certain cpu's to get bigadv units and i7's probably aren't getting them. as far as the passkey I'm not sure it makes any difference for someone like you, I don't think there are any other wu's that get a bonus...
You can minimize the window and it will keep folding...

"Thanks" might work in a pure support form. But for news discussion, it makes little sense.

Perhaps a "Relevant" button then.
I guess leaving it as a +1 button is pretty much the same thing without using a word.
*shrug*
I just think it may be more troublesome than helpful to have a -1 button. If someone disagrees with a post, they usually respond with an argument. If they agree, unless they have something to add, hitting the +1 button would work, and it would clear up the "Agreed" and "+1" posts.

It's obvious that Steve Jobs was going to release the True Video iPod soon. I think they intended to release the true video iPod in October when they announced Movie downloads. Something must have happened that the iPod was just not ready, so they scrambled and made some minor upgrades that they intended to do anyways.
Apple knows it has to get it right or it could be a big disaster. Their goal is to release it before the holidays, but if for some reason they can't, it will be released at Mac World. I think their main issues that have caused it to be delayed is the battery life and the screen cover. The battery life has to be from 4 to 6 hours and the screen has to have some kind of protection that won't be damaged if it is touched constantly.
If it is going to be released it will happen anytime from now until the second week of November or during the first week of December. If it does not happen during these two time frames it won't happen until Mac World.
Great post. I've been saying this all along. The widescreen iPod is a severly delayed product. And don't give me semantics about how an unannounced product can be delayed. That's just Apple's way to shirk around the responsibility that comes along with a deadline.
This product will not drop during the holiday season. Who knows if it will even be ready by January.

How much thought and research went into "Downhill since Tiger."?

/It is a rather long quagmire of posts. Frankly, I see little value in back quoting myself. If you really want to have fun the Snow Leopard launch is solid gold with Spotlight database problems, endless Safari crashes, and the still persistant GMA X3100 oddities. Even after I have had everything short of the display replaced...
You get old and jaded. It is even more tiresome when every one hit wonder decides that Steve and me are always right. Hit the independent thought alarm. Hunt for the astroturfer. You are either with us or against us...
I am using OS X just like many others here. It does not mean that I love every minute of it or feel the need to be a sycophant for any corporation.
Everyone loses when you use car analogies.
No, I'd say Snow Leopard is about 80% better than Tiger and 20% worse. I mostly skipped over Leopard, and went from 10.4 on a G5 to 10.6 on a Mac Pro. There are quite a number of improvements all over the place that show it's clearly the result of taking a look at earlier versions and saying "wouldn't it be better if...", and then acting on it. There are a few steps backwards though, the biggest one for me being the incomprehensible mutilating of Expos�. Fortunately there's a nice hack which restores the correct behavior (and makes the dock look better), but it's a little annoying to have to re-apply that after every update.
--EricExpos�, Spotlight, and Finder have taken the most hits since Tiger. Though it is nice to be able to scroll in windows that are not in focus or to be able to support certain applications from lazy developers.
Otherwise I would rather have the older and much more productive behaviors for non-linear interfacing and searching. I should not be required to make work arounds or simply give up on trying to replicate Tiger.
I have given up on Spotlight ever working like it once did and I do not want to replicate the hours rebuilding all my metadata. I have just regarded it as something that is no longer of value to me. My MacBook is sadly not much more than a glorified address book and music server for the foreseeable future. It really kills the motivation to replace it and an annoyance to maintain a OS X based machine in my inventory once it is no longer useable.

The campaign is great, and you really get attached to the characters.
I don't know what you're all talking about.
No, having to replay sections over and over and over and over, just to learn what is killing you is not great. It is crappy 90s game design, that we should not have to deal with in 2010. Crappy checkpoints mixed with crappy enemy and team "AI" (if you can call it that) make for a really crappy game. I'm turning it down to Recruit just to get it over with, so I can flush it from my mind as quick as possible.
I beat both MW games on Hardened, and about half of the levels of each on Veteran. While the plot in both was ludicrous, they were at least fun. Lots of clear objectives, teammates who would stay out of the way, and very few of those "monster closet" moments (grrrrr, Favela :mad:) Those games were fun from start to finish. Black Ops is just a mess of crazy flashbacks cutscenes, messy game design, and terrible direction.
Yeah. I liked MW2's campaign better. It may be because I am from the DC area so it was quite weird seeing it war torn.
How about Fallout 3? I've never been to DC, but I find it really funny how when I see it on TV or in movies now, I recognize so much of it, and where things are, just from my hundreds of hours in that game. :D
