You can get that from the public key. No way you can derive a private key from a 128bit key.. so this has nothing to do with an 'application key'. The iphone already uses cryptography extensively with 1024bit keys signing all the firmware upgrades (which maintain the chain of trust from the master public key burned onto the CPU.. so you can't break into it by modifying firmware files).
The other option is it's a string of random numbers from some retard who wanted some publicity..
Steve jobs has previously referenced the Symbian model.
In that you have developer keys, which are free (the SDK download is free), tied to your IMEI and allow you to sign applications for your phone as much as you like. These can access most functions but not critical phone functions.
This leads to two classes of apps:
1. 'official' apps, which have been through the vetting process and got a 'proper' key - this is much easier than it used to be, (there are plenty of small companies making profit selling apps at $15 a throw so it's not huge money). 2. 'homebrew' apps, distributed unsigned, which you manually sign using your own signing key. Harder to install, no quality guarantees.. but open to anyone who can chuck a few lines of code together.
Whether he's thinking of something like that remains to be seen.
A signing key is going to be a 1024bit RSA certificate, the same as apple use for their firmware (but different, obviously).
If this is anything it's a fingerprint... and a fingerprint on its own is pretty useless - you can derive it from any signed application.
What it *might* be is the ramdisk key, but for which version? (that key changes with each version - it's calculated by the IBSS bootloader differently for each version). But that's unrelated to the SDK.
Other phones seem to have no problem allowing 3rd party apps on them.. even ones by independent developers.
The iphone is locked down for a single reason - to stop people breaking out of the AT&T monopoly. Apple don't give a crap about a jailbreak or 3rd party apps really.. you wanna break your phone, they'll happily sell you another one. The do care about the kickbacks they get from their chosen provider in each country.
Depends if the 15 seconds includes the 4 'do you really want to do this?' dialogs..
If it's *possible* to configure an OS to take 15 seconds to delete a file (on a 64bit dual core and a clean, default install, it's no more than 5-6 seconds.. way slower than XP but usable for testing) then that OS is broken. Delete is a fundamental system operation that should be fast.
Err, that's what Superfetch is. Maybe read about it? Yeah, that's the thing that keeps the hard drive thrashing 100% of the time, stopping the power management cutting in and draining your battery.. and doesn't do a damned thing to the app loading speed.
I don't get why 4100 lumens is going to set things on fire - a home projector can often output 5000-7000 lumens and I haven't seen them cause any fires recently.
Of course projectors have fans in them, but still....
Just to play devils advocate, pure heroin isn't that bad for you.. you frequently hear of doctors who've been on it for years without anyone knowing it.
In that case it's the illegality itself that directly creates the danger. Same as making alchohol illegal.. people would be drinking contaminated whiskey etc. and die of that rather than the drug itself.
Same with cocaine - the thing that makes your nose fall off isn't the drug it's the other crap.
It's frequently pointed out that the withdrawl symptoms for caffeine addiction are as bad or worse than heroin... but we don't ban that (although I believe in the US it's illegal to give it to under 18s?? Might be wrong about that though).
Once you start looking into these things it's never as clear as 'these drugs are safe' and 'these drugs are bad'.. it's a value judgement (and often a financial one).
We have a few in the UK but they don't seem to *do* anything but wander around in suits on hot days (when everyone else is in t-shirts), carrying bibles the size of house bricks and shouting at the tops of their voices at anyone who wanders too close.
I can't imagine anyone actually giving them money, but then someone has to pay for all those suits...
Not to mention amazon.com announcing "Warner Bros. has announced plans to discontinue its support of the HD DVD format after May 31, 2008." on every HDDVD page.
Ordinary consumers do use amazon.. and they all now know it's over.
At the moment it's cheaper to buy and HD-A3 and 5 free movies than 5 HDDVD movies (based on an average price of $33 per movie, which is the amazon average according the eproductwars).
So Toshiba are basically giving the things away now.
I saw it happening just like you did.. and I'd give the marketing guy who pulled it together a bleedin' medal. The timing was immaculate - right before CES so that the HDDVD camp were left thrashing around and had to cancel their keynote.
It was a move to 'end' the war, and it worked. It's over.
And in the second week, HDDVD players were selling for virtually nothing, and there were no special offers on Bluray.
Unfortunately HDDVD supporters keep dragging this NPD statement up as if it was new. It was made after the first week's collapse in sales for HDDVD.. they still haven't made any statement on the second.
Aside from the fact that the iphone battery barely lasts a day on standby, have you never been on holiday? Can't take an iphone... it'll be flat after the first day (after about 8 hours in fact) then what do you do for the other 13 days?
I usually have 3 on rotation which gives me about about 9 days on a normal smartphone (N95) and by then I might have found the power source to charge at least one of them. If not I switch off the phone overnight and it lasts the whole two weeks on 3 batteries.
Err.. is that yes I want to copy it, or yes I want to move it, or yes I want to do both somehow, or maybe one of them randomly, or based on the day of the week?
OTOH it works, doesn't require much pre-installed (it does have some requirements, as my attempts to run it on os-400 found), and is universal. Universally hated, but still universal.
Make sure that the code is compiled by a trusted agency.. preferably several public agencies in parallel. The resultant binarys must all match otherwise they're scrapped. The verified binary is then signed using a key only available to a third trusted agency. All of this process must be in public, and every part has the right to send qualified observers to watch every step.
It goes without saying the original code must also be open to scrutiny.
Have you considered that your ISP isn't throttling?
Bittorrent's normal behaviour is to switch between clients.. many of them are on slow connections that dropout constantly anyway. It's also generally slow, because trackers measure upload/download and only allocate the faster links to those with a good upload - which penalises DSL users over other users for example.
If you want to see the effect of this try it on a decent leased line.. you'll see the speed start off really slow..1k/sec then slowly build until you're at about 10% of the download and your upload starts to exceed double your download, then up to about 60k/sec, then by about 50% of the download (by then the ratio is about 30:1) you're at max. bandwidth - about 1MB/sec in my case.
Of course it means it's always better to FTP - by the end on the leased line I've typically send about 200* the amount of data I've received, which goes on the bandwidth bill and of course clogs up the network. On FTP it's 1*, by definition.
OTOH on the DSL line at home I see *exactly* what you're describing.. bittorrent bumps along at 1k/sec until the tracker dumps you entirely. My ISP definately isn't throttling in any way (I can talk to the MD on IRC any time he's around and he definately wouldn't lie about a thing like that).
Slashdot Mirror
I reckon it's a fingerprint.

Given the two, yes you can vote out a big government.. and it's in their interest to keep you happy. Corporations care only about their shareholders.
OTOH *anything* getting too big is bad.
you realise God = Allah ? Sssh.. don't tell the fundies.. on *either* side.

Unethical?

Actually it's two weeks.
And in the second week, HDDVD players were selling for virtually nothing, and there were no special offers on Bluray.
Unfortunately HDDVD supporters keep dragging this NPD statement up as if it was new. It was made after the first week's collapse in sales for HDDVD.. they still haven't made any statement on the second.
That's old. This week the same sales ratio held up *with* the Toshiba firesale and with no BD offers.
They really aren't selling as well as slashdot makes out sometimes.
That's fine if you only know about 3 people and call them all the time. Any standard phone can do this.
For those us that actually *use* phones that won't cut it.
Iphone is:
Click top of phone
Slide
Push to select phone application
Push to select keypad (hell only knows why ths isn't default)
Dial number
Select Dial
Every other phone is
Dial number
Press dial.
For a 7 digit number that's 12 for iphone and 8 for every other phone.
Aside from the fact that the iphone battery barely lasts a day on standby, have you never been on holiday? Can't take an iphone... it'll be flat after the first day (after about 8 hours in fact) then what do you do for the other 13 days?

Ahh but Windows users get no more
"Do you want to copy or move this file?"
"Yes/No"
Err.. is that yes I want to copy it, or yes I want to move it, or yes I want to do both somehow, or maybe one of them randomly, or based on the day of the week?
Sounds about right.
OTOH it works, doesn't require much pre-installed (it does have some requirements, as my attempts to run it on os-400 found), and is universal. Universally hated, but still universal.
Windows has supported '/' as a path separator since about NT 3.1...
The only app that doesn't work with it is cmd.exe, because it uses that as a command line switch.
Make sure that the code is compiled by a trusted agency.. preferably several public agencies in parallel. The resultant binarys must all match otherwise they're scrapped. The verified binary is then signed using a key only available to a third trusted agency.

Then I might trust it.
