That's not how public/private key cryptography works. If it did, any script kiddie could grab the private key in transmission.
The reason the private key is called so is becasuse it is never transmitted. It stays on the machine that came up with it.
Here's how it works, and we can assume both machines do the same thing for each other. One comp comes up with a private key and public key pair, where things encrypted with the public key can only be decrypted with the private key (and not with the public). Then, the machine can send the public key plaintext (or with some other form of encryption, which we can assume can be cracked much easier than the key pair cryptosystem we're using for the bulk of the data). The receiving machine uses the public key to encrypt it's data and sends the encrypted data.
Now if we assume any transmitted data can be evesdropped upon, the hacker has our public encryption key and the encrypted data... but he doesn't have the private encryption key! The data is useless to him! (Unless the key pair is weak, the data is weak, or the hacker has the hardware to brute force keys, but we'll assume the users are smart enough to avoid the first two and the cryptosystem uses a long enough key to make the last one futile.) The first computer gets the encrypted data and decrypts it with the private key.
A similar process, reversed, is used in certificates. They are encrypted with a private key, and the public key is made available. Assuming sufficient mechanisms are in place to assure that the public key does in fact belong to the original computer, any message decryptable with the public key shows that the message must have originated from the only legitimate computer with the private key.

Sorry I don't have any mod points so I can't mod you down at the moment. But I'm sure other slashdot members will be more than happy to drive you into the ground.
Neither the radioactive icon or the clock symbol may mean anything in the future. They're cultural references... we're not born with the knowledge of what they mean. Archaeologists might figure out that the numbers are numbers, maybe even that they are a date and time, but the radioactive symbol would only be figured out by trial and ERROR.
Cultural symbols will not evoke the same emotional reactions in different cultures. This even would include the universal NO sign... it may mean nothing in the future.
I am a Norwegian, and I am saddened by the new religion that has Europe in it's grips. There are various sects in this religion, but they all have one thing in common, the big "Satan" is the US of effing A.
That's funny, I'm an American and I subscribe to that religion (and I know many other Americans who do). Stupid government.
Today marks the one year anniversary of the complete elimination of digital piracy. Projected results by the RIAA and MPAA would have made them both $60 billion richer in this year had their predictions been correct. But, as has been the trend for the past 10 years, with the increased pressure on pirating has resulted in a DECREASE of revenue. Top analysts agree that this is due to less propagation of digital movies and audio. In addition, they speculate that most people who pirated digital media in the past likely would not have bought the hard media had piracy been unavailable.
In related news, both the RIAA and MPAA are expected to file for chapter 11 later this month.
My college blocks SMB (I assume you're talking about Windows Network Neighborhood... Macs call it SMB, right?) network browsing, although you can still navigate directly to an IP (the actual SMB port isn't blocked). Although that's ususally enough.
They can't block SMB itself though because the network uses it for printer sharing in computer labs and sharing of ITS files to users.
Of course a fun little unintended use is that I can print anything on any printer from anywhere on campus. Bwhahaha.:D
There's some enlightening dev notes on the Mozilla Wiki (I don't have a link at the moment, google it:p). Two of the more interesting highlights were a universal search function, and filters for bookmarks that work like Vista's Smart Folders (pop in some parameters, and any content matching that appears in the folder).
So I guess I could make a History folder that holds all the slashdot articles I've visited. I would include a Page Title filter of "Slashdot |" and then it would show every article Places has seen me visit.
THIS is what a good webmaster should aim for:

Hashes can't be decrypted (at least, the ideal hash cannot). That's why they're so secure (ideally, again).
When the user enters a password, that password is hashed and compared with the stored hash. Thus the real password is never required to be decrypted or exposed.
Well your solution could use a bit more thought... if a Mac freezes up or crashes (not at all uncommon I hear) then an alarm goes off... pretty soon the manager is going to axe it.
Have your router keep logs, and check them regularly.
If you notice someone's broken in, simply break in to THEIR computer over your wireless network and fill their harddrive with [animal]se and tub[woman]. Problem solved.
Long answer: Yes, and they didn't fix the problems you needed the hacks to work around either.
To it's credit, I did notice one new rendering feature I liked, now ANY element can support:hover and:active attributes, not just the a tag. Of course Firefox and Opera had this already...
Again to be fair, I myself haven't dug deep into rendering changes.
- Kids will edit an MP3, half the volume, upload it, and then show mom/dad that the maximum volume is too low. This might only work so long, unless the mom/dad isn't too technologically inclined and can be lead to beleave the iPod volume degrades over time.
- Kids will download a hack to reset the password.
- Kids will flash the firmware or reset the bios or otherwise erase the user preferences, thus unlocking the volume control. This one is probably real easy.
- Kids will edit ALL their MP3s and turn the volume as far up as possible, even possibly if the waveform ends up flattening out.
This might satiate certain groups for now, but if I came up with this in five minutes I'm pretty sure Apple doesn't REALLY think this will solve the problem. They might be able to use this as political leverage to say "not our problem anymore"!
I see several possibilities:
- Spammers copy and paste the blue ribbon into their spam templates in 1/100th of the time it took Goodmail to come up with and implement it.
- Spammers sign up for Goodmail to send some of their spam out, in quantities that will allow the cost to be worth it. The spam folder in your e-mail just became worthless.
- I refuse to use Goodmail, and my legitimate e-mails start ending up in Spam. I encourage users of services that do this to switch to "a better e-mail service with better filters", namely one that does not support Goodmail.

This year's second place could improve their idea enough to become next year's first place.

Probably the same reason why the US is #20 in the Top 20 Education Systems of the World.
More like seeing in-game billboards with ads on them.
