Also, if they can develop Left 4 Dead 2 with 23 maps (not counting variants), new weapons, new technology, new character designs, new enemies, thousands of lines of dialogue, in less than a year, they've probably got a pretty large amount of Episode Three done in 3 years.

This is the stuff of legends. I mean, holy shit, using stenography to get a landline number? It takes a whole different caliber of genius to invent shit like that. Let alone the kind of brain that can crack it.

CZ was a flop? And CS2 hasn't been announced? Holy shit we've opened a portal to a parallel universe!

Only the hive mind can crack that shit.
Not stenography. [ame=http://en.wikipedia.org/wiki/Steganography]Steganography.[/ame] Whoever first thought to open those files in an image editor was either a genius or had way too much time on his hands.
BTW, did anyone else get an update to Episode 2 along with this? I did, but it downloaded very quickly and I there wasn't any news involved... just wondering if anyone's thought to check it for some kind of new content.
I had that update downloading about a week ago steve, nothing in the update news so I haven't got a clue.
Several of the dinosaur wav files that were extracted from the new portal gcf that were not morse code sound files, were actually SSTV transmissions, and not steganography as reported in the posting.
SSTV is just an audible way to transmit an image.
Essentially what is required is to play the audio back and pipe it to SSTV software which reads the data from the audio stream and in turn displays the actual image is is contained in the data.
More about SSTV can be read here:
http://en.wikipedia.org/wiki/Slow-scan_television
There was not steganography involved.
It sounds very much like listening to the audio noise generated when you listen in on a modem.
The resulting images were analyzed and noticed that certain characters where cricled.
The circled characters where collected and ended up making a 32 character string which turned out to be an MD5 hash.
More on MD5 here: [ame]http://en.wikipedia.org/wiki/Md5[/ame]
The MD5 hash ended up being a hash for the phone number for the BBS.
The BBS itself was not encrypted. It was just necessary to use the correct terminal settings to display the content properly.
Once the content displayed correctly, a username and password was required.
The username and password was provided trough the transposed morse code that was extracted from the dinosaur wav files.

Most of us knew this. Supertoaster made the assumption in chat and some time later SPUF caught on (even though they used the wrong term.)
That video :woot: Though that guy talking over was annoying.
I think valve saw the bad company 2 trailer and wants to make sure we don't get distracted.
:facepalm:
Wasn't like the first one was bad or anything, it showed 100% of the relevant new material..
Why'd you feel the need to post an alternative for the crappy subtitles? As if anyone had trouble understanding it...
Anyhow, GDC 2010 in just a few days time, so portal 2 announced then, or before then? Or will GDC simply be the next piece in the puzzle??

What? The original had some guy talking during it and I couldn't even understand what the robot even said. Why do you even care if I posted another one? And oh, look, the one he posted is a private video now. :facepalm:
I posted it mostly because of what spammish said and I agreed with him.
