QuoteHowever, it is virtually guaranteed that a powerful geomagnetic storm, capable of knocking out a significant section of the US electrical grid, will occur within the next few decades. In fact, this may well happen even within next few years as we approach the next period of elevated solar activity, known as "solar maximum", which is forecast to peak in 2013.

QuoteThe possible extent of a power system collapse from a 4800 nT/min geomagnetic storm (centered at 50° geomagnetic latitude) is shown in Figure 2. Similar levels—10 times those experienced during the March 1989 storm—were reached during the great magnetic storm of May 14–15, 1921. A nuclear weapon would need to be a ~multi-megaton size to cause the equivalent E3 damage [15].

So I got really bored and decided to check this site out, I was initially very skeptical about having anything to do with this site.
Well, it turns out this site is pretty neat. You can pass a series of staged tests in order to gain points and get to new levels.

One level in particular that I would like to discuss involves very basic cryptography. This is level 6, where you are given an encrypted string, the generator, and an input to enter the decrypted string.

Now, in order to pass this level you have to understand what it's doing in the first place.

Try entering something simple like "1111".
You'll see it displays "1234".

This is a common method when testing types of encryption, you'll be able to spot consistencies and figure them out right away. (assuming they are simple. ROT13 uses a similar method.)

Now, you can probably already tell what it's doing to encrypt strings. Increasing each succeeding character by its index in the string.

Now, in order to decrypt this encryption, you obviously have to do the reverse. Just subtract the ascii character by that of its index in the string.


Below is an AutoIt script I wrote specifically for this level.

Global $string = "string", $x = StringLen($string), $buffer = "", $i=0, $leng=0
do
    $i+=1
    $char = StringMid($string, $i, 1)  ;select each char and parse it
    $asc = Asc($char) ;get the current ascii code
    $new = chr($asc-$leng) ;increase it by the index we are at
    $buffer=$buffer&$new ;apply the new character to the buffer
    $leng+=1
until $leng=$x

ConsoleWrite("Decrypted: " & $buffer & @CRLF)


Enjoy! If you're interested in AutoIt there are a few things that could be done better with this code, Feel free to play around with it.

Sweet! Nice to see a sorted list like this.
Thanks!

Anti-virus is unreliable. -.-

Very cool, i'll have to try it out later!
Thanks for sharing.

It's a pretty cool early step, nice job.

Looks pretty good, nice work!

USA. :]

its been a while since i played too. You play on Useast?

Yeah, I am normally in clan null@useast.

My normal game name is glyph13 or glyph89@useast (or if you see x0.Glyph in the channel whisper me!)

Hey, welcome to the forums.

Welcome, nug.  Glad you decided to join us!

heyyy =) im on WC3/SC during the weekdays sometimes... my acc is HuFF and i'm in clan unit, hit me up ;P

oh and also how is this site unique? i mean like any suggestions to make it better or any other things to add-on to it?

The header and navigation are unique, along with the colors. It has a user friendly feel and look to it. I have no suggestions at the moment.
