okay, I figured this one out pretty fast. I used a python scblockedript to get the "computer language" (trying to avoid spoilers) and convert it into text. However, the "computer language" I got wasn't dividable by 8, which made it impossible to convert. So I took off the extra 4 characters at the end and got a result, but when I entered my result into the box it said it was incorrect. There was also a spot in the message I noticed that had two spaces between the words. I'm confused about that extra space and the purpose of the extra 4 0's on the end of the image. Any help?

you don't need to use any programs other than a binary to ascii converter.
just save the image, zoom in; you do the math.

I had a python scblockedript scan each pixel, compare the color, and print the relative binary value. Think the fault was in my scblockedript? Did you have leftover bits, like I did, after doing it by hand?

EDIT:

No, I don't think my scblockedript is at fault. Lengthwise on the image, there is 13 pixels, and widthwise there is 68. Multiplying them gives you an area of 884, which when divided by 8 gives you a remainder of 4.....

okay but 4 isn't your answer.

if you do it right by hand you shouldn't have anything left over but the binary that you should convert to ascii to get the answer.

you really don't need python for anything but the competitions around here to be honest :happy:

Then maybe there are 4 extra bits that you don't need. I'm sure if you have the binary you can easily figure out which 4 that may be.
If you want I could take a look at your python scblockedript.

No, he's right.. there are 4 extra bits, whether you do it by hand or with a scblockedript. The maths is still going to leave you with 110 bytes and 4 unwanted bits.

I think my python scblockedript is okay, it was a pretty basic one and the binary translated just fine into a sentence that made sense, so I don't think my code is the problem.
Yeah, so, I've converted that via a binary converter (minus the 4 bits on the end) and send in my result to the answer checker and it tells me it's wrong....

I'm not seeing what i'm missing here...
Can I send someone what i've been entering? Maybe someone can see something I left out somewhere.

Umm, sorry lemonpie, but I'm not going to message you with my exact way of solving the problem when you havn't completed it yourself yet, no offense :p

Reaper, check your inbox ;)

Sidenote: Could an admin please fix that above post?

It's all good, I figured it out. Thanks though.
I had the right answer, but something was wrong with the output from my binary translator, causing me to input the slightly modified (and hence incorrect) answer.

Fair enough, but surely you'd need to know the exact answer to check his.. therefore, I presume if you knew the exact answer, you'd have completed it on your current account.
