Sounds good

No idea what image you created, so it's hard to hint if it's wrong way or not. But, it may be a good way (you should read this as a hint ).

After Redford wrote to challenges solved, I have finally looked at it. :) I just do expect there is nothing hidden in png encapsulation. Yup. You should try some statistical analyses until you find something very interesting. It is also possible to solve this challenge "by accident", but ...

Seems like I've found the solution in a similar way to TheBigBoss. I wanted to test if there's something hidden in the pixels (treated as raw bytes), so I converted the image to BMP and looked at the image using trigram view in Veles (a tool which I'm one of the devs). To my surprise, I found someth...

The problem with the last egg is that it was padded with a null byte and a percent sign. Not sure if my solver is wrong or the author did something wrong, seems he wanted to pad the text with two nulls. That was my third approach. I used Z3 with Python bindings and it was quite straightforward. Full...

Redford@: are you sure the fill of remaining regions you did is correct? Arenot there other almost equally good fills? I'm quite sure about that. If you zoom enough you can see "seems" on badly matched pieces. Yeah, there are many similar pieces that can match well, but if you put one in ...

Hippo:
I did it in very similar way, but with more automation. I'm curious whether I'm the only one who reconstructed the whole image, because the dark/black parts were really hard.
TheBigBoss:
Not for me, I still haven't solved 'Awesome Internets Vid'

Thanks!

AMindForeverVoyaging: how about bok? I think he can fix it too.

We need a new admin, otherwise the site will get worse and worse :/

Are you sure that's RS-232? RS-232 transports just raw bits: https://en.wikipedia.org/wiki/RS-232#mediaviewer/File:Rs232_oscilloscope_trace.svg That standard doesn't say anything about transported data (e.g. bit order, encoding etc), it could be any RS-something. I rather asked about the protocol in...

The ranking got broken many months ago, but unfortunately nobody takes care about the site.
I mailed admins about this problem (and others), but they don't have time to fix it/don't respond. I hope some day a new person will take over hacker.org and fix all that issues.

I've solved this task searching in English dict for 4 letter words with specific distance between letters (like word[1] == word[2]), so I still don't know what's the used protocol/encoding. Does anyone of you know what it was?

Thanks,
Redford

The description is misleading. Don't worry about them, you'll notice soon what was lost

I think it's not the place for revealing the whole solution, I'll PM you.

I did it on windows
However, you should know both linux and windows tools and select appropriate one for each challenge.
