    I found a thesis, that contains the code snippet. Is the answer somewhere there?

    Enym, you're on the right track. Also, I would throw some spoiler tags around that post just for safety's sake.

    Nudgery:

    Nudges provided in this post will include hints that include information hinted at in posts before it.
    If you wish, you can look at this post and get all hints given in this thread before this post was made.

    ------------------------------------------------------------------------------------

    26-1 Suspicious Trading

    Nudge:
    Hmm, our images don't have any color in them. They're barely greyscaled.
    Is that a footnote at the bottom of "Financial Operations Attracting Attention" ?

    Bigger Nudge:
    One image is primarily white, one is primarily black.


    Biggest Nudge:
    BL_CK W_TCHM_N
    __A__ _A____E_

    Repeat the process you just did to those lines of text to the images.


    What Did I Do? BIG SPOILERS - MIGHT BE TOO MUCH
    YOU ARE WARNED
    [Spoilers]
    GNU Image Manipulation Program (GIMP)
    Image > Mode > Indexed > Binary

    Some data is lost, IMO it is negligible.

    (No, that isn't written in an ancient Celtic language.)
    Squint.

    26 -2 Deep End

    Nudge:
    Is there a method you know of to extract selectable text from images?
    Do you understand all the terms in the instructions?

    Bigger Nudge:
    ptical haracter ecognition
    (you may have to shop around to find the best one)

    Service I Used - but you'll have to decode it
    ASCII-TO-HEX.com
    68 74 74 70 3n 2s 2s 77 77 77 2r 6r 65 77 6s 63 72 2r 63 6s 72 6r


    Could word you get after performing this process be the answer?
    Or could it be a step along the way?

    Do you know what a dark pool is?
    It's not an unlit place to swim.

    Biggest Nudge
    Their trading strategy is really dependent on internet speed. Latency matters for this sensitive strategy.

    ------------------------------------------------------------------------------------

    26-3 Source Code

    This One is broken down into two Parts:


    Part One: Getting Into The PDF

    Nudge:
    Black Watchmen, Did You Find Our Latent Secret In The Dumped Message?

    Man, Sir Elton sounds different than I remember him on this track. He's ghostly.

    Have you found what search engine the document is talking about?

    Farther Nudge:
    Do you have the guts to see Sir Elton's spectral message? I mean, do you have the gumption? Do you have the audacity?

    Our search engine needs parameters. When? Where?

    Farthest Nudge:
    Remember, we're tracking down stock trading methods here - sometimes a few letters represents a whole organization.

    This search engine company allows us to see satellite imagery whole planet if we want to! We can start way out in space, and just go farther in until we see a whole continent, then a country, then a province, then a county, until we're looking at an entire town! We can narrow our field of vision not just once, but over, and over, and over, and over again!

    Part Two: Understanding the PDF

    Nudge:
    As mentioned in a previous hint, the wording in this puzzle can be a bit tricky.
    You are tasked to find out "What Program SIGIL is working on"
    This isn't so much a question of "What is the name of the project" but more along the lines of "What does the program accomplish/do?"

    The PDF doesn't make too much sense without context, can you find its content elsewhere?

    Bigger Nudge:
    Remember, we've only focused on financial matters so far.
    Do you remember what their trading strategy was?

    In order to get that kind of speed, they want to optimize the process as much as they can.

    Trades are performed when a party (in this case, SIGIL) issues a "command" to a brokerage.
    This "command" travels over the internet through a chosen "path" and tells the broker to buy/sell on the party's behalf.
    Think about this in the context of their strategy - how can they optimize here?

    Biggest Nudge:
    The next line is a pretty loose hint, don't get caught up in specific words or terms - think conceptually.
    Dijkstra came up with a method for accomplishing something similar to what SIGIL is attempting.

    This "command's" "path" needs to be optimized INTELLIGENTLY.

    "Optimized" or "Well-Connected" devices have become quite popular in the past decades. We have made these things "intelligent."
    Think about phones, watches, homes and even bombs.


    Bonus Clarification Nudge:
    What's the antonym of "antonym?" - when you see the quotes, find those.


    What an interesting mission - I spent 75% of my time (minus the time it takes me to write these, which is often double the actual solving time, I write as I go) on figuring out what to AFTER I got the PDF open.

    So I am on part 3 and I have already decrypted the PDF file. However, I cannot figure out the meaning of the PDF contents. There are several routes to take to find the answer but don't know which route. If someone could offer some advice that would be great.
