Popped up for Ciro Santilli on April 19th 2026 after solving Project Euler problem 993.
The problem is available only as an image. Furthermore, the problem image itself, i.e.:
wget -O secret.png https://projecteuler.net/resources/images/bonus_secret_statement.png?1738588439
(I hope it's not fingerprinted to my login lol) must be passed as an input of your solver.
The output of the program is another image of Euler with caption:
THE SECRET WORD IS MY FIRST NAME
so and the final answer must be inferred to be the string:
Leonhard
ChatGPT web 5.4 solved it directly from the image.
This section is about official bonus problems of Project Euler.
These sometimes pop up after you solve another problem, and it is not well documented when they show up.
According to their copyright statement, these problems are copyrighted unlike the others, so we can't reproduce them here. But we can give answers I believe.
This section is about the main problems as opposed to the bonus Project Euler problems.
2026-04-17: display broke after it touched a table lightly. Not sturdy. Replacement of original 400 pounds so not worth it.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
