HELP NEEDED

As the map is not working anymore: Does anybody has a backup of the challenge positions on the map? This is the best we have right now: https://github.com/Entkenntnis/hacker.org/issues/4

OP here, I have spun up a small instance, you can try the current progress there: https://substantial-chisel-louse.glitch.me/ Challenges like "Dungeon Master" are probably gone, rip, as we don't have access to the source code. it doesn't even build, NPM ftw Because there is no build step 8...

I started with hacker.org about 15 years ago and immediately fell in love with this type of challenges. Fast forward to today, I have created my own project called Hack The Web ( https://hack.arrrg.de/en ) that takes direct inspiration from here. It's now translated into English, so if anybody is cu...

well, solved it now, by pure chance while searching for some other topic ...

so the hint would be: don't try to solve this on your own.

the prime days of this site are over, unfortunately. I have made a little graph to confirm this: The graph shows the number of active (e.g. solved at least one challenge) users in a 28-day window (scrappend from the solvers.php pages), the first solved challenge was on mar 28, 2008. You can see a pe...

There is no topic about this challenge yet, so I am starting one.

I have found a bit of pattern in the punctuation, but have no clue how to decode it, because it does not look like ascii or anything I know.

Can somebody give me a small hint?

A small remark about this project: If you look closely, this site isn't really dead - there are still new people joining it, doing challenges, asking questions ... and adum is also reachable by mail. Soooooo .... I have decided to pause my project for a open-source version of this site. It was fun t...

Is this challenge possible at all? Unsolved until today ...

Adum gave me permission to reuse his texts, assets, etc. Thank you very much, adum!

Hello everybody here! I got really nostalgic recently: This site great and I want it to stay alive. So I thought: Maybe it's time for a rebirth? My aim is to reimplement the challenges, make it open source and modernize the UI (a bit). I want to keep it very close to the original content. You can se...

I'm glad to hear your opinion. Don't be afraid of criticizing lisp - I'm NOT a missioner on some holy ... :) You are completely right in your two points: Doing arithmetic maths often awkward and the efficiency on hardware-level is low. In both cases I would prefer another tool, maybe Matlab/Mathemat...

Seems like almost most people don't use Racket or they don't know it ... Maybe it's time for some advertising :D : Most of coding is about transforming data. You have input that you give to a function and you get some results back. You don't need much more to build a turing complete language and tha...

Anyone here who uses Racket as their favourite programming language?
After a struggle with VB, Java and C# I switched to Racket and fell in love with it. Expressive, clean and beautiful code, fast compiler, vast API ...

What are your opinions?

I used the value of 8/pi form OEIS and got 3748893571891.069, so the accepted answer is the exact solution. But as tails pointed out correctly the the correct solution should by one less, because the python code is only a approximation. I think the poster of this challenge hasn't run the python code...

when you past the numbers into notepad++ and double-click the "capital" letters the solution will be quite clear

I love this feature coloring the same word in the document...
