Initially I didn't realise historical data was available for free... I was also interested in learning more about the system itself, writing a diy decoder, etc... which is why I bought one. But yeah, kind of lost track of explaining that in the post :)

Thanks for pointing this out :), I fixed it!

I really enjoyed your post, it’s a very nice write up!

Your monitor and your browser 100% affect the appearance. After calibrating your monitor, try opening the image in full resolution and take a few steps back.

For me, viewing the images on my phone makes them look off.

Thank you for pointing that out. The Atkinson dithering I was using was indeed messing with the results. I'll be updating the post shortly :)

I’ll try them as soon as I get the chance, I have perceptual luminance implemented already. I’ll compare :)

I am weighting each of the channels according to the formula in my post.

I’ll try OKLab and compare, thanks for the comment :)

You’re right it kind of isn’t finished… I had it done, then had an exchange with the author of didder and I’m still in the process of rewriting :)

Thanks for your comment! I'm glad you're seeing the same thing :) I re-implemented the linearised dithering in python and got similar results. I checked and rechecked the colour profiles in GIMP, nothing... At this point I can only hope for an expert to appear and tell me what exactly I am doing wrong.

Great catch! I would be interested in how scammers keep coming up with these new methods? How would they even validate their new attack vector? I would like to think that there’s scam A/B testing or something similar…

Thanks for the kind words!

This is highly specific to C# which was the language imposed on all participants. But I agree that some languages might be especially adept to these kinds of tasks and it would be interesting to see which.

I didn’t think of that, but I guess the conclusion as to performance of the model would have remained the same.

The game’s implementation itself was furnished with the competition by Sebastian Lague. I completely agree that writing the move logic, validation, etc… is a difficult undertaking especially when it comes to optimisation which is what allows the bots built on top to perform well.

Thanks for linking the image. You're right in my simulation there is almost no growth, even at a high count and if you're forced to bet every round you would certainly lose money. But it's a simplistic simulation and a real casino offers slightly better odds if the rules are right.

I built this a few years back. I ordered the parts from different vendors, but I got the PCBs from JLPCB. Still use it daily and love it. A few things broke but it was easily repairable.

Thank you for the reference! I will definitely amend my post as soon as possible.

Thanks for the feedback, appreciate it :)

Also thank you for the insight on RSA functionality, that makes a lot of sense! I didn't realise why hashing is used.

The issue with generating a valid string is, as detailed at the very end of the post, that you need at least a pipes before and b pipes after the digits which need to be between to pipes. That narrows the possibilities down quite a bit.

I did not know before you posted this comment... But I think in this case I did not publish any exploits so this should be legal?
