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.

Author here, thanks for submitting :)

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?

Thank you! I have to give credit to my friend that provided the assembly though.

Thank you very much! Salut d'Autriche :)

Fixed it... No clue how that slipped through, thanks for noticing :)

Thanks for the feedback, appreciate it. I wanted this to more entertaining than informative, but I understand why this might mislead.

- I agree that the section on pkcs#1 is at this point irrelevant, I left it in just to mention that fact. But I will probably take it out now :)

- Concerning the part of misusing RSA: My understanding is that you usually append the signature at the end, after a copy of the data which is not done here. I believe they are misusing it here because no library for RSA supports this use case, to decrypt using a public key you always have to provide the message and signature. This isn't possible here because the message is encrypted. So I think they are misusing RSA.

This is a really nice write-up, makes me want to try it out. It seems this could enable a sort of "multiplayer" functionality with a RAG approach. Maybe for researchers wanting to compare their findings or text RPGs?

Hey HN,

I am a dev from Austria and participated in the recent chess bot competition started by Sebastian Lague. I wrote this short article to summarise what I learned and I hope you enjoy it!
