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 th

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 onl

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…

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 allow

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 c

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

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.

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.

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?
