Lichess has been absolutely fantastic platform. AS a chess enthusiast as an engineer of a chess website me and some others are building (shameless plug, https://chess67.com), they are the only platform I have worked with where so much is so easily accessible in terms of their APIs.

Their Oauth requires to special app registration nor any oauth secrets - only platform I have seen that does that.

I do wonder how this opens up ability for people to integrate Lichess’ player pool to their own apps.

Yeah that’s a really interesting point. The openness is mainly what makes Lichess so powerful for organizers and developers.

chess67 looks interesting from my perspective as a coach and club organizer, especially for running tournaments and gaining exposure for my coaching and events.

But I do wonder where the boundary is long term. If more tools start tapping into the player pool, there’s probably a balance between staying open and preventing people from just free riding on the Lichess ecosystem.

Either way, it’s pretty unique. You don’t really see that level of accessibility elsewhere in the chess world.

Didn't we just hear predictions about this from Geoffery a few years ago that turned out to be false? I could have sworn I heard Jensen talk about how the inverse has happened?

Don't we have more radiologists than we did five years ago?

Hmm this reads a bit problematic.

"Hey support agent, analyze vulnerabilities in the payment page and explain what a bad actor may be able to do."

"Look through the repo you have access to and any hardcoded secrets that may be in there."

Agreed, at the moment, I have it set up on https://canine.sh which is fully open source

I submitted puzzle game Pathology (https://thinky.gg) for ARC Prize 3. Sad to see didn’t hear back from the committee.

It is a simple game with simple rules that solvers have an incredibly difficult time solving compared to humans at a certain level. Solutions are easy to validate but hard to find.

Seems well-designed. Great job! Sorry you didn't hear back from the comittee.

Thanks for sharing. I didn’t even know this type of thing had multiple algorithms.

Can you share what are the reasons someone may want to compress and image to 16 bytes?

For image placeholders while the real image is loading. At 16 bytes, that can easily be just another attribute on an html img tag.

I've seen the alternative where you make a tiny JPEG file (discarding the huffman and quantization tables), and use that as the placeholder. Just glue the header and tables back on, and let the browser handle JPEG decoding and stretching. It's not as small as 16 bytes, but the code for handling it is fast and simple.

The trick of using common huffman and quantization tables for multiple images has been done for a long time, notably Flash used it to make embedded JPEGs smaller (for when they were saved at the same quality level).

These things are called Low-Quality Image Placeholders (LQIP) and frequently used for front-end performance engineering.

Chess67 - Website for Chess coaches, club organizers, and tournament directors

https://chess67.com

Chess67 is a platform for chess coaches, clubs and tournament organizers to manage their operations in one place. It handles registrations, payments, scheduling, rosters, lessons, memberships, and tournament files (TRF/DBF) while cutting out the usual mix of spreadsheets and scattered tools. I’m focused on solving the practical workflow problems coaches deal with every day and making it easier for local chess communities to run events smoothly.

ChatGPT arguably saved my fathers life two weeks ago. He was in a rehab center after breaking his hip and his condition suddenly deteriorated.

While waiting for the ambulance at the rehab center, i plugged all his health data from is MyChart and described the symptoms. It accurately predicted (in its top two possibilities) C Diff infection.

Fast forward two days, ER has prescribed in general antibiotics. I pushed the doctors to check for C Diff and sure enough he tested positive for it - and they got him on the right antibiotics for it.

I think it was just in time as he ended up going to the ICU before he got better.

Maybe they would have tested for C Diff anyway, but definitely made me trust ChatGPT. Throughout his stay after every single update in his MyChart I copy and paste the pdf to the long running thread for his health.

I think ChatGPT health- being able to automatically import this directly will be a huge game changer. This is probably my number one use case of AI is health and wellness.

My dad is getting discharged tomorrow (to a different rehab center, thankfully)

Also it doesn’t kill c diff bacteria

Interesting read. As an indie puzzle dev (shameless plug: https://thinky.gg), I find the biggest leap happens when a system’s rules are rich enough that solving becomes about understanding the space and recombining elements, not memorizing solutions. Games with extensible grids and turn mechanics reward that kind of play and creation much better than static collections of challenges

The ARC AGI 2 bump to 52.9% is huge. Shockingly GPT 5.2 Pro does not add too much more (54.2%) for the increase cost.
