Humanity has prevailed (for now!) I'm completely exhausted. I figured, I had 10h of sleep in the last 3 days and I'm barely alive. I'll post more about the contest when I get some rest. (To be clear, those are provisional results, but my lead should be big enough)

Update: I'm alive and well The results are official now and my lead over AI increased from 5.5% to 9.5%😎 Honestly, the hype feels kind of bizarre. Never expected so many people would be interested in programming contests. Guess this means I should drop in here more often👀

Let's make a silly experiment. For every like this post receives in the next 24 hours, I will post one tip for heuristic/bot programming contests. I will start posting these as a thread in ~1h from now. I could talk about those things for days, so bring it on!

Things are finally settling down and I hope to return my regular schedule. One lesson from this 5 minutes of internet fame is that DeepResearch hallucinates far less than every journalist that wrote about me so far. Thank you all for following. It's completely crazy!❤️

Nope, just regular VS code with some basic autocomplete to speed up repetitive stuff.

Nah, I'm good. I like having no responsibilities. Well, other than being humanity's last line of defense 😅

Also, my trip around Japan is not going as planned. If you have any recommendations for things to do around Tokyo & Kyoto where I won't melt in 37°C weather, I'm all ears. I'm staying here until the end of July.

Sorry for the wait, the AtCoder finals write-up is finally here! I got overambitious and described my entire experience. I hate writing long articles, so I hope all of you will enjoy this. Since this place is not what it used to be, the link is⬇️

By popular demand*, I’ve written down my thoughts on AI in the AWTF finals It took so long, because I decided to analyze AI's code *I won't lie, I was mainly motivated by people who shared their expert opinion despite knowing nothing about the contest🤦 Link at the end of 🧵
