This work makes a humanoid robot do simple parkour moves by looking with a depth camera and choosing the right move on the fly. The big deal is that it turns lots of small human moves into long, real-time robot behavior, without hand-coding every transition or retraining for each new course. A humanoid robot is usually good at steady walking, but it often fails when it has to do fast moves like jumping up, vaulting, or rolling, and then keep going to the next obstacle. The hard part is that you cannot easily collect training data for every possible obstacle shape, distance, and mistake, so robots end up learning a few moves that only work in a narrow setup. This work starts from short clips of real human parkour moves, like stepping over, vaulting, climbing, and rolling. It uses motion matching, which is basically a smart “pick the next clip that fits best right now” search, to stitch those short clips into a long, smooth plan that looks like a human doing a whole course. Then it trains a controller with reinforcement learning (RL), which means the robot learns by trial and error to copy that plan while staying balanced and not falling. After training separate expert controllers for different moves, it compresses them into 1 controller that uses only onboard depth sensing and a simple “go this fast in this direction” command. In real tests on a Unitree G1 humanoid, it can clear multiple obstacles in a row, adapt when obstacles get moved, and climb a wall up to 1.25m.

Last night I asked Claude Code to build me a simple script: pull on-chain data from Polymarket and sort wallets by win rate Nothing ambitious. Just wanted to see who is actually making money on 15-minute BTC markets The terminal finished in about 20 minutes. Hundreds of addresses, columns of numbers, nothing interesting And then 1 wallet caught my eye 200+ trades per day, consistent profit every week, almost surgical timing precision. I reread the line 3 times. A real person does not trade like this I fed the address back into Claude Code and asked it to break down the pattern. Half an hour later I had a full strategy reconstruction on my screen The bot (and it is definitely a bot) pings Binance and Bybit every 100ms monitoring volatility compression on BTC. When it drops below 0.08% it enters Up and Down contracts simultaneously at 25 to 35 cents each. A pure straddle. 1 side burns, the other flies to a dollar. At a 30-cent entry that is 3 to 4x per position And so it goes in circles. Dozens of times a day I sat there staring at it for about 10 minutes $13K to $25K in daily profit from a single wallet. Not a trader with intuition, not an insider with information. An algorithm that found a hole in market mechanics and methodically milks it You can check the trade history yourself: After that I went looking for whether anyone else is tracking this wallet. Turns out yes. Found a Telegram bot that tracks wallets like this and copies their trades automatically I connected it to the same address just to see if the entries would match what my terminal was showing. Matched perfectly Still testing on minimum amounts for now: But the fact that you can stand next to an algorithm like this in real time is something that simply did not exist a year ago

And this? This is the very first piece of artificial limestone, YES, CaCO3, YES, hard as f and YES, waterproof, what I made from… Wood ash ONLY!!! 100% caveman tech! Now look at the color of this thing. How would you describe it? May I say it has the color of the pyramids? Hell yeah! Why? BTW: this is just the binder. Add original, natural limestone and fossils and you’ll en up with “natural” limestone. (With a bit of potassium residue.) Any questions? The secret recipe maybe? Anyone interested? Here you go: 1. Burn 🔥 everything around you and collect the wood ash 2. Burn natural limestone (calcination) to produce quick lime Steps 1. and 2. can be combined into one step. 3. Make wood ash lye the traditional way, by dripping drip 💧 water on wood ash and collecting the water that went through the ash. Any vessel will do but an oak barrel is the traditional way doing it. I used a plastic bucket with holes at the bottom. The wood ash lye is mostly KOH and K2CO3. What we need is CaCO3. We need to change the letter K to letters Ca. We’ll do it by adding the letters Ca to the liquid. 4. Add quick lime (CaO) or hydrated lime, slaked lime (Ca(OH)2) to the lye until it stops bubbling in vinegar. (We badly miss a decent video at this point, Marcell!!!) 5. Add (or don’t add) fossils = natural limestone rubble to the mix, stir well 6. Get rid of of the excess liquid through a nub Now any expert can tell you that this will never make a stone because of two reasons: 1. Billions of years and 2. High pressure are needed Well, no. The first point is just total nonsense, and although the second has something in it, it is false. Virtually ANY pressure will make it, including my current technique of squeezing it in a kitchen cloth. I’m not kidding. No pressure- no stone, that is correct. But only a minimal level of pressure, using my bare hands is enough to push the freshly made CaCO3 molecules close enough for crystallization (calcit) to begin. And here we are.
