This is a great way to recruit / be recruited and to find bugs you otherwise may not have. Win win.

✨ New HW challenge prize We designed a simple harness testing PCB and wrote some firmware for it. Unfortunately, this board was designed on a Monday morning. Find as many bugs as you can. First submission with a score >21 gets $1000.

The amount of interactions people had with neo is crazy. The first humanoid robot to walk among us.

One of many next steps at @1x_tech: preference learning for world-model-based policies. Given a generated starting frame, we can sample multiple video rollouts from our WM and use preference feedback to steer the model toward higher-quality behavior. This lets us fix policy failures in synthetic worlds—resolving bad NEO behaviors with generated dogs before we ever meet real ones.

Done. Manufacturing is underway. My first PCB of this year. An external exhaust valve controller for my car.😇 Dual FDCAN and LIN transceivers, STM32G474 MCU core and ESP32-C3 wifi module.

Tτ@teraytech

Exhaust LIN frame captured and variations are as expected. I’m building another PCB with LIN transceivers

think it’s funny that for so many years tech mocked things like fashion, aesthetics and intuition and now it’s all “taste taste taste”

This billboard makes me pause every time I drive past it. I don't know what it means but it's weirdly effective in getting me to notice it.

As an informal research project to gain experience doing AI interpretability, I investigated the representations of RNNs trained on base addition. It turns out that they represent numbers along a helix! Here's the embeddings for a 1-layer RNN trained to add in base 10. 🧵

@randallmbriggs That looks like a Qualtec LTE module (EX25?) which usually has built in GNSS. Also it looks like there is no GPS antenna so that feature is likely not used

English

Randall Briggs@randallmbriggs·15 Eyl

So apparently while doing a teardown of the Unitree Go2 robot dog iFixit found a GPS module inside that is not listed in the official spec sheet for the robot. The robot also has a camera and microphone along with lidar. So you are trusting this company with geotagged video, audio, and 3D scans.

@MickyAbir Looks great. Are you receiving a video stream with tracks already overlayed or are you syncing the video and tracks on the ground side? And what controller is that?
