Show HN: DRS-VPT. Localize a photo in a 3D point cloud without an initial pose

Hi HN, I work on multi-modal sensing for robotics.We built DRS-VPT to estimate a camera's 6-DoF pose in a 3D map from a single photo and a 3D point cloud, without an initial guess or known camera intrinsics.The interesting part is generalisation: the same model works across driving LiDAR scans (KITTI, nuScenes), iPhone photos in indoor scans, and SFM maps.We provide the code, model and weights, but you can also try it out at https://huggingface.co/spaces/fulkast/drs-vpt-demoHappy to answer questions about the method or its limitations!

Show HN: RealtimeVAD – trading false positives for 110ms earlier end-of-speech

Hey guys. I recently watched the latency reports for my local voice assistant, which show a waveform plus silero probability for voice activity. I noticed silero lags visibly on the speech off signal.There had to be a method to get this signal closer to what I felt is optimal. My idea was to use a 10 ms energy detector with a threshold that adapts to environment or room noise. Which worked amazingly well. It created more false positives but in my speculative generation pipeline that would not matter. If it's wrong and the user continues speaking I can abort the pipeline fast.I benchmarked my solution over ~3200 turns from my assistant logs and it came out ~110 ms faster initially. Still 100 ms now after some a fix which was needed for quiet speech.I made it public if you want to have a look. If you measure it on your data I really appreciate any feedback. There's a benchmark script in the repo.Thx for reading, have a good day folks. Comments URL: https://news.ycombinator.com/item?id=50474586 Points: 2 # Comments: 0

Four layers of context engineering for production AI agents: How Deep Insight applies them in working code

In production AI agents, context management is the real bottleneck. This post presents a four-layer context engineering framework (architecture, prompts, file-based tools, and verification agents), implemented in working code from Deep Insight, an open source multi-agent data analysis solution on the Strands Agents SDK and Amazon Bedrock AgentCore.

Show HN: Using GPUs for other bs than AI – important prime record for the geeks

Hey HN, if you want to be new prime gap hero here is the code that runs and gets you biggest merits (everyone knows what that is in prime world). I spent months to tune it, and in the last few days got couple of top 10 records just by testing. So get you precious GPU time, run the code and become world no 1 in prime merits because it will make you cool, just not to your friends, girlfriend or family. Help the geek cause!
