Show HN: Cubic Doggo, a Open-Source 12-DOF 4-Legged Robot Based on ROS2 This is a recipe for building intermediate-priced robot dog from scratch with all commercial/3D-printed parts, controlled by Rasp Pi 5 and ROS2 Jazzy. A manually coded walk gait is implemented so far, which can be controlled by a controller to move forward or change directions. It does not yet have an IMU required for RL training; however, I believe it's one of the simplest design out there available for multiple development paths. https://ift.tt/fYChoxq May 18, 2026 at 10:50PM

Show HN: drea – podcast ad blocker https://ift.tt/LAVMQZJ

Show HN: drea – podcast ad blocker Always been annoyed by podcast ads. Searched and found a few apps that can detect and skip them, but they were all paid. So I made a free one. To my knowledge this is the first podcast app with free ad block. iOS (26+) only for now. If the app becomes popular I'll def think of doing an Android version as well. The app doesn't require a user account. I may open-source it at some point; still thinking about it. If anyone's suspicious about how it's able to be free, i.e. doesn't it cost money to run, are you selling my data (I'm not) etc. I'm happy to explain in the comments. From a technical perspective, the innovation here is ad detection despite dynamic/programmatic ads, which is the norm in most popular podcasts these days. There is ofc a naive way to do it, but it's expensive and high latency. There is also an even simpler way but it's illegal lol (re-host and serve just one version of the episode). I was able to ...

Show HN: How to Kill the Dead Internet https://ift.tt/trnCSV0

Show HN: How to Kill the Dead Internet Ok, so maybe "how to revive the internet" would be more accurate, but if you're reading this, I got your attention, right? Here's why I want you to read on: I built a free extension, D-slop, to disincentivize anyone from posting AI writing, and eventually images and video as well, on the internet. For writing, it checks known vocab and punctuation tells, as well as subtler tells related to cadence, and assigns it a score subject to an adjustable threshold. If the text fails, users have the option to flag offending text, hide it, or block the page entirely (with the option to see anyway). For media, it's admittedly fairly weak, as it relies on C2PA metadata which is stripped from all of the social media sites where it would be most helpful. (Anyone else have chronically online boomer parents continually gobbling up slop like it's real information?) I have a D-slop+ version in the works that should be able to handle the med...
