Three kinds of work, three success criteria, and why confusing them is costly. Early in my career I worked at Bell Labs, where one could work on any intellectually challenging problem, whether or n…

It comes down to utility, not NGU. Few understand. What has fiat brought you? You can use cryptocurrency instead of fiat right now. What is stopping you? submitted by /u/bitrequest [link] [Kommentare]
Are there any websites listing post-doc job opening in machine learning? Currently I'm using LInkedIn to search for these. When I was a math post-doc, everyone used "MathJobs.org" to find jobs. Is there a similar website for machine learning? Thanks. submitted by /u/random_sydneysider [link] [Kommentare]
I'm building an autonomous rover using ROS2. For mapping, I'm using SLAM Toolbox, and my goal is to navigate the rover autonomously. My rover uses BLDC hub motors (the type of wheel in the picture) that have built-in hall sensors. However, I'm confused about how to generate the /odom topic required by SLAM Toolbox using these hall sensors. From what I understand, SLAM Toolbox needs odometry data, but I'm not sure: How to convert hall sensor readings into wheel odometry. How to calculate wheel position, velocity, and robot pose from the hall sensor data. Whether hall sensors alone are accurate enough for odometry. If there are any ROS2 packages or existing solutions that can help with this. Has anyone implemented odometry using BLDC hub motor hall sensors in ROS2? Any examples, tutorials, or advice would be greatly appreciated. submitted by /u/Organic-Author9297 [link] [Kommentare]
In bad shape - took a loan to buy more crypto and stupidly didnt sell high at the 2025 bull. Someone, anyone.... tell me we will see new ATH inside 1 year? Just make it feel better lol submitted by /u/13toros13 [link] [Kommentare]

Instead of just watching videos or apps, this system uses a dual-arm gantry with five-finger robotic hands that: - Precisely control each finger’s position and pressure on the keys - Use compliant (flexible) actuators for natural-feeling guidance instead of stiff pushing - Start with strong support and gradually reduce assistance as you build real muscle memory It turns passive learning into active, embodied practice — helping you feel the correct movements directly.
