Show HN: Dak – a Lisp-like language that transpiles to JavaScript Hi HN, author here. Happy to answer any questions. I had an itch to make a lisp like language that was a thin layer on top JavaScript. Something that could leverage the thriving ecosystem that exists around JavaScript. It's brittle, hot off the oven. Besides being a fan of parenthesis, I think macros fill in a gap that the JavaScript ecosystem today fills in with one-off compilers, bundler plugins and such. Macros can't do everything, but for example I think they have the potential to enable things like JSX, Solid and Svelte style libraries. Take the tour to get a feel for what it can do and play with the live code in your browser! https://ift.tt/VRoiwLb February 27, 2023 at 06:08PM

Show HN: Collect and search robotics data with SensorSurf We've been building SensorSurf and are thrilled to share our beta with the robotics community: https://ift.tt/1ZJ2eAm . SensorSurf is an open source platform that makes it easy for robotics engineers to collect and search data from their fleet. You can define triggers for when to record data (e.g. emergency stop) and capture the moments leading up to the event with rolling buffers. We integrate directly with ROS. Drop our agent into your system, and start collecting data! ================= What prompted me to found this company: > I was a perception engineer working on autonomous boats. > I needed tons of imagery to build computer vision datasets. > It was impossible to offload all this data over satellite. > I interviewed robotics companies, and learned this was a common problem. ================= Our beta enables you to: 1. Trigger recording on arbitrary ROS topic data. 2. Capture the data leading up to the tri...
