Show HN: 3D Topography of Your GPS Track As a hiker and (ski)mountaineer I've always been a bit disappointed of how most apps fail to properly depict the topography while analyzing GPS tracks. (I know that Strava offers some kind of 3D view by now, but I still wanted to build my own thing) That's why I started working on https://cubetrek.com It's still very experimental, but you can give it test-drive now. Any feedback appreciated. It essentially renders your GPS Track as a 3D model within the topography. As an example, here's the Bishorn, a 4000 m peak in Switzerland: https://ift.tt/39VFXPo The front end is based on Babylon.js, D3.js, the back end is Spring Boot and Postgresql with PostGIS. There's a summary on how it works at the very bottom of the homepage. https://cubetrek.com August 5, 2022 at 07:57AM
Show HN: Launch VM workloads securely and instantaneously, without VMs Hello HN! We've been working on a new hypervisor https://kwarantine.xyz that can run strongly isolated containers. This is still a WIP, but we wanted to give the community an idea about our approach, its benefits, and various use cases it unlocks. Today, VMs are used to host containers, and make up for the lack of strong security as well as kernel isolation in containers. This work adds this missing security piece in containers. We plan on launching a free private beta soon. Meanwhile, we'd deeply appreciate any feedback, and happy to answer any questions here or on our slack channel. Thanks! April 29, 2021 at 07:50AM
