Show HN: Mini Metroidvania in 13KB of JavaScript As part of the annual JS13K games challenge, I've put together a pretty large (but small-in-code) Metroidvania game that fits in just 13KB of compressed Javascript. The source is available here: https://ift.tt/UR8DpwZ NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github. Useful hacks: - Using Roadroller ( https://ift.tt/rnbivK1 ) for compression - Compressing the map data as grayscale PNG paired with some code generation. - Using procedural animation for all characters. - Replacing string enum with numeric enums for compression. - Built a small game engine for object lifecycle and rendering. - Single function to generate unique procedural songs for different regions. https://ift.tt/9wpYcHb September 14, 2022 at 12:25AM
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
