Show HN: An ultra-light-weight tool to quickly test your ping Howdy HN! I find myself testing my ping from time to time, especially when my internet seems wonky while WFH. It feels like there should be an easier way test my ping than puling up a terminal or a complex web app - especially when I'm on my phone or any other device that doesn't have a terminal. I figured I should be the change I wish to see in the world and created this super light ping test. I also created a latency monitoring solution ( https://ift.tt/Px4WIuh ), feel free to clone and try it out! I know there are a lot more mature monitoring solutions out there, but I never did figure out how to set them up. This one is super simple: clone it to some device that's always on, compile it, set up some systemd stuff, and it's ready to rock on port 8180! https://ift.tt/g19pIDy October 2, 2022 at 02:01AM

Show HN: Sksql a Database Engine in TypeScript Hi! I wanted to understand more about databases' internals so I wrote one from scratch. It has a T-SQL inspired syntax with support for functions and procedures. It can be used stand-alone as a SQL engine or with a server allowing for persistence and replication to other connected clients. Performance are nothing near sqlite of course but that's beside the point. It’s a small database engine that can run in a web app as a way to store session data, do small calculations on a web worker, store the document/data the user is editing or facilitate “multiplayer” feature by broadcasting the queries the web app is running. The server runs in a container for that specific document and shutdowns automatically after a set amount of minutes of inactivity. https://ift.tt/BZ8oczw October 1, 2022 at 09:24PM
