Show HN: A *really* easy to use C++ server-side Node.js Monero miner Hi Guys. Last weekend I bootstrapped a little side project. Its a really really easy to use NPM module, that loads XMRIG (c++) and starts mining.I just released the first version on the NPM registry. It can be setup to only run on production machines (NODE_ENV production). It can be used on CI/CD setups where the machines do nothing for a long period of time it can be used on simple webservers that do not have a lot of traffic. Etc etc It writes output to a log file, to the console, or totally ninja mode and no output is given. It even includes a simple webview to monitor stats. By default its set to 'low priority', so the machines doesn't freeze up! :) Let me know if anyone is planning on using it or has any problems, thanks! https://ift.tt/3p4dkos https://ift.tt/3Ec87Sc November 29, 2021 at 07:33AM

Show HN: Security Camera Lens Calculator ( www.jvsg.com/online/ ) We created Security Camera Lens Calculator with 3D graphics(WebGL) and a built-in camera database. Calculator functions: - calculate pixel density (PPM/PPF) - clearly see dead zones in 3D - check DORI zones (detection, observation, recognition, identification) based on pixel density calculations and IEC and EN 62676 standard. - calculate lens focal length - load a floor map to see camera coverage on your plan - over 9,000 video surveillance camera models embedded in the CCTV Lens Calculator. - the calculator can be used on a tablet, PC or a smartphone. - 12 languages supported. Today we launched our Security Camera Lens Calculator also on ProductHunt. We would love to get some feedback. Particularly from people using it to solve real world problems.
