What it does
chartsrv is a dead-simple web application which runs Prometheus queries and charts the result as an SVG. You make a dashboard by putting a lot of these images into a web page. You make it refresh by adding <meta id="refresh" http-equiv="refresh" content="5"> to the header. Ta-da! Forward /chart.svg to this address with your favorite reverse proxy. If you want to listen to some other port, pass a second argument like :1337 . Create a URL like https://chartsrv.example.org/chart.svg?query=...&args... and set the query parameters asfrom sr.ht

Minimalist library to generate SVG views of scientific dataMar 2026 · github.com · ▲47Just wanted to share with HN a simple/minimal open source Python library that generates SVG files visualizing two dimensional data and distributions, in case others find it useful or interesting. I wrote it as a fun project, mostly because I found that the standard libraries in Python generated unnecessarily large SVG files. One nice property is that I can configure the visuals through CSS, which allows me to support dark/light mode browser settings. The graphs are specified as JSON files (the repository includes a few examples). It supports scatterplots, line plots, histograms,…

Almost eight years ago I launched an online “Linux sysadmin course for newbies” here at HN. It was a side-project that went well, but never generated enough money to allow me to fully commit to leaving the Day Job. After surviving the Big C, and getting made redundant I thought I might improve and relaunch it commercially – but my doctors are a pessimistic bunch, so it looked like I didn’t have the time. Instead, I rejigged/relaunched it via a Reddit forum this February as free and open - and have now gathered a team of helpers to ensure that it keeps going each month even after I can’t…
