A new open-source project called openGym, published by developer DuarteSantos8, is drawing interest online. The JavaScript tool lets gym-goers self-host their own workout tracker: planning routines, logging sets, supersets and cardio, and visualising which muscles are trained, fatigued or detraining. It supports imports from popular apps like FitNotes, Strong and Hevy, plus passkey login, appealing to users who want their fitness data on their own server.

Edward Tufte's data-ink ratio, a long-standing principle in data visualisation that urges designers to strip away non-essential ink from charts, is being examined and explained in a new write-up that aims to clarify what the concept actually means and how it should be applied. The discussion has drawn attention from the design and data community, where the principle remains influential but often debated.

A developer is adding new functionality to the Chart View feature of their software, while acknowledging mixed feelings about the work. They say they are not a believer in charting and note that many existing programs draw better charts, but still see value in visualising data, remarking that a picture paints a thousand words. The update is being shared openly as work in progress.

Kepler-1314 b is a Neptune-like giant exoplanet located 463 light-years from Earth. Discovered in 2016 by NASA's Kepler telescope, it has a radius about 5.11 times that of Earth and completes an orbit in just 5.42 days. Astronomy communicators are sharing the planet's profile alongside NASA's Eyes on Exoplanets visualisation, drawing renewed attention to the Kepler mission's catalog of worlds beyond the solar system.

A new write-up examines Edward Tufte's well-known data-ink ratio, the principle from 'The Visual Display of Quantitative Information' urging designers to maximise the ink devoted to data and strip away chart decoration. The piece reframes the idea as 'Tufte's Razor' and walks through what the ratio actually measures and how to apply it in practice when designing charts and visualisations.

Developers are discussing a technique for streaming charts where data changes every second. Instead of the costly route of rebuilding markup or redrawing a canvas on each tick, the approach uses st-core alongside CSS to update visualisations without re-rendering the DOM. Commenters in the open-source web development community are sharing the method as a lighter-weight option for real-time dashboards and monitoring tools.
