I've been using Maxima since my undergraduate (over 10 years), now with Ubuntu20.04 lts, I become a newbie of SageMath. For a small project (both symbolical and numerical), in particular, student lab activities, Maxima has been a powerful tool for analyzing and visualizing data. (The Android version is also fantastic, but the poor keyboard.)
Mathematica is always enemy/friend. (My coworkers are all Mathematica speakers.)
Affinity Photo might be a bit more popular than Maxima. We know about 33 links to it since March 2021 and only 27 links to Maxima. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
And if you need a commercial alternative, for professional shops that need/require it, Affinity Photo is very good. Serif only offers perpetual, per major version licensing (i.e. No subscription) and offers a 'universal' licence if you use multiple platforms (Windows, Mac, iOS). https://affinity.serif.com/en-gb/photo/. - Source: Hacker News / 8 days ago

I think the really neat piece of software behind this is maxima (https://maxima.sourceforge.io/), a rather influential computer algebra system of ancient lineage still in use today in more place than you might think. - Source: Hacker News / 2 months ago
In the maxima computer algebra system[1] which was ancestrally based on lisp it has a single quote operator[2] which delays evaluation of something and a "double quote" (which acually two single quotes rather than an actual double quote) operator[3] which asks maxima to evaluate some expression immediately rather than leaving it in symbolic form.[4] [1] https://maxima.sourceforge.io/ [2]... - Source: Hacker News / 3 months ago
