Pruned is a personal blog at pruned.blogspot.com about design and science. Since 2010, 15 different Hacker News readers have linked it 15 times, most often “Computing Partial Differential Equations with Water”. The last post was in 2019, but the archive is still widely read.
Too few sampled comments (6) to say how often HN recommends it.?
Why HN links it
HN readers link Pruned for posts on analog computing, such as a Soviet water-based computer that solves PDEs by mapping them to hydraulic flow, and on atomic gardening.
Summarised by Claude from a sample of 6 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

HN discussionCheck out http://pruned.blogspot.com/2012/01/gardens-as-crypto-water-c... to see a Soviet water-based computer. I don't know the details of it, but it appears to be able to solve PDE's by mapping the PDE you're solving to a hydraulic system. Since the flow of water is governed by PDEs, once you've mapped the problem to the computer you can just make some analog measurements of water flow to get the answer you're loo…

HN discussionI like to bring this up whenever people start talking about not wanting GMO's. If you are brushing your teeth with a toothpaste that contains peppermint oil you're ingesting a Atomically Modified Organism or HMO every day! I prefer this article on the subject though. http://pruned.blogspot.com/2011/04/atomic-gardens.html

HN discussionThanks for the very interesting submission! The followup post ("Gardens as Crypto-Water-Computers Redux") is also great! The photo of the Fontana di Diana Efesina (Tivoli, Italy) is amazing. Looks like something from Angkor Wat. https://pruned.blogspot.com/2013/02/gardens-as-crypto-water-...
