chorasimilarity is a personal blog at chorasimilarity.wordpress.com about math and science. Since 2014, 8 different Hacker News readers have linked it 21 times. It is still writing: the last post was on 2026-11-02, and you can follow it by feed.
Too few sampled comments (7) to say how often HN recommends it.?
Why HN links it
HN readers link this blog for writing on chemlambda, a graph rewriting system modelling chemical and biological computing, and on lambda calculus. It also carries commentary on social media, censorship and Sci-Hub.
Summarised by Claude from a sample of 7 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
"Under Elsevier’s proposed terms, the publisher would have charged UC authors large publishing fees on top of the university’s multi-million dollar subscription" So it's a move against both traditional paywalled publishing and Gold OA. The argument that some universities refuse to pay because they are "scholarly poor" [1] is only propaganda. [1] https://chorasimilarity.wordpress.com/2019/02/28/google-tran...

HN discussionTwitter tries to cancel the Library of Alexandra. We should discuss a bit about Twitter as well, I think. In other comments I saw the resonable demand to express support for Elbakyan. Recall that we discuss about the biggest free library of research works. I tried this here: https://chorasimilarity.wordpress.com/2021/01/08/enemies-of-...

on “Sci-Hub Founder Criticizes Sudden Twitter Ban over “Counterfeit” Content”I think the discussion is a bit myopic. Yes, this is horrible news for the new aggregators of content. What about the creators of content? What if authors hodl their copyright (or else be filtered)[1] Who keeps google, facebook and others to share the original content instead of hiding it in favor of the same or worse content taken from big media or publishers? I don't stand by this extremely stupid legislation but…

on “Society Needs an Alternative Web”Very good comment! Social media companies present themselves as better (technical solutions for) commons. Their identities show this: face book, (bird) tweets... I don't want to be mean, but the actual situation makes me think that they are sort of new parasites for the commons (seen as an organism), sort of a cymothoa exigua [0] of public speech. Since a comment like yours is so rare, I tweeted it :) [1] and I plus…

on “The problem with Facebook”There was a time when I thought places like GitHub are the future of Open Science [1], which will replace paper articles by data+programs. The problem is now well-known: at any moment somebody will buy the whole place and will upgrade it, so to say. [1] https://chorasimilarity.wordpress.com/2017/04/02/the-price-o...

on “Why I no longer use GitHub (2018)”What is censoring for search results? I think is this: search for a definite term (like a site name) and get no result, where previously you got many results. This happens all the time, but is not noticeable for large numbers of people. This may be argued as acceptable when it comes to political speech (as it is the fashion these days). This is also not new at all, historically. Whenever an authority adopts or makes…

on “Google is silently censoring search results”> I want people to walk away from Twitter feeling like they learned something and feeling empowered to some degree. It depresses me when that’s not the general vibe, and inspires me to figure it out. That’s my desire Last year, in March I deleted all my tweets and closed my account [1]. A month ago I discovered that my account appears as "suspended" [2]. I don't feel empowered by this Tweeter information about me. […

on “Do you experience errors in Google Scholar?”Some numbers: There are 264 posts with animations, a bit more than 1/2 of the original collection, with the possibility to rerun in js the simulations. Whenever possible there is a mol file attached to the animation. There are about 490 mol files. If they are too big to be used without stalling the js reduction, this is signaled by the message “mol too big” in the post. If there is no mol which matches, this is sign…
