m1el is a personal blog at m1el.github.io about programming and security. Since 2015, 11 different Hacker News readers have linked it 20 times, most often “The Most Expensive Anti-Pattern”. The last post was in 2021, but the archive is still widely read.
Too few sampled comments (5) to say how often HN recommends it.?
Why HN links it
HN commenters link m1el's woscope pages on oscilloscope-style vector graphics and the jsonht page on representing DOM trees as JSON. They are cited in threads on XML, JSON, DOM libraries and vector rendering.
Summarised by Claude from a sample of 5 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

HN discussion> JSON for lists, XML for trees No. JSON is a recursive data structure that can represent trees as well. It's easy to make a concise representation of DOM trees as JSON: http://m1el.github.io/jsonht.htm I find it really sad that people don't know or consider s-expressions to represent trees.

HN discussionI have had great success using the ideas presented here ( http://m1el.github.io/woscope-how/index.html ) for simulation of traditional vector graphic screens. It is very fast and easily modified to allow for intensity modulation as well.

HN discussion> I was playing with the idea of using JS objects as a template engine: http://m1el.github.io/jsonht.htm , and I'm pretty happy with it. Isn't that the same as (among several other things) React's JSX?

HN discussionI was playing with the idea of using JS objects as a template engine: http://m1el.github.io/jsonht.htm , and I'm pretty happy with it. I think DOM is pretty damn fast in modern browsers. `innerHTML` can be slower than creating elements from a JS object! Here's the script I'm using for timing: https://gist.github.com/m1el/b28625b3b9261f0fab819e866133e49... My results in Chrome are: dom: 2663.580ms, innerHTML: 10999.4…

on “Reverse Engineering Might and Magic III Compression”There is another bug I think we must get rid of: generating HTML using printf techniques. Not only we should have verified parser, but also verified serializers. http://m1el.github.io/printf-antipattern/ (EDIT: I know it is badly written and there are errors, but, I'm looking forward to rewriting it)
