Rob Bell's personal blog at rob-bell.net covers programming and career. Since 2009, 10 different Hacker News readers have linked it 10 times, most often “A Beginners’ Guide to Big O Notation”. No feed was found, so read it on the site itself.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
Linked as a reference for Big O notation and how loop and algorithm growth rates scale. Commenters cite it to explain the concept rather than to praise the writing.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

HN discussionIronically, big-O describes things that are very easy to understand, in a notation that looks complicated. If you have a lot of experience, you probably already understand the concepts. The notation just gives a clear way to describe them: https://rob-bell.net/2009/06/a-beginners-guide-to-big-o-nota... ,

HN discussionIt's not a dumb question, this idea is covered at the beginning of every data structures class and is described as Big O Notation. The difference is the growth rate. for(..){} for(..){} will grow linearly, or O(n). Iterating over 10 items will be 20 loops, while iterating over 11 items will only be 22 loops. for(..){ for(..){ } } grows exponentially, or O(n^2) Here iterating over 10 items will be 100 loops, and incr…
