This long run is a personal blog at blog.thislongrun.com about programming and systems. Since 2015, 5 different Hacker News readers have linked it 11 times. The last post was in 2015, but the archive is still widely read.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
HN readers link this blog to clarify that the 'C' in CAP (consistency across replicas) is not the same as the 'C' in ACID, a terminology point that often causes confusion.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
CAP Theorem: look at consistency availability and partition tolerance definitions in distributed systems and big data databases.
What Hacker News says?
Oh, in addition to my other reply I should point out that the 'C' in CAP is not the same thing as the 'C' in ACID. Be careful with that one, it can cause confusion! http://blog.thislongrun.com/2015/03/the-confusing-cap-and-ac...

HN discussionThis post looks at the application as a whole, not only the datastore. But for an eventually consistent big data store, AP is not possible. See http://blog.thislongrun.com/2015/04/cap-availability-high-av...

HN discussionThanks for posting this to HN (I'm the post author). There are two posts: 1) the link you posted. It looks at the application as a whole, not really at the datastore alone. 2) Another one on the big data store themselves, and more generally of the different definitions of 'availability'. It's here http://blog.thislongrun.com/2015/04/cap-availability-high-av... I will update the posts to make this clearer. As well, i…
