Roman Leventov's personal blog at leventov.medium.com covers programming and science. Since 2021, 6 different Hacker News readers have linked it 8 times, most often “How can software engineers help to build climate solutions?”. The last post was in 2023, but the archive is still widely read.
Too few sampled comments (4) to say how often HN recommends it.?
Why HN links it
HN readers link this Medium author's posts for a comparison of open-source OLAP databases (ClickHouse, Druid, Pinot, TimescaleDB) and for excerpts on software estimation and Monte Carlo methods.
Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
I recommend the book "Software Estimation: Demystifying the Black Art" (2006) by Steve McConnell. Nice collection of excerpts: https://leventov.medium.com/excerpts-from-software-estimatio... There is also a short chapter on estimation tools using e.g. Monte Carlo simulations. One tip which is relevant here and that is also more or less presented in the article and probably obvious :) "TIP #65: Don't treat the output…

HN discussionIt is interesting how people love this detailed comparison, but in the same time when this article https://leventov.medium.com/comparison-of-the-open-source-ol... was posted many times on HN, it didn't receive any attention.

HN discussionFor us, a significant reason was the ClickHouse cloud-hosted offering, rather than having to manage a cluster ourselves. Their use of S3 as the backing storage medium means that large-scale data retention is quite affordable. A good comparison we've referenced: https://leventov.medium.com/comparison-of-the-open-source-ol...
