Jim's Random Notes is a personal blog at blog.mischel.com about programming and systems. Since 2011, 4 different Hacker News readers have linked it 5 times. It is still writing: the last post was on 2026-10-12, and you can follow it by feed.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN commenters link these posts on web crawler etiquette, a crawler that deleted files, and wood density for historic shipbuilding. The commenters cite them as background rather than praising 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.
What Hacker News says?
I ran into this with my crawler, too. See http://blog.mischel.com/2008/08/08/hey-you-deleted-my-files/

HN discussionRather than emoticon-ing away your responsibility in a potential site DoS, perhaps read up on responsible crawling - https://webarchive.jira.com/wiki/display/Heritrix/Responsibl... + http://blog.mischel.com/2011/12/20/writing-a-web-crawler-pol... . You had no need for either unlimited or even 50 parallel crawl tasks. And, if your intent is anything but personal use, you shld prbly (re)read https://www.brewtoad.com/l…
