Too few sampled comments (2) to say how often HN recommends it.?

Why HN links it

Linked by one commenter for a post on running NNTP for an RSS aggregator, blog engine and ActivityPub server, and by another for a Hacker News user-age distribution chart. The comments do not judge the writing.

Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

  1. I've been recording changes to the three lists of approved first names in Denmark in git for the past 8 years: https://koldfront.dk/git/godkendtefornavne/about/ I'm using cron on my cupboard server to update regularly rather than relying on Microsoft GitHub, and a standard post-update hook that emails me the diff when there are changes, so I can check out what new, funny, misspelled firstnames have been approved. Gi…

  3. @asjo over at koldfront.dk is still using NNTP for all sorts of things (RSS aggregator, blog engine, ActivityPub server): https://koldfront.dk/just_call_me_mr_nntp_1871 Indeed, it was a lost opportunity. The protocol os easy to understand, and it plays well with decentralization as you say, and with self hosting. With Python 3.12 out, its nntplib module is scheduled for deletion/removal in v3.13. What a pity. The NN…

  5. "Horrid" is a bit harsh, but the typography choices are hard to understand, at least as rendered on my screen: * http://koldfront.dk/misc/hn/sg.png The font for the main text is oddly changing between being very thin/light and on some select letters quite fat (v, A). The links are _very_ bold, impeding reading. Other than that I think your design nice and simple.

  6. I have been using Linux as my only operating system since Yggdrasil Fall 1994. Before that I was a happy Amiga user. After Yggdrasil I took a short turn to Slackware (downloaded a lot of floppies), and then switched to Debian which I had heard nice things about - and I have been running Debian ever since. I always get surprised at how complicated other systems (Windows, Mac OS X) seem to me, when I briefly encounter…

  7. I think I tried programming initially when I went with my father to a course in BASIC at his workplace. After that we hauled a 300 baud matrix printer-like terminal home, equipped with a couple of sucktion cups for attaching the phone's handset, and a roll of paper. I distinctly remember that putting the handset in the sucktion cups quickly enough after dialing the number on the rotary phone was hard. The first real…

  8. Yes, here is a scatter plot: · http://koldfront.dk/misc/hn/pl/data.png I would like to make a bar chart with favorite votes pointing up from the x-axis and dislike votes pointing down, but my rudimentary R skills doesn't stretch that far yet.

  11. They reflect the polls, so they also tell you that the polls didn't have the same choices. The two sets of data ought to be shown in the same graph, really. Edit: I have now joined the two years in one graph, and plot the percentages to make it easy to see the change: http://koldfront.dk/misc/hn/database/data.png
