oorb VS hackernews-personal-blogs

Imagine my surprise to see OpenOrb, the standard open source software package for orbit determination and minor planet propagation, on the front page of HackerNews. Its interesting software with a beautiful theoretical basis in Bayesian statistics, and a gnarly Fortran codebase - I can’t wait to see the discussion!

Oh.

It’s one thing to land near a name in use. It is quite another to take it directly!

Mostly Python and Fortran. See for example https://github.com/oorb/oorb.

The hardest problems are always the social ones. How do you get uptake of a new method, how do you get funding, how do you politely tell a collaboration they are doing the wrong thing, etc.

But if you mean pure technical stuff - the hardest problem I had to solve was rethinking some of the inner loops of the THOR algorithm. The problem was essentially to speed up a Hough transform in 6D space. Lots of time spent profiling CPU cache timings to get that fast.

Someone compiled this a while ago which is a pretty good starter list for content discovery: https://github.com/outcoldman/hackernews-personal-blogs

I've imported most of them into https://app.recessfeed.com/ and found some nice ones to follow through that

I didn't know about your project and used https://blogs.hn

What's also helpful to get the feeds directly to your RSS Reader: https://github.com/outcoldman/hackernews-personal-blogs

However, I also needed to put some work into it and remove some blogs, because they're written in a foreign language or just not that interesting for me.

The list of HN users personal blogs is quite good:

> I was looking at your HN OPML file on GitHub [0] and noticed that the `xmlURL` and `htmlURL` attributes are the same for each entry; the `htmlURL` currently points to the feed rather than the site. Do you happen to have the original HTML URLs available? Would be nice to have both. (Secondarily, I'm guessing some of the `type` attributes should probably be "atom" rather than "rss"?)

I'm just using the file that someone else made, but I guess they didn't really make the distinction between those URLs in the code, though it shouldn't be too hard to modify: https://github.com/outcoldman/hackernews-personal-blogs/blob...

It is also true that there are both RSS, Atom and possibly other feed types mixed in there. What I did for my site was to crawl through all of those feeds and process them one by one: get all of the posts, do some ordering and grouping and output everything as RSS feeds.

For example, here's the top 100 user feeds for 2023: https://hn-blogs.kronis.dev/feed-top100.xml

Those have HTML links for each of the posts, though I'm afraid it's not exactly what you're asking for (the HTML URLs for the sites/feeds themselves), because I don't actually store that anywhere in my case.

Added a note https://github.com/outcoldman/hackernews-personal-blogs/tree...

I checked yours, the issue is that you are escaping + in application/rss+xml, when it should be just application/rss+xml

I have updated the code and will re-generate. I am not sure if what you are doing is allowed or not.
