This is a little page that scrapes the APIs for Lobste.rs, Hacker News, and Reddit's /r/Programming, compares URLs for submissions, and prints a match if the URLs are the same.
I wrote it to give more depth to the discussions on Lobste.rs.
The numbers at the end of each submission is the score (net number of upvotes), the number of comments, and the comment/score ratio. The ratio is only printed if the sum of the score and comments is 10 or more.
A script is run hourly, reading the latest entries from both sites. Then the page is generated.
The SQL is basically
select lo.url from lobsters lo left outer join hackernews hn on hn.url = lo.url left outer join proggit pr on pr.url = lo.url
It only matches URLs exactly, so if there are extraneous elements in a submission to one site, it won't show up.
While the HN API offers a list of the latest 500 entries, the script
only scan the
/newest page on Lobste.rs,
and if the number of new entries manages to replace the page entirely
between reads, the script might miss entries.
The scores and comments are only updated occasionally as I don't want to overload the API endpoints.
