Filtering Hot Questions from the StackExchange Network

The Stack Exchange network of sites receives a lot of activity everyday, and certain sites get rather interesting questions. These questions are classified as "Hot". This repository allows one to subscribe to a filtered feed of these hot questions. So you can receive these "hot" posts by email based on your interests. The official feed just dumps all the questions which might not be desired.

Usage

The server simply returns a feed, filtered based on the query parameters. You can use the version I am running on http://se-hnq.awalgarg.me, or run your own server (see instructions below).

You can filter the feed as follows:

http://se-hnq.awalgarg.me/?include=math

This returns a feed containing only hot questions from http://math.stackexchange.com. You can filter by tag as well:

http://se-hnq.awalgarg.me/?include=math:calculus,limits

This returns a feed containing only hot questions from Math.SE which are tagged calculus or limits.

You can add multiple such rules separated by |:

http://se-hnq.awalgarg.me/?include=math:calculus,limits|codegolf

This returns questions from both codegolf and Math.SE with the specified tags.

The same can be applied in reverse as well, using the exclude parameter.

http://se-hnq.awalgarg.me/?include=scifi&exclude=scifi:star-wars

This returns only hot questions from SciFi.SE which are not tagged star-wars.

Setup

This is written in nim, and has no dependencies. Simply compile with:

nim c hnq.nim

And run the compiled executable, passing the port to run the server on as the first parameter.

./hnq 8081

Why nim?

Was just trying out the language. It seems quite nice.
