Hi,
I've made a quick recipe to get the latest
weekly edition of LWN.net on my kindle. It will fetch the latest current edition if you enter your lwn credentials and have a current subscription; failing that, it will get the latest free edition (usually a few weeks behind).
I have some Python experience but this is my first try at a Calibre recipe, feel free to comment if you see a better way to do things.
Cheers,
Davide
