For my money Calibre is one of the most indispensible pieces of software in GNU/Linux. It can handle all your e-books in all the major formats, including PDF, EPUB and Mobi. It supports up to thirty e-reader devices but this article will tell you how to use Calibre to convert RSS feeds to EPUBs (which can then be read in Calibre's own E-reader or synced and transferred to your external reader of choice).
Despite what the Calibre webpage says about not installing from distro repositories, this really is the easiest way to do it and it should be in all the major distros. So, once installed start it and let's get cracking. By default, Calibre come preloaded with RSS feeds that you can convert to EPUBs but we're going to create a customised one and we'll try that with FSM.
You should now be looking at Calibre's main interface. Select
Add a custom news sourcefrom the Fetch News button.
And you wiil be presented with three fields to populate.
First, open FSM in your browser and click on the RSS feed in the location bar.
and then copy and paste the URL into Calibre and give the feed and recipe a name too.
Schedule news download expand the
custom category and click on FSM. Now, choose
Download now. Calibre will download and do the necessary EPUB conversion. Hit Save and you're done.
You will now see FSM in the Cover Browser (if you have it enabled, Highly recommended) but as you can see from the screenshot, because Calibre could not find a contextual cover it loaded its own default cover image.
We can fix that by selecting
Download Metadata and covers from the Metadata button.
From the resulting screen click on
Browse and select an image from your hard drive.
And, finally, we have the finished product!
Click on it and read FSM articles in the built-in EPUB reader.
