    If I make the environment variable persistent in my .profile, Calibre's ebook reader does not work. - Source: dev.to / over 1 year ago
  • All Kindles can now be jailbroken
    I suspect most people that go this route (ie download and manage their own ebooks, then transfer them to their Kindle) use Calibre, which afaik, is unaffected by this change. https://calibre-ebook.com/. - Source: Hacker News / over 1 year ago
  • From RSS to My Kindle
    Very neat. I've been doing this with Calibre (https://calibre-ebook.com/), which involves plugging it into your PC via USB. Simple RSS feeds work with little configuration, and more complicated news sites require writing a custom python "recipe". This project uses Amazon's email gateway, which I think is limited to 25 articles per month (don't quote me on this). - Source: Hacker News / about 2 years ago
