    • 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).

    • Ask HN: Best Open E-Reader?

      Kobos[1] and Pocketbooks[2] are a lot more open than Kindles. AFAIK you can transfer .epub files into both devices and these epubs are perfectly readable via the stock OS. If for some reason you find the stock proprietary OS lacking, you can install an open source one like KOreader [3] or Plato[4] Of course you want a good way of organizing epubs pdfs mobi, and like has already been mentioned Calibre[5] is a great…

    • Kindle AND books?

      Sure thing – another must-have resource if you get a kindle is good library management software. Assuming you download books instead of purchasing them directly from Amazon. The gold standard is Calibre eBook manager (windows and Mac, 100% free). Using it, you can sideload books to your device using a cable or email.

    • Is the pocketboom era the right choice for me ?

      You might want to use Calibre on your PC to manage your library, it is entirely free and a fantastic piece of software. It also can convert eBook formats very well, also the abovementioned AZW format or KFX format, and with plugins, it can even remove copy protection.

    • Has anyone used Humble Bundle to buy books for the Remarkable 2?

      Calibre can convert the file, and if you install the right plugin it can apparently upload the file to your tablet as well. I haven’t tried the plugin, so I can’t really talk about how (or how well) it works, but from the Github repo’s README page it sounds like the author isn’t maintaining it on a regular basis anymore. I’m fine with uploading files using the built-in web page anyway.
