  • Conversion from epub to kepub, and related Calibre use
    I only read kepub files on my Kobo Clara 2E (kobo stock). I use KOReader to read PDF, CBZ (comic files) and epub. Source: 5 months ago
  • First E-reader. I am thinking of buying Kobo Libra 2?
    You can easily modify it (like adding KOReader). Source: 5 months ago
  • Calibre – New in Calibre 7.0
    It doesn't try to solve the same use cases that Calibre does, but I built an open source (EPUB only) manager / reader / statistics tracker called AnthoLume [0]. It mostly stemmed from me reading in KOReader [1] on my Kindle, and not having the ability to sync the progress to my iPhone / iPad. It's got metadata matching, support for multiple users, and statistics tracking which allows me to have a "Leaderboard"... - Source: Hacker News / 5 months ago
  • Show HN: News2reader – Readable articles from HN and Pocket on your e-reader
    Hi! I recently became the owner of an e-reader, and wanted an easy way to get web articles from Hacker News and my bookmarks onto the device, on-demand, for easy reading. I'm using KOReader (https://koreader.rocks/) on my device, and like lots of e-book readers it allows browsing online catalogs of books (e.g. From sources like Project Gutenberg) using the OPDS protocol. News2reader is a self-hosted Node... - Source: Hacker News / 9 months ago
  • Is the pocketboom era the right choice for me ?
    No I don't have any special lag. But I also don't use the default reading app, I use Koreader. I think the normal reading app also doesn't have much lag. Most modern eReaders have much less than 5s lag. Source: 10 months ago

  • What do software do you use to create flashcards when reading ebooks?
    I did find this https://getpolarized.io/ But it seems that project is dead. Source: 5 months ago
  • Show HN: Lurnby, a tool for better learning, is now open source
    Https://getpolarized.io/ seems like it's in the same space - it's a product I wanted to love, but was a bit clunky to use and didn't end up sticking in my workflow. - Source: Hacker News / about 2 years ago
  • How do you memorize things you read?
    Don't think Anki has a fully baked implementation of incremental reading. Polar [0] is an interesting implementation of a similar concept: read and annotate and turn your highlights into Anki flashcards automatically. [0]: https://getpolarized.io. - Source: Hacker News / over 2 years ago
  • Want to Remember Everything You'll Ever Learn? Surrender to This Algorithm
    Https://getpolarized.io This is a tool meant to help with incremental reading, with support for generating Anki flashcards. - Source: Hacker News / over 2 years ago
  • How to Read Books When You Have ADHD
    “Some books are to be tasted, others to be swallowed, and some few to be chewed and digested; that is, some books are to be read only in parts; others to be read, but not curiously; and some few are to be read wholly, and with diligence and attention.” -- Francis Bacon Mortimer Adler's How to Read a Book provides a decent framework for dealing with the variety of books out there. There are also tools like Polar[1]... - Source: Hacker News / about 3 years ago
