Wish: "Read it later" plus "spaced repetition" app for language learners

Update: found something close enough:

Wish: "Read it later" plus "spaced repetition" app for language learners

  • All the usual ways of sending articles to this "Pocket" app: email, browser extensions, the app itself.
  • While reading, select word of phrase, have it translated and added to app as a flashcard. Front: word/phrase highlighted in context; Back: translation + optional notes.
  • Batch mode: toggle batch mode, select multiple words/phrases, have their definitions/translations all added as flashcards.
  • Optionally, go through those new cards right away (as opposed to studying them only in the random-ish order of the whole set's spaced repetition) and, when finished, go back to text. This way you can quickly go through a paragraph in batch mode, mark everything you don't understand, study it, then go back to read it with the necessary vocabulary.
  • When not reading, user can go through flashcards with a spaced repetition algorithm and interface similar to Brainscape's. From

Putting the "Tor" back in Torrent

Putting the "Tor" back in Torrent

How a Popcorn Time fork patch could incentivize people to run thousands of new Tor relays

This is a follow-up to this discussion: Can NAT traversal be Tor's killer feature?

If torrents are P2P's killer application, and NAT traversal/"static IP" are Tor's (via hidden services), putting them together could prove to be the best incentivization scheme for growing the Tor network other than cold crypto cash.

You're stupid

Everybody knows you're not supposed to use torrents with tor, right?

Can NAT traversal be Tor's killer feature?

Can NAT traversal be Tor's killer feature?

tl;dr: how about a virtual global flat LAN that maps static IPs to onion addresses?

[We all know the story][1]. Random feature gets unintentionally picked up as the main reason for buying/using a certain product, despite the creator's intention being different or more general. (PC: spreadsheets; Internet: porn; smartphones: messaging.)
