> For a given word you should have the definition and the forward and reverse translation. Perhaps for simple/beginner words. But for more advanced words, it's important to realize that our active vocabulary is necessarily much smaller than our passive vocabulary. There are many words we can recognize but can't immediately synthesize ourselves on demand just from an idea or concept (or a translation, even). For anything beyond the most simple words, I think that having the reverse translation doesn't make a whole lot of sense and can be pretty counterproductive in developing one's passive vocabulary.

  In fact, the opposite is true. Something that is harder to deal with paradoxically is learned faster long term. Look for papers on "desirable difficulties". Best to memorize from L1 to L2, although neither provides an opportunity to acquire the language so make sure that you are only using it as a bridge to help you comprehend native input. Get as much native input as you can. Free reading is usually the easiest way to do that.

    For listening comprehension, radio and podcasts are great. Some state broadcasters even produce dumbed-down content (such as news broadcasts with simpler vocab, read slowly and clearly) in their country's language, specifically for non-native speakers.
- kazinator 7y ago
  In addition, reverse translation is a 1:N problem. Many cards from the foreign language to yours have recurring words on the back: if you reverse that, you will often have to remember many different foreign words for one card. Then how do you judge whether you know the card? 4+ out of 5 is good?, 3 is "hard", 1-2 fail?
  - 0815test 7y ago
    > if you reverse that, you will often have to remember many different foreign words for one card. This is one of many, many reasons why spaced-repetition systems should support dependencies - as in, "delay card X until after cards A, B, C have been solidly learned." Then you'd just gradually learn a sequence of reverse cards for that one word: most common first, then second-most common (prompted as: "<word> (2)"), third most-common and so forth. With each "depending" on the previous cases in the sequence.

      The Wanikani (paid) spaced repetition software does exactly this for learning Kanji. It's exceptionally well thought out, both in order of dependency and frequency. I'm currently using it, and I love it. I still use Anki for vocabulary, but wish there was something as polished as Wanikani instead.
      - kazinator 7y ago
        I made a (paid, freemium) program (for Windows) called Tankan for memorizing kanji that is very efficient. Much more so than spaced repetition. http://www.kylheku.com/tankan/ http://www.kylheku.com/tankan/ In Tankan, instead of viewing flashcards, you take batch tests, typing answers into blanks, tabbing from one field to the next. The machine grades your answers as a batch, and you can take a new test immediately over just the unanswered/incorrect items. As you gain proficiency, a "pipeline" process takes over: your eyes can read ahead two or three kanji while your fingers basically don't stop. I've been able to review some 1200 characters in the space of about 40 minutes of furious typing, when my accuracy on those characters hit around 96%. Instead of spaced repetition, once you're proficient, you can just fire this up once every few months, and just review every kanji you know in one short, sweet little session and be done with it.

Some interesting ideas, but why are question and answer cards better than Cloze cards? A recent blog post (https://senrigan.io/blog/everything-i-know-strategies-tips-and-tricks-for-spaced-repetition-anki/ https://senrigan.io/blog/everything-i-know-strategies-tips-a..., https://news.ycombinator.com/item?id=19831526 https://news.ycombinator.com/item?id=19831526) suggested Clozes were better. Neither one provided much reason to believe what they said.
- vezycash 7y ago
  In my experience, the first cloze option should be something easy to guess. For example, take the text: The sun rises in the east and sets in the west. The sun rises in {{c1::the}} {{c2::east}} and sets in the {{c3::west}}. Since the first card is easy to guess, the cloze card effectively becomes the tutorial. It makes it easy for people to use cards made by others.

  To prepare for the FAA instrument written and oral exam component of the checkride, I built an Anki deck (https://ankiweb.net/shared/info/2105122272 https://ankiweb.net/shared/info/2105122272) with the following principles in mind, all of which favored cloze cards. * Effective learning: Twenty rules of formulating knowledge https://www.supermemo.com/en/articles/20rules https://www.supermemo.com/en/articles/20rules * Anki Guide for Medical Students https://drwillbe.blogspot.com/2011/08/anki-guide-for-medical-students.html https://drwillbe.blogspot.com/2011/08/anki-guide-for-medical... * How to make high quality Anki cards quickly https://managingmedicine.org/2013/05/14/how-to-make-high-quality-anki-cards-quickly/ https://managingmedicine.org/2013/05/14/how-to-make-high-qua... * Anki Tips: What I Learned Making 10,000 Flashcards http://rs.io/anki-tips/ http://rs.io/anki-tips/ By default, Anki will show you only a few cards per day.

I love anki, but I really don't like the code. I wish we could build something modern, but still open, from scratch.
- burtonator 7y ago
  Play with Polar for a bit and let me know what you think. This is sort of the idea but Anki is still pretty amazing in a lot of ways if you're a power user. I'm trying to make SR easier for people just getting into it. For me the frustration was switching back and forth between my document reader and Anki. I wanted something completely integrated.
- DiogenesKynikos 7y ago
  Could you be specific? What are the problems with the codebase? I've found that as a user, there are some really powerful features in Anki. The distinction between notes and cards wasn't clear to me at first, but once I discovered it, it allowed me to create some really useful decks. Being able to create multiple cards, with HTML and CSS styling, testing various elements of the same note is really nice.
  - burtonator 7y ago
    Some of it has to do with the code base but some the UI. Anki sync is slow, often requires full re-sync. I also don't like how a lot of the core functionality has to be implemented via plugins. This is being too negative though. Anki is great. Nothing is perfect. It has a lot of features that nothing else out there has. It's kind of like an old and reliable battleship that can't be sunk. (I mean this in a good way).
  - thepete2 7y ago
    It's too tightly coupled, doesn't really follow best practices and is barely documented. When I wanted to improve it, it just wasn't very inviting :/ Fully agree with your 2nd paragraph though
  - Shorel 7y ago
    The fact that `sudo apt install anki` doesn't work out of the box is enough of a problem for me. Ok, the install works, but the software never runs. This is one of the reasons my laptop is booting into Windows more often than into Linux these days.
rgrieselhuber 7y ago
Polar looks really cool but it looks like there isn’t a self-hosted version? I’m basically done with cloud data i don’t control (as much as possible...)
- burtonator 7y ago
  I'm sympathetic to this and we'll be bringing up a version in the EU and also adding E2E encryption at some point. Just not sure of the schedule at the moment. Right now though you can use it on a local disk and do a git commit of the whole thing: https://getpolarized.io/docs/git-sync.html https://getpolarized.io/docs/git-sync.html The downside is that you have to restart every time. I'm not going to do inotify due to scalability issues I've had with it plus Windows/Linux/MacOS differences are going to kill me. If you're using the cloud version (in the future when we have encryption plus the EU datacenter option) it will also support partial sync which git doesn't support now. This way you can keep just the most recent 500MB on disk. Also, Polar is OSS so I'm anticipating others writing Filecoin, S3 and other backends in the future.

    - sundar4344 7y ago
      I don't understand. To my knowledge HN does not have ads. Are you saying users posting polar news repeatedly is being considered as ads ?
- arkades 7y ago
  I ... surprisingly agree. I generally am in favor of creators on HN sharing a new product with Show HN, or in threads when it’s relevant to what’s being discussed. Hell, when I’m happy with a product, I’ll be the first to chime into the thread and share my satisfaction. I have different feelings about Polar. Maybe because it repeatedly gets front page every time Anki/SRS comes up, which isn’t rare. Or maybe it’s just because when I tried to use it to expand my Anki deck with peer reviewed papers, I found it unbearably inconvenient / difficult, -plus- it insists on being yet another privacy-invading cloud offering for a product for which cloud involvement feels forcibly tacked on. Quite disappointing, since this product really solves a problem for me. I guess the combination of “how badly I wanted to like and use this product” + “how disappointing it was in use” + “how frequently it’s on the front page” adds up to seriously being sick of seeing Polar ads.
dhandel 7y ago
Nice, and open source. Bravo and congratulations. Such a nice step beyond bookmarking webpages. I have created https://idorecall.com/ https://idorecall.com/ a web app (soon to work in mobile browsers too). Unlike Polar, you upload your learning files (Word, PPT, PDFs and image files as well as videos on Youtube) into iDoRecall and read them there. If you see a concept that you comprehend or a fact that you want to remember, create a spaced-repetition flashcard (we call our RECALLS) linked to that fact/concept. Then when you practice your RECALLS, if you forget an answer, click a link and the original source file/video opens at the exact linked location where you created the RECALL. Refresh your memory and quickly get back to your practice session. I wrote a few weeks ago about my life experience that led me to create iDoRecall: https://medium.com/better-humans/how-to-unlock-the-amazing-power-of-your-brain-and-become-a-top-student-369e5ba59484 https://medium.com/better-humans/how-to-unlock-the-amazing-p...

Macross8299 7y ago
These are some great tips! Been looking for something similar to this app to help create anki decks directly from documents, kudos. A sidetrack but are there any good resources on using Anki for learning mathematics? Google brings up a lot of varied and conflicting info. I know nothing is a substitute for working through proofs yourself but surely flashcards can help with memorization of proofs and theorems?
- Smaug123 7y ago
  Have an anecdote from me, who spent four years at Cambridge learning maths with Anki. Anki is peerless for learning large numbers of very small facts. I found it very unsuited for learning relatively small numbers of large facts like entire proofs. The best way I found to use it was to select one or two key, short, intuitive (informal) milestones within each proof, and use Anki to associate the theorem statement with those milestones. Any larger unit of memorisation just didn't work for me - took too long to learn, made it a miserable slog to get through the repetitions, and so on. Convert things to lists, where each element of the list is small, and you have a much better chance. I did once try and learn a proof of the three Sylow theorems by means of a 50-card Anki deck, assembling a linked list of the stages of the proof; but even a single sentence of proof can be more mathematically dense than really lends itself to Anki, and I would probably redo it with fewer cards and more intuitive steps (relying on my mathematical ability to fill in the gaps dynamically). If you want to learn long formulae, I got some success out of setting them to music. I learned the various differential operators in polar coordinates this way, to avoid having to rederive them every time I needed them. (As an aside, I learned Hard 'n Phirm's "Pi" song almost by accident, which got me nearly 150 digits of pi.)
  - james_s_tayler 7y ago
    My experience attempting math with Anki was similar even though it was just a few undergrad papers. It can still have its place, just it won't get you nearly as far as it gets you when learning a language or history or other more easily digestible things. It's exactly as you say. Small, quick to review facts. Anything else makes reviews unbearable. In a somewhat related experiment I'm trying to use it to learn codebases. Important classes, outline of code paths etc. It's challenging. It sort of works and sort of doesn't. I'm finding a similar thing to how you mention learning milestones in a proof. Kind of memorizing hints that can help you rather than full sequences of things.
seieste 7y ago
The data policy of Polar is unacceptable to me. I’d like to be able to read PDF’s without third party connections to multiple sites, which Polar seems to do. I once spent part of an afternoon looking at where I’d need to remove analytics, only to find that there are so many places that it wasn’t worth my time. Further, some of the dependencies have their own google analytics tracking, which makes Polar a minefield of privacy issues. I think the idea of the software is great in theory, but I just can’t justify constant phoning home when I can easily read PDF’s through any other (privacy-respecting) PDF reader.
blasterjeff151 7y ago
With all this talk of Polar, I want to mention the tool Weava as a great annotation tool. I use it all the time as a way of annotating web content and PDFs. It has a beautiful aesthetic. No integrations with Anki yet as far as I'm aware. (I have no vested interest in the software, I'm just a big fan.) http://weavatools.com http://weavatools.com

These are some great tips! Been looking for something similar to this app to help create anki decks directly from documents, kudos. A sidetrack but are there any good resources on using Anki for learning mathematics? Google brings up a lot of varied and conflicting info. I know nothing is a substitute for working through proofs yourself but surely flashcards can help with memorization of proofs and theorems?

Have an anecdote from me, who spent four years at Cambridge learning maths with Anki. Anki is peerless for learning large numbers of very small facts. I found it very unsuited for learning relatively small numbers of large facts like entire proofs. The best way I found to use it was to select one or two key, short, intuitive (informal) milestones within each proof, and use Anki to associate the theorem statement with those milestones. Any larger unit of memorisation just didn't work for me - took too long to learn, made it a miserable slog to get through the repetitions, and so on. Convert things to lists, where each element of the list is small, and you have a much better chance. I did once try and learn a proof of the three Sylow theorems by means of a 50-card Anki deck, assembling a linked list of the stages of the proof; but even a single sentence of proof can be more mathematically dense than really lends itself to Anki, and I would probably redo it with fewer cards and more intuitive steps (relying on my mathematical ability to fill in the gaps dynamically). If you want to learn long formulae, I got some success out of setting them to music. I learned the various differential operators in polar coordinates this way, to avoid having to rederive them every time I needed them. (As an aside, I learned Hard 'n Phirm's "Pi" song almost by accident, which got me nearly 150 digits of pi.)

  My experience attempting math with Anki was similar even though it was just a few undergrad papers. It can still have its place, just it won't get you nearly as far as it gets you when learning a language or history or other more easily digestible things. It's exactly as you say. Small, quick to review facts. Anything else makes reviews unbearable. In a somewhat related experiment I'm trying to use it to learn codebases. Important classes, outline of code paths etc. It's challenging. It sort of works and sort of doesn't. I'm finding a similar thing to how you mention learning milestones in a proof. Kind of memorizing hints that can help you rather than full sequences of things.

The data policy of Polar is unacceptable to me. I’d like to be able to read PDF’s without third party connections to multiple sites, which Polar seems to do. I once spent part of an afternoon looking at where I’d need to remove analytics, only to find that there are so many places that it wasn’t worth my time. Further, some of the dependencies have their own google analytics tracking, which makes Polar a minefield of privacy issues. I think the idea of the software is great in theory, but I just can’t justify constant phoning home when I can easily read PDF’s through any other (privacy-respecting) PDF reader.

With all this talk of Polar, I want to mention the tool Weava as a great annotation tool. I use it all the time as a way of annotating web content and PDFs. It has a beautiful aesthetic. No integrations with Anki yet as far as I'm aware. (I have no vested interest in the software, I'm just a big fan.) http://weavatools.com http://weavatools.com
