TIL -- I thought serif was generally supposed to be easier to read. How is this kind of thing studied, and what kind of outcomes suggest "easier to read"? Speed? Recall? Subjective? What proportion of the population are we talking about, roughly? Is it even enough that one should consider providing both a serif and a sans version of their content? Serious question.

Worldwide, at least 10% of the audience (but depending on your specific demographic, much higher) which is a crazy significant number (for contrast: your users are three times more likely to have some form of dyslexia than they are likely to be using Firefox). For anyone with (partial) dyslexia the serifs are information-murder. https://www.bdadyslexia.org.uk/advice/employers/creating-a-d... But also note that font s…

Thanks for the response and link! I'll see if I can find some primary literature on the topic -- I'm interested in how such a thing is studied! Accessibility is certainly one of my many weak points.

Great article? I'm curious what your Anki settings are, if you've changed anything. I'm pretty new to the app, but when I hit things like "you'll need see this card in 5 years" I had to dive into settings and start tweaking stuff. I'm more concerned about definitely remembering it in say 12 months than having too high of a load. But there are many adjustments to achieve this, so any thoughts?

I use Mochi with all settings out of the box. Mochi doesn't even implement the SM-2 algorithm, it just applies a multiplier to the review interval on getting it right/forgetting.

Other software which have nailed spaced repetition (and a much better UI than Anki): - https://www.duolingo.com/ (language learninig) - https://www.chessable.com/ (chess) - https://readwise.io/ (book highlights) - https://examarly.com/ (test prep) - https://app.bestudious.io/login (certifications - CFA) - https://magoosh.com/ (vocabulary)

At Math Academy ( https://mathacademy.com ), we implement spaced repetition in combination with a knowledge graph consisting of several thousand math topics and tens of thousands of connections (and growing). We're working on a post that explains how this all works technically. We have a Linear Algebra course ( https://mathacademy.com/courses/linear-algebra ) that some of you might find interesting given how often th…

Hi,

Given that SRS is a long-term endeavour, going on several years, I'd balk at paying $49/month for your app. Maybe $60/year, but your current pricing is really hard to swallow.

I've started working on my own code specific flashcard program. The algorithm, app, and cards are one part of the app, and the other part of the app -- the actual cards -- is whatever application you want.

Basically, I wanted a flashcard app mashed together with repl.it. At first I thought I'd just have the python interpreter built in, but I slowly realized that correctly implemented flashcard is a programming template and a correct answer, and that your choice of interpreter should produce the correct answer given your input.

---

So now I've come to the general formulation of the app:

Question -> Some application specific file. For Python it might be the boilerplate into which you insert a nested list comprehension. For C# it could be a whole project boilerplate into which you insert your LINQ statement.

Answer -> The expected output when your program is done executing. Probably on STDIO? Maybe something else. There are lots of IO options in an Linux OS.

Card -> Question, Answer, Executable (we could probably infer this from the "question" card)

---

Everything after this would be pretty much like Anki as it is now. You could have a script that listens to you play a song and then scores your performance. You could take touch/writing input and score penmanship. And so on.

The possibilities here are limited by your imagination.

Unfortunately, I got derailed trying to sort out the review algorithm. If anyone has any ideas on this front, I'm all ears. I know Anki's algorithm punishes skipping review days, and I'm one who skips review days frequently. Which leads to me quitting altogether because the review load becomes boring and unbearable.

Thanks for the great article, you've inspired me to take another shot at making a habit of learning through spaced repetition! I had a question: how much time do you typically spend on this activity in a day? Do you have tips for how to adjust based on the time you have available?

It depends, after a big burst of adding flashcards I'll have a big hump to get through for like 2 or 3 weeks. That might be hundreds of flashcards a day, that can take 15-20 minutes.

Right now I haven't added many cards in a while so it's more like 30-50 cards a day. Usually not even 5 minutes.

I wouldn't recommend doing hundreds of cards a day, especially if you're just getting into it. I'm just nuts.

>A common failure mode (and I did this more than once, before I got the hang of it) is to use Anki for two weeks, then drop it, and pick it back up six months later only to find you have 600 cards due for review. This is not encouraging, and it defeats the point of spaced repetition, which is to review the cards on the intervals the algorithm chooses. >I don’t have much advice in this area, except that if you have pe…

The way I did this was I added a daily task to my todo list to do spaced repetition.

And I started small. Add a few flashcards, review. Don't add more than 5-20 cards per day (Anki and Mochi have new card limits to enforce this for you).

If you use it daily, and add cards at a slow trickle, they won't pile up and you won't get discouraged.

What papers or data out there support spaced repetition? Has its support weathered the replication crisis?

Spaced repetition has a very long history with hundreds of papers published on the topic. Here's a good survey of some of the published research https://gwern.net/spaced-repetition#background-testing-works

>it doesn't even really make sense for you to make flash cards. ideally they could be contextually created based on what you're viewing It does matter. You shouldn't train on a flashcard until you have learned the idea. The computer doesn't know if you actually learned what you read. Making the flashcard based on your own understanding is an important part of encoding the memory -- it's an active process, rather than…

It's well established in communities that use Anki a lot (like language learners) that someone else's pre-made decks aren't as effective as making your own. This is indeed a usual claim. But given a reasonably good pre-made deck, I doubt it's universally true if you factor in the time it takes to make the cards. I'm learning Chinese vocabulary with a pre-made deck. I devote 20-30 minutes per day (have been doing so f…

I'd argue vocabulary is a special case. There's not that much going on. There really isn't a concept graph involved.

General advice for spaced repetition is to make flashcards atomic i.e. as small as possible, as in the OP, but general advice for language learning is to always learn words in context instead of on it's own, for example in example sentences. Have you figured out a solution combining those two goals?

For language you might be interested in the Clozemaster[0] approach. Basically, you are shown a sentence, both in English and the language you want to learn, and one of the words in either one is a cloze deletion, e.g.: English: there are thirty days in April. French: il y a trente ___ en avril And you have to complete the cloze with "jours". The sentences are compiled automatically from Tatoeba[1], the cloze deletio…

This is very nice.

For language I've always used the sentence in target language (the one i want to learn) in the front of the card and the translated sentence in the back of the card but I've always wondered if it should actually be the other way around.

Your suggestion with the cloze is another good approach
