Not to detract, but there was an article on SRS that I think I came across on HN about 2-3 months ago (though I guess may have been Reddit); I've been struggling to find it for the last month or so.

It was a fairly long article, probably a 20-30 minute read, dark background (though I guess this may have been dynamic since I was reading at night), with a broad overview of SRS, several studies cited, and a personal anecdote from someone with somewhere around 10k cards that the author reviewed daily.

I wish I could remember more details. I've combed through my browser history in all browsers (desktop and mobile) and have tried a few site-specific timeframe-limited searches with no luck. Does this article sound familiar to anyone? It was a good read and somehow I failed to pinboard it.

I don't recommend allowing Anki items to have an interval of over one year because the crude SM-2 algorithm does not capture the per-item effect of exponential decay in memory. Multiplying interval lengths by per-item ease factors is suboptimal and not the same. Unlike, for instance, ACT-R, which unfortunately has no good publicly available user interface. A good implementation of a neural memory fact model will trac…

Problem is it seems you're then throwing under the bus all those items you recall perfectly well that have 6+ year intervals, which don't require yearly review. Arguably, you could just retire those; but then sometimes they lapse, as I noted: how do you decide what to retire?

Build a knowledge graph of associative memories, measure their strength, and prune clusters with excessive memory strength

I was anti-memorization until I went back to graduate school for mathematics. I had forgotten (or never learned) a lot of things needed to pass qualifying exams. At some point I ran across the spaced repetition idea (maybe from the Wired SuperMemo article [0]) and I gave it a try. I ended up using it to memorize large portions of baby Rudin and Munkres' Topology, as well as some algebra and a bunch of qualifying exam…

I'd be really interested to see some research into integrating spaced repetition into our actual education system. Almost everything I see about it is adults learning, I wonder how much we could speed up primary school education considering so much of the "base" stuff needed to advance is rote memorization anyway seems like countries should be investing money in this, potentially trillions in unlocked economic potent…

No research here, but I use the great Fresh Cards app (by allenu here on HN) with my daughter's homeschooling, and it works great. We've used it for phonics and all sorts of basic math facts, and I use it for scheduling spelling word review as well. We're about to start teaching science and I anticipate using it a lot there as well.

>You learn that lunch is "almuerzo" in Spanish, but is it learning or just memorization/association? To me the lines are blurred, even at first sight of the word. I think there's a difference. "Almuerzo" -> "al muerzo", I know "al" means "the", from Arabic, I look up the etymology, the "muerzo" is from Latin "morsus", from which we get "morsel" in English. Mnemonic: "the morsel". Then I can guess that the form of the…

It is interesting from a linguistic point of view, no doubt, and I am an amateur etymologist myself, but let's look at reality with honest eyes: apart from a very small group of people, languages are not learnt, and learnt effectively, starting from the etymology up. I know it is almuerzo, I use it 20 times, and it is "mine". I think we should try, and I include myself among those who have an approach to learning tha…

This is language dependent. For learning Chinese, recognizing radicals (like waht represents water, and what represents tree) can go a long way in helping recall of both meaning and pronunciation. Then moving on to learning Korean, where Chinese characters make up ~25% of Korean words, recognizing the Chinese character, then recognizing the typical phonetic alterations to Chinese pronunciations, can go a long way in helping recall of both meaning and pronunciation.

What's https://www.supermemo.com/ then? I just signed up to give it a go (requires CC #, but free for a month). Still haven't found good spaced repetition vocab learning site that works well for me.

https://super-memo.com/ is the software that's being talked about.

The top-level comment links to a wired article which actually references the paid language learning tool.

Based on the mention of auto-dark-mode, probably. We put some effort into thinking about how to do dark mode right and integrate with system settings - your usual website hack of an invert toggle is wrong, but the correct auto/light/dark tri-state toggle is not obvious.

Do you have a link to that research that claimed 20-30% of medical school students use SRS?
