I recently built a spaced-repetition module in learnawesome.org to help users practice and remember not just from whatever they're reading, but also by taking notes from meetings, conferences, videos etc. Wrote an article about it: https://medium.com/learn-awesome/practice-what-you-learn-usi...

Very cool! Do folks feel like there would be value in a hosted service that provides a backend for spaced-repetition apps? It's a bit niche, but feels like there would be demand for a service that would let folks build memorization apps without having to manage their own spaced repetition implementation.

I would consider this greatly valuable

With computers, which excel at memorization, why not off-load out faulty memory there? And use time, and brain capacity, for things that we are still better at, or at least at fun or fulfilling? For each prompt, my first thought was "yeah, I have it in Evernote/1Password/Google Calendar" followed by that it makes my life easier. So basically, let's embrace our extended phenotype!

The ability to quickly google a piece of information != knowing, understanding, or being able to use it in any meaningful sense.

The notion that memorization is useless or somehow not integral to the learning process is wrong. When you intuitively know an idea, you can build upon it and combine it with other ideas in a subconscious and long-term way. This isn't possible if you externalize your memory to a computer.

Hi Hackernews, I created Spacedtime because I'm known to have a horrible memory. Maybe people are kidding but I wanted to change that. There are flashcard apps out there but I wanted to create one that is focused on creating cards for my personal memories. My personal goal is to store and recall all that is dear to me. Given the personal nature, I do plan on spending a lot of my time on protecting the user's informat…

How about 3rd party storage through the users own dropbox, gdrive, 1drive. Then it's still sort of self hosted Also easy to use same data across devices. Not sure on the syncing strategy/performance

Draw.io does storage federation to OneDrive and others pretty well.

I bet you know this, quite old, quotation on memory:

"They will cease to exercise memory because they rely on that which is written, calling things to remembrance no longer from within themselves, but by means of external marks."

There is a profound difference between memorizing sequences of characters (passwords, ids, phone numbers, surnames, dates, particular APIs) and memorizing concepts (which may, but not need to, use these characters as a component).

I think it would be valuable, I've actually had this idea (but not the competence/bandwidth to actually build it, alas).

It could become a platform for courses built around SRS, or learning materials like Michael Nielsen's mnemonic media: https://numinous.productions/ttft/ .

There seems to be an unaddressed need for a well-maintained library implementing spaced repetition algorithms. I have seen implementations for SM15[0] and SM2[1][2] around but nothing that provides multiple implementations and a consistent API on top. If there was a library like that, a tool like SpacedTime could use it easily (currently it uses fibonacci sequences when determining how soon to recall). [0] https://gi…

Given that I’ve wanted to make apps for learning languages but always get lost in the weeds of various spaced repetition algorithms - would love this kind of open source resource. If anyones interested in making this kind of thing, I’d love to chip in. For example I notice it’s really common for spaced repetition algorithms to really easily allow me to shoot myself in the face by learning too much up front and then d…

What I would like, but cannot set Anki to do is the following:

Max 100 cards per day (I can set the number of reviews, but seeing a card twice counts as 2 reviews)

Max 10 new cards per day (restricted by the above limit)

I’ve found this to be a good pace when manually juggling this, but the thing is, I don’t want to manually do it, especially not on a piece of software like anki.

I was thinking on the same line, to dump all the personal memories into cloud not just anniversaries and birthdays but also what I promised to others and what I observed or any decision at work so that later I can back myself up with data. Its like a personal journal in case my memory becomes weak. There are things like evernote but they are more of a active notes which you open sometimes infront of others or while s…

Ah, promises are something I didn't think about but a great one! Can you elaborate on the time-line? What do you mean by it?

By time-line I meant any content that is put be it promises or decisions or even imp events like meeting someone new must be stored with a timestamp and can be viewed in a chronological order. Something like facebook timeline, I can jump right back to Jun 2015 with a couple of click and see what was I thinking that time. Something we used to do in a Diary which had a page for a day. This may also help reminding us important recurring event like Birthday's anniversary, insurance premium without having to explicitly look for them

Sure, that quote is from Socrates about books. I don’t think he’s actually wrong: the average person today probably is less mentally capable than ~2,500 years ago. Books are more useful as a storage device, to be sure, but externalization does have downsides when it comes to mental cognition itself.

Don’t disagree with on the sequences of characters point, though. Unfortunately most people don’t make that distinction and lump everything into the ‘not worth memorizing’ camp.
