Nations of the world, lift up your heads! For KhatzuMemo has been updated. These are the new features:

• Edit Item Fix
  My webhost recently upgraded to a newer version of PHP, and so some of the code involved with page transitions had to be updated. You may have noticed that you were enable to edit items from a question or answer page. That has now been fixed.
• Item Warning
  By design, an SRS shows you items on which your performance is weaker, more frequently. But sometimes your performance on an item is so bad, that it’s actually just wasting your time; this usually happens when you’ve added an item that is too long, too complex, or not well thought out enough (remember that an SRS is not a substitute for learning or memory techniques, it’ll help you to not forget, but only if you’ve gotten — remembered — the item in the first place). Such items are called “leeches” in SuperMemo terminology. In KhatzuMemo you now get a warning about them, and some suggestions as to what to do [delete or rethink].
• Number of Repetitions/Retention Calculation
  …is now more accurate than it was before; it’s now calculated directly rather than indirectly.
• Repetition History
  This is a behind-the-scenes thing that won’t really come to light until more detailed item statistics are being displayed, but, the repetition history is now being kept to a higher accuracy (date and time) than it was previously (date only).
• Swap Question/Answer
  This is just a little feature that lets you switch the question/answer fields without going through the trouble of going to the Edit page. Note that it is an editing feature rather than a display feature. I’m not so sure about adding it, so if it turns out to be less than useful I may scrap it :).
• Longer, thicker, harder! 30% Less Fat!
• Et cetera!

We will fight them on the beaches!

So…a feature that was annoying a lot of people was the whole “make you do an item a kajillion times over” plan. That has now been changed, so that if you get an item wrong, even if it gets set to be re-tested on the same day (rather than at a later date), it will go to the “back” of the stack of items for that day, so that you get tested on other items before you get re-tested on the original failed item.

The second and feature that has been removed is the annoying \”backslash action on quotes.

Big thanks to everyone who shared their opinion on these features and suggested more desirable behavior.

Friends, Romans, countrymen. I’ve had isolated reports from some people of KhatzuMemo not working on their phones. This is serious, not least because KhatzuMemo is all about…working on people’s phones.

So for the purposes of helping everyone out, if you use, have used, or have tried to use KhatzuMemo on your cellphone, please, by way of comment on this post, let everyone know the [provider], [make and model] of the cellphone you use. Here is an example of how you might do it.

[Softbank][Sharp 904SH][OK]

In the case that KhatzuMemo doesn’t work on your cellphone, please feel free to share that information, too. Like so:

[Provider][Make and model][NG][symptoms, e.g. “login page fine, but afterwards blank”]

“OK” is for if it works. “NG” (no good) for if it doesn’t. If it doesn’t work, describe, if you can, what happens.

Peace in our time! KhatzuMemo has been updated.

It’s not a pretty, user-interface update, it’s in the nuts and bolts behind the scenes. The repetition scheduling algorithm on KhatzuMemo has been modified to take into account more of the extensive data that get collected with each repetition of an item. I’d found that there was a problem whereby repetition scheduling on some items was prematurely optimistic — over-extension of interval. Now the interval is normalized, taking into account cumulative score, mean score and lapse ratio for a single item.

Anyway, the executive summary is — it’s the best KhatzuMemo repetition scheduling yet. I’m very proud of it and you should see a steady rise in your retention rate because of it.

Hey! So, I’ve put up example sentences in “sentence starter packs” before, but, I don’t think any of those were actually sentences that I had personally used before. Just to give you an idea of what life is really like on the streets of my SRS, here are some examples of sentences that I’ve entered over the past few days.

Hello! So…there are a lot of features that need adding on KhatzuMemo, and it’s time at least some of them got added. My time management skills at this point are still at the level of “do one thing at a time” [which, ironically, is about the same level they were at 3 years ago when this Japanese thing started, hence “all Japanese all the time”, because “some Japanese as much as possible” didn’t work for me and now I’m rambling…]. So, I’m planning on devoting the next 2-4 weeks to programming rather than adding any new articles. If nothing seems to come up, I haven’t disappeared; I’m just coding :)…4649ne!
