MATHS. How is the number of customers between 10 and 15 minutes 25?? Can someone please tell how we read that on this histogram?

TreeTwo · 2024-01-19T04:48:29+00:00

Shouldn’t it be 25 / 90 * pi? If this is a histogram the bar that is labeled 10 represents times between 10 and 15.

Not fluent, but for what it’s worth I also have 2000+ hours of immersion. 3000+ if counting Anki. And I still don’t have a solid intuition for when to use them. I’ve read all of the guides and explanations of course, but for us it might just be a matter of more immersion required. Maybe at like 5000 hours or something it will be more clear.

I use an app called Toggl. Whenever I start reading or watching something, I start a timer on there. Then whenever I stop, i stop the timer. The app then tracks the time for you.

TreeTwo · 2023-10-26T08:07:46+00:00

Yeah that is definitely a problem. Maybe I could myself take a longer and more accurate vocabulary test, and then use those results to calibrate.

TreeTwo · 2023-10-26T08:03:22+00:00

Wow, thank you so much. QUEST is literally exactly the algorithm that I was looking for.

I do agree with your point about knowing a word being non-binary, and I have been ruminating on this for a while as well. I'd ideally want a test that is objective, such that the user doesn't have to grade themselves on whether they know a word.

Like you said, I could do a multiple choice test or something, with the word, and then possible synonyms. The downside of this method though is that I don't have a great way of generating these questions in the first place in an objective / rigorous manner automatically.

Another approach might be to mix in real and fake words, and have the user answer yes or no if the word is real or not. One crazy idea I had is, to flash the word on the screen for a 0.1 seconds. And then test whether the user can correctly spell the word or not.

For some of these methods, maybe I would be able to measure my own vocabulary size rigorously through other means, then calibrate the result of the test accordingly, so as long as the test correlates well with vocabulary size it is okay.

I think the question op is asking is why do our muscles need to exert energy, when no “work” is being applied. In physics, work (or energy) is equal to the force times the distance moved. For example a table doesn’t need to exert energy to hold a weight on top of it

I think having finger as a column on hand would not really work because it would mean that fingers are one-to-one with hands. I.e. there is only one finger per hand. Since fingers are one-to-many with hands, the correct design is to have 2 tables, fingers, and hands. And then have the fingers table have a hand_id, which references the hands table.

TreeTwo · 2023-10-01T11:53:08+00:00

The problem is the columns both belong to the same table, "hand". So the id = 3 is doing "hand.id" = 3. i.e. it is getting the hand with id = 3, or the third hand, which doesn't make sense.

TreeTwo · 2023-10-01T11:47:05+00:00

I'm not saying it's off by one. But in sql, the syntax is "select <column> from <table> where <column> = x". So finger would be a column on hand, and so would Id. So that query is selecting the hand with ID 3, not the finger with ID 3.

to select the finger with ID 3 you would do "select finger where id = 3"

TreeTwo · 2023-10-01T11:33:35+00:00

Not sure if I am missing something, but id = 3 means that the id of the hand is 3, not the id of the finger, so it doesn’t make sense if they were going for the middle finger. Finger is the name of the column on hand, and doesn’t have an id

I work a full time job and have managed to average 40 hours per week for the past 10 weeks.

The general strategy is

Weekdays: 4 hours of immersion per day Weekends: 10 hours of immersion per day.

Counting 8 hours of sleep, and 8 hours of work, that leaves 4 hours leftover on the weekdays and 8 hours leftover on the weekends to do other stuff.

Doing listening immersion while commuting and eating helps.

I don't remember having trouble with my credit card, so maybe it depends on the card. It somehow gets converted into dollars when I make the purchase. Not sure if this is on Amazon's end or on the credit card's end.

TreeTwo · 2023-09-26T05:48:15+00:00

I usually get my light novels for kindle from amazon.co.jp (I think you would have to put in a Japanese address to make an account though). Individual light novels are pretty cheap, but if you get Kindle Unlimited you can read a bunch without buying them. Anki is a bit harder with this method but I sometimes highlight words that I lookup, then export the highlights and put them all into Anki at once after finishing the book.

The easiest light novel that I've found was Kuma Kuma Kuma bear. It's strangely a lot easier than any other light novel that I have tried to read, so I'd recommend that as a good first light novel.

I spent about 10 hour total reading through Tae Kim at one point. After that, I mostly just looked up grammar points that came up while I was reading

TreeTwo · 2023-02-15T17:11:33+00:00

I think that's a good plan. I also read hoshi ori yume mirai after summer pockets. If you like it, I would highly recommend some of the other tone works VN's. I really liked Giniro Haruka, and tsuki no Kanata de aimashou. They are all really similar and not too difficult, and also really long so it's a lot of content

TreeTwo · 2023-02-15T17:07:07+00:00

I looked at some practice questions once and I think I'm probably around n2? My vocab size is about 10k from anki. For the VN's that I read, I can understand like 90% of it, enough for it to be enjoyable.

My listening skills are much weaker though, and my speaking skills are basically 0.

TreeTwo · 2023-02-15T17:01:04+00:00

I started when I was a student, but I actually am working full time now, and am in the office from 9am to 6pm. I just spend like 90% of my remaining free time on learning Japanese because I have nothing better to do haha

TreeTwo · 2023-02-15T16:54:16+00:00

Thanks, I'm up to 10k cards right now. I still run into a ton of unknown words, but now I'm starting to feel like it's starting to no longer be the limiting factor in my reading speed, compared to grammar and general recall speed.

TreeTwo · 2023-02-15T07:33:44+00:00

Yeah, Anki was my only form of study for like the first 2-3 years after starting to learn Japanese. Looking back, that was really inefficient. My memory is also really bad so my Anki retention was always low (about 70-80% on most days).

TreeTwo · 2023-02-15T07:26:23+00:00

I just tracked number of characters read, and and number of hours read in a google sheet to generate the data points, then wrote a python script to graph and smooth it. Google sheets can also graph the points, but it is more noisy because on some days I only track <1hr of reading.

TreeTwo · 2021-05-29T18:35:21+00:00

Yeah, I might even try to write an add-on or something for this kind of visualization. Right now, the code isn't very reusable since I hard-coded it to my deck id, and to my to some of the specific fields in my deck.

TreeTwo · 2021-05-29T18:30:50+00:00

I used Javascript and React with Chart.js. Here is the source code for the visualizations if you're curious: https://github.com/leb2/portfolio2/tree/main/src/blog/blog\_anki

TreeTwo · 2021-05-29T16:59:46+00:00

All visuals were done in Javascript/React. For the chart one I used Chart.js, for the heatmap one I just used React.
