I never close my browser tabs/windows (nor restart my computer).

ORLY? Please fire up your Terminal, enter “uptime”, and share the result with us :cool:

But I also ~~never~~ seldom close browser windows and there are LOTS of tabs I never close. Like the “unread posts” here on L19 and Oooooootakomoku :-D

Grtz, Tom

In my previous Mac (where software updates were a little ness "noisy", i.e. pre-Lion, and boot time wasn't 15 seconds) I could easily rack 180-200 days of uptime. Why reboot?

I do remember uptimes of 20, 30 days with my Macs but not longer; currently I need to reboot perhaps once a day because of some weird stuff that makes trouble … but I then again I need to run stuff like Parallels friggin’ Desktop for my work, and stuff like InDesign/Photoshop/Illustrator, and perhaps too many fonts and background “helpers” <shrug>.

I guess life would be a lot easier for me if I just needed mail and a browser and number crunching. I envy you.

Well, R, a background Go process local server running, Sketch, Gimp and a MAMP stack can take a toll of my Mac, but having 8 gigs of RAM (and an SSD disk) has improved my life a lot vs having 2 Gb and a normal HDD. I don't envy people who have to use Photoshop & Illustrator

As I said before, for fuseki skill I think you need at least 25 problems before you start matching the level of the problem to the level of the user.

First of, the whole issue was most likely caused by the bug I fixed a few hours ago. That aside, there is a normal distribution prior for the rank. The lower the sample size the more the prior ends up weighing in the outcome. Hence first few answers regardless if they are right or wrong wont budge the rank too much.

Given your prior, how many straight "correct" answers does it take to get a rating with a mean of 4D? How many with only one "wrong" answer?

Thanks.

The prior is a normal distribution with mean of 5.5kyu and stddev of 5 stones. If you were to answer correctly a few tsumegos where 7dans always get it wrong, and 9dans always get it right, your mean would jump to 4dan and well beyond with only a few questions. However since the positions you are shown are those considered easy for your estimated rank, it makes it more difficult to prove strength as you wont be shown difficult enough problems to quickly prove you are 4dan. In practice I would guess around.. 30-40 problems to prove 4dan strength as it is. However proving 15kyu strength should only take about 10 wrong answers.

How about some simulations? For some representative ranks. Like 4D, 1K, 6K, 11K, 16K.

It's now possible to choose what type of problems to study at www.ootakamoku.com , with this in place I can add more pro games, since its possible to differentiate between modern and older pro games.

LuckyJim · **#148**

Options to choose from, nice!

What is the Beta option for?

It now displays a breakdown of user rank according to categories and comparison to different servers. What feature should I add next?

RBerenguel · **#152**

Since when there are NGA ranks

?

Well, the komi in our NGA games depends on the rank assigned to us by the teachers. But in truth I just put there to promote NGA just a tiny bit.

RBerenguel · **#154**

That's a good thing

I'm 5k NGA rank, feel free to add it to have a data point in there

There are around 100 unique users per day at the moment, most spending around 15 minutes on the site, some a lot longer.

I'm one of the latter, likely, since I'm trying to do ~ 100 positions each day. 100 visits day is quite a lot for a go site!

Ootakamoku WOW! This was what I got when I clicked the “go back” link “… to take a look at all the possible answers”.

Its intentional, you are the first person to see the tsumego and it doesn't have a correct answer yet. The correct and uncertain answers will be based on strongest user answers, which for the time being will be you for this tsumego, until someone stronger answers it. There shouldn't be unduly many of these, and I kinda hope it rare enough that I don't actually have to code a warning for these.

OK, hoping that stronger players provide the correct answer soon then :-)

Thanks for your reply. I think I’m also one of those who use your site 15+ minutes per day :-)

and I think it’s AMAZING! Thanks again!

I just finished calculating your rank based on your first 257 answers, but still working on the remaining ones. By my estimate your rank is between 10.1 Kyu and 7.5 Kyu. I can provide you a detailed breakdown of your rank.

Give me a second, I'll arrange the information for you... Here is your rank in different aspects of go.
Everything : 10.1 Kyu - 7.5 Kyu.
Fuseki : 10.0 Kyu - 7.0 Kyu.
Tsumego : 12.7 Kyu - 5.2 Kyu.

KGS 16k representing the SDK ranks. Also, has anyone noticed that the kgs board is really, really pale after being on Oootakamoku for a little while?
