Bug in the answers site
(I tried to use the feedack form, but it doesn't seem to work. If this is redundant, please let me know, and I will delete it. And I think it would be better for you to delete it after you acknowledge the problem, because it doesn't belong here)
I think a feature of the software that runs this answers site is actually a bug - It seems that if one's answer gets accepted, you receive 15 pts. So far, OK, But if the OP changes the accepted answer to another, it only takes out 5 pts from your karma. It may seem logical to keep some of the karma, because at a given moment in time, the answer seemed to be perfect. But the trouble starts when you switch accepted answer multiple times - every time it happens, you add (15-5=10pts).
You can see it here, on my profile http://answers.opencv.org/users/197/sammy/?sort=reputation
15 0How to enable vectorization in OpenCV? (6 mins ago) (Accepted again. 15pts again!!!)
10 0How to enable vectorization in OpenCV? (6 mins ago) (An upvote)
0 -5 How to enable vectorization in OpenCV? (16 mins ago) (Dis-accepted. Still keep 10 pts)
15 0How to enable vectorization in OpenCV? (16 mins ago) (Got accepted. 15pts )
10 0How to enable vectorization in OpenCV? (16 mins ago) (Upvote)
I think you should be happy with that ;-)
Definitely :) But I was trying to be fair.
Sorry for all those acceptance and dis-acceptance. I was trying to mark both your answers as correct ones. It took me some time to understand that this is not possible - browser allowed me to choose both answers as correct. Only after refresh I saw that accepting another answer automatically dis-accept first one.
it was a good thing to uncover that dreaded bug :P
And by the way this is not the only bug. Some badges awarded much before their conditions are meet. For example I have badge "Notable question" which should be awarded for a question with 2500 views (last week its was 250 views). I got it after 25 views. I guess there problem with number of zeros :).
