Karma Code

[OscarVanL]

Hi,

I'm a little intrigued as to how the Karma system works - it says on my profile (oscarandjo) that it takes 4 hours before new deals show up, but this is slowly decreasing. However, I could not find the code on here.

There is an explanation on the website but thought it was a bit vague.

Could you please explain the system and how I make more karma, other than referring people?

Thanks.

Hi

I updated the code so you should be able to see how it works. By visiting pages you get 10% of your page_karma_quota moved to your karma. You get a default karma of 5. Every night the following get executed on the system: cursor.execute("UPDATE users SET page_karma_quota = '1'") cursor.execute("UPDATE users SET karma = karma * 0.99") cursor.execute("UPDATE users SET karma = 5 WHERE karma < 5") This resets your quota to 1 and you decay 1% of your karma which saturates at 5. The delay you have is 60 hours / karma. Doubling karma halves your delay. When you refer others, you get 50% of any karma they get.

That's helpful :) Is there a maximum amount of karma you can earn in one day from browsing the site?

[brejc8]

Yeah, 1. So even if you max that every day, once you reach 100 karma, you will decay as much as you receive. To give you perspective, each day there are on average 18 active users each day.

Thanks for the helpful explanation. Is there a limit of 15 somewhere in the code? I can't seem to get my karma above 15 but I see no limit of this in the code.

[brejc8]

There is no limit at 15. It looks like you had 14 yesterday, so it will not reach more than 15 in a day, and you will lose 0.15 tonight and be able to get up to nearly 15.85 tomorrow.

Hi all. Just realized that the daily maintenance scripts have not been running because of a typo in the cron. This explains why your karma was stuck and unable to go up. Sorry about that.

Thanks for figuring this out. Thought I was going crazy. Keep up the good work!
