It’s unclear—do you mean that the number of points received for posts gets multiplied by 10, both for positive and negative votes?
Yes an up vote on a post is worth 10 karma points to the contributor, a down vote −10 points.
With regard to discussion, I just implemented what I was instructed to do.
Hi ciphergoth, I’ve made some changes this morning that make the Less Wrong code base compatible with PostgreSQL 8.3, which is available in the karmic repositories. The change is on the ‘postgres-8.3’ branch in git. I have run through and revised the Hacking on Less Wrong wiki page this morning on an Ubuntu 9.10 install and have confirmed that it works. It would be great if you could have another go at getting the code up and running and let me know how you go.
