lucassus / bayesian rating
Created June 6, 2018 06:18 — forked from latompa/bayesian rating
bayesian rating
-- building on data from my scenario http://gist.github.com/44489
-- and bayesian rating http://www.thebroth.com/blog/118/bayesian-rating
assume we have a products table and we want to sort products based on their rating.
With bayesian rating, you get better weighting, so that a single 5 star vote won't show up as "top product"
select * from products;
mysql> select * from products;
+------+--------+---------------+--------------+---------+
| id | name | ratings_count | total_rating | weight |

ruby-1.9.3-p286 cumulative performance patch.

Patched ruby 1.9.3-p286 for 30% faster rails boot + with support of utf-8 console input

What is?

This script installs a patched version of ruby 1.9.3-p286 with patches for boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.

Huge thanks to funny-falcon for the performance patches.
