SQL to update pathes for modules with multisite drupal installation

Problem: 

Modules was setted up for one site from multisite drupal installation. So we have it installed in /sites/test.com/modules/ and that pathes we have in system table in DB. Now we need to see them on other site for example test.org so all pathes should be /sites/test.org/modules/.

Solve:

UPDATE `system` t, (
SELECT REPLACE(filename, 'test.com', 'test.org') as test, name as name, type as type
FROM `system` WHERE `filename` LIKE '%test.com%') AS t2
SET t.filename = t2.test
WHERE t.name = t2.name AND t.type = t2.type

Authcache - detailed documentation

Authcache is drupal community contributed module you can find here Authcache project page. The Authcache module offers page caching for both anonymous users and logged-in authenticated users. This allows Drupal/PHP to only spend 1-2 milliseconds serving pages, greatly reducing server resources. Please note that enabling authenticated user caching will require modifying how your user-customized content displays on your pages. You should be an experienced Drupal developer if you choose to implement the full functionality of this module. Anonymous caching won't require any changes and will offer a speed improvement over Drupal core since hitting the database can be completely avoided.

Authcache Installation

To install authcache module you need

1. Download authcache module and extract it to drupal contrib modules dir (usual /sites/all/modules).
   
   
   

Continuous Integration - Drupal way. Part 1 - Begining.

Motivation:
   I'm going  to grow quality of products we get  in company I working in.
   I'm going to make ability to show bugs free product when client what.    (functionality that marked "done" realy 100% done)
   I'm going to make code clear and developement process managing.
   I'm going to make regressive testing cheap.
   I'm going to remove trivial round things from my live.

And you?
Are you going to do the same?

CI will help us. I think you know what is CI and what goals it allow to reach. (If no, you can read about CI here).
This is the first article about CI in drupal development practice.
Goal of that articles is to describe architecture of CI system and disscuss it's effectivity.
I'm going to create CI infrastructure that will be easy to use on practice of drupal development.

Here is the plan:
1) Ant build scenario.
2) Hudson configuration.
3) Code quality control - Copy/Paste reduce and Code style.
4) Drupal Simple Test and CI.
5) Selenium and Drupal Simple Test module.
6) Effective build configuration.
