To make Mobile Tools work with mobile sub domain, there are some tricks. Say, you want to have www.example.com for the full (desktop) site, while m.example.com is for mobile.

In that scenario, set the Mobile Tools settings as follows.
- Mobile URL -> m.example.com
- Desktop URL -> www.example.com
- Enable automatic redirection -> On (checked)

<meta property=”og:image” content=”your image url here”/>

In the header section, choose PHP code filter for the input format, then write the following.

<?php global $language;

Seemingly a simple thing is very hard to do sometimes in Drupal. One thing is to change the order of node's links. For example, the main page lists node's teaser, where each node teaser is followed by links like "Nobu's blog", "Add new comments", and "Read More".

Amazon module of Drupal is very useful when showing items, but the current implementation is limited to one locale.

There is an API level patch here.
Allow dynamic amazon locale choice

I've modified the Amazon Filter module so that I can utilize the API patch. The modification allows amazon filter to have optional locale like

This will show the item from amazon.co.jp, instead of default local (usually U.S.)

<?php

Drupal requires to run a scheduled task periodically. It is implemented as a php file named cron.php. If you have access to crontab on your hosting server, you just need to add cron.php to it. But what if you don't? There are a couple of ways to run cron.php without using cron on the server.

There's a module to do that, called Poormanscron (what a nice naming!)
