OpenStreetMap is a very good crowdsourcing map application. It has a cool feature which tag the road in the map by its type. That feature enable us to identify the type of road such as main road, pedestrian road, living street, etc. Besides that, we can also use that feature to extract only the road part from the map. This can be useful when we want to build a routing system which need the road part only.

For example, when editing a node, in content authoring section, there is an autocomplete textfield for entering the author for the content. By default, all users will be available in the autocomplete list, but there might be a case when we need to exclude the blocked user from the list. Fortunately, we are able to do that by using one hook function called hook_query_alter.

Salix is a Linux distribution derived from Slackware.

When we want to add newsletter feature to our Drupal website, we might end up finding the simplenews module as the solution. But, there is one problem that so many people asked about in the internet. By default, simplenews will send the whole node content in the body of the newsletter e-mail, not the teaser. Ideally, the newsletter e-mail will contain the teaser or trimmed version of the full content with the link to read it online to our website.
