Dynamic Drive DHTML Scripts- Google Map Selector
This jQuery script lets you easily embed a Google Map on your page that supports switching between multiple addresses. A two column layout is presented by default, with the list of desired addresses on the left column and a Google Map on the right. The script automatically adds a CSS class of "selected" to the selected address’s LI container to highlight the current address while updating the "View Larger Map" link below the Google map to the appropriate link as well.
Exclude Posts and Pages in WordPress Search
Sometimes you don’t like to display every post and page on search results. Today I like to show you how to filter the search in your frontend. Therefore I add a filter to the query of WordPress and exclude the according posts or pages of the search.
Fast 404 | drupal.org
Drupal has expensive 404 errors. On an ‘average’ site with an ‘average’ module load, you can be looking at 60-100MB of memory being consumed on your server to deliver a 404. Consider a page with a bad .gif link and a missing .css file. That page will generate 2 404s along with the actual load of the page. You are most likely looking at 180MB of memory to server that page rather than the 60MB it should take.
That’s where Fast 404 comes in. This module combines a very common method of handling missing image/file 404 errors (discussed here and planned for Drupal with a method created by dpardo (a co-maintainer of this project) to deliver super fast 404 error pages for both missing images and bad paths. Depending on which method of implementation you choose (aggressive or super aggressive) you can deliver 404 errors using less than 1MB of memory on your server.

E-Mail 404/403

Eine E-Mail zu versenden sobald ein 403/404 Fehler auftritt finde ich nach wie vor eine gute Idee.

Auf NetTuts gibt es ein Tutorial zu dem Thema.

Website error pages are perhaps one of the most overlooked pieces of a fully rounded website. Not only are they important but they give you the opportunity to have a little fun. Although many web developers rely on server logs to keep an eye out for hits on error pages, I’m going to take a different approach by using a PHP generated email. In addition, we will spice up the design a bit, add basic navigation and link to the website sitemap.

Server Load bei WordPress 404

Alex King über den Zusammenhang von 404s bei WordPress.

It’s a really elegant system and works very well. However, it also means that 404 requests - http requests that result in a “file not found” message - have a much higher impact on the server than a traditional 404 request does. For every 404, the server instantiates WordPress, does some database work to try to see if it can figure out what to serve, etc.

Der Artikel Creating custom error pages in Drupal beschreibt die Vor- und Nachteile von 3 Möglichkeiten Fehlerseiten in drupal anzuzeigen:

Drupal’s built-in support for error pages (@ /admin/settings/error-reporting)

Search404.module (404’s only, of course)

Customerror.module (404 & 403)

Der Author spricht sich klar für das Customerror.module aus und liefert Code für sinnvolle Fehlerseiten mit.
