Found great article about Drupal 6.x performance

must read & keep

If you need to theme the node.tpl.php for a specific node, create node-[nid].tpl.php file from node.tpl.php

add to your template.php file

function THEMENAME_preprocess_node(&$variables) {
  
  $node  = $variables['node'];
  if (!empty($node)) {
    $variables['template_files'][] = "node-" . $node->nid;
  }
  
}

one of our hosted sites, has start making problems an refused to load the homepage, giving a "not found" error to the browser
looking in the logs, we found this line:

PHP Fatal error: Cannot redeclare product_has_images() ...

after we looked into it, and tried all sort of hooks to catch the cause
of the error, we got a prime-suspect:
the PHP Cache APC

so we restarted apache... and it fixed everything

 A young drupalist, that has recently learned Drupal, asked me what do I recommend for him as the next course he'll take:

PHP, Databases, or CSS ?

So I went and asked my friends and drupal colegues on LinkedIn, here is a link to the question What is the best next-step course for a beginner-drupalist: PHP, Databases, or CSS ?

here are the answers by the drupal experts:

Recently i got this error in my log
Cron run exceeded the time limit and was aborted.

so why does cron, shouted this ?

I have found nice snipet to track the source of the error

<?php
// redirect only if this is not cron script  
if ($_SERVER['SCRIPT_NAME'] != '/cron.php') {
  drupal_goto('<front>');
}
?>

apparently it was because i have added a redirect page to keep an old path and avoid 404 error
so i have added a page with php code with a simple drupal_goto()

having this problem ?

Having a live drupal website, that needs to be upgraded, or just a simple task such as adding Languages or changing a Themes, we would like to hold all content changes, till the work is done.

We found a nice module to set the site for Read-Only mode

http://drupal.org/project/readonlymode

Using the module is simple, just need to check the box, and the site moves to a Read-Only mode

The only thing missing in that module was that it still allows to add comments.

New module

Dark Shaddows on Internet Explorer :-)

We built a drupal site with google maps, and it worked fine on our browsers. However, our customer pointed for us on a big & scarry shaddow where the markers should have seen

Aperently he was using ie7, and we found a javascript error in the markers. Doing some research and changes, we returned to the default settings, and suddenly it worked fine.

If you wonder "How to separate user generated content from editorial content", and

build your wiki-style discussion page,

we found a Drupal module - Talk that you can use for building a discussion page from the users' comments

Here is the link to module Talk

We had to use the filepath instead of fid more then once,

Here is a small function we wrote, returning the filepath from the fid

/**  * Get filepath by fid  */ 
function filepath($fid) {   
if (is_numeric($fid)) {     
  $filepath = db_fetch_object(db_query("SELECT filepath FROM files WHERE fid = '%s'", $fid));     
if (is_string($filepath->filepath))       
    return $filepath->filepath;     
  else return FALSE;   
} else return FALSE; 
}
