When enabling Drupal modules a 500 Internal Server Error can often appear with the default installation. Too identify the cause of the problem look in the error_log file for your web server.
Each time I have encountered this problem the cause has been due to the PHP memory limit being exceeded. The typical error message if you have allocated 16MB is:
PHP Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 77824 bytes) in /xxx/yyy/zzz/xxx/drupal/modules/node/node.pages.inc on line 221
There are several very easy ways to fix this by increasing PHPs memory limit:
memory_limit = 16M to your php.ini file (recommended, if you have access)ini_set('memory_limit', '16M'); in your sites/default/settings.php filephp_value memory_limit 16M in your .htaccess file in the Drupal root
See: http://drupal.org/node/76156 for more details.

If you want to do a recursive chmod on a set of files below a given directory or folder using the bash shell you can do the following:
find . -type f -name ‘*.php’ -exec chmod 644 {} \;
This command can be easily adapted to work for other file types or modes. The ‘.’ following ‘find’ specifies the root directory for the operation.
How to chmod all folder/directories below the current directory…
find . -type d -exec chmod 755 {} \;
Alternatively, chmod on all directories below a given directory (./somedir)
find ./somedir -type d -exec chmod 755 {} \;

A quick example of how to get the name of the localhost using the Java InetAddress class.
String hostname = null;
try {
InetAddress localhost = Address.getLocalHost();
if (localhost != null) {
hostname = localhost.getHostName();
}
} catch (UnknownHostException e) {
e.printStackTrace();
}
System.out.println(”Hostname is ” + (hostname != null ? hostname : “Unknown”) );

Configuring the Eclipse IDE to use a local CVS (CVSNT) repository on windows isn’t an entirely obvious procedure since CVS and Eclipse are geared to working on Linux/Unix. It is actually quite simple to do but if you miss a couple of points you could spend hours fiddling with it without any luck.
The following article by Seth Thompson walks you through the process:
