Differences in the Interpreter
One gotcha is that the Prolog interpreter runs in a query mode, while code in file runs as assertions. Python, on the other hand, makes no such distinction. Code that you can compile in a file can equally be typed into the interpreter.
i.e. You have to write the rules in a text [...]

It’s so easy to get throwaway email addresses and throwaway domains combatting forum spam can be very difficult.
Here are some options:
1) use mod_access to ban open proxies
Similar to the approach used by denyhosts, this would blackhole proxies that are often used by bots.
2) publish ip addresses and signup dates to a central server

Leon Brambick has been grappling with the conundrum of navigational spaghetti (warning: gratuitious drawings of the Spaghetti Monster).
If we can’t implement URLs for easy bookmarking in desktop applications, what about having a site map for usabilities’ sake?

I’m testing out wordpress with sqlite, it seems to work pretty well so far.

Check out how a widget has spammed a blog
On this page about Factor Programming http://psalm35.blogspot.com/
It has a script in it’s footer:
<script src=http://www.oedemera.com/blogger_navbar/navbar_012.php>
When you visit the page with Javascript turned on, all the contents are replaced dynamically with ads.
This is beyond sick.

Note: The following doesn’t quite work as well.
From Price Change Blog (in Japanese):

function list_fields($table = ”)
{
// Is there a cached result?
if (isset($this->data_cache['field_names'][$table]))
{
return $this->data_cache['field_names'][$table];
}

if ($table == ”)
{
if ($this->db_debug)
{
return $this->display_error(’db_field_param_missing’);
}
return FALSE;
}
$sql = “SELECT * FROM “.$this->escape($table).” LIMIT 1″;
$query = $this->query($sql);

$retval = array();

if ($query->num_rows() > 0)

$row = $query->row_array();
