CSS Drop Shadows
This handy technique allows us to build flexible CSS drop shadows that we can apply to any arbitraryblock elements. The beauty of this method is that most exisitng techniques use images to create the shadow effect. This script is lightweight and uses pure CSS! ENJOY!

Making SQLITE/SQLITE3 executable scripts.
Use "here document" statements to build complex script files with embedded SQL statements via the sqlite/sqlite3 utility.
Note that being in a bash script means that you can expand $-variables inside the SQL code directly. This is, however, not advised unless you can be sure that only trusted, competent people will run your code. Otherwise you'll be facing SQL injection attacks.

Get HTML/XML output of your MySQL queries.
The mysql command line utility can be used to build databases, manipulate them, etc. It can also be used as an ad-hoc query tool with HTML-snippet output. Consider this code:
The resulting output will be a mess of +, - and | characters used to frame boxes around the values. Now consider instead:
The output of this is <TABLE/><TR/><TD/> code that can be cut-and-pasted into your HTML editor of choice. Complex queries not easily put into a single -e string can be done thus:
Note that no HTML is generated for any query that does not have a result set (like INSERT or UPDATE).
Change the -H to a -X to get XML output (without a DTD/XSL description, unfortunately).
1 2 mysql -e "SELECT * FROM mytable WHERE somecondition='somevalue'"
The resulting output will be a mess of +, - and | characters used to frame boxes around the values. Now consider instead:
1 2 mysql -H -e "SELECT * FROM mytable WHERE somecondition='somevalue'"
The output of this is <TABLE/><TR/><TD/> code that can be cut-and-pasted into your HTML editor of choice. Complex queries not easily put into a single -e string can be done thus:
1 2 mysql -H < myqueries.sql
Note that no HTML is generated for any query that does not have a result set (like INSERT or UPDATE).
Change the -H to a -X to get XML output (without a DTD/XSL description, unfortunately).
