Dynamic cell references in spreadsheets with Google Docs

During my former internships in a consulting company I had to work A LOT with Microsoft Excel and often had to use dynamic cell references over multiple worksheets. Recently I started using the spreadsheets of Google Docs to track my bank account balance and to figure out where all my money goes. I decided to have one sheet for every month + one sheet of the month I want to analyze. But how do I dynamically change the reference to the sheet (the monthly sheet) I want to analyze without editing every single formula? Here is my solution:
  1. Create the target sheets and your overview sheet
    - I gave my sheets the names Month + Year (July 09)
  2. In the overview choose one cell that you want to contain the reference sheet and enter the sheet name
    - cell D24 in the example
    - Using the month names you might have to write 'July 09, otherwise Google will think it's a date.
  3. In the overview you can now dynamically reference to a detail sheet using the following formula:=INDIRECT("'"&&"'"&"!O2")
    - In my example =INDIRECT("'"&D24&"'"&"!O2")
    - For more details on the formula syntax read the
    Google Docs Help.
Try out my example. I wish the income would be real ;-)

Creating YTD transformation tables

The other day I had to setup a new data warehouse that will be used for reporting with MicroStrategy. Part of it was setting up the date dimension including the transformation tables. I had a quick look online and couldn't find any script doing the work for me so I created them myself (with the help of a colleague). All you need is an existing date dimension with date_id, year_id, quarter_id, month_id and week_id, you can find plenty of scripts for that online. YTD tableselect t1.day_id, t2.day_id
INTO YTD_DAY
from LU_DAY t1, LU_DAY t2
where t1.day_id >= t2.day_id
and t1.year_id = t2.year_id QTD table select t1.day_id, t2.day_id as qtd_day_id
INTO QTD_DAY
from LU_DAY t1, LU_DAY t2
where t1.day_id >= t2.day_id
and t1.QUARTER_id = t2.QUARTER_id  MTD tableselect t1.day_id, t2.day_id as mtd_day_id
INTO MTD_DAY
from LU_DAY t1, LU_DAY t2
where t1.day_id >= t2.day_id
and t1.month_id = t2.month_id  WTD tableselect t1.day_id, t2.day_id as wtd_day_id
INTO WTD_DAY
from LU_DAY t1, LU_DAY t2

Pentaho BI Server: Using action sequences as a web service with PHP

For my masterthesis I had to figure out, how to use the action sequences as webservice with PHP. According to the documentation you can receive soap messages but the action sequences don't offer a WSDL that would help you building your client. I also had problems with the http basic authentication, that Pentaho uses.
After a couple hours of research and try and error, I found a solution. I doubt thats the best way to go, but at least it works. All you need is the PEAR HTTP Request class.
Here is the code:

//PEAR Request
require_once 'Request.php';
$response = $req->sendRequest();

if (PEAR::isError($response)) {
echo $response->getMessage();
} else {
$req->clearPostData();
$req->setURL("localhost:8080/pentaho/ServiceAction");
$req->addQueryString("solution", "bi-developers");
$req->addQueryString("path", "reporting");
$req->addQueryString("action", "Testreport.xaction");
