Yesterday, I got myself a Mac Book with 2GB of RAM and I am very excited about it. Earlier I created a Microsoft Windows XP virtual machine using Parallels. The whole process was a breeze. While going through Parallels documentation that it partially supports Solaris 10 as well. I had a DVD with Solaris 10 6/06 handy (which folks at Sun gave me when I visited them around two months ago in New York) so I thought why not try it out as if it works, I would have my dream machine ready. My work is 100% Solaris 10 shop as far as my professional duties are concerned. However, I didn't want to buy a Solaris 10 laptop due to lack of support available.

One cool thing about Parallels is that it lets you choose between "Shared Networking" and "Bridged Networking". Shared Networking is ideal if you don't want your virtual machine to have its own IP. This way your virtual machine will not be visible on the network.

Overall, creating …

The ETL load time can be reduced, for large data volumes by running several tasks in parallel rather than serial.

In addition to the data that we receive from the Sierra stores, in the given example, let us assume we receive sales transaction data from the Tundra line of stores as well. If the data file from the Tundra store arrives in the normalized structure, we might want to join the files together for data profiling. We can do this by loading the 3 files into 3 separate tables and join the 3 tables together in the data profiling SQL query. If this join needs to happen …

This release of the innotop MySQL and InnoDB monitor is a major upgrade in terms of functionality, code quality, and interface consistency. It is the result of me working for over a month to get innotop into shape for the recent MySQL Conference and Expo. This article is a summary of the changes and a look at what's coming next.

How do you like your SQL served? Personally I like this type:

SELECT   dc.state
       , dd.year
       , dd.month
       , sum(fs.sales) as total_sales
FROM     fact_sales     fs,
         dim_date       dd,
         dim_customer   dc
WHERE    fs.customer_tk = dc.customer_tk
AND      fs.date_tk     = dd.date_tk
AND      dd.year IN ( 2006, 2007 )
GROUP BY dc.state
       , dd.year
       , dd.month

Obviously, it’s inspired by simple star schema querying. Anything goes for me, but I kinda like a little bit of “structure” in my SQL (no pun intended), just a little bit of overview.

What’s your favorite SQL format?

P.S. We will soon be launching PDI version 2.5.0, stay tuned!

This is the second part of the "Howto write a FindBugs Bug Detector" (see the first part here). To understand why one would write the kind of detector mentioned here, you should read the first part if you do not already know it.

Last time I presented a detector that is able to detect static fields of the types java.util.Calendar and java.text.DateFormat. While declaring fields like this may be suspicious, there is not necessarily something wrong with the code. The real danger comes from calling methods on suchlike fields, especially if they are not synchronized to protect them against concurrent access. So in this article we will extend and improve the existing detector to cope with this problem.

Something to chew on

This a simple class that uses a static Calendar instance. It does not …
