Netbeans 6.1 was released recently which includes PostgreSQL JDBC driver. It had been a while since I had done programming as a developer, so I decided to take it for a test drive to refresh my programming skills with it. Well here is the resulting demo application:

Remember it is just a demonstration application. It requires your client (laptop or desktop ip address) to be trusted in  pg_hba.conf  ip adddress in order to work with your database.

Update on Sept 30,2008: Added a new dialog box which includes option for password and also the new L&F called nimbus (JRE6u10 recommended). Here is a quick screenshot:

MemProxy 0.1 is out!  It has taken me a while, but I have finally gotten around to releasing the code that I credited with saving us during a Yahoo! mention.  It is a caching proxy "server" that uses memcached for storing the cache.  I put server in quotes because it is really just a PHP script that handles the caching and talking to the application servers.  Apache and other HTTP servers already do a good job talking HTTP to a vast myriad of clients.  I did not see any reason to reinvent the wheel.  Here are some of the features that make it different from anything I could find:

• 
  
• Uses memcached for storage
  
• Serves cache headers to clients based on TTL of cached data

There are only two kinds of storage devices - those that have failed, and those that are about to fail. That's the view most datacenters have about the traditionally mechanical devices pejoratively referred to as "spinning rust." All disk drives fail, cheap drives fail faster.

If the average time to fail is five years, you and your laptop can make do with the occasional backup. But when an average enterprise has 100, or 1,000, or increasingly 10,000 or 100,000 individual disk drives, failure is a daily, if not hourly occurrence. Mechanical devices fail.

And with failure comes the potential for losing data - using commodity disks to save your boss $500,000 does her no good if she's fined $50,000,000 for violating data retention regulations. Stock transactions, medical images or feature length movies - take your pick, some data has to be perfect. Not a decimal point or pixel out of place.

That's exactly why, years …

Sun's Businessweek advertisement for MySQL

I'm sure there are many benefits for MySQL being a part of a large IT vendor like Sun Microsystems, but the advertising budget probably doesn't hurt. Reading Businessweek today at lunch, I bumped into this MySQL advertisement in ...

Here's my presentation I gave June 9, 2008, at the Twin Cities MySQL and PHP User Group about my highly available cluster using DRBD and Heartbeat.

I added a few slides and cleaned things up a bit. The presentation went well and we had a lot of good questions.

The MySQL and PHP User Group will be taking some time off over the summer. There will be another meetup mid-summer to come up with some ideas for future meetings.

Last week, I uploaded the first screenshots for opentaps analytics to the opentaps documentation wiki. While this application is still in its early stages, I thought he screenshots should help you see what we've been working on.

What you're looking at is an application that takes operational data from the opentaps Open Source ERP + CRM system and transforms them into an analytical data warehouse using the Kettle ETL tool. Then, from this data warehouse, we have built dashboards, maps, drill downs, and reports.

The goal of opentaps analytics is to help you make better business decisions with your data by providing you with …

When a Forrester Research representative emailed with the following survey highlights, I was more than a little surprised: "Forrester released data today analyzing trend lines in enterprise open source usage in 2007. Among the key findings: Seventy percent of decision-makers responded that they don't have interest or have no plans to adopt open source software; Only 23 percent of respondents said expanding their use of open source software was a priority; Security is the main concern around adopting open source software. Eighty-eight percent of respondents said it was an important or very important concern." The data is from 1,017 decision... READ MORE

We recently moved some databases to different servers, and I altered our mySQL slave configuration files to take into account some of the databases we wanted to replicate (Replicate-do-db) and others that we wanted to ignore (Replicate-ignore-db) -- each of these server cases were mutually exclusive.All went well, until I found a peculiar error:Error 'Table 'db101.table101' doesn't exist' on
