Besides Postgres, NeverBlock now also supports MySQL through the new MySQLPlus adapter. InfoQ talked to two of the developers of MySQLPlus and discussed NeverBlock and non-blocking database adapters with developers of Ruby's Oracle and SQLite interfaces.

Over a year ago I wrote about pretty nasty Innodb Recovery Bug. I ran in the same situation again (different system, different customer) and went to see the status of the bug… and it is still open.

Well now that SQL Server 2008 has shipped, Zach and I are starting to put the finishing touches on all of our SQL Server 2008 early adopter initiatives and move on to planning for future releases. Before we do that I have some unfinished business to take care of.

I've made a couple of changes to my defragment indexes stored procedure, isp_ALTER_INDEX, based upon feedback I've received from my blog readers. For those unfamiliar with this object, it defragments indexes in SQL Server 2005 using the ALTER INDEX command. Check the comment header block for its documentation.

Have been using Filemaker for over 4 years now and only just have I found the need for a chart. My needs were simple I didn’t need anything flashy and it needed to be something quick to implement but with enough options to not leave me wanting. Here is a list of the ready-made solutions I found and finishing with what I ended up using:

Microsoft has announced two SQL Server Exams that will retire on March 31,2009. Those are 70-228 and 70-229. Microsoft has announced that 10 more exams will be discontinued.

ODBMS.ORG, a vendor-independent non-profit group of high-profile software experts lead by Prof. Roberto Zicari, today announced the exclusive publication of a second series of new user reports on using technologies for storing and handling persistent objects. Today, 6 additional user reports (12-17/08) have been published, from the following users: Ajay Deshpande, Persistent Horst Braeuner, City of Schwaebisch Hall Tore Risch, Uppsala University Michael Blaha, OMT Associates Stefan Keller, HSR Rapperswil Mohammed Zaki, Rensselaer

Although the temperatures are still warm, it's Christmas Day here at the Baker's Dozen, and we're about to unwrap thirteen major SQL Server/SSRS 2008 gifts from Microsoft. A major software release either contains a substantial number of enhancements, or a small number of substantial enhancements. The last two releases of SQL Server remind me of the two types of Christmases: SQL 2005 was like receiving a large number of presents, and SQL Server 2008 is like receiving a smaller number of big gifts. Those of you who asked Santa for the ability to INSERT/UPDATE/DELETE in one SQL statement, or to specify multiple GROUP BY statements in a single SQL query

SQL Server has been long accused of not having a complete representation of Date and Time variables. However, SQL Server 2008 brings new date and time variables to allow for more precise control over these variables types, which Nidal examines in this article. He demonstrates the concept with the help of relevant SQL statements and screenshots of the generated output.

In this article, Nidal talks about the available enhancements in the group by clause of SQL Server 2008. The grouping sets feature allows the developer to group data selected in the same select statement into different groups. He examines the techniques involved with the help of relevant SQL statements followed by analysis and a screen shot.

One of the nice things about LINQ to SQL is the ability to extend the types of the generated entities. Another nice thing is being able to get typed results from stored procedures. Let's try and combine the two together.

I was planning to put a quick spike together on putting single sign-on, using CardSpace, OpenID and Windows Live, into an application to test it out for a project at work. Maybe it was because of the weekend, but I was quite enthusiastic and added several technologies to the sample which I had never used before.

Following up on my Previous Post I decided to do little test to see how accurate stats we can get for for Index Stats created by ANALYZE TABLE for MyISAM and Innodb.

The new (GA 1.1) version of the JBoss Cache Demo is out. The JBoss Cache Demo was created to help visualize the capabilities of what is otherwise not a very visual project. It ships with JBoss Cache 2.2.0.GA and all jar dependencies, and requires JDK 1.5 or above.

When you’re starting out with NHibernate, it’s sometimes hard to find good examples. Most examples online are too simple, or are incomplete (just the mappings, but no code for instance). It’s always easier if you have some examples that are large enough, but still small enough to be easy to grasp. So i created mappings and classes for the Northwind tables. I figured this could be useful reference material for anyone new to NHibernate so i’m making the whole thing available for everyone. You’ll find examples of one-to-many, many-to-one and many-to-many associations in there

The Carbon Five Database Migration framework and maven plugin provides a simple solution to problem of managing discrete, incremental changes to databases over time across multiple environments. Each migration is versioned and tracked when applied to the database. Sensible defaults reduce the amount of necessary configuration, though the framework can be configured and extended. The recent 0.9.1 release includes some core framework improvements and additional maven plugin functionality.

What if you suddenly had the ability to serve mutliple concurrent requests in a single Rails instance? What if you had the ability to multiplex IO operations from a single Rails instance? here are test results from using NeverBlock with ActiveRecord.

The JRuby project is making Ruby faster and more scalable than ever. One advantage to running Rails on the Java Virtual Machine is that you can leverage other Java libraries, like the Apache Derby database. The blend of Derby, JRuby, and Rails allows for rapid prototyping of dynamic Web applications. Learn how to use these technologies together to prototype your next great idea.

Easy way to access MySQL Database from the remote location

Despite the intimidating material, there are real architectural and design issues that these discussions present that should be in the mind of anyone dealing with large datacenters that scale globally or even nationally. The approach of GIGA+ file storage, maidsafe’s new computer architecture, and NetWorkSpaces for the R language was uniform: off-loading responsibility for management of data (meta or otherwise) to all vertices in the deployment graph instead of a central repository.
