Local venture cap/tech blogger Paul Kedrosky recent posted that: Larry Ellison has allegedly cooked up a plan to do a wide-ranging roll-up of companies in the open-source space. Not just JBoss, but a host of others, from Spikesource to Zend, and more inbetween. About the only sizable o/s company left standing would be Red Hat.

This may be an effective short term strategy to preserve Oracle's revenue - if Oracle's customers are uncertain enough, they won't risk switching away from Oracle's products.

Consider Oracle's general strategy in this area in the last five years. When it comes to Free Software/Open Source products, it seems to me that they:

Mansour Safai, one of the great unsung heroes of the software development tools industry, passed away in the early morning of February 9th.  The picture above is Mansour with his son Nicolai. 

Although Mansour was a private person his impact in the industry was profound.  He created the most successful standalone debugger of the 1980s, Multiscope, the Symantec C++ family of development tools, Visual Cafe, the first Java IDE and finally, M7 a visual development environment …

I hated university and graduate school. I had a liberal arts education, so I was learning theory. Now, computer science theory is boring to someone who wants to make something useful. I understand why many folks dropped out of college to go work for the internet boom.

However, in the brief 5 years of work experience I’ve had since getting my Master’s, I’ve learned that a self-taught practicum only goes so far. Whether it’s system administration or database administration, the more basic levels of problem solving do not require much insight into how the system (OS or DB) works, the deeper problems do.

Some of that you can learn by doing, but most of the concepts aren’t learnable unless you’re digging into the source code.

That being said, I found a good web page today that goes through Entity-Relationship modeling. It’s very good, comprehensive.

There are more great news about MySQL 5.1.6.

MySQL 5.1.6 will introduce the new TRIGGER privilege. From then on, you won't have to grant SUPER privilege (which allows much more than creating and dropping triggers, so it might not be a good choice to grant the SUPER privilege to non-administrators) anymore for users who should be able to deal with triggers. The exact details are described in the Change log for MySQL 5.1.6.

At VLDB2005 in Trondheim, Norway I did a presentation that explained
the architecture of the implementation of disk data in MySQL Cluster.
It also explains the thinking process for the new node recovery
algorithm introduced as part of this work.

I just received an email notification stating that the "Logging into database table" feature as of my Feature Request 12304 has been pushed into MySQL 5.1.6.

If I got that right, there will be two new tables in the mysql schema - "slow_log" and "general_log". You will have the choice whether to store log information in the file system, like you were used to - or to store them inside these new tables.

Together with the new Event Scheduling Feature (which can perfectly play together with the new logging feature - as I already wrote about in an earlier article), MySQL 5.1.6 will provide very interesting new features - I'm very much looking forward to testing …

There are perfect places to look at - watch here:

MySQL 5.0 ( …

The partitioning development for 5.1 is close to its completion (apart from the
stabilisation phase). An important part of this development is the ability to
prune away partitions not used in the query. Here follows some guidelines how
the optimiser handles this at the moment.

For most functions the optimizer can only handle equality conditions thus:
where partition_field = 2
or
where partiiton_field IN (2,3,4)

In this case the optimiser can use this independent of what the partition
function is. It will do so by actually applying the partition function on the
equal value thus:
partition_function(2) = partition 3
partition_function(3) = partition 5
partition_function(4) = partition 3

It will set a bit in partition_used bitmap to indicate which partitions are used
to indicate to the executer which partitions to scan. …
