These are not the reason why people trust in open source applications.
Now why am I ranting like this?
Zend has officially proposed a PHP IDE for eclipse (PHPEclipse is
not an official Eclipse project) and they are certainly poring in
development resources which cost them …
Being a CVS Version Control Person, I’ve had to learn Subversion as part of Open Source Contribution. Both MySQL and JMeter use SVN.
Steps for integration of SVN into Eclipse IDE. Refer to Subclipse for more information.
Installation of JMeter via SVN
I don’t think I’ve ever installed MySQL via .rpm I have always installed via .tar.gz primarilarly because I’m an /opt system administrator from my old UNIX days. so my first experience installing on my CentOS 4.2 (aka RHEL 4).

As mentioned in my earlier post Emulating Oracle Output Functionality, I’ll be speaking at the MySQL Users Conference on the topic of MySQL for Oracle Developers. Here is the second in a series of points regarding current MySQL Stored Procedures and Functions functionality.
3. Named Parameters
Parameters passed to Procedures under normal operations can be considered positional parameters. For each parameter, a calling statement is required to pass the same number of parameters and in the same order. Named parameters allows the user to pass parmeters in the order of their choosing, and also not pass all parameters. …
[Read more]I stand corrected on my earlier post Emulating Oracle Output Functionality (which I’ve updated) when I made a reference to MySQL catching up. That was not what I was implying, that MySQL had to catchup to Oracle. I was indeed making reference that MySQL is a 10 year old product, Oracle almost 30, and with a far greater historical R&D budget, MySQL as an organisation has for lack of a better term, entered the race at a later time. One could also argue it’s not a race, I’m just using this analogy.
For those that might have thought this in reading my earlier article, I’d encourage you to re-read my updated introduction for my clarification and correction.
The comment was made to me, “Oracle is very good at being Oracle” which is totally correct, and the “MySQL’s market now overlaps that of Oracle, and so there is competition.” Indeed Oracle, as a …
[Read more]Given a new Linux Installation, the following is my recommendation for installation of MySQL for a experienced software developer giving flexibility in a development environment.
1. Under normal circumstances, most distros include MySQL either in a default server installation or on the distribution CD’s. You should first ensure MySQL is not installed.
2. All products can be downloaded from the MySQL Downloads page.
3. Download MySQL 5.1 Beta - Linux (non RPM, Intel C/C++ compiled, glibc-2.3), this product is close to production release and stable. This also includes both Server and Client as well as provides flexibility in installation location and …
[Read more]I was asked a simple question today by a collegue who is an experiened Java Developer and Oracle user and had just installed SUSE on his personal laptop, to align closer with his work environment. What MySQL should I install, the MySQL web site has this and this and this?
Simple question, but the answer isn’t as simple, especially when MySQL now has a number of different products encompassing client functionality in addition to the MySQL server.
Oracle got it right with the latest edition Oracle 10g Express Edition (XE). A simple one rpm install that includes the Oracle Server, Oracle client, a Web Based Administrator, Query Tool and Application Development tool. I guess as we are all experienced, the simple question isn’t something we have a some notes on handy, hence the purpose of my entry …
[Read more]I’m a data modeller. I specialise in this, and for a number of years on large projects I’ve been able to focus on this single task within the System Development Life Cycle of software development for several months at a time. Unfortunately what depresses me the most, is I can’t get a full time position in what I’m an expert in. It’s not a specialised skill that an organisation can use on a full-time basis, unless it’s a large organisation, and quite frankly, Brisbane isn’t a market that can support the diversity of large organisations. (caveat, large organisations that are proactive in software development, not just large organisations that have significant IT requirements, but do not work proactively). This is why I can also do Software Development, Database Administration, and even System Administration. Again, I’m not good enough to fill one of these positions in a larger organisation as an expert, but I can generally hold …
