It’s been a busy month so far and with Easter now upon us the year is showing no sign of deceleration.

I spent the last few weeks working hard to recover from my initial attempt at passing the Zend Certified Engineer exam. Having used PHP and other languages for several years I grabbed a copy of the Php|architect’s Zend PHP 5 Certification Study Guide, bought a few online practice tests from Zend and spent a few days scoring Excellent before heading down to the test centre confident I would be leaving with a Pass.
Forty five minutes into the exam I was racing through the questions thinking I had it in the bag only to be presented with a Fail upon clicking the End button…..Bummer

The score report gave no real indication of how close I came to passing, so wondering where I went wrong I scoured the net for any information that could help me prepare for my next attempt (which you get a 10% discount on if you ask Zend nicely). During my search I found the Zend Certification Forum, however it was broken and I had to ask for it to be fixed (which took a couple of days) before I could read others views on the exam. The Zend forum and site I have to say are not good adverts for PHP. The site often takes ages to load (is this down to PHP? people will think) and the forum feels pre web 2.0.

After a few hours of searching I finally found this PDF, the PHP 5 course material that outlines everything you need to focus on for the exam and provides enough examples to to get your head around the “gotchas” that are hidden in many of the questions. Second time round I passed, although many questions were similar to my first attempt and I answered them no different, I can only put my initial fail down to the PHP “gotchas” like:

What is the output of echo 09;

Post certification I had to ask for the Yellow Pages entry to be added (a common problem it seems), and after finally getting the page updated it seems to have reverted to its former state…..If only it was written in Java I keep thinking to myself.
Don’t get me wrong I am a big fan of PHP but feel its place is within the presentation layer (this site is written using PHP). When it comes down to middle tier processing I am yet to be convinced…

Speaking of Java, I decided that along with moving house this Easter (I need a server room ), I would open my mind to the world of software that is Oracle. The Oracle Database is hardly Open Source, however Oracle as a company do support the Open Source Community and to be honest I’m a knowledge junkie and need something fresh to feed my mind with (fear not MySQL).
Besides at the end of the day everything I learn from taking apart Oracle can be directly applied to the Open Source world, that is if it has not been applied already.

You may have noticed the Easter Bunny pic included with this post and if you are into Open Source you would have recognised him as Big Buck Bunny the star of the upcoming open movie Peach. That’s right there are only a few more weeks to the release of the movie and you can now take a look at the trailer before downloading your copy of Blender and having a go yourself - I can’t wait!

I’m sure by now you would have read the great news that is Sun Microsystems acquisition of MySQL!

Sun have been forging ahead in the Open Source world with OpenSolaris, an Operating System that scales to Enterprise proportions and is an ideal host for the number one Open Source Database Server that is MySQL.

Whether this will have any impact on the MySQL Linux / FreeBSD / Windows offerings is something I am sure the community will be watching closely, but in my experience Java runs much faster on Solaris as it can take advantage of the MultiThreading libraries that help Solaris set those performance records.
Don’t forget, it was not that long ago that combined with Sun hardware MySQL was able to set it’s own world records!.

With that in mind it should only be a matter of time before we will begin to see the fruits of Sun / MySQL’s labour and I don’t know about you but I can’t wait!.

How this move will affect the future of other database servers such as PostgreSQL and Oracle I cannot begin to imagine.
Personally I never understood how Oracle devoted so much attention to Linux when the Oracle server (and App servers) have such a dependency on Java (which as I say always works better running under Solaris )?
As for PostgreSQL, Sun have always endorsed PostgreSQL on Solaris, will we see this focus switch to MySQL in the near future?.

One thing is for certain, MySQL combined with Solaris makes for one world class package that is going to be hard to beat!!.

Whenever I decide to take a holiday I can usually guarantee that something cool will occur in the IT industry in my absence.

Now this holiday has been slightly different in many ways. I had to cancel my flight due to a sudden onset of Vertigo 1 day before I was supposed to fly. If like me you have never experienced Vertigo before, thank yourself lucky!. Having no sense of balance and intense room spin whenever you open your eyes is no fun at all, it took at least 2 days for me to stop being sick.

Having been able to actually use my laptop in the last couple of days I notice that the “cool thing” I usually miss on holiday turns out to be big trouble all over OpenSourceVille, the majority of which seems to revolve around licensing and intellectual property.

Who could miss the BSD vs GPL debate that I’m sure will rage for a long time after the ath5k driver had the BSD license removed in favour of the GPL. Stealing code was suddenly the headline for this action and the rift between the “Linux” developers and “BSD” developers increased once more.
Personally I feel the license should be as “Open” as possible and always apply the BSD license where I can. I want to be recognised as the author of any work I produce and protected against any misuse of such work (liability). With OpenSource development taking place in clear view nowadays, such visibility can only enforce your ideas and intellectual property. Why complicate things with over restrictive licenses…

While still on the topic of licensing it seems John Birrell is having to start all over again with a new port of DTrace on FreeBSD. The CDDL this time preventing kernel hooks from being added to the FreeBSD kernel. This seems such a shame as DTrace technology provides a massive benefit for software developers and will starting afresh really change the situation?, If not through licensing I am sure there must be patents on the intellectual property that Sun could enforce on any DTrace port? Just look at what is going on between NetApp and Sun at the moment.

So from licensing issues to patent infringement where it seems ZFS may not be as revolutionary as Sun claim and in fact NetApp actually came up with some of the functionality back in 1998. Dave’s Blog outlines all the details in what I can only describe as an excellent explanation as to how NetApp have had to file a lawsuit against Sun. Strangely enough I originally heard about this from the MySQL Planet! and not from any of the Solaris / OpenSolaris Planets each of which have around 45 Sun employee feeds?

We develop software to improve our way of life. Licensing and Patents although often necessary seem only to be hindering progress… Still it keeps us busy re-inventing the wheel.

On a good note, I was around to see the launch of the iPod Touch - if you can call that good…I might just wait until the drive space increases before I buy one, 16Gig seems tiny these days but then again the Touch would come in handy for on the go web browsing.
I also noticed Oracle 11g had been released (I obviously missed that one), although only for Linux at the moment?. I’m no Oracle expert but seeing as Oracle provide Java based development tools and my previous installs had a lot of Java involved surely Solaris would make a better fit?
