PHP Object Cloning

In our advanced PHP training course we cover object orientation and how it is implemented in PHP.

Oracle Java Developer Day - Johannesburg, South Africa

The 21st May 2010 was Oracle Java Developer Day, here in South Africa. The event was a great success and it was great to meet Arun Gupta and chat to him about GlassFish and JEE 7. I presented two sessions at the event and have attached the slides below.

The first session was on GlassFish and the 2nd was on Java Logging Frameworks. If you are looking for GlassFish training see our offered GlassFish training courses!

SELinux - An Introduction Presentation

"SELinux - An introduction" was the title of the presentation I gave this evening, 26 March 2012, at the Jozi LUG. SELinux is one of those Linux features that many administrators quietly turn off so as to get on with the business of managing their servers; but of course its not considered polite to say this in public.

With the targeted policy there really is no reason why SELinux cannot be used by default in most installations with the strict policy only being used if it is really required. Of course there is also apparmor that can be used.
