Getting Started with Qtopia

From the horse's mouth (Trolltech) come instructions on how to get started writing applications for Qtopia.
Cross-Compiling

So, now that we have a reasonably working program, we need to cross-compile this for the Archos device. We have to change the project settings to find the proper libraries.

We are now ready to cross-compile, so clean the project by selecting Build→Clean Project from the menu.

You need to change the Make Options, using the Project Options→Make Options dialog: 

Name: QTDIR Value: /opt/Qtopia/arm
Name: QPEDIR Value: /opt/Qtopia/arm
Name PATH Value: /usr/local/arm/bin:/opt/Qtopia/tmake/bin:$PATH
Name TMAKEPATH Value:/opt/Qtopia/tmake/lib/qws/linux-arm-g++

Delete the Makefile, and run the following command from the command line to create the Makefile for compiling using the arm-linux compiler: 

# export TMAKEPATH=/opt/Qtopia/tmake/lib/qws/linux-arm-g++
# tmake -o Makefile skizzy.pro

Press F8 to build the project. You can now take the resulting binary, transfer it to the Archos device using USB, and run it from there!

If you want to create an installable package, Qtopia uses the Itsy Package Management (ipkg) available from handhelds.org, to install things using the Software Packages application. More information about ipkg and Qtopia development are available from Trolltech's Qtopia.net Web site.

How to install Qtopia core for arm?

I'd be grateful if you could tell me step by step how to install Qtopia for arm. Whether there are any compatible (more importantly incompatible) toolchains for Qtopia core to work. I tried to compile Qtopia core 4.2.2 for arm by giving ./configure -embedded arm, and the make failed. I am using the toolchain with binutils 2.17 and gcc 4.1.1. My native gcc has version 4.0.0
Qtopia core has compiled successfully for my i.386 machine.

Qtopia application deployment

The article is wonderful and it covers the things for beginners...

But we need some more guidelines on 'Deployment of advanced
Qtopia application on target board' because any small application
could be deployed to the target board without any problem..

So we need some more guidelines about the deployment of application
that uses pim library ...developed using Qtopia 1.7 sdk but the
target has qtopia 1.5 ( does not have any pim libraries )

Thanks

Fabric-Based Computing Enables Optimized Hyperscale Data Centers

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
