| Windows to UNIX porting, Part 1: Porting C/C++ sources
Software programs are often made to run on systems that are completely
different from the system in which the program is coded or developed. This process
of adapting software across systems is known as porting. You might need to port
software for any one of several reasons. Perhaps your end users want to use the
software in a new environment, such as a different version of UNIX(R), or perhaps
your developers are integrating their own code into the software to optimize it for
your organization's platform.

| Windows to UNIX porting, Part 2: Internals of porting C/C++ sources
Part 1 of this series covered the typical C/C++ project types you work with
in a Microsoft(R) Visual Studio(R) environment and introduced the processes of porting
dynamic and static library project variants to a UNIX(R) platform. Part 2 delves
into some of the compiler options used to build Visual C++ projects and the UNIX and
g++ equivalents, takes a closer look at the g++ attribute mechanism as it relates to
porting, and examines some common problems you might encounter while porting from a
32-bit Windows(R) environment to a 64-bit UNIX environment. It concludes with an
overview of concepts for porting multithreaded applications and an example project
that shows you how to pull all these pieces together.

| Guide to porting from Solaris to Linux on x86
Solaris is considered one of the closest flavors of UNIX to Linux, but for migration purposes, there can be differences between the two in the areas of memory mapping, threading, or natural language support (to name just a few). This porting guide gives you advice on planning for the port to Linux/x86, and helps you understand the differences in the development environment and architecture.

| AIX security reporting
Generating IBM AIX security reports should reflect the current security model overview of your system, and these reports can then be presented to managers or audit to show how your AIX system is managed with regards to security. In this article, I will demonstrate what type of attributes could be collected and why.

| Avoid traps when porting Java Web applications from Windows to AIX
Examine three traps you could fall in when porting Java(TM) Web applications from Windows(R) to AIX(R), and learn how to maneuver around them. When developing applications, you normally do so in a development environment and then deploy to a production environment. If you develop on Windows and deploy to a UNIX(R)-like platform, you might encounter subtle pitfalls. The first trap sets up different line separators in Windows and AIX, the second shows the best approach to locate a file in different development environments and operating systems, and the third is a common exception in socket communication.

| AIX 5.2 performance tools update, Part 3
This is the third in our series on AIX 5.2 performance tools updates. This article discusses the new AIX 5.2 tprof command and the Cpu Utilization Reporting Tool (CURT). tprof samples CPU utilization and accounts for time in threads and program modules using the system clock interrupts, which occur at every 100th of a second. CURT reads an AIX trace sequentially and processs the trace hooks, doing bookkeeping along the way to produce a CPU utilization report.

| Move data quickly between AIX LPARs using Logical Volume Manager
Migrating data from one LPAR to another can be challenging. You need to set
aside some disk space
on the new LPAR and create file systems. And whether you choose to copy the data across the network
or do a backup and restore, a large amount of data can take many hours to move. Wouldn't it be good if you could gift wrap your data, send it to a new LPAR, and then unwrap it ready to use? The IBM AIX operating system Logical
Volume Manager (LVM) lets you do just that by exporting a volume group from one LPAR and importing it to another one.

| LDAP and the iPhone
A multitude of libraries have been written for UNIX systems. Many of those libraries have been released using open source licenses that allow a library's source code to be reused in new projects. By porting an existing library to a new platform, a developer may be able to save the time it would take to duplicate the development work to achieve the same functionality on the new platform. This is the first of a two-part article series on porting the OpenLDAP client libraries to the iOS. Part 1 walks the reader through the steps of importing the OpenLDAP source code into Xcode and building two static libraries for the iOS. Using the Xcode project created in Part 1, Part 2 will guide the reader through the creation a simple iOS application that executes basic queries to an LDAP server using the OpenLDAP libraries.

| Python testing frameworks: Selecting and running tests
The recent emergence of industrial-strength Python testing frameworks
means that Python tests are being written more succinctly,
more uniformly, and with better reporting of results than ever before.
This article examines how the three most popular testing frameworks
identify and gather tests,
and what support they provide for writing entire layers of tests
that share common setup and teardown code.
