A Generic Searchable Range Collection (.NET)
A common programming task is to match a value to a group of ranges in order to find a value associated with that range. The .NET framework does not provide a collection class to support this functionality so a new generic collection must be created.

The essence of the code analysis library VivaCore.
The article tells developers about VivaCore library, preconditions of its creation, its possibilities, structure and scope of use. This article was written simultaneously with the development of VivaCore library and that's why some of the details of the final realization may differ from the features described here. But this won't prevent the developers from getting acquainted with the general work principles of the library, mechanisms of analysis and processing of C and C++ source code.

C++ header dependency tricks
Keeping header file dependencies to a minimum in C++ is always a good idea. There’s a great book on the subject. John Lakos’s Large Scale C++ Design , but there’s plenty of little tricks that aren’t mentioned. In this article I discuss a cool trick I’ve discovered in reducing dependencies, particularly useful for STL headers.

Anatomy of Linux Synchronization Methods
In your Linux education, you may have learned about concurrency, critical sections, and locking, but how do you use these concepts within the kernel? This article reviews the locking mechanisms available within the Linux Kernel 2.6, including atomic operators, spinlocks, reader/writer locks, and kernel semaphores. Also try the Linux Kernal tutorial to learn how to compile, and customize a Linux kernelto suit your needs.

Static code analysis for verification of the 64-bit applications
The coming of 64-bit processors to the PC market causes a problem which the developers have to solve: the old 32-bit applications should be ported to the new platform. After such code migration an application may behave incorrectly. The article is elucidating question of development and appliance of static code analyzer for checking out of the correctness of such application. Some problems emerging in applications after recompiling in 64-bit systems are considered in this article as well as the rules according to which the code check up is performed.

Some examples of the 64-bit code errors
While porting 32-bit software to 64-bit systems there may appear some errors in the code of applications which were written in C++ language. The cause for these hides in the alteration of the base data types (to be more exact, in the relations between them) with the new hardware platform.

64-bits for C++ Developers: from /Wp64 to Viva64
The development of the 64-bit solutions market has given some new tasks in the field of their verification and testing. The article describes one of such tools - Viva64. It's a lint-like static code analyzer assigned for exposure of errors related with the peculiarities of the 64-bit platforms. The prerequisites for the creation of such an analyzer and its connection with the "Detect 64-Bit Portability Issues" regime in C++ compiler Visual Studio 2005 are covered in the article.

The forgotten problems of 64-bit programs development.
Though the history of 64-bit systems development makes more than a decade, the appearance of 64-bit version of OS Windows raised new problems in the sphere of development and testing applications. In the article there are considered some mistakes connected with 64-bit C/C++ code development to Windows. The reasons are explained according to which these mistakes didn't find their reflection in the articles devoted to the migration tasks and are unsatisfactorily detected by the majority of static analyzers.

Command Line Efficiency with GNU Perfect
Learn how to use gperf for effective command-line processing in your C/C++ code. The GNU tool gperf is a "perfect" hash function that, for a given set of user-provided strings, generates C/C++ code for a hash table, a hash function, and a lookup function.

Playing the Lottery with Eclipse CDT
Aside from Java IDE, Eclipse can also work with PHP, Ruby, and Groovy, C, and C++. In this article, you will learn how to build and develop applications in C++ using the Eclipse C/C++ Development Toolkit (CDT), and Standard Template Library (STL). This allows you to streamline the process and take advantage of powerful features C++ offers.

Using vector instead of arrays to prevent most of
Most of beginners define arrays of limited size such as:
int array[100]; // accomodate 100 integer values
These are ok, but your requirement may be different, and you want your application to determines the size of array at runtime, so if your requirement is to use 10 elements only, that means 90 are unused but memory is still allocated for them while application is running. On other hand your application requires 110 elements to be saved, the last 10 will be unallocated spaces if array size is 100, and access to unallocated memory address may result in applciation crash and/or system level damage.

Implementing associative arrays in C/C++
This article demonstrates using string/char* indexes in regular C array, e.g. myArray["age"]=10;
We usually use numaric indexes in arrays with C and C++. But there can be another way of using C / C++ arrays like in PHP.

C Source codes
We now start some study corners, where we will try to teach some basics of the computer languages, with analyzing the programming logic and the syntaxes of the same, by providing the worked examples. Hereby we are presenting some basic worked examples, and its executable outputs of C compiler. One can find the downloadable source code and executable files packed in a .zip format in each links.
