BoundsChecker
BoundsChecker is a memory checking and API call validation tool used for C++ software development with Microsoft Visual C++. It was created by NuMega in the early 1990s. When NuMega was purchased by Compuware in 1997, BoundsChecker became part of a larger tool suite, DevPartner Studio. Micro Focus purchased the product line from Compuware in 2009. Comparable tools include Purify, Insure++ and Valgrind. BoundsChecker may be run in two distinct modes: ActiveCheck, which will work against any application as is, or FinalCheck, which makes use of instrumentation added to the application when it is built. ActiveCheck performs a less intrusive analysis and monitors all calls by the application to the C Runtime Library, Windows API and calls to COM objects. By monitoring memory allocations and releases, it can detect memory leaks and overruns. Monitoring API and COM calls enables ActiveCheck to check parameters, returns and exceptions and report exceptions when they occur. Thread dea ...

NuMega
NuMega Technologies, Inc. (also known as NuMega), was a software company founded in 1987 by Frank Grossman and Jim Moskun in Nashua, New Hampshire. The company developed a Kernel mode debugger, now SoftICE, for DOS and the Windows NT family.Mark Russinovich o#64Podnutz (2:00/1:03:09)/ref> In 1995, the company acquired the Marquis Computing, Inc. assets VB/CodeReview and VB/FailSafe, and hired its president, Hank Marquis to manage NuMega Visual Basic products. In December 1997, the company was acquired by Compuware, when it became NuMega Labs of Compuware. Less than a year after moving to Merrimack, the development lab was effectively shut down on 11 June 2007. In June 2009, Compuware sold the former NuMega products, the intellectual property and transferred the remaining staff to a UK-based firm named Micro Focus. Mark Russinovich, a software developer who now serves as CTO of Microsoft Azure, started his career at NuMega. Hank Marquis, who served as a Leadership Partner at Gar ...

Memory Leak
In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in a way that Computer memory, memory which is no longer needed is not released. A memory leak may also happen when an object (computer science), object is stored in memory but cannot be accessed by the running code (i.e. unreachable memory). A memory leak has symptoms similar to a number of other problems and generally can only be diagnosed by a programmer with access to the program's source code. A related concept is the "space leak", which is when a program consumes excessive memory but does eventually release it. Because they can exhaust available system memory as an application runs, memory leaks are often the cause of or a contributing factor to software aging. Consequences A memory leak reduces the performance of the computer by reducing the amount of available memory. Eventually, in the worst case, too much of the available memory may b ...

Memory Management
Memory management is a form of resource management applied to computer memory. The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed. This is critical to any advanced computer system where more than a single process might be underway at any time. Several methods have been devised that increase the effectiveness of memory management. Virtual memory systems separate the memory addresses used by a process from actual physical addresses, allowing separation of processes and increasing the size of the virtual address space beyond the available amount of RAM using paging or swapping to secondary storage. The quality of the virtual memory manager can have an extensive effect on overall system performance. In some operating systems, e.g. OS/360 and successors, memory is managed by the operating system. In other operating systems, e.g. Unix-like operating sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Debuggers
A debugger or debugging tool is a computer program used to test and debug other programs (the "target" program). The main use of a debugger is to run the target program under controlled conditions that permit the programmer to track its execution and monitor changes in computer resources that may indicate malfunctioning code. Typical debugging facilities include the ability to run or halt the target program at specific points, display the contents of memory, CPU registers or storage devices (such as disk drives), and modify memory or register contents in order to enter selected test data that might be a cause of faulty program execution. The code to be examined might alternatively be running on an ''instruction set simulator'' (ISS), a technique that allows great power in its ability to halt when specific conditions are encountered, but which will typically be somewhat slower than executing the code directly on the appropriate (or the same) processor. Some debuggers offer two m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Programming Tool
A programming tool or software development tool is a computer program that software developers use to create, debug, maintain, or otherwise support other programs and applications. The term usually refers to relatively simple programs, that can be combined to accomplish a task, much as one might use multiple hands to fix a physical object. The most basic tools are a source code editor and a compiler or interpreter, which are used ubiquitously and continuously. Other tools are used more or less depending on the language, development methodology, and individual engineer, often used for a discrete task, like a debugger or profiler. Tools may be discrete programs, executed separately – often from the command line – or may be parts of a single large program, called an integrated development environment (IDE). In many cases, particularly for simpler use, simple ad hoc techniques are used instead of a tool, such as print debugging instead of using a debugger, manual timing (of overal ...
