Topic: Thread computer programming

	What is thread-safe? - a definition from Whatis.com
		(A thread is an instance of the program running on behalf of some user or process.) Thread safety is of particular importance to Java programmers, since Java is a programming language that provides built-in support for threads.
		By using thread-safe routines, the risk that one thread will interfere and modify data elements of another thread is eliminated by circumventing potential data race situations with coordinated access to shared data.
		Confining the address of a shared object to one thread whenever an unsynchronized algorithm is active..

	Encyclopedia: Thread (computer programming)
		Threads are similar to processes, in that both represent a single sequence of instructions executed in parallel with other sequences, either by time slicing or multiprocessing.
		Threads are distinguished from traditional multi-tasking operating system processes in that processes are typically independent, carry considerable state information, have separate address spaces, and interact only through system-provided inter-process communication mechanisms.
		Threads are used to enable a program to render its graphical user interface while waiting for input from the user or performing a task like spell checking.

	The Temporal Doorway - Thread Basics
		As long as the two programs share no data, this is perfectly safe, and, just as television or an animation provides the illusion of movement by flashing single frames faster than the eye and mind can distinguish, time-slicing makes it look as if two or more programs are running at the same time.
		Once the first thread enters the critical section, subsequent threads attempting to execute code within the critical section (which requires them to execute TCriticalSection::Enter) are queued and do not proceed until the first thread is finished with the critical section (by calling TCriticalSection::Leave).
		Threads are not terribly complex to set up, but understanding their implications requires careful thought.

	Steve Jackson Games Forums - Computer Programming and Mathematical Ability
		While at it's core programming may be all ones and zeroes, but to me that's just as abstract as the way, at their core, people are just atoms and nothingness.
		I think it's important to note that what constitutes a 'computer programmer' in 2005 is very different from what a 'computer programmer' was 20, 30, or even 50 years ago.
		Computer programming is full of fuzzy stuff, soft rules, exceptions, etc. Although the execution of one particular instruction will always yield the same result under the same circumstances, the assembling of those instructions to give a particular result stays open to interpretation and errors.

	Writing multithreaded Java applications
		The OS can move threads from the processor to either a ready or blocking queue, in which case the thread is said to have "yielded" the processor.
		Threads that attempt to acquire a lock in use go to sleep until the thread holding the lock releases it.
		Threads that attempt to acquire a semaphore when all the resources managed by the semaphore are in use simply block until a resource is free.

	Java Threads
		Thread of control sounds like a complicated technical term, but it's really a simple concept: it is the path taken by a program during execution.
		For one of the threads in the program, that location is the main() method; for the rest of the threads, it is a particular location the programmer decides upon when the code is written.
		Exploiting those methods of co- operation is the reason why programming with threads is such a useful technique, but that cooperation is completely optional, much as the user is never required to drag a file from the file manager into the text editor.

	Thread Programming
		This happens when several threads are suspended until it can gain control of the same object, and each one has a lock on another resource that they need in order to proceed with the processing.
		Anita Mary Joseph notes in Thread Communication Using Wait(), Pulse() and PulseAll() that "often the cause of the deadlock is not readily understood just by looking at the source code of the program, because concurrently executing threads can interact in complex ways at runtime.
		A thread does not respond to interrupts when it is blocked waiting to acquire exclusive access to a synchronized lock.

	Thread Programming With Python
		The sharing of memory between threads allows faster and more fine-grained communication between threads: threads can communicate by exchanging a pointer to a data structure in memory, while separate processes need to serialize data to a file or buffer in order to pass it to each other.
		Unfortunately the operating system is oblivious to the task that a thread is trying to accomplish, and may switch to another thread at an arbitrary point in the middle of that task.
		It is entered by different threads at different times, but because the acquire() method only allows one thread to continue at a time, there will never be more than one thread executing in the critical section.

	Thread
		When talking about computer programming or software, a thread is a portion of a program that is executed in conjunction with the main program that performs another task.
		For example, a program may have an open thread waiting for a specific event to occur or may have a thread running a separate job, allowing for the main program to perform other tasks.
		A program is capable of having multiple threads open at once and will either terminate or suspend the thread when the thread's task is complete or the program is closed.

	Linux Tutorial: POSIX Threads
		Threads require less overhead than "forking" or spawning a new process because the system does not initialize a new system virtual memory space and environment for the process.
		A race condition often occurs when two or more threads need to perform operations on the same memory area, but the results of computations depends on the order in which these operations are performed.
		A condition variable must always be associated with a mutex to avoid a race condition created by one thread preparing to wait and another thread which may signal the condition before the first thread actually waits on it resulting in a deadlock.

	Diagnosing Java Code: The Orphaned Thread bug pattern
		The Java programming language provides abundant support for multithreaded code, including one feature that can be especially useful: the ability to throw an exception in one thread without affecting the others.
		In a case such as this, the second thread is entirely dependent upon the first to receive any data with which to compute.
		Cause: Various program threads are stuck waiting for input from a thread that exited after an uncaught exception was thrown.

		The machine-independent thread package described here is written in C and may be incorporated into C or C++ programs to allow use of non-preemptive multithreaded programming.
		Threads may perform any computation, call any procedures, or address any static variables in the program, so long as the dynamic storage requirement for automatic variables and procedure linkage does not overflow the stack of the calling thread.
		This thread package is intended as the base for student assignments in an introductory operating system class with where the emphasis is on how processes are implemented on a uniprocessor.
