Quotes About Threads

My writing process is chaos. I usually start with an overarching theme. Then I establish several story threads, but I don't outline. I just start writing and keep notes for what may come. It's an organic process that's usually pretty flexible.

An action movie should, like any other, follow the narrative traditions of literature. That means there should be subtlety, a slow build and a gradual bringing together of all the separate threads of the plot. To see all of it coming together slowly is very rewarding for the audience.

Like delicate lace, So the threads intertwine, Oh, gossamer web Of wond'rous design! Such beauty and grace Wild nature produces... Ughh, look at the spider Suck out that bug's juices!

the cow crossly shook her head and craned her neck, mooing plaintively, and beyond the black barns of Meliuzeievo the stars twinkled, and invisible threads of sympathy stretched between them and the cow as if there were cattle sheds in other worlds where she was pitied. Everything

Translation is always a treason, and as a Ming author observes, can at its best be only the reverse side of a brocade- all the threads are there, but not the subtlety of colour or design.

Experience is never limited, and it is never complete; it is an immense sensibility, a kind of huge spider-web, of the finest silken threads, suspended in the chamber of consciousness and catching every air-borne particle in its tissue.

La experiencia no es nunca limitada, y no es jamás completa; es una sensibilidad inmensa, una especie de enorme tela de araña de los más finos hilos de seda suspendida en la cámara de la conciencia, y que capta en su tejido todas las particularidades llevadas por el aire.

There was a rightness to things that surpassed understanding, but she knew beyond all doubt that in each and every circumstance her feet had been guided along this path and to this place. A favourite saying in China—which she had heard on occasion from her own grandmother—was that the threads of life are easy to weave, but difficult to untangle.

which is a unique numeric identifier. A process contains one or more threads, which operate in the process address space and share the same file descriptors (state describing open files).

Whenever more than one thread accesses a given state variable, and one of them might write to it, they all must coordinate their access to it using synchronization.

When a field is declared volatile, the compiler and runtime are put on notice that this variable is shared and that operations on it should not be reordered with other memory operations. Volatile variables are not cached in registers or in caches where they are hidden from other processors, so a read of a volatile variable always returns the most recent write by any thread.

The possibility of incorrect results in the presence of unlucky timing is so important in concurrent programming that it has a name: a race condition. A race condition occurs when the correctness of a computation depends on the relative timing or interleaving of multiple threads by the runtime; in other words, when getting the right answer relies on lucky timing.

With the exception of immutable objects, it is not safe to use an object that has been initialized by another thread unless the publication happens-before the consuming thread uses it.

it is a common misconception that synchronized is only about atomicity or demarcating "critical sections". Synchronization also has another significant, and subtle, aspect: memory visibility. We want not only to prevent one thread from modifying the state of an object when another is using it, but also to ensure that when a thread modifies the state of an object, other threads can actually see the changes that were made.

When used properly, threads can reduce development and maintenance costs and improve the performance of complex applications.

always use the proper synchronization whenever data is shared across threads. 3.1.1.

But our long struggle is held together by the slender threads of heroes and myths.

Locking is not just about mutual exclusion; it is also about memory visibility. To ensure that all threads see the most up-to-date values of shared mutable variables, the reading and writing threads must synchronize on a common lock.

Just as tasks should have a cancellation policy, threads should have an interruption policy.

A race condition occurs when the correctness of a computation depends on the relative timing or interleaving of multiple threads by the runtime; in other words, when getting the right answer relies on lucky timing.

When a thread requests a lock that is already held by another thread, the requesting thread blocks. But because intrinsic locks are reentrant, if a thread tries to acquire a lock that it already holds, the request succeeds. Reentrancy means that locks are acquired on a per-thread rather than per-invocation basis.

The other end-run around the need to synchronize is to use immutable objects [EJ Item 13]. Nearly all the atomicity and visibility hazards we've described so far, such as seeing stale values, losing updates, or observing an object to be in an inconsistent state, have to do with the vagaries of multiple threads trying to access the same mutable state at the same time. If an object's state cannot be modified, these risks and complexities simply go away. An

This warp seemed necessity; and here, thought I, with my own hand I ply my own shuttle and weave my own destiny into these unalterable threads.

That is the god's work, spinning threads of death through the lives of mortal men, and all to make a song for those to come...
