Book Description
Computers are just as busy as the rest of us nowadays. They have lots of tasks to do at once, and need some cleverness to get them all done at the same time.That's why threads are seen more and more often as a new model for programming. Threads have been available for some time. The Mach operating system, the Distributed Computer Environment (DCE), and Windows NT all feature threads.One advantage of most UNIX implementations, as well as DCE, is that they conform to a recently ratified POSIX standard (originally 1003.4a, now 1003.1c), which allows your programs to be portable between them. POSIX threads are commonly known as pthreads, after the word that starts all the names of the function calls. The standard is supported by Solaris, OSF/1, AIX, and several other UNIX-based operating systems.The idea behind threads programming is to have multiple tasks running concurrently within the same program. They can share a single CPU as processes do, or take advantage of multiple CPUs when available. In either case, they provide a clean way to divide the tasks of a program while sharing data.A window interface can read input on dozens of different buttons, each responsible for a separate task. A network server has to accept simultaneous calls from many clients, providing each with reasonable response time. A multiprocessor runs a number-crunching program on several CPUs at once, combining the results when all are done. All these kinds of applications can benefit from threads.In this book you will learn not only what the pthread calls are, but when it is a good idea to use threads and how to make them efficient (which is the whole reason for using threads in the first place). The authors delves into performance issues, comparing threads to processes, contrasting kernel threads to user threads, and showing how to measure speed. He also describes in a simple, clear manner what all the advanced features are for, and how threads interact with the rest of the UNIX system.Topics include: Basic design techniques Mutexes, conditions, and specialized synchronization techniques Scheduling, priorities, and other real-time issues Cancellation UNIX libraries and re-entrant routines Signals Debugging tips Measuring performance Special considerations for the Distributed Computing Environment (DCE)

Book Description
The Southern Sewing Circle mystery series continues. Yankee librarian Tori Sinclair is basking in the warmth of her new circle of friends from South Carolina's Sweet Briar Ladies Society sewing circle. That is until local author Colby Calhoun reveals an unflattering secret about the town's historic past-and then disappears, leaving a bloody trail behind him. And when Tori begins to see a pattern of the townsfolk's age-old Southern pride standing in the way of justice, she knows it's time to unravel the mystery.

Book Description
The fourth book in the “outstanding” (Romantic Times) Elemental Assassin fantasy series featuring Gin Blaco, who by day is a waitress at a Tennessee BBQ joint, and by night is a tough female assassin. I’d rather face a dozen lethal assassins any night than deal with something as tricky, convoluted, and fragile as my feelings. But here I am. Gin Blanco, the semi-retired assassin known as the Spider. Hovering outside sexy businessman Owen Grayson’s front door like a nervous teenage girl. One thing I like about Owen: he doesn’t shy away from my past—or my present. And right now I have a bull’s-eye on my forehead. Cold-blooded Fire elemental Mab Monroe has hired one of the smartest assassins in the business to trap me. Elektra LaFleur is skilled and efficient, with deadly electrical elemental magic as potent as my own Ice and Stone powers. Which means there’s a fifty-fifty chance one of us won’t survive this battle. I intend to kill LaFleur—or die trying—because Mab wants the assassin to take out my baby sister, Detective Bria Coolidge, too. The only problem is, Bria has no idea I’m her long-lost sibling . . . or that I’m the murderer she’s been chasing through Ashland for weeks. And what Bria doesn’t know just might get us both dead. . . .

Book Description
Seeing the future is hard, but facing it will be explosive A Seer has surfaced—but she’s blind! Chloe Santos is an immortal with a whole world of problems. The victim of an attempted murder that left her blind, horribly disfigured, and stuck with powers everyone thought eradicated, it’s safe to say she’s at a low point in her life. But then she’s blackmailed into investigating a kidnapping with links to her past. It could put herself, and everyone she cares about, in danger. Including her Warrior Soulmate. Phobos has a millennia of blood on his hands. As the son of Ares, he’s done horrific things in the name of keeping the continued existence of immortals a secret. Only all of that changes when he meets his Soulmate. Allegiances shift, trust is thin and Chloe has to decide if she should risk everything to make the world a better place. Even if that means sacrificing her own chance at happiness. READER ADVISORY: This Paranormal Romance contains a strong-willed goddess and her protective Warrior Soulmate who don’t appreciate the term ‘vanilla’ when it comes to the bedroom.

Book Description
The Odyssey is the original journey tale, a genre that has lasted three thousand years, and has had a lasting influence on on literature and art. The trials of Odysseus were first told by the great bard Homer. For ten long years the Greeks and Trojans have fought on the plains of Troy, and now Odysseus, the King of Ithaca, and the other victorious Greeks are ready to sail home. But after offending the sea god, Poseidon, Odysseus is hurled into years of wandering the seas, encountering monsters and sirens, raging storms and seductive idylls, before he is able to return to his wife, his son and his homeland. This masterpiece keeps its appeal not only because it reflects a glorious time of heroes and wonders, but because it is a work that still speaks to the lives we live today. Forge book is proud to present The Odyssey in Dr. Eickhoff's compelling and authoritative new translation. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Book Description
Dr Monareng believes that there are rays of hope even during the darkest hours of our lives. Hope gives us zeal and courage to believe that things will be better one day. We are in the world that is full of lies and lacks forgiveness. The world that has become an employer to the human race. In this fascinating journey of life, elders need to pass on a baton to the younger generation with the hope that norms and values of the past remain immortal. The twenty-first-century parents should apply the relevant parenting style. Our lives have an impact on the lives of our followers in this world. Be brave and be a conqueror who is not a fake but is him/herself. We must be remembered even long after our deaths. Swim through the storms of life and make peace with the past in order to enjoy the present.
