On June 12, 1972, Ken Thompson and Dennis Ritchie wrote, "the number of UNIX installations has grown to 10, with more expected." Two years later the number was 50. It is estimated that there are over 3 million UNIX systems in operation today ...

UNIX is a software system that is simple, elegant, portable, and powerful. It grew in popularity without the benefit of a large marketing organization. Programmers kept using it; big companies kept fighting it. After a decade, it was clear that the users had won. A Quarter Century of UNIX is the first book to explain this incredible success, using the words of its creators, developers, and users to illustrate how the sociology of a technical group can overwhelm the intent of multi-billion-dollar corporations. In preparing to write this book, Peter Salus interviewed over 100 of these key figures and gathered relevant information from Australia to Austria. This is the book that turns UNIX folklore into UNIX history.

The book provides the first documented history of the development of the UNIX operating system, includes interviews with over 100 key figures in the UNIX community, contains classic photos and illustrations, and explains why UNIX succeeded.


A Quarter Century of UNIX presents the history of UNIX. Based on interviews with the key software engineers who invented and built this powerful operating system, this book provides unique insight into the most important operating system in the modern computing environment.

    Highly Recommended - Until Tuesday - A Wounded Warrior and the dog who saved him.

    I've just finished reading, Until Tuesday. Now this to me is a truly wonderful and inspirational book, in fact one I would sincerely recommended to all - even those that feel they are non dog lovers! Luis Carlos Montalvan provides his readers with an honest and moving account of his experiences within a war zone, injuries incurred by this, and dealing with the horrific effects resulting in Post Traumatic Stress. Luis gives his readers real insight as to exactly how even dealing with the smallest of things every day, many of us take for granted, were for him...until Tuesday came along. Words can't describe what a blessing Tuesday was and is in Luis' every day life. Luis also tells of the problems he's had in gaining access to public transport, restaurants, grocery stores etc with Tuesday, his service dog, by his side. But, I've said enough! Please read this great book - it will give you real insight into how much value, quality and love these dogs bring to the lives of service veterans, their families and people with disabilities.

    An interesting book for those who haven't already figured out the other way of making money than the traditional way.

    Rich Dad, Poor Dad. (1997) Robert Kiyosaki. 288 pages. Robert Kiyosaki was born on April 8, 1947 in Hawaii. He finished high school and attended U.S. Merchant Marine Academy and served as a helicopter gunshot pilot during the Vietnam War. After retiring, he started small businesses and the Cashflow Technologies, Inc. is the one that now operates the Rich Dad and Cashflow brands. Cashflow is a game like monopoly where it encourages smart financial strategy. Other books include, Cashflow Quadrant: Rich Dad's Guide to Financial Freedom (2000), Rich Dad's Guide to Investing: What the Rich Invest in, That the Poor and the Middle Class Do Not! (2000), Rich Kid, Smart Kid (2001), Rich Dad's Prophecy (2002), Rich Dad's Who Took My Money: Why Slow Investors Lose and Fast Money Wins! (2004). Rich dad is Robert's best friend Mike's father and the poor dad is his biological dad. Robert compares his both dad's way of reaching success in his book. The poor dad is an very high and hard working man but not successful in terms of wealth. He falls into the category "rat race"; people doing good at school to get a good paying job, a job to pay bills, and rotating in the traditional cycle. Rich dad, doesn't see schooling as important, because it doesn't teach about the importance of life, money. Mike would say not to work for money, but to invest and be smart about taxes. Same thing my dad tells me, "don't work for some, have people work for you." I thought Robert had similar ways of looking at money as Mike, since he followed his steps. The reason why I choose to read this was to see what others see in their rich and poor dads. I could relate to Robert from head to toe, but still not sure if I want to do what I love and join the Rat Race, or follow my dad's steps. "To get over the top financially, you must read RICH DAD, POOR DAD. It's common sense and market savvy for your financial future." -Zig Ziglar, world-renowned author of God's Way Is Still the Best Way. So I get the common sense, a lot people does, but what is the key to success the common sense? This book will open your eyes, but one must have the ability to work the magic. "If you want all insider wisdom on how to personally get and STAY rich, read this book! Bribe your kids (financially if you have to) to do the same." -Mark Victor Hansen, co-author, New York Times #1 bestselling Chicken Soup for the Soul series. By reading the book, school seemed like a waste of time. What is going to happen when kids start reading it? Sure they will get inspired but most will get the wrong idea about education.

This book tells you how to teach your kid to do those things. I would love to re read this book to understand it better because you can learn a lot form this book and how to rise your kid to success.

    If you have a great understanding of this book and can teach it to you kids there is not reason why they wont find the keys to make all there dreams come truth doing the thing you child loves most

    God's Promises for Girls--review

    Rating: 4.5/5

    By Jack Countryman and Amy Parker

    On the inside:

    The book contains compilation of bible verses that talks about
    what God promises to little girls for every trouble and doubts
    they will encounter in their lives. Despite being a children's
    book i believe that the things written on the book can be applied
    to any adult situation. So why not let your little girl read this book
    and at the same time learn from it too. Let her know how important
    and special she is because someone up there a king treats her like a
    princess. Who believes that what makes a person beautiful is the
    inner being and that there is someone who will always look after
    her and love her unconditionally.

    an excerpt (one of my favorite verses)

    "You Need Comfort
    Jesus said, "Don't let your hearts be troubled.
    Trust in God. And trust in me."

    John 14:1"

    This is a promise that up to this day i
    keep and believe in.

    On the outer appearance of the book:

    For me it's brings back good memories of my childhood. The
    cover is really pleasing to eyes. The art of the book catches the
    essence of what is the written in a way that children will enjoy
    especially little girls. Really cute!

    Blink by Malcolm Gladwell

    In Blink Gladwell discusses the choices we make each day that seem to be made in an instant but aren't as simple as they seem. He goes on to talk about thin slice, which is the way that our unconscious minds can make highly accurate choices in a very short time. Throughout the book Gladwell recounts the ways in which our sociocultural context can impede our ability to benefit from the thin-slicing skill of the unconscious.
    Overall an intresting book which will get one thinking. If you are into
    psychology and the way we think this is a book for you.

    A Long Way Gone Memoirs Of A Boy Soldier

    Ishmael Beah's book "Along Way Gone Memoirs of A Boy Soldier" is a non- fiction book that is written on all the struggles he faces when he is forced into war at the age of thirteen. This book takes place in Africa. He explains the journeys and tough times that he faces when his country is caught in the middle of a war. Everything that was familiar to Ishmael was lost as the war progressed. Villages were burned, people were brutally murdered, and families were torn apart right in front of his eyes. He continually comes face to face with death. All throughout his childhood he was running for his life. Eventually he was forced to fight back against his will. This once kind hearted boy became capable of such inhuman acts. This book goes through his trials and shows how one can triumph after such traumatic and scarring events. He eventually is able to regain his humanity. I enjoyed this book because in the end he was saved from this terrifying life he couldn't escape. Ishmael's description makes the book so much more real. It was well written and ends with hope. If you like happy endings in real life events, then this book is for you, because it is hopeful and uplifting. It shows good can come from bad.
