So, you're one of the many, the proud... the Unix geeks who've "switched" to Mac OS X. Although hacking code on the Mac is the same as hacking code on other Unix systems, you're bound to run into some problems because of the subtle differences between the Unix you're accustomed to and how things are done in Mac OS X 10.2 (Jaguar). Mac OS X for Unix Geeks was written by two long-time Unix users who've found themselves exactly where you are. It cuts through the chaff and gets right to the point on such topics as : • Using the Terminal and understanding how it differs from an xterm • Using Directory Services, Open Directory (LDAP), and NetInfo • Compiling code with GCC 3 • Library linking and porting Unix software • Creating and installing packages with Fink • Building the Darwin kernel • Running X Windows on top of Mac OS X This quick and dirty guide continues with an overview of Mac OS X's filesystem and startup processes, wrapping up with a handy reference section called the "Missing Manpages", covering Mac OS X commandline utilities not in the official documentation. Mac OS X is quickly becoming the platform of choice for Unix hackers and geeks, because it gives you what Tim O'Reilly refers to as "guilt-free computing"- a Unix system that you don't have to share with Windows. If you proudly wear the badge "Unix Geek", this book is your guide to demystifying the geekier side of Mac OS X.

From the outside, Vanya’s childhood looked idyllic… WINNER, 2019 Next Generation Indie Books (Memoir: Overcoming Adversity) She rode horses with her father in the solitude of the Sierra Nevada Mountains and attended flamboyant operas with her mother in the city. But life for Vanya and her family turned dark when ghosts from her father’s service on a Pacific destroyer in World War II tore her family apart. Set in postwar California, this is the story of a girl who tried to make sense of her parents’ unpredictable actions—from being left to lie in her own blood-soaked diaper while her Christian Scientist mother prayed, to refusing to get medical help while watching her father writhe on his bed in the detox ward, his hands and feet tethered with leather straps—by immersing herself in the beauty and solitude of the wilderness around her. It was only decades later when memories began to haunt her, that Vanya was able to look back with unflinching honesty and tender compassion for her family and herself. Boot Language shines a light in the darkness so that others can find their way This spellbinding memoir offers encouragement and hope to those who are: in a dysfunctional family, experiencing or navigating emotional abuse, in a relationship with an abused partner or child, or simply looking to find happiness in spite of their past. Erickson’s story shines a light in the darkness so that others can find their way to heal the past. In this elegant, haunting narrative, she invites us to witness it all—from the gripping, often disturbing, truths of her childhood to her ultimate survival. Boot Language uplifts the reader with the knowledge that it is your responses to life’s adverse circumstances that make all the difference; and that by facing your past you can find the inner strength to permanently discover that you can transform your life. While Erickson’s memories would never completely disappear, they no longer held her in their grip. They have importance. They became an integral part of her life, leading her to become a successful teacher, author, and speaker, helping countless women and teens come to terms with their past.
