Asterisk has a wealth of features to help you customize your PBX to fill very specific business needs. This short cookbook offers recipes for tackling dialplan fundamentals, making and controlling calls, and monitoring channels in your PBX environment. Each recipe includes a simple code solution you can put to work immediately, along with a detailed discussion that offers insight into why and how the recipe works. This book focuses on Asterisk 1.8, although many of the conventions and information presented are version-agnostic. These recipes include solutions to help you: Authenticate callers before moving on in your dialplan Redirect calls received by your auto-attendant Create an automatic call-back service Initiate hot-desking to login to and accept calls at any office device Monitor and interrupt live calls to train new employees at a call center Record calls from your Asterisk dialplan

Complete Asterisk Training is a new edition of the Configuration Guide for Asterisk PBX. The reason for change the name is to match the name of the online training available on Udemy. So this book is part of a three part training system, eLearning, Text Book and Lab Guide. Why a different book about Asterisk? Most books are not oriented to teach the reader on how to build a complete PBX. They present many concepts, but not with a story, an objective. I have based this book in the old training guides from Novell. So it has a start where you install Asterisk, then you create extensions, trunks, dialplan until you complete a fully functional free and open source PBX. Then we go to more advanced concepts. In this book you will learn: - How to install Asterisk- How to register extensions- How to connect SIP trunks- How to create a dial plan to send and receive calls- How to configure analog and digital channels- How to configure SIP, IAX and PJSIP- How to use Asterisk behind NAT and clients behind NAT- How to use PBX features such as tranfer, capture, parking, conference- How to configure Call queues and Agents - How to generate CDRs to a database using ODBC drivers- How to develop simple AGIs and AMIs to connect your programs- How to secure Asterisk using Fail2Ban, IPTABLES, TLS and SRTP- How to use Asterisk Real Time to read the configuration from a databaseWe cover the latest version, Asterisk 16, a Long Term Support version. I hope you use this version for a long time. This book has more than 10 years, the first edition was in 2006 and since then it has been updated once each 4 or 5 years. This book has two companions. A training on Udemy with the same name and a Lab Guide on github, more details inside the book . I sincerely hope you enjoy. Flavio E. Goncalves

Ready to unlock the power of your data? With this comprehensive guide, you’ll learn how to build and maintain reliable, scalable, distributed systems with Apache Hadoop. This book is ideal for programmers looking to analyze datasets of any size, and for administrators who want to set up and run Hadoop clusters. You’ll find illuminating case studies that demonstrate how Hadoop is used to solve specific problems. This third edition covers recent changes to Hadoop, including material on the new MapReduce API, as well as MapReduce 2 and its more flexible execution model (YARN). Store large datasets with the Hadoop Distributed File System (HDFS) Run distributed computations with MapReduce Use Hadoop’s data and I/O building blocks for compression, data integrity, serialization (including Avro), and persistence Discover common pitfalls and advanced features for writing real-world MapReduce programs Design, build, and administer a dedicated Hadoop cluster—or run Hadoop in the cloud Load data from relational databases into HDFS, using Sqoop Perform large-scale data processing with the Pig query language Analyze datasets with Hive, Hadoop’s data warehousing system Take advantage of HBase for structured and semi-structured data, and ZooKeeper for building distributed systems

This book is the definitive guide to SQL*Plus. If you want to take best advantage of the power and flexibility of this popular Oracle tool, you need this book. SQLPlus is an interactive query tool that is ubiquitous in the Oracle world. It is present in every Oracle installation and is available to almost every Oracle developer and database administrator. SQLPlus has been shipped with Oracle since at least version 6. It continues to be supported and enhanced with each new version of Oracle, including Oracle8 and Oracle8i. It is still the only widely available tool for writing SQL scripts. Despite this wide availability and usage, few developers and DBAs know how powerful SQL*Plus really is. This book introduces SQLPlus, includes a quick reference to all of its syntax options, and, most important, provides chapters that describe, in step-by-step fashion, how to perform all of the tasks that Oracle developers and DBAs want to perform with SQLPlus -- and maybe some they didn't realize they COULD perform with SQLPlus. You will learn how to write and execute script files, generate ad hoc reports, extract data from the database, query the data dictionary tables, customize your SQLPlus environment, and use the SQL*Plus administrative features (new in Oracle8i). This book is an indispensable resource for readers who are new to SQL*Plus, a task-oriented learning tool for those who are already using it, and a quick reference for every user. A table of contents follows: Preface Introduction to SQLPlus Interacting with SQLPlus Generating Reports with SQLPlus Writing SQLPlus Scripts Extracting Data with SQLPlus Exploring Your Database with SQLPlus Advanced Scripting Tuning and Timing The Product User Profile Administration with SQLPlus Customizing Your SQLPlus Environment Appendices A.

Grammar has finally let its hair down! Unlike uptight grammar books that overwhelm us with every single grammar rule, Kiss My Asterisk is like a bikini: it’s fun, flirty, and covers only the most important bits. Its lessons, which are 100 percent free of complicated grammar jargon, have been carefully selected to include today’s most common, noticeable errors—the ones that confuse our readers or make them wonder if we are, in fact, smarter than a fifth grader. What is the proper use of an apostrophe? When should an ellipsis be used instead of an em dash? Why do we capitalize President Obama but not “the president”? And why is that question mark placed outside of the end quote? Author Jenny Baranick is an English professor whose students can’t believe she’s actually that into grammar. Upon experiencing the joys of grammar at an early age, raising grammar awareness became Jenny’s raison d’être. By spreading her remarkably user-friendly and hilarious approach to grammar, she hopes everyone will experience the satisfaction of a properly placed comma, a precisely used semicolon, and a correctly deployed en dash. Kiss My Asterisk shows grammar as it’s never been seen before: uncomplicated, laugh-out-loud funny, and, dare we say, a little risqué.
