URBAN RETRIBUTION A powerful Colombian cartel goes too far when they torture and kill a DEA agent. Tasked with dismantling their operation and taking out their leader, Mack Bolan heads to Cali with an unlikely ally—a convicted murderer known as the Witch. The former cocaine dealer has an axe to grind with the cartel's kingpin, and she's willing to go along with Bolan's plan as long as they avenge her sons' deaths in the process. But sending the woman in as bait works too well. Outnumbered and outgunned, the two will need more than their combat skills to dodge the bullets. If they're going to survive this Colombian street war, they'll have to trust each other and work as a team, even when it seems the end is near. The cartel may fear the Witch's revenge, but the Executioner will make them dread justice.
Providing in-depth treatment of error correction Error Correction Coding: Mathematical Methods and Algorithms, 2nd Edition provides a comprehensive introduction to classical and modern methods of error correction. The presentation provides a clear, practical introduction to using a lab-oriented approach. Readers are encouraged to implement the encoding and decoding algorithms with explicit algorithm statements and the mathematics used in error correction, balanced with an algorithmic development on how to actually do the encoding and decoding. Both block and stream (convolutional) codes are discussed, and the mathematics required to understand them are introduced on a “just-in-time” basis as the reader progresses through the book. The second edition increases the impact and reach of the book, updating it to discuss recent important technological advances. New material includes: Extensive coverage of LDPC codes, including a variety of decoding algorithms. A comprehensive introduction to polar codes, including systematic encoding/decoding and list decoding. An introduction to fountain codes. Modern applications to systems such as HDTV, DVBT2, and cell phones Error Correction Coding includes extensive program files (for example, C++ code for all LDPC decoders and polar code decoders), laboratory materials for students to implement algorithms, and an updated solutions manual, all of which are perfect to help the reader understand and retain the content. The book covers classical BCH, Reed Solomon, Golay, Reed Muller, Hamming, and convolutional codes which are still component codes in virtually every modern communication system. There are also fulsome discussions of recently developed polar codes and fountain codes that serve to educate the reader on the newest developments in error correction.
ALL BETS ARE OFF Nine million dollars goes missing from a Vegas casino, and accountant Harry Sherman becomes the mob's scapegoat. Sherman's ready to spill everything to the Feds in exchange for his freedom, but his bosses are determined to shut him up--forever. Protecting the moneyman proves too much for the Justice Department, leaving only one guy for the job: Mack Bolan. Soon, Bolan's racing across the country to secure the fugitive Sherman before a team of hired killers catches up to him. Time is tight as every clue to the desperate man's whereabouts leads to a dead body and puts innocent lives in the line of fire. But when it comes to justice, the Executioner always has another card up his sleeve--and he'll aim it straight at the enemy.

If you're seeking a job-based certification from the Linux Professional Institute (LPI), this updated guide will help you prepare for the technically challenging LPIC Level 1 Exams 101 and 102. The third edition of this book is a meticulously researched reference to these exams, written by trainers who work closely with LPI. You'll find an overview of each exam, a summary of the core skills you need, review questions and exercises, as well as a study guide, a practice test, and hints to help you focus. Major topics include: Critical GNU and Unix commands Linux installation and package management Devices and filesystems Text editing, processing, and printing The X Window System Networking and security Mail transfer agents Email, FTP, and web services These exams are for junior to mid-level Linux administrators with about two years of practical system administration experience. You should be comfortable with Linux at the command line and capable of performing simple tasks, including system installation and troubleshooting.
CRIMEAN DEADLOCK Ukrainian militants are the initial suspects in a terrorist attack on Washington, DC, until rumors surface suggesting Moscow was behind the bombing. But the investigation only raises more questions. Was the attack an attempt to mute US criticism of Russia, or a call to action to help suppress Ukrainian dissidents? Only one man can solve the riddle and mete out appropriate punishment: Mack Bolan. From Manhattan's Little Ukraine to the war-torn country itself, Bolan blazes a path of truth and justice to neutralize the threat…and prevent another slaughter on American soil even as the danger increases with enemies and allies emerging on both sides of the Crimean conflict. But the Executioner is no middleman; he has his own war to fight, and he won't stop until his opponents are ashes.
REVENGE STRIKE Within hours, several of Chicago’s finest police officers are dead in a violent killing spree. But Mack Bolan is certain these murders aren’t random—or anywhere near finished. It doesn’t take long for him to hone in on Shalib Grec, a terrorist smuggler whose brother died at the hands of police. Grec has vowed revenge, and only The Executioner stands in his way. Now Bolan must turn Grec’s empire against him and evade the terrorist’s expert assassins to deliver final, merciless justice.
