Bad Gateway

Owl is gone, Werewolf Jones has moved in, and everything as Megg and Mogg know it begins to fall apart. Hanselmann’s comic premise of his previous graphic novels ― eternally stoned, slacker roommates ― stretches at the seams as his characters reflect the psychological toll that their years of unsustainable, determined insouciance and self-medication has inflicted.

This cutting-edge book shows you how SIP provides a highly-scalable and cost-effective way to offer new and exciting telecommunication feature sets, helping you design your OC next generationOCO network and develop new applications and software stacks. Other key discussions include SIP as a key component in the Internet multimedia conferencing architecture, request and response messages, devices in a typical network, types of servers, SIP headers, comparisons with existing signaling protocols including H.323, related protocols SDP (Session Description Protocol) and RTP (Real-time Transport Protocol), and the future direction of SIP. Detailed call flow diagrams illustrate how this technology works with other protocols such as H.323 and ISUP. Moreover, this book covers SIP RFC 3261 and the complete set of SIP extension RFCs."

Megg the witch, Mogg the cat, their friend Owl, and Werewolf Jones struggle unsuccessfully with their depression, drug use, sexuality, poverty, lack of ambition, and their complex feelings about each other. It’s a laff riot! Megg and Mogg decide to take a trip to Amsterdam for some quality couple time, although the trip gets off to a rocky start when they forget their antidepressants. They need Owl to come and help them save their relationship. But why does he have a suitcase full of glass dildos? And what will they do when they realize that the housesitting Werewolf Jones has turned their apartment into a “f#@k zone”? Megg & Mogg in Amsterdam collects all of Simon Hanselmann’s contributions to Vice.com, the Ignatz Award-nominated short story “St. Owl’s Bay,” and other surprises that will add additional color and background for fans of Megahex.

Make the best of your test suites by using cutting-edge software architecture patterns in Python Key FeaturesLearn how to create scalable and maintainable applicationsBuild a web system for micro messaging using concepts in the bookUse profiling to find bottlenecks and improve the speed of the systemBook Description Developing large-scale systems that continuously grow in scale and complexity requires a thorough understanding of how software projects should be implemented. Software developers, architects, and technical management teams rely on high-level software design patterns such as microservices architecture, event-driven architecture, and the strategic patterns prescribed by domain-driven design (DDD) to make their work easier. This book covers these proven architecture design patterns with a forward-looking approach to help Python developers manage application complexity—and get the most value out of their test suites. Starting with the initial stages of design, you will learn about the main blocks and mental flow to use at the start of a project. The book covers various architectural patterns like microservices, web services, and event-driven structures and how to choose the one best suited to your project. Establishing a foundation of required concepts, you will progress into development, debugging, and testing to produce high-quality code that is ready for deployment. You will learn about ongoing operations on how to continue the task after the system is deployed to end users, as the software development lifecycle is never finished. By the end of this Python book, you will have developed "architectural thinking": a different way of approaching software design, including making changes to ongoing systems. What you will learnThink like an architect, analyzing software architecture patternsExplore API design, data storage, and data representation methodsInvestigate the nuances of common architectural structuresUtilize and interoperate elements of patterns such as microservicesImplement test-driven development to perform quality code testingRecognize chunks of code that can be restructured as packagesMaintain backward compatibility and deploy iterative changesWho this book is for This book will help software developers and architects understand the structure of large complex systems and adopt architectural patterns that are scalable. Examples in the book are implemented in Python so a fair grasp of basic Python concepts is expected. Proficiency in any programming languages such as Java or JavaScript is sufficient.

This book addresses researchers and graduate students at the forefront of study/research on the Internet of Things (IoT) by presenting state-of-the-art research together with the current and future challenges in building new smart applications (e.g., Smart Cities, Smart Buildings, and Industrial IoT) in an efficient, scalable, and sustainable way. It covers the main pillars of the IoT world (Connectivity, Interoperability, Discoverability, and Security/Privacy), providing a comprehensive look at the current technologies, procedures, and architectures.

Megg is a depressed, drug-addicted witch. Mogg is her black cat. Their friend, Owl, is an anthropomorphized owl. They hang out a lot with Werewolf Jones. This may sound like a pure stoner comedy, but it transcends the genre: these characters struggle unsuccessfully to come to grips with their depression, drug use, sexuality, poverty, lack of work, lack of ambition, and their complex feelings about each other in ways that have made Megg and Mogg sensations on Hanselmann's GirlMountain tumblr. This is the first collection of Hanselmann's work, freed from its cumbersome Internet prison, and sure to be one of the most talked about graphic novels of 2014, featuring all of the “classic” Megg and Mogg episodes from the past five years as well as over 70 pages of all-new material.

Cyber Operations walks you through all the processes to set up, defend, and attack computer networks. This book focuses on networks and real attacks, offers extensive coverage of offensive and defensive techniques, and is supported by a rich collection of exercises and resources. You'll learn how to configure your network from the ground up, starting by setting up your virtual test environment with basics like DNS and active directory, through common network services, and ending with complex web applications involving web servers and backend databases. Key defensive techniques are integrated throughout the exposition. You will develop situational awareness of your network and will build a complete defensive infrastructure—including log servers, network firewalls, web application firewalls, and intrusion detection systems. Of course, you cannot truly understand how to defend a network if you do not know how to attack it, so you will attack your test systems in a variety of ways beginning with elementary attacks against browsers and culminating with a case study of the compromise of a defended e-commerce site. The author, who has coached his university’s cyber defense team three times to the finals of the National Collegiate Cyber Defense Competition, provides a practical, hands-on approach to cyber security.
