FreeCAD. Solid Modeling with the power of Python with this book and
Brad Collette, Daniel Falck
FreeCAD is a general purpose platform for CAD development. It can be extended to use different workbenches to solve different problems. Targeted squarely at the engineering community, FreeCAD is an open source design application built to be extended. Python, the powerful scripting language, is woven deeply into FreeCAD's DNA and gives users unprecedented power to automate and invent. FreeCAD [How-to] is a lean, fast tour of FreeCAD's major workbenches and design philosophy. The reader will get a hands-on introduction to several modeling techniques and learn how Python makes macro automation and design possible.FreeCAD allows users to design in a variety of ways; from drawing 2D designs as lines and circles to combining primitive solids into complex 3D shapes. Objects can even be created or modified by code you write in Python. FreeCAD even allows power users to extend the application itself with new dialogs, panels, and scripts. This book will not only show you how to get started using FreeCAD in a traditional GUI mode, but will teach you how to harness its powerful scripting language for more power.

The Open Source pioneers have proved during the past few decades that their code and projects can indeed be more solid and popular than commercial alternatives. With data networks always expanding in size and complexity FreeRADIUS is at the forefront of controlling access to and tracking network usage. Although many vendors have tried to produce better products, FreeRADIUS has proved over time why it is the champion RADIUS server. This book will reveal everything you need to know to get started with using FreeRADIUS.FreeRADIUS has always been a back-room boy. It's not easy to measure the size or number of deployments world-wide but all indications show that it can outnumber any commercial alternatives available. This essential server is part of ISPs, universities, and many corporate networks, helping to control access and measure usage. It is a solid, flexible, and powerful piece of software, but can be a mystery to a newcomer.FreeRADIUS Beginner's Guide is a friend of newcomers to RADIUS and FreeRADIUS. It covers the most popular Linux distributions of today, CentOS, SUSE, and Ubuntu, and discusses all the important aspects of FreeRADIUS deployment: Installing, configuring and testing; security concerns and limitations; LDAP and Active Directory integration.It contains plenty of practical exercises that will help you with everything from installation to the more advanced configurations like LDAP and Active Directory integration. It will help you understand authentication, authorization and accounting in FreeRADIUS. It uses many practical step-by-step examples, which are discussed in detail to lead you to a thorough understanding of the FreeRADIUS server as well as the RADIUS protocol. A quiz at the end of each chapter validates your understanding.Not only can FreeRADIUS be used to monitor and limit the network usage of individual users; but large deployments are possible with realms and fail-over functionality. FreeRADIUS can work alone or be part of a chain where the server is a proxy for other institution's users forwarding requests to their servers. FreeRADIUS features one of the most versatile and comprehensive Extensible Authentication Protocol (EAP) implementations. EAP is an essential requirement to implement enterprise WiFi security. FreeRADIUS Beginner's Guide covers all of these aspects.
