"FreeIPA is an integrated security information management solution combining Linux (Fedora), 389 Directory Server, MIT Kerberos, NTP, DNS, Dogtag (Certificate System). It consists of a web interface and command-line administration tools. FreeIPA is an integrated Identity and Authentication solution for Linux/UNIX networked environments. A FreeIPA server provides centralized authentication, authorization and account information by storing data about user, groups, hosts and other objects necessary to manage the security aspects of a network of computers. FreeIPA is built on top of well known Open Source components and standard protocols with a very strong focus on ease of management and automation of installation and configuration tasks. Multiple FreeIPA servers can easily be configured in a FreeIPA Domain in order to provide redundancy and scalability. The 389 Directory Server is the main data store and provides a full multi-master LDAPv3 directory infrastructure. Single-Sign-on authentication is provided via the MIT Kerberos KDC. Authentication capabilities are augmented by an integrated Certificate Authority based on the Dogtag project. Optionally Domain Names can be managed using the integrated ISC Bind server. Security aspects related to access control, delegation of administration tasks and other network administration tasks can be fully centralized and managed via the Web UI or the ipa Command Line tool."

"FreeIPA allows Linux administrators to centrally manage identity, authentication and access control aspects of Linux and UNIX systems by providing simple to install and use command line and web based management tools. FreeIPA is built on top of well known Open Source components and standard protocols with a very strong focus on ease of management and automation of installation and configuration tasks. FreeIPA can seamlessly integrate into an Active Directory environment via cross-realm Kerberos trust or user synchronization. Benefits FreeIPA: Allows all your users to access all the machines with the same credentials and security settings Allows users to access personal files transparently from any machine in an authenticated and secure way Uses an advanced grouping mechanism to restrict network access to services and files only to specific users Allows central management of security mechanisms like passwords, SSH Public Keys, SUDO rules, Keytabs, Access Control Rules Enables delegation of selected administrative tasks to other power users Integrates into Active Directory environments"

A collection of MapReduce tasks translated (from Pig, Hive, MapReduce streaming, etc.) into Scalding for comparison.

A core framework and next-generation shell for tooling and automation at a command line level; with APIs for integration in IDEs, extending built in functionality with plugins, and scripting for automating repetitive tasks, Forge is a tool every open-source developer should be looking at. A core framework for rapid-application development in a standards-based environment. Plugins / incremental project enhancement for Java EE, and more.

If you've been tasked with the job of maintaining large and complex Hadoop clusters, or are about to be, this book is a must. You'll learn the particulars of Hadoop operations, from planning, installing, and configuring the system to providing ongoing maintenance.

"Rapture I/O is a fledgling library for Scala which provides a consistent, intuitive and extensible API for handling common I/O operations, such as sending HTTP requests and streaming data between files, URLs and sockets. Rapture I/O offers the functionality of java.io, but unifies its features into simpler, more coherent and higher-level concepts, allowing tasks which once took several lines of code to be often accomplished in just one, taking full advantage of Scala's rich syntax."

"Figaro is a probabilistic programming language that supports development of very rich probabilistic models and provides reasoning algorithms that can be applied to models to draw useful conclusions from evidence. Both model representation and reasoning algorithm development can be challenging tasks. Figaro makes it possible to express probabilistic models using the power of programming languages, giving the modeler the expressive tools to create a wide variety of models. Figaro comes with a number of built-in reasoning algorithms that can be applied automatically to new models. In addition, Figaro models are data structures in the Scala programming language, which is interoperable with Java, and can be constructed, manipulated, and used directly within any Scala or Java program."

"Fabric is a Python (2.5-2.7) library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks. It provides a basic suite of operations for executing local or remote shell commands (normally or via sudo) and uploading/downloading files, as well as auxiliary functionality such as prompting the running user for input, or aborting execution."

"Breaking distributed systems so you don't have to. Jepsen is a Clojure library. A test is a Clojure program which uses the Jepsen library to set up a distributed system, run a bunch of operations against that system, and verify that the history of those operations makes sense. Jepsen has been used to verify everything from eventually-consistent commutative databases to linearizable coordination systems to distributed task schedulers. It can also generate graphs of performance and availability, helping you characterize how a system responds to different faults. See jepsen.io for examples of the sorts of analyses you can carry out with Jepsen."
