Airflow Documentation
Airflow is a platform to programmatically author, schedule and monitor workflows. Use airflow to author workflows as directed acyclic graphs DAGs) of tasks. The airflow scheduler executes your tasks on an array of workers while following the specified dependencies. Rich command line utilities make performing.
complex surgeries on DAGs a snap. The rich user interface makes it easy to visualize pipelines running in production,
monitor progress, and troubleshoot issues when needed.

An.Introduction.to.Machine.Learning.with.Application.in.R
The purpose of this document is to provide a conceptual introduction
to statistical or machine learning (ML) techniques for those that might
not normally be exposed to such approaches during their required
typical statistical training 1 . Machine learning 2 can be described as
a form of a statistics, often even utilizing well-known nad familiar
techniques, that has bit of a different focus than traditional analytical
practice in the social sciences and other disciplines. The key notion is
that flexible, automatic approaches are used to detect patterns within
the data, with a primary focus on making predictions on future data.

R Graphics
This practical guide provides more than 150 recipes to help you generate high-quality graphs quickly, without having to comb through all the details of R's graphing systems. Each recipe tackles a specific problem with a solution you can apply to your own project, and includes a discussion of how and why the recipe works. Most of the recipes use the ggplot2 package, a powerful and flexible way to make graphs in R. If you have a basic understanding of the R language, you're ready to get started.

Visualize This
This book is example-driven and written to give you the skills to take a
graphic from start to finish. You can read it cover to cover, or you can pick
your spots if you already have a dataset or visualization in mind. The chap-
ters are organized so that the examples are self-contained. If you’re new
to data, the early chapters should be especially useful to you. They cover
how to approach your data, what you should look for, and the tools avail-
able to you. You can see where to find data and how to format and prepare
it for visualization. After that, the visualization techniques are split by data
type and what type of story you’re looking for.

编码的奥秘
渴望交流是大多数人的天性。在本书中，“编码”通常指一种在人和机器之间进行信息转换的系统。换句话说、编码即是交流。有时我们将编码看得很神秘，其实大多数编码并非都是这样。大多数的编码都需要被很好地理解，因为它们是人类交流的基础。
在本书中，作者Charles Petzold用常见的对象和诸如布莱叶盲文、摩尔斯电码之类大家熟悉的语言系统，为那些曾经想知道计算机和其他智能机器内部“生命”奥秘的人们编排了一个生动的叙述。
本书由灵活的图解和生动的故事组成。沿着作者的这种介绍思路，通过本书的学习你将会发现你已经获得了一个理解今天的PC、数字多媒体和因特网的真实背景。无论你的技术水平怎样，本书都将会使你陶醉，并且很可能唤醒读者参与计算机事业。

Stream Data Processing A Quality of Service Perspective
The systems used to process data streams and provide for the needs of stream-based applications are Data Stream Management Systems (DSMSs). This book presents a new paradigm to meet the needs of these applications, including a detailed discussion of the techniques proposed. Ii includes important aspects of a QoS-driven DSMS (Data Stream Management System) and introduces applications where a DSMS can be used and discusses needs beyond the stream processing model. It also discusses in detail the design and implementation of MavStream. This volume is primarily intended as a reference book for researchers and advanced-level students in computer science. It is also appropriate for practitioners in industry who are interested in developing applications.

Professional NoSQL
A hands-on guide to leveraging NoSQL databases NoSQL databases are an efficient and powerful tool for storing and manipulating vast quantities of data. Most NoSQL databases scale well as data grows. In addition, they are often malleable and flexible enough to accommodate semi-structured and sparse data sets. This comprehensive hands-on guide presents fundamental concepts and practical solutions for getting you ready to use NoSQL databases.

CouchDB.The.Definitive.Guide
This book introduces you to Apache CouchDB, a document-oriented database that offers a different way to model your data. CouchDB is a schema-free database, designed to work with applications that handle document-based information such as contacts, invoices, and receipts. In "CouchDB: The Definitive Guide", three of the core developers gently explain how to work with CouchDB, using clear and practical scenarios. Each chapter showcases key features, such as simple document CRUD (create, read, updated, delete), advanced MapReduce, and deployment tuning for performance and reliability. With this book, you will: understand the basics of document-based storage and manipulation; model data as self-contained JSON documents; manage basic document CRUD; handle evolving data naturally; query and aggregate data in CouchDB, using MapReduce views; replicate data between nodes; and, carry out deployment tuning for performance and reliability.

MapReduce架构
MapReduce 是一个编程模型,也是一个处理和生成超大数据集的算法模型的相关实现。用户首先创建一个 Map 函数处理一个基于 key/value pair 的数据集合,
输出中间的基于 key/value pair 的数据集合;然后再创建一个 Reduce 函数用来
合并所有的具有相同中间 key 值的中间 value 值。现实世界中有很多满足上述处理模型的例子, 本论文将详细描述这个模型。

building query compilers
The book tries to demystify query optimization and query optimizers. By
means of the multi-lingual query optimizer BD II, the most important aspects
of query optimizers and their implementation are discussed. We concentrate
not only on the query optimizer core (Rewrite I, Plan Generator, Rewrite II)
of the query compilation process but touch on all issues from parsing to code
generation and quality assurance.

Principles of Distributed Database Systems
The material concentrates on fundamental theories as well as techniques and algorithms. The advent of the Internet and the World Wide Web, and, more recently, the emergence of cloud computing and streaming data applications, has forced a renewal of interest in distributed and parallel data management, while, at the same time, requiring a rethinking of some of the traditional techniques.
