bash Cookbook

Book Description

The key to mastering any Unix system, especially Linux and Mac OS X, is a thorough knowledge of shell scripting. Scripting is a way to harness and customize the power of any Unix system, and it’s an essential skill for any Unix users, including system administrators and professional OS X developers. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards.

bash Cookbook teaches shell scripting the way Unix masters practice the craft. It presents a variety of recipes and tricks for all levels of shell programmers so that anyone can become a proficient user of the most common Unix shell — the bash shell — and cygwin or other popular Unix emulation packages. Packed full of useful scripts, along with examples that explain how to create better scripts, this new cookbook gives professionals and power users everything they need to automate routine tasks and enable them to truly manage their systems — rather than have their systems manage them.

Mastering Algorithms with C

Posted: 15 Nov 2011 09:05 AM PST

Mastering Algorithms with C

Book Description

There are many books on data structures and algorithms, including some with useful libraries of C functions. Mastering Algorithms with C offers you a unique combination of theoretical background and working code. With robust solutions for everyday programming tasks, this book avoids the abstract style of most classic data structures and algorithms texts, but still provides all of the information you need to understand the purpose and use of common programming techniques.

Implementations, as well as interesting, real-world examples of each data structure and algorithm, are included.

Using both a programming style and a writing style that are exceptionally clean, Kyle Loudon shows you how to use such essential data structures as lists, stacks, queues, sets, trees, heaps, priority queues, and graphs. He explains how to use algorithms for sorting, searching, numerical analysis, data compression, data encryption, common graph problems, and computational geometry. And he describes the relative efficiency of all implementations. The compression and encryption chapters not only give you working code for reasonably efficient solutions, they offer explanations of concepts in an approachable manner for people who never have had the time or expertise to study them in depth.

Anyone with a basic understanding of the C language can use this book. In order to provide maintainable and extendible code, an extra level of abstraction (such as pointers to functions) is used in examples where appropriate. Understanding that these techniques may be unfamiliar to some programmers, Loudon explains them clearly in the introductory chapters.

Contents include:

  • Pointers
  • Recursion
  • Analysis of algorithms
  • Data structures (lists, stacks, queues, sets, hash tables, trees, heaps, priority queues, graphs)
  • Sorting and searching
  • Numerical methods
  • Data compression
  • Data encryption
  • Graph algorithms
  • Geometric algorithms

Practical C Programming, 3rd Edition

Posted: 15 Nov 2011 09:05 AM PST

Practical C Programming, 3rd Edition

Book Description

There are lots of introductory C books, but this is the first one that has the no-nonsense, practical approach that has made Nutshell Handbooks® famous.

C programming is more than just getting the syntax right. Style and debugging also play a tremendous part in creating programs that run well and are easy to maintain. This book teaches you not only the mechanics of programming, but also describes how to create programs that are easy to read, debug, and update.

Practical rules are stressed. For example, there are fifteen precedence rules in C (&& comes before || comes before ?:). The practical programmer reduces these to two:

  • Multiplication and division come before addition and subtraction.

Contrary to popular belief, most programmers do not spend most of their time creating code. Most of their time is spent modifying someone else’s code. This books shows you how to avoid the all-too-common obfuscated uses of C (and also to recognize these uses when you encounter them in existing programs) and thereby to leave code that the programmer responsible for maintenance does not have to struggle with. Electronic Archaeology, the art of going through someone else’s code, is described.

This third edition introduces popular Integrated Development Environments on Windows systems, as well as UNIX programming utilities, and features a large statistics-generating program to pull together the concepts and features in the language.

Data Mashups in R

Book Description

How do you use R to import, manage, visualize, and analyze real-world data? With this short, hands-on tutorial, you learn how to collect online data, massage it into a reasonable form, and work with it using R facilities to interact with web servers, parse HTML and XML, and more. Rather than use canned sample data, you’ll plot and analyze current home foreclosure auctions in Philadelphia.

This practical mashup exercise shows you how to access spatial data in several formats locally and over the Web to produce a map of home foreclosures. It’s an excellent way to explore how the R environment works with R packages and performs statistical analysis.

  • Parse messy data from public foreclosure auction postings
  • Plot the data using R’s PBSmapping package
  • Import US Census data to add context to foreclosure data

Parallel R

Book Description

It's tough to argue with R as a high-quality, cross-platform, open source statistical software product—unless you're in the business of crunching Big Data. This concise book introduces you to several strategies for using R to analyze large datasets. You'll learn the basics of Snow, Multicore, Parallel, and some Hadoop-related tools, including how to find them, how to use them, when they work well, and when they don't.

With these packages, you can overcome R's single-threaded nature by spreading work across multiple CPUs, or offloading work to multiple machines to address R's memory barrier.

  • Snow: works well in a traditional cluster environment
  • Multicore: popular for multiprocessor and multicore computers
  • Parallel: part of the upcoming R 2.14.0 release
  • R+Hadoop: provides low-level access to a popular form of cluster computing
  • RHIPE: uses Hadoop's power with R's language and interactive shell

Review
“…appropriate for those you’re trying to convince that Twitter is all the rage. The book reads like a beginner’s how-to guide, which means you could even use it as a subtle way to encourage less than stellar Twitter users to improve their Twittering ways.”
– Jennifer Van Grove, Mashable.com

“As easy to grasp as a tweet, this book cuts through the tiresome twitterhype and delivers a bunch of sensible, down-to-earth material on using and enjoying Twitter.”
– Cory Doctorow, co-editor of Boing Boing and author of Little Brother

“As with anything that gains high profile popularity there are plenty of Twitter haters out there, though the role that Twitter has played in the recent Iranian elections seems to have brought more legitimacy to Twitter in the eyes of many. With popularity come books and quite a few are already out there about and for twitter, but my favorite so far is The Twitter Book by Tim O’Reilly and Sarah Milstein.”
– JR Peck, Slashdot.org

“Ever been to Nepal? Me neither. However if I ever do go, even though the aborigines who live there are just like us, I will enlist a Sherpa to guide me through the landscape and the nuances of the culture. That’s what The Twitter Book is to Twitter. The Twitter community is, at its heart, filled with passionate people engaged in conversations. It’s just like Main Street USA. However, culturally, Twitter is its own country with its own language. Its various conventions like DMs and hashtags sound more like retro phrases from the 1960s than the underpinnings of one of the largest social networks on the web today. However, with a quick study, anyone can jump in, engage and accomplish their goals. With The Twitter Book, Sarah Milstein and Tim O’Reilly give you everything you need to get started while leaving just enough for readers to explore on their own. It’s an terrific resource I am recommending to all of our clients and anyone else who is curious about Twitter.”
– Steve Rubel, SVP/Director of Insights, Edelman Digital

“Once again, O’Reilly has put together a great, comprehensive primer. If you’re ready to dive into the world of Twitter, I highly recommend this book!”
– Tony Hsieh, CEO, Zappos

“Movie stars, media figures, captains of industry and book reviewers are doing it, but how can businesses discern the twits from the tweets? O’Reilly and Milstein present as lucid and intelligent an overview as you’d want or need. The format is concise but quite rich, and there’s plenty here to convince skeptics that employing Twitter as a marketing tool is a very good way to engage customers.”
– Richard Pachter, The Miami Herald

“The 234-page guide is so helpful that many readers no doubt will tweet its praises and thank ‘(at)timoreilly’ and ‘(at)sarahm’ – the authors’ Twitter handles – for helping people understand why Twitter is emerging as the Internet’s most powerful communications vehicle since e-mail.”
– Michael Liedtkeap, Associated Press

“Tim O’Reilly and Sarah Milstein are two of my favorite tweeters, and they’ve just written The Twitter Book, a pleasingly-designed 240-page guide to making the most out of Twitter.”
– Mark Frauenfelder, BoingBoing.net
