Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

organization := "com.packt"

name := "chapter1-breeze"

scalaVersion := "2.10.4"

libraryDependencies  ++= Seq(
  "org.scalanlp" %% "breeze" % "0.11.2",
  //Optional - the 'why' is explained in the How it works section
  "org.scalanlp" %% "breeze-natives" % "0.11.2"
)

Any command-line input or output is written as follows:

sudo apt-get install libatlas3-base libopenblas-base
sudo update-alternatives --config libblas.so.3
sudo update-alternatives --config liblapack.so.3

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Now, if we wish to share this chart with someone or link it to an external website, we can do so by clicking on the gear icon in this paragraph and then clicking on Link this paragraph."
