Title: Pragmatic Version Control

Description: <p> This book is a recipe-based approach to using Subversion that will get you up and running quickly---and correctly. All projects need version control: it's a foundational piece of any project's infrastructure. Yet half of all project teams in the U.S. dont use any version control at all. Many others dont use it well, and end up experiencing time-consuming problems. </p>

Pragmatic Project Automation

Pragmatic Project Automation shows you how to improve the consistency and repeatability of your project's procedures using automation to reduce risk and errors.

Simply put, we're going to put this thing called a computer to work for you doing the mundane (but important) project stuff. That means you'll have more time and energy to do the really exciting---and difficult---stuff, like writing quality code.

Pragmatic Unit Testing (C#)

Pragmatic programmers use feedback to drive their development and personal processes. The most valuable feedback you can get while coding comes from unit testing.

Without good tests in place, coding can become a frustrating game of "whack-a-mole." That's the carnival game where the player strikes at a mechanical mole; it retreats and another mole pops up on the opposite side of the field. The moles pop up and down so fast that you end up flailing your mallet helplessly as the moles continue to pop up where you least expect them.

Pragmatic Version Control

This book is a recipe-based approach to using Subversion that will get you up and running quickly---and correctly. All projects need version control: it's a foundational piece of any project's infrastructure. Yet half of all project teams in the U.S. don't use any version control at all. Many others don't use it well, and end up experiencing time-consuming problems.

Pragmatic Project Automation

Pragmatic Project Automation shows you how to improve the consistency and repeatability of your project's procedures using automation to reduce risk and errors.

Simply put, we're going to put this thing called a computer to work for you doing the mundane (but important) project stuff. That means you'll have more time and energy to do the really exciting---and difficult---stuff, like writing quality code.

Pragmatic Unit Testing (C#)

Pragmatic programmers use feedback to drive their development and personal processes. The most valuable feedback you can get while coding comes from unit testing.

Without good tests in place, coding can become a frustrating game of "whack-a-mole." That's the carnival game where the player strikes at a mechanical mole; it retreats and another mole pops up on the opposite side of the field. The moles pop up and down so fast that you end up flailing your mallet helplessly as the moles continue to pop up where you least expect them.

Pragmatic Version Control

This book is a recipe-based approach to using Subversion that will get you up and running quickly---and correctly. All projects need version control: it's a foundational piece of any project's infrastructure. Yet half of all project teams in the U.S. don't use any version control at all. Many others don't use it well, and end up experiencing time-consuming problems.

Pragmatic Project Automation

Pragmatic Project Automation shows you how to improve the consistency and repeatability of your project's procedures using automation to reduce risk and errors.

Simply put, we're going to put this thing called a computer to work for you doing the mundane (but important) project stuff. That means you'll have more time and energy to do the really exciting---and difficult---stuff, like writing quality code.

Pragmatic Unit Testing (C#)

Pragmatic programmers use feedback to drive their development and personal processes. The most valuable feedback you can get while coding comes from unit testing.

Without good tests in place, coding can become a frustrating game of "whack-a-mole." That's the carnival game where the player strikes at a mechanical mole; it retreats and another mole pops up on the opposite side of the field. The moles pop up and down so fast that you end up flailing your mallet helplessly as the moles continue to pop up where you least expect them.

Pragmatic Version Control

This book is a recipe-based approach to using Subversion that will get you up and running quickly---and correctly. All projects need version control: it's a foundational piece of any project's infrastructure. Yet half of all project teams in the U.S. don't use any version control at all. Many others don't use it well, and end up experiencing time-consuming problems.

Pragmatic Project Automation

Pragmatic Project Automation shows you how to improve the consistency and repeatability of your project's procedures using automation to reduce risk and errors.

Simply put, we're going to put this thing called a computer to work for you doing the mundane (but important) project stuff. That means you'll have more time and energy to do the really exciting---and difficult---stuff, like writing quality code.

Pragmatic Unit Testing (C#)

Pragmatic programmers use feedback to drive their development and personal processes. The most valuable feedback you can get while coding comes from unit testing.

Without good tests in place, coding can become a frustrating game of "whack-a-mole." That's the carnival game where the player strikes at a mechanical mole; it retreats and another mole pops up on the opposite side of the field. The moles pop up and down so fast that you end up flailing your mallet helplessly as the moles continue to pop up where you least expect them.

Pragmatic Version Control

This book is a recipe-based approach to using Subversion that will get you up and running quickly---and correctly. All projects need version control: it's a foundational piece of any project's infrastructure. Yet half of all project teams in the U.S. don't use any version control at all. Many others don't use it well, and end up experiencing time-consuming problems.

Pragmatic Project Automation

    

       Pragmatic Project Automation shows you how to improve the 
       consistency and repeatability of your project's procedures using 
       automation to reduce risk and errors.
      

      

        Simply put, we're going to put this thing called a computer to work 
        for you doing the mundane (but important) project stuff. That means 
        you'll have more time and energy to do the really 
        exciting---and difficult---stuff, like writing quality code.

Pragmatic Unit Testing (C#)

    

        Pragmatic programmers use feedback to drive their development and 
        personal processes. The most valuable feedback you can get while 
        coding comes from unit testing.
      

      

        Without good tests in place, coding can become a frustrating game of 
        "whack-a-mole." That's the carnival game where the player strikes at a 
        mechanical mole; it retreats and another mole pops up on the opposite side 
        of the field. The moles pop up and down so fast that you end up flailing 
        your mallet helplessly as the moles continue to pop up where you least 
        expect them.

Pragmatic Project Automation

    

       Pragmatic Project Automation shows you how to improve the 
       consistency and repeatability of your project's procedures using 
       automation to reduce risk and errors.
      

      

        Simply put, we're going to put this thing called a computer to work 
        for you doing the mundane (but important) project stuff. That means 
        you'll have more time and energy to do the really 
        exciting---and difficult---stuff, like writing quality code.

Pragmatic Unit Testing (C#)

    

        Pragmatic programmers use feedback to drive their development and 
        personal processes. The most valuable feedback you can get while 
        coding comes from unit testing.
      

      

        Without good tests in place, coding can become a frustrating game of 
        "whack-a-mole." That's the carnival game where the player strikes at a 
        mechanical mole; it retreats and another mole pops up on the opposite side 
        of the field. The moles pop up and down so fast that you end up flailing 
        your mallet helplessly as the moles continue to pop up where you least 
        expect them.

Pragmatic Version Control

    

         This book is a recipe-based approach to using Subversion that will 
         get you up and running quickly---and correctly. All projects need
         version control: it's a foundational piece of any project's 
         infrastructure. Yet half of all project teams in the U.S. don't use
         any version control at all. Many others don't use it well, and end 
         up experiencing time-consuming problems.

Pragmatic Project Automation

    

       Pragmatic Project Automation shows you how to improve the 
       consistency and repeatability of your project's procedures using 
       automation to reduce risk and errors.
      

      

        Simply put, we're going to put this thing called a computer to work 
        for you doing the mundane (but important) project stuff. That means 
        you'll have more time and energy to do the really 
        exciting---and difficult---stuff, like writing quality code.

Pragmatic Unit Testing (C#)

    

        Pragmatic programmers use feedback to drive their development and 
        personal processes. The most valuable feedback you can get while 
        coding comes from unit testing.
      

      

        Without good tests in place, coding can become a frustrating game of 
        "whack-a-mole." That's the carnival game where the player strikes at a 
        mechanical mole; it retreats and another mole pops up on the opposite side 
        of the field. The moles pop up and down so fast that you end up flailing 
        your mallet helplessly as the moles continue to pop up where you least 
        expect them.

Pragmatic Version Control

    

         This book is a recipe-based approach to using Subversion that will 
         get you up and running quickly---and correctly. All projects need
         version control: it's a foundational piece of any project's 
         infrastructure. Yet half of all project teams in the U.S. don't use
         any version control at all. Many others don't use it well, and end 
         up experiencing time-consuming problems.

Greetings from RDoc



Let’s see if we’re doing real formatting…



    

    

    
get /test/date_format

time_ago_in_words(Time.utc(2004, 12, 25)) => about 5 years

    

    
get /test/example1

    

      
Time.now => Tue Feb 02 14:36:22 -0500 2010

      
request.path => /test/example1

      
a = 1 => 1

      
b = 2 => 2

Pragmatic Project Automation

    

       Pragmatic Project Automation shows you how to improve the 
       consistency and repeatability of your project's procedures using 
       automation to reduce risk and errors.
      

      

        Simply put, we're going to put this thing called a computer to work 
        for you doing the mundane (but important) project stuff. That means 
        you'll have more time and energy to do the really 
        exciting---and difficult---stuff, like writing quality code.

Pragmatic Unit Testing (C#)

    

        Pragmatic programmers use feedback to drive their development and 
        personal processes. The most valuable feedback you can get while 
        coding comes from unit testing.
      

      

        Without good tests in place, coding can become a frustrating game of 
        "whack-a-mole." That's the carnival game where the player strikes at a 
        mechanical mole; it retreats and another mole pops up on the opposite side 
        of the field. The moles pop up and down so fast that you end up flailing 
        your mallet helplessly as the moles continue to pop up where you least 
        expect them.

Pragmatic Version Control

    

         This book is a recipe-based approach to using Subversion that will 
         get you up and running quickly---and correctly. All projects need
         version control: it's a foundational piece of any project's 
         infrastructure. Yet half of all project teams in the U.S. don't use
         any version control at all. Many others don't use it well, and end 
         up experiencing time-consuming problems.
