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 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 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.
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.

Pragmatic Bookshelf
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 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.
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.

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 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 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 Bookshelf
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 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.
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 Bookshelf
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 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.
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.

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

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. don't use
any version control at all. Many others don't use it well, and end
up experiencing time-consuming problems.

title = Pragmatic Unit Testing (C#)
description = <p>
Pragmatic programmers use feedback to drive their development and
personal processes. The most valuable feedback you can get while
coding comes from unit testing.
</p>
<p>
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 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 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.
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.
