Pragmatic Version Control Using Subversion
What readers are saying about Pragmatic Version Control using Subversion I expected a lot, but you surprised me with even more. Hav- ing used CVS for years I hesitated to try Subversion until now, although I knew it would solve many of the shortcom- ings of CVS. After reading your book, my excuses to stay with CVS disappeared. Oh, and coming from the Pragmatic Bookshelf this book is fun to read too. Thanks Mike. Steffen Gemkow Managing Director, ObjectFab GmbH I’m a long-time user of CVS and I’ve been skeptical of Sub- version, wondering if it would ever be “ready for prime time.” Until now. Thanks to Mike Mason for writing a clear, con- cise, gentle introduction to this new tool. After reading this book, I’m actually excited about the possibilities for version control that Subversion brings to the table. David Rupp Senior Software Engineer, Great-West Life & Annuity This was exactly the Subversion book I was waiting for. As a long-time Perforce and CVS user and administrator, and in my role as an agile tools coach, I wanted a compact book that told me just what I needed to know. This is it. Within a couple of hours I was up and running against remote Subversion servers, and setting up my own local servers too. Mike uses a lot of command-line examples to guide the reader, and as a Windows user I was worried at first. My fears were unfounded though—Mike’s examples were so clear that I think I’ll stick to using the command line from now on! I thoroughly recommend this book to anyone getting started using or administering Subversion. -

Version Control 101 Exported from http://cepsltb4.curent.utk.edu/wiki/efficiency/vcs, please visit the link for the latest version and the best typesetting. Version Control 101 is created in the hope to minimize the regret from lost files or untracked changes. There are two things I regret. I should have learned Python instead of MATLAB, and I should have learned version control earlier. Version control is like a time machine. It allows you to go back in time and find out history files. You might have heard of GitHub and Git and probably how steep the learning curve is. Version control is not just Git. Dropbox can do version control as well, for a limited time. This tutorial will get you started with some version control concepts from Dropbox to Git for your needs. More importantly, some general rules are suggested to minimize the chance of file losses.

Version Control – Agile Workflow with Git/Github
Version Control – Agile Workflow with Git/GitHub 19/20 November 2019 | Guido Trensch (JSC, SimLab Neuroscience) Content Motivation Version Control Systems (VCS) Understanding Git GitHub (Agile Workflow) References Forschungszentrum Jülich, JSC:SimLab Neuroscience 2 Content Motivation Version Control Systems (VCS) Understanding Git GitHub (Agile Workflow) References Forschungszentrum Jülich, JSC:SimLab Neuroscience 3 Motivation • Version control is one aspect of configuration management (CM). The main CM processes are concerned with: • System building • Preparing software for releases and keeping track of system versions. • Change management • Keeping track of requests for changes, working out the costs and impact. • Release management • Preparing software for releases and keeping track of system versions. • Version control • Keep track of different versions of software components and allow independent development. [Ian Sommerville,“Software Engineering”] Forschungszentrum Jülich, JSC:SimLab Neuroscience 4 Motivation • Keep track of different versions of software components • Identify, store, organize and control revisions and access to it • Essential for the organization of multi-developer projects is independent development • Ensure that changes made by different developers do not interfere with each other • Provide strategies to solve conflicts CONFLICT Alice Bob Forschungszentrum Jülich, JSC:SimLab Neuroscience 5 Content Motivation Version Control Systems (VCS) Understanding Git GitHub (Agile Workflow) References Forschungszentrum Jülich, -

Scaling Git with Bitbucket Data Center
Scaling Git with Bitbucket Data Center Considerations for large teams switching to Git Contents What is Git, why do I want it, and why is it hard to scale? 01 Scaling Git with Bitbucket Data Center 05 What about compliance? 11 Why choose Bitbucket Data Center? 13 01 What is Git, why do I want it, and why is it hard to scale? So. Your software team is expanding and taking on more high-value projects. That’s great news! The bad news, however, is that your centralized version control system isn’t really cutting it anymore. For growing IT organizations, Some of the key benefits Codebase safety moving to a distributed version control system is now of adopting Git are: Git is designed with maintaining the integrity considered an inevitable shift. This paper outlines some of managed source code as a top priority, using secure algorithms to preserve your code, change of the benefits of Git as a distributed version control system history, and traceability against both accidental and how Bitbucket Data Center can help your company scale and malicious change. Distributed development its Git-powered operations smoothly. Community Distributed development gives each developer a working copy of the full repository history, Git has become the expected version control making development faster by speeding up systems in many circles, and is very popular As software development increases in complexity, and the commit process and reducing developers’ among open source projects. This means its easy development teams become more globalized, centralized interdependence, as well as their dependence to take advantage of third party libraries and on a network connection. -

Branching Strategies with Distributed Version Control in Agile Projects
Branching Strategies with Distributed Version Control in Agile Projects David Arve March 2, 2010 Abstract Branching strategies play an integral part in traditional software de- velopment. In Agile projects however branching is seen as the opposite to embracing change and therefor given little attention. This paper describes what branching strategies would support an agile workflow. It also describes how a distributed version control tool will fit better around these branching strategies then a centralized tool. This pa- per puts forth some original work on what branching strategies and team organization that fully takes advantage of a distributed version control tool. This paper aims to describe how a distributed version control can support agile teams with advanced branching strategies without slowing down or complicating the lightweight agile processes. 1 Introduction Software development is a process that produces a massive amount of highly complicated content. All of this content is produced by teams that range from just a few developers up to several thousands. It is obvious that this process needs to be highly coordinated. The coordination of this content is a part of Software configuration management (SCM). Traditionally this has been done by a centralized version control tool. [2] Branching strategies have not gained a lot of popularity in agile teams. [3] In recent years several new version control tools have emerged. These new tools break with the standard model of centralized version control (CVC) made popular by tools like CVS [9] and Subversion[6]. The new tools are based on a distributed model. Recent tools include Arch [5], Bazaar [8], BitKeeper [7] and Git [11]. -
