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.

Distributed Configuration Management: Mercurial CSCI 5828 Spring 2012 Mark Grebe Configuration Management
Distributed Configuration Management: Mercurial CSCI 5828 Spring 2012 Mark Grebe Configuration Management Configuration Management (CM) systems are used to store code and other artifacts in Software Engineering projects. Since the early 70’s, there has been a progression of CM systems used for Software CM, starting with SCCS, and continuing through RCS, CVS, and Subversion. All of these systems used a single, centralized repository structure. Distributed Configuration Management As opposed to traditional CM systems, Distributed Configuration Management Systems are ones where there does not have to be a central repository. Each developer has a copy of the entire repository and history. A central repository may be optionally used, but it is equal to all of the other developer repositories. Advantages of Distributed Configuration Management Distributed tools are faster than centralized ones since metadata is stored locally. Can use tool to manage changes locally while not connected to the network where server resides. Scales more easily, since all of the load is not on a central server. Allows private work that is controlled, but not released to the larger community. Distributed systems are normally designed to make merges easy, since they are done more often. Mercurial Introduction Mercurial is a cross-platform, distributed configuration management application. In runs on most modern OS platforms, including Windows, Linux, Solaris, FreeBSD, and Mac OSX. Mercurial is written 95% in Python, with the remainder written in C for speed. Mercurial is available as a command line tool on all of the platforms, and with GUI support programs on many of the platforms. Mercurial is customizable with extensions, hooks, and output templates. -

Homework 0: Account Setup for Course and Cloud FPGA Intro Questions
Cloud FPGA Homework 0 Fall 2019 Homework 0 Jakub Szefer 2019/10/20 Please follow the three setup sections to create BitBucket git repository, install LATEX tools or setup Overleaf account, and get access to the course's git repository. Once you have these done, answer the questions that follow. Submit your solutions as a single PDF file generated from a template; more information is at end in the Submission Instructions section. Setup BitBucket git Repository This course will use git repositories for code development. Each student should setup a free BitBucket (https://bitbucket.org) account and create a git repository for the course. Please make the repository private and give WRITE access to your instructor ([email protected]). Please send the URL address of the repository to the instructor by e-mail. Make sure there is a README:md file in the repository (access to the repository will be tested by a script that tries to download the README:md from the repository address you share). Also, if you are using a Apple computer, please add :gitignore file which contains one line: :DS Store (to prevent the hidden :DS Store files from accidentally being added to the repository). If you have problems accessing BitBucket git from the command line, please see the Appendix. Setup LATEX and Overleaf Any written work (including this homework's solutions) will be submitted as PDF files generated using LATEX [1] from provided templates. Students can setup a free Overleaf (https://www. overleaf.com) account to edit LATEX files and generate PDFs online; or students can install LATEX tools on their computer. -

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, -
