Contents ● Goal of Open Source Jumpstart series ● Open source software (OSS) overview ● Common development environment ● OSS tools overview ● How OSS tools support agile practices ● Eclipse ”live” demo ©LeanAgileMachine Creative Commons License

Goals of OS Jumpstart ● Bridge the gap between academia and industry ● Introduce open source software (OSS) concept ● Highlight significance of OSS ● Show how OSS tools support the agile process ● Introduce the commonly used OSS tools in industry for development and testing ©LeanAgileMachine Creative Commons License

The Modern Developer ● The role of a developer has changed radically ● They need to be extremely flexible ● They work on increasingly complex systems ● Requirements change at the drop of a hat ©LeanAgileMachine Creative Commons License

Gap between study and industry ● University can only teach you so much ● Good placements help but are not easy to find ● Build on what you know ● Learn what happens in industry ● Build your skill set beyond your peers ● Experience practical application of skills on projects ● Make you CV more interesting to employers ● Increase your earning potential ©LeanAgileMachine Creative Commons License

Do you use OSS ? Raise your hand if you already use OSS ? ©LeanAgileMachine Creative Commons License

Some popular OSS examples ©LeanAgileMachine Creative Commons License

What is Open Source ● A licence model to distribute software ● http://en.wikipedia.org/wiki/Comparison_of_free_software_licenses ● Openness and freedom within software ● A open, collaborative and agile approach to development ● A move away from low value commercial and/or restrictive software ©LeanAgileMachine Creative Commons License

Why use Open Source ?? ● Its freely available – download it and try it out ● You can see how it works under the hood ● You can improve / extend how it works ● Communities to help you get things done ● OSS tools very common in industry ● Used extensively in agile companies ● Latest technology often OSS ● Scala, Clojure, BDD tools, NoSQL, etc ©LeanAgileMachine Creative Commons License

Is it really free? ● Copyright still applies ● Licence included in source code distribution ● Variety of licences ● GPL / LGPL – require giving back ● Apache License – commercial friendly ● Creative Commons – other creative works ● Community help given freely ● Commercial support available for big projects ©LeanAgileMachine Creative Commons License

My company will provide... ● Companies tend not to give you everything ● Fill in the gaps with OSS ● Cost savings on commondity things mean more spending on high value stuff / training ● Many commercial products use OSS ● IBM, Microsoft, Oracle, Google, ©LeanAgileMachine Creative Commons License

So what's out there in OSS land? ● Operating Systems ● Android, Ubuntu, Debian, Fedora, SuSe, etc ● Productivity suites ● Open Office, Inkscape, Gimp, OpenShot, Audacity, blender, etc... ● Development languages ● Java, Scala, Clojure, C, C++, Python, Perl, PhP, etc ● Development and testing tools... ©LeanAgileMachine Creative Commons License

OSS development and testing tools ©LeanAgileMachine Creative Commons License

A Basic Development Environment ©LeanAgileMachine Creative Commons License

End to end Development & Test Environment ● Build Management ● Development ● Version control ● IDE / Editor ● Build managment ● Unit testing ● Continuous Integration ● Acceptance testing ● Deployment ● Issue / bug tracking ● Application testing ● Collaborative / Cloud ● Functional workspaces ● Load / Performance ©LeanAgileMachine Creative Commons License

Version Control ● Version all changes to the code ● Snapshots of known code state CVS ● Identify release code bases Subversion ● Gives audit trail of changes Git ● Experiment with code in branches ● Rollback to a known state in code Mercurial ● Collective ownership of code ● Access open source project code ©LeanAgileMachine Creative Commons License

Build Tools ● Build Automation ● Compile, test and deploy code Ant.apache.org with simple commands ● Consistent build tasks ant.apache.org/ivy ● Manage dependant activties Maven.apache.org ● eg. run tests when compiling ● Library dependancy Comparison of tools: management http://ant.apache.org/ivy/ m2comparison.html ● Call external tools / apps ©LeanAgileMachine Creative Commons License

Integrated Development Environments ● Manage large / multiple projects ● Debugger ● Autocompletion (code api completion) ● Refactoring .org ● Build management Ant / Maven – compile, test, deploy .org ● ● Integration ● Application servers, databases, unit testing, Scm, bug tracker, CI server, IntelliJ IDEA jetbrains.org ©LeanAgileMachine Creative Commons License

Unit Testing ● Unit testing foremost a design process ● Identify responsibilities and behavior ● Define success at class level ● Test framework for your Java classes ● Tests and test suites ● Supports test driven development (TDD) ● Write a failing test, write code to make it pass ● Run tests when compiling ● Contiually check code changes ● Reduce bugs entering the code base ©LeanAgileMachine Creative Commons License

Acceptance Testing ● Extends Test Driven Development ● Greater user focus ● Looser coupled testing Fitnesse.org ● Using the language of the business ● Thinking about the user interaction ● Knowing when you are done! ● Behaviour driven development Cuke4Duke EasyB ● a Lean thinking approach ©LeanAgileMachine Creative Commons License

BDD Feature Example ©LeanAgileMachine Creative Commons License

Continuous Integration ● Regularly runs unit / acceptance tests, compile code, integration scripts, application tests, etc ● Triggered at intervals or on source code commits ● Builds all or part of code base ● Helps with regular releases / agile practices Hudsonci.org ● Know if your build will work for your showcase ● Early and continual feedback system ● Identifys chages that breaks the build ● Often used with large display / Lava lamp Continuum ● Code metrics and project health reports ©LeanAgileMachine Creative Commons License

Issue / Bug Tracking ● Manage workload backlog ● Features, stories, etc Bugzilla ● Manage bugs Jira ● Linked to scm code checkin ● Show progress to nontechnical stakeholders ● Extend with Scrum or Kanban board approach ©LeanAgileMachine Creative Commons License

Collaborative workspace ● Capture important knowledge and communication Mediawiki ● Limit need for overbearing docs Liferay ● Discussion boards ● Wiki pages ● Coding standard documents ● Discuss issues ● Useful for disparate teams ©LeanAgileMachine Creative Commons License

Summary of OSS tools ● End to end tool support ● Helps your carrer ● Tools incorporated into prospects modern ide's ● Work on OSS ● Tools can be used to give projects continuous feedback on your progress ● Access to new technology and ● Help you become more techniques agile ©LeanAgileMachine Creative Commons License

Eclipse Live Demo Version control demo using Subversion, Eclipse and the Subclipse plugin by Ben Evans ©LeanAgileMachine Creative Commons License

Jumpstart Summary ● OSS tools help create ● Lots more to learn an agile environment about each tool ● OSS tools are widely ● Follow up sessions used in industry discuss each tool ● Knowing these kind of area in detail tools help you get ● Lots of tutorials and interesting jobs books to help ©LeanAgileMachine Creative Commons License

LJC Unconference 2 ● Saturday 26th June 2010 – 9.30am ● Great opportunity to hear from people in industry ● Find out more about OSS tools, new things in Java, Functional programming, agile practices, acceptance testing and lots lots more... ● Discuss your ideas and problems ● Practice your presentation skills by giving a talk ● Gain confidence for presenting to a team / manager ● Register at London Java Community Meetup site ● Book online at SkillsMatter.com ©LeanAgileMachine Creative Commons License
