  • Testing To Prevent Cascading Bugs

    - by jfrankcarr
    Yesterday, Twitter was hit with a "Cascading Bug" as described in this blog post: A “cascading bug” is a bug with an effect that isn’t confined to a particular software element, but rather its effect “cascades” into other elements as well. I've seen this kind of bug, on a smaller scale of course, on some projects I've worked on. They can be difficult to identify in dev/test environments, even within a test driven development environment. My questions are... What are some strategies you use, beyond the basic TDD and standard regression testing, to identify and prevent the potential trouble points that might only occur in the production environment? Does the presence of such problems indicate a breakdown in the software development process or simply a by-product of complex software systems?

  • Can it be useful to build an application starting with the GUI?

    - by Grant Palin
    The trend in application design and development seems to be starting with the "guts": the domain, then data access, then infrastructure, etc. The GUI seems to usually come later in the process. I wonder if it could ever be useful to build the GUI first... My rationale is that by building at least a prototype GUI, you gain a better idea of what needs to happen behind the scenes, and so are in a better position to start work on the domain and supporting code. I can see an issue with this practice in that if the supporting code is not yet written, there won't be much for the GUI layer to actually do. Perhaps building mock objects or throwaway classes (somewhat like is done in unit testing) would provide just enough of a foundation to build the GUI on initially. Might this be a feasible idea for a real project? Maybe we could add GDD (GUI Driven Development) to the acronym stable...

  • Project Management Techniques (high level)

    - by Sam J
    Our software dev team is currently using kanban for our development lifecycles, and, from the reasonably short experience of a few months, I think it's going quite well (certainly compared to a few months ago when we didn't really have a methodology). Our team, however, is directed to do work defined by project managers (not software project managers, just general business), and they're using the PMBOK methodology. Question is, how does a traditional methodology like PMBOK, Prince2 etc fit with a lean software development methodology like kanban or scrum? Is it just wasting everyone's time as all the requirements are effectively drawn up to start with (although inevitably changed along the way)?

  • What is the career path for a software developer/ programmer? [closed]

    - by Lo Wai Lun
    I've been working as a programmer for a few months and I often study CCNA , CISSP for future. Besides simple coding I was working on specs, designing applications, and all those around-like things. My question is, I want to be a information / system security specialist. what's the career path I should be aiming for? Is it like working on code for the rest of my life? :) Restart my career from the network engineer ? Or do programmers make a good manager-position people ? I know it's very subjective. Thing is, lately I find myself much more into the designing/working on specs part of the development project then the coding itself. How do you see it? Would you like to go from development to information security? Would you like to work on a project with a manager that used to be a coder?

  • OpenJDK In The News: Oracle Outlines Roadmap for Java SE and JavaFX at JavaOne 2012

    - by $utils.escapeXML($entry.author)
    The OpenJDK Community continues to host the development of the reference implementation of Java SE 8. Weekly developer preview builds of JDK 8 continue to be available from jdk8.java.net.OpenJDK continues to thrive with contributions from Oracle, as well as other companies, researchers and individuals.The OpenJDK Web Site Terms of Use was recently updated to allow work on Java Specification Requests (JSRs) for Java SE to take place in the OpenJDK Community, alongside their corresponding reference implementations, so that specification leads can satisfy the new transparency requirements of the Java Community Process (JCP 2.8).“The recent decision by the Java SE 8 Expert Group to defer modularity to Java SE 9 will allow us to focus on the highly-anticipated Project Lambda, the Nashorn JavaScript engine, the new Date/Time API, and Type Annotations, along with numerous other performance, simplification, and usability enhancements,” said Georges Saab, vice president, Software Development, Java Platform Group at Oracle. “We are continuing to increase our communication and transparency by developing the reference implementation and the Oracle-led JSRs in the OpenJDK community.”Quotes taken from the 14th press release from Oracle mentioning OpenJDK, titled "Oracle Outlines Roadmap for Java SE and JavaFX at JavaOne 2012".
