  • How to write constructors which might fail to properly instantiate an object

    - by whitman
    Sometimes you need to write a constructor which can fail. For instance, say I want to instantiate an object with a file path, something like obj = new Object("/home/user/foo_file") As long as the path points to an appropriate file everything's fine. But if the string is not a valid path things should break. But how? You could: 1. throw an exception 2. return null object (if your programming language allows constructors to return values) 3. return a valid object but with a flag indicating that its path wasn't set properly (ugh) 4. others? I assume that the "best practices" of various programming languages would implement this differently. For instance I think ObjC prefers (2). But (2) would be impossible to implement in C++ where constructors must have void as a return type. In that case I take it that (1) is used. In your programming language of choice can you show how you'd handle this problem and explain why?

  • SOA Forcing A Shift In IT Governance

    As more and more companies adopt a service oriented approach to developing and maintaining existing enterprise systems, IT governance also needs to shift its philosophies to fit the emerging development paradigm. When I first started programming companies placed an emphasis on “Code and Go” software development style. They only developed for current problems and did not really take a look at how the company could leverage some of the code we were developing across the entire enterprise system.  The concept of Service Oriented Architecture (SOA) has dramatically shifted how we develop enterprise software with emphasizing software processes as company assets. This has driven some to start developing new components as processes strictly for the possibility of future integration of existing and new systems. I personally like this new paradigm because it truly promotes code reusability. However, most enterprise level IT governance polices were created prior to the introduction of SOA in their respected organization. This can create a sense of the Wild West for developers working on projects related to SOA. This is due to the fact that a lot of the standards and polices implemented by enterprise IT governing boards were initially for developing under the “Code and Go” paradigm and do not take in to account idiosyncrasies found in the SOA/integration based development. As IT governance moves forward its focus should aim more for “Develop to Integrate” versus “Code and Go” philosophies. Examples of “Develop to Integrate” Philosophy: Defining preferred data transfer methodologies (XML vs. JSON), and when to use them Updating security best practices for exposing public services based on existing standard security policies Define when to use create new SOA project vs. implementing localized components that could be reused elsewhere in the enterprise.

  • The most mind-bending programming language?

    - by Xepoch
    From a reasonably common programming language, which do you find to be the most mind-bending? I have been listening to a lot of programming podcasts and taking some time to learn some new languages that are being considered upcoming, and important. I'm not necessarily talking about BrainFuck, but which language would you consider to be one that challenges the common programming paradigms? For me, I did some functional and logic (ex. Prolog) programming in the 90s, so can't say that I find anything special there. I am far from being an expert in it, but even today the most mind-bending programming language for me is Perl. Not because "Hello World" is hard to implement but rather there is so much lexical flexibility that some of the hardest solutions can be decomposed so poetically that I have to walk outside away from my terminal to clear my head. I'm not saying I'd likely sell a commercial software implementation, just that there is a distinct reason Perl is so (in)famous. Just look at the basic list of books on it. So, what is your mind-bending language that promotes your better programming and practices?

    Chrome Mobile Monthly: Responsive vs Separate Sites Join us on Wednesday October 31st at 9am PT for our Monthly Mobile Web Hangout! This month +Brad Frost will be joining us to talk about responsive design versus separate mobile sites. And in keeping with the season, it's a special Presidential Smackdown Edition. The US presidential race is in full swing, and the candidates are intensely debating the country's hot-button issues. The web design world is entrenched in our own debate about how to address the mobile web: should we create a separate mobile site or create a responsive experience instead? It just so happens that the two US presidential candidates have chosen different mobile web strategies for their official websites. In the red corner is Republican candidate Mitt Romney's dedicated mobile site, while in the blue corner is incumbent president Barack Obama's responsive website. Which will prevail? Sit back, crack open a cold one, and watch the battle unfold as Brad dissect the candidates' sites to uncover best practices and common mobile web pitfalls.

  • Software vs Network Engineer (Salary, Difficulty, Learning, Happiness)

    - by B Z
    What are your thoughts on being a Software Engineer vs a Network Engineer? I've been on the software field for almost 10 years now and although I still have a great deal of fun (and challenges), I am starting to think it could be better on the "other" side. Not to degrade network engineers (i know there are many great ones out there), it seems (in general) their job is easier, the learning curve from average to good is not as steep, job is less stressful and pay is better on average. I think as software developer I could make the switch to networking and still enjoy working with computers and feel productive. I spend an enormous amount of time learning about software, practices, new technologies, new patters, etc...I think I could spend a much smaller amount of time learning about networking and be just as "good". What are your thoughts? EDIT: This is not about making easy money. Networking and Software are closely related, I love computers and programming, but if I can work with both, make more money and have less stress in my life and can spend more time with my family, then I am willing to consider a change and hence I am looking for advice that Do or Don't support this view.

  • Software development process for a part time University project for 1 developer?

    - by Pricey
    I will be doing a part time University project soon and the time frame for it is around 8 months with approximately 10-15 hours a week spent working on it, with a review by a tutor each quarter. My question is what software development process would you recommend using when the course requires you to work on your own in order to manage yourself as well as the project? I wanted to use a weekly or bi-weekly iterative approach to my work but a lot of the processes seem tailored to teams of people. I am looking at XP (Extreme Programming) OR Scrum as something that is less than the norm for University work but again Scrum I don't know a lot about yet, and a question I have is; can you say you are doing XP without pair-programming? because my tutor seems to think that I have to stick to all the practices otherwise I can't do it (nevermind if I am working alone). We can have external user input as well but due to the small timescales with part time work it may be more beneficial for myself to be the user as well, which is not what I prefer considering how I can get lost in the design.

  • How to represent an agile project to people focused on waterfall [closed]

    - by ahsteele
    Our team has been asked to represent our development efforts in a project plan. No one is unhappy with our work or questioning our ability to deliver, we are just participating in an IT cattle call for project plans. Trouble is we are an agile team and haven't thought about our work in terms of a formal project plan. While we have a general idea of what we are working on next we aren't 100% sure until we plan an iteration. Until now our team has largely operated in a vacuum and has not been required to present our methodology or metrics to outside parties. We follow most of the practices espoused in Extreme Programming. We hold quarterly planning meetings to have a general idea of the stories we are going to work on for a quarter. That said, our stories are documented on 3x5 cards and are only estimated at the beginning of the iteration in which they are going to be worked. After estimation we document the story in Team Foundation Sever. During an iteration, we attach code to stories and mark stories as completed once finished. From this data we are able to generate burn down and velocity charts. Most importantly we know our average velocity for an iteration keeping us from biting off more than we can chew. I am not looking to modify the way we do development but want to present our development activities in a report that someone only familiar with waterfall will understand. In What Does an Agile Project Plan Look Like, Kent McDonald does a good job laying out the differences between agile and waterfall project plans. He specifies the differences in consumable bullets: An agile project plan is feature based An Agile Project Plan is organized into iterations An Agile Project Plan has different levels of detail depending on the time frame An Agile Project Plan is owned by the Team Being able to explain the differences is great, but how best to present the data?

  • Modelling work-flow plus interaction with a database - quick and accessible options

    - by cjmUK
    I'm wanting to model a (proposed) manufacturing line, with specific emphasis on interaction with a traceability database. That is, various process engineers have already mapped the manufacturing process - I'm only interested in the various stations along the line that have to talk to the DB. The intended audience is a mixture of project managers, engineers and IT people - the purpose is to identify: points at which the line interacts with the DB (perhaps going so far as indicating the Store Procs called at each point, perhaps even which parameters are passed.) the communication source (PC/Handheld device/PLC) the communication medium (wireless/fibre/copper) control flow (if leak test fails, unit is diverted to repair station) Basically, the model will be used as a focus different groups on outstanding tasks; for example, I'm interested in the DB and any front-end app needed, process engineers need to be thinking about the workflow and liaising with the PLC suppliers, the other IT guys need to make sure we have the hardware and comms in place. Obviously I could just improvise in Visio, but I was wondering if there was a particular modelling technique that might particularly suit my needs or my audience. I'm thinking of a visual model with supporting documentation (as little as possible, as much as is necessary). Clearly, I don't want something that will take me ages to (effectively) learn, nor one that will alienate non-technical members of the project team. So far I've had brief looks at BPMN, EPC Diagrams, standard Flow Diagrams... and I've forgotten most of what I used to know about UML... And I'm not against picking and mixing... as long as it is quick, clear and effective. Conclusion: In the end, I opted for a quasi-workflow/dataflow diagram. I mapped out the parts of the manufacturing process that interact with the traceability DB, and indicated in a significantly-simplified form, the data flows and DB activity. Alongside which, I have a supporting document which outlines each process, the data being transacted for each process (a 'data dictionary' of sorts) and details of hardware and connectivity required. I can't decide whether is a product of genius or a crime against established software development practices, but I do think that is will hit the mark for this particular audience.

  • Topeka Dot Net User Group (DNUG) Meeting &ndash; April 6, 2010

    - by Robz / Fervent Coder
    Topeka DNUG is free for anyone to attend! Mark your calendars now! SPEAKER: Troy Tuttle is a self-described pragmatic agilist, and Kanban practitioner, with more than a decade of experience in delivering software in the finance and health industries and as a consultant. He advocates teams improve their performance through pursuit of better practices like continuous integration and automated testing. Troy is the founder of the Kansas City Limited WIP Society and is a speaker at local area groups on team related topics. He currently works as a Project Lead Consultant with AdventureTech Group of Kansas City, KS. TOPIC: Why Kanban? Kanban is receiving a large amount of attention recently. What does it offer compared to other approaches? Answering that question may require you to hit the “reset” button on previously held biases and assumptions. Kanban blends Lean thought with ideas from first generation agile methodologies. To get started with Kanban, we will examine what steps are necessary to establish a transparent, work-limited, pull system. We will highlight the perils of allowing too much work-in-progress and how it affects development performance. Once established, Kanban teams need only a few metrics and tools to monitor their performance and improvement. WHERE: Federal Home Loan Bank Topeka on the Security Benefit Campus – Directions?

  • Teaching OO to VBA developers [closed]

    - by Eugene
    I work with several developers that come from less object oriented background like (VB6, VBA) and are mostly self-taught. As part of moving away from those technologies we recently we started having weekly workshops to go over the features of C#.NET and OO practices and design principles. After a couple of weeks of basic introduction I noticed that they had a lot of problems implementing even basic code. For instance it took probably 15 minutes to implement a Stack.push() and a full hour to implement a simple Stack fully. These developers were trying to do things like passing top index as a parameter to the method, not creating an private array, using variables out of scope. But most of all not going through the "design (dia/mono)log" (I need something to do X, so maybe I'll make an array, or put it here). I am a little confused because they are smart people and are able to produce functional code in their traditional environments. I'm curious if anybody else has encountered a similar thing and if there are any particular resources, exercises, books, ideas that would be helpful in this circumstance.

  • How to diagram custom programming languages, non textual?

    - by Adam
    I've used and created domain-specific languages before, plenty of times (e.g. using yacc/lex). Normally we'd start with grammar written in BNF, and a bunch of keywords. This is easy to do, easy to share. Recently, I've started working with diagrammatic programming languages - closest parallel is circuit-diagrams in electronics, where it's very difficult to express ideas in text, but very easy to express them in wiring-diagrams. This is a new and novel problem for me: how to efficiently express these mini-languages, and share concepts in them with colleagues? (i.e. how to whiteboard-program within them. Actual programming is easy - you have physical components to hand) Are there tools for this? Or good/best practices (e.g. equivalent of "always use BNF as starting point for your new DSL, and use tools like yacc to generate the parser, compiler, etc"). My googlefu is proving weak - all I get is false positives for wiring diagrams, and UML editors (since these are custom languages, UML doesn't seem to help)

  • New Responsibilities

    - by Robert May
    With the start of the new year, I’m starting new responsibilities at Veracity. One responsibility that is staying constant is my love and evangelism of Agile.  In fact, I’ll be spending more time ensuring that all Veracity teams are performing agile, Scrum specifically, in a consistent manner so that all of our clients and consultants have a similar experience. Imagine, if you will, working for a consulting company on a project.  On that project, the project management style is Waterfall in iterations.  Now you move to another project and in that project, you’re doing real Scrum, but in both cases, you were told that what you were doing was Scrum.  Rather confusing.  I’ve found, however, that this happens on many teams and many projects.  Most companies simply aren’t disciplined enough to do Scrum.  Some think that being Agile means not being disciplined.  The opposite is true! So, my goals for Veracity are to make sure that all of our consultants have a consistent feel for Scrum and what it is and how it works and then to make sure that on the projects they’re assigned to, Scrum is appropriately applied for their situation.  This will help keep them happier, but also make switching to other projects easier and more consistent.  If we aren’t doing the project management on the project, we’ll help them know what good Agile practices should look like so that they can give good advice to the client, and so that if they move to another project, they have a consistent feel. I’m really looking forward to these new duties. Technorati Tags: Agile,Scrum

  • Introduction to Oracle ADF

    - by Arda Eralp
    The Oracle Application Development Framework (Oracle ADF) is an end-to-end application framework that builds on Java Platform, Enterprise Edition (Java EE) standards and open-source technologies. You can use Oracle ADF to implement enterprise solutions that search, display, create, modify, and validate data using web, wireless, desktop, or web services interfaces. Because of its declarative nature, Oracle ADF simplifies and accelerates development by allowing users to focus on the logic of application creation rather than coding details. Used in tandem, Oracle JDeveloper 11g and Oracle ADF give you an environment that covers the full development lifecycle from design to deployment, with drag-and-drop data binding, visual UI design, and team development features built in. In line with community best practices, applications you build using the Fusion web technology stack achieve a clean separation of business logic, page navigation, and user interface by adhering to a model-view-controller architecture. MVC architecture: The model layer represents the data values related to the current page The view layer contains the UI pages used to view or modify that data The controller layer processes user input and determines page navigation The business service layer handles data access and encapsulates business logic Each ADF module fits in the Fusion web application architecture. The core module in the framework is ADF Model, a data binding facility. The ADF Model layer enables a unified approach to bind any user interface to any business service, without the need to write code. The other modules that make up a Fusion web application technology stack are: ADF Business Components, which simplifies building business services. ADF Faces rich client, which offers a rich library of AJAX-enabled UI components for web applications built with JavaServer Faces (JSF). ADF Controller, which integrates JSF with ADF Model. The ADF Controller extends the standard JSF controller by providing additional functionality, such as reusable task flows that pass control not only between JSF pages, but also between other activities, for instance method calls or other task flows.

  • Plug-in based software design

    - by gekod
    I'm a software developer who is willing to improve his software design skills. I think software should not only work but have a solid and elegant design too to be reusable and extensive to later purposes. Now I'm in search of some help figuring out good practices for specific problems. Actually, I'm trying to find out how to design a piece of software that would be extensible via plug-ins. The questions I have are the following: Should plug-ins be able to access each others functionality? This would bring dependencies I guess. What should the main application offer to the plug-ins if I want to let's say develop a multimedia software which would play videos and music but which could later on get functionality added over plug-ins that would let's say be able to read video status (time, bps, ...) and display it. Would this mean that the player itself would have to be part of the main program and offer services to plug-ins to get such information or would there be a way to develop the player as a plug-in also but offer in some way the possibility to other plug-ins to interact with it? As you see, my questions are mainly for learning purposes as I strive to improve my software development skills. I hope to find help here and apologize if something is wrong with my question.

  • What's the best practice to do SOA exception handling?

    - by sun1991
    Here's some interesting debate going on between me and my colleague when coming to handle SOA exceptions: On one side, I support what Juval Lowy said in Programming WCF Services 3rd Edition: As stated at the beginning of this chapter, it is a common illusion that clients care about errors or have anything meaningful to do when they occur. Any attempt to bake such capabilities into the client creates an inordinate degree of coupling between the client and the object, raising serious design questions. How could the client possibly know more about the error than the service, unless it is tightly coupled to it? What if the error originated several layers below the service—should the client be coupled to those lowlevel layers? Should the client try the call again? How often and how frequently? Should the client inform the user of the error? Is there a user? By having all service exceptions be indistinguishable from one another, WCF decouples the client from the service. The less the client knows about what happened on the service side, the more decoupled the interaction will be. On the other side, here's what my colleague suggest: I believe it’s simply incorrect, as it does not align with best practices in building a service oriented architecture and it ignores the general idea that there are problems that users are able to recover from, such as not keying a value correctly. If we considered only systems exceptions, perhaps this idea holds, but systems exceptions are only part of the exception domain. User recoverable exceptions are the other part of the domain and are likely to happen on a regular basis. I believe the correct way to build a service oriented architecture is to map user recoverable situations to checked exceptions, then to marshall each checked exception back to the client as a unique exception that client application programmers are able to handle appropriately. Marshall all runtime exceptions back to the client as a system exception, along with the stack trace so that it is easy to troubleshoot the root cause. I'd like to know what you think about this? Thank you.

  • Explicitly pass context object versus injecting with IoC

    - by SonOfPirate
    I have a layered service application where the service layer delegates operations into the domain layer for execution. Many of these operations need to know the context under which they are operation. (The context included the identity of the current user, culture information, etc. received from the caller.) For example, I have an API method that returns a list of announcements. The list is based on the current user's role and each announcement is localized to their culture. The API is a thin-facade that delegates to an Application Service in my domain layer. The Application Service method obviously needs to know the context of the current request/operation as another call to the same API from another user should result in a different list. Within this method, we also have logging that uses some of the context information so we a clear understanding of the context when the operation was performed (this is especially useful if something goes wrong.) While this is a contrived example, in the real world, my Application Services will coordinate operations with many collaborative components, any number of them also needing the context information. My choice is to pass the context to the Application Service which would then pass it with any calls to collaborators or have the IoC container satisfy the dependency the Application Service and any collaborators have on the context. I am wondering if it is considered good/bad, best practices/code smell, etc. if I pass the context object as a parameter to the domain methods or if injecting the context via an IoC container is preferred. (EDIT: I should mention that the context object is instantiated per-request.)
