• Porting Ruby/NCruses Rogue-Like to .NET and FlatRedBall

  - by ashes999

  I created an awesome rogue-like game in Ruby. For the GUI, I used NCurses. Since I'm using FlatRedBall as my engine of choice for Silverlight game development, I want to port this game over. What is the best way to efficiently doing this, and what are the pitfalls I should expect? For example, Ruby is object-oriented, like C#, and I should be able to just convert (rewrite) classes one by one. However, I will run into issues like: NCurses API. I need to possibly create my own notions of a "Window", or else rewrite GUI code. It's one class, but it's BIG. Mix-Ins. These are essentially aspect-oriented development. There are a couple of solutions in .NET, like dynamic classes. What else? Also, I should mention that I want to create a C# application out of this. As much as possible, I'll dump reusable and helper code, algorithms, etc. into separate projects and generate reusable DLLs.

• ASP.NET MVC Application In Action - I (DailyJournal)

  - by Rajesh Pillai

  Its been long due I was planning to write an article on creating some useful ASP.NET MVC application. I have code named it "DailyJournal". Its a simple application which allows creation of multiple activities and assign tasks to these activities. Its' kind of "Yet another Task/Todo application". The credentials which you can use with the attached demo application is shown below.   Collapse Copy Code User Name : admin Password : admin123 Framework/Libraries Used ASP.NET MVC jQuery + jQuery UI (for ajax and UI) ELMAH for Error logging Warning Ahead This is just a rough draft and so I am putting down some of the known limitation. Some points of warning before we move further with this application. This is just an early prototype. As such many of the design principles have been ignored. But, I try to cover that up in the next update once I get my head around this. The application in its current state supports the following features Create users Assign Activities to users Assign tasks to activities Assign a status to a task The user creation/authentication is being done by the default Membership provider. Most of the activities are highly visual i.e. you can drag-drop task to different areas, in-place edition of task details and so on.   The following are the current issues with the design which I promise to refactor in the second version. No Validations Fat Controller XSS/CSS vulnerable No Service model/abstraction yet. For the demo LINQ to SQL is implemented. No separation of layers UI Design et el... This is just an extract.  For source code and more information proceed to http://www.codeproject.com/KB/aspnet/mvcinaction.aspx Hope you like this!

• Podcast Show Notes: Old Habits Die Hard in the New SOA World

  - by OTN ArchBeat

  Like the previous series, the latest OTN ArchBeat Podcast program was also recorded in a hotel room just around the corner from Oracle OpenWorld in San Francisco just a few weeks ago. The gathered experts, all members of the OTN architect community, agreed to participate in an informal roundtable discussion of what's happening in Service Oriented Architecture. As you'll hear, the conversation ranged from the maturity of Service Oriented Architecture technology and tools, to the the lingering and typically self-imposed problems that can prevent organizations from realizing the full potential of SOA, to what SOA means in the era of *aaS, mobile computing, and big data. Hajo Normann, Torsten Winterberg, Ronald van Luttikhuizen, and Guido Schmutz (L-R) Hajo Normann, Torsten Winterberg, Danilo Schmeidel, and Lonneke Dikmans (L-R) The Panelists (Listed alphabetically) Lonneke Dikmans, Managing Partner at Vennster, Oracle ACE Director Ronald van Luttikuhuizen, Managing Partner at Vennster, Oracle ACE Director Hajo Normann, SOA & BPM Lead for ASG at Accenture, Oracle ACE Director Danilo Schmiedel, Solution Architect at Opitz Consulting Guido Schmutz, Technology Manager for SOA/BPM and Architecture Board at Trivadis, Oracle ACE Director Torsten Winterberg, Director of Strategy and Innnovation and head of SOA Competence Center at Opitz Consulting, Oracle ACE Director The Conversation Listen to Part 1: SOA technology and tools are mature, says this panel of experts, but why do some organizations still struggle to take full advantage of industrialized SOA? Listen to Part 2 (Nov 6): Human nature and a lack of trust among stakeholders can thwart successful SOA. Can a marketplace approach and social tools improve the situation? Listen to Part 3 (Nov 13): Do SOA stakeholders recognize the problems caused by poor communication among siloed service development teams? Coming Soon SOA and B2B: The authors of Getting Started with Oracle SOA B2B Integration: A Hands-On Tutorial discuss Business to Business capabilities in Oracle SOA Suite 11g.

• Reset / Remove - Google Keywords

  - by Herr Kaleun

  Summary: My site is ranking for filthy keywords and i would like to remove them from google ranking/keywords. Background: My server was hacked using the timthumb exploit/security vulnerability, apparently i was the last person on earth to read the news about the exploit, several months after it appeared. Anyway, the "hacker" was so friendly to modify the index.php file in such a fashion, that it generated random sexual oriented keywords if the website is fetched as google-bot. So if you would fetch it as google bot/it gets indexed, you would get randomly generated keywords like: sex videos teenager teen sex adult sex preteen A LINK TO A RANDOM CONTENT OF MY WEBPAGE anime sex videos a rough list something similar to that, about 180-200 per page. I've discovered it far too late, so that google had me indexed for the words "sex" and certain adult oriented keywords, about roughly 2000. I've removed all the content, toke the site down, replaced the index.php with a static HTML and added a "ERROR 410" title to the website so that the content is no longer here and removed permanently. I've also applied for a manual review of my website, about 1.5 months ago but still, the keywords are there, and very strange, some of the keyword rankings actually "improve" over time. Here are some screenshots from webmasters tools: Question: How can i remove this filthy keywords and re-rank my website as a "normal" website on the fastest way? I want to "REMOVE" the keywords if possible. Please help me or point me into a direction. Thank you

• Introducing Deep Fried Devcast

  - by Matt Christian

  I've been working on a new podcast for the game development community called the Deep Fried Devcast.  Currently we are in pre-production but should have some episodes up in the near future.  Here is a quick FAQ about the show: What is the Deep Fried Devcast? The Deep Fried Devcast is a bi-weekly show all about game development.  The show will feature developer interviews, a focus on the technical aspects of game development (programming, technical design), the business of team game development (time management, project management), and other areas focused around the actual development of games. Wait, no game design?  No game discussions?! Calm down, calm down.  Although the focus of the podcast is on the technical aspects of game dev, there will be episodes and content focused on all areas of the gaming industry, including discussion on design, story, recent game releases, games we've been playing, etc...  Anything could show up in the Deep Fried Devcast and nothing is off limits. How can I help? We're always looking for new content ideas, emails, and anything you want to send us (within some kind of reason!).  You can even be a guest host if you want!  Email us at: deepfrieddevcast [AT] gmail [DOT] com Where's the podcast?! We're still recording it!  Don't worry, it will be up soon.  Keep an eye on www.deepfrieddevcast.com for the latest updates (that will be up soon too!).

• Star Trek inspired home automation visualisation

  - by Zak McKracken

  I’ve always been a more or less active fan of Star Trek. During the construction phase of my house I started coding a GUI for controlling the house which has an EIB. Just for fun I designed a version inspired by the LCARS design used in Star Trek TNG and showed this to my wife. I showed her several designs before but this was the only one, she really liked. So I decided to go on with this. I started a C# WinForms application. The software runs on a wall mounted Shuttle Barebone-PC. First plan was an industrial panel-pc but the processor was too slow. The now-used Atom is ok. I started with the LCARS-controls found on Codeproject. Since the classic LCARS design divides the screen into two parts this tended to be impracticable, so I used my own design For now the software is able to: Switch lights/wall outlets Show current temperatures for all room controllers Show outside temperature with a 24h trend chart Show the status of the two heat pumps Provide an alarm clock (e.g. for cooking) Play internet radio streams Control absence Mute the door bell Speak status messages via speech synthesis For now, I’m working on an integration of my electric meter. The main heat pump and the electric meter are connected to my LAN. I also tried some speech recognition, but I’ve problems with the microphone. I't’s working when you are right in front of the PC, but not far away, let’s say on the other side of the room. So this is the main view. The table displays raw values which are sent over the EIB – completely useless but looks great For each floor I have a different view. Here you can see the temperatures and check the status of the lights (the buttons are blinking when a light is switched on) This is the view for the heat pump:   Next step would be to integrate a control of my squeezebox server (I use different Squeezeboxes through the house as a multiroom audio solution)

• Top Fusion Apps User Experience Guidelines & Patterns That Every Apps Developer Should Know About

  - by ultan o'broin

  We've announced the availability of the Oracle Fusion Applications user experience design patterns. Developers can get going on these using the Design Filter Tool (or DeFT) to select the best pattern for their context of use. As you drill into the patterns you will discover more guidelines from the Applications User Experience team and some from the Rich Client User Interface team too that are also leveraged in Fusion Apps. All are based on the Oracle Application Development Framework components. To accelerate your Fusion apps development and tailoring, here's some inside insight into the really important patterns and guidelines that every apps developer needs to know about. They start at a broad Fusion Apps information architecture level and then become more granular at the page and task level. Information Architecture: These guidelines explain how the UI of an Oracle Fusion application is constructed. This enables you to understand where the changes that you want to make fit into the oveall application's information architecture. Begin with the UI Shell and Navigation guidelines, and then move onto page-level design using the Work Areas and Dashboards guidelines. UI Shell Guideline Navigation Guideline Introduction to Work Areas Guideline Dashboards Guideline Page Content: These patterns and guidelines cover the most common interactions used to complete tasks productively, beginning with the core interactions common across all pages, and then moving onto task-specific ones. Core Across All Pages Icons Guideline Page Actions Guideline Save Model Guideline Messages Pattern Set Embedded Help Pattern Set Task Dependent Add Existing Object Pattern Set Browse Pattern Set Create Pattern Set Detail on Demand Pattern Set Editing Objects Pattern Set Guided Processes Pattern Set Hierarchies Pattern Set Information Entry Forms Pattern Set Record Navigation Pattern Set Transactional Search and Results Pattern Group Now, armed with all this great insider information, get developing some great-looking, highly usable apps! Let me know in the comments how things go!

• Advantages and Disadvantages of the Waterfall Methodology

  In my personal opinion I believe the waterfall method is one of the worst methodologies to use when developing larger systems because it leaves is no room for mistakes. As the name implies the waterfall methodology does not allow  for projects to go back up stream to recover from design errors, missing and/or limited requirements. In addition, hidden bugs are not usually found until the testing phase. This can prove to be very costly and time consuming to the developer and the client. According to NCycles.com, the waterfall methodology structures a project into separate stages with defined deliverables from each phase. Define Design Code Test Implement Document and Maintain The advantages found by Ncycle.com to this methodology are: Ease in analyzing potential changes  Ability to coordinate larger teams, even if geographically distributed Can enable precise dollar budget Less total time required from Subject Matter Experts The disadvantages found by Ncycle.com to this methodology are: Lack of flexibility Hard to predict all needs in advance Intangible knowledge lost between hand-offs Lack of team cohesion Design flaws not discovered until the Testing phase References: NCycles.com  (2002).

• Applying Interactive Sorting to Multiple Columns in Reporting Services

  - by smisner

  A nice feature that appeared first in SQL Server 2008 is the ability to allow the user to click a column header to sort that column. It defaults to an ascending sort first, but you can click the column again to switch to a descending sort. You can learn more about interactive sorts in general at the Adding Interactive Sort to a Data Region in Books Online. Not mentioned in the article is how to apply interactive sorting to multiple columns, hence the reason for this post! Let’s say that I have a simple table like this: To enable interactive sorting, I open the Text Box properties for each of the column headers – the ones in the top row. Here’s an example of how I set up basic interactive sorting: Now when I preview the report, I see icons appear in each text box on the header row to indicate that interactive sorting is enabled. The initial sort order that displays when you preview the report depends on how you design the report. In this case, the report sorts by Sales Territory Group first, and then by Calendar Year. Interactive sorting overrides the report design. So let’s say that I want to sort first by Calendar Year, and then by Sales Territory Group. To do this, I click the arrow to the right of Calendar Year, and then, while pressing the Shift key, I click the arrow to the right of Sales Territory Group twice (once for ascending order and then a second time for descending order). Now my report looks like this: This technique only seems to work when you have a minimum of three columns configured with interactive sorting. If I remove the property from one of the columns in the above example, and try to use the interactive sorting on the remaining two columns, I can sort only the first column. The sort on the second column gets ignored. I don’t know if that’s by design or a bug, but I do know that’s what I’m experiencing when I try it out!

• A new mission statement for my school's algorithms class

  - by Eric Fode

  The teacher at Eastern Washington University that is now teaching the algorithms course is new to eastern and as a result the course has changed drastically mostly in the right direction. That being said I feel that the class could use a more specific, and industry oriented (since that is where most students will go, though suggestions for an academia oriented class are also welcome) direction, having only worked in industry for 2 years I would like the community's (a wider and much more collectively experienced and in the end plausibly more credible) opinion on the quality of this as a statement for the purpose an algorithms class, and if I am completely off target your suggestion for the purpose of a required Jr. level Algorithms class that is standalone (so no other classes focusing specifically on algorithms are required). The statement is as follows: The purpose of the algorithms class is to do three things: Primarily, to teach how to learn, do basic analysis, and implement a given algorithm found outside of the class. Secondly, to teach the student how to model a problem in their mind so that they can find a an existing algorithm or have a direction to start the development of a new algorithm. Third, to overview a variety of algorithms that exist and to deeply understand and analyze one algorithm in each of the basic algorithmic design strategies: Divide and Conquer, Reduce and Conquer, Transform and Conquer, Greedy, Brute Force, Iterative Improvement and Dynamic Programming. The Question in short is: do you agree with this statement of the purpose of an algorithms course, so that it would be useful in the real world, if not what would you suggest?

• What is your most preferred method of site pagination?

  - by John Smith

  There seem to be quite a few implementations of this feature. Some sites like like Stackexchange have it laid out like this: [1][2][3][4][5] ... [954][Next] Other sites like game forums may have something like this: [1][2][3] ... [10] ... [50] ... [500] ... [954][Next] Some sites like webcomics (XKCD comes to mind) have it laid out like this: [Last][Prev][Random][Next][First] Reddit has a very simple pagination with only: [Prev][Next] Sites like Stackexchange and Google also allow you to change how many results you want per page. Personally, I have never used this feature. Is it even worth including or does it just further confuse the design with needless features? Personally, I have only ever seen the need for the webcomic style (without the random). If I need to go to a specific page (which is very, very rare) then I can just edit the address bar. Is it good design to make something more complex for rare occasions where it might make save the user some time? Is having to edit the address bar to navigate the site effectively in some circumstances bad design?

• Graduate expectations versus reality

  - by Bobby Tables

  When choosing what we want to study, and do with our careers and lives, we all have some expectations of what it is going to be like. Now that I've been in the industry for almost a decade, I've been reflecting a bit on what I thought (back when I was studying Computer Science) programming working life was going to be like, and how it's actually turning out to be. My two biggest shocks (or should I say, broken expectations) by far are the sheer amount of maintenance work involved in software, and the overall lack of professionalism: Maintenance: At uni, we were all told that the majority of software work is maintenance of existing systems. So I knew to expect this in the abstract. But I never imagined exactly how overwhelming this would turn out to be. Perhaps it's something I mentally glazed over, and hoped I'd be building cool new stuff from scratch a lot more. But it really is the case that most jobs are overwhelmingly maintenance, bug fixing, and support oriented. Lack of professionalism: At uni, I always had the impression that commercial software work is very process-oriented and stringently engineered. I had images of ISO processes, reams of technical documentation, every feature and bug being strictly documented, and a generally professional environment. It came as a huge shock to realise that most software companies operate no differently to a team of students working on a large semester-long project. And I've worked in both the small agile hack shop, and the medium sized corporate enterprise. While I wouldn't say that it's always been outright "unprofessional", it definitely feels like the software industry (on the whole) is far from the strong engineering discipline that I expected it to be. Has anyone else had similar experiences to this? What are the ways in which your expectations of what our profession would be like were different to the reality?

• Metaphor for task synchronization [closed]

  - by nkint

  I'm looking for a metaphor. A friend of mine taught me to use metaphors from nature, everyday life, math, and use them to design my projects. They can help in creating a better design or better understanding or the problem, and they are cool. Now I'm working on a project with hardware and micro-controllers in C. For convenience, I have decided to use multiple micro-controllers as co-processor units for real-time (the slaves) and a master. This has saved me a lot of headache: I can code the main logic in the master without paying too much attention to super optimizing everything; I don't care if I need some blocking-call; I don't worry about serial communication with the computer. I just send messages to the slaves and they are super fast super in real time. I like my design and it seems to work well. So here are the important concepts that I'm trying capture in the metaphor: hierarchy of processing Not using one big brain but rather several small, distributed brain units using distributed power or resources I'm looking for a good metaphor for this concept of having one unit synchronize the work of all the others. Preferably, the metaphor would come from nature, biology, or zoology.

• 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 Iron Bird Approach

  - by David Paquette

  It turns out that designing software is not so different than designing commercial aircraft.  I just finished watching a video that talked about the approach that Bombardier is taking in designing the new C Series aircraft.  I was struck by the similarities to agile approaches to software design.  In the video, Bombardier describes how they are using an Iron Bird to work through a number of design questions in advance of ever having a version of the aircraft that can ever be flown.  The Iron Bird is a life size replica of the plane.  Based on the name, I would assume the plane is built in a very heavy material that could never fly.  Using this replica, Bombardier is able to valid certain assumptions such as the length of each wire in the electric system.  They are also able to confirm that some parts are working properly (like the rudders).  They even go as far as to have a complete replica of the cockpit.  This allows Bombardier to put pilots in the cockpit to run through simulated take-off and landing sequences. The basic tenant of the approach seems to be Validate your design early with working prototypes Get feedback from users early, well in advance of finishing the end product   In software development, we tend to think of ourselves as special.  I often tell people that it is difficult to draw comparisons to building items in the physical world (“Building software is nothing like building a sky scraper”).  After watching this video, I am wondering if designing/building software is actually a lot like designing/building commercial aircraft.   Watch the video here (http://www.theglobeandmail.com/report-on-business/video/video-selling-the-c-series/article4400616/)

• An Interview with JavaOne Rock Star Martijn Verburg

  - by Janice J. Heiss

  An interview with JavaOne Rock Star Martijn Verburg, by yours truly, titled “Challenging the Diabolical Developer: A Conversation with JavaOne Rock Star Martijn Verburg,” is now up on otn/java. Verburg, one of the leading movers and shakers in the Java community, is well known for his ‘diabolical developer” talks at JavaOne where he uncovers some of the worst practices that Java developers are prone to. He mentions a few in the interview: * “A lack of communication: Software development is far more a social activity than a technical one; most projects fail because of communication issues and social dynamics, not because of a bad technical decision. Sadly, many developers never learn this lesson.* No source control: Some developers simply store code in local file systems and e-mail the code in order to integrate their changes; yes, this still happens.* Design-driven design: Some developers are inclined to cram every design pattern from the Gang of Four (GoF) book into their projects. Of course, by that stage, they've actually forgotten why they're building the software in the first place.” He points to a couple of core assumptions and confusions that lead to trouble: “One is that developers think that the JVM is a magic box that will clean up their memory and make their code run fast, as well as make them cups of coffee. The JVM does help in a lot of cases, but bad code can and will still lead to terrible results! The other trend is to try to force Java (the language) to do something it's not very good at, such as rapid Web development. So you get a proliferation of overly complex frameworks, libraries, and techniques trying to get around the fact that Java is a monolithic, statically typed, compiled, OO environment. It's not a Golden Hammer!” Verburg has many insightful things to say about how to keep a Java User Group (JUG) going, about the “Adopt a JSR” program, bugathons, and much more.

• Does the HTMLEditor control raise any client-side events?

  - by SAMIR BHOGAYTA

  The HTML Editor has three modes: Design, HTML Text and preview mode. Design mode is in an IFrame. HTML Text is prensented in a TextArea and preview mode is in another Iframe. The code rendered about these three modes is as below. iframe id="editor1_ctl02_ctl00" name="editor1_ctl02_ctl00" marginheight="0" marginwidth="0" frameborder="0" src="javascript:false;" style="height:100%;width:100%;display:none;border-width:0px;" /iframe textarea id="editor1_ctl02_ctl01" class="ajax__htmleditor_htmlpanel_default" style="height:100%;width:100%;display:none;" /textarea iframe id="editor1_ctl02_ctl02" name="editor1_ctl02_ctl02" marginheight="0" marginwidth="0" frameborder="0" src="javascript:false;" style="height:100%;width:100%;display:none;border-width:0px;" /iframe In design mode, we can use the following JavaScript to append a callback function in onKeypress event. script type="text/javascript" var count = 0; function pageLoad() { $get('editor1_ctl02_ctl00').contentWindow.document.body.onkeypress = function() { count++; $get('cc').innerHTML = "you input " + count + "charactors"; }; } /script As a same way, you can append another keypress event on TextArea and preview IFrame.

• 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.

• How do you KISS?

  - by Conor

  The KISS principle is a highly quoted design mantra. The aim of this principle is to stamp out unnecessary complexity on a project. This is a good thing, saving time, energy and money. It can lead to a relatively stress free implementation and a simple, elegant, maintainable end product. A lot of discussion on KISS provides mechanisms to simplify requirements, design and implementation. Things that spring to mind include: avoid scope creep; simple obvious design and code; minimal run-time dependencies; refactoring to maintain simplicity; etc. However there are a lot of implicit things that we do to KISS. Examples: small team sizes; minimal management layers; tidy desk; mastery of a single IDE; clear concise error messages; scripts to automate/encapsulate tasks; etc Why KISS practices do you apply? How have they been of benefit? I'm especially interested in non-obvious practices.

• Should components have sub-components in a component-based system like Artemis?

  - by Daniel Ingraham

  I am designing a game using Artemis, although this is more of philosophical question about component-based design in general. Let's say I have non-primitive data which applies to a given component (a Component "animal" may have qualities such as "teeth" or "diet"). There are three ways to approach this in data-driven design, as I see it: 1) Generate classes for these qualities using "traditional" OOP. I imagine this has negative implications for performance, as systems then must be made aware of these qualities in order to process them. It also seems counter to the overall philosophy of data-driven design. 2) Include these qualities as sub-components. This seems off, in that we are now confusing the role of components with that of entities. Moreover out of the box Artemis isn't capable of mapping these subcomponents onto their parent components. 3) Add "teeth", "diet", etc. as components to the overall entity alongside "animal". While this feels odd hierarchically, it may simply be a peculiarity of component-based systems. I suspect 3 is the correct way to think about things, but I was curious about other ideas.

• How to apply verification and validation on the following example

  - by user970696

  I have been following verification and validation questions here with my colleagues, yet we are unable to see the slight differences, probably caused by language barrier in technical English. An example: Requirement specification User wants to control the lights in 4 rooms by remote command sent from the UI for each room separately. Functional specification The UI will contain 4 checkboxes labelled according to rooms they control. When a checkbox is checked, the signal is sent to corresponding light. A green dot appears next to the checkbox When a checkbox is unchecked, the signal (turn off) is sent to corresponding light. A red dot appears next to the checkbox. Let me start with what I learned here: Verification, according to many great answers here, ensures that product reflects specified requirements - as functional spec is done by a producer based on requirements from customer, this one will be verified for completeness, correctness). Then design document will be checked against functional spec (it should design 4 checkboxes..), and the source code against design (is there a code for 4 checkboxes, functions to send the signals etc. - is it traceable to requirements). Okay, product is built and we need to test it, validate. Here comes our understanding trouble - validation should ensure the product meets requirements for its specific intended use which is basically business requirement (does it work? can I control the lights from the UI?) but testers will definitely work with the functional spec, making sure the checkboxes are there, working, labelled, etc. They are basically checking whether the requirements in functional spec were met in the final product, isn't that verification? (should not be, lets stick to ISO 12207 that only validation is the actual testing)
