• CAM v2.0 ships – all new foundation version

  - by drrwebber

  The latest release of the CAM editor toolset is now available on Sourceforge.net – search NIEM. In this all new version the support from Oracle has enabled a transformation of the editor underpinning Java framework and results in 3x performance improvement and 50% better memory utilization. The result of nearly six months of improvements are catalogued in the release notes. http://sourceforge.net/projects/camprocessor/files/CAM%20Editor/Releases/2.0/CAM_Editor_2-0_Release_Notes.pdf/download However here I’d like to talk about the strategic vision and highlight specific new go to features that make a difference for exchange schema designers and with a focus on the NIEM community. So why is this a foundation version? Basically the new drag and drop designer tool allows you to tailor your own dictionary collection of components and then simply select and position those into your resulting exchange structure. This is true global reuse enabled from a canonical domain dictionary collection. So instead of grappling with XSD Schema syntax, or UML model nuances – this is straightforward direct WYSIWYG visual engineering – using familiar sets of business components. Then the toolkit writes the complex XSD Schema for you, along with test samples, documentation, XMI/UML models, Mindmaps and more. So how do you get a set of business components? The toolkit allows you to harvest these from existing schema collections or enterprise data models, or as in the case of NIEM, existing domain dictionary collections. I’ve been using this for the latest IEEE/OASIS/NIST initiative on a Common Data Format (CDF) for elections management systems. So you can download those from OASIS and see how this can transform how you build actual business exchanges – improving the quality, consistency and usability – and dramatically allowing automated generation of artifacts you only dreamed of before – such as a model of your entire major exchange collection components. http://www.oasis-open.org/committees/documents.php?wg_abbrev=election So what we have here is a foundation version – setting the scene and the basis for changing how people can generate and manage information exchanges. A foundation built using the OASIS CAM standard combined with aspects of the NIEM Naming and Design Rules and the UN/CEFACT Core Components specifications and emerging work on OASIS CIQ name and address and ANSI/ISO code list schema. We still have a raft of work to do to integrate this into SOA best practices and extend the dictionary capabilities to assist true community development. Answering questions such as: - How good is my canonical component collection? - How much reuse is really occurring? - What inconsistencies and extensions are there in the dictionary components? Expect us to begin tackling these areas now that the foundation is in place. The immediate need is to develop training and self-start materials – so we will be focusing there for the next couple of months and especially leading up to the IJIS industry event in July in New Jersey, and the NIEM NTE event in August in Philadelphia. http://sourceforge.net/projects/camprocessor

• Do we need to adopt a black-box asset our project is inheriting from its predecessor?

  - by Tom Anderson

  Our client has an eCommerce site which was developed by an in-house team, and is now showing its age. I work for a firm brought in as external contractors to build a replacement. Part of the current site is a Flash viewer applet which displays media about the product - zoom-able images, 360-degree views, movies, and so on. We need to show the same media the current site does, so we are simply reusing the viewer. The viewer is embedded on a page in the usual way, and told what media to show by means of an XML file it loads from our server, which is pretty simple for us to generate. We've got this working; it was pretty straightforward. But what else do we need to do? The thing is, as far as we're concerned, the viewer is a binary blob which is served from the client's content-distribution network. We embed it, feed it some XML, and it does its job, but we have no power over its internals. It's completely opaque to us - a black box. We can use it to do what it does, but we can't change it, so if we ever need to do something different, we're stuffed. We're building this site for the client, and when we're done, we'll hand it over for them to maintain. We won't be doing the maintenance ourselves. There's a small team within the client who are working as part of our team, and who will be the ones doing the maintenance. That team only includes one person from the team that built the old site, and it's not someone who knows the image viewer. The people who do know the image viewer are not slated to join our team when our system replaces theirs - they'll be moved to other projects. The documentation on the viewer is extremely thin, and as far as i know doesn't cover the internals at all. My worry is that if someone doesn't take some positive action, all knowledge of the internal workings of the viewer - even down to where the source code for it is - will be lost. It's possible it already has been. Is this something to worry about? If so, whose job is it to worry about it? What should they do about it once they've got worried?

• Fraud and Anomaly Detection using Oracle Data Mining YouTube-like Video

  - by chberger

  I've created and recorded another YouTube-like presentation and "live" demos of Oracle Advanced Analytics Option, this time focusing on Fraud and Anomaly Detection using Oracle Data Mining.  [Note:  It is a large MP4 file that will open and play in place.  The sound quality is weak so you may need to turn up the volume.] Data is your most valuable asset. It represents the entire history of your organization and its interactions with your customers.  Predictive analytics leverages data to discover patterns, relationships and to help you even make informed predictions.   Oracle Data Mining (ODM) automatically discovers relationships hidden in data.  Predictive models and insights discovered with ODM address business problems such as:  predicting customer behavior, detecting fraud, analyzing market baskets, profiling and loyalty.  Oracle Data Mining, part of the Oracle Advanced Analytics (OAA) Option to the Oracle Database EE, embeds 12 high performance data mining algorithms in the SQL kernel of the Oracle Database. This eliminates data movement, delivers scalability and maintains security.  But, how do you find these very important needles or possibly fraudulent transactions and huge haystacks of data? Oracle Data Mining’s 1 Class Support Vector Machine algorithm is specifically designed to identify rare or anomalous records.  Oracle Data Mining's 1-Class SVM anomaly detection algorithm trains on what it believes to be considered “normal” records, build a descriptive and predictive model which can then be used to flags records that, on a multi-dimensional basis, appear to not fit in--or be different.  Combined with clustering techniques to sort transactions into more homogeneous sub-populations for more focused anomaly detection analysis and Oracle Business Intelligence, Enterprise Applications and/or real-time environments to "deploy" fraud detection, Oracle Data Mining delivers a powerful advanced analytical platform for solving important problems.  With OAA/ODM you can find suspicious expense report submissions, flag non-compliant tax submissions, fight fraud in healthcare claims and save huge amounts of money in fraudulent claims  and abuse.   This presentation and several brief demos will show Oracle Data Mining's fraud and anomaly detection capabilities.

• In an Entity-Component-System Engine, How do I deal with groups of dependent entities?

  - by John Daniels

  After going over a few game design patterns, I have settle with Entity-Component-System (ES System) for my game engine. I've reading articles (mainly T=Machine) and review some source code and I think I got enough to get started. There is just one basic idea I am struggling with. How do I deal with groups of entities that are dependent on each other? Let me use an example: Assume I am making a standard overhead shooter (think Jamestown) and I want to construct a "boss entity" with multiple distinct but connected parts. The break down might look like something like this: Ship body: Movement, Rendering Cannon: Position (locked relative to the Ship body), Tracking\Fire at hero, Taking Damage until disabled Core: Position (locked relative to the Ship body), Tracking\Fire at hero, Taking Damage until disabled, Disabling (er...destroying) all other entities in the ship group My goal would be something that would be identified (and manipulated) as a distinct game element without having to rewrite subsystem form the ground up every time I want to build a new aggregate Element. How do I implement this kind of design in ES System? Do I implement some kind of parent-child entity relationship (entities can have children)? This seems to contradict the methodology that Entities are just empty container and makes it feel more OOP. Do I implement them as separate entities, with some kind of connecting Component (BossComponent) and related system (BossSubSystem)? I can't help but think that this will be hard to implement since how components communicate seem to be a big bear trap. Do I implement them as one Entity, with a collection of components (ShipComponent, CannonComponents, CoreComponent)? This one seems to veer way of the ES System intent (components here seem too much like heavy weight entities), but I'm know to this so I figured I would put that out there. Do I implement them as something else I have mentioned? I know that this can be implemented very easily in OOP, but my choosing ES over OOP is one that I will stick with. If I need to break with pure ES theory to implement this design I will (not like I haven't had to compromise pure design before), but I would prefer to do that for performance reason rather than start with bad design. For extra credit, think of the same design but, each of the "boss entities" were actually connected to a larger "BigBoss entity" made of a main body, main core and 3 "Boss Entities". This would let me see a solution for at least 3 dimensions (grandparent-parent-child)...which should be more than enough for me. Links to articles or example code would be appreciated. Thanks for your time.

• Should custom data elements be stored as XML or database entries?

  - by meteorainer

  There are a ton of questions like this, but they are mostly very generalized, so I'd like to get some views on my specific usage. General: I'm building a new project on my own in Django. It's focus will be on small businesses. I'd like to make it somewhat customizble for my clients so they can add to their customer/invoice/employee/whatever items. My models would reflect boilerplate items that all ModelX might have. For example: first name last name email address ... Then my user's would be able to add fields for whatever data they might like. I'm still in design phase and am building this myself, so I've got some options. Working on... Right now the 'extra items' models have a FK to the generic model (Customer and CustomerDataPoints for example). All values in the extra data points are stored as char and will be coerced/parced into their actual format at view building. In this build the user could theoretically add whatever values they want, group them in sets and generally access them at will from the views relavent to that model. Pros: Low storage overhead, very extensible, searchable Cons: More sql joins My other option is to use some type of markup, or key-value pairing stored directly onto the boilerplate models. This coul essentially just be any low-overhead method weather XML or literal strings. The view and form generated from the stored data would be taking control of validation and reoganizing on updates. Then it would just dump the data back in as a char/blob/whatever. Something like: <datapoint type='char' value='something' required='true' /> <datapoint type='date' value='01/01/2001' required='false' /> ... Pros: No joins needed, Updates for validation and views are decoupled from data Cons: Much higher storage overhead, limited capacity to search on extra content So my question is: If you didn't live in the contraints impose by your company what method would you use? Why? What benefits or pitfalls do you see down the road for me as a small business trying to help other small businesses? Just to clarify, I am not asking about custom UI elements, those I can handle with forms and template snippets. I'm asking primarily about data storage and retreival of non standardized data relative to a boilerplate model.

• How to keep balance / Unlock items / achievement rules

  - by Mark Knol

  I'm working on an engine for a game, too learn javascript and just because its fun. I'm a flashdeveloper, I know how to build websites. Now making games is a different challenge, javascript is a challenge, but I'd love to learn how to structure code and what patterns are common. I dont mind if the game ever finish, I'm mostly interested in the programming part of it. I dont have a particular endresult in mind, so I'll see where it takes me. I currently have a system where you can buy items. The items cost a specified amount of gold, silver, diamonds etc. When you have selected and bought the item, it takes time before getting rewarded. When time is over, you are getting rewarded with other properties (gold, energy, diamonds). For example, you can buy an apple for 50gold, It takes a minute, you get rewarded with 75energy. Or if you take a run, it cost 50energy, it takes 5minutes, reward is 25gold and 25silver. These definitions is what i call actions. Currently I already have a system where this already works and I can define as much actions with as much properties as I want. The definitions I have kinda looks like this: {id:101, category:544, onInit:{gold:-75}, onComplete:{energy:75}, time:2000, name:"Apple", locked: false} {id:102, category:544, onInit:{gold:-135}, onComplete:{energy:145}, time:2000, name:"Banana", locked: false} {id:106, category:302, onInit:{energy:-50, power: -25}, onComplete:{gold:100, diamonds:2}, time:10000, name:"Run", locked: false} {id:107, category:302, onInit:{energy:-70, silver: -55}, onComplete:{gold:100}, time:10000, name:"Dance", locked: false} {id:108, category:302, onInit:{energy:-230, power: -355}, onComplete:{gold:70, silver:70}, time:10000, name:"Fitness", locked: false} Now, I would love to add a system where I can lock/unlock the actions using achievement rules. Lets say, if you buy 10 apples, you unlock a new action, like bananas which cost more, and reward more. In the future I maybe want to restrict achievements and actions to levels. I am kinda stuck how to structure this. I have 2 questions: Which patterns are used to define achievements? How/where are they defined? Should it be part of the action, or should it be a separate controller? Is it a good idea to register all completed actions to it? I think I want multiple types of achievement rules, Id love to hear some ideas how to develop it. How do you create/find a good balance, so the user does not get stuck or can cheat by repeat a pattern of actions to get too much rewards. I know there is not a simple answer and i'm lacking of a good game-concept, but I wonder if anyone created such a game and how you dealed and played with it.

• mongoDB Management Studio

  - by Liam McLennan

  This weekend I have been in Sydney at the MS Web Camp, learning about web application development. At the end of the first day we came up with application ideas and pitched them. My idea was to build a web management application for mongoDB. mongoDB I pitched my idea, put down the microphone, and then someone asked, “what’s mongo?”. Good question. MongoDB is a document database that stores JSON style documents. This is a JSON document for a tweet from twitter: db.tweets.find()[0] { "_id" : ObjectId("4bfe4946cfbfb01420000001"), "created_at" : "Thu, 27 May 2010 10:25:46 +0000", "profile_image_url" : "http://a3.twimg.com/profile_images/600304197/Snapshot_2009-07-26_13-12-43_normal.jpg", "from_user" : "drearyclocks", "text" : "Does anyone know who has better coverage, Optus or Vodafone? Telstra is still too expensive.", "to_user_id" : null, "metadata" : { "result_type" : "recent" }, "id" : { "floatApprox" : 14825648892 }, "geo" : null, "from_user_id" : 6825770, "search_term" : "telstra", "iso_language_code" : "en", "source" : "&lt;a href=&quot;http://www.tweetdeck.com&quot; rel=&quot;nofollow&quot;&gt;TweetDeck&lt;/a&gt;" } A mongodb server can have many databases, each database has many collections (instead of tables) and a collection has many documents (instead of rows). Development Day 2 of the Sydney MS Web Camp was allocated to building our applications. First thing in the morning I identified the stories that I wanted to implement: Scenario: View databases Scenario: View Collections in a database Scenario: View Documents in a Collection Scenario: Delete a Collection Scenario: Delete a Database Scenario: Delete Documents Over the course of the day the team (3.5 developers) implemented all of the planned stories (except ‘delete a database’) and also implemented the following: Scenario: Create Database Scenario: Create Collection Lessons Learned I’m new to MongoDB and in the past I have only accessed it from Ruby (for my hare-brained scheme). When it came to implementing our MongoDB management studio we discovered that their is no official MongoDB driver for .NET. We chose to use NoRM, honestly just because it was the only one I had heard of. NoRM was a challenge. I think it is a fine library but it is focused on mapping strongly typed objects to MongoDB. For our application we had no prior knowledge of the types that would be in the MongoDB database so NoRM was probably a poor choice. Here are some screens (click to enlarge):

• Using multiple diagrams per model in Entity Framework 5.0

  - by nikolaosk

  I have downloaded .Net framework 4.5 and Visual Studio 2012 since it was released to MSDN subscribers on the 15th of August.For people that do not know about that yet please have a look at Jason Zander's excellent blog post .Since then I have been investigating the many new features that have been introduced in this release.In this post I will be looking into theIn order to follow along this post you must have Visual Studio 2012 and .Net Framework 4.5 installed in your machine.Download and install VS 20120 using this link.My machine runs on Windows 8 and Visual Studio 2012 works just fine. I have also installed in my machine SQL Server 2012 developer edition. I have also downloaded and installed AdventureWorksLT2012 database.You can download this database from the codeplex website.   Before I start showcasing the demo I want to say that I strongly believe that Entity Framework is maturing really fast and now at version 5.0 can be used as your data access layer in all your .Net projects.I have posted extensively about Entity Framework in my blog.Please find all the EF related posts here. In this demo I will show you how to split an entity model into multiple diagrams using the new enhanced EF designer. We will not build an application in this demo.Sometimes our model can become too large to edit or view.In earlier versions we could only have one diagram per EDMX file.In EF 5.0 we can split the model into more diagrams.1) Launch VS 2012. Express edition will work fine.2) Create a New Project. From the available templates choose a Web Forms application  3) Add a new item in your project, an ADO.Net Entity Data Model. I have named it AdventureWorksLT.edmx.Then we will create the model from the database and click Next.Create a new connection by specifying the SQL Server instance and the database name and click OK.Then click Next in the wizard.In the next screen of the wizard select all the tables from the database and hit Finish.4) It will take a while for our .edmx diagram to be created. When I select an Entity (e.g Customer) from my diagram and right click on it,a new option appears "Move to new Diagram".Make sure you have the Model Browser window open.Have a look at the picture below 5) When we do that a new diagram is created and our new Entity is moved there.Have a look at the picture below  6) We can also right-click and include the related entities. Have a look at the picture below. 7) When we do that the related entities are copied to the new diagram.Have a look at the picture below  8) Now we can cut (CTRL+X) the entities from Diagram2 and paste them back to Diagram1.9) Finally another great enhancement of the EF 5.0 designer is that you can change colors in the various entities that make up the model.Select the entities you want to change color, then in the Properties window choose the color of your choice. Have a look at the picture below. To recap we have demonstrated how to split your entity model in multiple diagrams which comes handy in EF models that have a large number of entities in them Hope it helps!!!!

• Business Choices and Evony

  - by Robert May

  Recently, I’ve been playing a game called Evony, and I finally decided to quit the game and thought I should warn others who might be tempted.  I also find a lot of insight with this game as an example.  A few of the companies that I’ve worked with or worked for have been like this and they are NOT good places to be. Evony is a joke designed to milk as much money out of people as possible.  As a professional software developer who mentors teams on how to build better software, here's what I see: They obviously offshore all development and have little oversight over that offshore development, and they probably have a small team at that.  Evidenced by the poor grammar throughout the game. They're seeking to maximize revenue and pushing to do as little development as possible, which would mean a small team. They're horribly understaffed in the customer support department as evidenced by never replying to this forum and never responding to bug reports or help requests (I've had one open with no response AT ALL for over a month . . .) They have way inadequate testing, no CI, and probably no automated unit tests.  You can see this by the poor grammar throughout the game and the type of bugs that show up. They aren't following a formal development process (no Agile, Waterfall, or anything else) as evidenced by their lack of predictable release cycle and lack of visibility. I'm guessing that the internal code base is terrible, otherwise, there wouldn't be an "Age II" that had nothing more than a new visual interface and a few rule tweaks.  This is also evidenced by the itty bitty scope of bug fixes and their inability to really fix bugs. Their Architect sucks.  Really, 42k user is all you can handle on a single server?  Could you REALLY not come up with a better way to scale to handle users?  They've built isolated worlds, instead of a single continuous world. Back to milking people for money--to really progress, you have to spend money. All of this adds up to knowing, deliberate actions on the part of management.  They CHOOSE to do this (like AOL choosing to send more discs instead of improve quality). So, what can we learn? This game will never really improve, since the bosses don't care, they're only in it for the money. The game will never have good support.  Again, the owners don't care. Giving them money only perpetuates this scam (and yes, I've given them money, way too much money. :() They don't care if you quit.  There's a new sucker born every day. Don't EVER go to work for them.  I've worked both with and for people like this and the culture is NEVER good. Ah well. Technorati Tags: Evony

• Visual WebGui's XAML based programming for web developers

  - by Webgui

  While ASP.NET provides an event base approach it is completely dismissed when working with AJAX and the richness of the server is lost and replaced with JavaScript programming and couple with a very high security risk. Visual WebGui reinstates the power of the server to AJAX development and provides a statefull yet scalable, server centric architecture that provides the benefits and user productivity of AJAX with the security and developer productivity we had before AJAX stormed into our lives. "When I first came up with the concept of Visual WebGui , I was frustrated by the fragile and complex nature of developing web applications. The contrast in productivity between working in a fully OOP compiled environment vs. scripting even today, with JQuery, Dojo and such, is still huge. Even today the greatest sponsor of JavaScript programming, Google, is offering a framework to avoid JavaScript using Java that compiles to JavaScript (GWT). So I decided to find a way to abstract the complexity or rather delegate the complex job to enable developers to concentrate on the “What” instead of the “How” and embraced the Form based approach," said Guy Peled the inventor of Visual WebGui. Although traditional OOP development still rules the enterprise, the differences between web sites and web applications have blurred and so did the differences between classic developers and web developers. As a result, we now see declarative languages in desktop / backend development environments (WPF / WF) and we see OOP, gaining more and more power in web development (ASP.NET MVC / ASP.NET DOM). However, what has not changed is enterprise need for security, development ROI, reach, highly responsive and interactive UIs and scalability. The advantages that declarative languages and 'on demand' compilation provide over classic development are mostly the flexibility and a more readable initialize component it offers which is what Gizmox is aspiring to do by replacing the designer initialize component with XAML code. The code in this new project template will be compiled on demand using the build provider mechanism ASP.NET has. This means that the performance hit is only on the first request and after that the performance is the same as a prebuilt solution. This will allow the flexibility of a dynamically updated sites and the power of fully blown enterprise applications over web. You can also use prebuilt features available in ASP.NET to enjoy both worlds in production. VWG XAML implementation (VWG Sites) will be the first truly compliable XAML implementation as Microsoft implemented Silverlight and WPF as a runtime markup interpretation opposed to the ASP.NET markup implementation which is compiled to CLR code once. We have chosen to implement the VWG Sites parser as a different way to create CLR code that provides greater performance over the reflection alternative. VWG Sites will also be the first server side XAML UI engine which, while giving the power of XAML, it will not require any plug-ins or installations on the client side. Short demo video of VWG Sites markup. There is also a live sample available here.

• Common SOA Problems by C2B2

  - by JuergenKress

  SOA stands for Service Oriented Architecture and has only really come together as a concrete approach in the last 15 years or so, although the concepts involved have been around for longer. Oracle SOA Suite is based around the Service Component Architecture (SCA) devised by the Open SOA collaboration of companies including Oracle and IBM. SCA, as used in SOA suite, is designed as a way to crystallise the concepts of SOA into a standard which ensures that SOA principles like the separation of application and business logic are maintained. Orchestration or Integration? A common thing to see with many people who are beginning to either build a new SOA based infrastructure, or move an old system to be service oriented, is confusion in the purpose of SOA technologies like BPEL and enterprise service buses. For a lot of problems, orchestration tools like BPEL or integration tools like an ESB will both do the job and achieve the right objectives; however it’s important to remember that, although a hammer can be used to drive a screw into wood, that doesn’t mean it’s the best way to do it. Service Integration is the act of connecting components together at a low level, which usually results in a single external endpoint for you to expose to your customers or other teams within your organisation – a simple product ordering system, for example, might integrate a stock checking service and a payment processing service. Process Orchestration, however, is generally a higher level approach whereby the (often externally exposed) service endpoints are brought together to track an end-to-end business process. This might include the earlier example of a product ordering service and couple it with a business rules service and human task to handle edge-cases. A good (but not exhaustive) rule-of-thumb is that integrations performed by an ESB will usually be real-time, whereas process orchestration in a SOA composite might comprise processes which take a certain amount of time to complete, or have to wait pending manual intervention. BPEL vs BPMN For some, with pre-existing SOA or business process projects, this decision is effectively already made. For those embarking on new projects it’s certainly an important consideration for those using Oracle SOA software since, due to the components included in SOA Suite and BPM Suite, the choice of which to buy is determined by what they offer. Oracle SOA suite has no BPMN engine, whereas BPM suite has both a BPMN and a BPEL engine. SOA suite has the ESB component “Mediator”, whereas BPM suite has none. Decisions must be made, therefore, on whether just one or both process modelling languages are to be used. The wrong decision could be costly further down the line. Design for performance: Read the complete article here.

• Architecture for a template-building, WYSIWIG application

  - by Sam Selikoff

  I'm building a WYSIWYG designer in Ember.js. The designer will allow users to create campaigns - think MailChimp. To build a campaign, users will choose an existing template. The template will have a defined layout. The user will then be taken to the designer, where he will be able to edit the text and style, and additionally change some layout options. I've been thinking about how best to go about structuring this app, and there are a few hurdles. Specifically, the output of the campaign will be dynamic: eventually, it will be published somewhere, and when the consumers (not my users, but the people clicking on the campaign that my user created) visit the campaign, certain pieces of data will change, depending on the type of consumer viewing the campaign. That means the ultimate output of the designer will be a dynamic site. The data that is dynamic for this site - the end product - will not be manipulated by the user in the designer. However, the data that will be manipulated by the user in the designer are things like copy, styles, layout options, etc. I'll call the first set of variables server-side data, and the second client-side data. It seems, then, that the process will go something like this: I'll need to create templates for this designer that have two dynamic segments. For instance, the server-side data could be Liquid expressions, and the client-side data Handlebars expressions. When the user creates a campaign, I would compile the template on the back end using some dummy data for the server-side variables, and serve up a handlebars template to the Ember app. The user would then edit the template, and the Ember app would save all his edits to the JS variables that were powering the template. This way he'd be able to preview the template. When he saves, he'll send back the selected template, along with all the data and options he's made. When it comes time to publish, the back-end system will have to do two things: compile the template with Handlebars using the campaign data, and then compile the template with Liquid using the server-side data Is my thinking roughly accurate about this, or is there a simpler way?

• Do you know about the Visual Studio 2010 Database Projects Guidance?

  - by Martin Hinshelwood

  Early on in the Team System (now Visual Studio ALM) cycle a new product surfaced within Team System that was affectionately called “Data Dude”, but had the more formal name of “Visual Studio 2005 Team Edition for Database Professionals”. The purpose of this product was to try and make the database a “first class citizen” in the development world. Those that started using Visual Studio 2005 Team Edition for Database Professionals (Data Dude) loved it, but everyone else did not get it. The capabilities were a little patchy, but the one thing it did bring to the party was the ability to put your database schema under source control. This was revolutionary as previously your DBA sat as far away from the team as possible, and usually in a dark cupboard, now they could partake of all the goodness of Version Control, Work Item Tracking and automated builds. The problem was that the understanding required to manage these projects was very different to that needed previously. Then the Visual Studio ALM Rangers got a hold of it…and produced some of the best guidance available. Figure: Download the guidance from http://vsdatabaseguide.codeplex.com/ This guidance discusses scenarios and approaches of using the Database Projects in Visual Studio 2010 to help you use the tools more effectively and maximize their value to your organization This guidance is focused on these five areas: Solution and Project Management Source Code Control and Configuration Management Integrating External Changes with the Project System Build and Deployment Automation with Visual Studio Database Projects Database Testing and Deployment Verification Each of these areas has common guidance, usage scenarios, hands on labs, and lessons learned from real world engagements and the community discussions.   The guidance is broken down into three packages: Guidance documentation Hands-on-lab (HOL) documentation note: The documentation is available in XPS-only format packages or complete XPS,PDF,DOCX format packages HOL Package If you need assistance and no one else can help, then you may need to call the Visual Studio ALM Rangers. The Visual Studio ALM Rangers have the mission to provide out of band solutions for missing features or guidance. They are supported by Microsoft Product Group, Microsoft Consulting Services, Microsoft Most Valued Professionals (MVPs) and technical specialists from technology communities around the globe, giving you a real-world view from the field, where the technology has been tested and used.

• Power Distribution amongst connected nodes

  - by Perky

  In my game the map is represented by connected nodes, each node has a number of connected nodes. The nodes represent a system in which players can build structures and move units about. If you're familiar with Sins of a Solar Empire the game map is very similar. I want each node to be able to produce power and share it with all connected nodes. For example if A, B, C & D are all connected and produce 100 power units, then each system should have 400 power units available. If node B builds a structure that consumes 100 power units then A, B, C & D should then have 300 power units available. I've been working on this system all day and haven't been able to get it working quite the way I want. My current implementation is to first recurse through each nodes's connected node adding up the power, I keep a list of closed nodes so it doesn't loop, it's quite similar to A* actually. Pseudo code: All nodes start with the properties node.power = 0 node.basePower = 100 // could be different for each node. node.initialPower = node.basePower - function propagatePower( node, initialPower, closedNodes ) node.power += initialPower add( closedNodes, node ) connectedNodes = connected_nodes_except_from( closedNodes ) foreach node in connectedNodes do propagatePower( node, initialPower, closedNodes ) end end After this I iterate through all power consumers. foreach consumer in consumers do node = consumer.parentNode if node.power >= consumer.powerConsumption then consumer.powerConsumed += consumer.powerConsumption node.producedPower -= consumer.powerConsumption end end Then I adjust the initial power for the next propagation cycle. foreach node in nodes do node.initialPower = node.basePower - node.producedPower node.displayPower = node.power // for rendering the power. node.power = 0 end This seemed to work at first but then I came into a problem. Say two nodes A & B produce 100Pu each, it's shared so both A & B have 200Pu. I then make two structures that consume 80Pu each on A (160Pu). Then the nodes power is adjusted to basePower - producedPower (100-160 = -60). Nodes are propagated, both nodes now have 40Pu (A: -60 + B: 100 = 40). Which is correct because they started with 200Pu - 160Pu = 40Pu. However now node.power >= consumer.powerConsumption is false. Whats worse is it's false for any structure that uses more that 40Pu, so the whole system goes down. I could deduct from consumer.powerConsumption but what do I do if power is reduced elsewhere? I don't have the correct data to perform the necessary checks. It's late so I'm probably not thinking straight but I thought to ask on here to see if anyone has any other implementations, better or worse I'd be interested to know.

• Career Change Need Advice: Professional Web Developer

  - by bikedorkseattle

  I'm hoping to get some advice here on the steps I should take to make a career change into professional web development. I've been working in cancer research the last 14 years and I need a change. The job market is terrible, the pay is worse, and despite what one would think the atmosphere is generally un-collegial, even in your own group. Venture funding never returned after the dot com burst and with 3 to 5 wars our country is now in, NIH funding is only going to get worse. I know things are not going to get better for my field, sadly, and I know I need to move on. For probably just as long I have fiddled around with web development, I even run a fairly popular site with close to 1 million/month pageviews that pulls a decent income, but not stable enough to live off of right now. My skills are ok for being self taught. I enjoy the fast paced nature of the web and the tools the community creates and how eager people are to help and share knowledge; it's what science should be. I have been trying to find an entry level developer job doing standard HTML/CSS/PHP/MySQL/JS/jQuery type work. A good 50%+ of the jobs want someone with a CS degree, and most want 5 years experience. Having no professional experience and no formal education, I know I'm at a huge disadvantage. I am now considering my options on how to move forward professionally. The way I see it I have basically 3 options. Build up my portfolio of work as much as I can and continue to learn as much as I can on my own. Try to contribute on some open source project when time allows. Network like crazy and go to meetups. Be confident and pray a lot in private. OR While doing above, do some certification programs in PHP and Java, possibly others. Get a Zend Certification. OR Spend a few years getting a CS degree while doing 1. I've already done the work fulltime go to school thing and it doesn't excite me one bit. I didn't have the greatest college experience and am not too eager to return, but I have a family to feed. Is the degree really necessary or is it more of a right of passage type thing in most instances? I appreciate everyones input. Thanks for taking the time to respond.

• Play or Lift: which one is more explicit?

  - by Andrea

  I am going to investigate web development with Scala, and the choice is between learning Lift or Play: probably I will not have enough time to try both, at least at first. Now, many comparisons between the two are available on the internet, but I would like to know how do they compare with respect to being explicit and involving less magic. Let me explain what I mean by example. I have used, to various degrees, CakePHP, symfony2, Django and Grails. I feel a very clear distinction between Django and symfony2, which are very explicit about what you are doing, and Grails and CakePHP, which try to do their best to guess what you are trying to achieve and often feel "magical". Let me give some examples comparing Django and Grails. In Django, views are functions that take a request as input and return a response. You can instantiate explicitly an instance of HttpResponse and populate its body with a string, or you can use shortcut functions to leverage the template system. In any case the return value from your view always has the same type. In contrast, the render method from Grails is highly polymorphic. You can throw a context at it and it will try to render a template which is found by convention using that context. Or you can pass it a pair of a template path and a context and that will work too. Or a string. Or XML. Grails tries hard to make sense of whatever you return from your controller. In the Django ORM, each model class has a static attribute representing the manager for that class. That manager exposes a fluent interface to build querysets. In Grails, you can have a similar functionality by composing detached criteria. Still, the most common way to query objects seems to be the use of runtime-generated methods like FindUserByEmailNotNull or FindPostByDateGreaterThan. I will not go further, but my point is that in Django-like frameworks you have control over the whole flow of the request/response process, while in Grails-like ones I feel I only have to feel the blanks and the framework will manage the rest of the flow for me. This is not to criticize Grails or CakePHP; which type you prefer is mainly a matter of preference. In fact, I happen to like some aspects of Grails, but I feel more comfortable with a framework which does less for me. Back to the point of the question: which one among Play and Lift is more explicit about what you do and which one tries to simplify more what you have to do with a layer of "magic"?

• Do I need to create my own or use a commercial server for the features and matchmaking options I want my game to support?

  - by baptzmoffire

  So I'm developing an indie turn-based game for iOS and, in coding up a Game Center matchmaking class, I'm starting to question whether Game Center is even the best choice for what I want this game to do. I need to figure out whether I need to create my own server, invest in a preexisting client or server service, or if I even need to use a server at all. If I do need to use a ready-made service other than Game Center, which server would accomodate my game's needs best? I have limited resources and funds. Here is the list of features I want my game to support, ideally: Turn-based gameplay (a la "with Friends" and "with Buddies" games) Smart matchmaking (matching users up with other players of comparable skill/achievements) Random matchmaking Facebook matchmaking Specific username matchmaking Contact list matchmaking A way to select what "type" of match you want to challenge an opponent to. (In random, smart, and Facebook matchmaking, there will be different "wagers" the player can make. [e.g. "I wanna play a random opponent for 1000 points. Now, I wanna play my Facebook buddy for 1,000,000 points."] There will be a predetermined range of amounts you can play for. It won't be customizable.) Buddies list capability (Game-buddies, as opposed to contacts and Facebook) A higher concurrent game cap than Game Center offers (which I still can't really find a straight answer on) Scalability (it should support 2 or 20,000,000 players) Objective-C compatibility Flexibility (for all the stuff I haven't thought of yet) Am I dreaming, here? Is there even a service that can handle all of these features? Do I need to invest months in learning a networking language to build my own? If so, how much would I need to spend on hardware? I've been looking around all morning and, so far, the only seemingly viable option is SmartFox. Under "Everything and the kitchen sink" section here, it says they support "virtual world with Zones, Rooms and RoomGroups, create complex game challenges, send invitations, manage buddy lists, create custom permission profiles, oversee the security aspects and tons more." http://www.smartfoxserver.com/overview/platform Is there an option that Im just overlooking? Thanks for any help anyone can provide. Sorry for the long poast. One last question: Does anyone know which server Dice with Buddies uses? I was experimenting with how many concurrent games I could get going and my ADHD kicked in at about 80 games. 80 concurrent games would be great for my game, but again, I need the other features I mentioned too. Thanks again.

• TechEd 2012: Windows 8 And Metro

  - by Tim Murphy

  Windows 8 is here (or at least very close) and that was the main feature of this morning’s key note.  Antoine LeBlond started off by apologizing to the IT professionals since he planned on showing code.  I’m not sure if IT Pros are that easily confused or why you would need such a disclaimer.  Developers do real work, IT Pros just play with toys (just kidding). The highlights of the Windows 8 keynote for me started with some of the UI design elements that I had not seen when I was shown one of the Build tablets.  Specifically I liked the AppBar features that we have become used to with Windows Phone and some of the gesture features.  Even though they have been available on other platforms before I think Microsoft really got them right. Two other great features of Windows 8 that they demonstrated were the Hyper-V capabilities and the ability to run Windows 8 anywhere from a USB key.  My jaw dropped through the floor seeing a feature rich OS boot off of a thumb drive. WOW!  I also can’t wait to get rid of dual booting just to run Hyper-V images when developing. The morning continued with a session on Metro XAML development with Tim Heuer.  While included a lot of great XAML Metro demos, I was pleasantly surprised by some of the things I found out about Visual Studio 2012.  Finding out that Blend is now integrated with VS2012 was a nice addition after working with them as separate applications was an encouraging start. Moving on to Metro he introduced the nugget that WinRT is Async everywhere.  How deep this model goes will be an interesting thing to find out as I learn more about developing for the platform.  Thankfully he followed that up with a couple of new keywords, await and async, that eliminates a lot of plumbing that has been required in the past for asynchronous transactions. Tim also related that since the Metro framework is relatively small and most apps will use a significant amount of it the entire surface is referenced by default.  This is a contrast to adding namespace and assemblies one after another as we normally do. This was such a power packed session that I can’t detail it all here so here is the teaser list. New icons in VS2012 for extension methods Emulator/simulator testing features for gestures Portable class libraries XAML no longer managed code And so much more …   del.icio.us Tags: Windows 8,Metro,Tim Heuer,XAML,Widows Phone,Hyper-V,Antoine LeBlond,TechEd,TechEd 2012,Visual Studio 2012,Visual Studio

• Is Cygwin or Windows Command Prompt preferable for getting a consistent terminal experience for development?

  - by Paul Hazen

  The question: Which is better, installing cygwin or one of its cousins on all my windows machines to have a consistent terminal experience across all my development machines, or becoming well trained in the skill of mentally switching from linux terminal to windows command prompt? Systems I use: OSX Lion on a Macbook Air Windows 8 on a desktop Windows 7 on the same desktop Fedora 16 on the same desktop What I'm trying to accomplish Configure an entirely consistent (or consistent enough) terminal experience across all my machines. "enough" in this context is clearly subjective. Please be clear in your answer why the configuration you suggest is consistent enough. One more thing to keep in mind: While I do write a lot of code intended to run on Windows (actually code that runs on Windows Phone which necessitates a windows machine), I also write a lot of Java code, and prefer to do so in vim. I test a local repo in Java on my windows machine, and push to another test machine running ubuntu later in the development stage. When I push to the ubuntu machine, I'm exclusively in terminal, since I'm accessing it via SSH. Summary, with more accurate question: Is there a good way to accomplish what I'm trying to do, or is it better to get accustomed to remembering different commands based on the system I'm on? Which (if either) is considered "best practice" by the development community? Alternatively, for a consistent development experience, would it be better to write all my code SSHed into another machine, and move things to windows for compile / build only when I needed to? That seems like too much work... but could be a solution. Update: While there are insightful responses below, I have yet to hear an answer that talks about why any given solution is superior. Cygwin/GnuWin32 is certainly a way to accomplish a similar experience on all platforms, but since I'm just learning all things command line, I don't want to set myself up to do a lot of relearning/unlearning in the future. Cygwin/GnuWin32 has its peculiarities I would imagine, and being aware of how that set up works on Windows is a learning curve. Additionally, using Cygwin/GnuWin32 robs me of learning the benefits of PowerShell. As a newcomer to working in a command line, which path should I choose to minimize having to relearn/unlearn things in the future? or as my first paragraph poses: [is it better to use Cygwin] ...or [become] well trained in the skill of mentally switching from linux terminal to windows command prompt?

• Configuring Full-Text Search for pdf and docx files

  - by Lukasz Kurylo

  I think in may I was creating a little filters module based on Full Text-Search. I have configured my dev machine, the same for two testing servers – in our company for internal testing before we deployed it to client, and then on the testing client server. Until last week this build  was still on the testing server and finally we got feedback that we can deploy it on the production one. I only say that, I lost half a day because I had not correctly remembered what I was doing to configure the FTS on the previous servers and I had no notes for that. I foolishly believed in my memory. Lesson learned.   For future reference a bunch of steps to configure the FTS for searching in *.pdf and *.docx files (and by the way in other Office files like *.xlsx).   1. From the page (link) download and install the *.pdf IFilter for FTS. 2. To the PATH global system variable add path to the catalog, where you installed the plugin. Default for this version is: C:\Program Files\Adobe\Adobe PDF iFilter 9 for 64-bit platforms\bin 3. From the page (link) download a FilterPackx64.exe and install it. 4. Now from SSMS execute the following procedures: -sp_fulltext_service 'load_os_resources',1 -sp_fulltext_service 'verify_signature', 0 5. Restart the server 6.
