• Distinguishing between UI command & domain commands

  - by SonOfPirate

  I am building a WPF client application using the MVVM pattern that provides an interface on top of an existing set of business logic residing in a library which is shared with other applications. The business library followed a domain-driven architecture using CQRS to separate the read and write models (no event sourcing). The combination of technologies and patterns has brought up an interesting conundrum: The MVVM pattern uses the command pattern for handling user-interaction with the view models. .NET provides an ICommand interface which is implemented by most MVVM frameworks, like MVVM Light's RelayCommand and Prism's DelegateCommand. For example, the view model would expose a number of command objects as properties that are bound to the UI and respond when the user performs actions like clicking buttons. Many implementations of the CQRS use the command pattern to isolate and encapsulate individual behaviors. In my business library, we have implemented the write model as command / command-handler pairs. As such, when we want to do some work, such as create a new order, we 'issue' a command (CreateOrderCommand) which is routed to the command-handler responsible for executing the command. This is great, clearly explained in many sources and I am good with it. However, take this scenario: I have a ToolbarViewModel which exposes a CreateNewOrderCommand property. This ICommand object is bound to a button in the UI. When clicked, the UI command creates and issues a new CreateOrderCommand object to the domain which is handled by the CreateOrderCommandHandler. This is difficult to explain to other developers and I am finding myself getting tongue-tied because everything is a command. I'm sure I'm not the first developer to have patterns overlap like this where the naming/terminology also overlap. How have you approached distinguishing your commands used in the UI from those used in the domain? (Edit: I should mention that the business library is UI-agnostic, i.e. no UI technology-specific code exists, or will exists, in this library.)

• Run database checks but omit large tables or filegroups - New option in Ola Hallengren's Scripts

  - by Greg Low

  One of the things I've always wanted in DBCC CHECKDB is the option to omit particular tables from the check. The situation that I often see is that companies with large databases often have only one or two very large tables. They want to run a DBCC CHECKDB on the database to check everything except those couple of tables due to time constraints. I posted a request on the Connect site about time some time ago: https://connect.microsoft.com/SQLServer/feedback/details/611164/dbcc-checkdb-omit-tables-option The workaround from the product team was that you could script out the checks that you did want to carry out, rather than omitting the ones that you didn't. I didn't overly like this as a workaround as clients often had a very large number of objects that they did want to check and only one or two that they didn't. I've always been impressed with the work that our buddy Ola Hallengren has done on his maintenance scripts. He pinged me recently about my old Connect item and said he was going to implement something similar. The good news is that it's available now. Here are some examples he provided of the newly-supported syntax: EXECUTE dbo.DatabaseIntegrityCheck @Databases = 'AdventureWorks', @CheckCommands = 'CHECKDB' EXECUTE dbo.DatabaseIntegrityCheck @Databases = 'AdventureWorks', @CheckCommands = 'CHECKALLOC,CHECKTABLE,CHECKCATALOG', @Objects = 'AdventureWorks.Person.Address' EXECUTE dbo.DatabaseIntegrityCheck @Databases = 'AdventureWorks', @CheckCommands = 'CHECKALLOC,CHECKTABLE,CHECKCATALOG', @Objects = 'ALL_OBJECTS,-AdventureWorks.Person.Address' EXECUTE dbo.DatabaseIntegrityCheck @Databases = 'AdventureWorks', @CheckCommands = 'CHECKFILEGROUP,CHECKCATALOG', @FileGroups = 'AdventureWorks.PRIMARY' EXECUTE dbo.DatabaseIntegrityCheck @Databases = 'AdventureWorks', @CheckCommands = 'CHECKFILEGROUP,CHECKCATALOG', @FileGroups = 'ALL_FILEGROUPS,-AdventureWorks.PRIMARY' Note the syntax to omit an object from the list of objects and the option to omit one filegroup. Nice! Thanks Ola! You'll find details here: http://ola.hallengren.com/

  Die Channel-Expertin spricht im Interview mit der IT-Business über Engineered Systems, neue Wege im Partner-Geschäft und die Konsolidierung der IT-Branche Das Produktspektrum von Oracle wird, vor allem seit der massiven Ausweitung in Richtung Hardware, immer breiter. Umso notwendiger werden Spezialisierungen für die Partner. Im Exklusivinteriew mit der IT-Business beantwortet Silvia Kaske, Senior Director Channel Sales & Alliances North bei Oracle, unter anderem die Frage „Wie man im Oracle Universum Geld verdient“. Neben unserem Blog-Kernthema, den Spezialisierungen, spricht Kaske auch darüber, wie die neue Projektdatenbank hilft, im Channel Konflikte zu vermeiden. Das lesenswerte Interview finden Sie als Titelstory in der IT-Business Nr. 17/2012 und auf IT-Business.de. Hier ein Abstract, was Sie dort erwartet: Zu den Engineered Systems, einem zentralen Thema für Oracle, äußert sich Kaske gleich zu Beginn. Sie betont, dass Oracle zwar optimal abgestimmte Gesamtpakete wie die Oracle SOA Suite anbietet, jedoch keine Entwicklung hin zu in sich abgeschlossenen Systemen möchte. Oracle Lösungen bleiben offen für die Kombination mit Produkten anderer Anbieter. Optimized Solutions seien vor allem dafür da, „die interne Komplexität in Unternehmen zu minimieren, um damit Kosten für den Betrieb der bestehenden Systeme zu senken.“ Das ausgefeilte System der Spezialisierungen hat ein klares Ziel: „Wir wollen Partner, die genau wissen, was sie tun, und die Endkunden bestmöglich beraten und betreuen“, sagt Kaske. Das erfordert ein hohes Wissen in einer oder mehreren Branchen oder Produktsegmenten – niemand erwartet schließlich von einem Partner, Experte für alle 9.000 Einzelprodukte zu sein. Dafür stehen derzeit über 100 zertifizierte Spezialisierungen zur Wahl. Das Programm OPN Specialised steht seit nunmehr zwei Jahren für die Entwicklung hin zu höheren Zertifizierungsanforderungen und damit zu noch kompetenteren Partnern. Zudem fördert Oracle die Kooperation verschieden spezialisierter Partner untereinander, Stichwort „Enablement 2.0“.

• What kind of physics to choose for our arcade 3D MMO?

  - by Nick

  We're creating an action MMO using Three.js (WebGL) with an arcadish feel, and implementing physics for it has been a pain in the butt. Our game has a terrain where the character will walk on, and in the future 3D objects (a house, a tree, etc) that will have collisions. In terms of complexity, the physics engine should be like World of Warcraft. We don't need friction, bouncing behaviour or anything more complex like joints, etc. Just gravity. I have managed to implement terrain physics so far by casting a ray downwards, but it does not take into account possible 3D objects. Note that these 3D objects need to have convex collisions, so our artists create a 3D house and the player can walk inside but can't walk through the walls. How do I implement proper collision detection with 3D objects like in World of Warcraft? Do I need an advanced physics engine? I read about Physijs which looks cool, but I fear that it may be overkill to implement that for our game. Also, how does WoW do it? Do they have a separate raycasting system for the terrain? Or do they treat the terrain like any other convex mesh? A screenshot of our game so far:

• Concurrency pattern of logger in multithreaded application

  - by Dipan Mehta

  The context: We are working on a multi-threaded (Linux-C) application that follows a pipeline model. Each module has a private thread and encapsulated objects which do processing of data; and each stage has a standard form of exchanging data with next unit. The application is free from memory leak and is threadsafe using locks at the point where they exchange data. Total number of threads is about 15- and each thread can have from 1 to 4 objects. Making about 25 - 30 odd objects which all have some critical logging to do. Most discussion I have seen about different levels as in Log4J and it's other translations. The real big questions is about how the overall logging should really happen? One approach is all local logging does fprintf to stderr. The stderr is redirected to some file. This approach is very bad when logs become too big. If all object instantiate their individual loggers - (about 30-40 of them) there will be too many files. And unlike above, one won't have the idea of true order of events. Timestamping is one possibility - but it is still a mess to collate. If there is a single global logger (singleton) pattern - it indirectly blocks so many threads while one is busy putting up logs. This is unacceptable when processing of the threads are heavy. So what should be the ideal way to structure the logging objects? What are some of the best practices in actual large scale applications? I would also love to learn from some of the real designs of large scale applications to get inspirations from!

• Multiple URL's going to same page - Kosher for Google?

  - by Ashoka15

  I hear conflicting answers from people about this, and I'm a developer by trade, and my SEO knowledge is not what it should be. Here's my situation: I run a website that lists hotels, restaurants, bars, shops, etc for a small Asian beach town. Lots of establishments here are hotels with a restaurant and bar, as well as restaurants that are also bars. As en example, a Mexican restaurant that also functions as a full cocktail bar. I first set it up so each establishment has one page, but can create multiple pages based on their other areas of business. This forces people to create TWO listings under the same name, and most just add the exact same information onto each page, making things redundant. I am re-arranging the database so that a establishment has only ONE listing (one unique page referenced by the unique code '12345ABCDEF') that is accessible from browsing under "Restaurants" and "Bars", and has the URL structures: site.com/dining/mexican/12345ABCDEF/business-name.html site.com/bars/cocktail_bars/12345ABCDEF/business-name.html I could easily simplify the URL to just the unique code and name: site.com/12345ABCDEF/business-name.html But, I found that Google has parsed by URL structure and lists like this on their SERP: Home > Dining > Mexican With each pointing to the default page for homepage, restaurants and Mexican restaurants. If I simplify the URL structure, will I lose these associations? Could Google also be picking up this structure from my breadcrumb trail at the top of the page? What is the best way to set up URL's on these pages so I am not penalized by Google for having identical information on two URL's, while still being able to have places show up as they did with the old system?

• Is there a canonical source supporting "all-surrogates"?

  - by user61852

  Background The "all-PK-must-be-surrogates" approach is not present in Codd's Relational Model or any SQL Standard (ANSI, ISO or other). Canonical books seems to elude this restrictions too. Oracle's own data dictionary scheme uses natural keys in some tables and surrogate keys in other tables. I mention this because these people must know a thing or two about RDBMS design. PPDM (Professional Petroleum Data Management Association) recommend the same canonical books do: Use surrogate keys as primary keys when: There are no natural or business keys Natural or business keys are bad ( change often ) The value of natural or business key is not known at the time of inserting record Multicolumn natural keys ( usually several FK ) exceed three columns, which makes joins too verbose. Also I have not found canonical source that says natural keys need to be immutable. All I find is that they need to be very estable, i.e need to be changed only in very rare ocassions, if ever. I mention PPDM because these people must know a thing or two about RDBMS design too. The origins of the "all-surrogates" approach seems to come from recommendations from some ORM frameworks. It's true that the approach allows for rapid database modeling by not having to do much business analysis, but at the expense of maintainability and readability of the SQL code. Much prevision is made for something that may or may not happen in the future ( the natural PK changed so we will have to use the RDBMS cascade update funtionality ) at the expense of day-to-day task like having to join more tables in every query and having to write code for importing data between databases, an otherwise very strightfoward procedure (due to the need to avoid PK colisions and having to create stage/equivalence tables beforehand ). Other argument is that indexes based on integers are faster, but that has to be supported with benchmarks. Obviously, long, varying varchars are not good for PK. But indexes based on short, fix-length varchar are almost as fast as integers. The questions - Is there any canonical source that supports the "all-PK-must-be-surrogates" approach ? - Has Codd's relational model been superceded by a newer relational model ?

• Software architecture for two similar classes which require different input parameters for the same method

  - by I Like to Code

  I am writing code to simulate a supply chain. The supply chain can be simulated in either an intermediate stocking or a cross-docking configuration. So, I wrote two simulator objects IstockSimulator and XdockSimulator. Since the two objects share certain behaviors (e.g. making shipments, demand arriving), I wrote an abstract simulator object AbstractSimulator which is a parent class of the two simulator objects. The abstract simulator object has a method runSimulation() which takes an input parameter of class SimulationParameters. Up till now, the simulation parameters only contains fields that are common to both simulator objects, such as randomSeed, simulationStartPeriod and simulationEndPeriod. However, I now want to include fields that are specific to the type of simulation that is being run, i.e. an IstockSimulationParameters class for an intermediate stocking simulation, and a XdockSimulationParameters class for a cross-docking simulation. My current idea is take the method runSimulation() out of the AbstractSimulator class, but to put a runSimulation(IstockSimulationParameters) method in the IstockSimulator class, and a runSimulation(XdockSimulationParameters) method in the IstockSimulator class. I am worried however, that this approach will lead to code duplication. What should I do?

• How to combat negative SEO?

  - by Perturbed

  Someone has decided to create a hate blog on a hosted blogging service (wordpress.com) that bashes my company. The blog contains posts that completely flame myself, my service, and contains complete falsehoods about how I run my business. Without going into details, I'm pretty sure the author of this blog is an owner of a competing service (although it is authored completely anonymously). Frankly, I'm not sure if the content would qualify for defamation or not, but I really don't like the idea of spending money on a lawyer to even attempt to prove this. I also have no interest in retorting or even replying to the blog in any sort of way -- I feel this would justify the ludicrous claims that have been posted. Unfortunately, whoever wrote the blog was pretty smart about using key words that people commonly use to search for my service. Because my customer base is relatively small and local, our PageRank is not incredibly high. As a result, when someone Google's our business name, this blog is usually within the top five results (thankfully, it's never above the business' actual website, but it's usually within eyeshot). It's incredibly frustrating to hear from customers who have seen the link (luckily, most of the time they think the author is crazy). Is there anything I can do to combat this? Would it be worthwhile to setup my own hosted wordpress.com branded blog, in an effort to trump this wordpress.com with a blog that is more active of my own? TL;DR: Someone made a hate blog using wordpress.com and is now on the first page of my business' search results. What are my options?

• 3d Picking under reticle

  - by Wolftousen

  i'm currently trying to work out some 3d picking code that I started years ago, but then lost interested the assignment was completed (this part wasn't actually part of the assignment). I am not using the mouse coords for picking, i'm just using the position in 3d space and a ray directly out from there. A small hitch though is that I want to use a cone and not a ray. Here are the variables i'm using: float iReticleSlope = 95/3000; //inverse reticle slope float baseReticle = 1; //radius of the reticle at z = 0 float maxRange = 3000; //max range to target Quaternion orientation; //the cameras orientation Vector3d position; //the cameras position Then I loop through each object in the world: Vector3d transformed; //object position after transformations float d, r; //holder variables for(i = 0; i < objects.length; i++) { transformed = position - objects[i].position; //transform the position relative to camera orientation.multiply(transformed); //orient the object relative to the camera if(transformed.z < 0) { d = sqrt(transformed[0] * transformed[0] + transformed[1] * transformed[1]); r = -transformed[2] * iReticleSlope + objects[i].radius; if(d < r && -transformed[2] - objects[i].radius <= maxRange) { //the object is under the reticle } else { //the object is not under the reticle } } else { //the object is not under the reticle } } Now this all works fine and dandy until the window ratio doesn't match the resolution ratio. Is there any simple way to account for that

• Draw contour around object in Opengl

  - by Maciekp

  I need to draw contour around 2d objects in 3d space. I tried drawing lines around object(+points to fill the gap), but due to line width, some part of it(~50%) was covering object. I tried to use stencil buffer, to eliminate this problem, but I got sth like this(contour is green): http://goo.gl/OI5uc (sorry I can't post images, due to my reputation) You can see(where arrow points), that some parts of line are behind object, and some are above. This changes when I move camera, but always there is some part, that is covering it. Here is code, that I use for drawing object: glColorMask(1,1,1,1); std::list<CObjectOnScene*>::iterator objIter=ptr->objects.begin(),objEnd=ptr->objects.end(); int countStencilBit=1; while(objIter!=objEnd) { glColorMask(1,1,1,1); glStencilFunc(GL_ALWAYS,countStencilBit,countStencilBit); glStencilOp(GL_REPLACE,GL_KEEP,GL_REPLACE ); (*objIter)->DrawYourVertices(); glStencilFunc(GL_NOTEQUAL,countStencilBit,countStencilBit); glStencilOp(GL_KEEP,GL_KEEP,GL_REPLACE); (*objIter)->DrawYourBorder(); ++objIter; ++countStencilBit; } I've tried different settings of stencil buffer, but always I was getting sth like that. Here is question: 1.Am I setting stencil buffer wrong? 2. Are there any other simple ways to create contour on such objects? Thanks in advance.

• Hosted EBS 11i Integration Repository Temporarily Offline

  - by Steven Chan (Oracle Development)

  Most developers know that they can integrate their external applications with the E-Business Suite via the business service interfaces and SOA service endpoints documented in the E-Business Suite's Integration Repository.  This is shipped as part of EBS 12.  Until recently, it was provided as a hosted environment on the Oracle.com domain for EBS 11i. Unfortunately, we identified some standards-related issues in the process of switching from the existing server that hosts the EBS 11i environment to a new one, notably in the area of accessibility. Some of those issues will require coding changes to resolve.  Given our focus on EBS 12.2 right now, it may take some time to prioritize this relative to our other existing commitments. In the meantime, we are required to suspend access to the EBS 11i Integration Repository.  I don't have a firm schedule for getting this back online yet, but you're welcome to monitor or subscribe to this blog. I'll post updates here as soon as soon as they're available.    Related Articles Integration Repository for the E-Business Suite New Whitepaper: Primer on Integrating with EBS 12 with Other Applications

• Graphical Interface and Object Selection/Manipulation

  - by ToriArendt

  I have a project I want to try to implement, but I'm kind of stuck on how to get started. I know there are probably a lot of resources that I can look at, but I'm really just stuck on what to even search for and where to begin. Basically, I have a program written in Java that separates 3D coordinates from a 3D reconstructed model into different objects. I then want to be able to perform a logistic regression on these objects to determine if they are type A or type B. But first, I need to classify a training set of objects as type A or B by hand. I don't know ANYTHING about graphing or user interfaces in Java, so I have been plotting the coordinates of a given object in MATLAB so that I can visualize the object and assign it a type. Now, as I am trying to make this program more "user friendly" I want to create an interface in Java where I can simply graph all the coordinates of the objects from the entire 3D model (on the same graph). I then want to be able to click on the each object and assign it to be either of type A or type B. I hope this description makes sense and someone can point me in the direction of something that will help me. I'm sorry if some of this terminology is off; I'm a bit new to software development. P.S. If anyone also has some tips on implementing logistic regression in Java, I'm sure I'll need them down the road :).

• Why Do Spreadsheets Not Work in an Enterprise Planning Environment ?

  - by Mike.Hallett(at)Oracle-BI&EPM

  “Around 93% of managers gather or analyze information in spreadsheets and 54% spend more time gathering information than analyzing it....”  Find answers in this Whitepaper: some extracts below: “Traditional budgeting and planning is a straight jacketed and hierarchical exercise.... how many businesses have planning and reporting processes that are smart, agile and aligned? The networked economy challenges the fundamentals of business organization, for example, where does the front-office stop and does the back-office start?  Is it still meaningful to plan for customer, channel, or product profitability, or is transaction profitability the only measure that counts? “Although conceptually, the idea of enterprise business planning is relatively straightforward it has proven to be illusive, because of over reliance on spreadsheet-bound processes, a lack of control over data quality/management, limited use of advanced planning tools and the cultural impediments that afflict many planning processes. “In the absence of specialist tools, businesses tend to opt for ‘broad brush’ assumptions in financial plans which merely approximate the more granular assumptions used in operational plans. “Most businesses are familiar with the relationship between risk and reward but in assessing potential opportunities and developing business plans rarely acknowledge risks and probability in a formal way. Get your customer to see how they do against the “Enterprise Business Planning Checklist”: get them to read the Whitepaper.
