• Engineering as a Service

  - by jgelhaus

  Oracle Exadata Database Machine is known for great compute performance, and over the past few years, it has also become known as a great platform for any type of Oracle Database workload, from data warehousing to online transaction processing (OLTP). But now organizations are turning to Oracle Exadata for business efficiencies and private cloud solutions—for consolidation and database as a service (DBaaS). University of Minnesota For an inside look at how DBaaS is working in the real world, it’s worth checking into the University of Minnesota’s database hotel.  With more than 50,000 students, the University of Minnesota in Minneapolis is one of the largest universities in the United States. The university’s centralized IT group not only has to support all those students but also must provide support and services to more than 40 departments and colleges within the university. They have two Exadata Database Machine X2-2 half-rack systems from Oracle, with four database nodes each and roughly 30 terabytes of usable disk space for each of the Oracle Exadata systems. The university is using Oracle Real Application Clusters (Oracle RAC) for high availability and the Data Guard feature of Oracle Database, Enterprise Edition, for disaster recovery capabilities. The deployment has been live in production since May 2011. Overhead Door When it comes to overhead, revolving, sliding, or other specialty residential and commercial doors, Overhead Door is the worldwide leader. But when they needed to open doors with their customers through a better, faster, and more agile IT infrastructure, Overhead Door turned to Oracle and Oracle Exadata. Oracle Exadata Database Machine plays an important part in Overhead Door’s IT and business strategy. The organization has two Exadata Database Machine X2-2s deployed, one in production and one in development and testing Read the full Oracle Magazine article Engineering as a Service

• Purpose of "new" keyword

  - by Channel72

  The new keyword in languages like Java, Javascript, and C# creates a new instance of a class. This syntax seems to have been inherited from C++, where new is used specifically to allocate a new instance of a class on the heap, and return a pointer to the new instance. In C++, this is not the only way to construct an object. You can also construct an object on the stack, without using new - and in fact, this way of constructing objects is much more common in C++. So, coming from a C++ background, the new keyword in languages like Java, Javascript, and C# seemed natural and obvious to me. Then I started to learn Python, which doesn't have the new keyword. In Python, an instance is constructed simply by calling the constructor, like: f = Foo() At first, this seemed a bit off to me, until it occurred to me that there's no reason for Python to have new, because everything is an object so there's no need to disambiguate between various constructor syntaxes. But then I thought - what's really the point of new in Java? Why should we say Object o = new Object();? Why not just Object o = Object();? In C++ there's definitely a need for new, since we need to distinguish between allocating on the heap and allocating on the stack, but in Java all objects are constructed on the heap, so why even have the new keyword? The same question could be asked for Javascript. In C#, which I'm much less familiar with, I think new may have some purpose in terms of distinguishing between object types and value types, but I'm not sure. Regardless, it seems to me that many languages which came after C++ simply "inherited" the new keyword - without really needing it. It's almost like a vestigial keyword. We don't seem to need it for any reason, and yet it's there. Question: Am I correct about this? Or is there some compelling reason that new needs to be in C++-inspired memory-managed languages like Java, Javascript and C#?

• Advantages of Singleton Class over Static Class?

  Point 1) Singleton We can get the object of singleton and then pass to other methods. Static Class We can not pass static class to other methods as we pass objects Point 2) Singleton In future, it is easy to change the logic of of creating objects to some pooling mechanism. Static Class Very difficult to implement some pooling logic in case of static class. We would need to make that class as non-static and then make all the methods non-static methods, So entire your code needs to be changed. Point3:) Singleton Can Singletone class be inherited to subclass? Singleton class does not say any restriction of Inheritence. So we should be able to do this as long as subclass is also inheritence.There's nothing fundamentally wrong with subclassing a class that is intended to be a singleton. There are many reasons you might want to do it. and there are many ways to accomplish it. It depends on language you use. Static Class We can not inherit Static class to another Static class in C#. Think about it this way: you access static members via type name, like this: MyStaticType.MyStaticMember(); Were you to inherit from that class, you would have to access it via the new type name: MyNewType.MyStaticMember(); Thus, the new item bears no relationships to the original when used in code. There would be no way to take advantage of any inheritance relationship for things like polymorphism. span.fullpost {display:none;}

  - by Ram Shankar Yadav

  Hey Guys~ So the second day of the week starts, and we were all set for coming sessions on : - IS & Strategy and, - Changing Geo-politics & Business Environment We did our daily chores, rushed for breakfast, and reached Auditorioum, almost on time. IS & Strategy session was quite informative and interactive, and the prof. gave lot of examples, and it really gives us solid understanding by relating things with examples. Then goes the lunch, but the IS session over shoot for 15 minutes so our idea of taking a nap in lunch was not working out, but anyway we did our lunch and tried to sleep for 10-15 minutes. We got back and session on International Business started. Frankly, it’s a great topic, but we had tough time to be attentive, and it was hard to keep ourselves awake :P Anyhow the session came to an end, and we went to Library, and roamed around campus. Got back, had dinner, and went for a night walk, and ice-cream party. Lastly we did went to the platform inside the lake, and had a gag session, got back and  did “ITC eChaupal” case study. We have planned to visit Kali Mandir tomorrow, so I’ve to sleep for few hours…GN! Stay tuned for more… ram :)

• Thank you South Florida for a successful SPSouthFLA

  - by Leonard Mwangi

  I wanted to officially thank the organizers, speakers, volunteers and the attendees of SharePoint Saturday South Florida. Being the first event in South Florida the reception was phenomenon and the group of speakers from keynote by Joel Oleson to session’s speakers from well renowned speakers like John Holliday, Randy Disgrill, Richard Harbridge, Ameet Phadnis, Fabian Williams, Chris McNulty, Jaime Velez to organizers like Michael Hinckley amongst others. With my Business Intelligence (BI) presentation being on the last track of the day, I spent very quality time networking with these great guys and getting the insider scope on International SharePoint Community from Joel and his son which was mesmerizing. I had a very active audience to a point where we couldn’t accommodate all the contents within the 1hr allocated time because they were very engaged and wanted a deep dive session on news features like PowerPivot, enhancements on PerformancePoint, Excel Services amongst others in order to understand the business value and how SharePoint 2010 is making the self-service BI become a reality. These community events allows the attendees experience technology first hand and network with MVPs, authors, experts providing high quality educational sessions usually for free which is a reason to attend. I have made the slides for my session available for download for those interested http://goo.gl/VaH5x

• Meaning of offset in pygame Mask.overlap methods

  - by Alan

  I have a situation in which two rectangles collide, and I have to detect how much did they collide so so I can redraw the objects in a way that they are only touching each others edges. It's a situation in which a moving ball should hit a completely unmovable wall and instantly stop moving. Since the ball sometimes moves multiple pixels per screen refresh, it it possible that it enters the wall with more that half its surface when the collision is detected, in which case i want to shift it position back to the point where it only touches the edges of the wall. Here is the conceptual image it: I decided to implement this with masks, and thought that i could supply the masks of both objects (wall and ball) and get the surface (as a square) of their intersection. However, there is also the offset parameter which i don't understand. Here are the docs for the method: Mask.overlap Returns the point of intersection if the masks overlap with the given offset - or None if it does not overlap. Mask.overlap(othermask, offset) -> x,y The overlap tests uses the following offsets (which may be negative): +----+----------.. |A | yoffset | +-+----------.. +--|B |xoffset | | : :

• Does the use of mongodb enhance extending/changing database driven applications?

  - by developer10214

  When an application is created which need to store data, an SQL database is used very often. So did I in a lot of asp.net applications. The resulting applications have often an ORM like the entity framework and maybe a business layer. So when such an application needs to be extended(let's say you have to add a comment property to an object), you have to change/extend the database, then the ORM and the business layer and so on. To deploy the changes you have to update the target database and the application. I know that things like code first and fluent can make this approach easier. I tried mongodb, I only used the standard driver and I had to extend some objects and all I had to do was changing the code. So it feels that such approaches are much easier to realize when using mongodb. I don't have much experience with larger applications an mongodb. I know that a SQL database or mongodb doesn't fit for all needs and both have their pros and cons. I want to know if my feeling is right, if yes I would choose rather choose mongodb than SQL database.

• Example of DOD design (on a generic Zombie game)

  - by Jeffrey

  I can't seem to find a nice explanation of the Data Oriented Design for a generic zombie game (it's just an example, pretty common example). Could you make an example of the Data Oriented Design on creating a generic zombie class? Is the following good? Zombie list class: class ZombieList { GLuint vbo; // generic zombie vertex model std::vector<color>; // object default color std::vector<texture>; // objects textures std::vector<vector3D>; // objects positions public: unsigned int create(); // return object id void move(unsigned int objId, vector3D offset); void rotate(unsigned int objId, float angle); void setColor(unsigned int objId, color c); void setPosition(unsigned int objId, color c); void setTexture(unsigned int, unsigned int); ... void update(Player*); // move towards player, attack if near } Example: Player p; Zombielist zl; unsigned int first = zl.create(); zl.setPosition(first, vector3D(50, 50)); zl.setTexture(first, texture("zombie1.png")); ... while (running) { // main loop ... zl.update(&p); zl.draw(); // draw every zombie } Or would creating a generic World container that contains every action from bite(zombieId, playerId) to moveTo(playerId, vector) to createPlayer() to shoot(playerId, vector) to face(radians)/face(vector); and contains: std::vector<zombie> std::vector<player> ... std::vector<mapchunk> ... std::vector<vbobufferid> player_run_animation; ... be a good example? Whats the proper way to organize a game with DOD?

• Bullet Physic: Transform body after adding

  - by Mathias Hölzl

  I would like to transform a rigidbody after adding it to the btDiscreteDynamicsWorld. When I use the CF_KINEMATIC_OBJECT flag I am able to transform it but it's static (no collision response/gravity). When I don't use the CF_KINEMATIC_OBJECT flag the transform doesn't gets applied. So how to I transform non-static objects in bullet? DemoCode: btBoxShape* colShape = new btBoxShape(btVector3(SCALING*1,SCALING*1,SCALING*1)); /// Create Dynamic Objects btTransform startTransform; startTransform.setIdentity(); btScalar mass(1.f); //rigidbody is dynamic if and only if mass is non zero, otherwise static bool isDynamic = (mass != 0.f); btVector3 localInertia(0,0,0); if (isDynamic) colShape->calculateLocalInertia(mass,localInertia); btDefaultMotionState* myMotionState = new btDefaultMotionState(); btRigidBody::btRigidBodyConstructionInfo rbInfo(mass,myMotionState,colShape,localInertia); btRigidBody* body = new btRigidBody(rbInfo); body->setCollisionFlags(body->getCollisionFlags()|btCollisionObject::CF_KINEMATIC_OBJECT); body->setActivationState(DISABLE_DEACTIVATION); m_dynamicsWorld->addRigidBody(body); startTransform.setOrigin(SCALING*btVector3( btScalar(0), btScalar(20), btScalar(0) )); body->getMotionState()->setWorldTransform(startTransform);

• Migrating Forms to Java or ADF, the truth and no FUD

  - by Grant Ronald

  The question about migrating Forms to Java (or ADF or APEX) comes up time and time again.  I wanted to pull some core information together in a single blog post to address this question. The first question I always ask is "WHY" - Forms may still be a viable option for you so "if it ain't broke don't fix it".  Bottom line is whatever anyone tells you, its going to be a considerable effort and cost to migrate from Forms to something else so the business is going to want to know WHY you spend all those hard earned dollars switching from something that might have been serving you quite adequately. Second point, if you are going to switch, I would encourage you NOT to look at building a Forms clone.  So many times I see people trying to build an ADF application and EXACTLY mimic the Forms model - ADF is NOT a Forms clone.  You should be building to the sweet spot of your target technology, not your 20 year old client/server technology.  This is also the chance for the business to embrace change, so maybe look at new processes, channels and technology options that weren't available when you first developed your Forms applications. To help you understand what is involved, I've put together a number of resources. Thinking about migration of Forms to Java, ADF or APEX, read this to prepare yourself Oracle Forms to ADF: When, Why and How - this gives you an overview of our vision, directly from Oracle Product Management Redeveloping a Forms Application with Oracle JDeveloper and Oracle ADF.  This is a conference session from myself and Lynn Munsinger on how ADF can be used in a Forms migration/rewrite As someone who manages both Forms and ADF Product Management teams, I've a foot in either camp and am happy to see you use either tool.  However, I want you to be able to make an informed decision.  My hope is that there information sources will help you do that.

• Do you tend to write your own name or your company name in your code?

  - by Connell Watkins

  I've been working on various projects at home and at work, and over the years I've developed two main APIs that I use in almost all AJAX based websites. I've compiled both of these into DLLs and called the namespaces Connell.Database and Connell.Json. My boss recently saw these namespaces in a software documentation for a project for the company and said I shouldn't be using my own name in the code. (But it's my code!) One thing to bear in mind is that we're not a software company. We're an IT support company, and I'm the only full-time software developer here, so there's not really any procedures on how we should write software in the company. Another thing to bear in mind is that I do intend on one day releasing these DLLs as open-source projects. How do other developers group their namespaces within their company? Does anyone use the same class libraries in personal and in work projects? Also does this work the other way round? If I write a class library entirely at work, who owns that code? If I've seen the library through from start to finish, designed it and programmed it. Can I use that for another project at home? Thanks, Update I've spoken to my boss about this issue and he agrees that they're my objects and he's fine for me to open-source them. Before this conversation I started changing the objects anyway, which was actually quite productive and the code now suits this specific project more-so than it did previously. But thank you to everyone involved for a very interesting debate. I hope all this text isn't wasted and someone learns from it. I certainly did. Cheers,

• Object behaviour or separate class?

  - by Andrew Stephens

  When it comes to OO database access you see two common approaches - the first is to provide a class (say "Customer") with methods such as Retrieve(), Update(), Delete(), etc. The other is to keep the Customer class fairly lightweight (essentially just properties) and perform the database access elsewhere, e.g. using a repository. This choice of approaches doesn't just apply to database access, it can crop up in many different OOD scenarios. So I was wondering if one way is preferable over the other (although I suspect the answer will be "it depends")! Another dev on our team argues that to be truly OO the class should be "self-contained", i.e. providing all the methods necessary to manipulate and interact with that object. I personally prefer the repository approach - I don't like bloating the Customer class with all that functionality, and I feel it results in cleaner code having it elsewhere, but I can't help thinking I'm seriously violating core OO concepts! And what about memory implications? If I retrieve thousands of Customer objects I'm assuming those with the data access methods will take up a lot more memory than the property-only objects?

• OOP concept: is it possible to update the class of an instantiated object?

  - by Federico

  I am trying to write a simple program that should allow a user to save and display sets of heterogeneous, but somehow related data. For clarity sake, I will use a representative example of vehicles. The program flow is like this: The program creates a Garage object, which is basically a class that can contain a list of vehicles objects Then the users creates Vehicles objects, these Vehicles each have a property, lets say License Plate Nr. Once created, the Vehicle object get added to a list within the Garage object --Later on--, the user can specify that a given Vehicle object is in fact a Car object or a Truck object (thus giving access to some specific attributes such as Number of seats for the Car, or Cargo weight for the truck) At first sight, this might look like an OOP textbook question involving a base class and inheritance, but the problem is more subtle because at the object creation time (and until the user decides to give more info), the computer doesn't know the exact Vehicle type. Hence my question: how would you proceed to implement this program flow? Is OOP the way to go? Just to give an initial answer, here is what I've came up until now. There is only one Vehicle class and the various properties/values are handled by the main program (not the class) through a dictionary. However, I'm pretty sure that there must be a more elegant solution (I'm developing using VB.net): Public Class Garage Public GarageAdress As String Private _ListGarageVehicles As New List(Of Vehicles) Public Sub AddVehicle(Vehicle As Vehicles) _ListGarageVehicles.Add(Vehicle) End Sub End Class Public Class Vehicles Public LicensePlateNumber As String Public Enum VehicleTypes Generic = 0 Car = 1 Truck = 2 End Enum Public VehicleType As VehicleTypes Public DictVehicleProperties As New Dictionary(Of String, String) End Class NOTE that in the example above the public/private modifiers do not necessarily reflect the original code

• Capitalizing on JavaScript's prototypal inheritance

  - by keithjgrant

  JavaScript has a class-free object system in which objects inherit properties directly from other objects. This is really powerful, but it is unfamiliar to classically trained programmers. If you attempt to apply classical design patterns directly to JavaScript, you will be frustrated. But if you learn to work with JavaScript's prototypal nature, your efforts will be rewarded. ... It is Lisp in C's clothing. -Douglas Crockford What does this mean for a game developer working with canvas and HTML5? I've been looking over this question on useful design patterns in gaming, but prototypal inheritance is very different than classical inheritance, and there are surely differences in the best way to apply some of these common patterns. For example, classical inheritance allows us to create a moveableEntity class, and extend that with any classes that move in our game world (player, monster, bullet, etc.). Sure, you can strongarm JavaScript to work that way, but in doing so, you are kind of fighting against its nature. Is there a better approach to this sort of problem when we have prototypal inheritance at our fingertips?

• Announcing Oracle Environmental Accounting and Reporting

  - by Theresa Hickman

  Oracle just launched a new product called Oracle Environmental Accounting and Reporting designed to help company’s track and report their greenhouse emissions at the operational level.  Companies around the world are facing increasing pressure to improve their energy efficiency and reduce waste in their operations. Also, new worldwide greenhouse gas legislation is putting added pressure on companies to report the impact of their emissions and energy usage on the environment. Today, companies undergo extensive and expensive data audits to maintain a ledger of up-to-date emissions factors that compare figures on an annual basis. Existing “ad hoc” approaches utilizing manual or niche solutions have a high operational cost and weak data security and audit-ability. The ideal solution is to embed environmental usage within the mainstream business operations, such as recording energy usage at the time of invoice entry, and then report on those results. This is precisely what Oracle Environmental Accounting and Reporting is designed to do. You can now capture environmental data either electronically or manually; convert that to greenhouse gas emissions; comply with mandatory and voluntary greenhouse gas reporting schemes; and identify opportunities for CO2 emissions and cost reductions.   Oracle recently acquired the intellectual property for this solution which works with both Oracle E-Business Suite Release 12 and JD Edwards EnterpriseOne Release 9.0. For more information, visit Oracle Environmental Accounting and Reporting.

• What do I need to develop a PHP extension in lampp?

  - by Fernando Costa

  Actually I'm dealing with a trouble in my system, I have to delivery the system to clients and it was built in PHP, JS, ShellScript and SQL. I would like to encrypt the code or obfuscate it from eyes of others! Then someone from the community told me about build my own PHP extension, it sounds to me as a great idea, since it will not be with the main code of the system. But I have a problem doing this way, if a programmer get in the extensions and find it, all the hard work has gone. Then I'm here to ask again about this matter. What is the best way to hide my Business Logic from third parties? I know that has stuffs like IonCube, Zend Guard, and many others. But I'm looking something that I can build myself. Is PHP extension the right way to follow? Or some Half SaaS system, with dependencies (Business Logic) in a remote server? About the environment OS: Kernel Linux 2.6.37.1-1.2 - LAMPP (Apache 2.2, MySQL 5.5 PHP 5.3.8) In php generally the extension is located at /php/ext/ but in lampp I have no idea where it is, I just found a folder /opt/lampp/lib/php/extensions/ is that right place?

• Profit at Oracle OpenWorld 2012

  - by user462779

  It's only a week away: Oracle OpenWorld descends on San Francisco from September 30 to October 4. It's always a frantic week for the Profit editorial staff, but here's a few thing we've got going in San Francisco that you'll want to watch out for: Profit on Oracle OpenWorld Live: The Oracle video team will be broadcasting live from the event all week. I have a few interesting on-air interviews booked, including a conversation with business/technology researcher Andrew Mcafee (Monday Oct 1 @ 11:45am), Acorn Paper CEO David Weissberg (Tuesday, Oct 2 @ 12:15pm) and Abhay Parasnis, Oracle Senior Vice President, Oracle Public Cloud (Wednesday, Oct 3, @ 10:45am). Profit in the Oracle Partner Network Lounge: This summer, I worked with the amazing Oracle Partner Network (OPN) team to create the Profit Oracle Specialized Partner Edition 2012. It's a great catalog of Oracle partner success stories and insight into the OPN strategy from its leadership. Look for the special issue of Profit in the Oracle PartnerNetwork Lounge: the place where partners can meet formally or informally with colleagues, customers, prospects, and other industry professionals. Moscone South, Exhibit Hall, Room 100 Oracle Customer Experience Summit @ OpenWorld: There's been a lot of discussion within my editorial team (and content published, as well)about Customer Experience. To keep pace with this evolving subject, I'll be attending this special embedded conference on Wednesday and Thursday (Oct. 3-4). Especially looking forward to Seth Godin's presentation: he was one of the first experts we interviewed forProfit Online five years ago. The Executive Edge @ OpenWorld: Of course, my Oracle OpenWorld is mostly filled with meetings/interviews with Oracle customers about completed Oracle projects and the strategic impact of enterprise IT on business. The ideal place for these conversations is The Executive Edge @ OpenWorld embedded conference. Samovar Tea Lounge at Moscone Center: I spend my down time on the roof of Moscone North, preparing for meetings or having impromptu conversations with attendees at this little oasis overlooking Yerba Buena Gardens. Fee free to drop my for a chat! See you in San Francisco! -Aaron Lazenby

• Mutating Programming Language?

  - by MattiasK

  For fun I was thinking about how one could build a programming language that differs from OOP and came up with this concept. I don't have a strong foundation in computer science so it might be common place without me knowing it (more likely it's just a stupid idea :) I apologize in advance for this somewhat rambling question :) Anyways here goes: In normal OOP methods and classes are variant only upon parameters, meaning if two different classes/methods call the same method they get the same output. My, perhaps crazy idea, is that the calling method and class could be an "invisible" part of it's signature and the response could vary depending on who call's an method. Say that we have a Window object with a Break() method, now anyone (who has access) could call this method on Window with the same result. Now say that we have two different objects, Hammer and SledgeHammer. If Break need to produce different results based on these we'd pass them as parameters Break(IBluntObject bluntObject) With a mutating programming language (mpl) the operating objects on the method would be visible to the Break Method without begin explicitly defined and it could adopt itself based on them). So if SledgeHammer calls Window.Break() it would generate vastly different results than if Hammer did so. If OOP classes are black boxes then MPL are black boxes that knows who's (trying) to push it's buttons and can adapt accordingly. You could also have different permission sets on methods depending who's calling them rather than having absolute permissions like public and private. Does this have any advantage over OOP? Or perhaps I should say, would it add anything to it since you should be able to simply add this aspect to methods (just give access to a CallingMethod and CallingClass variable in context) I'm not sure, might be to hard to wrap one's head around, it would be kinda interesting to have classes that adopted themselves to who uses them though. Still it's an interesting concept, what do you think, is it viable?
