• Hosting StreamInsight applications using WCF

  - by gsusx

  One of the fundamental differentiators of Microsoft's StreamInsight compared to other Complex Event Processing (CEP) technologies is its flexible deployment model. In that sense, a StreamInsight solution can be hosted within an application or as a server component. This duality contrasts with most of the popular CEP frameworks in the current market which are almost exclusively server based. Whether it's undoubtedly that the ability of embedding a CEP engine in your applications opens new possibilities...(read more)

• The Game vs The Game Engine?

  - by Milo

  I was wondering if somebody could tell me how the game and the game engine fit into game development. Specifically what I mean is, the game engine does not actually have a game. So where I'm unclear about is basically, do game developpers build an engine, then create a new class that inherits from engine which becomes the game? Ex: class ShooterGame : public Engine { }; So basically i'm unclear on where the game code fits into the engine. Thanks

• Do game-theoretic considerations stand in the way of this market-based game-mechanic achieving its goals?

  - by BerndBrot

  Mechanic The mechanic is called "market manipulation" and is supposed to work like this: Players can enter the London Stock Exchange (LSE) LSE displays the stock prices of 8 to 10 companies and derivatives. This number is relatively small to ensure that players will collide in their efforts to manipulate the market in their favor. The prices are calculated based on real world prices of these companies and derivatives (in real time) any market manipulations that were conducted by the players any market corrections of the system Players can buy and sell shares with cash, a resource in the game, at current in-game market value Players can manipulate the market, i.e. let the price of a share either rise or fall, by some amount, over a certain period of time. Manipulating the market requires spending certain in-game resources and is therefore limited. The system continuously corrects market manipulations by letting the in-game prices converge towards their real world counterparts at a rate of 2% of the difference between the two per hour. Because of this market correction mechanism, pushing up prices (and screwing down prices) becomes increasingly difficult the higher (lower) the price already is. Goals Players are supposed to collide (and have incentives to collide) in their efforts to manipulate the market in their favor, especially when it comes to manipulation efforts by different groups. Prices should not resolve around any equilibrium points. The more variance the better. Band-wagoning should always involve risk (recognizing that prices start rising should not be a sure sign that they will keep rising so that everybody can make easy profits even when they don't manipulate the market themselves) Question Are there any game-theoretic considerations that prevent the mechanic from achieving these goals?

• Unity 3D game idea for a fun and teaching game

  - by rasheeda

  I have been brainstorming for months now on writing a unity 3D game for my final year computer science project. I have been learning unity for sometime now but comming up with a concept is quite difficult than i thought. The game has to be really fun and also educational, one that the school and community can benefit from. I am thinking about a third person game. where the player runs round in an enviroment, picks up coins and earn points. This alone wouldn't earn me points and I have been trying to find new ideas of my own and all over the net but to no avail. Hopefully you guys can help me out with an idea, and how to make the lecturers appreciate the game and also make kids wanna play play it for a reason. Thanks.

  Hi, We are web development company here in nepal. We are still in growth phase. Our URL: http://www.outsourcingnepal.com We have our clients demanding for web hosting and are now ready for getting hosting package to host websites of our clients. Since we have multiple clients and they want their own cpanel for self configuration, only creating ftp channel is not appropirate. So their own cpanel is needed. So i thought of reseller package. When i searched for reseller package i came across with vps, cloud hosting and shared hosting. So now confused which one is better for our company?

• game inventory/bag system javascript html5 game

  - by Tom Burman

  im building an RPG game using html5's canvas and javascript. Its tile based and im using an array to created my game map. I would like the player to have a bag/inventory so when they select or land on a tile that has an item on it, they can click on it and store it in their bag/inventory. I was thinking of using a 2d array to store the value of the item tile, a bit like my map is doing, so when the player lands on, lets say a rope tile which is tileID 4, the value 4 is pushed into the next array position available, then reloop through the array and reprint it to the screen. For an example of what im trying to achieve visually, would be like runescapes inventory, but dumbed down a bit. I appreciate any views and answers. Im not great at javascript coding so please be patient Thanks Tom

• The Interaction between Three-Tier Client/Server Model and Three-Tier Application Architecture Model

  The three-tier client/server model is a network architectural approach currently used in modern networking. This approach divides a network in to three distinct components. Three-Tier Client/Server Model Components Client Component Server Component Database Component The Client Component of the network typically represents any device on the network. A basic example of this would be computer or another network/web enabled devices that are connected to a network. Network clients request resources on the network, and are usually equipped with a user interface for the presentation of the data returned from the Server Component. This process is done through the use of various software clients, and example of this can be seen through the use of a web browser client. The web browser request information from the Server Component located on the network and then renders the results for the user to process. The Server Components of the network return data based on specific client request back to the requesting client.  Server Components also inherit the attributes of a Client Component in that they are a device on the network and that they can also request information from other Server Components. However what differentiates a Client Component from a Server Component is that a Server Component response to requests from devices on the network. An example of a Server Component can be seen in a web server. A web server listens for new requests and then interprets the request, processes the web pages, and then returns the processed data back to the web browser client so that it may render the data for the user to interpret. The Database Component of the network returns unprocessed data from databases or other resources. This component also inherits attributes from the Server Component in that it is a device on a network, it can request information from other server components and database components, and it also listens for new requests so that it can return data when needed. The three-tier client/server model is very similar to the three-tier application architecture model, and in fact the layers can be mapped to one another. Three-Tier Application Architecture Model Presentation Layer/Logic Business Layer/Logic Data Layer/Logic The Presentation Layer including its underlying logic is very similar to the Client Component of the three-tiered model. The Presentation Layer focuses on interpreting the data returned by the Business Layer as well as presents the data back to the user.  Both the Presentation Layer and the Client Component focus primarily on the user and their experience. This allows for segments of the Business Layer to be distributable and interchangeable because the Presentation Layer is not directly integrated in with Business Layer. The Presentation Layer does not care where the data comes from as long as it is in the proper format. This allows for the Presentation Layer and Business Layer to be stored on one or more different servers so that it can provide a higher availability to clients requesting data. A good example of this is a web site that uses load balancing. When a web site decides to take on the task of load balancing they must obtain a network device that sits in front of a one or machines in order to distribute the request across multiple servers. When a user comes in through the load balanced device they are redirected to a specific server based on a few factors. Common Load Balancing Factors Current Server Availability Current Server Response Time Current Server Priority The Business Layer and corresponding logic are business rules applied to data prior to it being sent to the Presentation Layer. These rules are used to manipulate the data coming from the Data Access Layer, in addition to validating any data prior to being stored in the Data Access Layer. A good example of this would be when a user is trying to create multiple accounts under one email address. The Business Layer logic can prevent duplicate accounts by enforcing a unique email for every new account before the data is even stored in the Data Access Layer. The Server Component can be directly tied to this layer in that the server typically stores and process the Business Layer before it is returned to the end-user via the Presentation Layer. In addition the Server Component can also run automated process through the Business Layer on the data in the Data Access Layer so that additional business analysis can be derived from the data that has been already collected. The Data Layer and its logic are responsible for storing information so that it can be easily retrieved. Typical in most modern applications data is stored in a database management system however data can also be in the form of files stored on a file server. In addition a database can take on one of several forms. Common Database Formats XML File Pipe Delimited File Tab Delimited File Comma Delimited File (CSV) Plain Text File Microsoft Access Microsoft SQL Server MySql Oracle Sybase The Database component of the Networking model can be directly tied to the Data Layer because this is where the Data Layer obtains the data to return back the Business Layer. The Database Component basically allows for a place on the network to store data for future use. This enables applications to save data when they can and then quickly recall the saved data as needed so that the application does not have to worry about storing the data in memory. This prevents overhead that could be created when an application must retain all data in memory. As you can see the Three-Tier Client/Server Networking Model and the Three-Tiered Application Architecture Model rely very heavily on one another to function especially if different aspects of an application are distributed across an entire network. The use of various servers and database servers are wonderful when an application has a need to distribute work across the network. Network Components and Application Layers Interaction Database components will store all data needed for the Data Access Layer to manipulate and return to the Business Layer Server Component executes the Business Layer that manipulates data so that it can be returned to the Presentation Layer Client Component hosts the Presentation Layer that  interprets the data and present it to the user

• What makes a game a game vs something else like a puzzle or a toy?

  - by Shannon John Clark

  Famously the Sims and similar games have been described by some designers as Toys and not "really" games. I'm curious if there is a good answer to what makes something a game. For example many companies sell Sudoku games - EA has an iPhone one, IronSudoku offers a great web based one, and there are countless others on most platforms. Many newspapers publish Sudoku puzzles in their print editions and often online. What differentiates a game from a puzzle? (or are all Sudoku "games" misnamed?) I'm not convinced there is a simple or easy answer - but I'd love to be proven wrong. I've seen some definitions and emphasize "rules" as core to something being a game (vs. "real life") but puzzles have rules as well - as do many other things. I'm open to answers that either focus only on computer games (on any platform) or which expand to include games and gameplay across many platforms. Here to I'm not fully convinced the lines are clear - is a "game" of D&D played over a virtual tabletop with computer dice rollers, video & audio chat a computer game or something else? (I'd lean towards something else - but where do you draw that line?)

• Development costs of an indie multiplayer arcade shooter

  - by VorteX

  Me and a friend of mine have been wanting to remake one of our favorite games of all time (007: Nightfire) for a long time now. However, remaking a game likes this is really complicated because of the rights to the Bond-franchise. That site was created months ago, and by doing so we have found some great people (modelers, level designers, etc.) that want to help, but our plans have changed a little bit. Our current plan is to create a multiplayer-only remake of the original game, removing all the Bond-references so that the rights shouldn't be a problem anymore. We still want to create the game using the UDK and SteamWorks for both PC and Mac. Currently there's 3 things I need to find out: The costs of creating an arcade shooter like this. We want to use crowdfunding to fund the project. The best way to manage a project like this over the internet. Our current team consists of people all over the world, and we need a central place to discuss, collaborate and store our files. The best place to find suitable people for this project. We already have some modelers and level designers but we also need animators, artists, programmers, etc. I believe creating an arcade game like this with a small team is feasible. The game in a nutshell: ±10 maps, ±20 weapons, ±12 game modes, weapon/armor pickups, grapple hook gadget, no ADS, uses SteamWorks, online matchmaking, custom games, AI bots, appearance selection, level progression using XP (no unlocks), achievements. Does anyone know where to start? Any help is appreciated.

• Connecting to Microsoft Excel using Oracle Data Integrator

  - by julien.testut

  The posts in this series assume that you have some level of familiarity with ODI. The concepts of Topology, Data Server, Physical and Logical Architecture are used here assuming that you understand them in the context of ODI. If you need more details on these elements, please refer to the ODI Tutorial for a quick introduction, or to the complete ODI documentation for more details. In this post I will describe how a Microsoft Excel spreadsheet can be used in Oracle Data Integrator. Microsoft Excel is one of the many different technologies you can leverage in ODI as a source or as a target. Prepare your Excel spreadsheet Prior to using a Microsoft Excel spreadsheet in ODI we need to specify a name for the different cell tables we want to use. You can have multiple names in the same spreadsheet. First open up a Microsoft Excel spreadsheet, we will need to define a named range.

• Mouse input not updating in custom XNA/Winforms panel

  - by ChocoMan

  I have a custom Panel residing within my WinForm. the custom Panel holds the XNA rendering. So far, I've rendered an 3D test model. What I'm doing now is trying to handle the input.Using a camera from another working game, keyboard input works fine moving the camera in all 6 directions. But when it comes to handling the mouse to yaw and pitch the camera, nothing happens. I've searched about to see if anyone has come across this problem, but found no testable solutions to my problem. Does anyone understand as to what may be causing the Mouse not to be called when moved? Within MainForm constructor: public MainForm() { InitializeComponent(); Mouse.WindowHandle = panel3D.Handle; } Panel3D.cs Custom XNA Panel class FreeCamera.cs FreeCamera class

• Improving first person camera and implementing third person camera

  - by brainydexter

  I want to improve upon my first person camera implementation and extend it to, so the user can toggle between third person/first person view. My current setup: draw():: glPushMatrix(); m_pCamera->ApplyCameraTransform(); // Render gameObjects glPopMatrix(); Camera is strongly coupled to the player, so much so, that it is a friend of player. This is what the Camera::ApplyCameraTransform looks like: glm::mat4 l_TransformationMatrix; m_pPlayer->m_pTransformation->GetTransformation(l_TransformationMatrix, false); l_TransformationMatrix = glm::core::function::matrix::inverse(l_TransformationMatrix); glMultMatrixf(glm::value_ptr(l_TransformationMatrix)); So, I take the player's transformation matrix and invert it to yield First person camera view. Since, Third person camera view is just a 'translated' first person view behind the player; what would be a good way to improve upon this (keeping in mind that I will be extending it to Third person camera as well. Thanks

• Oracle Healthcare Data Warehouse Foundations RELEASED!

  - by Glen McCallum

  Since I joined Oracle I've been working on Oracle Healthcare Data Warehouse Foundations (OHDF). It was officially released earlier this month at HIMSS. But for over 2 months prior to that I had to keep it a secret. It was so tough; I didn't even tell my family when they asked me what I was working on. Anyway, OHDF is an enterprise healthcare data model. Unlike Healthcare Transaction Base, OHDF is in 3rd normal form. It is logical and reasonably easy to understand for anyone with some experience in the healthcare domain. OHDF is emerging as the core of Oracle's healthcare business intelligence applications.

• Game show game engine [closed]

  - by Red

  So, I am pretty new to the world of game development, so I am a bit fuzzy on what I require. Could someone suggest a game engine that I could use? I need it to be light weight (my game won't require that much power) and have networking functionality for multiplay or even an MMO aspect. The game I am making is like a game show, so it is your basic choose and answer hit the buzzer kind of game. Any suggestions? I would also like it to be open source or at the least free. I would like to support open source projects.

• OWB 11gR2 &ndash; Flexible and extensible

  - by David Allan

  The Oracle data integration extensibility capabilities are something I love, nothing more frustrating than a tool or platform that is very constraining. I think extensibility and flexibility are invaluable capabilities in the data integration arena. I liked Uli Bethke's posting on some extensibility capabilities with ODI (see Nesting ODI Substitution Method Calls here), he has some useful guidance on making customizations to existing KMs, nice to learn by example. I thought I'd illustrate the same capabilities with ODI's partner OWB for the OWB community. There is a whole new world of potential. The LKM/IKM/CKM/JKMs are the primary templates that are supported (plus the Oracle Target code template), so there is a lot of potential for customizing and extending the product in this release. Enough waffle... Diving in at the deep end from Uli's post, in OWB the table operator has a number of additional properties in OWB 11gR2 that let you annotate the column usage with ODI-like properties such as the slowly changing usage or for your own user-defined purpose as in Uli's post, below you see for the target table SALES_TARGET we can use the UD5 property which when assigned the code template (knowledge module) which has been modified with Uli's change we can do custom things such as creating indices - provides The code template used by the mapping has the additional step which is basically the code illustrated from Uli's posting just used directly, the ODI 10g substitution references also supported from within OWB's runtime. Now to see whether this does what we expect before we execute it, we can check out the generated code similar to how the traditional mapping generation and preview works, you do this by clicking on the 'Inspect Code' button on the execution units code template assignment. This then  creates another tab with prefix 'Code - <mapping name>' where the generated code is put, scrolling down we find the last step with the indices being created, looks good, so we are ready to deploy and execute. After executing the mapping we can then use the 'Audit Information' panel (select the mapping in the designer tree and click on View/Audit Information), this gives us a view of the execution where we can drill into the tasks that were executed and inspect both the template and the generated code that was executed and any potential errors. Reflecting back on earlier versions of OWB, these were the kinds of features that were always highly desirable, getting under the hood of the code generation and tweaking bit and pieces - fun and powerful stuff! We can step it up a bit here and explore some further ideas. The example below is a daisy-chained set of execution units where the intermediate table is a target of one unit and the source for another. We want that table to be a global temporary table, so can tweak the templates. Back to the copy of SQL Control Append (for demo purposes) we modify the create target table step to make the table a global temporary table, with the option of on commit preserve rows. You can get a feel for some of the customizations and changes possible, providing some great flexibility and extensibility for the data integration tools.

• What features would you like to have in PHP?

  - by StasM

  Since it's the holiday season now and everybody's making wishes, I wonder - which language features you would wish PHP would have added? I am interested in some practical suggestions/wishes for the language. By practical I mean: Something that can be practically done (not: "I wish PHP would guess what my code means and fix bugs for me" or "I wish any code would execute under 5ms") Something that doesn't require changing PHP into another language (not: "I wish they'd drop $ signs and use space instead of braces" or "I wish PHP were compiled, statically typed and had # in it's name") Something that would not require breaking all the existing code (not: "Let's rename 500 functions and change parameter order for them") Something that does change the language or some interesting aspect of it (not: "I wish there was extension to support for XYZ protocol" or "I wish bug #12345 were finally fixed") Something that is more than a rant (not: "I wish PHP wouldn't suck so badly") Anybody has any good wishes? Mod edit: Stanislav Malyshev is a core PHP developer.

• Programming languages, positional languages and natural languages

  - by Vitalij Zadneprovskij

  Some programming languages are modeled on machine code, like assembly languages. Other languages are modeled on a natural language, the English language. Others are not modeled on either machine code or natural language. Languages such as PROLOG, for example, don't follow either model. I came across this Perl module Lingua::Romana::Perligata, that allows to write programs using a syntax that is very similar to Latin. Are there programming languages that have less positional syntax? Are there other languages or modules that allow you to write in syntaxes inspired by other natural languages, like French, Hebrew or Farsi? There is a very long list on Wikipedia, but most of those projects are dead. There is a related question on StackOverflow. The answer that was accepted is "Use Google".

• Product application - is it a product or product variation

  - by jamesnov

  I'm dealing with a lot of vehicle specific products, and I've been trying to determine whether to convert the variants/fit option into individual products. I currently put the vehicle specific items under a product: Product: Widget Hood Deflectors Option1: 07-11 Silverado/Sierra, SKU1 Option2: 09-11 Ram, SKU2 etc. Take a hood/bug deflector for example. They all share the same description, and specifications for the most part. They look very similar, but the shape/appearance could vary significantly depending on the vehicle it is going on. Another example could be a suspension lift kit. Each one is engineered for a specific vehicle application. What would be the product "Widget Super Duper 4 inch lift kit", or "Widget Jeep 07-11 Super Duper 4 inch lift kit"? If I converted the variants to a product, then I have a lot more products (some so called products or product lines have hundreds of applications), when no vehicle is selected, but if I require a vehicle to be selected, then the product results would be basically the same, and specific for that vehicle. The description would also be longer: Product: Widget Silverado/Sierra 07-11 Hood Deflector With the fit as a variants/option, then I have fewer products, but I could have a huge list of options. Product: Widget Hood Deflectors Options: Fit/Vehicle Am I doing things right by having product applications as variants, or am I treating a product line as a product?
