• 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.

• On the art of self-promotion

  - by Tony Davis

  I attended Brent Ozar’s Building the Fastest SQL Servers session at Tech Ed last week, and found myself engulfed in a ‘perfect storm’ of excellent technical and presentational skills coupled with an astute awareness of the value of promoting one’s work. I spend a lot of time at such events talking to developers and DBAs about the value of blogging and writing articles, and my impression is that some could benefit from a touch less modesty and a little more self-promotion. I sense a reticence in many would-be writers. Is what I have to say important enough? Haven’t far more qualified and established commentators, MVPs and so on, already said it? While it’s a good idea to pick reasonably fresh and interesting topics, it’s more important not to let such fears lead to writer’s block. In the eyes of any future employer, your published writing is an extension of your resume. They will not care that a certain MVP knows how to solve problem x, but they will be very interested to see that you have tackled that same problem, and solved it in your own way, and described the process in your own voice. In your current job, your writing is one of the ways you can express to your peers, and to the organization as a whole, the value of what you contribute. Many Developers and DBAs seem to rely on the idea that their work will speak for itself, and that their skill shines out from it. Unfortunately, this isn’t always true. Many Development DBAs, for example, will be painfully aware of the massive effort involved in tuning and adding resilience to rapidly developed applications. However, others in the organization who are unaware of what’s involved in getting an application that is ‘done’ ready for production may dismiss such efforts as fussiness or conservatism. At the dark end of the development cycle, chickens come home to roost, but their droppings tend to land on those trying to clear up the mess. My advice is this: next time you fix a bug or improve the resilience or performance of a database or application, make sure that you use team meetings, informal discussions and so on to ensure that people understand what the problem was and what you had to do to fix it. Use your blog to describe, generally, the process you adopted, the resources you used and the insights that came from your work. Encourage your colleagues to do the same. By spreading the art of self-promotion to everyone involved in an IT project, we get a better idea of the extent of the work and the value of the contribution of all the team members. As always, we’d love to hear what you think. This very week, Simple-talk launches its new blogging platform. If any of this has moved you to ‘throw your hat into the ring’, drop us a mail at [email protected]. Cheers, Tony.

• Help with Collision of spawned object(postion fixed) with objects that there are translating on screen

  - by Amrutha

  Hey guys I am creating a game using Corona SDK and so coding it in Lua. So there are 2 separate functions, To translate the hit objects and change their color when they are tapped The link below is the code I am using to for the first function http://developer.anscamobile.com/sample-code/fishies Spawn objects that will hit the translating objects on collision. Alos on collision the spawned object disappears and the translating object bears a color(indicating the collision). In addition the size of this spawned object is dependent on i/p volume level. The function I have written is as follows, --VOICE INPUT CODE local r = media.newRecording() r:startRecording() r:startTuner() --local function newBar() -- local bar = display.newLine( 0, 0, 1, 0 ) -- bar:setColor( 0, 55, 100, 20 ) -- bar.width = 5 -- bar.y=400 -- bar.x=20 -- return bar --end local c1 = display.newImage("str-minion-small.png") c1.isVisible=false local c2 = display.newImage("str-minion-mid.png") c2.isVisible=false local c3 = display.newImage("str-minion-big.png") c3.isVisible=false --SPAWNING local function spawnDisk( event ) local phase = event.phase local volumeBar = display.newLine( 0, 0, 1, 0 ) volumeBar.y = 400 volumeBar.x = 20 -- volumeBar.isVisible=false local v = 20*math.log(r:getTunerVolume()) local MINTHRESH = 30 local LEFTMARGIN = 20 local v2 = MINTHRESH + math.max (v, -MINTHRESH) v2 = (display.contentWidth - 1 * LEFTMARGIN ) * v2 / MINTHRESH volumeBar.xScale = math.max ( 20, v2 ) local l = volumeBar.xScale local cnt1 = 0 local cnt2 = 0 local cnt3 = 0 local ONE =1 local val = event.numTaps --local px=event.x --local py=event.y if "ended" == phase then --audio.play( popSound ) --myLabel.isVisible = false if l > 50 and l <=150 then -- c1:setFillColor(10,105,0) -- c1.isVisible=false c1.x=math.random( 10, 450 ) c1.y=math.random( 10, 300 ) physics.addBody( c1, { density=1, radius=10.0 } ) c1.isVisible=true cnt1= cnt1+ ONE return c1 elseif l > 100 and l <=250 then --c2:setFillColor(200,10,0) c2.x=math.random( 10, 450 ) c2.y=math.random( 10, 300 ) physics.addBody( c2, { density=2, radius=9000.0 } ) c2.isVisible=true cnt2= cnt2+ ONE return c2 elseif l >=250 then c3.x=math.random( 40, 450 ) c3.y=math.random( 40, 300 ) physics.addBody( c3, { density=2, radius=7000.0 , bounce=0.0 } ) c3.isVisible=true cnt3= cnt3+ ONE return c3 end end end buzzR:addEventListener( "touch", spawnDisk ) -- touch the screen to create disks Now both functions work fine independently but there is no collision happening. Its almost as if the translating object and the spawn object are on different layers. The translating object passes through the spawn object freely. Can anyone please tell me how to resolve this problem. And how can I get them to collide. Its my first attempt at game development, that too for a mobile platform so would appreciate all help. Also if I have not been specific do let me know. I ll try to frame the query better :). Thanks in advance.

• How does gluLookAt work?

  - by Chan

  From my understanding, gluLookAt( eye_x, eye_y, eye_z, center_x, center_y, center_z, up_x, up_y, up_z ); is equivalent to: glRotatef(B, 0.0, 0.0, 1.0); glRotatef(A, wx, wy, wz); glTranslatef(-eye_x, -eye_y, -eye_z); But when I print out the ModelView matrix, the call to glTranslatef() doesn't seem to work properly. Here is the code snippet: #include <stdlib.h> #include <stdio.h> #include <GL/glut.h> #include <iomanip> #include <iostream> #include <string> using namespace std; static const int Rx = 0; static const int Ry = 1; static const int Rz = 2; static const int Ux = 4; static const int Uy = 5; static const int Uz = 6; static const int Ax = 8; static const int Ay = 9; static const int Az = 10; static const int Tx = 12; static const int Ty = 13; static const int Tz = 14; void init() { glClearColor(0.0, 0.0, 0.0, 0.0); glEnable(GL_DEPTH_TEST); glShadeModel(GL_SMOOTH); glEnable(GL_LIGHTING); glEnable(GL_LIGHT0); GLfloat lmodel_ambient[] = { 0.8, 0.0, 0.0, 0.0 }; glLightModelfv(GL_LIGHT_MODEL_AMBIENT, lmodel_ambient); } void displayModelviewMatrix(float MV[16]) { int SPACING = 12; cout << left; cout << "\tMODELVIEW MATRIX\n"; cout << "--------------------------------------------------" << endl; cout << setw(SPACING) << "R" << setw(SPACING) << "U" << setw(SPACING) << "A" << setw(SPACING) << "T" << endl; cout << "--------------------------------------------------" << endl; cout << setw(SPACING) << MV[Rx] << setw(SPACING) << MV[Ux] << setw(SPACING) << MV[Ax] << setw(SPACING) << MV[Tx] << endl; cout << setw(SPACING) << MV[Ry] << setw(SPACING) << MV[Uy] << setw(SPACING) << MV[Ay] << setw(SPACING) << MV[Ty] << endl; cout << setw(SPACING) << MV[Rz] << setw(SPACING) << MV[Uz] << setw(SPACING) << MV[Az] << setw(SPACING) << MV[Tz] << endl; cout << setw(SPACING) << MV[3] << setw(SPACING) << MV[7] << setw(SPACING) << MV[11] << setw(SPACING) << MV[15] << endl; cout << "--------------------------------------------------" << endl; cout << endl; } void reshape(int w, int h) { float ratio = static_cast<float>(w)/h; glViewport(0, 0, w, h); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective(45.0, ratio, 1.0, 425.0); } void draw() { float m[16]; glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glGetFloatv(GL_MODELVIEW_MATRIX, m); gluLookAt( 300.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 1.0f, 0.0f ); glColor3f(1.0, 0.0, 0.0); glutSolidCube(100.0); glGetFloatv(GL_MODELVIEW_MATRIX, m); displayModelviewMatrix(m); glutSwapBuffers(); } int main(int argc, char** argv) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH); glutInitWindowSize(400, 400); glutInitWindowPosition(100, 100); glutCreateWindow("Demo"); glutReshapeFunc(reshape); glutDisplayFunc(draw); init(); glutMainLoop(); return 0; } No matter what value I use for the eye vector: 300, 0, 0 or 0, 300, 0 or 0, 0, 300 the translation vector is the same, which doesn't make any sense because the order of code is in backward order so glTranslatef should run first, then the 2 rotations. Plus, the rotation matrix, is completely independent of the translation column (in the ModelView matrix), then what would cause this weird behavior? Here is the output with the eye vector is (0.0f, 300.0f, 0.0f) MODELVIEW MATRIX -------------------------------------------------- R U A T -------------------------------------------------- 0 0 0 0 0 0 0 0 0 1 0 -300 0 0 0 1 -------------------------------------------------- I would expect the T column to be (0, -300, 0)! So could anyone help me explain this? The implementation of gluLookAt from http://www.mesa3d.org void GLAPIENTRY gluLookAt(GLdouble eyex, GLdouble eyey, GLdouble eyez, GLdouble centerx, GLdouble centery, GLdouble centerz, GLdouble upx, GLdouble upy, GLdouble upz) { float forward[3], side[3], up[3]; GLfloat m[4][4]; forward[0] = centerx - eyex; forward[1] = centery - eyey; forward[2] = centerz - eyez; up[0] = upx; up[1] = upy; up[2] = upz; normalize(forward); /* Side = forward x up */ cross(forward, up, side); normalize(side); /* Recompute up as: up = side x forward */ cross(side, forward, up); __gluMakeIdentityf(&m[0][0]); m[0][0] = side[0]; m[1][0] = side[1]; m[2][0] = side[2]; m[0][1] = up[0]; m[1][1] = up[1]; m[2][1] = up[2]; m[0][2] = -forward[0]; m[1][2] = -forward[1]; m[2][2] = -forward[2]; glMultMatrixf(&m[0][0]); glTranslated(-eyex, -eyey, -eyez); }

• 50 Billion Served: Java Embedded on Devices

  - by Tori Wieldt

  It doesn't matter if it is 50 billion or 24 billion, just suffice it to stay that there will be MANY connected devices in the year 2020. With just 24 billion devices, they will outnumber humans six to one! So as a developer, you don't want to ignore this opportunity. What if you could use your Java skills and deploy an app to a fraction of these devices (don't be greedy, how about just, say, 118,000 of them)? Fareed Suliman, Java ME Product Manager had lots of good news for Java Developers in his presentation Modernizing the Explosion of Advanced Microcontrollers with Embedded Java at ARM TechCon in Santa Clara, CA last week. "A radical architecture shift is underway in this space, from proprietary to standards-based," he explained.  He pointed out several advantages to using Embedded Java for devices: Java is a proven and open standard. Java provides connectivity, encryption, location, and web services APIs. You don't have to focus on and keep reinventing the plumbing below the JVM. Abstracting the software from the hardware allows you to repeat your app across many devices. Abstracting the software from the hardware allows allows parallel development so you can get your app done more quickly. You already know Java (or you can hire lots of Java talent). Java is a full ecosystem, with Java Embedded plugins for IDEs like Eclipse and NetBeans. Java ME allows for in-field software upgrades. Suliman mentioned two ways developers can start using Java Embedded today:  Java ME Embedded Suite 7.0 Oracle Java Embedded Suite is a new packaged solution from Oracle (including Java DB, GlassFish for Embedded Suite, Jersey Web Services Framework, and Oracle Java SE Embedded 7 platform), created to provide value added services for collecting, managing, and transmitting data to embedded devices such as gateways and concentrators. Oracle Java ME Embedded 3.2 Oracle Java ME Embedded 3.2 is designed and optimized to meet the unique requirements of small embedded, low power devices such as micro-controllers and other resource-constrained hardware without screens or user interfaces. Think tiny. Really tiny. And think big.  Read more about Java Embedded at the Oracle Technology Network, and read The Java Source blog Java Embedded Releases from September.

• Ideas for time-keeping in a webbased RPG?

  - by ashy_32bit

  I'm assigned a task of doing the preliminary research stuff for a web-based MMO RPG. Now my buggiest problem here is "web based" vs "MMO RPG". I did some research about time keeping systems and I'm totally confused as how exactly something as real-time as an MMO-RPG can work on some pull-only (unidirectional) platform like HTTP. I know there is also a turn-based alternative to time keeping but can it work in an MMO setting ? EDIT: Take a battle for example, player A (human) wants to attack Player B (also human) in the open. How does it work when when player A issues the "attack" command on player B ? how do I inform player B that he is being attacked ? and then how exactly the battle goes on between the two in an HTTP based communication channel? To my knowledge this is impossible unless you resort to another technology (HTML is 1-way, that is you can just ask server and get response, server can't update you unless being asked to. this is very well-known and simply explained). So I though maybe I can somehow change the whole timekeeping model from real-time to a more non-real-time model (towards a turn based RPG for example) and somehow work around the whole problem of "interactivity". EDIT2: It is not that I don't wanna use any server side technologies. For sure it is not gonna work client-side-only even for the most trivial of the multi-player games, let alone an RPG. So sure there would be a (probably complex) server side component to it (the so called Game Engine I suppose). The problem is not the technology that implements the logic (game mechanics) bits but the communication technology and how it limits the game mechanics abilities (like how real-time or turn based it is gonna be). HTTP is a request-response protocol meaning you get served only if you ask for it (explicitly send a GET or POST request to the server). HTTP server can not inform you if anything of interest happens in the game world unless you refresh the page (as some suggested) or you use some bi-directional tech (totally different animals) like Flash, WebSock, HTML5 etc etc. So maybe the question is: Is it possible to implement a MMORPG using only HTML5/PHP and no periodic page refreshes? if so what would be rules to make it an MMO-RPG? Can't explain it any clearer. Sorry :D

• How To: Using SimpleMembserhipProvider with MySql Connector/Net.

  - by Francisco Tirado

  Now on Connector/Net 6.9 the users will have the ability to use SimpleMembership Provider on MVC4 templates. The configuration is very simple and also have compatibility with OAuth, in this post we'll explain step by step how to configure it in a MVC 4 Web Application. Requirements  The requirements to use SimpleMembership with Connector/Net are: Install Connector/Net 6.9, or download the No Install version. Net Framework 4.0 or greater. MVC 4  Visual Studio 2012 or newer version Creating and configuring a new project In this example we'll use VS2012 to create the project basis on the Internet Aplication template and using Entity Framework to manage the User model. Open VS 2012 and create a new project, we'll create a new MVC 4 Web Application and configure the project to use Net Framework 4.5. Type a name for the project and then click “Ok”. In the next dialog we'll choose the “Internet Application” template and use Razor as engine without creating a test project. Click “Ok” to continue. Now we have a new project with the templates necessaries to run a Web Application with the default values. We'll use the current files to continue working. If you have installed Connector/Net you can skip this step, if you don't have installed but you're planning to do it, please install it and continue with the next step. If you're using the No Install version of Connector/Net we'll need to add the references to our project, the assemblies needed are: MySql.Data, MySql.Data.Entities and MySql.Web. Be sure that the assemblies chosen match the Net Framework version used in our project and the MySql.Data.Entities is compatible with EF5 (EF5 is the default added by the project). Now open the “web.config” file, and under the <connectionStrings> node add a connection string that points to a MySql instance. We'll use the following connection configuration: <add name="MyConnection" connectionString="server=localhost;UserId=root;password=pass;database=MySqlSimpleMembership;" providerName="MySql.Data.MySqlClient"/> Under the node <system.web> we'll add the following configuration: <membership defaultProvider="MySqlSimpleMembershipProvider"><providers><clear/><add name="MySqlSimpleMembershipProvider" type="MySql.Web.Security.MySqlSimpleMembershipProvider,MySql.Web,Version=6.9.3.0,Culture=neutral,PublicKeyToken=c5687fc88969c44d" applicationName="MySqlSimpleMembershipTest" description="MySQLdefaultapplication" connectionStringName="MyConnection"  userTableName="UserProfile" userIdColumn="UserId" userNameColumn="UserName" autoGenerateTables="True"/></providers></membership> In the previous configuration the mandatory properties are: connectionStringName, userTableName, userIdColumn, userNameColumn and autoGenerateTables. If the other properties are not provided a default value is set to it but if the mandatory properties are not set a ProviderException will be thrown. The valid properties for the MySqlSimpleMembership are the same used for MySqlMembership plus the mandatory fields. UserTableName: Name of the table where will be stored the user, this table is independent from the schema generated by the provider and can be edited later by the user. UserId: name of the column that will store the id for the records in the userTableName. UserName : name of the column that will store the name/user for the records in the userTableName. The connectionStringName property must match a connection string defined in web.config file. Once the configuration is done in web.config, we need to be sure that our database context for the Users Table point to the right connection string. In our case we just need to update the class UsersContext in the file AcountModel.cs in the Models folder. The file also contains the UserProfile class which match the configuration for our UserTable. Other class that needs to be updated is the SimpleMembershipInitializer in the file InitializeSimpleMembershipAttribute.cs in the Filters folder. In that class we'll see a call to the method “WebSecurity.InitializeDatabaseConnection”, in that call is where we need to update the parameters to match our configuration. If the database that you configure in your connection string doesn't exists, you need to create it empty. Now we're ready to run our web application, press F5 or the Run button in the tool bar. You'll see the following screen: If you go to your database used by the application you'll see some tables created, now we are using SimpleMembership. Now create a user, click on “Register” at the top-right in the web page. Type your user name and password, then click on “Register”. You'll be redirected to the home page and you'll see the name of your user at the top-right page. If you take a look on the tables just created in your database you will find the data about the user you just register. In our case the tables that contains the information are UserProfile and Webpages_Membership.  Configuring OAuth Other option to access your website will be using OAuth, so you can validate an user using an external account like Facebook, Twitter, Google, etc. In this post we'll enable the authentication for Google account in our application. Go to the class AuthConfig.cs in the folder App_Start. In the method “RegisterAuth” uncomment the last line where is the call to the method “OauthWebSecurity.RegisterGoogleClient”. Run the application. Once the application is running click on “Login”. You will see at the right side the option to login using a Google account, click on “Google”.  You will be asked for Google credentials. If your login is successful you'll see a message asking for your approval to give permission to your site to access your information. Click on “Accept”. Now a page to register your user will be shown, click on “Register”. Now your new user is logged in in your application. You can take a look of the user information created in the tables  UserProfile and Webpages_OauthMembership. If you want to use another external option to authenticate users you must enable the client in the same class where we enable the Google authentication, but for others providers is mandatory to register your Application in their site. Once you have register your application they will give you a token/key and the id for your application, that information you're going to use it to register the client. Thanks for reading.

• Will HTML5 make Silverlight redundant?

  - by Laila

  One of the great features of Adobe AIR v2 that was launched this month was its support for some of the 2008 draft of HTML5. The HTML5 specification was started in 2004, but the full spec will probably not be approved by W3C until around 2022. One might have thought that it would take years yet from now to reach the point where any browsers were remotely HTML5-compliant, but enough of HTML5 is published and agreed to make a lot of it possible, and Safari and Adobe have got there thanks to Apple's open-source WebKit. The race for HTML 5 has been fuelled by the demand by Apple and Google for advanced graphics, typography, animations and transitions without having to rely on third party browser plug-ins such as Adobe Flash or Silverlight. There is good reason for this haste: Flash doesn't support touch-devices and has been slow in supporting hardware video decoders such as H.264. There is a strong requirement to do all that Flash can do in an open-standards way. Those with proprietary solutions remain sniffy. In AIR 2, Adobe pointedly disables the HTML5 and tags that allow basic playing of media content, saying that the specification is not final and there is still no standard for the supported formats, and adding that Safari implements a 'disjoint set' of codecs. Microsoft also has little interest in HTML 5 as it has so much invested in Silverlight. Google stands to gain by the Adobe AIR for Android as it will allow a lot of applications to be migrated easily to the platform, so sees Apple's war on Flash as a way of gaining market share. Why do we care? It is because HTML5/CSS3 provides facilities much far beyond HTML4, bring the reality of browser-based applications a lot closer. Probably most generally useful is the advanced typography: Safari and AIR already both support a way of reflowing text in a container across an arbitrary number of columns; Page-specific fonts can also be specified. Then there is 2D drawing, video, transitions, local storage, AJAX navigation and mutable DOM prototypes. HTML5 is likely to provide base functionality that is required but it is too early to be certain that it will render Flash, Silverlight or JavaFX obsolete. In the meantime, Adobe Air provides the best vehicle for developing HTML5/CSS3 applications without a twinge of worry about browser incompatibilities. Cheers, Laila

• Oracle OpenWorld Call for MDM Papers

  - by david.butler(at)oracle.com

  As the MDM Track owner, I would like to invite everyone to respond to the Oracle OpenWorld (October 2-6, Moscone Center, San Francisco) Call for Papers (https://oracleus.wingateweb.com/portal/cfp/ ). The Call for Papers is open now through Sunday, March 27. This is an outstanding opportunity for organizations familiar with MDM to tell their story to a very large, knowledgeable and intensely interested community. Opportunities for feedback and networking abound.  I would love to see MDM papers on: business drivers; business benefits; quantified ROI stories; business process optimization; implementation styles; implementation lessons learned; using master data as a service; data governance best practices; end-to-end data quality experiences; support for SOA; Chart of Accounts issues fixed; how to leverage reference data; improving EPM and/or BI across the board; operationalizing a data warehouse; support for cloud computing; compliance success stories; architecture, scalability, and mixed workload RAC platform performance examples; industry specific value propositions (Financial Services; Retail, Telecom; Manufacturing, High Tech Manufacturing, Public Sector, Health Care, …); and line of business specific value propositions (CRM, ERP, PLM, SCM, …); etc. In fact, given that MDM positively impacts all areas of operations and analytics, there are no limits to the ideas you may have for an OpenWorld presentation. When you follow the submission process, be sure to use “Master Data Management” for either the Primary or Optional track. Add “Master Data Management” as an Optional track if you are adding MDM content to a presentation on one of the following tracks: Agile; Customer Relationship Management, Oracle E-Business Suite, Product Lifecycle Management, Siebel, Sourcing and Procurement, Supply Chain Management, or one of the 18 available industry tracks. If Cloud Computing is included, please add “Cloud Computing” as a Cross-Stream Track. And don’t forget to make “MDM” a Tag, along with Business Intelligence, Cloud, CRM, Data Integration, Data Migration, Data Warehousing, EPM, or Service-Oriented Architecture whenever your content includes these items. I will personally review each submission. I hope you all keep me very busy over the next few weeks.

• Releasing the new Sample Browser Phone app

  - by Jialiang

  Originally posted on: http://geekswithblogs.net/Jialiang/archive/2014/06/05/releasing-the-new-sample-browser-phone-app.aspx Starting its journey in 2010, Sample Browser is achieving its tetralogy by releasing a Windows Phone version Sample Browser today. The new Windows Phone app is the fourth milestone of Sample Browser since we released the desktop version and the Visual Studio version in 2012 and the Windows Store version in 2013. This time, by providing a sample browser designed for a ‘walking’ platform in response to MVPs’ suggestions during last year’s MVP Global Summit, we are literally putting a world of code samples "at developers’ fingertips”. If you like to have a code gallery of over 7000 quality code samples in your pocket, then click here to download our Windows Phone Sample Browser and start a fantastic mobile experience. With Windows Phone version Sample Browser and the Internet, you can search for code samples on MSDN at anytime and anywhere you want, 24/7 and–even to bed. You can also check code sample details and share them with your friends. Compared to the other 3 pieces in the tetralogy (desktop version, Visual Studio version, and the Windows Store version), the Windows Phone version Sample Browser sells itself for convenience and instant connectivity. For those who need to reach code samples under mobile circumstances where no PCs is available, Windows Phone version Sample Browser will definitely be the right service you are seeking for. Aside from sharing samples via emails as the other 3 do, the Windows Phone version Sample Browser also allows you to share the sample via SMS and Near Field Communication (NFC).   What's Next Currently, the Windows Phone Sample Browser only supports online MSDN code searching, but we already plan to upgrade Sample Browser to allow users to do ‘Bing code search’, and add and manage their private code snippets.  We will also upgrade the app to universal app. Universal App is a new concept brought up in the Microsoft Build Developer Conference 2014. It is a new development model that allows for a single app to be deployed across multiple Windows devices such as Windows Phone, Windows 8.1, and XBox. Therefore, once we finish upgrading Sample Browser to a universal app, you can synchronize your own code snippets across different devices; You can also mark a code sample as favorite on your Windows Phone and continue to study the sample when you are on your desktop. By then, sharing data between platforms will be a piece of cake. Also, the user experience of Sample Browser on different platforms will be more consistent.  The best is yet to come!   We sincerely suggest you give Sample Browser a try (click here to download). If you love what you see in Sample Browser, please recommend it to your friends and colleagues. If you encounter any problems or have any suggestions for us, please contact us at [email protected]. Your precious opinions and comments are more than welcome.

• Best way to remote restart Ubuntu from Windows machine

  - by robsoft

  Background: I'm looking to put a series of Ubuntu machines into retail locations, they're being used as dumb kiosks to show a series of slides onto large LCD panel TV screens. Once installed, they won't have a keyboard or mouse connected but will have a fixed IP on the local network. Everything is configured to auto-start, no automatic updates, no power saving etc - I think we're pretty-much good to go apart from one thing. I need the retail staff to be able to restart the boxes if a problem arises. We have VNC running (now that we've turned off desktop enhancements!) so that we can remotely get into the machines if we need to, but that's not something we would allow the retail staff to do. The machines are going to be physically 'out of the way' (probably in the ceiling space) so the power button is not easily accessible!. I'd like to have some means of allowing the retail staff to restart the Ubuntu machine, from the desktop of one of their Windows terminals. I don't really want to give them some kind of raw terminal access (the command line will frighten them!) and I don't want them to use VNC (as stated above). Ideally there would be an icon on the Windows desktop, they double-click it, reply to a simple 'are you sure?' prompt, and then the Ubuntu box is told to restart. The Windows side of that won't be a problem, we can write something using Delphi, Python & Qt4, whatever - it's the Ubuntu side of it I'm stuck with. Out of sight/view, could I have a Windows program open a terminal across the network and tell Ubuntu to restart? Is this what SSH could be used for (I have never set that kind of thing up). The Windows programming side isn't really an issue, it's just that I'm a total Ubuntu noob and don't know where to start from the platform point of view. The other thing we considered is also having the machine automatically restart itself at a set time each day (obviously out of store hours!). To me, that seems a bit unnecessary (though forcing a restart once a week/month might be worthwhile). Any thoughts or suggestions? Being able to restart the box on demand across the network is my prime requirement.

• A brief note for customers running SOA Suite on AIX platforms

  - by christian

  When running Oracle SOA Suite with IBM JVMs on the AIX platform, we have seen performance slowdowns and/or memory leaks. On occasion, we have even encountered some OutOfMemoryError conditions and the concomittant Java coredump. If you are experiencing this issue, the resolution may be to configure -Dsun.reflect.inflationThreshold=0 in your JVM startup parameters. https://www.ibm.com/developerworks/java/library/j-nativememory-aix/ contains a detailed discussion of the IBM AIX JVM memory model, but I will summarize my interpretation and understanding of it in the context of SOA Suite, below. Java ClassLoaders on IBM JVMs are allocated a native memory area into which they are anticipated to map such things as jars loaded from the filesystem. This is an excellent memory optimization, as the file can be loaded into memory once and then shared amongst many JVMs on the same host, allowing for excellent horizontal scalability on AIX hosts. However, Java ClassLoaders are not used exclusively for loading files from disk. A performance optimization by the Oracle Java language developers enables reflectively accessed data to optimize from a JNI call into Java bytecodes which are then amenable to hotspot optimizations, amongst other things. This performance optimization is called inflation, and it is executed by generating a sun.reflect.DelegatingClassLoader instance dynamically to inject the Java bytecode into the virtual machine. It is generally considered an excellent optimization. However, it interacts very negatively with the native memory area allocated by the IBM JVM, effectively locking out memory that could otherwise be used by the Java process. SOA Suite and WebLogic are both very large users of reflection code. They reflectively use many code paths in their operation, generating lots of DelegatingClassLoaders in normal operation. The IBM JVM slowdown and subsequent OutOfMemoryError are as a direct result of the Java memory consumed by the DelegatingClassLoader instances generated by SOA Suite and WebLogic. Java garbage collection runs more frequently to try and keep memory available, until it can no longer do so and throws OutOfMemoryError. The setting sun.reflect.inflationThreshold=0 disables this optimization entirely, never allowing the JVM to generate the optimized reflection code. IBM JVMs are susceptible to this issue primarily because all Java ClassLoaders have this native memory allocation, which is shared with the regular Java heap. Oracle JVMs don't automatically give all ClassLoaders a native memory area, and my understanding is that jar files are never mapped completely from shared memory in the same way as IBM does it. This results in different behaviour characteristics on IBM vs Oracle JVMs.

• Finding a new programming language for web development?

  - by Xeoncross

  I'm wondering if there are any un-biased resources that give good, specific overviews of programming languages and their intended goals. I would like to learn a new language, but visiting the sites of each language isn't working. Each one talks about how great it is without much mention of it's weaknesses or specific goals. Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. Python is a programming language that lets you work more quickly and integrate your systems more effectively. Having been a PHP developer for years, Vic Cherubini sums up my plight well: I knew PHP well, had my own framework, and could work quickly to get something up and running. I programmed like this throughout the MVC revolution. I got better and better jobs (read: better paying, better title) as a PHP developer, but all along the way realizing that the code I wrote on my own time was great, and the code I worked with at work was horrible. Like, worse than horrible. Atrocious. OS Commerce level bad. Having side projects kept me sane, because the code I worked with at work made me miserable. This is why I'm retiring from PHP for my side projects and new programming ventures. I'm spent with PHP. Exhausted, if you will. I've reached a level where I think I'm at the top with it as a language and if I don't move on to a new language soon, I'll be done completely with programming and I do not want that. Languages I've looked at include JavaScript (for node.js), Ruby, Python, & Erlang. I've even thought about Scala or C++. The problem is figuring out which ones are built to handle my needs the best. So where can I go to skip the hype and get real information about the maturity of a platform, the size of the community, and the strengths & weaknesses of that language. If I know these then picking a language to continue my web development should be easy.

• How to move a website and domain name without experiencing downtime for emails or site?

  - by user4842

  Okay, I have a pretty complex problem, so I'll get right to it. I'm a designer who built a new website for my client. Their old site is hosted at GoDaddy, as well as their email. Problem is, the guy who built the original site decided to put the original domain name and hosting under HIS personal GoDaddy account. Well, that turned out to be a bad move for several reasons. Here's how it's all tied together. The original domain name, www.domainoriginal.com, was actually purchased at Network Solutions. The original web designer pointed the nameservers from Network Solutions to his GoDaddy account, where the email and hosting is setup. The new domain name, www.domainnew.com, was purchased under a new and separate GoDaddy account belonging to the company, and the new website was built under a 3rd party platform (Big Commerce). So, the www.domainnew.com is already pointed to the new website using A records at new GoDaddy account. All is fine there. However, they still need www.domainoriginal.com to point to the NEW website as well. (The old one can simply be deleted, it is NOT important). AND, they want to keep their old email addresses intact and working as well, but under the NEW GoDaddy account. Obviously, I have no DNS control at Network Solutions, and I have no idea what kind of control I have at GoDaddy under the old account because the web designer will not let me see inside his account. But, he and GoDaddy both tell me nothing can be done other than to repoint the nameservers to Network Solutions, and then repoint the A record to my new website, www.domainnew.com, and point the MX Records to GoDaddy. I'm told the downtime would be 24-48 hours if I do this. Ideally, we'd like to do a domain name transfer and get www.domainoriginal.com in the new GoDaddy account created by the company. But, I'm told this could take up to 7 days. Does this mean the site and email will be down for 7 days? And any emails sent during this time, would they be lost forever? If I do this, how long could I expect the site and email to go down? And, will the emails be permanently lost? I've gotten different answers from everybody at GoDaddy so I kind of don't trust them anymore... Any help would be greatly appreciated Thanks, Tyson

• How to resolve concurrent ramp collisions in 2d platformer?

  - by Shaun Inman

  A bit about the physics engine: Bodies are all rectangles. Bodies are sorted at the beginning of every update loop based on the body-in-motion's horizontal and vertical velocity (to avoid sticky walls/floors). Solid bodies are resolved by testing the body-in-motion's new X with the old Y and adjusting if necessary before testing the new X with the new Y, again adjusting if necessary. Works great. Ramps (rectangles with a flag set indicating bottom-left, bottom-right, etc) are resolved by calculating the ratio of penetration along the x-axis and setting a new Y accordingly (with some checks to make sure the body-in-motion isn't attacking from the tall or flat side, in which case the ramp is treated as a normal rectangle). This also works great. Side-by-side ramps, eg. \/ and /\, work fine but things get jittery and unpredictable when a top-down ramp is directly above a bottom-up ramp, eg. < or > or when a bottom-up ramp runs right up to the ceiling/top-down ramp runs right down to the floor. I've been able to lock it down somewhat by detecting whether the body-in-motion hadFloor when also colliding with a top-down ramp or hadCeiling when also colliding with a bottom-up ramp then resolving by calculating the ratio of penetration along the y-axis and setting the new X accordingly (the opposite of the normal behavior). But as soon as the body-in-motion jumps the hasFloor flag becomes false, the first ramp resolution pushes the body into collision with the second ramp and collision resolution becomes jittery again for a few frames. I'm sure I'm making this more complicated than it needs to be. Can anyone recommend a good resource that outlines the best way to address this problem? (Please don't recommend I use something like Box2d or Chipmunk. Also, "redesign your levels" isn't an answer; the body-in-motion may at times be riding another body-in-motion, eg. a platform, that pushes it into a ramp so I'd like to be able to resolve this properly.) Thanks!

• Help with Collision of spawned object(postion fixed) with objects that there are translating on screen

  - by Amrutha

  Hey guys I am creating a game using Corona SDK and so coding it in Lua. So there are 2 separate functions, To translate the hit objects and change their color when they are tapped The link below is the code I am using to for the first function http://developer.anscamobile.com/sample-code/fishies Spawn objects that will hit the translating objects on collision. Alos on collision the spawned object disappears and the translating object bears a color(indicating the collision). In addition the size of this spawned object is dependent on i/p volume level. The function I have written is as follows: --VOICE INPUT CODE local r = media.newRecording() r:startRecording() r:startTuner() --local function newBar() -- local bar = display.newLine( 0, 0, 1, 0 ) -- bar:setColor( 0, 55, 100, 20 ) -- bar.width = 5 -- bar.y=400 -- bar.x=20 -- return bar --end local c1 = display.newImage("str-minion-small.png") c1.isVisible=false local c2 = display.newImage("str-minion-mid.png") c2.isVisible=false local c3 = display.newImage("str-minion-big.png") c3.isVisible=false --SPAWNING local function spawnDisk( event ) local phase = event.phase local volumeBar = display.newLine( 0, 0, 1, 0 ) volumeBar.y = 400 volumeBar.x = 20 --volumeBar.isVisible=false local v = 20*math.log(r:getTunerVolume()) local MINTHRESH = 30 local LEFTMARGIN = 20 local v2 = MINTHRESH + math.max (v, -MINTHRESH) v2 = (display.contentWidth - 1 * LEFTMARGIN ) * v2 / MINTHRESH volumeBar.xScale = math.max ( 20, v2 ) local l = volumeBar.xScale local cnt1 = 0 local cnt2 = 0 local cnt3 = 0 local ONE =1 local val = event.numTaps --local px=event.x --local py=event.y if "ended" == phase then --audio.play( popSound ) --myLabel.isVisible = false if l > 50 and l <=150 then --c1:setFillColor(10,105,0) --c1.isVisible=false c1.x=math.random( 10, 450 ) c1.y=math.random( 10, 300 ) physics.addBody( c1, { density=1, radius=10.0 } ) c1.isVisible=true cnt1= cnt1+ ONE return c1 elseif l > 100 and l <=250 then --c2:setFillColor(200,10,0) c2.x=math.random( 10, 450 ) c2.y=math.random( 10, 300 ) physics.addBody( c2, { density=2, radius=9000.0 } ) c2.isVisible=true cnt2= cnt2+ ONE return c2 elseif l >=250 then c3.x=math.random( 40, 450 ) c3.y=math.random( 40, 300 ) physics.addBody( c3, { density=2, radius=7000.0 , bounce=0.0 } ) c3.isVisible=true cnt3= cnt3+ ONE return c3 end end end buzzR:addEventListener( "touch", spawnDisk ) -- touch the screen to create disks Now both functions work fine independently but there is no collision happening. Its almost as if the translating object and the spawn object are on different layers. The translating object passes through the spawn object freely. Can anyone please tell me how to resolve this problem. And how can I get them to collide. Its my first attempt at game development, that too for a mobile platform so would appreciate all help. Also if I have not been specific do let me know. I'll try to frame the query better :). Thanks in advance.

• Application Integration Future &ndash; BizTalk Server &amp; Windows Azure (TechEd 2012)

  - by SURESH GIRIRAJAN

  I am really excited to see lot of new news around BizTalk in TechEd 2012. I was recently watching the session presented by Sriram and Rajesh on “Application Integration Futures: The Road Map and What's Next on Windows Azure”. It was great session and lot of interesting stuff about the feature updates for BizTalk and Azure integration. I have highlighted them below, definitely customers who haven’t started using Microsoft BizTalk ESB Toolkit should start using them which is going to be part of the core BizTalk product in future release, which is cool… BizTalk Server feature enhancements Manageability: ESB Tool Kit is going to be part of the core BizTalk product and Setup. Visualize BizTalk artifact dependencies in BizTalk administration console. HIS administration using configuration files. Performance: Improvements in ordered send port scenarios Improved performance in dynamic send ports and ESB, also to configure BizTalk host handler for dynamic send ports. Right now it runs under default host, which does not enable to scale. MLLP adapter enhancements and DB2 client transaction load balancing / client bulk insert. Platform Support: Visual Studio 2012, Windows 8 Server, SQL Server 2012, Office 15 and System Center 2012. B2B enhancements to support latest industry standards natively. Connectivity Improvements: Consume REST service directly in BizTalk SharePoint integration made easier. Improvements to SMTP adapter, to add macros for sending same email with different content to different parties. Connectivity to Azure Service Bus relay, queues and topics. DB2 client connectivity to SQL Server and SQL Server connectivity to Informix. CICS Http client connectivity to Windows. Azure: Use Azure as IaaS/PaaS for BizTalk environment. Use Azure to provision BizTalk environment for test environment / development. Later move to On-premises or build a Hybrid cloud approach. Eliminate HW procurement for BizTalk environment for testing / demos / development etc. Enable to create BizTalk farm easily and remove/add more servers as needed. EAI Service: EAI Bridge Protocol transformation Message Transformation Running custom code Message Enrichment Hybrid Connectivity LOB Applications On-premises Application On-premises Connectivity to Applications in the cloud Queues/ Topics Ftp Devices Web Services Bridge can be customized based on the service needs to provide different capabilities needed as part of the bridge. Look at the sample for EDI bridge for EDI service sample. Also with Tracking enabled through the portal. http://msdn.microsoft.com/en-us/library/windowsazure/hh674490 Adapters: Service Bus Messaging adapter - New adapter added. WebHttp adapter - For REST services. NetTcpRelay adapter - New adapter added. I will start posting more and once I start playing with this…

• 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
