  • When using membership provider, do you use the user ID or the username?

    - by Chris
    I've come across this is in a couple of different applications that I've worked on. They all used the ASP.NET Membership Provider for user accounts and controlling access to certain areas, but when we've gotten down into the code I've noticed that in one we're passing around the string based user name, like "Ralph Waters", or we're passing around the Guid based user ID from the membership table. Now both seem to work. You can make methods which get by username, or get by user ID, but both have felt somewhat "funny". When you pass a string like "Ralph Waters" you're passing essentially two separate words that make up a unique identifier. And with a Guid, you're passing around a string/number combination which can be cast and made unique. So my question is this; when using Membership Provider, which do you use, the username or the user ID to get back to the user? Thanks all!

  • Best way to block "comment spam" postings to web forms? [closed]

    - by David Jones
    Possible Duplicate: Make your site anti-bot? I have a custom web form on my PHP-based site. Recently it is getting a regular stream of comment-spam postings from a few specific IP addresses. Question: What is a good way to block a small set of blacklisted IP addresses from accessing my site? I was thinking it should be possible using .htaccess to respond with status code 403 (Forbidden) for all HTTP requests from the blacklisted IP addresses, ... but I am not sure exactly how to do that. If anyone knows the .htaccess syntax needed to accomplish this, ... please let me know. thanks in advance,

  • Building an Infrastructure Cloud with Oracle VM for x86 + Enterprise Manager 12c

    - by Richard Rotter
    Cloud Computing? Everyone is talking about Cloud these days. Everyone is explaining how the cloud will help you to bring your service up and running very fast, secure and with little effort. You can find these kinds of presentations at almost every event around the globe. But what is really behind all this stuff? Is it really so simple? And the answer is: Yes it is! With the Oracle SW Stack it is! In this post, I will try to bring this down to earth, demonstrating how easy it could be to build a cloud infrastructure with Oracle's solution for cloud computing.But let me cover some basics first: How fast can you build a cloud?How elastic is your cloud so you can provide new services on demand? How much effort does it take to monitor and operate your Cloud Infrastructure in order to meet your SLAs?How easy is it to chargeback for your services provided? These are the critical success factors of Cloud Computing. And Oracle has an answer to all those questions. By using Oracle VM for X86 in combination with Enterprise Manager 12c you can build and control your cloud environment very fast and easy. What are the fundamental building blocks for your cloud? Oracle Cloud Building Blocks #1 Hardware Surprise, surprise. Even the cloud needs to run somewhere, hence you will need hardware. This HW normally consists of servers, storage and networking. But Oracles goes beyond that. There are Optimized Solutions available for your cloud infrastructure. This is a cookbook to build your HW cloud platform. For example, building your cloud infrastructure with blades and our network infrastructure will reduce complexity in your datacenter (Blades with switch network modules, splitter cables to reduce the amount of cables, TOR (Top Of the Rack) switches which are building the interface to your infrastructure environment. Reducing complexity even in the cabling will help you to manage your environment more efficient and with less risk. Of course, our engineered systems fit into the cloud perfectly too. Although they are considered as a PaaS themselves, having the database SW (for Exadata) and the application development environment (for Exalogic) already deployed on them, in general they are ideal systems to enable you building your own cloud and PaaS infrastructure. #2 Virtualization The next missing link in the cloud setup is virtualization. For me personally, it's one of the most hidden "secret", that oracle can provide you with a complete virtualization stack in terms of a hypervisor on both architectures: X86 and Sparc CPUs. There is Oracle VM for X86 and Oracle VM for Sparc available at no additional  license costs if your are running this virtualization stack on top of Oracle HW (and with Oracle Premier Support for HW). This completes the virtualization portfolio together with Solaris Zones introduced already with Solaris 10 a few years ago. Let me explain how Oracle VM for X86 works: Oracle VM for x86 consists of two main parts: - The Oracle VM Server: Oracle VM Server is installed on bare metal and it is the hypervisor which is able to run virtual machines. It has a very small footprint. The ISO-Image of Oracle VM Server is only 200MB large. It is very small but efficient. You can install a OVM-Server in less than 5 mins by booting the Server with the ISO-Image assigned and providing the necessary configuration parameters (like installing an Linux distribution). After the installation, the OVM-Server is ready to use. That's all. - The Oracle VM-Manager: OVM-Manager is the central management tool where you can control your OVM-Servers. OVM-Manager provides the graphical user interface, which is an Application Development Framework (ADF) application, with a familiar web-browser based interface, to manage Oracle VM Servers, virtual machines, and resources. The Oracle VM Manager has the following capabilities: Create virtual machines Create server pools Power on and off virtual machines Manage networks and storage Import virtual machines, ISO files, and templates Manage high availability of Oracle VM Servers, server pools, and virtual machines Perform live migration of virtual machines I want to highlight one of the goodies which you can use if you are running Oracle VM for X86: Preconfigured, downloadable Virtual Machine Templates form edelivery With these templates, you can download completely preconfigured Virtual Machines in your environment, boot them up, configure them at first time boot and use it. There are templates for almost all Oracle SW and Applications (like Fusion Middleware, Database, Siebel, etc.) available. #3) Cloud Management The management of your cloud infrastructure is key. This is a day-to-day job. Acquiring HW, installing a virtualization layer on top of it is done just at the beginning and if you want to expand your infrastructure. But managing your cloud, keeping it up and running, deploying new services, changing your chargeback model, etc, these are the daily jobs. These jobs must be simple, secure and easy to manage. The Enterprise Manager 12c Cloud provides this functionality from one management cockpit. Enterprise Manager 12c uses Oracle VM Manager to control OVM Serverpools. Once you registered your OVM-Managers in Enterprise Manager, then you are able to setup your cloud infrastructure and manage everything from Enterprise Manager. What you need to do in EM12c is: ">Register your OVM Manager in Enterprise ManagerAfter Registering your OVM Manager, all the functionality of Oracle VM for X86 is also available in Enterprise Manager. Enterprise Manager works as a "Manger" of the Manager. You can register as many OVM-Managers you want and control your complete virtualization environment Create Roles and Users for your Self Service Portal in Enterprise ManagerWith this step you allow users to logon on the Enterprise Manager Self Service Portal. Users can request Virtual Machines in this portal. Setup the Cloud InfrastructureSetup the Quotas for your self service users. How many VMs can they request? How much of your resources ( cpu, memory, storage, network, etc. etc.)? Which SW components (templates, assemblys) can your self service users request? In this step, you basically set up the complete cloud infrastructure. Setup ChargebackOnce your cloud is set up, you need to configure your chargeback mechanism. The Enterprise Manager collects the resources metrics, which are used in a very deep level. Almost all collected Metrics could be used in the chargeback module. You can define chargeback plans based on configurations (charge for the amount of cpu, memory, storage is assigned to a machine, or for a specific OS which is installed) or chargeback on resource consumption (% of cpu used, storage used, etc). Or you can also define a combination of configuration and consumption chargeback plans. The chargeback module is very flexible. Here is a overview of the workflow how to handle infrastructure cloud in EM: Summary As you can see, setting up an Infrastructure Cloud Service with Oracle VM for X86 and Enterprise Manager 12c is really simple. I personally configured a complete cloud environment with three X86 servers and a small JBOD san box in less than 3 hours. There is no magic in it, it is all straightforward. Of course, you have to have some experience with Oracle VM and Enterprise Manager. Experience in setting up Linux environments helps as well. I plan to publish a technical cookbook in the next few weeks. I hope you found this post useful and will see you again here on our blog. Any hints, comments are welcome!

  • Embed Unity3D and load multiple games from a single app

    - by Rafael Steil
    Is is possible to export an entire unity3d project/game as an AssetBundle and load it on iOS/Android/Windows on an app that doesn't know anything about such game beforehand? What I have in mind is something like the web plugin does - it loads a series of .unity3d files over http, and render inline in the browser window. Is it even possible to do something closer for iOS/Android? I have read a lot of docs so far, but still can't be sure: http://floored.com/blog/2013/integrating-unity3d-within-ios-native-application.html http://docs.unity3d.com/Manual/LoadingResourcesatRuntime.html http://docs.unity3d.com/Manual/AssetBundlesIntro.html The code from the post at http://forum.unity3d.com/threads/112703-Override-Unity-Data-folder-path?p=749108&viewfull=1#post749108 works for Android, but how about iOS and other platforms?

  • creating a pre-menu level select screen

    - by Ephiras
    Hi I am working on creating a tower Defence java applet game and have come to a road block about implementing a title screen that i can select the level and difficulty of the rest of the game. my title screen class is called Menu. from this menu class i need to pass in many different variables into my Main class. i have used different classes before and know how to run them and such. but if both classes extend applet and each has its individual graphics method how can i run things from Main even though it was created in Menu. what i essentially want to do is run the Menu class withits action listeners and graphics until a Difficulty button has been selected, run the main class (which 100% works without having to have the Menu class) and pretty much terminate Menu so that i cannot go back to it, do not see its buttons or graphics menus. can i run one applet annd when i choose a button close that one and launch the other one? IF you would like to download the full project you can find it here, i had to comment out all the code that wasn't working my Menu class import java.awt.*; import java.awt.event.*; import java.applet.*; public class Menu extends Applet implements ActionListener{ Button bEasy,bMed,bHard; Main m; public void init(){ bEasy= new Button("Easy"); bEasy.setBounds(140,200,100,50); add(bEasy); bMed = new Button("Medium");bMed.setBounds(280,200,100,50); add(bMed); bHard= new Button("Hard");bHard.setBounds(420,200,100,50); add(bHard); setLayout(null); } public void actionPerformed(ActionEvent e){ Main m = new Main(20,10,3000,mapMed);//break; switch (e.getSource()){ case bEasy: Main m = new Main(6000,20,"levels/levelEasy.png");break;//enimies tower money world case bMed: Main m = new Main(4000,15,"levels/levelMed.png");break; case bHard: Main m = new Main(2000,10,"levels/levelEasy.png");break; default: break; } } public void paint(){ //m.draw(g) } } and here is my main class initialising code. import java.awt.*; import java.awt.event.*; import java.applet.*; import java.io.IOException; public class Main extends Applet implements Runnable, MouseListener, MouseMotionListener, ActionListener{ Button startButton, UpgRange, UpgDamage; //set up the buttons Color roadCol,startCol,finCol,selGrass,selRoad; //set up the colors Enemy e[][]; Tower t[]; Image towerpic,backpic,roadpic,levelPic; private Image i; private Graphics doubleG; //here is the world 0=grass 1=road 2=start 3=end int world[][],eStartX,eStartY; boolean drawMouse,gameEnd; static boolean start=false; static int gridLength=15; static int round=0; int Mx,My,timer=1500; static int sqrSize=31; int towers=0,towerSelected=-10; static int castleHealth=2000; String levelPath; //choose the level Easy Med or Hard int maxEnemy[] = {5,7,12,20,30,15,50,30,40,60};//number of enimies per round int maxTowers=15;//maximum number of towers allowed static int money =2000,damPrice=600,ranPrice=350,towerPrice=700; //money = the intial ammount of money you start of with //damPrice is the price to increase the damage of a tower //ranPrice is the price to increase the range of a tower public void main(int cH,int mT,int mo,int dP,int rP,int tP,String path,int[] mE)//constructor 1 castleHealth=cH; maxTowers=mT; money=mo; damPrice=dP; ranPrice=rP; towerPrice=tP; String levelPath=path; maxEnemy = mE; buildLevel(); } public void main(int cH,int mT,String path)//basic constructor castleHealth=cH; maxTowers=mT; String levelPath=path; maxEnemy = mE; buildLevel(); } public void init(){ setSize(sqrSize*15+200,sqrSize*15);//set the size of the screen roadCol = new Color(255,216,0);//set the colors for the different objects startCol = new Color(0,38,255); finCol = new Color(255,0,0); selRoad = new Color(242,204,155);//selColor is the color of something when your mouse hovers over it selGrass = new Color(0,190,0); roadpic = getImage(getDocumentBase(),"images/road.jpg"); towerpic = getImage(getDocumentBase(),"images/tower.png"); backpic = getImage(getDocumentBase(),"images/grass.jpg"); levelPic = getImage(getDocumentBase(),"images/level.jpg"); e= new Enemy[maxEnemy.length][];//activates all of the enimies for (int r=0;r<e.length;r++) e[r] = new Enemy[maxEnemy[r]]; t= new Tower[maxTowers]; for (int i=0;i<t.length;i++) t[i]= new Tower();//activates all the towers for (int i=0;i<e.length; i++)//sets all of the enimies starting co ordinates for (int j=0;j<e[i].length;j++) e[i][j] = new Enemy(eStartX,eStartY,world); initButtons();//initialise all the buttons addMouseMotionListener(this); addMouseListener(this); }

  • Which programming language to develop software for USC that also runs on other OS?? (WINDOWS/OSX)

    - by Marian Lux
    I have skills in JAVA and C#: First i had a closer look to JAVA (Eclipse with Windowbuilder-Plugin) - Swing: But there is no natvie GUI-Support for GTK3 (e.g., HUD seems not to work) Then i was at JAVA - SWT: It is to heavy. I want do code a small app that improves the Ubuntu desktop. I don't want to ship a program with eclipse included. After that i found C# Mono (Monodevelop): GTK-shparp is only for GTK2 available. A GTK3-port will come soon but is it possible to convert the program from GTK2 to GTK3 without extra adaptations? The next bad thing is, that MONO is now dropped from Ubuntu LTS 12.04. So i have no chance that my app would be a default-app in an Ubuntu-Image. (This is also a factor for me to choose a programming language). I know there are other techs but i want to use as programing language JAVA or C#.

  • How do you learn a new programming language?

    - by Naveen
    I am C++ developer with some good experience on it. When I try to learn a new language ( have tried Java, C#, python, perl till now) I usually pickup a book and try to read it. But the problem with this is that these books typically start with some very basic programming concepts such as loops, operators etc and it starts to get very boring soon. Also, I feel I would get only theoeritcal knowledge without any practical knowledge on writing the code. So my question is how do you tacke these situations? do you just skip the chapters if its explaining something basic? also, do you have some standard set of programs that you will try to write in every new programming language you try to learn?

  • Why won't title attributes get indexed in Google?

    - by Sam
    When I search for Ride On + my site's name, I see that it's indexed. But when I search for Green Horse + my site's name, I don't see my site appearing in the results anywhere! Here's my code: <td><a href="#" title="Green Horse Ride">Ride On</a></td> Does this mean that title attributes are not indexed/shown by Google at all? What is better to use, alt? What are the other alternatives except title and alt?

  • XNA Diffuse Shader Issue. Edge lighting problem. Image Attached

    - by adtither
    As you can see in this image the diffuse shading is working correctly in some places but in other places such as the the bottom of the sphere you can see the squares/triangles of the mesh. Any idea what would be causing this? Let me know if you need anymore information related to code. I can upload my normals calculations and shader effect if required. EDIT: Here's a link to the shader I'm using http://pastebin.com/gymVc7CP Link to normals calculations: http://pastebin.com/KnMGdzHP Seems to be an issue with edge lighting. Can't seem to see where I'm going wrong with the normals calculations though.

  • Paying a developer in stock/fixed rate? [closed]

    - by user51648
    I have an idea for a cross platform application. It will require knowledge of several different languages, web development, and system administration/IT. I don't personally code, but I want to pay professionals to do it. I'm wondering how I should go about paying them. Yes, this will be a large project, but I want it done ASAP. Is it ok if I don't pay them by the hour? I really want it to be a set price. Also, is it reasonable to pay them in stock of the company? Like, 20%? P.S. How do I know how big a project will be in order to give the devs themselves an idea?

  • Prefer algorithms to hand-written loops?

    - by FredOverflow
    Which of the following to you find more readable? The hand-written loop: for (std::vector<Foo>::const_iterator it = vec.begin(); it != vec.end(); ++it) { bar.process(*it); } Or the algorithm invocation: #include <algorithm> #include <functional> std::for_each(vec.begin(), vec.end(), std::bind1st(std::mem_fun_ref(&Bar::process), bar)); I wonder if std::for_each is really worth it, given such a simple example already requires so much code. What are your thoughts on this matter?

  • How do I install third-party rhythmbox plugins?

    - by fossfreedom
    Now that the dust has settled and Rhythmbox has become (again) the default music-media player in 12.04, I'm interested in extending its functionality. For example, the default lyric plugin does not work for me and there doesn't appear to be an sound-equalizer by default. Having done a search, I came across the Gnome-website that lists a number of third-party plugins, some-of which I wish to install which can resolve the above. However, there doesn't appear to be .deb packages or a repository containing these plugins. Instead there are links to source-code websites such as GitHub and others. So, I'm confused - I don't know which plugins works in 12.04 Rhythmbox and I'm not sure how to install these. Help please?

  • Getting that buzz back?

    - by kyndigs
    I have been working in development for a good company for a while now since graduating from university, I really enjoy it and have some great fun in the office and enjoy everything I am doing. But recently I have lost that old buzz, I cant bring myself to code outside of work, a while back I could be outside of work and come up with a nice idea and go away and develop that idea, but I feel that buzz has gone, I still love developing and technology but I just cant find the energy to do it when I am not at work. Has anyone else gone through a phase like this? What did you do to combat it and get that energy and buzz back? Maybe I need a new tehcnology, or a holiday!

  • GLSL: Strange light reflections [Solved]

    - by Tom
    According to this tutorial I'm trying to make a normal mapping using GLSL, but something is wrong and I can't find the solution. The output render is in this image: Image1 in this image is a plane with two triangles and each of it is different illuminated (that is bad). The plane has 6 vertices. In the upper left side of this plane are 2 identical vertices (same in the lower right). Here are some vectors same for each vertice: normal vector = 0, 1, 0 (red lines on image) tangent vector = 0, 0,-1 (green lines on image) bitangent vector = -1, 0, 0 (blue lines on image) here I have one question: The two identical vertices does need to have the same tangent and bitangent? I have tried to make other values to the tangents but the effect was still similar. Here are my shaders Vertex shader: #version 130 // Input vertex data, different for all executions of this shader. in vec3 vertexPosition_modelspace; in vec2 vertexUV; in vec3 vertexNormal_modelspace; in vec3 vertexTangent_modelspace; in vec3 vertexBitangent_modelspace; // Output data ; will be interpolated for each fragment. out vec2 UV; out vec3 Position_worldspace; out vec3 EyeDirection_cameraspace; out vec3 LightDirection_cameraspace; out vec3 LightDirection_tangentspace; out vec3 EyeDirection_tangentspace; // Values that stay constant for the whole mesh. uniform mat4 MVP; uniform mat4 V; uniform mat4 M; uniform mat3 MV3x3; uniform vec3 LightPosition_worldspace; void main(){ // Output position of the vertex, in clip space : MVP * position gl_Position = MVP * vec4(vertexPosition_modelspace,1); // Position of the vertex, in worldspace : M * position Position_worldspace = (M * vec4(vertexPosition_modelspace,1)).xyz; // Vector that goes from the vertex to the camera, in camera space. // In camera space, the camera is at the origin (0,0,0). vec3 vertexPosition_cameraspace = ( V * M * vec4(vertexPosition_modelspace,1)).xyz; EyeDirection_cameraspace = vec3(0,0,0) - vertexPosition_cameraspace; // Vector that goes from the vertex to the light, in camera space. M is ommited because it's identity. vec3 LightPosition_cameraspace = ( V * vec4(LightPosition_worldspace,1)).xyz; LightDirection_cameraspace = LightPosition_cameraspace + EyeDirection_cameraspace; // UV of the vertex. No special space for this one.

  • Chambers In A Castle Algorithm

    - by 7Aces
    Problem Statement - Given a NxM grid of 1s & 0s (1s mark walls, while 0s indicate empty chambers), the task is to identify the number of chambers & the size of the largest. And just to whet my curiosity, to find in which chamber, a cell belongs. It seems like an ad hoc problem, since the regular algorithms just don't fit in. I just can't get the logic for writing an algorithm for the problem. If you get it, pseudo-code would be of great help! Note - I have tried the regular grid search algorithms, but they don't suffice the problem requirements. Source - INOI Q Paper 2003

  • T-SQL User-Defined Functions: the good, the bad, and the ugly (part 1)

    - by Hugo Kornelis
    So you thought that encapsulating code in user-defined functions for easy reuse is a good idea? Think again! SQL Server supports three types of user-defined functions. Only one of them qualifies as good. The other two – well, the title says it all, doesn’t it? The bad: scalar functions A scalar user-defined function (UDF) is very much like a stored procedure, except that it always returns a single value of a predefined data type – and because of that property, it isn’t invoked with an EXECUTE statement,...(read more)

  • Can static and dynamically typed languages be seen as different tools for different types of jobs?

    - by Erik Reppen
    Yes, similar questions have been asked but always with the aim of finding out 'which one is better.' I'm asking because I came up as a dev primarily in JavaScript and don't really have any extensive experience writing in statically typed languages. In spite of this I definitely see value in learning C for handling demanding operations at lower levels of code (which I assume has a lot to do with static vs dynamic at the compiler level), but what I'm trying to wrap my head around is whether there are specific project contexts (maybe certain types of dynamic data-intensive operations?) involving things other than performance where it makes a lot more sense to go with Java or C# vs. something like Python.

  • Naming a predicate: "precondition" or "precondition_is_met"?

    - by RexE
    In my web app framework, each page can have a precondition that needs to be satisfied before it can be displayed to the user. For example, if user 1 and user 2 are playing a back-and-forth role-playing game, user 2 needs to wait for user 1 to finish his turn before he can take his turn. Otherwise, the user is displayed a waiting page. This is implemented with a predicate: def precondition(self): return user_1.completed_turn The simplest name for this API is precondition, but this leads to code like if precondition(): ..., which is not really obvious. Seems to me like it is more accurate to call it precondition_is_met(), but not sure about that either. Is there a best practice for naming methods like this?

  • WWDC 2012 announced features on iOS 5?

    - by Arnold Sakhnov
    I am relatively new to iOS development, so after watching a bunch of WWDC videos announcing new awesome features for the iPhone SDK, I still got a few questions regarding their support for older devices. Specifically: Do the new compiler features (such as literals support, auto-synthesize, etc) require iOS 6 on the target device, or can the new style code be deployed to iOS 5 devices? Auto-layout for iOS, same question. Will it only be supported on iOS 6, or 5 as well? If it's 6 only, what kind of fallback are we expected to implement? Would really appreciate if someone could clarify this for me, as I'm thinking about rewriting my older unfinished project and I would love to use some of that improved SDK functionality.

  • Lack of ideas for startup equals slack career?

    After 12-15 years of working in the same industry, if a person does not have any new ideas for a startup then is it safe to say that his/her career has not reached its potential? We are not talking of implementation strategies or insights here to fructify the startup -- just great ideas which can change things for the better. Not your source code optimization. I mean a radical way of looking at things. If you lot disagree with this line of thinking, then please share some examples where despite such a long span a person can end up without new ideas.

  • Why is my google translate data not showing up in analytics?

    - by learnvst
    I have a google translate widget on my website with gaTrack set to true and the correct gaId, but no translate events show up in analytics under content Events Overview after a week of the widget being live. The code snippet below was auto generated by the translate website, and works fine on the site. Any ideas why I'm not getting any translate events data? <li> <div id="google_translate_element"></div><script type="text/javascript"> function googleTranslateElementInit() { new google.translate.TranslateElement({pageLanguage: 'en', layout: google.translate.TranslateElement.InlineLayout.SIMPLE, gaTrack: true, gaId: 'UA-blahblah'}, 'google_translate_element'); } </script><script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script> </li>

  • I need recommendations on free, open source, PHP-based business intelligence widget frameworks [on hold]

    - by Volomike
    I'm a PHP developer on Linux, and my manager wants a business intelligence dashboard. He wants to see in real-time our profit/loss stuff in fancy charts, based on our software sales. I could code it all from scratch and use Google Charts API or some other charts API to help me. However, I wanted to know if there was a free, open source, PHP-based business intelligence package out there, or some sort of widget framework that I could start with. That way, I can build the BI widgets inside that framework and not have to do everything from scratch. I apologize ahead of time if this is the wrong stackexchange where to place this query. I don't know where to place this query, and do want to follow the rules.

  • Stop map from scrolling but let player still move?

    - by ChocoMan
    I have a basic method of scrolling around on a map (moving the map instead of the player), but at when the player gets to a certain proximity to the edge, how do you stop the map from scrolling, but still allow the player to move around until it is away from that proximity? I'm not looking for any code. Just a suggestion so that I can implement it myself. I can see it visually (creating 4 boxed intersecting boundaries for the player to enter), but not sure how to come about stopping and resuming the scrolling of the map.
