• LexisNexis and Oracle Join Forces to Prevent Fraud and Identity Abuse

  - by Tanu Sood

  Author: Mark Karlstrand About the Writer:Mark Karlstrand is a Senior Product Manager at Oracle focused on innovative security for enterprise web and mobile applications. Over the last sixteen years Mark has served as director in a number of tech startups before joining Oracle in 2007. Working with a team of talented architects and engineers Mark developed Oracle Adaptive Access Manager, a best of breed access security solution.The world’s top enterprise software company and the world leader in data driven solutions have teamed up to provide a new integrated security solution to prevent fraud and misuse of identities. LexisNexis Risk Solutions, a Gold level member of Oracle PartnerNetwork (OPN), today announced it has achieved Oracle Validated Integration of its Instant Authenticate product with Oracle Identity Management.Oracle provides the most complete Identity and Access Management platform. The only identity management provider to offer advanced capabilities including device fingerprinting, location intelligence, real-time risk analysis, context-aware authentication and authorization makes the Oracle offering unique in the industry. LexisNexis Risk Solutions provides the industry leading Instant Authenticate dynamic knowledge based authentication (KBA) service which offers customers a secure and cost effective means to authenticate new user or prove authentication for password resets, lockouts and such scenarios. Oracle and LexisNexis now offer an integrated solution that combines the power of the most advanced identity management platform and superior data driven user authentication to stop identity fraud in its tracks and, in turn, offer significant operational cost savings. The solution offers the ability to challenge users with dynamic knowledge based authentication based on the risk of an access request or transaction thereby offering an additional level to other authentication methods such as static challenge questions or one-time password when needed. For example, with Oracle Identity Management self-service, the forgotten password reset workflow utilizes advanced capabilities including device fingerprinting, location intelligence, risk analysis and one-time password (OTP) via short message service (SMS) to secure this sensitive flow. Even when a user has lost or misplaced his/her mobile phone and, therefore, cannot receive the SMS, the new integrated solution eliminates the need to contact the help desk. The Oracle Identity Management platform dynamically switches to use the LexisNexis Instant Authenticate service for authentication if the user is not able to authenticate via OTP. The advanced Oracle and LexisNexis integrated solution, thus, both improves user experience and saves money by avoiding unnecessary help desk calls. Oracle Identity and Access Management secures applications, Juniper SSL VPN and other web resources with a thoroughly modern layered and context-aware platform. Users don't gain access just because they happen to have a valid username and password. An enterprise utilizing the Oracle solution has the ability to predicate access based on the specific context of the current situation. The device, location, temporal data, and any number of other attributes are evaluated in real-time to determine the specific risk at that moment. If the risk is elevated a user can be challenged for additional authentication, refused access or allowed access with limited privileges. The LexisNexis Instant Authenticate dynamic KBA service plugs into the Oracle platform to provide an additional layer of security by validating a user's identity in high risk access or transactions. The large and varied pool of data the LexisNexis solution utilizes to quiz a user makes this challenge mechanism even more robust. This strong combination of Oracle and LexisNexis user authentication capabilities greatly mitigates the risk of exposing sensitive applications and services on the Internet which helps an enterprise grow their business with confidence.Resources:Press release: LexisNexis® Achieves Oracle Validated Integration with Oracle Identity Management Oracle Access Management (HTML)Oracle Adaptive Access Manager (pdf)

• The Best Data Integration for Exadata Comes from Oracle

  - by maria costanzo

  Oracle Data Integrator and Oracle GoldenGate offer unique and optimized data integration solutions for Oracle Exadata. For example, customers that choose to feed their data warehouse or reporting database with near real-time throughout the day, can do so without decreasing  performance or availability of source and target systems. And if you ask why real-time, the short answer is: in today’s fast-paced, always-on world, business decisions need to use more relevant, timely data to be able to act fast and seize opportunities. A longer response to "why real-time" question can be found in a related blog post. If we look at the solution architecture, as shown on the diagram below,  Oracle Data Integrator and Oracle GoldenGate are both uniquely designed to take full advantage of the power of the database and to eliminate unnecessary middle-tier components. Oracle Data Integrator (ODI) is the best bulk data loading solution for Exadata. ODI is the only ETL platform that can leverage the full power of Exadata, integrate directly on the Exadata machine without any additional hardware, and by far provides the simplest setup and fastest overall performance on an Exadata system. We regularly see customers achieving a 5-10 times boost when they move their ETL to ODI on Exadata. For  some companies the performance gain is even much higher. For example a large insurance company did a proof of concept comparing ODI vs a traditional ETL tool (one of the market leaders) on Exadata. The same process that was taking 5hrs and 11 minutes to complete using the competing ETL product took 7 minutes and 20 seconds with ODI. Oracle Data Integrator was 42 times faster than the conventional ETL when running on Exadata.This shows that Oracle's own data integration offering helps you to gain the most out of your Exadata investment with a truly optimized solution. GoldenGate is the best solution for streaming data from heterogeneous sources into Exadata in real time. Oracle GoldenGate can also be used together with Data Integrator for hybrid use cases that also demand non-invasive capture, high-speed real time replication. Oracle GoldenGate enables real-time data feeds from heterogeneous sources non-invasively, and delivers to the staging area on the target Exadata system. ODI runs directly on Exadata to use the database engine power to perform in-database transformations. Enterprise Data Quality is integrated with Oracle Data integrator and enables ODI to load trusted data into the data warehouse tables. Only Oracle can offer all these technical benefits wrapped into a single intelligence data warehouse solution that runs on Exadata. Compared to traditional ETL with add-on CDC this solution offers: §  Non-invasive data capture from heterogeneous sources and avoids any performance impact on source §  No mid-tier; set based transformations use database power §  Mini-batches throughout the day –or- bulk processing nightly which means maximum availability for the DW §  Integrated solution with Enterprise Data Quality enables leveraging trusted data in the data warehouse In addition to Starwood Hotels and Resorts, Morrison Supermarkets, United Kingdom’s fourth-largest food retailer, has seen the power of this solution for their new BI platform and shared their story with us. Morrisons needed to analyze data across a large number of manufacturing, warehousing, retail, and financial applications with the goal to achieve single view into operations for improved customer service. The retailer deployed Oracle GoldenGate and Oracle Data Integrator to bring new data into Oracle Exadata in near real-time and replicate the data into reporting structures within the data warehouse—extending visibility into operations. Using Oracle's data integration offering for Exadata, Morrisons produced financial reports in seconds, rather than minutes, and improved staff productivity and agility. You can read more about Morrison’s success story here and hear from Starwood here. From an Irem Radzik article.

• Visual Studio Load Testing using Windows Azure

  - by Tarun Arora

  In my opinion the biggest adoption barrier in performance testing on smaller projects is not the tooling but the high infrastructure and administration cost that comes with this phase of testing. Only if a reusable solution was possible and infrastructure management wasn’t as expensive, adoption would certainly spike. It certainly is possible if you bring Visual Studio and Windows Azure into the equation. It is possible to run your test rig in the cloud without getting tangled in SCVMM or Lab Management. All you need is an active Azure subscription, Windows Azure endpoint enabled developer workstation running visual studio ultimate on premise, windows azure endpoint enabled worker roles on azure compute instances set up to run as test controllers and test agents. My test rig is running SQL server 2012 and Visual Studio 2012 RC agents. The beauty is that the solution is reusable, you can open the azure project, change the subscription and certificate, click publish and *BOOM* in less than 15 minutes you could have your own test rig running in the cloud. In this blog post I intend to show you how you can use the power of Windows Azure to effectively abstract the administration cost of infrastructure management and lower the total cost of Load & Performance Testing. As a bonus, I will share a reusable solution that you can use to automate test rig creation for both VS 2010 agents as well as VS 2012 agents. Introduction The slide show below should help you under the high level details of what we are trying to achive... Leveraging Azure for Performance Testing View more PowerPoint from Avanade Scenario 1 – Running a Test Rig in Windows Azure To start off with the basics, in the first scenario I plan to discuss how to, - Automate deployment & configuration of Windows Azure Worker Roles for Test Controller and Test Agent - Automate deployment & configuration of SQL database on Test Controller on the Test Controller Worker Role - Scaling Test Agents on demand - Creating a Web Performance Test and a simple Load Test - Managing Test Controllers right from Visual Studio on Premise Developer Workstation - Viewing results of the Load Test - Cleaning up - Have the above work in the shape of a reusable solution for both VS2010 and VS2012 Test Rig Scenario 2 – The scaled out Test Rig and sharing data using SQL Azure A scaled out version of this implementation would involve running multiple test rigs running in the cloud, in this scenario I will show you how to sync the load test database from these distributed test rigs into one SQL Azure database using Azure sync. The selling point for this scenario is being able to collate the load test efforts from across the organization into one data store. - Deploy multiple test rigs using the reusable solution from scenario 1 - Set up and configure Windows Azure Sync - Test SQL Azure Load Test result database created as a result of Windows Azure Sync - Cleaning up - Have the above work in the shape of a reusable solution for both VS2010 and VS2012 Test Rig The Ingredients Though with an active MSDN ultimate subscription you would already have access to everything and more, you will essentially need the below to try out the scenarios, 1. Windows Azure Subscription 2. Windows Azure Storage – Blob Storage 3. Windows Azure Compute – Worker Role 4. SQL Azure Database 5. SQL Data Sync 6. Windows Azure Connect – End points 7. SQL 2012 Express or SQL 2008 R2 Express 8. Visual Studio All Agents 2012 or Visual Studio All Agents 2010 9. A developer workstation set up with Visual Studio 2012 – Ultimate or Visual Studio 2010 – Ultimate 10. Visual Studio Load Test Unlimited Virtual User Pack. Walkthrough To set up the test rig in the cloud, the test controller, test agent and SQL express installers need to be available when the worker role set up starts, the easiest and most efficient way is to pre upload the required software into Windows Azure Blob storage. SQL express, test controller and test agent expose various switches which we can take advantage of including the quiet install switch. Once all the 3 have been installed the test controller needs to be registered with the test agents and the SQL database needs to be associated to the test controller. By enabling Windows Azure connect on the machines in the cloud and the developer workstation on premise we successfully create a virtual network amongst the machines enabling 2 way communication. All of the above can be done programmatically, let’s see step by step how… Scenario 1 Video Walkthrough–Leveraging Windows Azure for performance Testing Scenario 2 Work in progress, watch this space for more… Solution If you are still reading and are interested in the solution, drop me an email with your windows live id. I’ll add you to my TFS preview project which has a re-usable solution for both VS 2010 and VS 2012 test rigs as well as guidance and demo performance tests.   Conclusion Other posts and resources available here. Possibilities…. Endless!

• Getting App.config to be configuration specific in VS2010

  - by MarkPearl

  I recently wanted to have a console application that had configuration specific settings. For instance, if I had two configurations “Debug” and “Release”, depending on the currently selected configuration I wanted it to use a specific configuration file (either debug or config). If you are wanting to do something similar, here is a potential solution that worked for me. Setting up a demo app to illustrate the point First, let’s set up an application that will demonstrate the most basic concept. using System; using System.Configuration; namespace ConsoleSpecificConfiguration { class Program { static void Main(string[] args) { Console.WriteLine("Config"); Console.WriteLine(ConfigurationManager.AppSettings["Example Config"]); Console.ReadLine(); } } }   This does a really simple thing. Display a config when run. To do this, you also need a config file set up. My default looks as follows… <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="Example Config" value="Default"/> </appSettings> </configuration>   Your entire solution will look as follows… Running the project you will get the following amazing output…   Let’s now say instead of having one config file we want depending on whether we are running in “Debug” or “Release” for the solution configuration we want different config settings to be propagated across you can do the following… Step 1 – Create alternate config Files First add additional config files to your solution. You should have some form of naming convention for these config files, I have decided to follow a similar convention to the one used for web.config, so in my instance I am going to add a App.Debug.config and a App.Release.config file BUT you can follow any naming convention you want provided you wire up the rest of the approach to use this convention. My files look as follows.. App.Debug.config <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="Example Config" value="Debug"/> </appSettings> </configuration>   App.Release.config <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="Example Config" value="Release"/> </appSettings> </configuration>   Your solution will now look as follows… Step 2 – Create a bat file that will overwrite files The next step is to create a bat file that will overwrite one file with another. If you right click on the solution in the solution explorer there will be a menu option to add new items to the solution. Create a text file called “copyifnewer.bat” which will be our copy script. It’s contents should look as follows… @echo off echo Comparing two files: %1 with %2 if not exist %1 goto File1NotFound if not exist %2 goto File2NotFound fc %1 %2 /A if %ERRORLEVEL%==0 GOTO NoCopy echo Files are not the same. Copying %1 over %2 copy %1 %2 /y & goto END :NoCopy echo Files are the same. Did nothing goto END :File1NotFound echo %1 not found. goto END :File2NotFound copy %1 %2 /y goto END :END echo Done. Your solution should now look as follows…   Step 3 – Customize the Post Build event command line We now need to wire up everything – which we will do using the post build event command line in VS2010. Right click on your project and go to it’s properties We are now going to wire up the script so that when we build our project it will overwrite the default App.config with whatever file we want. The syntax goes as follows… call "$(SolutionDir)copyifnewer.bat" "$(ProjectDir)App.$(ConfigurationName).config" "$(ProjectDir)$(OutDir)\$(TargetFileName).config" Testing it If I now change my project configuration to Release   And then run my application I get the following output… Toggling between Release and Debug mode will show that the config file is changing each time. And that is it!

• Concurrent Affairs

  - by Tony Davis

  I once wrote an editorial, multi-core mania, on the conundrum of ever-increasing numbers of processor cores, but without the concurrent programming techniques to get anywhere near exploiting their performance potential. I came to the.controversial.conclusion that, while the problem loomed for all procedural languages, it was not a big issue for the vast majority of programmers. Two years later, I still think most programmers don't concern themselves overly with this issue, but I do think that's a bigger problem than I originally implied. Firstly, is the performance boost from writing code that can fully exploit all available cores worth the cost of the additional programming complexity? Right now, with quad-core processors that, at best, can make our programs four times faster, the answer is still no for many applications. But what happens in a few years, as the number of cores grows to 100 or even 1000? At this point, it becomes very hard to ignore the potential gains from exploiting concurrency. Possibly, I was optimistic to assume that, by the time we have 100-core processors, and most applications really needed to exploit them, some technology would be around to allow us to do so with relative ease. The ideal solution would be one that allows programmers to forget about the problem, in much the same way that garbage collection removed the need to worry too much about memory allocation. From all I can find on the topic, though, there is only a remote likelihood that we'll ever have a compiler that takes a program written in a single-threaded style and "auto-magically" converts it into an efficient, correct, multi-threaded program. At the same time, it seems clear that what is currently the most common solution, multi-threaded programming with shared memory, is unsustainable. As soon as a piece of state can be changed by a different thread of execution, the potential number of execution paths through your program grows exponentially with the number of threads. If you have two threads, each executing n instructions, then there are 2^n possible "interleavings" of those instructions. Of course, many of those interleavings will have identical behavior, but several won't. Not only does this make understanding how a program works an order of magnitude harder, but it will also result in irreproducible, non-deterministic, bugs. And of course, the problem will be many times worse when you have a hundred or a thousand threads. So what is the answer? All of the possible alternatives require a change in the way we write programs and, currently, seem to be plagued by performance issues. Software transactional memory (STM) applies the ideas of database transactions, and optimistic concurrency control, to memory. However, working out how to break down your program into sufficiently small transactions, so as to avoid contention issues, isn't easy. Another approach is concurrency with actors, where instead of having threads share memory, each thread runs in complete isolation, and communicates with others by passing messages. It simplifies concurrent programs but still has performance issues, if the threads need to operate on the same large piece of data. There are doubtless other possible solutions that I haven't mentioned, and I would love to know to what extent you, as a developer, are considering the problem of multi-core concurrency, what solution you currently favor, and why. Cheers, Tony.

• Trying to convert simple midlet application to Android application but running into problems.

  - by chobo2

  Hi I am trying to do some threading in Android so I took an old threading assignment I had done fora midlet and took out the midlet code and replaced it with android code(such as textview). package com.assignment1; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class Threading extends Activity { private TextView tortose; private TextView hare; private Thread hareThread; private Thread torotoseThread; private int num = 0; private int num2 = 0; public Threading() { } /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); tortose = (TextView) findViewById(R.id.TextView01); hare = (TextView) findViewById(R.id.TextView02); Hare newHare = new Hare(); hareThread = new Thread(newHare); hareThread.start(); Torotose newTortose = new Torotose(); torotoseThread = new Thread(newTortose); torotoseThread.start(); //updateDisplay(); } private synchronized void check(int value1, int value2) { if((value1-value2) >= 10) { try { wait(); } catch(Exception ex) { System.out.println(ex); } } } private synchronized void getGoing(int value1, int value2) { if((value1-value2) == 0) { try { notify(); } catch(Exception ex) { System.out.println(ex); } } } private class Hare extends Thread { public void run() { while(true) { num++; hare.setText(Integer.toString(num)); check(num, num2); try { // are threads different in andriod apps? Thread.sleep(100); // hareThread.sleep(100); } catch(Exception ex) { System.out.println(ex); } } } } private class Torotose extends Thread { public void run() { while(true) { num2++; tortose.setText(Integer.toString(num2)); getGoing(num,num2); try { Thread.sleep(200); //torotoseThread.sleep(200); } catch(Exception ex) { System.out.println(ex); } } } } } First it wanted me to change my threads to like static threads.So is this just how Android does it? Next when I run this code it just crashes with some unexpected error. I am not sure what the error is but when I try to debug it and goes to like to create a new "hare" object it shows me this. // Compiled from ClassLoader.java (version 1.5 : 49.0, super bit) public abstract class java.lang.ClassLoader { // Method descriptor #8 ()V // Stack: 3, Locals: 1 protected ClassLoader();

• Why is this simple jQuery hover event misbehaving in Internet Explorer 8?

  - by Siracuse

  I asked for help earlier on Stackoverflow involving highlighting spans with the same Class when a mouse hovers over any Span with that same Class. It is working great: http://stackoverflow.com/questions/2709686/how-can-i-add-a-border-to-all-the-elements-that-share-a-class-when-the-mouse-has $('span[class]').hover( function() { $('.' + $(this).attr('class')).css('background-color','green'); }, function() { $('.' + $(this).attr('class')).css('background-color','yellow'); } ) Here is an example of it in usage: http://dl.dropbox.com/u/638285/0utput.html However, it doesn't appear to work properly in IE8, while it DOES work in Chrome/Firefox. Here is a screenshot of it in IE8, with my mouse hovered over the " min) { min" section in the middle. As you can see, it highlighted the span that the mouse is hovering over perfectly fine. However, it has also highlighted some random spans above and below it that don't have the same class! Only the span's with the same Class as the one where the mouse is over should be highlighted green. In this screenshot, only that middle green section should be green. Here is a screenshot of it working properly in Firefox/Chrome with my mouse in the exact same position: This screenshot is correct as the span that the mouse is over (the green section) is the only one in this section that shares that class. Why is IE8 randomly green-highlighting spans when it shouldn't be (they don't share the same class) using my little jQuery snippet? Again, if you want to see it live I have it here: http://dl.dropbox.com/u/638285/0utput.html

• First TDD, Simple 2-tier C# Project - what do I unit test?

  - by Joel

  This is probably a stupid question but my googling isn't finding a satisfactory answer. I'm starting a small project in C#, with just a business layer and a data access layer - strangely, the UI will come later, and I have very little (read:no) concept / control over what it will look like. I would like to try TDD for this project. I'm using Visual Studio 2008 (soon to be 2010), I have ReSharper 5, and nUnit. Again, I want to do Test-Driven Development, but not necessarily the entire XP system. My question is - when and where do I write the first unit test? Do I only test logic before I write it, or do I test everything? It seems counter-productive to test things that have no reason to fail (auto-properties, empty constructors)...but it seems like the "No new code without a failing test" maxim requires this. Links or references are fine (but preferably to online resources, not books - I would like to get started ASAP). Thanks in advance for any guidance!

• Structuring projects & dependencies of large winforms applications in C#

  - by Benjol

  UPDATE: This is one of my most-visited questions, and yet I still haven't really found a satisfactory solution for my project. One idea I read in an answer to another question is to create a tool which can build solutions 'on the fly' for projects that you pick from a list. I have yet to try that though. How do you structure a very large application? Multiple smallish projects/assemblies in one big solution? A few big projects? One solution per project? And how do you manage dependencies in the case where you don't have one solution. Note: I'm looking for advice based on experience, not answers you found on Google (I can do that myself). I'm currently working on an application which has upward of 80 dlls, each in its own solution. Managing the dependencies is almost a full time job. There is a custom in-house 'source control' with added functionality for copying dependency dlls all over the place. Seems like a sub-optimum solution to me, but is there a better way? Working on a solution with 80 projects would be pretty rough in practice, I fear. (Context: winforms, not web) EDIT: (If you think this is a different question, leave me a comment) It seems to me that there are interdependencies between: Project/Solution structure for an application Folder/File structure Branch structure for source control (if you use branching) But I have great difficulty separating these out to consider them individually, if that is even possible. I have asked another related question here.

• What do you do when your team leader doesn't know something simple?

  - by leppie

  What do you do when your team leader does not know why the following is wrong: a.SomeProp = a.SomeProp; // no funny side-effects, plain old property He claims 15 years of programming experience, and 7 years of C#/.NET. To me, someone of 3-6 months experience should know this. What I have done: Tried to make him understand why it is wrong. He told me not to criticize him. Told him it's not about criticism, but project risk. He got upset with me. I have addressed the risk of this person with our manager (few weeks back). I have addressed my concerns with this person with our manager several times, since 1 month after I started there (7 months now). Currently, I just feel like just not going back to work... I hardly have any nails left, and this is really just the tip of the iceberg. As nothing has changed after I have spoken to the manager for the last 6 months, I feel like I need to make some sort of ultimatum. Do you have any suggestions? PS: Please do not make this subjective. I have no need for arguing. The level of incompetence is pretty clear. I just need some advice before going insane. Update: Thanks for all the answers (trying to update before close, buggers). I think I will forward this thread to our manager :) Update 2: I sent my manager another mail with my concerns, and a link to this question. Awaiting response.

• Is there a simple way for opening one (or many) opengl window in mac OS X with C++ ?

  - by Petruza

  Yes, I hate Objective-c, plus my project will be portable, so I'd like to code as much of it in C++ as possible, ideally 100%. So I have a regular C++ project made with Xcode, and want to open some OpenGL windows. edit: Damn, Glut takes over the app's control with glutMainLoop(), pretty much as SDL does, I'm trying to break free from that schemes. Will try freeglut, although I can't find OSX binaries, and I always have such bad luck trying to compile someone else's code.

• I've only programmed in AS3; What's the easiest practice in Flash CS4 to create simple animations?

  - by Zando

  So I've been using Flash for awhile, but rarely ever use the authoring tool. I want to create a quick little slideshow in which a user clicks buttons, and assets on the screen fade in an out as you move from slide to slide. I don't want to do this programatically...what's the quickest route to go about doing this, with using some AS3 but primarily relying on CS4's authoring tools? I remember when I first learned flash, years ago, you placed elements on stage and stretched them out over multiple frames. That seems like a lot of work...I'd rather just have, say, 10 total frames, each frame being a step in the slideshow, and each click of the next button going to that next frame, with each frame having its own animations.

• Updating the value of a math equation with YUI slider and simple radio buttons.

• Simple way to decrease values without making a new attribute?

  - by Jam

  I'm making a program where you're firing a 'blaster', and I have 5 ammo. I'm blasting an alien who has 5 health. At the end I instantiate the player and make him blast 6 times to check that the program works correctly. But the way I've done it makes it so that the amount won't decrease. Is there an easy fix to this, or do I just have to make a new attribute for ammo and health? Here's what I have: class Player(object): """ A player in a shooter game. """ def blast(self, enemy, ammo=5): if ammo>=1: ammo-=1 print "You have blasted the alien." print "You have", ammo, "ammunition left." enemy.die(5) else: print "You are out of ammunition!" class Alien(object): """ An alien in a shooter game. """ def die(self, health=5): if health>=1: health-=1 print "The alien is wounded. He now has", health, "health left." elif health==0: health-=1 print "The alien gasps and says, 'Oh, this is it. This is the big one. \n" \ "Yes, it's getting dark now. Tell my 1.6 million larvae that I loved them... \n" \ "Good-bye, cruel universe.'" else: print "The alien's corpse sits up momentarily and says, 'No need to blast me, I'm dead already!" # main print "\t\tDeath of an Alien\n" hero = Player() invader = Alien() hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) raw_input("\n\nPress the enter key to exit.")

• Why is my simple recusive method for this game always off by 1?

  - by FrankTheTank

  I'm attempting to create a text-based version of this game: http://www.cse.nd.edu/java/SameGame.html Here is the code I have so far: #include <iostream> #include <vector> #include <ctime> class Clickomania { public: Clickomania(); std::vector<std::vector<int> > board; int move(int, int); bool isSolved(); void print(); void pushDown(); bool isValid(); }; Clickomania::Clickomania() : board(12, std::vector<int>(8,0)) { srand((unsigned)time(0)); for(int i = 0; i < 12; i++) { for(int j = 0; j < 8; j++) { int color = (rand() % 3) + 1; board[i][j] = color; } } } void Clickomania::pushDown() { for(int i = 0; i < 8; i++) { for(int j = 0; j < 12; j++) { if (board[j][i] == 0) { for(int k = j; k > 0; k--) { board[k][i] = board[k-1][i]; } board[0][i] = 0; } } } } int Clickomania::move(int row, int col) { bool match = false; int totalMatches = 0; if (row > 12 || row < 0 || col > 8 || col < 0) { return 0; } int currentColor = board[row][col]; board[row][col] = 0; if ((row + 1) < 12) { if (board[row+1][col] == currentColor) { match = true; totalMatches++; totalMatches += move(row+1, col); } } if ((row - 1) >= 0) { if (board[row-1][col] == currentColor) { match = true; totalMatches++; totalMatches += move(row-1, col); } } if ((col + 1) < 8) { if (board[row][col+1] == currentColor) { match = true; totalMatches++; totalMatches += move(row, col+1); } } if ((col - 1) >= 0) { if (board[row][col-1] == currentColor) { match = true; totalMatches++; totalMatches += move(row, col-1); } } return totalMatches; } void Clickomania::print() { for(int i = 0; i < 12; i++) { for(int j = 0; j < 8; j++) { std::cout << board[i][j]; } std::cout << "\n"; } } int main() { Clickomania game; game.print(); int row; int col; std::cout << "Enter row: "; std::cin >> row; std::cout << "Enter col: "; std::cin >> col; int numDestroyed = game.move(row,col); game.print(); std::cout << "Destroyed: " << numDestroyed << "\n"; } The method that is giving me trouble is my "move" method. This method, given a pair of coordinates, should delete all the squares at that coordinate with the same number and likewise with all the squares with the same number connected to it. If you play the link I gave above you'll see how the deletion works on a click. int Clickomania::move(int row, int col) { bool match = false; int totalMatches = 0; if (row > 12 || row < 0 || col > 8 || col < 0) { return 0; } int currentColor = board[row][col]; board[row][col] = 0; if ((row + 1) < 12) { if (board[row+1][col] == currentColor) { match = true; totalMatches++; totalMatches += move(row+1, col); } } if ((row - 1) >= 0) { if (board[row-1][col] == currentColor) { match = true; totalMatches++; totalMatches += move(row-1, col); } } if ((col + 1) < 8) { if (board[row][col+1] == currentColor) { match = true; totalMatches++; totalMatches += move(row, col+1); } } if ((col - 1) >= 0) { if (board[row][col-1] == currentColor) { match = true; totalMatches++; totalMatches += move(row, col-1); } } return totalMatches; } My move() method above works fine, as in, it will delete the appropriate "blocks" and replace them with zeros. However, the number of destroyed (value returned) is always one off (too small). I believe this is because the first call of move() isn't being counted but I don't know how to differentiate between the first call or subsequent calls in that recursive method. How can I modify my move() method so it returns the correct number of destroyed blocks?

• Know any unobstrusive, simple GUI guidelines or design recommendations for notifications?

  - by Vinko Vrsalovic

  Hello again. I'm in the process of designing and testing various ideas for an application whose main functionality will be to notify users of occurring events and offer them with a choice of actions for each. The standard choice would be to create a queue of events showing a popup in the taskbar with the events and actions, but I want this tool to be the less intrusive and disrupting as possible. What I'm after is a good book or papers on studies of how to maximize user productivity in these intrinsically disruptive scenarios (in other words, how to achieve the perfect degree of annoying-ness, not too much, not too little). The user is supposedly interested in these events, they subscribe to them and can choose the actions to perform on each. I prefer books and papers, but the usual StackOverflow wisdom is appreciated as well. I'm after things like: Don't use popups, use instead X Show popups at most 3 seconds Show them in the left corner Use color X because it improves readability and disrupts less That is, cognitive aspects of GUI design that would help users in such a scenario.

• Is there anything like Unity for simple things that don't require an interface?

  - by Dave

  Perhaps I'm misapplying Unity, but here goes. I have a couple of applications, both of which load the same plugin assemblies. All assemblies require a library, and I want them to be able to access this library via Unity. However, in order to use Unity, or any other IoC framework, I'd have to write an interface for this library. I will probably do this, but since an interface isn't really needed for anything other than to support Unity, I am afraid that this means that I am 1) missing the point, or 2) misapplying the framework. If I avoid something that offers me DI, then I'd have to make the library class a singleton, and then pass it to all of the plugin constructors, or via a public property, and I don't want to do this. That said, and without actually implementing anything with Unity yet, I'm not getting one other detail -- although Unity will let me request the library via Resolve<, my plugins will still need to have a reference to the Unity instance that is created in the main applications. So is this a case where your only option is to pass the Unity reference to all of the plugins, but then it's convenient from that point on, merely because you can use Unity to get at all of the other dependencies?

• Using .NET C#, I need to create a simple program that responds whenever it picks up any sound from t

  - by David

  I am trying to create a program that will sit and wait until it picks up on any sound (i.e. a doorbell), and in response, triggers an event function that I can use to run some code. My exact goal is to have it run wmplayer playing a sound of a dog barking whenever it picks up something as loud as a doorbell from the microphone input. Thanks! --David

• How Do I make a simple .htaccess internal redirect Catch All script while forwarding POST data?

  - by RB

  I just want to catch all requests and forward them internally to my catchall page with all POST data intact Catch all page: http://www.mydomain.com/addons/redirect/catch-all.php I've tried so many combinations, but my server doesn't want to redirect internally if I specify more than catch-all.php # Internally redirect all pages to "Catch" page Options +FollowSymLinks RewriteEngine on RewriteRule (.*) /addons/redirect/catch-all.php [L] Also, do I need [L] or is it useless for internal redirects? Then, what php code would I use to grab the POST data, use it, and finally PHP redirect the page to the originally requested page Would it be done just as normal by using $_POST['variable_name']; or something different? Then, how would I go about calling the originally requested page, so I can tell PHP to header location direct them to that page? Thanks! UPDATE: Ha sick, nevermind. The condition DOES work. Here's my code: # Internally redirect all pages to "Catch" page Options +FollowSymLinks RewriteEngine on RewriteCond %{REQUEST_URI} !^/robots.txt$ RewriteCond %{REQUEST_URI} !\.(gif¦jpe?g¦png¦css¦js¦pdf¦doc¦xml)$ RewriteCond %{REQUEST_URI} !^/addons/redirect/catch-all\.php$ RewriteRule (.*)$ /addons/redirect/catch-all.php?q=$1 [L] Thanks guys for the inspiration! Now time to get that PHP to work...
