  • Planning for Recovery

    Uncertainty sets the tone of business planning these days and past precedents, 'rules of thumb' and trading history provide little comfort when assessing future prospects. After 18 years of constant growth in GDP, planning is no longer about extrapolating past performance and adjusting for growth. It is now about constantly testing the temperature of the water, formulating scenarios, assessing risk and assigning probabilities. So how does one plan for recovery and improve forecast accuracy in such a volatile environment?

  • 2d, Top-down map with different levels

    - by Ktash
    So, I'm creating a 2d, top down, sprite based (tiled) game, and right now I'm working on maps (well, a map editor at the moment, but it will be creating my maps, so basically the same thing). The scenario So, I'm thinking about efficiency and creating a map in pieces. In each piece, I plan on having 'layers'. Basically, I plan on rendering it down to a 'below hero' level, and an 'above hero' level, with the hero rendered in between obviously. There will likely also be a 'on level with hero' layer, but I'm not quite there yet. Not even worrying about events or interaction yet. Just looking to get a hero on the screen. Now for movement, I obviously need to know what tiles can be moved and in what direction. My plan at the moment is each tile getting 8 bits (4 'can enter in direction' bits, 4 'can leave in direction'). This will allow me to limit movement and even allow one way directional movement. The dilemma This works great for a lot of scenarios. It will allow me to store a map in essentially 3 layers, a string, and gives me flexibility going forward. However, I can't create maps that themselves have layers. A good example is a bridge where the user can go under or over the bridge without invalid moves being allowed. I can't create a platform and allow movement underneath. These are things I would like to be able to include in my game. My idea In theory, I could allow multiple hero layers and then allow multiple sets of 'below' and 'above' layers (or sandwich layers). But this complicates my system, and makes movement between maps potentially tricky (If the hero is on the third layer at the edge of a map, but that corresponds to the second layer on the other map, how can I allow or disallow movement). My question Is there a better way to manage multiple maps with multiple levels like this where a users level may be 'connected' on different levels on different maps? Or even... Am I doing this the hard way? Is there a more standard way to handle top-down 2d tiled maps that I am just not aware of? Things to note or that might be helpful This will be done in Javascript (transferred around in JSON) State will need to be transferred quickly, so a map-id and x/y/direction should be enough to get me a boolean 'can move' value Maps will not be standard sized (though they will be in a certain number of tiles) Making an editor tool so that I can have others help, so something that I can create in a tool would be helpful 'Teleportation' locations will likely need to exist to get into building maps and to and from different map sets (which will not necessarily be connected), but have not been created yet (lumping in with events at the moment).

  • C++ Without Source Files

    - by Snowman
    Bjarne Stroustrup mentions in his book "The C++ Programming Language, 4th Edition" that not all C++ implementations use files to store and compile code: There are systems that do not store, compile, and present C++ programs to the programmer as sets of files. (Chapter 15, page 419) Later in the chapter, he reiterates that certain implementations do not use files but he does not give any examples. How would such an environment function compared to a more common file-based environment?

  • Why use other bases when programming [closed]

    - by JMD
    Possible Duplicate: Why use other number bases when programming My coworkers and I have been bending our minds to figuring out why anyone would go out of their way to program numbers in a base other than base 10. I suggested that perhaps you could optimize longer equations by putting the variables in the correct base you are working with (for instance, if you have only sets of 5 of something with no remainders you could use base 5), but I'm not sure if that's true. Any thoughts?

  • Tuple in C# 4.0

    - by Jalpesh P. Vadgama
    C# 4.0 language includes a new feature called Tuple. Tuple provides us a way of grouping elements of different data type. That enables us to use it a lots places at practical world like we can store a coordinates of graphs etc. In C# 4.0 we can create Tuple with Create method. This Create method offer 8 overload like following. So you can group maximum 8 data types with a Tuple. Followings are overloads of a data type. Create(T1)- Which represents a tuple of size 1 Create(T1,T2)- Which represents a tuple of size 2 Create(T1,T2,T3) – Which represents a tuple of size 3 Create(T1,T2,T3,T4) – Which represents a tuple of size 4 Create(T1,T2,T3,T4,T5) – Which represents a tuple of size 5 Create(T1,T2,T3,T4,T5,T6) – Which represents a tuple of size 6 Create(T1,T2,T3,T4,T5,T6,T7) – Which represents a tuple of size 7 Create(T1,T2,T3,T4,T5,T6,T7,T8) – Which represents a tuple of size 8 Following are some example code for tuple. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace TupleExample { class Program { static void Main(string[] args) { var tuple = System.Tuple.Create<string, string, string>("Jalpesh", "P", "Vadgama"); Console.WriteLine(tuple); var t = System.Tuple.Create<int, string>(1, "Jalpesh"); Console.WriteLine(t); } } } Following is a output of above as expected. You can also access values insides Tuple with ItemN property. Where N represents particular number of item in tuple. Following is an example of it. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace TupleExample { class Program { static void Main(string[] args) { var tuple = System.Tuple.Create<string, string, string>("Jalpesh", "P", "Vadgama"); Console.WriteLine(tuple.Item1); Console.WriteLine(tuple.Item2); Console.WriteLine(tuple.Item3); } } } Here you can see I have printed items with Item1,Item2 and Item3 . Following is the output of above code.   Even we can create a nested tuple also following is code for nested tuple. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace TupleExample { class Program { static void Main(string[] args) { var tuple = System.Tuple.Create(1,"Jalpesh",new Tuple<string,string>("P","Vadgama")); Console.WriteLine(tuple.Item1); Console.WriteLine(tuple.Item2); Console.WriteLine(tuple.Item3); } } } Following is a output above code as expected. As you can see there are unlimited possibilities we can do lots of things with Tuple. Hope you liked it. Stay tuned for more. Till then Happy Programming!!

  • Flow-Design Cheat Sheet &ndash; Part II, Translation

    - by Ralf Westphal
    In my previous post I summarized the notation for Flow-Design (FD) diagrams. Now is the time to show you how to translate those diagrams into code. Hopefully you feel how different this is from UML. UML leaves you alone with your sequence diagram or component diagram or activity diagram. They leave it to you how to translate your elaborate design into code. Or maybe UML thinks it´s so easy no further explanations are needed? I don´t know. I just know that, as soon as people stop designing with UML and start coding, things end up to be very different from the design. And that´s bad. That degrades graphical designs to just time waste on paper (or some designer). I even believe that´s the reason why most programmers view textual source code as the only and single source of truth. Design and code usually do not match. FD is trying to change that. It wants to make true design a first class method in every developers toolchest. For that the first prerequisite is to be able to easily translate any design into code. Mechanically, without thinking. Even a compiler could do it :-) (More of that in some other article.) Translating to Methods The first translation I want to show you is for small designs. When you start using FD you should translate your diagrams like this. Functional units become methods. That´s it. An input-pin becomes a method parameter, an output-pin becomes a return value: The above is a part. But a board can be translated likewise and calls the nested FUs in order: In any case be sure to keep the board method clear of any and all business logic. It should not contain any control structures like if, switch, or a loop. Boards do just one thing: calling nested functional units in proper sequence. What about multiple input-pins? Try to avoid them. Replace them with a join returning a tuple: What about multiple output-pins? Try to avoid them. Or return a tuple. Or use out-parameters: But as I said, this simple translation is for simple designs only. Splits and joins are easily done with method translation: All pretty straightforward, isn´t it. But what about wires, named pins, entry points, explicit dependencies? I suggest you don´t use this kind of translation when your designs need these features. Translating to methods is for small scale designs like you might do once you´re working on the implementation of a part of a larger design. Or maybe for a code kata you´re doing in your local coding dojo. Instead of doing TDD try doing FD and translate your design into methods. You´ll see that way it´s much easier to work collaboratively on designs, remember them more easily, keep them clean, and lessen the need for refactoring. Translating to Events [coming soon]

  • java.lang.ClassCastException: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl while starting the w

    - by venkat
    Hi, As part of our application we are using apache's xerces jaxp parser. When we deploy the application on weblogic9.2, we are getting the following error. org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.apache.cxf.wsdl.WSDLManager' defined in class path resource [META-INF/cxf/cxf.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.apache.cxf.wsdl11.WSDLManagerImpl]: Constructor threw exception; nested exception is java.lang.ClassCastException: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl As per our analysis, i)The weblogic is trying to to load its own DocumentBuilderFactoryImpl which is present in weblogic.jar instead of apache's xerces. We tried the following to force the weblogic to load DocumentBuilderFactoryImpl from xerces i)we have added the following tag into weblogic.xml true ii)we have put latest versions of xalan in jre/lib/endorced folder. this didnt resolve our problem. ii) we have added entries in weblogic-application.xml webapp.encoding.default UTF-8 javax.jws. org.apache.xerces. org.apache.xerces.jaxp.* ii)Added the following entry in weblogic-application.xml <parser-factory> <saxparser-factory>org.apache.xerces.jaxp.SAXParserFactoryImpl</saxparser-factory> <document-builder-factory>org.apache.xerces.jaxp.DocumentBuilderFactoryImpl </document-builder-factory> org.apache.xalan.processor.TransformerFactoryImpl iii)Added jaxp.properties to load DocumentBuilderFactoryImpl from xerces to the jre/lib and started the server.In this case, the weblogic didnt start. iv)Then we started the server first and then copied the jaxp.properties file during the run time when server starts.But no success None of the above worked for us. Any help is highly appreciated. Thanks in advance, Venkat.

  • codingBat repeatEnd using regex

    - by polygenelubricants
    I'm trying to understand regex as much as I can, so I came up with this regex-based solution to codingbat.com repeatEnd: Given a string and an int N, return a string made of N repetitions of the last N characters of the string. You may assume that N is between 0 and the length of the string, inclusive. public String repeatEnd(String str, int N) { return str.replaceAll( ".(?!.{N})(?=.*(?<=(.{N})))|." .replace("N", Integer.toString(N)), "$1" ); } Explanation on its parts: .(?!.{N}): asserts that the matched character is one of the last N characters, by making sure that there aren't N characters following it. (?=.*(?<=(.{N}))): in which case, use lookforward to first go all the way to the end of the string, then a nested lookbehind to capture the last N characters into \1. Note that this assertion will always be true. |.: if the first assertion failed (i.e. there are at least N characters ahead) then match the character anyway; \1 would be empty. In either case, a character is always matched; replace it with \1. My questions are: Is this technique of nested assertions valid? (i.e. looking behind during a lookahead?) Is there a simpler regex-based solution?

  • C# Gui setting control.Enabled to false fires OnClick event???

    - by Daniel
    For some really weird reason when i set the .Enabled property to false on a simple text box on a small GUI, it fires a radio buttons OnClick event and its causing lots of problems. I have breakpointed the txtBox.Enabled = false; and after stepping over OR into it i jump straight to the OnClick event of the radio button control Here is the call stack as that happened: TestGUI.exe!TestGUI.frmMain.radiobuttonClicked(object sender = {Text = "Download Single Episode" Checked = true}, System.EventArgs e = {System.EventArgs}) Line 67 C# System.Windows.Forms.dll!System.Windows.Forms.Control.OnClick(System.EventArgs e) + 0x70 bytes System.Windows.Forms.dll!System.Windows.Forms.RadioButton.OnClick(System.EventArgs e) + 0x27 bytes System.Windows.Forms.dll!System.Windows.Forms.RadioButton.OnEnter(System.EventArgs e = {System.EventArgs}) + 0x3e bytes System.Windows.Forms.dll!System.Windows.Forms.Control.NotifyEnter() + 0x20 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.UpdateFocusedControl() + 0x195 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.AssignActiveControlInternal(System.Windows.Forms.Control value = {Text = "Download Single Episode" Checked = true}) + 0x54 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.ActivateControlInternal(System.Windows.Forms.Control control, bool originator = false) + 0x76 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.SetActiveControlInternal(System.Windows.Forms.Control value = {Text = "Download Single Episode" Checked = true}) + 0x73 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.SetActiveControl(System.Windows.Forms.Control ctl) + 0x33 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.ActiveControl.set(System.Windows.Forms.Control value) + 0x5 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.Select(bool directed, bool forward) + 0x1b bytes System.Windows.Forms.dll!System.Windows.Forms.Control.SelectNextControl(System.Windows.Forms.Control ctl, bool forward, bool tabStopOnly, bool nested, bool wrap) + 0x7b bytes System.Windows.Forms.dll!System.Windows.Forms.Control.SelectNextControlInternal(System.Windows.Forms.Control ctl, bool forward, bool tabStopOnly, bool nested, bool wrap) + 0x4a bytes System.Windows.Forms.dll!System.Windows.Forms.Control.SelectNextIfFocused() + 0x61 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.Enabled.set(bool value) + 0x42 bytes What the hell?

  • Spring Test / JUnit problem - unable to load application context

    - by HDave
    I am using Spring for the first time and must be doing something wrong. I have a project with several Bean implementations and now I am trying to create a test class with Spring Test and JUnit. I am trying to use Spring Test to inject a customized bean into the test class. Here is my test-applicationContext.xml: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="............."> <bean id="MyUuidFactory" class="com.myapp.UuidFactory" scope="singleton" > <property name="typeIdentifier" value="CLS" /> </bean> <bean id="ThingyImplTest" class="com.myapp.ThingyImplTest" scope="singleton"> <property name="uuidFactory"> <idref local="MyUuidFactory" /> </property> </bean> </beans> The injection of MyUuidFactory instance goes along with the following code from within the test class: private UuidFactory uuidFactory; public void setUuidFactory(UuidFactory uuidFactory) { this.uuidFactory = uuidFactory; } However, when I go to run the test (in Eclipse or command line) I get the following error (stack trace omitted for brevity): Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MyImplTest' defined in class path resource [test-applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.lang.String' to required type 'com.myapp.UuidFactory' for property 'uuidFactory'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [com.myapp.UuidFactory] for property 'uuidFactory': no matching editors or conversion strategy found Funny thing is, the Eclipse/Spring XML editor shows errors of I misspell any of the types or idrefs. If I leave the bean in, but comment out the dependency injection, everything work until I get a NullPointerException while running the test...which makes sense.

  • Grails Mail port configuration

    - by bsreekanth
    Hello, I am trying to send mail through grails mail plugin. I configured according to the documentation, and also followed few blog posts (http://blog.lourish.com/2010/04/02/sending-asynchronous-html-email-in-grails-with-activemq-jms-and-gmail/). That post mention that the closure way of declaring the configuration overrides others, but not true. Anyway I tried both approach, but seems like the port is still use the smtp default one. I get the below exception. exception: org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25; nested exception is: java.net.ConnectException: Connection refused: connect Now, I wrote a small program directly using the java mail library, and I could send the mail with that. The configuration is shown below. tried additional config "mail.smtp.port":"465"", but no change.. used the parameters mentioned in the above blog post, result same grails { mail { host = "smtp.gmail.com" port = "465" username = "[email protected]" password = "mypwd" props = ["mail.smtp.auth":"true", // "mail.smtp.port":"465", "mail.smtp.socketFactory.port":"465", "mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory", "mail.smtp.socketFactory.fallback":"false"] } } thanks in advance.. Update: It is not port or firewall config, as when I made a grails application from scratch, and tried with the same config, everything works. Also, asked in grails forum http://grails.1312388.n4.nabble.com/grails-mail-mailSender-does-not-have-config-values-td2237704.html#a2237704 . Hope get a lead to try.
