• Making Hudson job depend on another job

  - by Jonik

  I have two Hudson jobs: Upload Launch-instance I want to make Launch-instance dependent on the other one, so that triggering Launch-instance automatically causes Upload to be run first. Can I achieve this using Hudson's built-in features or with a plugin? Note that I do not want Upload to always trigger Launch-instance, which is what the "Build after other projects are built" option on Launch-instance would do. What I want is more analogous to how depends attribute works for an Ant target.

• Javascript static method intheritance

  - by Matteo Pagliazzi

  I want to create a javascript class/object that allow me to have various method: Model class Model.all() » static method Model.find() » static method Model delete() » instance method Model save() » instance method Model.create() » static that returns a new Model instance For static method I can define them using: Model.staticMethod(){ method } while for instance method is better to use: function Model(){ this.instanceMethod = function(){} } and then create a new instance or using prototype? var m = function Model(){ } m.prototype.method() = function(){ } Now let's say that I want to create a new class based on Model, how to inherit not only its prototypes but also its static methods?

• Using Guice with circular dependencies

  - by Yury Litvinov

  Consider this simple example. Class A { B b; A() { this.b = new B(this); } } In this example instance A knows about instance B, and instance B knows about instance A. My question is: how to instantiate instance A with Guice, i.e. how to make Guice take care of this complex circle dependencies?

• Where should I initialize variables for an OO Recursive Descent Parse Tree?

  - by Vasto

  I'd like to preface this by stating that this is for a class, so please don't solve this for me. One of my labs for my cse class is creating an interpreter for a BNF that was provided. I understand most of the concepts, but I'm trying to build up my tree and I'm unsure where to initialize values. I've tried in both the constructor, and in the methods but Eclipse's debugger still only shows the left branch, even though it runs through completely. Here is my main procedure so you can get an idea of how I'm calling the methods. public class Parser { public static void main(String[] args) throws IOException { FileTokenizer instance = FileTokenizer.Instance(); FileTokenizer.main(args); Prog prog = new Prog(); prog.ParseProg(); prog.PrintProg(); prog.ExecProg(); } Now here is My Prog class: public class Prog { private DeclSeq ds; private StmtSeq ss; Prog() { ds = new DeclSeq(); ss = new StmtSeq(); } public void ParseProg() { FileTokenizer instance = FileTokenizer.Instance(); instance.skipToken(); //Skips program (1) // ds = new DeclSeq(); ds.ParseDS(); instance.skipToken(); //Skips begin (2) // ss = new StmtSeq(); ss.ParseSS(); instance.skipToken(); } I've tried having Prog() { ds = null; ss = null; } public void ParseProg() { FileTokenizer instance = FileTokenizer.Instance(); instance.skipToken(); //Skips program (1) ds = new DeclSeq(); ds.ParseDS(); ... But it gave me the same error. I need the parse tree built up so I can do a pretty print and an execute command, but like I said, I only get the left branch. Any help would be appreciated. Explanations why are even more so appreciated. Thank you, Vasto

• Singleton with eager initialization

  - by jesper

  I have class X that takes much time to initialize itself. I want to make that class singleton and force its creation when rails application starts. I've made the singleton: class X @@instance = nil def self.instance if @@instance.nil? @@instance = X.new puts 'CREATING' end return @@instance end private_class_method :new end The problem is that every time I use this class I see 'CREATING' in logs. I've tried to put creation of class in initializers directory but it doesn't work either.

  I have this Singleton class inside a Web Application . public class MyDAO { private static MyDAO instance; private MyDAO() { } public static MyDAO getInstance() { if (instance == null) { instance = new MyDAO(); } return instance; } I will access it this way public void get_Data() { MyDAO dao = MyDAO.getInstance(); } How many Objects of MyDAO class will be created if there are 3 Users accessing the Application ?? Will there be one instance of MyDAO per User ??

It will provide excellent bus sharing at the cost of bus data transfer rates. Although not a critical issue, it may be worth considering setting the MaxReadRequest size to 256 or 512 to increase throughput on the PCI Express bus. Some drivers (for example the Brocade Fibre Channel driver) allow one to override the firmware settings. Where possible, this BIOS configuration setting is worth increasing it a little more for better performance at a small reduction of bus sharing. ==================================================================================================== PCIe ASPM check. ---------------------------------------------------------------------------------------------------- Test 1 of 2: PCIe ASPM ACPI test.

Section 5.2.9 of the ACPI specification states that if the X_FIRMWARE_CTRL field contains a non zero value then the FIRMWARE_CTRL field *must* be zero. This error is also detected by the Linux kernel. If FIRMWARE_CTRL and X_FIRMWARE_CTRL are defined, then the kernel just uses the 64 bit version of the pointer. PASSED: Test 1, Table HPET passed.

• How to leverage the internal HTTP endpoint available on Azure web roles?

  - by Alfredo Delsors

  Imagine you have a Web application using an in-memory collection that changes occasionally but is used very often. The collection gets loaded from storage on the Application_Start global.asax event and is updated whenever its content changes. If you want to deploy this application on Azure you need to keep in mind that more than one instance of the application can be running at any time and therefore you need to provide some mechanism to keep all instances informed with the latest changes. Because the communication through internal endpoints between Azure role instances is at no cost, a good solution can be maintaining the information on Azure Storage Tables, reading its contents on the Application_Start event and populating its changes to all other instances using the internal HTTP port available on Azure Web Roles. You need to follow these steps to leverage the internal HTTP endpoint available on Azure web roles to maintain all instances up to date. 1.   Define an internal HTTP endpoint in the Web Role properties, for example InternalHttpEndpoint   2.   Add a new WCF service to the Web Role, for example NotificationService.svc 3.   Disable multiple site bindings in web.config: <serviceHostingEnvironment multipleSiteBindingsEnabled="false"> 4.   Add a method on the new service to receive notifications from other role instances. namespace Service { [ServiceContract] public interface INotificationService { [OperationContract(IsOneWay = true)] void Notify(Information info); } } 5.   Declare a class that inherits from System.ServiceModel.Activation.ServiceHostFactory and override the method CreateServiceHost to host the internal endpoint. public class InternalServiceFactory : ServiceHostFactory { protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { var internalEndpointAddress = string.Format( "http://{0}/NotificationService.svc", RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["InternalHttpEndpoint"].IPEndpoint); ServiceHost host = new ServiceHost( typeof(NotificationService), new Uri(internalEndpointAddress)); BasicHttpBinding binding = new BasicHttpBinding(SecurityMode.None); host.AddServiceEndpoint( typeof(INotificationService), binding, internalEndpointAddress); return host; } } Note that you can use SecurityMode.None because the internal endpoint is private to the instances of the service. 6.   Edit the markup of the service right clicking the svc file and selecting "View markup" to add the new factory as the factory to be used to create the service <%@ ServiceHost Language="C#" Debug="true" Factory="Service.InternalServiceFactory" Service="Service.NotificationService" CodeBehind="NotificationService.svc.cs" %> 7.   Now you can notify changes to other instances using this code: var current = RoleEnvironment.CurrentRoleInstance; var endPoints = current.Role.Instances .Where(instance => instance != current) .Select(instance => instance.InstanceEndpoints["InternalHttpEndpoint"]); foreach (var ep in endPoints) { EndpointAddress address = new EndpointAddress( String.Format("http://{0}/NotificationService.svc", ep.IPEndpoint)); BasicHttpBinding binding = new BasicHttpBinding(SecurityMode.None); var factory = new ChannelFactory<INotificationService>(binding); INotificationService instance = factory.CreateChannel(address); instance.Notify(changedinfo); }

• AWS EC2 Oracle RDB - Storing and managing my data

  - by llaszews

  When create an Oracle Database on the Amazon cloud you will need to store you database files somewhere on the EC2 cloud. There are basically three places where database files can be stored: 1. Local drive - This is the local drive that is part of the virtual server EC2 instance. 2. Elastic Block Storage (EBS) - Network attached storage that appears as a local drive. 3. Simple Storage Server (S3) - 'Storage for the Internet'. S3 is not high speed and intended for store static document type files. S3 can also be used for storing static web page files. Local drives are ephemeral so not appropriate to be used as a database storage device. The leaves EBS which is the best place to store database files. EBS volumes appear as local disk drives. They are actually network-attached to an Amazon EC2 instance. In addition, EBS persists independently from the running life of a single Amazon EC2 instance. If you use an EBS backed instance for your database data, it will remain available after reboot but not after terminate. In many cases you would not need to terminate your instance but only stop it, which is equivalent of shutdown. In order to save your database data before you terminate an instance, you can snapshot the EBS to S3. Using EBS as a data store you can move your Oracle data files from one instance to another. This allows you to move your database from one region or or zone to another. Unfortunately, to scale out your Oracle RDS on AWS you can not have read only replicas. This is only possible with the other Oracle relational database - MySQL. The free micro instances use EBS as its storage. This is a very good white paper that has more details: AWS Storage Options This white paper also discusses: SQS, SimpleDB, and Amazon RDS in the context of storage devices. However, these are not storage devices you would use to store an Oracle database. This slide deck discusses a lot of information that is in the white paper: AWS Storage Options slideshow

• Configuring Multiple Instances of MySQL in Solaris 11

  - by rajeshr

  Recently someone asked me for steps to configure multiple instances of MySQL database in an Operating Platform. Coz of my familiarity with Solaris OE, I prepared some notes on configuring multiple instances of MySQL database on Solaris 11. Maybe it's useful for some: If you want to run Solaris Operating System (or any other OS of your choice) as a virtualized instance in desktop, consider using Virtual Box. To download Solaris Operating System, click here. Once you have your Solaris Operating System (Version 11) up and running and have Internet connectivity to gain access to the Image Packaging System (IPS), please follow the steps as mentioned below to install MySQL and configure multiple instances: 1. Install MySQL Database in Solaris 11 $ sudo pkg install mysql-51 2. Verify if the mysql is installed: $ svcs -a | grep mysql Note: Service FMRI will look similar to the one here: svc:/application/database/mysql:version_51 3. Prepare data file system for MySQL Instance 1 zfs create rpool/mysql zfs create rpool/mysql/data zfs set mountpoint=/mysql/data rpool/mysql/data 4. Prepare data file system for MySQL Instance 2 zfs create rpool/mysql/data2 zfs set mountpoint=/mysql/data rpool/mysql/data2 5. Change the mysql/datadir of the MySQL Service (SMF) to point to /mysql/data $ svcprop mysql:version_51 | grep mysql/data $ svccfg -s mysql:version_51 setprop mysql/data=/mysql/data 6. Create a new instance of MySQL 5.1 (a) Copy the manifest of the default instance to temporary directory: $ sudo cp /lib/svc/manifest/application/database/mysql_51.xml /var/tmp/mysql_51_2.xml (b) Make appropriate modifications on the XML file $ sudo vi /var/tmp/mysql_51_2.xml - Change the "instance name" section to a new value "version_51_2" - Change the value of property name "data" to point to the ZFS file system "/mysql/data2" 7. Import the manifest to the SMF repository: $ sudo svccfg import /var/tmp/mysql_51_2.xml 8. Before starting the service, copy the file /etc/mysql/my.cnf to the data directories /mysql/data & /mysql/data2. $ sudo cp /etc/mysql/my.cnf /mysql/data/ $ sudo cp /etc/mysql/my.cnf /mysql/data2/ 9. Make modifications to the my.cnf in each of the data directories as required: $ sudo vi /mysql/data/my.cnf Under the [client] section port=3306 socket=/tmp/mysql.sock ---- ---- Under the [mysqld] section port=3306 socket=/tmp/mysql.sock datadir=/mysql/data ----- ----- server-id=1 $ sudo vi /mysql/data2/my.cnf Under the [client] section port=3307 socket=/tmp/mysql2.sock ----- ----- Under the [mysqld] section port=3307 socket=/tmp/mysql2.sock datadir=/mysql/data2 ----- ----- server-id=2 10. Make appropriate modification to the startup script of MySQL (managed by SMF) to point to the appropriate my.cnf for each instance: $ sudo vi /lib/svc/method/mysql_51 Note: Search for all occurences of mysqld_safe command and modify it to include the --defaults-file option. An example entry would look as follows: ${MySQLBIN}/mysqld_safe --defaults-file=${MYSQLDATA}/my.cnf --user=mysql --datadir=${MYSQLDATA} --pid=file=${PIDFILE} 11. Start the service: $ sudo svcadm enable mysql:version_51_2 $ sudo svcadm enable mysql:version_51 12. Verify that the two services are running by using: $ svcs mysql 13. Verify the processes: $ ps -ef | grep mysqld 14. Connect to each mysqld instance and verify: $ mysql --defaults-file=/mysql/data/my.cnf -u root -p $ mysql --defaults-file=/mysql/data2/my.cnf -u root -p Some references for Solaris 11 newbies Taking your first steps with Solaris 11 Introducing the basics of Image Packaging System Service Management Facility How To Guide For a detailed list of official educational modules available on Solaris 11, please visit here For MySQL courses from Oracle University access this page.

• How to create a PeopleCode Application Package/Application Class using PeopleTools Tables

  - by Andreea Vaduva

  This article describes how - in PeopleCode (Release PeopleTools 8.50) - to enable a grid without enabling each static column, using a dynamic Application Class. The goal is to disable the following grid with three columns “Effort Date”, ”Effort Amount” and “Charge Back” , when the Check Box “Finished with task” is selected , without referencing each static column; this PeopleCode could be used dynamically with any grid. If the check box “Finished with task” is cleared, the content of the grid columns is editable (and the buttons “+” and “-“ are available): So, you create an Application Package “CLASS_EXTENSIONS” that contains an Application Class “EWK_ROWSET”. This Application Class is defined with Class extends “ Rowset” and you add two news properties “Enabled” and “Visible”: After creating this Application Class, you use it in two PeopleCode Events : Rowinit and FieldChange : This code is very ‘simple’, you write only one command : ” &ERS2.Enabled = False” → and the entire grid is “Enabled”… and you can use this code with any Grid!

• Using Delegates in C# (Part 1)

  - by rajbk

  This post provides a very basic introduction of delegates in C#. Part 2 of this post can be read here. A delegate is a class that is derived from System.Delegate.  It contains a list of one or more methods called an invocation list. When a delegate instance is “invoked” with the arguments as defined in the signature of the delegate, each of the methods in the invocation list gets invoked with the arguments. The code below shows example with static and instance methods respectively: Static Methods 1: using System; 2: using System.Linq; 3: using System.Collections.Generic; 4: 5: public delegate void SayName(string name); 6: 7: public class Program 8: { 9: [STAThread] 10: static void Main(string[] args) 11: { 12: SayName englishDelegate = new SayName(SayNameInEnglish); 13: SayName frenchDelegate = new SayName(SayNameInFrench); 14: SayName combinedDelegate =(SayName)Delegate.Combine(englishDelegate, frenchDelegate); 15: 16: combinedDelegate.Invoke("Tom"); 17: Console.ReadLine(); 18: } 19: 20: static void SayNameInFrench(string name) { 21: Console.WriteLine("J'ai m'appelle " + name); 22: } 23: 24: static void SayNameInEnglish(string name) { 25: Console.WriteLine("My name is " + name); 26: } 27: } We have declared a delegate of type SayName with return type of void and taking an input parameter of name of type string. On line 12, we create a new instance of this delegate which refers to a static method - SayNameInEnglish.  SayNameInEnglish has the same return type and parameter list as the delegate declaration.  Once a delegate is instantiated, the instance will always refer to the same target. Delegates are immutable. On line 13, we create a new instance of the delegate but point to a different static method. As you may recall, a delegate instance encapsulates an invocation list. You create an invocation list by combining delegates using the Delegate.Combine method (there is an easier syntax as you will see later). When two non null delegate instances are combined, their invocation lists get combined to form a new invocation list. This is done in line 14.  On line 16, we invoke the delegate with the Invoke method and pass in the required string parameter. Since the delegate has an invocation list with two entries, each of the method in the invocation list is invoked. If an unhandled exception occurs during the invocation of one of these methods, the exception gets bubbled up to the line where the invocation was made (line 16). If a delegate is null and you try to invoke it, you will get a System.NullReferenceException. We see the following output when the method is run: My name is TomJ'ai m'apelle Tom Instance Methods The code below outputs the same results as before. The only difference here is we are creating delegates that point to a target object (an instance of Translator) and instance methods which have the same signature as the delegate type. The target object can never be null. We also use the short cut syntax += to combine the delegates instead of Delegate.Combine. 1: public delegate void SayName(string name); 2: 3: public class Program 4: { 5: [STAThread] 6: static void Main(string[] args) 7: { 8: Translator translator = new Translator(); 9: SayName combinedDelegate = new SayName(translator.SayNameInEnglish); 10: combinedDelegate += new SayName(translator.SayNameInFrench); 11:  12: combinedDelegate.Invoke("Tom"); 13: Console.ReadLine(); 14: } 15: } 16: 17: public class Translator { 18: public void SayNameInFrench(string name) { 19: Console.WriteLine("J'ai m'appelle " + name); 20: } 21: 22: public void SayNameInEnglish(string name) { 23: Console.WriteLine("My name is " + name); 24: } 25: } A delegate can be removed from a combination of delegates by using the –= operator. Removing a delegate from an empty list or removing a delegate that does not exist in a non empty list will not result in an exception. Delegates are invoked synchronously using the Invoke method. We can also invoke them asynchronously using the BeginInvoke and EndInvoke methods which are compiler generated.

• Efficient Way to Draw Grids in XNA

  - by sm81095

  So I am working on a game right now, using Monogame as my framework, and it has come time to render my world. My world is made up of a grid (think Terraria but top-down instead of from the side), and it has multiple layers of grids in a single world. Knowing how inefficient it is to call SpriteBatch.Draw() a lot of times, I tried to implement a system where the tile would only be drawn if it wasn't hidden by the layers above it. The problem is, I'm getting worse performance by checking if it's hidden than when I just let everything draw even if it's not visible. So my question is: how to I efficiently check if a tile is hidden to cut down on the draw() calls? Here is my draw code for a single layer, drawing floors, and then the tiles (which act like walls): public void Draw(GameTime gameTime) { int drawAmt = 0; int width = Tile.TILE_DIM; int startX = (int)_parent.XOffset; int startY = (int)_parent.YOffset; //Gets the starting tiles and the dimensions to draw tiles, so only onscreen tiles are drawn, allowing for the drawing of large worlds int tileDrawWidth = ((CIGame.Instance.Graphics.PreferredBackBufferWidth / width) + 4); int tileDrawHeight = ((CIGame.Instance.Graphics.PreferredBackBufferHeight / width) + 4); int tileStartX = (int)MathHelper.Clamp((-startX / width) - 2, 0, this.Width); int tileStartY = (int)MathHelper.Clamp((-startY / width) - 2, 0, this.Height); #region Draw Floors and Tiles CIGame.Instance.GraphicsDevice.SetRenderTarget(_worldTarget); CIGame.Instance.GraphicsDevice.Clear(Color.Black); CIGame.Instance.SpriteBatch.Begin(); //Draw floors for (int x = tileStartX; x < (int)MathHelper.Clamp(tileStartX + tileDrawWidth, 0, this.Width); x++) { for (int y = tileStartY; y < (int)MathHelper.Clamp(tileStartY + tileDrawHeight, 0, this.Height); y++) { //Check if this tile is hidden by layer above it bool visible = true; for (int i = this.LayerNumber; i <= _parent.ActiveLayer; i++) { if (this.LayerNumber != (_parent.Layers - 1) && (_parent.GetTileAt(x, y, i + 1).Opacity >= 1.0f || _parent.GetFloorAt(x, y, i + 1).Opacity >= 1.0f)) { visible = false; break; } } //Only draw if visible under the tile above it if (visible && this.GetTileAt(x, y).Opacity < 1.0f) { Texture2D tex = WorldTextureManager.GetFloorTexture((Floor)_floors[x, y]); Rectangle source = WorldTextureManager.GetSourceForIndex(((Floor)_floors[x, y]).GetTextureIndexFromSurroundings(x, y, this), tex); Rectangle draw = new Rectangle(startX + x * width, startY + y * width, width, width); CIGame.Instance.SpriteBatch.Draw(tex, draw, source, Color.White * ((Floor)_floors[x, y]).Opacity); drawAmt++; } } } //Draw tiles for (int x = tileStartX; x < (int)MathHelper.Clamp(tileStartX + tileDrawWidth, 0, this.Width); x++) { for (int y = tileStartY; y < (int)MathHelper.Clamp(tileStartY + tileDrawHeight, 0, this.Height); y++) { //Check if this tile is hidden by layers above it bool visible = true; for (int i = this.LayerNumber; i <= _parent.ActiveLayer; i++) { if (this.LayerNumber != (_parent.Layers - 1) && (_parent.GetTileAt(x, y, i + 1).Opacity >= 1.0f || _parent.GetFloorAt(x, y, i + 1).Opacity >= 1.0f)) { visible = false; break; } } if (visible) { Texture2D tex = WorldTextureManager.GetTileTexture((Tile)_tiles[x, y]); Rectangle source = WorldTextureManager.GetSourceForIndex(((Tile)_tiles[x, y]).GetTextureIndexFromSurroundings(x, y, this), tex); Rectangle draw = new Rectangle(startX + x * width, startY + y * width, width, width); CIGame.Instance.SpriteBatch.Draw(tex, draw, source, Color.White * ((Tile)_tiles[x, y]).Opacity); drawAmt++; } } } CIGame.Instance.SpriteBatch.End(); Console.WriteLine(drawAmt); CIGame.Instance.GraphicsDevice.SetRenderTarget(null); //TODO: Change to new rendertarget instead of null #endregion } So I was wondering if this is an efficient way, but I'm going about it wrongly, or if there is a different, more efficient way to check if the tiles are hidden. EDIT: For example of how much it affects performance: using a world with three layers, allowing everything to draw no matter what gives me 60FPS, but checking if its visible with all of the layers above it gives me only 20FPS, while checking only the layer immediately above it gives me a fluctuating FPS between 30 and 40FPS.

• E2251 Ambiguous overloaded call to ....

  - by Eric M

  I inherited some Delphi components/code that currently compiles with C++ Builder 2007. I'm simply now trying to compile the components with C++ Builder RAD XE. I don't know Delphi (object pascal). Here are the versions of the 'Supports' functions that appear to be in conflict. Is there a compiler switch I can use to make RAD XE backward compatible? Or is there something I can do to these function calls to correct the ambiguous nature? {$IFNDEF DELPHI5} procedure FreeAndNil(var Obj); var Temp: TObject; begin Temp := TObject(Obj); Pointer(Obj) := nil; Temp.Free; end; function Supports(const Instance: IUnknown; const Intf: TGUID; out Inst): Boolean; overload; begin Result := (Instance <> nil) and (Instance.QueryInterface(Intf, Inst) = 0); end; function Supports(Instance: TObject; const Intf: TGUID; out Inst): Boolean; overload; var Unk: IUnknown; begin Result := (Instance <> nil) and Instance.GetInterface(IUnknown, Unk) and Supports(Unk, Intf, Inst); end; {$ENDIF} {$IFNDEF DELPHI6} function Supports(const Instance: TObject; const IID: TGUID): Boolean; var Temp: IUnknown; begin Result := Supports(Instance, IID, Temp); end; {$ENDIF}

• How to configure a WCF service to only accept a single client identified by a x509 certificate

  - by Johan Levin

  I have a WCF client/service app that relies on secure communication between two machines and I want to use use x509 certificates installed in the certificate store to identify the server and client to each other. I do this by configuring the binding as <security authenticationMode="MutualCertificate"/>. There is only client machine. The server has a certificate issued to server.mydomain.com installed in the Local Computer/Personal store and the client has a certificate issued to client.mydomain.com installed in the same place. In addition to this the server has the client's public certificate in Local Computer/Trusted People and the client has the server's public certificate in Local Computer/Trusted People. Finally the client has been configured to check the server's certificate. I did this using the system.servicemodel/behaviors/endpointBehaviors/clientCredentials/serviceCertificate/defaultCertificate element in the config file. So far so good, this all works. My problem is that I want to specify in the server's config file that only clients that identify themselves with the client.mydomain.com certificate from the Trusted People certificate store are allowed to connect. The correct information is available on the server using the ServiceSecurityContext, but I am looking for a way to specify in app.config that WCF should do this check instead of my having to check the security context from code. Is that possible? Any hints would be appreciated. By the way, my server's config file looks like this so far: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <services> <service name="MyServer.Server" behaviorConfiguration="CertificateBehavior"> <endpoint contract="Contracts.IMyService" binding="customBinding" bindingConfiguration="SecureConfig"> </endpoint> <host> <baseAddresses> <add baseAddress="http://localhost/SecureWcf"/> </baseAddresses> </host> </service> </services> <behaviors> <serviceBehaviors> <behavior name="CertificateBehavior"> <serviceCredentials> <serviceCertificate storeLocation="LocalMachine" x509FindType="FindBySubjectName" findValue="server.mydomain.com"/> </serviceCredentials> </behavior> </serviceBehaviors> </behaviors> <bindings> <customBinding> <binding name="SecureConfig"> <security authenticationMode="MutualCertificate"/> <httpTransport/> </binding> </customBinding> </bindings> </system.serviceModel> </configuration>

• SSIS how to split a single record in to two different records?

  - by Dr. Zim

  I have a Product record that has multiple "zoned" prices, one for each store that sells the product. ProductID int Name string PriceA money PriceB money PriceC money In SQL Server Integration Services, I need to split this in to multiple records: ProductID int Version string // A, B, or C Price money // PriceA if A, PriceB if B, etc. This would be within a Data Flow, I presume as a Transformation between Excel source and OLE DB destination. (Assuming OLE DB is a good destination for MS SQL server).

• mpicc hangs when called from makefile; runs fine as single command

  - by user2518579

  i'm trying to compile WRF (doubt that's relevant) and am having a problem where mpicc will hang when run w/ the compile script. icc and mpif90 have no issues. the compile script is executed w/ #!/bin/csh -f just to be verbose, here's an example. i run the script and get here make[3]: Entering directory `/home/jason/wrf/wrf3.5/external/RSL_LITE' mpicc -DMPI2_SUPPORT -DMPI2_THREAD_SUPPORT -DFSEEKO64_OK -w -O3 -DDM_PARALLEL -DMAX_HISTORY=25 -DNMM_CORE=0 -c rsl_bcast.c and hang. so then i run that line by itself jason@server:~/wrf/wrf3.5$ cd /home/jason/wrf/wrf3.5/external/RSL_LITE jason@server:wrf3.5/external/RSL_LITE$ mpicc -DMPI2_SUPPORT -DMPI2_THREAD_SUPPORT -DFSEEKO64_OK -w -O3 -DDM_PARALLEL -DMAX_HISTORY=25 -DNMM_CORE=0 -c rsl_bcast.c jason@server:wrf3.5/external/RSL_LITE$ compiles instantly. starting the compile script again does the exact same thing but on the next file. i have no idea what to do, and this is basically impossible to google for.

• Multiple Jira instances on a single Tomcat 6 server?

  - by davidhayes

  I have a feeling this is a stupid question but I can't find the answer anywhere... I need to deploy 2 Jira instances on asingle Tomcat server, I can't figure out how to pass in the jira.home property The documentation says I need to:- Add a web context property called 'jira.home' — this property is set in different files depending on your application server. For example, for Tomcat (and therefore for JIRA Standalone), you will need to configure the server.xml file. For other application servers you may need to configure the web.xml file, or set 'Context parameter' options on the deployment UI of the application server, etc. Note that If you have specified a JIRA home in jira-application.properties (ie. the recommended method), it will override your web context property. I was hoping something like this would work. <Context jira.home="d:/jira/data" path="" docBase="D:\Jira\atlassian-jira-enterprise-4.1\dist-tomcat\tomcat-6\atlassian-jira-4.1.war" debug="0"> <Resource name="jdbc/JiraDS" auth="Container" type="javax.sql.DataSource" username="sa" password="*****" driverClassName="net.sourceforge.jtds.jdbc.Driver" url="jdbc:jtds:sqlserver://*****:1433/jira41_519;user=****;password=****" /> <Resource name="UserTransaction" auth="Container" type="javax.transaction.UserTransaction" factory="org.objectweb.jotm.UserTransactionFactory" jotm.timeout="60"/> <Manager pathname=""/> </Context> Any ideas??

I have tried the standard one i.e. ^(?i)M*(D?C{0,3}|C[DM])(L?X{0,3}|X[LC])(V?I{0,3}|I[VX])$, but the problem is it allows null( '') values also. Is there any way around to check is problem?
