  • Extreme Optimization Numerical Libraries for .NET – Part 1 of n

    - by JoshReuben
    While many of my colleagues are fascinated in constructing the ultimate ViewModel or ServiceBus, I feel that this kind of plumbing code is re-invented far too many times – at some point in the near future, it will be out of the box standard infra. How many times have you been to a customer site and built a different variation of the same kind of code frameworks? How many times can you abstract Prism or reliable and discoverable WCF communication? As the bar is raised for whats bundled with the framework and more tasks become declarative, automated and configurable, Information Systems will expose a higher level of abstraction, forcing software engineers to focus on more advanced computer science and algorithmic tasks. I've spent the better half of the past decade building skills in .NET and expanding my mathematical horizons by working through the Schaums guides. In this series I am going to examine how these skillsets come together in the implementation provided by ExtremeOptimization. Download the trial version here: http://www.extremeoptimization.com/downloads.aspx Overview The library implements a set of algorithms for: linear algebra, complex numbers, numerical integration and differentiation, solving equations, optimization, random numbers, regression, ANOVA, statistical distributions, hypothesis tests. EONumLib combines three libraries in one - organized in a consistent namespace hierarchy. Mathematics Library - Extreme.Mathematics namespace Vector and Matrix Library - Extreme.Mathematics.LinearAlgebra namespace Statistics Library - Extreme.Statistics namespace System Requirements -.NET framework 4.0  Mathematics Library The classes are organized into the following namespace hierarchy: Extreme.Mathematics – common data types, exception types, and delegates. Extreme.Mathematics.Calculus - numerical integration and differentiation of functions. Extreme.Mathematics.Curves - points, lines and curves, including polynomials and Chebyshev approximations. curve fitting and interpolation. Extreme.Mathematics.Generic - generic arithmetic & linear algebra. Extreme.Mathematics.EquationSolvers - root finding algorithms. Extreme.Mathematics.LinearAlgebra - vectors , matrices , matrix decompositions, solvers for simultaneous linear equations and least squares. Extreme.Mathematics.Optimization – multi-d function optimization + linear programming. Extreme.Mathematics.SignalProcessing - one and two-dimensional discrete Fourier transforms.

  • Windows 8&ndash;Custom WinRT components and WinJS

    - by Jonas Bush
    Wow, I’m still alive! I installed the RTM of Windows 8 when it became available, and in the last few days have started taking a look at writing a windows 8 app using HTML/JS, which in and of itself is a weird thing. I don’t think that windows developers of 10 years ago would’ve thought something like this would have ever come about. As I was working on this, I ran across a problem, found the solution, and thought I’d blog about it to try and kick start me back into blogging. I already answered my own question on Stack Overflow, but will explain here. I needed to create a custom WinRT component to do some stuff that I either wouldn’t be able to or didn’t know how to do with the javascript libraries available to me. I had a javascript class defined like this: WinJS.Namespace.define("MyApp", { MyClass: WinJS.Class.define(function() { //constructor function }, { /*instance members*/ }, { /*static members*/ }) }); This gives me an object I can access in javascript: var foo = new MyApp.MyClass(); I created my WinRT component like this: namespace MyApp { public sealed class SomeClass { public int SomeMethod() { return 42; } } }   With the thought that from my javascript, I’d be able to do this: var foo = new MyApp.MyClass(); var bar = new MyApp.SomeClass(); //from WinRT component foo.SomeProperty = bar.SomeMethod();   When I tried this, I got the following error when trying to construct MyApp.MyClass (the object defined in Javascript) 0x800a01bd - Javascript runtime error: Object doesn't support this action. I puzzled for a bit, then noticed while debugging that my “MyApp” namespace didn’t have anything in it other than the WinRT component. I changed my WinRT component to this: namespace MyAppUtils { public sealed class SomeClass { //etc } } And after this, everything was fine. So, lesson learned: If you’re using Javascript and create a custom WinRT component, make sure that the WinRT component is in a namespace all its own. Not sure why this happens, and if I find out why or if MS says something about this somewhere, I’ll come back and update this.

  • Which is better: many class definitions in the same file or every class definition in a separate file?

    - by Javed Akram
    Which is better: many class definitions in same file or every class definition in separate file? Examples: 1) Many classes in same file. Say, myManyClasses.cs: namespace myPack { class myClass1() { } class myClass2() { } class myClass3() { } . . . } 2) Every class in separate file: myClass1.cs namespace myPack { class myClass1() { } } myClass2.cs namespace myPack { class myClass2() { } } . . .

  • Including Microsoft.XNA.Framework.Input.Touch in a project?

    - by steven_desu
    So after running through tutorials by both Microsoft and www.xnadevelopment.com I feel very confident in my ability to get to work on my first game using the XNA Framework. I've manipulated sprites, added audio, changed game states, and even went a step further to apply the knowledge I had and figure out how to make animations and basic 2-dimensional physics (including impulses, force, acceleration, and speed calculations) But then shortly into the project I hit a curious bump that I've been unable to figure out. In wanting to implement menus, pause screens, and several different aspects of play (a "pre-level" prep screen, the level itself, and a screen after the level to review how well you did) I took a look at Microsoft's Game State Management sample. I understood the concept, although it was admittedly quite a lot to take in. Not wanting to recreate the entire concept by scratch (after all- what purpose would that serve?) I tried copying and pasting the sample code into my own ScreenManager class (as well as InputState and GameScreen classes) to try and borrow their ingenuity. When I did this, however, my project stopped compiling. I was getting the following error: The type or namespace name 'Touch' does not exist in the namespace 'Microsoft.Xna.Framework.Input' (are you missing an assembly reference?) Having read through their sample code already, I realized that this namespace and every function and class within it could be safely ripped from the code without losing functionality. It's a namespace simply for integrating with touchscreen devices (presumably Windows Phone 7, but maybe also tablets). But then I began to wonder- how come Microsoft's sample compiled but mine didn't? I copied their code exactly so there must be a setting somewhere that I need to change in Visual Studio in order to correct this. I tried creating a new project as a Windows Phone 7 game rather than a Windows game, however that only forced it to compile to a Windows Phone emulator and denied me the ability to change the resolution and other features which I clearly had the power to do in the sample code. So my question is simple - how do I properly use the namespace Microsoft.XNA.Framework.Input.Touch?

  • Different Service behaviors per endpoint

    - by Preben Huybrechts
    The situation We are implementing different sort of security on some WCF service. ClientCertificate, UserName & Password and Anonymous. We have 2 ServiceBehaviorConfigurations, one for httpBinding and one for wsHttpBinding. (We have custom authorization policies for claim based security) As a requirement we need different endpoints for each service. 3 endpoints with httpBinding and 1 with wsHttpBinding. Example for one service: basicHttpBinding : Anonymous basicHttpBinding : UserNameAndPassword basicHttpBinding : BasicSsl wsHttpBinding : BasicSsl The Problem Part 1: We cannot specify the same service twice, once with the http service configuration and once with the wsHttp service configuration. Part 2: We cannot specify service behaviors on an endpoint. (Throws and exception, No endpoint behavior was found... Service behaviors cant be set to endpoint behaviours) The Config For part 1: <services> <service name="Namespace.MyService" behaviorConfiguration="securityBehavior"> <endpoint address="http://server:94/MyService.svc/Anonymous" contract="Namespace.IMyService" binding="basicHttpBinding" bindingConfiguration="Anonymous"> </endpoint> <endpoint address="http://server:94/MyService.svc/UserNameAndPassword" contract="Namespace.IMyService" binding="basicHttpBinding" bindingConfiguration="UserNameAndPassword"> </endpoint> <endpoint address="https://server/MyService.svc/BasicSsl" contract="Namespace.IMyService" binding="basicHttpBinding" bindingConfiguration="BasicSecured"> </endpoint> </service> <service name="Namespace.MyService" behaviorConfiguration="wsHttpCertificateBehavior"> <endpoint address="https://server/MyService.svc/ClientCert" contract="Namespace.IMyService" binding="wsHttpBinding" bindingConfiguration="ClientCert"/> </service> </services> Service Behavior configuration: <serviceBehaviors> <behavior name="securityBehavior"> <serviceAuthorization serviceAuthorizationManagerType="Namespace.AdamAuthorizationManager,Assembly"> <authorizationPolicies> <add policyType="Namespace.AdamAuthorizationManager,Assembly" /> </authorizationPolicies> </serviceAuthorization> </behavior> <behavior name="wsHttpCertificateBehavior"> <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true"/> <serviceAuthorization serviceAuthorizationManagerType="Namespace.AdamAuthorizationManager,Assembly"> <authorizationPolicies> <add policyType="Namespace.AdamAuthorizationManager,Assembly" /> </authorizationPolicies> </serviceAuthorization> <serviceCredentials> <clientCertificate> <authentication certificateValidationMode="PeerOrChainTrust" revocationMode="NoCheck"/> </clientCertificate> <serviceCertificate findValue="CN=CertSubject"/> </serviceCredentials> </behavior> How can we specify a different service behaviour on the WsHttpBinding endpoint? Or how can we apply our authorization policy in a different way for wsHttpBinding then basicHttpBinding. We would use endpoint behavior but we can't specify our authorization policy on an endpoint behavior

  • Boost's "cstdint" Usage

    - by patt0h
    Boost's C99 stdint implementation is awfully handy. One thing bugs me, though. They dump all of their typedefs into the boost namespace. This leaves me with three choices when using this facility: Use "using namespace boost" Use "using boost::[u]<type><width>_t" Explicitly refer to the target type with the boost:: prefix; e.g., boost::uint32_t foo = 0; Option ? 1 kind of defeats the point of namespaces. Even if used within local scope (e.g., within a function), things like function arguments still have to be prefixed like option ? 3. Option ? 2 is better, but there are a bunch of these types, so it can get noisy. Option ? 3 adds an extreme level of noise; the boost:: prefix is often = to the length of the type in question. My question is: What would be the most elegant way to bring all of these types into the global namespace? Should I just write a wrapper around boost/cstdint.hpp that utilizes option ? 2 and be done with it? Also, wrapping the header like so didn't work on VC++ 10 (problems with standard library headers): namespace Foo { #include <boost/cstdint.hpp> using namespace boost; } using namespace Foo; Even if it did work, I guess it would cause ambiguity problems with the ::boost namespace.

  • Exceptional C++[Bug]?

    - by gautam kumar
    I have been reading Exceptional C++ by Herb Sutter. On reaching Item 32 I found the following namespace A { struct X; struct Y; void f( int ); void g( X ); } namespace B { void f( int i ) { f( i ); // which f()? } } This f() calls itself, with infinite recursion. The reason is that the only visible f() is B::f() itself. There is another function with signature f(int), namely the one in namespace A. If B had written "using namespace A;" or "using A::f;", then A::f(int) would have been visible as a candidate when looking up f(int), and the f(i) call would have been ambiguous between A::f(int) and B::f(int). Since B did not bring A::f(int) into scope, however, only B::f(int) can be considered, so the call unambiguously resolves to B::f(int). But when I did the following.. namespace A { struct X; struct Y; void f( int ); void g( X ); } namespace B { using namespace A; void f( int i ) { f( i ); // No error, why? } } That means Herb Sutter has got it all wrong? If not why dont I get an error?

  • Where to add an overloaded operator for the tr1::array?

    - by phlipsy
    Since I need to add an operator& for the std::tr1::array<bool, N> I wrote the following lines template<std::size_t N> std::tr1::array<bool, N> operator& (const std::tr1::array<bool, N>& a, const std::tr1::array<bool, N>& b) { std::tr1::array<bool, N> result; std::transform(a.begin(), a.end(), b.begin(), result.begin(), std::logical_and<bool>()); return result; } Now I don't know in which namespace I've to put this function. I considered the std namespace as a restricted area. Only total specialization and overloaded function templates are allowed to be added by the user. Putting it into the global namespace isn't "allowed" either in order to prevent pollution of the global namespace and clashes with other declarations. And finally putting this function into the namespace of the project doesn't work since the compiler won't find it there. What had I best do? I don't want to write a new array class putted into the project namespace. Because in this case the compiler would find the right namespace via argument dependent name lookup. Or is this the only possible way because writing a new operator for existing classes means extending their interfaces and this isn't allowed either for standard classes?

  • MVC2 Areas and Controller 404

    - by CodeGrue
    My project namespace is MyProject.MVC So my controllers, which are segregated into Areas, are in this namespace: MyProject.MVC.Areas.AreaName But when I try to access a controller action in this namespace, I get a 404 error: http://MySite/AreaName/Action/View If I "remove" the MVC portion from the namespace on my controllers, everything works correctly. MyProject.Areas.AreaName Could I have things wired incorrectly or is this an issues with MVC2 Areas?

  • Design pattern question: encapsulation or inheritance

    - by Matt
    Hey all, I have a question I have been toiling over for quite a while. I am building a templating engine with two main classes Template.php and Tag.php, with a bunch of extension classes like Img.php and String.php. The program works like this: A Template object creates a Tag objects. Each tag object determines which extension class (img, string, etc.) to implement. The point of the Tag class is to provide helper functions for each extension class such as wrap('div'), addClass('slideshow'), etc. Each Img or String class is used to render code specific to what is required, so $Img->render() would give something like <img src='blah.jpg' /> My Question is: Should I encapsulate all extension functionality within the Tag object like so: Tag.php function __construct($namespace, $args) { // Sort out namespace to determine which extension to call $this->extension = new $namespace($this); // Pass in Tag object so it can be used within extension return $this; // Tag object } function render() { return $this->extension->render(); } Img.php function __construct(Tag $T) { $args = $T->getArgs(); $T->addClass('img'); } function render() { return '<img src="blah.jpg" />'; } Usage: $T = new Tag("img", array(...); $T->render(); .... or should I create more of an inheritance structure because "Img is a Tag" Tag.php public static create($namespace, $args) { // Sort out namespace to determine which extension to call return new $namespace($args); } Img.php class Img extends Tag { function __construct($args) { // Determine namespace then call create tag $T = parent::__construct($namespace, $args); } function render() { return '<img src="blah.jpg" />'; } } Usage: $Img = Tag::create('img', array(...)); $Img->render(); One thing I do need is a common interface for creating custom tags, ie I can instantiate Img(...) then instantiate String(...), I do need to instantiate each extension using Tag. I know this is somewhat vague of a question, I'm hoping some of you have dealt with this in the past and can foresee certain issues with choosing each design pattern. If you have any other suggestions I would love to hear them. Thanks! Matt Mueller

  • How do you manage the namespaces of your extension methods?

    - by Robert Harvey
    Do you use a global, catchall namespace for all of your extension methods, or do you put the extension methods in the same namespace as the class(es) they extend? Or do you use some other method, like an application or library-specific namespace? EDIT: I ask because I have a need to extend System.Security.Principal.IIdentity, and putting the extension method in the System.Security.Principal namespace seems to make sense, but I've never seen it done this way.

  • WMI Rights required to read root\MicrosoftIISv2 in IIS7 with IIS6 compatibility mode

    - by JoeBilly
    I need to manage my IIS7 (Windows Server 2008) remotely with a WMI IIS6 API. So I added the IIS6 WMI Compatibility and IIS6 Metabase Compatibility roles to access the root\MicrosoftIIsv2 namespace. I have a domain account which is not administrator on the remote machine ; with this right, everything is ok. I configured these rights for my domain account to access the root\MicrosoftIIsv2 WMI namespace remotely ; note that these rights work perfectly on a IIS6 and Windows Server 2003 : DCOM : Account in Distributed COM Users Remote & local access to DCOM WMI : Root\CIMV2 (I need access here too) Execute methods, Enable Account, Remote Enable Root\Default (I need access here too) Execute methods, Enable Account, Remote Enable Root\MicrosoftIISv2 Execute methods, Enable Account, Provider Write, Remote Enable IIS Metabase (Metabase Explorer) : LM Full Control (W3SVC inherits these permissions) I tried to give some access on C:\Windows\System32\inetsrv too ; don't know if needed. My issue is : I can't list the IIS WebSites (\root\MicrosoftIISv2:IIsWebServerSetting.Name="W3SVC/*"). I don't get an 'access denied' but nothing is returned. My API and powershell tests can connect and execute queries in the root\MicrosoftIISv2 namespace I can read the IIsComputer class ex: Get-WmiObject IIsComputer -namespace "ROOT\MicrosoftIISv2" -authentication PacketPrivacy | SELECT * I can't read the IIsWebServerSetting, IIsWebServer ... to list the WebSites : the query returns an empty collection ex: Get-WmiObject IIsWebServerSetting -namespace "ROOT\MicrosoftIISv2" -authentication PacketPrivacy | SELECT ServerComment All queries work perfectly if the account is administrator as already said I am using PacketPrivacy authentication FI: I got a Warning Event 5605 with the Administrator right or not, that does not seem to have an impact : The root\MicrosoftIISv2 namespace is marked with the RequiresEncryption flag. Access to this namespace might be denied if the script or application does not have the appropriate authentication level. Change the authentication level to Pkt_Privacy and run the script or application again Ok, I have some more informations, when I use IIS 6 Metabase Explorer with my administrator account I can see the rights are correctly inherited for my non-administrator account. But when I try to connect using my non-administrator account, I can list the LM node, but get an "access denied, failed to get a key's data" when I try to browse the child nodes. I'll check further. I tried to Trace the WMI Activity, and everything seems OK ; this tends to confirm that the problem lies in IIS Rights.

In this blog series we will review an existing OpenStack setup using the Oracle OpenStack Tech Preview and explain the different network components through use cases and examples. The goal is to show how the different pieces come together and provide a bigger picture view of the network architecture in OpenStack. This can be very helpful to users making their first steps in OpenStack or anyone wishes to understand how networking works in this environment.  We will go through the basics first and build the examples as we go. According to the recent Icehouse user survey and the one before it, Neutron with Open vSwitch plug-in is the most widely used network setup both in production and in POCs (in terms of number of customers) and so in this blog series we will analyze this specific OpenStack networking setup. As we know there are many options to setup OpenStack networking and while Neturon + Open vSwitch is the most popular setup there is no claim that it is either best or the most efficient option. Neutron + Open vSwitch is an example, one which provides a good starting point for anyone interested in understanding OpenStack networking. Even if you are using different kind of network setup such as different Neutron plug-in or even not using Neutron at all this will still be a good starting point to understand the network architecture in OpenStack. The setup we are using for the examples is the one used in the Oracle OpenStack Tech Preview. Installing it is simple and it would be helpful to have it as reference. In this setup we use eth2 on all servers for VM network, all VM traffic will be flowing through this interface.The Oracle OpenStack Tech Preview is using VLANs for L2 isolation to provide tenant and network isolation. The following diagram shows how we have configured our deployment: This first post is a bit long and will focus on some basic concepts in OpenStack networking. The components we will be discussing are Open vSwitch, network namespaces, Linux bridge and veth pairs. Note that this is not meant to be a comprehensive review of these components, it is meant to describe the component as much as needed to understand OpenStack network architecture. All the components described here can be further explored using other resources. Open vSwitch (OVS) In the Oracle OpenStack Tech Preview OVS is used to connect virtual machines to the physical port (in our case eth2) as shown in the deployment diagram. OVS contains bridges and ports, the OVS bridges are different from the Linux bridge (controlled by the brctl command) which are also used in this setup. To get started let’s view the OVS structure, use the following command: # ovs-vsctl show 7ec51567-ab42-49e8-906d-b854309c9edf     Bridge br-int         Port br-int             Interface br-int type: internal         Port "int-br-eth2"             Interface "int-br-eth2"     Bridge "br-eth2"         Port "br-eth2"             Interface "br-eth2" type: internal         Port "eth2"             Interface "eth2"         Port "phy-br-eth2"             Interface "phy-br-eth2" ovs_version: "1.11.0" We see a standard post deployment OVS on a compute node with two bridges and several ports hanging off of each of them. The example above is a compute node without any VMs, we can see that the physical port eth2 is connected to a bridge called “br-eth2”. We also see two ports "int-br-eth2" and "phy-br-eth2" which are actually a veth pair and form virtual wire between the two bridges, veth pairs are discussed later in this post. When a virtual machine is created a port is created on one the br-int bridge and this port is eventually connected to the virtual machine (we will discuss the exact connectivity later in the series). Here is how OVS looks after a VM was launched: # ovs-vsctl show efd98c87-dc62-422d-8f73-a68c2a14e73d     Bridge br-int         Port "int-br-eth2"             Interface "int-br-eth2"         Port br-int             Interface br-int type: internal         Port "qvocb64ea96-9f" tag: 1             Interface "qvocb64ea96-9f"     Bridge "br-eth2"         Port "phy-br-eth2"             Interface "phy-br-eth2"         Port "br-eth2"             Interface "br-eth2" type: internal         Port "eth2"             Interface "eth2" ovs_version: "1.11.0" Bridge "br-int" now has a new port "qvocb64ea96-9f" which connects to the VM and tagged with VLAN 1. Every VM which will be launched will add a port on the “br-int” bridge for every network interface the VM has. Another useful command on OVS is dump-flows for example: # ovs-ofctl dump-flows br-int NXST_FLOW reply (xid=0x4): cookie=0x0, duration=735.544s, table=0, n_packets=70, n_bytes=9976, idle_age=17, priority=3,in_port=1,dl_vlan=1000 actions=mod_vlan_vid:1,NORMAL cookie=0x0, duration=76679.786s, table=0, n_packets=0, n_bytes=0, idle_age=65534, hard_age=65534, priority=2,in_port=1 actions=drop cookie=0x0, duration=76681.36s, table=0, n_packets=68, n_bytes=7950, idle_age=17, hard_age=65534, priority=1 actions=NORMAL As we see the port which is connected to the VM has the VLAN tag 1. However the port on the VM network (eth2) will be using tag 1000. OVS is modifying the vlan as the packet flow from the VM to the physical interface. In OpenStack the Open vSwitch agent takes care of programming the flows in Open vSwitch so the users do not have to deal with this at all. If you wish to learn more about how to program the Open vSwitch you can read more about it at http://openvswitch.org looking at the documentation describing the ovs-ofctl command. Network Namespaces (netns) Network namespaces is a very cool Linux feature can be used for many purposes and is heavily used in OpenStack networking. Network namespaces are isolated containers which can hold a network configuration and is not seen from outside of the namespace. A network namespace can be used to encapsulate specific network functionality or provide a network service in isolation as well as simply help to organize a complicated network setup. Using the Oracle OpenStack Tech Preview we are using the latest Unbreakable Enterprise Kernel R3 (UEK3), this kernel provides a complete support for netns. Let's see how namespaces work through couple of examples to control network namespaces we use the ip netns command: Defining a new namespace: # ip netns add my-ns # ip netns list my-ns As mentioned the namespace is an isolated container, we can perform all the normal actions in the namespace context using the exec command for example running the ifconfig command: # ip netns exec my-ns ifconfig -a lo        Link encap:Local Loopback           LOOPBACK  MTU:16436 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) We can run every command in the namespace context, this is especially useful for debug using tcpdump command, we can ping or ssh or define iptables all within the namespace. Connecting the namespace to the outside world: There are various ways to connect into a namespaces and between namespaces we will focus on how this is done in OpenStack. OpenStack uses a combination of Open vSwitch and network namespaces. OVS defines the interfaces and then we can add those interfaces to namespace. So first let's add a bridge to OVS: # ovs-vsctl add-br my-bridge Now let's add a port on the OVS and make it internal: # ovs-vsctl add-port my-bridge my-port # ovs-vsctl set Interface my-port type=internal And let's connect it into the namespace: # ip link set my-port netns my-ns Looking inside the namespace: # ip netns exec my-ns ifconfig -a lo        Link encap:Local Loopback           LOOPBACK  MTU:65536 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) my-port   Link encap:Ethernet HWaddr 22:04:45:E2:85:21           BROADCAST  MTU:1500 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) Now we can add more ports to the OVS bridge and connect it to other namespaces or other device like physical interfaces. Neutron is using network namespaces to implement network services such as DCHP, routing, gateway, firewall, load balance and more. In the next post we will go into this in further details. Linux Bridge and veth pairs Linux bridge is used to connect the port from OVS to the VM. Every port goes from the OVS bridge to a Linux bridge and from there to the VM. The reason for using regular Linux bridges is for security groups’ enforcement. Security groups are implemented using iptables and iptables can only be applied to Linux bridges and not to OVS bridges. Veth pairs are used extensively throughout the network setup in OpenStack and are also a good tool to debug a network problem. Veth pairs are simply a virtual wire and so veths always come in pairs. Typically one side of the veth pair will connect to a bridge and the other side to another bridge or simply left as a usable interface. In this example we will create some veth pairs, connect them to bridges and test connectivity. This example is using regular Linux server and not an OpenStack node: Creating a veth pair, note that we define names for both ends: # ip link add veth0 type veth peer name veth1 # ifconfig -a . . veth0     Link encap:Ethernet HWaddr 5E:2C:E6:03:D0:17           BROADCAST MULTICAST  MTU:1500 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) veth1     Link encap:Ethernet HWaddr E6:B6:E2:6D:42:B8           BROADCAST MULTICAST  MTU:1500 Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b) . . To make the example more meaningful this we will create the following setup: veth0 => veth1 => br-eth3 => eth3 ======> eth2 on another Linux server br-eth3 – a regular Linux bridge which will be connected to veth1 and eth3 eth3 – a physical interface with no IP on it, connected to a private network eth2 – a physical interface on the remote Linux box connected to the private network and configured with the IP of 50.50.50.1 Once we create the setup we will ping 50.50.50.1 (the remote IP) through veth0 to test that the connection is up: # brctl addbr br-eth3 # brctl addif br-eth3 eth3 # brctl addif br-eth3 veth1 # brctl show bridge name     bridge id               STP enabled     interfaces br-eth3         8000.00505682e7f6       no              eth3                                                         veth1 # ifconfig veth0 50.50.50.50 # ping -I veth0 50.50.50.51 PING 50.50.50.51 (50.50.50.51) from 50.50.50.50 veth0: 56(84) bytes of data. 64 bytes from 50.50.50.51: icmp_seq=1 ttl=64 time=0.454 ms 64 bytes from 50.50.50.51: icmp_seq=2 ttl=64 time=0.298 ms When the naming is not as obvious as the previous example and we don't know who are the paired veth interfaces we can use the ethtool command to figure this out. The ethtool command returns an index we can look up using ip link command, for example: # ethtool -S veth1 NIC statistics: peer_ifindex: 12 # ip link . . 12: veth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 Summary That’s all for now, we quickly reviewed OVS, network namespaces, Linux bridges and veth pairs. These components are heavily used in the OpenStack network architecture we are exploring and understanding them well will be very useful when reviewing the different use cases. In the next post we will look at how the OpenStack network is laid out connecting the virtual machines to each other and to the external world. @RonenKofman

  • DualLayout for SharePoint 2010 WCM Quick Start

    - by svdoever
    DualLayout for SharePoint 2010 WCM is a solution to provide you with complete HTML freedom in your SharePoint Server 2010 publishing pages. In this post I provide a quick start guide to get you up and running quickly so you can try it out for yourself. This quick start creates a simple HTML5 site with a page to show-case the basics and the power of DualLayout. We will create the site in its own web application. Normally there are many things you have to do to create a clean start point for your SharePoint 2010 WCM site. All those steps will be provided in later posts. For now we want to give you the minimal set of steps to take to get DualLayout working on your machine. Create an authenticated web application with hostheader cms.html5demo.local on port 80 for the cms side of the site. Click the Create Site Collection link on the Application Created dialog box and create a Site Collection based on the Publishing Portal site template. Before we can click the site link in the Top-Level Site Successfully Created dialog we need to add the new host header cms.html5demo.local to the hosts file. Add the following line to the hosts file: 127.0.0.1        cms.html5demo.local Navigate to the site at http://cms.html5demo.local to see the out-of-the-box example Adventure Works publishing site. Download and add the DualLayout solution package designfactory.duallayout.sps2010.trial.1.2.0.0.wsp to the farm’s solution store: On the Start menu, click All Programs. Click Microsoft SharePoint 2010 Products. Click SharePoint 2010 Management Shell. At the Windows PowerShell command prompt, type the following command:Add-SPSolution -LiteralPath designfactory.duallayout.sps2010.trial.1.2.0.0.wsp In SharePoint 2010 Central Administration deploy the solution to the web application http://cms.html5demo.local. Navigate to the site at http://cms.html5demo.local, and in the Site Settings screen select Site Collection Administration > Site collection features and activate the following feature: Open the site http://cms.html5demo.local in SharePoint Designer 2010. Create a view-mode masterpage html5simple.master with the following code: html5simple.master <%@ Master language="C#" %> <%@ Register Tagprefix="SharePointWebControls" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Register TagPrefix="sdl" Namespace="DesignFactory.DualLayout" Assembly="DesignFactory.DualLayout, Version=1.2.0.0, Culture=neutral, PublicKeyToken=077f92bbf864a536" %>   <!DOCTYPE html> <html class="no-js">       <head>         <meta charset="utf-8" />         <meta http-equiv="X-UA-Compatible" content="IE=Edge" />         <title><SharePointWebControls:FieldValue FieldName="Title" runat="server"/></title>           <script type="text/javascript">             document.createElement('header');             document.createElement('nav');             document.createElement('article');             document.createElement('hgroup');             document.createElement('aside');             document.createElement('section');             document.createElement('footer');             document.createElement('figure');             document.createElement('time');         </script>           <asp:ContentPlaceHolder id="PlaceHolderAdditionalPageHead" runat="server"/>     </head>          <body>                  <header>             <div class="logo">Logo</div>             <h1>SiteTitle</h1>             <nav>                 <a href="#">SiteMenu 1</a>                 <a href="#">SiteMenu 2</a>                 <a href="#">SiteMenu 3</a>                 <a href="#">SiteMenu 4</a>                 <a href="#">SiteMenu 5</a>                 <sdl:SwitchToWcmModeLinkButton runat="server" Text="…"/>             </nav>             <div class="tagline">Tagline</div>             <form>                 <label>Zoek</label>                 <input type="text" placeholder="Voer een zoekterm in...">                 <button>Zoek</button>                             </form>           </header>                  <div class="content">             <div class="pageContent">                 <asp:ContentPlaceHolder id="PlaceHolderMain" runat="server" />             </div>         </div>              <footer>             <nav>                 <ul>                     <li><a href="#">FooterMenu 1</a></li>                     <li><a href="#">FooterMenu 2</a></li>                     <li><a href="#">FooterMenu 3</a></li>                     <li><a href="#">FooterMenu 4</a></li>                     <li><a href="#">FooterMenu 5</a></li>                 </ul>             </nav>             <small>Copyright &copy; 2011 Macaw</small>         </footer>     </body> </html> Note that if no specific WCM-mode master page is specified (html5simple-wcm.master), the default v4.master master page will be used in WCM-mode.

  • typedef declaration syntax

    - by mt_serg
    Some days ago I looked at boost sources and found interesting typedef. There is a code from "boost\detail\none_t.hpp": namespace boost { namespace detail { struct none_helper{}; typedef int none_helper::*none_t ; } // namespace detail } // namespace boost I didn't see syntax like that earlier and can't explain the sense of that. This typedef introduces name "none_t" as pointer to int in boost::detail namespace. What the syntax is? And what difference between "typedef int none_helper::*none_t" and for example "typedef int *none_t" ?

  • Is it possible get the functionality of namespaces inside a class?

    - by CowKingDeluxe
    I have the following code: Public Class Form1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Class What I would like to do is be able to separate the code, similar to the following (which obviously doesn't work): Public Class Form1 Namespace Step1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function End Namespace Namespace Step2 Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Namespace End Class I would like the functionality of namespaces inside of a class, as in something that would let me call Step2.Execute() instead of having to put Step2_ in front of a whole bunch of functions. I don't want to have to create separate classes / modules for step1, step2, etc. Is there a way that I can accomplish namespace functionality from inside a class?

  • Possible Conflict with Class name & Property Name?

    - by coffeeaddict
    If you have a namespace that contains a property in ClassA and a class that has the name of that Property somewhere else in your project and both are in the same namespace this won't cause conflicts will it? So lets say I have a class named Car namespace Dealer { class Vehicle { // the main class that defines vehicle, so this is Dealer.Vehicle (Vehicle.cs) } } and a property over in some other class namespace Dealer { class Dealer { public Vehicle Vehicle { get { return _vehicle; } } } } so for the second it is really this for the property public Dealer.Vehicle Vehicle { get { return _car; } } so now you have Dealer.Vehicle and Dealer.Dealer.Vehicle. Wondering of that would cause a conflict ever. If both those classes are in the same namespace and

  • Creating typed WSDL’s for generic WCF services of the ESB Toolkit

    - by charlie.mott
    source: http://geekswithblogs.net/charliemott Question How do you make it easy for client systems to consume the generic WCF services exposed by the ESB Toolkit using messages that conform to agreed schemas\contracts?  Usually the developer of a system consuming a web service adds a service reference using a WSDL. However, the WSDL’s for the generic services exposed by the ESB Toolkit do not make it easy to develop clients that conform to agreed schemas\contracts. Recommendation Take a copy of the generic WSDL’s and modify it to use the proper contracts. This is very easy.  It will work with the generic on ramps so long as the <part>?</part> wrapping is removed from the WCF adapter configuration in the BizTalk receive locations.  Attempting to create a WSDL where the input and output messages are sent/returned with a <part> wrapper is a nightmare.  I have not managed it.  Consequences I can only see the following consequences of removing the <part> wrapper: ESB Test Client – I needed to modify the out-of-the-box ESB Test Client source code to make it send non-wrapped messages.  Flat file formatted messages – the endpoint will no longer support flat file message formats.  However, even if you needed to support this integration pattern through WCF, you would most-likely want to create a separate receive location anyway with its’ own independently configured XML disassembler pipeline component. Instructions These steps show how to implement a request-response implementation of this. WCF Receive Locations In BizTalk, for the WCF receive location for the ESB on-ramp, set the adapter Message settings\bindings to “UseBodyPath”: Inbound BizTalk message body  = Body Outbound WCF message body = Body Create a WSDL’s for each supported integration use-case Save a copy of the WSDL for the WCF generic receive location above that you intend the client system to use. Give it a name that mirrors the interface agreement (e.g. Esb_SuppliersSearchCommand_wsHttpBinding.wsdl).   Add any xsd schemas files imported below to this same folder.   Edit the WSDL to import schemas For example, this: <xsd:schema targetNamespace=http://microsoft.practices.esb/Imports /> … would become something like: <xsd:schema targetNamespace="http://microsoft.practices.esb/Imports">     <xsd:import schemaLocation="SupplierSearchCommand_V1.xsd"                            namespace="http://schemas.acme.co.uk/suppliersearchcommand/1.0"/>     <xsd:import  schemaLocation="SuppliersDocument_V1.xsd"                              namespace="http://schemas.acme.co.uk/suppliersdocument/1.0"/>     <xsd:import schemaLocation="Types\Supplier_V1.xsd"                              namespace="http://schemas.acme.co.uk/types/supplier/1.0"/>     <xsd:import  schemaLocation="GovTalk\bs7666-v2-0.xsd"                               namespace="http://www.govtalk.gov.uk/people/bs7666"/>     <xsd:import  schemaLocation="GovTalk\CommonSimpleTypes-v1-3.xsd"                             namespace="http://www.govtalk.gov.uk/core"/>     <xsd:import  schemaLocation="GovTalk\AddressTypes-v2-0.xsd"                              namespace="http://www.govtalk.gov.uk/people/AddressAndPersonalDetails"/> </xsd:schema> Modify the Input and Output message For example, this: <wsdl:message name="ProcessRequestResponse_SubmitRequestResponse_InputMessage">   <wsdl:part name="part" type="xsd:anyType"/> </wsdl:message> <wsdl:message name="ProcessRequestResponse_SubmitRequestResponse_OutputMessage">   <wsdl:part name="part" type="xsd:anyType"/> </wsdl:message> … would become something like: <wsdl:message name="ProcessRequestResponse_SubmitRequestResponse_InputMessage">   <wsdl:part name="part"                       element="ssc:SupplierSearchEvent"                         xmlns:ssc="http://schemas.acme.co.uk/suppliersearchcommand/1.0" /> </wsdl:message> <wsdl:message name="ProcessRequestResponse_SubmitRequestResponse_OutputMessage">   <wsdl:part name="part"                       element="sd:SuppliersDocument"                       xmlns:sd="http://schemas.acme.co.uk/suppliersdocument/1.0"/> </wsdl:message> This WSDL can now be added as a service reference in client solutions.

  • WPF - How to properly reference a class from XAML

    - by Andy T
    OK, this is a super super noob question, one that I'm almost embarrassed to ask... I want to reference a class in my XAML file. It's a DataTemplateSelector for selecting the right edit template for a DataGrid column. Anyway, I've written the class into my code behind, added the local namespace to the top of top of the XAML, but when I try to reference the class from the XAML, it tells me the class does not exist in the local namespace. I must be missing something really really simple but I just can't understand it... Here's my code. XAML: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:tk="http://schemas.microsoft.com/wpf/2008/toolkit" xmlns:local="clr-namespace:CustomFields" xmlns:col="clr-namespace:System.Collections;assembly=mscorlib" xmlns:sys="clr-namespace:System;assembly=mscorlib" x:Class="CustomFields.MainWindow" x:Name="Window" Title="Define Custom Fields" Width="425" Height="400" MinWidth="425" MinHeight="400"> <Window.Resources> <ResourceDictionary> <local:RangeValuesEditTemplateSelector> blah blah blah... </local:RangeValuesEditTemplateSelector> </ResourceDictionary> </Window.Resources> C#: namespace CustomFields { /// /// Interaction logic for MainWindow.xaml /// public partial class MainWindow : Window { public MainWindow() { this.InitializeComponent(); // Insert code required on object creation below this point. } } public class RangeValuesEditTemplateSelector : DataTemplateSelector { public RangeValuesEditTemplateSelector(){ MessageBox.Show("hello"); } } } Any ideas what I'm doing wrong? I thought this should be simple as 1-2-3... Thanks! AT

  • Extension methods conflict

    - by Yochai Timmer
    Lets say I have 2 extension methods to string, in 2 different namespaces: namespace test1 { public static class MyExtensions { public static int TestMethod(this String str) { return 1; } } } namespace test2 { public static class MyExtensions2 { public static int TestMethod(this String str) { return 2; } } } These methods are just for example, they don't really do anything. Now lets consider this piece of code: using System; using test1; using test2; namespace blah { public static class Blah { public Blah() { string a = "test"; int i = a.TestMethod(); //Which one is chosen ? } } } I know that only one of the extension methods will be chosen. Which one will it be ? and why ? How can I choose a certain method from a certain namespace ? Edit: Usually I'd use Namespace.ClassNAME.Method() ... But that just beats the whole idea of extension methods. And I don't think you can use Variable.Namespace.Method()

  • Viewing namespaced global variables in Visual Studio debugger?

    - by Chris
    When debugging a non-managed C++ project in Visual Studio 2008, I occasionally want to see the value of a global variable. We don't have a lot of these but those that are there all declared within a namespace called 'global'. e.g. namespace global { int foo; bool bar; ... } The problem is that when the code is stopped at a breakpoint, the default debugging tooltip (from pointing at the variable name) and quickwatch (shift-f9 on the variable name) don't take the namespace into consideration and hence won't work. So for example I can point at 'foo' and nothing comes up. If I shift-f9 on foo, it will bring up the quickwatch, which then says 'CXX0017: Error: symbol "foo" not found'. I can get around that by manually editing the variable name in the quickwatch window to prefix it with "global::" (which is cumbersome considering you have to do it each time you want to quickwatch), but there is no fix for the tooltip that I can work out. Setting the 'default namespace' of the project properties doesn't help. How can I tell the VS debugger to use the namespace that it already knows the variable is declared in (since it has the declaration right there), or, alternatively, tell it a default namespace to look for variables in if it doesn't find them? My google-fu has failed to find an answer. This report lists the same problem, with MS saying it's "by design", but even so I am hoping there is some way to work around it (perhaps with clever use of autoexp.dat?)
