• SEO: Make hashtag links look static

  - by elias94xx

  So I have a website which displays all my content vertically. (like modern websites often do these days). Thus I can't create static links to each section. I'm currently handling the scrolling with javascript. My navigation looks like this. <ul> <li><a href="#services">Services</a></li> <li><a href="#references">References</a></li> <li><a href="#blog">Blog</a></li> <li><a href="#contact">Contact</a></li> </ul> I also created 301 redirect links with htaccess. E.g. /services which leads to /#services. If I were to use them in my navigation, I'd have to trigger the scrolling with the onpopstate event. Thats not really a problem, but would searchengines accept that kind of setup ? I also created a sitemap and submitted it to google, but the indexing is still pending.

• Strategy for hosting 700+ domains, each with static HTML site

  - by jonschlinkert

  I have a portfolio of more than 700 domain names, and ideally I'd like to put up a single-page HTML/CSS/JavaScript webpage for each domain. Is there a system/strategy/workflow that will allow me to: Automate the deployment of new websites, quickly and easily without having to manually initiate each new website in an admin panel. For instance, I've seen dropbox-based solutions that claim to make it simple to setup new websites on your dropbox account, but you still have to set each one up in an admin interface first. It would be so much easier to have a folder naming convention that allowed the user to easily clone/copy/duplicate sites inside their Dropbox App folder (https://www.dropbox.com/developers/blog/23) to create new ones. Sounds interesting, however... It's easy to managing CNAMEs on the registrar-side, is there a way to quickly associate CNAMEs with new websites, maybe gh-pages-style (https://help.github.com/articles/setting-up-a-custom-domain-with-pages)? With GitHub's gh-pages, all you have to do is drop a file called CNAME into your repo, with the domain name you want associated with the repo inside the file. gh-pages isn't a good solution for what I'm doing though unfortunately. I'm also a front-end developer, specializing in rapid web development and "front-end build systems", so I building and maintaining static assets for hundreds of sites is no problem. It's the hosting-side that I really struggle with. Any suggestions?

• Moving from a static site to a CMS with new URLs and meta-data for pages

  - by Chris J

  Hi I am in the process of rebuilding a site from static pages to a CMS which will be using mod_rewrite to generate new page URLs. In this process our marketing people and myself have decided to tidy up the descriptions, keywords and titles. Eg: a page which who's URL is currently "website-name/about_us.html" and has a title of "website-name - something not quite page specific" will change to "website-name/about-us/" and title: "about us - website-name" and may have a few keywords and the description changed. Our goal with updating the meta data is to improve our page rankings and try to keep in line with some best practices for SEO. Though our current page rankings are quite good in many aspects, there is room for improvement. All of the pages will also have content changes (like rearranging heading tags, new menu on all pages, new content in footer, extra pieces of dynamic content relating to other pages). In this new site process I plan to use 301 redirects for all the old URLs pointing to the new URLs. My question is what can I expect to happen to the page rankings in Google, in the sort term and long term? Will this be like kicking off a new site which will have to build up trust over time or will the original page rankings have affect?

• How can I use WCF with only basichttpbinding, SSL and Basic Authentication in IIS?

  - by Tim

  Hello, Is it possible to setup a WCF service with SSL and Basic Authentication in IIS using only BasicHttpBinding-binding? (I can’t use the wsHttpBinding-binding) The site is hosted on IIS 7, with the following authentication set up: - Anonymous access: off - Basic authentication: on - Integrated Windows authentication: off !! Service Config: <services> <service name="NameSpace.SomeService"> <host> <baseAddresses> <add baseAddress="https://hostname/SomeService/" /> </baseAddresses> </host> <!-- Service Endpoints --> <endpoint address="" binding="basicHttpBinding" bindingNamespace="http://hostname/SomeMethodName/1" contract="NameSpace.ISomeInterfaceService" name="Default" /> <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior> <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> <serviceMetadata httpsGetEnabled="true"/> <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> <serviceDebug includeExceptionDetailInFaults="false"/> <exceptionShielding/> </behavior> </serviceBehaviors> </behaviors> I tried 2 types of bindings with two different errors: 1 - IIS Error: 'Could not find a base address that matches scheme http for the endpoint with binding BasicHttpBinding. Registered base address schemes are [https]. <bindings> <basicHttpBinding> <binding> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Basic"/> </security> </binding> </basicHttpBinding> </bindings> 2 - IIS Error: Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service. <bindings> <basicHttpBinding> <binding> <security mode="Transport"> <transport clientCredentialType="Basic"/> </security> </binding> </basicHttpBinding> </bindings> Does somebody know how to configure this correctly?

• Silverlight DataGrid set cell IsReadOnly programatically

  - by Brandon Montgomery

  I am binding a data grid to a collection of Task objects. A particular column needs some special rules pertaining to editing: <!--Percent Complete--> <data:DataGridTextColumn Header="%" ElementStyle="{StaticResource RightAlignStyle}" Binding="{Binding PercentComplete, Mode=TwoWay, Converter={StaticResource PercentConverter}}" /> What I want to do is set the IsReadOnly property only for each task's percent complete cell based on a property on the actual Task object. I've tried this: <!--Percent Complete--> <data:DataGridTextColumn Header="%" ElementStyle="{StaticResource RightAlignStyle}" Binding="{Binding PercentComplete, Mode=TwoWay, Converter={StaticResource PercentConverter}}" IsReadOnly={Binding IsNotLocalID} /> but apparently you can't bind to the IsReadOnly property on a data grid column. What is the best way do to do what I am trying to do?

• Run Sinatra via a Rake Task to Generate Static Files?

  - by viatropos

  I'm not sure I can put this correctly but I'll give it a shot. I want to use Sinatra to generate static html files once I am ready to deploy an application, so the resulting final website would be pure static HTML. During development, however, I want everything to be dynamic so I can use Haml and straight Ruby code to make things fast/dry/clear. I don't want to use Jekyll or some of the other static site generators out there because they don't have as much power as Sinatra. So all I basically need to be able to do is run a rake task such as: rake sinatra:generate_static_files. That would run the render commands for Haml and everything else, and the result would be written to files. My question is, how do I do that with Sinatra in a Rake task? Can I do it in a Rake task? The problem is, I don't know how to include the Sinatra::Application in the rake task... The only other way I could think of doing it is using net/http to access a URL that does all of that, but that seems like overkill. Any ideas how on to solve this?

• Is there a cleaner way to Bind property to owner's DataContext?

  - by Dan Bryant

  I have some code that looks like this: <Expander Header="{Binding SelectedSlot.Name}" Visibility="{Binding ShowGroupSlot, Converter={StaticResource BooleanToVisibility}}"> <Controls:GroupPrototypeSlotControl Slot="{Binding DataContext.SelectedSlot, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Expander}}}" /> </Expander> This works, but the ugliness of the Slot Binding bothers me. This is required because the GroupPrototypeSlotControl has a GroupPrototypeViewModel as its DataContext. If I simply use {Binding SelectedSlot}, it attempts to resolve it on the 'child' ViewModel, which fails. I get around this by explicitly looking at the DataContext of my parent control. Is there a cleaner way to do this type of binding?

• Creation of Objects: Constructors or Static Factory Methods

  - by Rachel

  I am going through Effective Java and some of my things which I consider as standard are not suggested by the book, for instance creation of object, I was under the impression that constructors are the best way of doing it and books says we should make use of static factory methods, I am not able to few some advantages and so disadvantages and so am asking this question, here are the benefits of using it. Advantages: One advantage of static factory methods is that, unlike constructors, they have names. A second advantage of static factory methods is that, unlike constructors, they are not required to create a new object each time they’re invoked. A third advantage of static factory methods is that, unlike constructors, they can return an object of any subtype of their return type. A fourth advantage of static factory methods is that they reduce the verbosity of creating parameterized type instances. I am not able to understand this advantage and would appreciate if someone can explain this point Disadvantages: The main disadvantage of providing only static factory methods is that classes without public or protected constructors cannot be subclassed. A second disadvantage of static factory methods is that they are not readily distinguishable from other static methods.I am not getting this point and so would really appreciate some explanation. Reference: Effective Java, Joshua Bloch, Edition 2, pg: 5-10 Also, How to decide to use whether to go for Constructor or Static Factory Method for Object Creation ?

• Using static variables for Strings

  - by Vivart

  below content is taken from Best practice: Writing efficient code but i didn't understand why private static String x = "example"; faster than private static final String x ="example"; Can anybody explain this. Using static variables for Strings When you define static fields (also called class fields) of type String, you can increase application speed by using static variables (not final) instead of constants (final). The opposite is true for primitive data types, such as int. For example, you might create a String object as follows: private static final String x = "example"; For this static constant (denoted by the final keyword), each time that you use the constant, a temporary String instance is created. The compiler eliminates "x" and replaces it with the string "example" in the bytecode, so that the BlackBerry® Java® Virtual Machine performs a hash table lookup each time that you reference "x". In contrast, for a static variable (no final keyword), the String is created once. The BlackBerry JVM performs the hash table lookup only when it initializes "x", so access is faster. private static String x = "example"; You can use public constants (that is, final fields), but you must mark variables as private.

• C++: Static variable inside a constructor, are there any drawbacks or side effects?

  - by doc

  What I want to do: run some prerequisite code whenever instance of the class is going to be used inside a program. This code will check for requiremts etc. and should be run only once. I found that this can be achieved using another object as static variable inside a constructor. Here's an example for a better picture: class Prerequisites { public: Prerequisites() { std::cout << "checking requirements of C, "; std::cout << "registering C in dictionary, etc." << std::endl; } }; class C { public: C() { static Prerequisites prerequisites; std::cout << "normal initialization of C object" << std::endl; } }; What bothers me is that I haven't seen similar use of static variables so far. Are there any drawbacks or side-effects or am I missing something? Or maybe there is a better solution? Any suggestions are welcome.

• Setting custom WCF-binding behaviour via .config file - why doesn't this work?

  I am attempting to insert a custom behavior into my service client, following the example here. I appear to be following all of the steps, but I am getting a ConfigurationErrorsException. Is there anyone more experienced than me who can spot what I'm doing wrong? Here is the entire app.config file. <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <behaviors> <endpointBehaviors> <behavior name="ClientLoggingEndpointBehaviour"> <myLoggerExtension /> </behavior> </endpointBehaviors> </behaviors> <extensions> <behaviorExtensions> <add name="myLoggerExtension" type="ChatClient.ClientLoggingEndpointBehaviourExtension, ChatClient, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"/> </behaviorExtensions> </extensions> <bindings> </bindings> <client> <endpoint behaviorConfiguration="ClientLoggingEndpointBehaviour" name="ChatRoomClientEndpoint" address="http://localhost:8016/ChatRoom" binding="wsDualHttpBinding" contract="ChatRoomLib.IChatRoom" /> </client> </system.serviceModel> </configuration> Here is the exception message: An error occurred creating the configuration section handler for system.serviceModel/behaviors: Extension element 'myLoggerExtension' cannot be added to this element.

• Windows CE: Changing Static IP Address

  - by Bruce Eitman

  A customer contacted me recently and asked me how to change a static IP address at runtime.  Of course this is not something that I know how to do, but with a little bit of research I figure out how to do it. It turns out that the challenge is to request that the adapter update itself with the new IP Address.  Otherwise, the change in IP address is a matter of changing the address in the registry for the adapter.   The registry entry is something like: [HKEY_LOCAL_MACHINE\Comm\LAN90001\Parms\TcpIp]    "EnableDHCP"=dword:0    "IpAddress"="192.168.0.100"     "DefaultGateway"="192.168.0.1"    "Subnetmask"="255.255.255.0" Where LAN90001 would be replace with your adapter name.  I have written quite a few articles about how to modify the registry, including a registry editor that you could use. Requesting that the adapter update itself is a matter of getting a handle to the NDIS driver, and then asking it to refresh the adapter.  The code is: #include <windows.h> #include "winioctl.h" #include "ntddndis.h"   void RebindAdapter( TCHAR *adaptername ) {       HANDLE hNdis;       BOOL fResult = FALSE;       int count;         // Make this function easier to use - hide the need to have two null characters.       int length = wcslen(adaptername);       int AdapterSize = (length + 2) * sizeof( TCHAR );       TCHAR *Adapter = malloc(AdapterSize);       wcscpy( Adapter, adaptername );       Adapter[ length ] = '\0';       Adapter[ length +1 ] = '\0';           hNdis = CreateFile(DD_NDIS_DEVICE_NAME,                   GENERIC_READ | GENERIC_WRITE,                   FILE_SHARE_READ | FILE_SHARE_WRITE,                   NULL,                   OPEN_ALWAYS,                   0,                   NULL);         if (INVALID_HANDLE_VALUE != hNdis)       {             fResult = DeviceIoControl(hNdis,                         IOCTL_NDIS_REBIND_ADAPTER,                         Adapter,                         AdapterSize,                         NULL,                         0,                         &count,                         NULL);             if( !fResult )             {                   RETAILMSG( 1, (TEXT("DeviceIoControl failed %d\n"), GetLastError() ));             }             CloseHandle(hNdis);       }       else       {             RETAILMSG( 1, (TEXT("Failed to open NDIS Handle\n")));       }   }       int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPWSTR    lpCmdLine, int       nCmdShow) {     RebindAdapter( TEXT("LAN90001") );     return 0; }   If you don’t want to write any code, but instead plan to use a registry editor to change the IP Address, then there is a command line utility to do the same thing.  NDISConfig.exe can be used: Ndisconfig adapter rebind LAN90001    Copyright © 2012 – Bruce Eitman All Rights Reserved

• Where does the "mm" come from in GTKmm, glibmm, etc

  - by Cole Johnson

  I understand that the "mm" suffix [in various GTK-associated C++ binding libraries] means "minus minus," but where exactly does it come from? I understand that there is a programming language called "C--," but if there were bindings (and I'm pretty sure I've seen some), they would be suffixed "--". TL;DR: Is there some page on gnu.org that explains the "mm" suffix in various C++ bindings or is it just a de facto standard adopted by the open source community with no reasoning behind it?

• Loading and binding a serialized view model to a WPF window?

  - by generalt

  Hello all. I'm writing a one-window UI for a simple ETL tool. The UI consists of the window, the code behind for the window, a view model for the window, and the business logic. I wanted to provide functionality to the users to save the state of the UI because the content of about 10-12 text boxes will be reused between sessions, but are specific to the user. I figured I could serialize the view model, which contains all the data from the textboxes, and this works fine, but I'm having trouble loading the information in the serialized XML file back into the text boxes. Constructor of window: public ETLWindow() { InitializeComponent(); _viewModel = new ViewModel(); this.DataContext = _viewModel; _viewModel.State = Constants.STATE_IDLE; Loaded += new RoutedEventHandler(MainWindow_Loaded); } XAML: <TextBox x:Name="targetDirectory" IsReadOnly="true" Text="{Binding TargetDatabaseDirectory, UpdateSourceTrigger=PropertyChanged}"/> ViewModel corresponding property: private string _targetDatabaseDirectory; [XmlElement()] public string TargetDatabaseDirectory { get { return _targetDatabaseDirectory; } set { _targetDatabaseDirectory = value; OnPropertyChanged(DataUtilities.General.Utilities.GetPropertyName(() => new ViewModel().TargetDatabaseDirectory)); } Load event in code behind: private void loadState_Click(object sender, RoutedEventArgs e) { string statePath = this.getFilePath(); _viewModel = ViewModel.LoadModel(statePath); } As you can guess, the LoadModel method deserializes the serialized file on the user's drive. I couldn't find much on the web regarding this issue. I know this probably has something to do with my bindings. Is there some way to refresh on the bindings on the XAML after I deserialize the view model? Or perhaps refresh all properties on the view model? Or am I completely insane thinking any of this could be done? Thanks.

• Jupiter Changes Display when using volume key bindings

  - by user87797

  I recently downloaded jupiter on ubuntu 12.04 ASUS U36JC and I noticed that my display would switch from clone to exterior to clone everytime that I used the keys that control the volume. Hit "function volume down" and the screen goes blank, hit "function volume up" and the display come back. This only happens when I am running jupiter and I assume there is a key binding issue, but I don't know how to fix it. No options other than the regular ones show up in the keyboard settings under system tools.

• Dynamic Auto updating (to UI, Grid) binding list in C# Winform?

  - by Dhana

  I'm not even sure if i'm doing this correctly. But basically I have a list of objects that are built out of a class/interface. From there, I am binding the list to a datagrid view that is on a Windows Form (C#) Here the list is a Sync list which will auto update the UI, in this case datagridview. Every thing works fine now, but now i would like to have the List should have an dynamic object, that is the object will have by default two static property (ID, Name), and at run time user will select remaining properties. These should be bind to the data grid. Any update on the list should be auto reflected in the grid. I am aware that, we can use dynamic objects, but i would like to know , how to approach for solution, datagridview.DataSource = myData; // myData is AutoUpdateList<IPersonInfo> Now IPersonInfo is the type of object, need to add dynamic properties for this type at runtime. public class AutoUpdateList<T> : System.ComponentModel.BindingList<T> { private System.ComponentModel.ISynchronizeInvoke _SyncObject; private System.Action<System.ComponentModel.ListChangedEventArgs> _FireEventAction; public AutoUpdateList() : this(null) { } public AutoUpdateList(System.ComponentModel.ISynchronizeInvoke syncObject) { _SyncObject = syncObject; _FireEventAction = FireEvent; } protected override void OnListChanged(System.ComponentModel.ListChangedEventArgs args) { try { if (_SyncObject == null) { FireEvent(args); } else { _SyncObject.Invoke(_FireEventAction, new object[] { args }); } } catch (Exception) { // TODO: Log Here } } private void FireEvent(System.ComponentModel.ListChangedEventArgs args) { base.OnListChanged(args); } } Could you help out on this?

• Can I change the binding source to another source in XAML?

  - by No hay Problema

  Hi guys, I want to do a very simple thing, can you point me on the right direction? I want to change the source in XAML to another object source, let me put you an example: I have a Listview, bound to a "Model A", it has many properties, but one is called "Total". This property is not shown on the View Each ListviewItem has its own source (ItemsSource), BUT, one of the fields should show "Total" from "Model A" Caveat: I am implementing MVVM, so the "Model A" is assigned as a VM DataSource, XAML knows nothing about it. So, in my perfect world the XAML should look like this: <GridViewColumn Header="Total" Width="150"> <GridViewColumn.CellTemplate> <DataTemplate> <Label Content="{Binding Source=<The source of LISTVIEW> Path=Total}"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> I have tried RelativeSource but that points me to the XAML object, I want the source of it, is it possible? Thanks

• Inspection, code review - is it really testing?

  - by user970696

  ISTQB, Wikipedia or other sources classify verification acitivities (reviews etc.) as a static testing, yet other do not. If we can say that peer reviews and inspections are actually a kind of a testing, then a lot of standards do not make sense (consider e.g. ISO which say that validation is done by testing, while verification by checking of work products) - it should at least say dynamic testing for validation, shouldn't it? I am completing master thesis dealing with QA and I must admit that I have never seen worse and more ambiguous and contradicting literature than in this field :/ Do you think (and if so, why) that static testing is a good and justifiable term or should we stick to testing and static checks/analysis?

• Swapping data binding in code

  - by Phil J Pearson

  I have two data-bound text boxes. One is bound to a string and the other to a number. The 'default' binding is set in XAML. Under some circumstances I need to reverse the bindings at runtime (the string is usually a prefix but sometimes it's a suffix). I have the following code in my view model, called when the window is loaded: Binding stringBinding = BindingOperations.GetBinding(view.seqLeft, TextBox.TextProperty); Binding numberBinding = BindingOperations.GetBinding(view.seqRight, TextBox.TextProperty); view.seqLeft.SetBinding(TextBlock.TextProperty, numberBinding); view.seqRight.SetBinding(TextBlock.TextProperty, stringBinding); After that the code loads the properties to which the binding refers. The problem is that the 'new' binding doesn't seem to work. What have I missed? Is there a better way?

• C++ Static Initializer - Is it thread safe

Is there any better way to static initialize stringlist, instead of using a seperate static function (init)?
