• Picking photo from Photochooser or holding hardware back button cause active timers ring

  - by Nznoonee

  This is very strange problem, and all the people I had asked to confirm it said that it takes place. I have a Threading.Timer instance which fires every 15 minutes. And if I call the PhotoChooser view and then select a photo from it, when going back to the calling page my application calls that timer's callback! I tried different timers either it be Timer from Threading namespace or Dispatcher timer. The same happens when being in my app I hold the back button of my device and then choose the app from the list. My application is as plain as it can be - the timer with a callback and method calling PhotoChooser. Could anyone help with solution or workaround please?

• Android TelephonyManager.getNetworkType() returned constant values in bearer speed order?

  - by Rob Shepherd

  TelephonyManager.getNetworkType() returns one of the constant values. It appears that the constant values have an integer order, by possible bearer link speed. I know using constant values used in the following manner is generally bad, however could one use this to determine a basic cutoff for application functionality and have it work between API levels? (in API-v1 there was nothing above 0x03) if( telephonyManager.getNetworkType() > TelephonyManager.NETWORK_TYPE_EDGE ) { return "3G! party on!"; } else if( telephonyManager.getNetworkType() > TelephonyManager.NETWORK_TYPE_UNKNOWN ) { return "2G, OK. just don't go nuts!"; } else { return "No data sorry" }

• load-views when running multiple noir servers

  - by Roth Michaels

  I'm experimenting with using noir to start three servers (each to handle a different aspect of the application). I am trying to do this so that I can run all three servers within one application while developing and easily decouple the project into three different applications for deployment. It is no problem to use noir.server/start and noir.server/stop to run the jetty servers I need. What I'm trying to figure out is some way to call load-views (or something like that) with a different set views for each server so that URI conflicts are handled by the correct defpage.

• OpenGL - drawing 2D polygons shapes with texture

  - by plonkplonk

  I am trying to make a few effects in a C+GL game. So far I draw all my sprites as a quad, and it works. However, I am trying to make a large ring appear at times, with a texture following that ring, as it takes less memory than a quad with the ring texture inside. The type of ring I want to make is not a round-shaped GL mesh ring (the "tube" type) but a "paper" 2D ring. That way I can modify the "width" of the ring, getting more of the effect than a simple quad+ring texture. So far all my attempts have been...kind of ridiculous, as I don't understand GL's coordinates too well (and I can't really understand the available documentation...I am just a designer with no coder help or background. A n00b, basically). glBegin(GL_POLYGON); for(i = 0;i < 360; i += 10){ glTexCoord2f(0, 0); glVertex2f(Cos(i)*(H-10),Sin(i)H); glTexCoord2f(0, HP); glVertex2f(Sin(i)(H-10),Cos(i)*(H-10)); glTexCoord2f(WP, HP); glVertex2f(Cos(i)H,Sin(i)(H-10)); glTexCoord2f(WP, 0); glVertex2f(Sin(i)*H,Cos(i)*H); } glEnd(); This is my last attempt, and it seems to generate a "sunburst" from the right edge of the circle instead of a ring. It's an amusing effect but definitely not what I want. Other results included the circle looking exactly the same as the quad textured (aka drawing a sprite literally) or something that looked like a pop-art filter, by working on this train of thought. Seems like my logic here is entirely flawed, so, what would be the easiest way to obtain such a ring? No need to reply in code, just some guidance for a non-math-skilled user...

• How to set up a home SIP Server/Proxy for multi ring?

  - by zio

  I have a sip account which only allows one device to be registered. When i'm at home I want incoming calls to be able to ring on multiple devices. All of these devices are connected to the local network. I'm guessing the way to do this is using a local server/proxy that would allow multiple registrations which then forwards traffic to/from my sip provider. What a simple way to do this on either OS X, Ubuntu or using some low cost SIP router hardware?

• Which things instantly ring alarm bells when looking at code? [closed]

  - by FinnNk

  I attended a software craftsmanship event a couple of weeks ago and one of the comments made was "I'm sure we all recognize bad code when we see it" and everyone nodded sagely without further discussion. This sort of thing always worries me as there's that truism that everyone thinks they're an above average driver. Although I think I can recognize bad code I'd love to learn more about what other people consider to be code smells as it's rarely discussed in detail on people's blogs and only in a handful of books. In particular I think it'd be interesting to hear about anything that's a code smell in one language but not another. I'll start off with an easy one: Code in source control that has a high proportion of commented out code - why is it there? was it meant to be deleted? is it a half finished piece of work? maybe it shouldn't have been commented out and was only done when someone was testing something out? Personally I find this sort of thing really annoying even if it's just the odd line here and there, but when you see large blocks interspersed with the rest of the code it's totally unacceptable. It's also usually an indication that the rest of the code is likely to be of dubious quality as well.

• Using a Token-ring network card instead of a router (?)

  - by John

  I have cable, and the modem only has 1 network plug-in. They said I could buy my own router if I wanted to hook up two computers to it. I have an IBM Turbo 16/4 Token-Ring PC Card 2, which was in the laptop when I bought it, and the laptop also has the typical network plug (not a PC Card). Is there a way I could run the laptop as a server, and plug my desktop into the laptop, so they both have internet without my having to buy a router? (I realize routers are as cheap as $30.) Both computers run Windows XP Pro SP3. (I also have an 10/100 Etherjet Cardbus card (PC Card)). Thanks.

• Why is creating a ring buffer shared by different processes so hard (in C++), what I am doing wrong?

  - by recipriversexclusion

  I am being especially dense about this but it seems I'm missing an important, basic point or something, since what I want to do should be common: I need to create a fixed-size ring buffer object from a manager process (Process M). This object has write() and read() methods to write/read from the buffer. The read/write methods will be called by independent processes (Process R and W) I have implemented the buffer, SharedBuffer<T&>, it allocates buffer slots in SHM using boost::interprocess and works perfectly within a single process. I have read the answers to this question and that one on SO, as well as asked my own, but I'm still in the dark about how to have different processes access methods from a common object. The Boost doc has an example of creating a vector in SHM, which is very similar to what I want, but I want to instantiate my own class. My current options are: Use placement new, as suggested by Charles B. to my question; however, he cautions that it's not a good idea to put non-POD objects in SHM. But my class needs the read/write methods, how can I handle those? Add an allocator to my class definition, e.g. have SharedBuffer<T&, Alloc> and proceed similarly to the vector example given in boost. This sounds really complicated. Change SharedBuffer to a POD class, i.e. get rid of all the methods. But then how to synchronize reading and writing between processes? What am I missing? Fixed-length ring buffers are very common, so either this problem has a solution or else I'm doing something wrong.

• Set Context User Principal for Customized Authentication in SignalR

  - by Shaun

  Originally posted on: http://geekswithblogs.net/shaunxu/archive/2014/05/27/set-context-user-principal-for-customized-authentication-in-signalr.aspxCurrently I'm working on a single page application project which is built on AngularJS and ASP.NET WebAPI. When I need to implement some features that needs real-time communication and push notifications from server side I decided to use SignalR. SignalR is a project currently developed by Microsoft to build web-based, read-time communication application. You can find it here. With a lot of introductions and guides it's not a difficult task to use SignalR with ASP.NET WebAPI and AngularJS. I followed this and this even though it's based on SignalR 1. But when I tried to implement the authentication for my SignalR I was struggled 2 days and finally I got a solution by myself. This might not be the best one but it actually solved all my problem.   In many articles it's said that you don't need to worry about the authentication of SignalR since it uses the web application authentication. For example if your web application utilizes form authentication, SignalR will use the user principal your web application authentication module resolved, check if the principal exist and authenticated. But in my solution my ASP.NET WebAPI, which is hosting SignalR as well, utilizes OAuth Bearer authentication. So when the SignalR connection was established the context user principal was empty. So I need to authentication and pass the principal by myself.   Firstly I need to create a class which delivered from "AuthorizeAttribute", that will takes the responsible for authenticate when SignalR connection established and any method was invoked. 1: public class QueryStringBearerAuthorizeAttribute : AuthorizeAttribute 2: { 3: public override bool AuthorizeHubConnection(HubDescriptor hubDescriptor, IRequest request) 4: { 5: } 6:  7: public override bool AuthorizeHubMethodInvocation(IHubIncomingInvokerContext hubIncomingInvokerContext, bool appliesToMethod) 8: { 9: } 10: } The method "AuthorizeHubConnection" will be invoked when any SignalR connection was established. And here I'm going to retrieve the Bearer token from query string, try to decrypt and recover the login user's claims. 1: public override bool AuthorizeHubConnection(HubDescriptor hubDescriptor, IRequest request) 2: { 3: var dataProtectionProvider = new DpapiDataProtectionProvider(); 4: var secureDataFormat = new TicketDataFormat(dataProtectionProvider.Create()); 5: // authenticate by using bearer token in query string 6: var token = request.QueryString.Get(WebApiConfig.AuthenticationType); 7: var ticket = secureDataFormat.Unprotect(token); 8: if (ticket != null && ticket.Identity != null && ticket.Identity.IsAuthenticated) 9: { 10: // set the authenticated user principal into environment so that it can be used in the future 11: request.Environment["server.User"] = new ClaimsPrincipal(ticket.Identity); 12: return true; 13: } 14: else 15: { 16: return false; 17: } 18: } In the code above I created "TicketDataFormat" instance, which must be same as the one I used to generate the Bearer token when user logged in. Then I retrieve the token from request query string and unprotect it. If I got a valid ticket with identity and it's authenticated this means it's a valid token. Then I pass the user principal into request's environment property which can be used in nearly future. Since my website was built in AngularJS so the SignalR client was in pure JavaScript, and it's not support to set customized HTTP headers in SignalR JavaScript client, I have to pass the Bearer token through request query string. This is not a restriction of SignalR, but a restriction of WebSocket. For security reason WebSocket doesn't allow client to set customized HTTP headers from browser. Next, I need to implement the authentication logic in method "AuthorizeHubMethodInvocation" which will be invoked when any SignalR method was invoked. 1: public override bool AuthorizeHubMethodInvocation(IHubIncomingInvokerContext hubIncomingInvokerContext, bool appliesToMethod) 2: { 3: var connectionId = hubIncomingInvokerContext.Hub.Context.ConnectionId; 4: // check the authenticated user principal from environment 5: var environment = hubIncomingInvokerContext.Hub.Context.Request.Environment; 6: var principal = environment["server.User"] as ClaimsPrincipal; 7: if (principal != null && principal.Identity != null && principal.Identity.IsAuthenticated) 8: { 9: // create a new HubCallerContext instance with the principal generated from token 10: // and replace the current context so that in hubs we can retrieve current user identity 11: hubIncomingInvokerContext.Hub.Context = new HubCallerContext(new ServerRequest(environment), connectionId); 12: return true; 13: } 14: else 15: { 16: return false; 17: } 18: } Since I had passed the user principal into request environment in previous method, I can simply check if it exists and valid. If so, what I need is to pass the principal into context so that SignalR hub can use. Since the "User" property is all read-only in "hubIncomingInvokerContext", I have to create a new "ServerRequest" instance with principal assigned, and set to "hubIncomingInvokerContext.Hub.Context". After that, we can retrieve the principal in my Hubs through "Context.User" as below. 1: public class DefaultHub : Hub 2: { 3: public object Initialize(string host, string service, JObject payload) 4: { 5: var connectionId = Context.ConnectionId; 6: ... ... 7: var domain = string.Empty; 8: var identity = Context.User.Identity as ClaimsIdentity; 9: if (identity != null) 10: { 11: var claim = identity.FindFirst("Domain"); 12: if (claim != null) 13: { 14: domain = claim.Value; 15: } 16: } 17: ... ... 18: } 19: } Finally I just need to add my "QueryStringBearerAuthorizeAttribute" into the SignalR pipeline. 1: app.Map("/signalr", map => 2: { 3: // Setup the CORS middleware to run before SignalR. 4: // By default this will allow all origins. You can 5: // configure the set of origins and/or http verbs by 6: // providing a cors options with a different policy. 7: map.UseCors(CorsOptions.AllowAll); 8: var hubConfiguration = new HubConfiguration 9: { 10: // You can enable JSONP by uncommenting line below. 11: // JSONP requests are insecure but some older browsers (and some 12: // versions of IE) require JSONP to work cross domain 13: // EnableJSONP = true 14: EnableJavaScriptProxies = false 15: }; 16: // Require authentication for all hubs 17: var authorizer = new QueryStringBearerAuthorizeAttribute(); 18: var module = new AuthorizeModule(authorizer, authorizer); 19: GlobalHost.HubPipeline.AddModule(module); 20: // Run the SignalR pipeline. We're not using MapSignalR 21: // since this branch already runs under the "/signalr" path. 22: map.RunSignalR(hubConfiguration); 23: }); On the client side should pass the Bearer token through query string before I started the connection as below. 1: self.connection = $.hubConnection(signalrEndpoint); 2: self.proxy = self.connection.createHubProxy(hubName); 3: self.proxy.on(notifyEventName, function (event, payload) { 4: options.handler(event, payload); 5: }); 6: // add the authentication token to query string 7: // we cannot use http headers since web socket protocol doesn't support 8: self.connection.qs = { Bearer: AuthService.getToken() }; 9: // connection to hub 10: self.connection.start(); Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• Configuring Fed Authentication Methods in OIF / IdP

  - by Damien Carru

  In this article, I will provide examples on how to configure OIF/IdP to map OAM Authentication Schemes to Federation Authentication Methods, based on the concepts introduced in my previous entry. I will show examples for the three protocols supported by OIF: SAML 2.0 SSO SAML 1.1 SSO OpenID 2.0 Enjoy the reading! Configuration As I mentioned in my previous article, mapping Federation Authentication Methods to OAM Authentication Schemes is protocol dependent, since the methods are defined in the various protocols (SAML 2.0, SAML 1.1, OpenID 2.0). As such, the WLST commands to set those mappings will involve: Either the SP Partner Profile and affect all Partners referencing that profile, which do not override the Federation Authentication Method to OAM Authentication Scheme mappings Or the SP Partner entry, which will only affect the SP Partner It is important to note that if an SP Partner is configured to define one or more Federation Authentication Method to OAM Authentication Scheme mappings, then all the mappings defined in the SP Partner Profile will be ignored. WLST Commands The two OIF WLST commands that can be used to define mapping Federation Authentication Methods to OAM Authentication Schemes are: addSPPartnerProfileAuthnMethod() to define a mapping on an SP Partner Profile, taking as parameters: The name of the SP Partner Profile The Federation Authentication Method The OAM Authentication Scheme name addSPPartnerAuthnMethod() to define a mapping on an SP Partner , taking as parameters: The name of the SP Partner The Federation Authentication Method The OAM Authentication Scheme name Note: I will discuss in a subsequent article the other parameters of those commands. In the next sections, I will show examples on how to use those methods: For SAML 2.0, I will configure the SP Partner Profile, that will apply all the mappings to SP Partners referencing this profile, unless they override mapping definition For SAML 1.1, I will configure the SP Partner. For OpenID 2.0, I will configure the SP/RP Partner SAML 2.0 Test Setup In this setup, OIF is acting as an IdP and is integrated with a remote SAML 2.0 SP partner identified by AcmeSP. In this test, I will perform Federation SSO with OIF/IdP configured to: Use LDAPScheme as the Authentication Scheme Use BasicScheme as the Authentication Scheme Map BasicSessionScheme  to  the urn:oasis:names:tc:SAML:2.0:ac:classes:Password Federation Authentication Method Use OAMLDAPPluginAuthnScheme as the Authentication Scheme Map OAMLDAPPluginAuthnScheme to  the urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport Federation Authentication Method LDAPScheme as Authentication Scheme Using the OOTB settings regarding user authentication in OAM, the user will be challenged via a FORM based login page based on the LDAPScheme. Also the default Federation Authentication Method mappings configuration maps only the urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport to LDAPScheme (also marked as the default scheme used for authentication), FAAuthScheme, BasicScheme and BasicFAScheme. After authentication via FORM, OIF/IdP would issue an Assertion similar to: <samlp:Response ...>    <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer>    <samlp:Status>        <samlp:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Success"/>    </samlp:Status>    <saml:Assertion ...>        <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer>        <dsig:Signature>            ...        </dsig:Signature>        <saml:Subject>            <saml:NameID ...>[email protected]</saml:NameID>            <saml:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:cm:bearer">                <saml:SubjectConfirmationData .../>            </saml:SubjectConfirmation>        </saml:Subject>        <saml:Conditions ...>            <saml:AudienceRestriction>                <saml:Audience>https://acme.com/sp</saml:Audience>            </saml:AudienceRestriction>        </saml:Conditions>        <saml:AuthnStatement AuthnInstant="2014-03-21T20:53:55Z" SessionIndex="id-6i-Dm0yB-HekG6cejktwcKIFMzYE8Yrmqwfd0azz" SessionNotOnOrAfter="2014-03-21T21:53:55Z">            <saml:AuthnContext>                <saml:AuthnContextClassRef>                   urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport                </saml:AuthnContextClassRef>            </saml:AuthnContext>        </saml:AuthnStatement>    </saml:Assertion></samlp:Response> BasicScheme as Authentication Scheme For this test, I will switch the default Authentication Scheme for the SP Partner Profile to BasicScheme instead of LDAPScheme. I will use the OIF WLST setSPPartnerProfileDefaultScheme() command and specify which scheme to be used as the default for the SP Partner Profile referenced by AcmeSP (which is saml20-sp-partner-profile in this case: getFedPartnerProfile("AcmeSP", "sp") ): Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the setSPPartnerProfileDefaultScheme() command:setSPPartnerProfileDefaultScheme("saml20-sp-partner-profile", "BasicScheme") Exit the WLST environment:exit() The user will now be challenged via HTTP Basic Authentication defined in the BasicScheme for AcmeSP. Also, as noted earlier, the default Federation Authentication Method mappings configuration maps only the urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport to LDAPScheme (also marked as the default scheme used for authentication), FAAuthScheme, BasicScheme and BasicFAScheme. After authentication via HTTP Basic Authentication, OIF/IdP would issue an Assertion similar to: <samlp:Response ...>    <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer>    <samlp:Status>        <samlp:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Success"/>    </samlp:Status>    <saml:Assertion ...>        <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer>        <dsig:Signature>            ...        </dsig:Signature>        <saml:Subject>            <saml:NameID ...>[email protected]</saml:NameID>            <saml:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:cm:bearer">                <saml:SubjectConfirmationData .../>            </saml:SubjectConfirmation>        </saml:Subject>        <saml:Conditions ...>            <saml:AudienceRestriction>                <saml:Audience>https://acme.com/sp</saml:Audience>            </saml:AudienceRestriction>        </saml:Conditions>        <saml:AuthnStatement AuthnInstant="2014-03-21T20:53:55Z" SessionIndex="id-6i-Dm0yB-HekG6cejktwcKIFMzYE8Yrmqwfd0azz" SessionNotOnOrAfter="2014-03-21T21:53:55Z">            <saml:AuthnContext>                <saml:AuthnContextClassRef>                   urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport                </saml:AuthnContextClassRef>            </saml:AuthnContext>        </saml:AuthnStatement>    </saml:Assertion></samlp:Response> Mapping BasicScheme To change the Federation Authentication Method mapping for the BasicScheme to urn:oasis:names:tc:SAML:2.0:ac:classes:Password instead of urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport for the saml20-sp-partner-profile SAML 2.0 SP Partner Profile (the profile to which my AcmeSP Partner is bound to), I will execute the addSPPartnerProfileAuthnMethod() method: Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the addSPPartnerProfileAuthnMethod() command:addSPPartnerProfileAuthnMethod("saml20-sp-partner-profile", "urn:oasis:names:tc:SAML:2.0:ac:classes:Password", "BasicScheme") Exit the WLST environment:exit() After authentication via HTTP Basic Authentication, OIF/IdP would now issue an Assertion similar to (see that the AuthnContextClassRef was changed from PasswordProtectedTransport to Password): <samlp:Response ...>    <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer>    <samlp:Status>        <samlp:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Success"/>    </samlp:Status>    <saml:Assertion ...>        <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer>        <dsig:Signature>            ...        </dsig:Signature>        <saml:Subject>            <saml:NameID ...>[email protected]</saml:NameID>            <saml:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:cm:bearer">                <saml:SubjectConfirmationData .../>            </saml:SubjectConfirmation>        </saml:Subject>        <saml:Conditions ...>            <saml:AudienceRestriction>                <saml:Audience>https://acme.com/sp</saml:Audience>            </saml:AudienceRestriction>        </saml:Conditions>        <saml:AuthnStatement AuthnInstant="2014-03-21T20:53:55Z" SessionIndex="id-6i-Dm0yB-HekG6cejktwcKIFMzYE8Yrmqwfd0azz" SessionNotOnOrAfter="2014-03-21T21:53:55Z">            <saml:AuthnContext>                <saml:AuthnContextClassRef>                   urn:oasis:names:tc:SAML:2.0:ac:classes:Password                </saml:AuthnContextClassRef>            </saml:AuthnContext>        </saml:AuthnStatement>    </saml:Assertion></samlp:Response> OAMLDAPPluginAuthnScheme as Authentication Scheme For this test, I will switch the default Authentication Scheme for the SP Partner Profile to OAMLDAPPluginAuthnScheme instead of BasicScheme.

Contrarily to LDAPScheme and BasicScheme, the OAMLDAPPluginAuthnScheme is not mapped by default to any Federation Authentication Methods. As such, OIF/IdP will not be able to find a Federation Authentication Method and will set the method in the SAML Assertion to the OAM Authentication Scheme name.

The WLST command will take a list of policies, delimited by the ',' character, instead of SAML 2.0 or SAML 1.1 where a single Federation Authentication Method had to be specified.

• In C++, I want to implement a ring iterator for a deque that contains a personally defined class.

  - by George

  I have a function of a "Table" class that should add a player to the table. I decided that if the seat is taken, the function should try and go through all the seats and add the player to the next available seat. How do I implement this in my addPlayer function? int Table::addPlayer(Player player, int position) { deque<Player>::iterator it; if(playerList[position] != "(empty seat)") { //What goes here? } playerList.put(player,it); cout >> "Player " >> player.toString >> " sits at position " >> position >> endl; }

• Setting up and using Bing Translate API Service for Machine Translation

  - by Rick Strahl

  Last week I spent quite a bit of time trying to set up the Bing Translate API service. I can honestly say this was one of the most screwed up developer experiences I've had in a long while - specifically related to the byzantine sign up process that Microsoft has in place. Not only is it nearly impossible to find decent documentation on the required signup process, some of the links in the docs are just plain wrong, and some of the account pages you need to access the actual account information once signed up are not linked anywhere from the administration UI. To make things even harder is the fact that the APIs changed a while back, with a completely new authentication scheme that's described and not directly linked documentation topic also made for a very frustrating search experience. It's a bummer that this is the case too, because the actual API itself is easy to use and works very well - fast and reasonably accurate (as accurate as you can expect machine translation to be). But the sign up process is a pain in the ass doubtlessly leaving many people giving up in frustration. In this post I'll try to hit all the points needed to set up to use the Bing Translate API in one place since such a document seems to be missing from Microsoft. Hopefully the API folks at Microsoft will get their shit together and actually provide this sort of info on their site… Signing Up The first step required is to create a Windows Azure MarketPlace account. Go to: https://datamarket.azure.com/ Sign in with your Windows Live Id If you don't have an account you will be taken to a registration page which you have to fill out. Follow the links and complete the registration. Once you're signed in you can start adding services. Click on the Data Link on the main page Select Microsoft Translator from the list This adds the Microsoft Bing Translator to your services. Pricing The page shows the pricing matrix and the free service which provides 2 megabytes for translations a month for free. Prices go up steeply from there. Pricing is determined by actual bytes of the result translations used. Max translations are 1000 characters so at minimum this means you get around 2000 translations a month for free. However most translations are probable much less so you can expect larger number of translations to go through. For testing or low volume translations this should be just fine. Once signed up there are no further instructions and you're left in limbo on the MS site. Register your Application Once you've created the Data association with Translator the next step is registering your application. To do this you need to access your developer account. Go to https://datamarket.azure.com/developer/applications/register Provide a ClientId, which is effectively the unique string identifier for your application (not your customer id!) Provide your name The client secret was auto-created and this becomes your 'password' For the redirect url provide any https url: https://microsoft.com works Give this application a description of your choice so you can identify it in the list of apps Now, once you've registered your application, keep track of the ClientId and ClientSecret - those are the two keys you need to authenticate before you can call the Translate API. Oddly the applications page is hidden from the Azure Portal UI. I couldn't find a direct link from anywhere on the site back to this page where I can examine my developer application keys. To find them you can go to: https://datamarket.azure.com/developer/applications You can come back here to look at your registered applications and pick up the ClientID and ClientSecret. Fun eh? But we're now ready to actually call the API and do some translating. Using the Bing Translate API The good news is that after this signup hell, using the API is pretty straightforward. To use the translation API you'll need to actually use two services: You need to call an authentication API service first, before you can call the actual translator API. These two APIs live on different domains, and the authentication API returns JSON data while the translator service returns XML. So much for consistency. Authentication The first step is authentication. The service uses oAuth authentication with a  bearer token that has to be passed to the translator API. The authentication call retrieves the oAuth token that you can then use with the translate API call. The bearer token has a short 10 minute life time, so while you can cache it for successive calls, the token can't be cached for long periods. This means for Web backend requests you typically will have to authenticate each time unless you build a more elaborate caching scheme that takes the timeout into account (perhaps using the ASP.NET Cache object). For low volume operations you can probably get away with simply calling the auth API for every translation you do. To call the Authentication API use code like this:/// /// Retrieves an oAuth authentication token to be used on the translate /// API request. The result string needs to be passed as a bearer token /// to the translate API. /// /// You can find client ID and Secret (or register a new one) at: /// https://datamarket.azure.com/developer/applications/ /// /// The client ID of your application /// The client secret or password /// public string GetBingAuthToken(string clientId = null, string clientSecret = null) { string authBaseUrl = https://datamarket.accesscontrol.windows.net/v2/OAuth2-13; if (string.IsNullOrEmpty(clientId) || string.IsNullOrEmpty(clientSecret)) { ErrorMessage = Resources.Resources.Client_Id_and_Client_Secret_must_be_provided; return null; } var postData = string.Format("grant_type=client_credentials&client_id={0}" + "&client_secret={1}" + "&scope=http://api.microsofttranslator.com", HttpUtility.UrlEncode(clientId), HttpUtility.UrlEncode(clientSecret)); // POST Auth data to the oauth API string res, token; try { var web = new WebClient(); web.Encoding = Encoding.UTF8; res = web.UploadString(authBaseUrl, postData); } catch (Exception ex) { ErrorMessage = ex.GetBaseException().Message; return null; } var ser = new JavaScriptSerializer(); var auth = ser.Deserialize<BingAuth>(res); if (auth == null) return null; token = auth.access_token; return token; } private class BingAuth { public string token_type { get; set; } public string access_token { get; set; } } This code basically takes the client id and secret and posts it at the oAuth endpoint which returns a JSON string. Here I use the JavaScript serializer to deserialize the JSON into a custom object I created just for deserialization. You can also use JSON.NET and dynamic deserialization if you are already using JSON.NET in your app in which case you don't need the extra type. In my library that houses this component I don't, so I just rely on the built in serializer. The auth method returns a long base64 encoded string which can be used as a bearer token in the translate API call. Translation Once you have the authentication token you can use it to pass to the translate API. The auth token is passed as an Authorization header and the value is prefixed with a 'Bearer ' prefix for the string. Here's what the simple Translate API call looks like:/// /// Uses the Bing API service to perform translation /// Bing can translate up to 1000 characters. /// /// Requires that you provide a CLientId and ClientSecret /// or set the configuration values for these two. /// /// More info on setup: /// http://www.west-wind.com/weblog/ /// /// Text to translate /// Two letter culture name /// Two letter culture name /// Pass an access token retrieved with GetBingAuthToken. /// If not passed the default keys from .config file are used if any /// public string TranslateBing(string text, string fromCulture, string toCulture, string accessToken = null) { string serviceUrl = "http://api.microsofttranslator.com/V2/Http.svc/Translate"; if (accessToken == null) { accessToken = GetBingAuthToken(); if (accessToken == null) return null; } string res; try { var web = new WebClient(); web.Headers.Add("Authorization", "Bearer " + accessToken); string ct = "text/plain"; string postData = string.Format("?text={0}&from={1}&to={2}&contentType={3}", HttpUtility.UrlEncode(text), fromCulture, toCulture, HttpUtility.UrlEncode(ct)); web.Encoding = Encoding.UTF8; res = web.DownloadString(serviceUrl + postData); } catch (Exception e) { ErrorMessage = e.GetBaseException().Message; return null; } // result is a single XML Element fragment var doc = new XmlDocument(); doc.LoadXml(res); return doc.DocumentElement.InnerText; } The first of this code deals with ensuring the auth token exists. You can either pass the token into the method manually or let the method automatically retrieve the auth code on its own. In my case I'm using this inside of a Web application and in that situation I simply need to re-authenticate every time as there's no convenient way to manage the lifetime of the auth cookie. The auth token is added as an Authorization HTTP header prefixed with 'Bearer ' and attached to the request. The text to translate, the from and to language codes and a result format are passed on the query string of this HTTP GET request against the Translate API. The translate API returns an XML string which contains a single element with the translated string. Using the Wrapper Methods It should be pretty obvious how to use these two methods but here are a couple of test methods that demonstrate the two usage scenarios:[TestMethod] public void TranslateBingWithAuthTest() { var translate = new TranslationServices(); string clientId = DbResourceConfiguration.Current.BingClientId; string clientSecret = DbResourceConfiguration.Current.BingClientSecret; string auth = translate.GetBingAuthToken(clientId, clientSecret); Assert.IsNotNull(auth); string text = translate.TranslateBing("Hello World we're back home!", "en", "de",auth); Assert.IsNotNull(text, translate.ErrorMessage); Console.WriteLine(text); } [TestMethod] public void TranslateBingIntegratedTest() { var translate = new TranslationServices(); string text = translate.TranslateBing("Hello World we're back home!","en","de"); Assert.IsNotNull(text, translate.ErrorMessage); Console.WriteLine(text); } Other API Methods The Translate API has a number of methods available and this one is the simplest one but probably also the most common one that translates a single string. You can find additional methods for this API here: http://msdn.microsoft.com/en-us/library/ff512419.aspx Soap and AJAX APIs are also available and documented on MSDN: http://msdn.microsoft.com/en-us/library/dd576287.aspx These links will be your starting points for calling other methods in this API. Dual Interface I've talked about my database driven localization provider here in the past, and it's for this tool that I added the Bing localization support. Basically I have a localization administration form that allows me to translate individual strings right out of the UI, using both Google and Bing APIs: As you can see in this example, the results from Google and Bing can vary quite a bit - in this case Google is stumped while Bing actually generated a valid translation. At other times it's the other way around - it's pretty useful to see multiple translations at the same time. Here I can choose from one of the values and driectly embed them into the translated text field. Lost in Translation There you have it. As I mentioned using the API once you have all the bureaucratic crap out of the way calling the APIs is fairly straight forward and reasonably fast, even if you have to call the Auth API for every call. Hopefully this post will help out a few of you trying to navigate the Microsoft bureaucracy, at least until next time Microsoft upends everything and introduces new ways to sign up again.

• Geohashing - recursively find neighbors of neighbors

  - by itsme

  I am now looking for an elegant algorithm to recursively find neighbors of neighbors with the geohashing algorithm (http://www.geohash.org). Basically take a central geohash, and then get the first 'ring' of same-size hashes around it (8 elements), then, in the next step, get the next ring around the first etc. etc. Have you heard of an elegant way to do so? Brute force could be to take each neighbor and get their neighbors simply ignoring the massive overlap. Neighbors around one central geohash has been solved many times (here e.g. in Ruby: http://github.com/masuidrive/pr_geohash/blob/master/lib/pr_geohash.rb) Edit for clarification: Current solution, with passing in a center key and a direction, like this (with corresponding lookup-tables): def adjacent(geohash, dir) base, lastChr = geohash[0..-2], geohash[-1,1] type = (geohash.length % 2)==1 ? :odd : :even if BORDERS[dir][type].include?(lastChr) base = adjacent(base, dir) end base + BASE32[NEIGHBORS[dir][type].index(lastChr),1] end (extract from Yuichiro MASUI's lib) I say this approach will get ugly soon, because directions gets ugly once we are in ring two or three. The algorithm would ideally simply take two parameters, the center area and the distance from 0 being the center geohash only (["u0m"] and 1 being the first ring made of 8 geohashes of the same size around it (= [["u0t", "u0w"], ["u0q", "u0n"], ["u0j", "u0h"], ["u0k", "u0s"]]). two being the second ring with 16 areas around the first ring etc. Do you see any way to deduce the 'rings' from the bits in an elegant way?

• A Quick HLSL Question (How to modify some HLSL code)

  - by electroflame

  Thanks for wanting to help! I'm trying to create a circular, repeating ring (that moves outward) on a texture. I've achieved this, to a degree, with the following code: float distance = length(inTex - in_ShipCenter); float time = in_Time; ///* Simple distance/time combination */ float2 colorIndex = float2(distance - time, .3); float4 shipColor = tex2D(BaseTexture, inTex); float4 ringColor = tex2D(ringTexture, colorIndex); float4 finalColor; finalColor.rgb = (shipColor.rgb) + (ringColor.rgb); finalColor.a = shipColor.a; // Use the base texture's alpha (transparency). return finalColor; This works, and works how I want it to. The ring moves outward from the center of the texture at a steady rate, and is constrained to the edges of the base texture (i.e. it won't continue past an edge). However, there are a few issues with it that I would like some help on, though. They are: By combining the color additively (when I set finalColor.rgb), it makes the resulting ring color much lighter than I want (which, is pretty much the definition of additive blending, but I don't really want additive blending in this case). I would really like to be able to pass in the color that I want the ring to be. Currently, I have to pass in a texture that contains the color of the ring, but I think that doing it that way is kind of wasteful and overly-cumbersome. I know that I'm probably being an idiot over this, so I greatly appreciate the help. Some other (possibly relevant) information: I'm using XNA. I'm applying this by providing it to a SpriteBatch (as an Effect). The SpriteBatch is using BlendState.NonPremultiplied. Thanks in advance! EDIT: Thanks for the answers thus far, as they've helped me get a better grasp of the color issue. However, I'm still unsure of how to pass a color in and not use a texture. i.e. Can I create a tex2D by using a float4 instead of a texture? Or can I make a texture from a float4 and pass the texture in to the tex2D? DOUBLE EDIT: Here's some example pictures: With the effect off: With the effect on: With the effect on, but with the color weighting set to full: As you can see, the color weighting makes the base texture completely black (The background is black, so it looks transparent). You can also see the red it's supposed to be, and then the white-ish it really is when blended additively.

• See the Lord of the Rings Epic from the Perspective of Mordor [eBook]

  - by ETC

  Much like the wildly popular book “Wicked” mixed up the good/bad dichotomy in the Wizard of Oz, “The Last Ring-Bearer” shows us the Mordor’s take on the Lord of the Rings. The work of a Russian paleontologist, Kirill Yeskov, “The Last Ring-Bearer” frames the conflict in the Lord of the Rings from the perspective of the citizens of Mordor. Salon magazine offers this summary, as part of their larger review: In Yeskov’s retelling, the wizard Gandalf is a war-monger intent on crushing the scientific and technological initiative of Mordor and its southern allies because science “destroys the harmony of the world and dries up the souls of men!” He’s in cahoots with the elves, who aim to become “masters of the world,” and turn Middle-earth into a “bad copy” of their magical homeland across the sea. Barad-dur, also known as the Dark Tower and Sauron’s citadel, is, by contrast, described as “that amazing city of alchemists and poets, mechanics and astronomers, philosophers and physicians, the heart of the only civilization in Middle-earth to bet on rational knowledge and bravely pitch its barely adolescent technology against ancient magic.” Hit up the link below to grab a PDF of the official English translation of Yeskov’s work.

• emacs -- keybind questions

  - by user565739

  I have successfully used Ctrl+Shift+Up ' Ctrl+Shift+down ' Ctrl+Shift+left' Ctrl+Shift+Right to different commands. But when I tried to use Ctrl+s to the command save-buffer and Ctrl+Shift+s, which is equivalent to Ctrl+S, to another command, it has some problem. save-buffer works fine, but when I type Ctrl+Shift+s, it excute the command save-buffer. I used Ctrl+q to find the control sequences of Ctrl+s and Ctrl+Shift+S, I get the same result, which is ^S. I expect that I will get ^s for Ctrl+s, but it doesn't. Anyone knows the reason? Another queston is: I use Ctrl+c for the command killing-ring-save. In this case, all commands (which are of large number) begin with Ctrl+c don't work now. Is there a way to replace the prefix Ctrl+c by another customized prefix? I may pose my question in the wrong direction. I use ctrl+c as killing-ring-save. It works fine in emacs (no mode). But if I open a .c file (C-mode), then when I type Ctrl+c, it waits me to type another key. I think in this case, ctrl+c is regarded as a prefix. In this case, I need the following modifications: Using a custom defined prefix, say Ctrl+a, as Ctrl+c ; Remove the prefix Ctrl+c ; Using Ctrl+c as killing-ring-save. I add the following to my ~/.emacs : (defun my-c-initialization-hook () (define-key c-mode-base-map (kbd "C-a") mode-specific-map) (define-key c-mode-base-map (kbd "C-c") 'kill-ring-save)) (add-hook 'c-initialization-hook 'my-c-initialization-hook) But this doesn't work. Ctrl+c is still regarded as a prefix, so I can't use it as kill-ring-save. Furthermore, if I type Ctrl+a Ctrl+c, it said it's not defined. (I thought it will have the same result as I type Ctrl+c Ctrl+c)

• Combine 3D objects in XNA 4

  - by Christoph

  Currently I am writing on my thesis for university, the theme I am working on is 3D Visualization of hierarchical structures using cone trees. I want to do is to draw a cone and arrange a number of spheres at the bottom of the cone. The spheres should be arranged according to the radius and the number of spheres correctly. As you can imagine I need a lot of these cone/sphere combinations. First Attempt I was able to find some tutorials that helped with drawing cones and spheres. Cone public Cone(GraphicsDevice device, float height, int tessellation, string name, List<Sphere> children) { //prepare children and calculate the children spacing and radius of the cone if (children == null || children.Count == 0) { throw new ArgumentNullException("children"); } this.Height = height; this.Name = name; this.Children = children; //create the cone if (tessellation < 3) { throw new ArgumentOutOfRangeException("tessellation"); } //Create a ring of triangels around the outside of the cones bottom for (int i = 0; i < tessellation; i++) { Vector3 normal = this.GetCircleVector(i, tessellation); // add the vertices for the top of the cone base.AddVertex(Vector3.Up * height, normal); //add the bottom circle base.AddVertex(normal * this.radius + Vector3.Down * height, normal); //Add indices base.AddIndex(i * 2); base.AddIndex(i * 2 + 1); base.AddIndex((i * 2 + 2) % (tessellation * 2)); base.AddIndex(i * 2 + 1); base.AddIndex((i * 2 + 3) % (tessellation * 2)); base.AddIndex((i * 2 + 2) % (tessellation * 2)); } //create flate triangle to seal the bottom this.CreateCap(tessellation, height, this.Radius, Vector3.Down); base.InitializePrimitive(device); } Sphere public void Initialize(GraphicsDevice device, Vector3 qi) { int verticalSegments = this.Tesselation; int horizontalSegments = this.Tesselation * 2; //single vertex on the bottom base.AddVertex((qi * this.Radius) + this.lowering, Vector3.Down); for (int i = 0; i < verticalSegments; i++) { float latitude = ((i + 1) * MathHelper.Pi / verticalSegments) - MathHelper.PiOver2; float dy = (float)Math.Sin(latitude); float dxz = (float)Math.Cos(latitude); //Create a singe ring of latitudes for (int j = 0; j < horizontalSegments; j++) { float longitude = j * MathHelper.TwoPi / horizontalSegments; float dx = (float)Math.Cos(longitude) * dxz; float dz = (float)Math.Sin(longitude) * dxz; Vector3 normal = new Vector3(dx, dy, dz); base.AddVertex(normal * this.Radius, normal); } } // Finish with a single vertex at the top of the sphere. AddVertex((qi * this.Radius) + this.lowering, Vector3.Up); // Create a fan connecting the bottom vertex to the bottom latitude ring. for (int i = 0; i < horizontalSegments; i++) { AddIndex(0); AddIndex(1 + (i + 1) % horizontalSegments); AddIndex(1 + i); } // Fill the sphere body with triangles joining each pair of latitude rings. for (int i = 0; i < verticalSegments - 2; i++) { for (int j = 0; j < horizontalSegments; j++) { int nextI = i + 1; int nextJ = (j + 1) % horizontalSegments; base.AddIndex(1 + i * horizontalSegments + j); base.AddIndex(1 + i * horizontalSegments + nextJ); base.AddIndex(1 + nextI * horizontalSegments + j); base.AddIndex(1 + i * horizontalSegments + nextJ); base.AddIndex(1 + nextI * horizontalSegments + nextJ); base.AddIndex(1 + nextI * horizontalSegments + j); } } // Create a fan connecting the top vertex to the top latitude ring. for (int i = 0; i < horizontalSegments; i++) { base.AddIndex(CurrentVertex - 1); base.AddIndex(CurrentVertex - 2 - (i + 1) % horizontalSegments); base.AddIndex(CurrentVertex - 2 - i); } base.InitializePrimitive(device); } The tricky part now is to arrange the spheres at the bottom of the cone. I tried is to draw just the cone and then draw the spheres. I need a lot of these cones, so it would be pretty hard to calculate all the positions correctly. Second Attempt So the second try was to generate a object that builds all vertices of the cone and all of the spheres at once. So I was hoping to render a cone with all its spheres arranged correctly. After a short debug I found out that the cone is created and the first sphere, when it turn of the second sphere I am running into an OutOfBoundsException of ushort.MaxValue. Cone and Spheres public ConeWithSpheres(GraphicsDevice device, float height, float coneDiameter, float sphereDiameter, int coneTessellation, int sphereTessellation, int numberOfSpheres) { if (coneTessellation < 3) { throw new ArgumentException(string.Format("{0} is to small for the tessellation of the cone. The number must be greater or equal to 3", coneTessellation)); } if (sphereTessellation < 3) { throw new ArgumentException(string.Format("{0} is to small for the tessellation of the sphere. The number must be greater or equal to 3", sphereTessellation)); } //set properties this.Height = height; this.ConeDiameter = coneDiameter; this.SphereDiameter = sphereDiameter; this.NumberOfChildren = numberOfSpheres; //end set properties //generate the cone this.GenerateCone(device, coneTessellation); //generate the spheres //vector that defines the Y position of the sphere on the cones bottom Vector3 lowering = new Vector3(0, 0.888f, 0); this.GenerateSpheres(device, sphereTessellation, numberOfSpheres, lowering); } // ------ GENERATE CONE ------ private void GenerateCone(GraphicsDevice device, int coneTessellation) { int doubleTessellation = coneTessellation * 2; //Create a ring of triangels around the outside of the cones bottom for (int index = 0; index < coneTessellation; index++) { Vector3 normal = this.GetCircleVector(index, coneTessellation); //add the vertices for the top of the cone base.AddVertex(Vector3.Up * this.Height, normal); //add the bottom of the cone base.AddVertex(normal * this.ConeRadius + Vector3.Down * this.Height, normal); //add indices base.AddIndex(index * 2); base.AddIndex(index * 2 + 1); base.AddIndex((index * 2 + 2) % doubleTessellation); base.AddIndex(index * 2 + 1); base.AddIndex((index * 2 + 3) % doubleTessellation); base.AddIndex((index * 2 + 2) % doubleTessellation); } //create flate triangle to seal the bottom this.CreateCap(coneTessellation, this.Height, this.ConeRadius, Vector3.Down); base.InitializePrimitive(device); } // ------ GENERATE SPHERES ------ private void GenerateSpheres(GraphicsDevice device, int sphereTessellation, int numberOfSpheres, Vector3 lowering) { int verticalSegments = sphereTessellation; int horizontalSegments = sphereTessellation * 2; for (int childCount = 1; childCount < numberOfSpheres; childCount++) { //single vertex at the bottom of the sphere base.AddVertex((this.GetCircleVector(childCount, this.NumberOfChildren) * this.SphereRadius) + lowering, Vector3.Down); for (int verticalSegmentsCount = 0; verticalSegmentsCount < verticalSegments; verticalSegmentsCount++) { float latitude = ((verticalSegmentsCount + 1) * MathHelper.Pi / verticalSegments) - MathHelper.PiOver2; float dy = (float)Math.Sin(latitude); float dxz = (float)Math.Cos(latitude); //create a single ring of latitudes for (int horizontalSegmentsCount = 0; horizontalSegmentsCount < horizontalSegments; horizontalSegmentsCount++) { float longitude = horizontalSegmentsCount * MathHelper.TwoPi / horizontalSegments; float dx = (float)Math.Cos(longitude) * dxz; float dz = (float)Math.Sin(longitude) * dxz; Vector3 normal = new Vector3(dx, dy, dz); base.AddVertex((normal * this.SphereRadius) + lowering, normal); } } //finish with a single vertex at the top of the sphere base.AddVertex((this.GetCircleVector(childCount, this.NumberOfChildren) * this.SphereRadius) + lowering, Vector3.Up); //create a fan connecting the bottom vertex to the bottom latitude ring for (int i = 0; i < horizontalSegments; i++) { base.AddIndex(0); base.AddIndex(1 + (i + 1) % horizontalSegments); base.AddIndex(1 + i); } //Fill the sphere body with triangles joining each pair of latitude rings for (int i = 0; i < verticalSegments - 2; i++) { for (int j = 0; j < horizontalSegments; j++) { int nextI = i + 1; int nextJ = (j + 1) % horizontalSegments; base.AddIndex(1 + i * horizontalSegments + j); base.AddIndex(1 + i * horizontalSegments + nextJ); base.AddIndex(1 + nextI * horizontalSegments + j); base.AddIndex(1 + i * horizontalSegments + nextJ); base.AddIndex(1 + nextI * horizontalSegments + nextJ); base.AddIndex(1 + nextI * horizontalSegments + j); } } //create a fan connecting the top vertiex to the top latitude for (int i = 0; i < horizontalSegments; i++) { base.AddIndex(this.CurrentVertex - 1); base.AddIndex(this.CurrentVertex - 2 - (i + 1) % horizontalSegments); base.AddIndex(this.CurrentVertex - 2 - i); } base.InitializePrimitive(device); } } Any ideas how I could fix this?

• Is copy paste programming bad ?

  - by ring bearer

  With plain google as well as google code search tools it is easy to find how to program using some resource or solve certain problems ( such as a Java class, or a ftp block in perl etc) and so developers are so tempted to just purely copy paste the code (in a way re-use) - is this an incompetency? I have done this myself though I think I am a better programmer than many others I have seen. Who has the time to RTFM? In this age of information abundance, I do not think that copy paste programming is bad. Isn't that what sites like stackoverflow do anyway? People ask - ok here is my problem - how to solve it? now someone will post complete code and the person who asked the question would simply copy paste the most voted answer. No matter how small the problem is. I am working with a bunch of young coders who heavily rely on internet to get their job done. I see convenience (for example, you may be quite good with algorithms and such but you may not know how to use a BufferedReader in Java - would you read complete Javadoc for BufferedReader or look up some example of using it somewhere??) in copy pasting and modifying code to get the job done. What are the real dangers of copy paste coding that can impact their competency?
