• What components of your site do you typically "offload" or embed?

  - by Chad

  Here's what I mean. In developing my ASP.NET MVC based site, I've managed to offload a great deal of the static file hosting and even some of the "work". Like so: jQuery for my javascript framework. Instead of hosting it on my site, I use the Google CDN Google maps, obviously "offloaded" - no real work being performed on my server - Google hosted jQueryUI framework - Google CDN jQueryUI CSS framework - Google CDN jQueryUI CSS framework themes - Google CDN So what I'm asking is this, other than what I've got listed... What aspects of your sites have you been able to offload, or embed, from outside services? Couple others that come to mind... OpenAuth - take much of the authentication process work off your site Google Wave - when it comes out, take communication work off of your site

• What can cause throughput to become really slow when an ISAPI filter implements SF_NOTIFY_SEND_RAW_D

  - by Gerald

  I have an ISAPI filter for IIS6 that I've been developing for a while, but I just noticed something disturbing. Anytime I have the filter installed and I download a file, the file download becomes really slow. From a remote machine I'm getting ~120kb per second without the filter installed, and ~45kb per second with the filter installed. This seems to be related to the SF_NOTIFY_SEND_RAW_DATA callback. Whenever I register for this callback, I get the slow downloads, when I don't register for it, everything is fine. Even if I make my HttpFilterProc function just return immediately, like this: DWORD WINAPI HttpFilterProc( PHTTP_FILTER_CONTEXT pfc, DWORD notificationType, LPVOID pvNotification ) { return SF_STATUS_REQ_NEXT_NOTIFICATION; } I've also tried returning SF_STATUS_REQ_HANDLED_NOTIFICATION with the same result. Is it possible that I have some build setting on my DLL that is causing a slow execution of the callback function, or is this just the way it's going to be with ISAPI?

• Optional query string parameters in URITemplate in WCF?

  - by Shafique

  I'm developing some RESTful services in WCF 4.0. I've got a method as below: [OperationContract] [WebGet(UriTemplate = "Test?format=XML&records={records}", ResponseFormat=WebMessageFormat.Xml)] public string TestXml(string records) { return "Hello XML"; } So if i navigate my browser to http://localhost:8000/Service/Test?format=XML&records=10, then everything works as exepcted. HOWEVER, i want to be able to navigate to http://localhost:8000/Service/Test?format=XML and leave off the "&records=10" portion of the URL. But now, I get a service error since the URI doesn't match the expected URI template. So how do I implement defaults for some of my query string parameters? I want to default the "records" to 10 for instance if that part is left off the query string.

• It is possible to override a plugin's Controller from another plugin?

  - by fabschu

  I'm developing a plugin (MyPlugin) which combines some security functions to use it as a standard plugin for my next Grails application. It integrates the Spring-Security-Core and Spring-Security-UI plugins, and by its installation all dependencies should be installed automatically by adding the dependencies in the BuildConfig like: plugins { compile: ...} So far everything works fine, but in MyPlugin I'm changing the behaviour of the Spring-Security-UI plugin (password encoding in User Domain), by overwriting the UserController. Executing MyPlugin leads to the expected behaviour and new Users are created using the correct Controller. However, when installing MyPlugin in another Grails application, this behaviour fails and the original UserController of the Spring-Security-Ui plugin is used. I tried to solve this by configuring the dependsOn and loadAfter properties in the GrailsPlugin file, but without any success. Is it possible to fix this? Or is it only possible to overwrite behaviour/controllers in the main application?

• Logging strategy vs. performance

  - by vtortola

  Hi, I'm developing a web application that has to support lots of simultaneous requests, and I'd like to keep it fast enough. I have now to implement a logging strategy, I'm gonna use log4net, but ... what and how should I log? I mean: How logging impacts in performance? is it possible/recomendable logging using async calls? Is better use a text file or a database? Is it possible to do it conditional? for example, default log to the database, and if it fails, the switch to a text file. What about multithreading? should I care about synchronization when I use log4net? or it's thread safe out of the box? In the requirements appear that the application should cache a couple of things per request, and I'm afraid of the performance impact of that. Cheers.

• OpenGL Game development for the Desktop / Platform issues

  - by anon

  Does anyone have experience writing professional OpenGL games on Windows? For the Mac, due to apple's control, the OS seems quite "uniform". For windows, due to different hardware, different drivers installed, etc ... the hardware base seems to have many many different configurations. In theory, OpenGL provides a API that abstracts all this away. In practice, many drivers are often buggy and have weird cases -- has this been a problem for developing games on Windows? Thanks!

• Find coordinate by angle

  - by George Johnston

  I am developing in application in XNA which draws random paths. Unfortunately, I'm out of touch with graphing, so I'm a bit stuck. My application needs to do the following: Pick a random angle from my origin (0,0), which is simple. Draw a circle in relation to that origin, 16px away (or any distance I specify), at the angle found above. (Excuse my horrible photoshoping) The second circle at (16,16) would represent a 45 degree angle 16 pixels away from my origin. I would like to have a method in which I pass in my distance and angle that returns a point to graph at. i.e. private Point GetCoordinate(float angle, int distance) { // Do something. return new Point(x,y); } I know this is simple, but agian, I'm pretty out of touch with graphing. Any help? Thanks, George

• ASP.NET MVC 2 Dynamic QueryString Management

  - by vikas anand

  Hello All, I am very new to ASP.NET MVC and currently, I am involved in developing a new application in ASP.NET MVC 2. I am having problem in managing a long querystring parameters that comes from dBase. For example, in any non-mvc app the following URL works well: http ://example.com/test.aspx?first_name=fname&last_name=lname&email_id=email&address1=add1&address2=add2&city=city&state=state&zip_code=zip and so on. The QueryString parameter can be determined on the fly (i.e. at run-time). Now for dynamic QueryString how routing will be done? Also for a simple URL, the URL will be as follows (in ASP.NET MVC): http ://example.com/test/id/category But for above mentioned dynamic & long QueryString how the URL will look like? Will all the QueryString parameters be separated through slash (/)? Thanks in advance for your help. Best Regards, Vikas Anand

• URL on apache server does not default to the .php file after / has been added

  - by jeffkee

  Generally a url that looks like this: http://www.domain.com/product.php/12/ will open up product.php and serve the /12/ as request parameters, which then my PHP script can process to pull out the right product info. However when I migrated this whole site, after developing it, to a new server, I get a 404 error, because on that server it's not defaulting to the mother directory/file in case of an absence of requested directories. I vaguely remember learning that this is generally a common apache function but I can't seem to recall how to set it up or how to manipulate it.. if there's an .htaccess method to achieve this that would be great.

• Tibco Unit Testing tools

  - by mezoid

  Does anyone know what unit testing tools are available when developing Tibco processes? In the next few months I'll be working on a Tibco project and I'm trying to find any existing unit testing frameworks that might make the job easier to build with a TDD approach. Thus far, the only one I've been able to locate is called BWUnit. It seems ok but its currently in beta and its commercial software. If possible I'd like to use an open source tool but as long as it is able to do a good job I'd be happy. So does anyone know of any other unit testing tools for Tibco development?

• Is there any real benefit to using ASP.Net Authentication with ASP.Net MVC?

  - by alchemical

  I've been researching this intensely for the past few days. We're developing an ASP.Net MVC site that needs to support 100,000+ users. We'd like to keep it fast, scalable, and simple. We have our own SQL database tables for user and user_role, etc. We are not using server controls. Given that there are no server controls, and a custom membershipProvider would need to be created, where is there any benefit left to use ASP.Net Auth/Membership? The other alternative would seem to be to create custom code to drop a UniqueID CustomerID in a cookie and authenticate with that. Or, if we're paranoid about sniffers, we could encrypt the cookie as well. Is there any real benefit in this scenario (MVC and customer data is in our own tables) to using the ASP.Net auth/membership framework, or is the fully custom solution a viable route?

• Starting point for learning CAD/CAE file formats?

  - by Escader

  We are developing some stress and strain analysis software at university. Now it's time to move from rectangles and boxes and spheres to some real models. But I still have little idea where to start. In our software we are going to build mesh and then make calculations, but how do I import solid bodies from CAD/CAE software? 1) How CAD/CAE models are organised? How solid bodies are represented? What are the possibilities of DWG, DXF, IGES, STEP formats? There is e.g. a complete DXF reference, but it's too difficult for me to understand without knowing basic concepts. 2) Are there C++ libraries to import solid bodies from CAD/CAE file formats? Won't it be too difficult to build a complete model to be able to import comprehensive file?

• CCSprite following a sequence of CGPoints

  - by pgb

  I'm developing a line drawing game, similar to Flight Control, Harbor Master, and others in the appstore, using Cocos2D. For this game, I need a CCSprite to follow a line that the user has drawn. I'm storing a sequence of CGPoint structs in an NSArray, based on the points I get in the touchesBegin and touchesMoved messages. I now have the problem of how to make my sprite follow them. I have a tick method, that is called at the framerate speed. In that tick method, based on the speed and current position of the sprite, I need to calculate its next position. Is there any standard way to achieve this? My current approach is calculate the line between the last "reference point" and the next one, and calculate the next point in that line. The problem I have is when the sprite "turns" (moves from one segment of the line to another). Any hint will be greatly appreciated.

• EMail Signing (Outlook) Using Smartcard Minidriver [Windows]

  - by Baget

  Hi I'm developing a Smart card Minidriver and I'm trying to Sign an Email using Outlook 2007. I have implemented all of the necessary functions in the minidriver. I'm able to create a "Smartcard User" certificate and save it and it's private key on the smartcard (using Microsoft Certificate Services via the Minidriver). When I try to sign an EMail via Outlook I'm getting Error Message (Internal Error), the last call to the minidriver is for ReadFile with "cmapfile" When I try to sign an EMail via Outlook with a difference non-smartcard certificate it's work fine. When I try to sign a Data using CryptoAPI (based on Windows SDK Sample) it's working fine. I'm using Windows 7. someone got any idea how to debug this issue? I tried to enable the CAPI2 eventlog, it don't give me any good information.

  - by Julian

  Hi, I am developing a web application using asp.net mvc. I have come across the need to Temporarily create a class in the ascx/aspx file. This class will replace the Model during the development of the page. It will also hold some test data for the user to have the chance to see some results. Once we are happy with the layout on the screen, I will inherit the correct Model class through the Control tag. Can you please advise if this is possible and how to do it? This does not work: <% class Modelo { public Guid Guid { get; set; } public string Name { get; set; } } %> Thanks in advance, Be happy - Julian

• XML Signature in a Web application

  - by OpenDevSoft

  Hi, We are developing an e-Banking web application for a small bank (up to 20000 clients/users). We have to implement digital signatures with X509 certificates (issued by CA on USB tokens) for signing payment information. We tried using CAPICOM but it seems that it is not working well with Windows Vista (have not tried it with Win 7). The other problem is that core banking system can process only Xml digital signatures, so we have to sign XML documents (not just a bulk-formatted text data like with CAPICOM and Win32 Crypto API). So my questions here are: Does anyone of you have similar problem and how did they solved it? Is there a plug-in, library, component or external tool (for Internet Explorer and/or Fire Fox) that supports XML Digital Signatures in a web application? Can you please recommend some of these products and write something about your experience with them? Thank you very much.
