• Current state of client-side XSLT

  - by Casey

  Last I heard, Blizzard was one of the few companies to put client-side XSLT into practice (2008). Is this still the case in 2011, or are more people now exploring this technique in production?  It seems that modern browsers (IE9, FF4, Chrome) and client processing power are primed to exploit this standard for tangible savings in server CPU power and bandwidth on large scale properties. Am I missing something? The negative aspects I'm aware of include * additional rendering time * additional assets required on uncached page load * additional layer of complexity * noticably less developer experience than server-side template techniques The benefits I perceive include * distributed template composition (offloaded on the client) * caching of common template fragments offloaded on the client * logical separation of document structure and data * well-documented web standard supported by all modern browsers Finally, although I know it's impossible to predict the future, I am curious to know opinions on whether or not client-side XSLT's day will come. With interest in HTML5 driving users to upgrade their browsers and developers to explore new techniques, I would say yes. How about you? Thanks in advance, Casey

• Calling Facebook API without authenticating user/"connecting"

  - by Andy

  Hi, I am working with facebook's API and I want to call the links.prevew method. http://wiki.developers.facebook.com/index.php/Links.preview Is it possible to call this method without having my user authenticate or "connect"? For example, not all of my users have hooked up their facebook accounts to my website, but I still want to use this API method. I am getting the following error: Fatal error: Uncaught Exception: 453: A session key is required for calling this method thrown in /public_html/libs/facebook.php on line 413 But on the wiki it says that the method does not require a session key? If it is not possible to make API calls without such a key, is there anyway I can make calls on behalf of my account or my applications account (rather then a users account)? Any help is appreciated, thanks!

• Browser for cross-site-script testing (for testing Mozilla Add-On)

  - by Anthony

  I am working on a Firefox extension that will involve ajax calls to domains that would normally fail due to the same-origin policy set by Firefox (and most modern browsers). I was wondering if there is a way to either turn off the same-origin restriction (in about:config, perhaps) or if there was a standard lite-browser that developers turn to for this. I really would like to avoid using any blackhat tools, if possible. Not because I'm against them, I just don't want to add another learning curve to the process. I can use curl in PHP to confirm that the requests work, but I want to get started on writing the js that the addon will actually use, so I need a client that will execute js. I also tried spidermonkey, but since I'm doing the ajax with jquery, it threw a fit at all of the browser-based default variables. So, short version: is there a reliable browser/client for cross site scripting that isn't primarily a hacker app? Or can I just turn off same-domain policy in Firefox?

• Running Stored Procedure with parameters resulting from query

  - by David in Dakota

  It's not hard to find developers who think cursors are gauche but I am wondering how to solve the following problem without one: Let's say I have a proc called uspStudentDelete that takes as a parameter @StudentID. uspStudentDelete applies a bunch of cascading soft delete logic, marking a flag on tables like "classes", "grades", and so on as inactive. uspStudentDelete is well vetted and has worked for some time. What would be the best way to run uspStudentDelete on the results of a query (e.g. select studentid from students where ... ) in *TSQL*?

• Does the android market use your merchant API callback URL during the Google checkout process for pa

  - by tootflow

  If I have a paid app on Android Market, will my merchant API callback URL get a hit when the customer goes to check out? I am wondering how merchants/vendors/developers secure their applications for android market. I have used google checkout before to implement a custom integration, so I understand how that all works. What I do not see anywhere that I have looked is what, if any, integration does the merchant/developer have with the Android Market checkout process? I understand that the market uses google checkout, but in that case the market hosts the checkout process and not the merchant, so it's not clear whether they give your URL a call. So where is the hook? Am I right in assuming it is the merchant API callback URL?

• Deploying Excel 2003 VSTO Workbook using Sharepoint for versioning control

  - by KClough

  I have an excel 2003 vsto workbook that I would like to make available via sharepoint for version control. Ideally it could be checked in/out by non-developers for tweaking excel equations, and I would be able to deploy the compiled dlls somewhere else when I need to update the managed VSTO code. I understand I may need to use some clickonce functionality as well so when a user first views the sheet they get all the necessary full-trust permissioning. Also, it is my understanding that for a user to use the vsto functionality in an excel 2003 vsto workbook, they must have the compiled dll in thier GAC, is this true? When testing I get trust exceptions otherwise.

• TFSBuild/MSBuild and Project Reference vs File Reference

  - by anon

  We Have a large VS solution using project references which is build by TFS Build like so: Solution - Project 1 - Project 2 - Project ... - Project N Because the solution is too large we have several smaller solutions which we use day to day: SubSolution - Project 1 - Project 19 The problem is that developers working on SubSolution find that it is not building because the project references could not be found, so they change the projects to use file references. This then goes on to break the TFS Build which cannot find these file references because they have not been built yet (Even though the projects are in the same solution). Is there a way around this tug of war between the two types of references. What is the correct way of splitting out your solutions?

• Setting Priorities on Bottons

  - by JONY

  Hello Android Developers, I am trying to figure out how to set priorities on imagebutton. I want to have a layout with a bunch of Icon or buttons that can be selected either by touch, radio, or checked box. As these images are selected they are set on queue to be displayed in order of Precedence. (that is to be pre-determined). The images are displayed once the main action button is touched. Any help will be greatly appreciated. Thank you,

• How to learn as a lone developer?

  - by fearofawhackplanet

  I've been lucky to work in a small team with a couple of experienced and knowledgeable developers for the first year of my career. I've learned a huge amount. But I'm now getting transferred within my company, and will be working on solo projects. I'll cope, but I know I'll make mistakes and won't always produce the best solutions without someone to guide me and review my output. I'm wondering if anyone has any tips in this situation. How can I keep learning? What's the best way to monitor and asses the quality of my work? How can I ensure that my career and skills don't stagnate?

• Have you been in cases where TDD increased development time?

  - by BillyONeal

  Hello everyone :) I was reading http://stackoverflow.com/questions/2512504/tdd-how-to-start-really-thinking-tdd and I noticed many of the answers indicate that tests + application should take less time than just writing the application. In my experience, this is not true. My problem though is that some 90% of the code I write has a TON of operating system calls. The time spent to actually mock these up takes much longer than just writing the code in the first place. Sometimes 4 or 5 times as long to write the test as to write the actual code. I'm curious if there are other developers in this kind of a scenario.

• Coordinating the logging output from a web app installed in a SharePoint farm.

  - by Kelly French

  We are deploying web parts to SharePoint 2007 and would like to include logging (log4net). The ideal solution would be to use a database appender to avoid the problems with knowing which actual server is executing the web part. This questions has been helpful: http://stackoverflow.com/questions/219668/sharepoint-and-log4net. I've got log4net working in a stand-alone web app using Visual Studio dev server using the web.config for the log4net settings and a file appender for the output. I'd like to transition to SharePoint and still use the log file output so I can make sure it's all working first, then change the config around to log to a database. Is this going to be too much trouble? How have other developers added log4.net into their solutions for SharePoint?

• Should economics be taught to geeks?

  - by asksuperuser

  When I interview developers for jobs I'm really astonished by their lack of economics consciousness. It seems they think they'll be recruited just for technological fun. When you ask them for technical solutions they would just follow hypes from software editors without consideration for the economics part. I have rejected 80% of candidates just for that kind of reason. I don't know if other recruiters ask economics questions, but as for me that is one of the main criterias. That is why I prefer to enquiry by myself on technical questions because I just don't trust the geeks choice. So did you learn economics at school ? At mine yes and that did serve me.

• If you can't do a Support Role, does this mean you should not be in development?

  - by Alex

  Hi, I've been shifted around roles a lot, and have been put in a support role which seems to deal out a lot of rubbish due to poor business management. Anyway, my line manager says that he's not sure he would recommend me for a developer role as they regard support as a poor technical role. What I resent is the fact that not all the information is available to us about what we're supporting and I miss coding. This thing I'm supporting has been regarded as a disaster when it went in and is still highly unstable. The thing is...does he have a point about Support roles being under developers, or are they completely two different kettle of fish?

• FBML in Rails views using Facebooker

  - by ewakened

  Hi all, I have successfully wired up a Facebook Connect application and everything is working fine. I can sign new users up with Facebook, or I can link existing users with Facebook. No problems there. However, now I am trying to add an Invite page, where a user can see which of their Friends have the application, and then show them a Facebook FMBL Multi Select form to invite friends into it. Here is the documentation for that FBML tag. http://wiki.developers.facebook.com/index.php/Connect/Integrating_an_Invite_Form_into_Your_Website#Creating_a_Full_Multi-friend_Selector_Request_or_Invite However, I cannot get this to work within my Rails view. Do I need to setup something special to use FBML in my Rails views? THIS IS NOT A CANVAS Application, meaning I want people to come to my site and not visit the page through facebook, but I feel like I am missing something. Thank you! Kent

• Help with game development. Render loop?

  - by John

  Hello, I'm working on a simple game, this is my first game project. Most of the samples I find have a Render Loop where all the game logic is made too and I just don't like this. Let's say I have a ball with X=0, and a wall in X=10 and in a slow machine, the first loop places the ball in X=7 and in a second loop, it places the ball in X=14. It would just crash the game! Is this "render loop" the right way to make games? Should I write code to check for things like this in every frame? Example, new frame X=14, last frame have X=7, so I should check if there's anything from X=7 to X=14?? I was thinking that I should have a separated thread for the game logic and in the render loop, I should just "take a snapshot" of the current game logic and display that, no? How do you guys, experienced game developers work around this? thanks!

• advice on working on remote asp.net applications

  - by Jonesy

  Hi folks, I'm a (relatively new) developer using asp.net with VB.NET. Currently all my applications are developed on my PC and then are built and moved onto the web server. I'm going to be working remotely for 3 months in which time I'll be connecting to the company network via VPN. What is the best way to access my projects? I need to have the projects stored on the company network so that others can access them too. So simply copying the projects to my laptop, working on them, then copying them back won't suffice. I tried to just open the projects off of the network share but am getting application trust problems. I'm just wondering what other developers do in this situation? Jonesy

• Variable as numeric sent to stored procedure (SQL Server 2005)

  - by TimCarrett

  I see that with SQL Server 2005 you can pass a parameter as numeric e.g. create procedure dbo.TestSP @Param1 numeric as But what does this equate to? E.g. Numeric(10,0), Numeric(9,2), etc? We have some Developers here who are using this instead of the correct definition for the field that this parameter is going to be used against e.g. instead of using Numeric(10, 0) for the parameter @Param1. Also are there any underlying performance issues with using Numeric instead of the data type defined against the field in the table? Many thanks.

• Metatool for automatic xml code generation

  - by iceman

  I want to develop a programming tool for developers which can do automatic xml code generation for specifying a GUI design and its controls. The aim is to allow non-programmers specify GUI controls(which in this case perform higher level task unlike WinForms ) from a GUI. So the xml code generated is essentially an internal representation which programmers can understand and further use in any automatic GUI generator. So the workflow is GUI(non-programmers)-xml(for programmers)-GUI(non-programmers). Is there a Microsoft project similar to this?

• added TextToSpeech to my activity and now my onDestroy is not called any more, bug?

  - by hermo

  I added TextToSpeech to my app, following the guidelines in the following post: http://android-developers.blogspot.com/2009/09/introduction-to-text-to-speech-in.html and now my onDestroy is no longer called when the back button is pressed. I filed a bug report regarding this: http://code.google.com/p/android/issues/detail?id=7674 Figured i should also ask here if someone else has seen this, and found a solution? It seems that it is the intent that causes the problem, i.e. the following: Intent checkIntent = new Intent(); checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA); startActivityForResult(checkIntent, MY_DATA_CHECK_CODE); If I skip this intent, and just go ahead and create a tts-instance, it works fine. Any clues to what is wrong with this intent?

• How do you authenticate user generated "apps" for your app?

  - by Brian Armstrong

  I'm think something like Facebook apps here. User generated pieces of code that people can write to interact with my app. I understand how an authenticated API works, but this seems a little more complicated because not only does the APP have to authenticate itself (with a regular api-key) but the USER using the app has to be authenticated somehow too, without giving the app free reign. I've been reading a bit here to see how FB does it: http://wiki.developers.facebook.com/index.php/How_Facebook_Authenticates_Your_Application And it looks like you have to pass a signature in addition to the api-key along with every call, but I'm having trouble wrapping my head around how this gets generated and used on the other end (my server). Figure there must be a simple explanation of this out there? Thanks! P.S. I'm building a Rails app if there are any applicable gems/plugins.

• Is there a nice XSL stylesheet for client-side DocBook rendering?

  - by Steven Huwig

  I want the DocBook documents in my SVN repository to look nice if someone looks at them in a web browser. I've started to write a CSS stylesheet, but I think that it will have significant limitations -- particularly ones regarding hyperlinks. There is a large body of DocBook XSL stylesheets at the DocBook site , but they don't seem to be appropriate for browser rendering. I don't want to generate static documents and put them into SVN. I want them to be basically readable for other developers without much hassle. I could write my own browser-appropriate XSL stylesheet to convert DocBook to HTML, but it seems like someone else must have already done this. I just don't know where to find it.

• Creating method templates in Eclipse

  - by stevebot

  Is there any way to do the following in eclipse? Have eclipse template a method like the following public void test(){ // CREATE MOCKS // CREATE EXPECTATIONS // REPLAY MOCKS // VERIFY MOCKS } so then I could presumably just use intellisense and select an option like "createtest" and have it stub out a method with the comments similar to the above?My problem is that often myself and other developers I know forgot all the steps we need to follow to do what we dub as a valid unit test for our application. If I could template our test methods to stub out the comments above it would be a big help.

• How can I create two contructors that act differently but recieve the same data type?

  - by Sergio Tapia

  public class Parser { Downloader download = new Downloader(); HtmlDocument Page; public Parser(string MovieTitle) { Page = download.FindMovie(MovieTitle); } public Parser(string ActorName) { Page = download.FindActor(ActorName); } } I want to create a constructor that will allow other developers who use this library to easily create a Parser object with the relevant HtmlDocument already loaded as soon as it's done creating it. The problem lies in that a constructor cannot exist twice with the same type of parameters. Sure I can tell the logical difference between the two paramters, but the computer can't. Any suggestions on how to handle this? Thank you!

• where do I submit the ipad apps?

  - by Mike

  I read Apple is allowing developers to submit iPad apps for the great opening of the ipad store, but I cannot find anything in my account that says that or allows sending the apps. Another thing is: in order for an app to be accepted you have to sign it with your own certificate but to do that you have to select the device on Xcode. As far as I know, Xcode do not signs with certificates applications that run on the simulator. Beyond that, any try to build a distribution package on Xcode shows messages like "you should disable armv6", and others. So, I ask. Is this news true? If yes, how to I manage to have the app ready for iPad and ready for submission? thanks.
