• Consuming an iCal/.ics file in YQL

  - by Josh

  How would one consume an iCal/.ics file in YQL? Given an .ics such as: http://www.hebcal.com/export/ba/8a35a5efbb27548bc0272b94b8de96.ics?subscribe=1&v=1&year=2010&month=x&nh=on&tag=fp.ql&c=off How would I go about using YQL to select certain events based on fields, etc. I've tried the standard formats, and the only format that seems to even parse the file is HTML - which puts it all in a <p>, and removes the line returns that give the file meaning. I've had some success with using Yahoo Pipes' Fetch Feed Source, but was wondering if it's possible to do this entirely in YQL. Any ideas?

• How to create multiple SOAP webservice clients in same netbeans 6.8 project

  - by James Black

  I have a project that is largely just to help one application make connections to an SAP server, for real-time updates. So the first web service client works fine, but I try to create a second and it seems to hang and I expect part of the problem is that it is trying to create a new Service class, but the namespace for all the webservices are identical, but the wsdl is obviously different, so it can't create the client. I can do it manually, by just having Service1, Service2, etc, or making some other change, but the issue is that Netbeans should be able to do this easily. I can't use Eclipse as the wsimport parameters that Netbeans uses works, in Eclipse I would need to do too much to make it work, so I will go with the easier tool. I don't want to create a new project for each webservice, as that just seems to be perpetuating a design error. So, how can I easily create multiple webservice clients that will all have the same target namespace, using Netbeans 6.8+?

• How do I get the "Install Missing Plugin" yellow bar to appear in firefox when flash is not installe

  - by Janak

  My rails website uses the open_flash_graph plugin to generate flash graphs for my clients. If a customer doesn't have flash installed, it doesn't display any messages, it simply doesn't show any graphs. I've noticed that if I go to other websites that need flash, I get a yellow bar at the top of my firefox window that offers to "Install Missing Plugin". I assume something in the HTML lets firefox know that this webpage needs flash. What code do I need to add to my website to make this work?

• What is C's analogy to LabVIEW's Event Structure?

  - by SiegeX

  One programming construct I use quite a bit in LabVIEW is the Event Structure. This gives me the benefit of not having to needlessly waste CPU cycles via polling but only perform actions when an event I'm interested in is generated. As an experienced LabVIEW programmer with a decent understanding of C, I'm curious how one would go about emulating LabVIEW's event structure in C; preferably under Linux. A small code sample (like the one in the link above) illustrating how this might be done would be much appreciated. Also, if there already exists 3rd party libraries (for Linux) to add this event framework to C, that would be nice to know as well. Thanks.

• Selectively configuring Apache 2 mod_headers for Google Chrome Frame

  - by Adam Cobb

  I am currently evaluating Google Chrome Frame and so far i'm happy with it, but what i'd like to do is selectively use it for certain sections of my website. Some sections require ActiveX so need to be viewed in native IE, whereas others benefit greatly, and may end up requiring, Chrome Frame. I've currently got the following configured in my apache httpd.conf file - <IfModule mod_setenvif.c> <IfModule mod_headers.c> BrowserMatch chromeframe gcf Header append X-UA-Compatible "chrome=1" env=gcf </IfModule> </IfModule> This causes anything coming in via Apache to get the chrome frame stuff added to the headers. What I need is to make this only happen when a user visits particular URL's / particular pages, which i'm currently controlling via RewriteRules. Could anybody explain how I would go about this, as my understanding of the Apache config files isn't brilliant. Thanks.

• Best Data Structure For Time Series Data

  - by TriParkinson

  Hi all, I wonder if someone could take a minute out of their day to give their two cents on my problem. I would like some suggestions on what would be the best data structure for representing, on disk, a large data set of time series data. The main priority is speed of insertion, with other priorities in decreasing order; speed of retrieval, size on disk, size in memory, speed of removal. I have seen that B+ trees are often used in database because of their fast search times, but how about for fast insertion times? Is a linked list really the way to go? Thanks in advance for your time, Tri

• Is there a suggested solution structure for ASP.NET MVC Production Apps

  - by Eoin Campbell

  In general, I don't like to keep code (BaseClasses or DataAccess Code) in the App_Code directory of an ASP.NET Site. I'll usually pull this stuff out into a MySite.BusinessLogic & MySite.DataAccess DLL's respectively. I'm wondering should I be doing the same for ASP.NET MVC. Would it be better to Organise the solution something along the lines of MySite.Common - DLL - (Basic Functionality built on .NET System Dlls) MySite.DAL - DLL - (DataAccessLayer & DBML Files) MySite.Models - DLL - (MVC Models e.g. Repository Classes) MySite.Controllers - DLL (MVC Controllers which use Models) MySite - ASP.NET MVC Site. Or am I missing something... presumably, I'll lose some of the nice (Add View, Go To Controller, context menu items that have been added)

• Is there a way to export an XSD schema from a DataContract

  - by Eric

  I'm using DataContractSerializer to serialize/deserialize my classes to/from XML. Everything works fine, but at some point I'd like to establish a standard schema for the format of these XML files independent of the actual code. That way if something breaks in the serialization process I can always go back and check what the standard schema should be. Or if I do need to modify the schema the modification is an explicit decision rather then just a later affect of modifying my code. In addition, other people may be writing other software that may not be .NET based that would need to read from these XML files. I'd like to be able to provide them with some kind of documentation of the schema. Is there some relationship between a DataContract and an XSD schema. Is there a way to export the DataContract attributes in classes as an XSD schema?

• Why won't the VisualVM Profiler profile my application?

  - by Luke

  I've created a simple 1 file java application that iterates through a loop, calls some functions, allocates some memory, adds some numbers, etc. I run that application via eclipse's Run As->Java Application. The running application shows up in Java VisualVM under Local. I double click on that application and go to the Profiler tab. The default settings are: Start profiling from classes: my.main.package.** Do not profile classes: java.*, javax.*, sun.*, sunw.*, com.sun.* I click on CPU. The CPU and Memory buttons gray out. Nothing happens. The Status says profiling inactive. When my application terminates the Status says application terminated. What am I doing wrong here? Are there some settings I need to tweak? Do I need to set a VM flag when I launch my application?

• Undefined reference to cmph functions even after installing cpmh library

  - by user1242145

  I am using gcc 4.4.3 on ubuntu. I installed cmph library tools 0.9-1 using command sudo apt-get install libcmph-tools Now, when I tried to compile example program vector_adapter_ex1.c , gcc is able to detect cmph.h library in its include file but is showing multiple errors like vector_adapter_ex1.c:(.text+0x93): undefined reference to cmph_io_vector_adapter' vector_adapter_ex1.c:(.text+0xa3): undefined reference tocmph_config_new' vector_adapter_ex1.c:(.text+0xbb): undefined reference to cmph_config_set_algo' vector_adapter_ex1.c:(.text+0xcf): undefined reference tocmph_config_set_mphf_fd' even though, these are all defined in the source code of the cmph library. Could anyone tell the error that might have occurred or suggest an alternate method to go about building minimal perfect hash functions.

• Using ptrace to generate a stack dump

  - by Gomez

  Hello. I am compiling C++ on *nix and I would like to generate a stack dump a) at an arbitrary point in the program, b) during any signal, particularly during SIGSEGV. Google tells me that ptrace is probably the tool for the job, but I can't find any comprehensible examples of walking the stack. Getting the return address, yeah, but what about the NEXT return address? And what about extracting the symbolic name of the function at that point? Something to do with DWARF? Many thanks if you can tell me where to go from here.

• Some basic questions about Django, Pyjamas and Clean URLs

  - by Acidburn2k

  I am farily new to the topic, but I am trying to combine both Django and Pyjamas. What would be the smart way to combine the two? I am not asking about communication, but rather about the logical part. Should I just put all the Pyjamas generated JS in the base of the domain, say http://www.mysite.com/something and setup Django on a subdirectory, or even subdomain, so all the JSON calls will go for http://something.mysite.com/something ? As far as I understand now in such combination theres not much point to create views in Django? Is there some solution for clean urls in Pyjamas, or that should be solved on some oy,ther level? How? Is it a standard way to pass some arguments as GET parameteres in a clean url while calling a Pyjamas generated JS?

• UITableView programatically create delegate object?

  - by fuzzygoat

  I have a question regarding setting up a custom delegate class for use with UITableView. What I have done is as follows: Setup a new class (in sperate *.h and *.m files for the class) Conformed that new class to the <UITableViewDelegate, UITableViewDataSource> protocols Added the required methods. Created a pointer to the new object using @property and IBOutlet. In InterfaceBuilder created and assigned an object template to my new class Assigned the dataSource and delegate connections. This all works fine. My question is if I don't want to use interfaceBuilder to setup and instantiate my new delegate class directly in Xcode how do I go about doing that? More specifically how would I: Instantiate the delegate class, would that be created / owned by the controller? Set the dataSource and delegate connections? What is the best way of doing this? any help / information is much appreciated. Gary

• Silverlight WCF service acting strange

  - by Caleb Sandfort

  Hi I have a silverlight project that calls into a wcf service. Everything works fine on my local machine. However when I deploy to a virtual machine, with the exact same query the wcf service returns, but the result is empty. I've tried debugging, but have not been able to get it to break in the wcf service. Any ideas what the problem could be, or how I could go about debugging it? Thanks I figured out what the problem is, but am not sure what the solution is. In my silverlight project the wcf service I am referencing is http://localhost/.../SilverlightApiService.svc I used fiddler on my vm to see the request that was made and instead of trying to contact the above service, it was trying to contact: http:///.../SilverlightApiService.svc So, for some reason my machine name is getting inserted in there instead of localhost. Any thoughts on this would be appreciated.

• ASP.NET MVC <OutputCache> SqlDependency (CommandNotification?) with LINQ queries

  - by sinni800

  Hello, I use LINQ queries in my ASP.NET MVC application and want to use OutputCache in some of my Actions. I hear this should be possible with CommandNotifications. But those seem to only go for self-created SQLCommands, or am I wrong? Can I manually tell SQL server to send SQLDependency notifications if certain tables change? And if yes, how can I attach them to the OutputCache? Another side question: Can you do this with strongly types views too? Thank you in advance...

• Stack Overflow-like tag selector for Rails

  - by David Tildon

  I want to use tags for a model in my Rails application, and I'd like to have the same kind of tag selection mechanism that Stack Overflow has when asking a question. I.e. I type in 'rails' and it drops down a list of tags that include 'rails', and I can go on to add more tags from there. Is there a plugin that can do this? I'm comfortable putting together the tag model and migrations myself, that isn't an issue. I just need something to handle the AJAX and javascript. I'm using prototype and Rails 2.3.

• PLT Scheme URL dispatch

  - by Inaimathi

  I'm trying to hook up URL dispatch with PLT Scheme. I've taken a look at the tutorial and the server documentation. I can figure out how to route requests to the same servlets. Specific example: (define (start request) (blog-dispatch request)) (define-values (blog-dispatch blog-url) (dispatch-rules (("") list-posts) (("posts" (string-arg)) review-post) (("archive" (integer-arg) (integer-arg)) review-archive) (else list-posts))) (define (list-posts req) `(list-posts)) (define (review-post req p) `(review-post ,p)) (define (review-archive req y m) `(review-archive ,y ,m)) Assuming the above code running on a server listening 8080, localhost:8080/ goes to a page that says "list-posts". Going to localhost:8080/posts/test goes to a PLT "file not found" page (with the above code, I'd expect it to go to a page that says "review-post test"). It feels like I'm missing something small and obvious. Can anyone give me a hint?

• Basic Ruby on Rails Question about routing

  - by Acidburn2k

  I have a controller without any related model. This controller is to span some informations from various models. I have lots of actions there, which define certain views on the page. What would be the best way to organize routes for this controller. What I would like is to have /dashboard/something point to any action in the dashboard controller. Not actions like new/edit but arbitrary (showstats, etc). With trail and error I made something like this: map.dashboard 'dashboard/:action', :controller => 'dashboard', :action => :action Now it is possible to access those url using helper: dashboard_url('actionname') This approch seems to be working ok, but is this the way to go? I am not quite sure understand, how are the helper method names generated. How to generate same helper names as in basic controllers "action_controller_url" ? That would be more generic and made the code more consistent. Thanks in advance.
