• XML Architecture

  - by Roflcoptr

  For my application I have to use a undefined number of different detection strategies. A strategy is defined in the following fashion: The AND gate can also be a OR gate. For now, I hard coded all these rules in my code. For better extensability, I'd like to define all the detection startegies respectively rules in a XML file and parse it. But I'm not really sure how I can define such a detection strategy in a XML file. Any hints how to start?

• Flash music player stop working when I embed it into my index page

  - by janoChen

  Inside my /test folder/music_player/ have have a file called mini_player.swf. If I play it without embedding it anywhere, like this: http://ada.kiexpro.com/test/music_player/player_mini.swf everything is OK. But when I add it into my index page: http://ada.kiexpro.com/test/ the song doesn't start. I'm using a song_list.xml like this: <songs> <song> <track>She can dance too</track> <artist>Artist One</artist> <url>songs/song.mp3</url> </song> (continues)

• Passenger problem: "no such file to load" -- /config/environment

  - by Mason Jones

  I've been researching this one and found references to similar problems here and there, but none of them has led to a solution yet. I've installed passenger (2.2.11) and nginx (0.7.64) and when I start things up and hit a Rails URL, I get an error page informing me of a load error: no such file to load -- /path/to/app/config/environment From what I've found online this appears to be some sort of a user/permissions error, but I've tried all the logical fixes: I've made sure that /config/environment.rb is not owned by root, but by a webapp user. I've tried setting passenger_default_user, I've tried setting passenger_user_switching off. I've even tried setting the nginx user, though that shouldn't matter much. I've gotten some differing results, but nothing's actually worked. I'm hoping someone may have the magical combination of settings and permissions for this. I may try backing down to an earlier version of Passenger, because I've never had this issue before; it's been a little while since I set up Passenger though. Thanks for any suggestions.

• Startup params for Silverlight 4 app

  - by Number8

  Hello -- We are moving our SL3 app to SL4. First step was to open it in VS2010; it converted w/o problem. However, parameters specified for the start page are not passed along. That is, if we specify ourStartPage.aspx?Slam=Dunk&Glass=Sun in app.xaml.cs, Application_Startup(), e.InitParams is empty. How do we fix this? Thanks for any advice.... (Note that the very same startup string worked in VS2008.)

• Should I be worried about sending Apk to client before getting paid?

  - by DanielS

  I am working on an Android app for a client. The app is practically finished, and next week I'll have a meeting with the client to present it. He'll test everything, and upon approving it he will make the payment and I'll give him the source code and publish it on Google Play. Today he called me asking for the Apk so that he can start testing it. I am worried that if we don't close the deal (for one reason or another) he might get someone to reverse engineer the Apk and get my source code/app anyway, even if obfuscated with ProGuard (I never tried, but according to this SO thread it's not that difficult to reverse engineer an Apk). My question: Am I being paranoid here and should just send the client the Apk (cause perhaps the ProGuard obfuscation is enough to make the source code useless) , or are my worries reasonable and I should stick to getting paid before delivering anything?

• Pattern for iPhone background loading during init?

  - by Rob S.

  Hi everyone, I'm currently kicking off a background thread to do some REST queries in my app delegate's didFinishLaunchingWithOptions. This thread creates some objects and populates the model as the rest of the app continues to load (because I don't block, and didFinishLaunchingWithOptions returns YES). I also put up a loading UIViewController 'on top' of the main view that I tear down after the background initialization is complete. My problem is that I need to notify the first view (call it the Home view) that the model is ready, and that it should populate itself. The trick is that the background download could have finished before Home.viewDidAppear is called, or any of the other Home.initX methods. I'm having difficulty synchronizing all of this and I've thought about it long enough that it feels like I'm barking up the wrong tree. Are there any patterns here for this sort of thing? I'm sure other apps start by performing lengthy operations with loading screens :) Thanks!

• One configuration per domain name on the same application. How to easily access config values from m

  - by Aymeric

  Hi, I run a Ruby on Rails website that have multiple domain names. I have a "Website" table in the database that stores the configuration values related to each domain name: Website - domain - name - tagline - admin_email - etc... At the moment, I load the website object at the start of each request (before_filter) in my ApplicationController: @website = Website.find_by_domain(request.host) The problem is when I need to access the @website object from my models methods. I would like to avoid to have to pass @website everywhere. The best solution would be to have something similar to APP_CONFIG but per domain name. def sample_model_property - - "#{@website.name} is a great website!" end How would you do it?

• TypeError: Cannot find function 1.0.

  Hi, I have a script and I'm almost done but I get this error and frankly I have no idea what is wrong here. I'm rather new to Javascript so I suspect I did something wrong in the syntax somewhere. Here is an extract from the script containing the offending line : var gc = 0; var seg; var segCount = 0; var groupCount = 0; var groupLevel = 0; var segments = new Array(); var sk = ""; for(gc = 0; gc = groupDelimiters.length) break; if(seg.name() == groupDelimiters[gc]) { //ok we start another group grKeys.startNewGroup(groupLevel, groupCriterionExtractors[groupLevel](segCount), groupCount); groupLevel = gc + 1; //This line is flagged with the error in the title groupCount++; } } ideas, pointers, any help would be appreciated.

• Can't catch newConnection() signal from QTcpServer

  - by Bob

  I am trying to make a simple server thread in QT to accept a connection, however although the server is listening (I can connect with my test app) I can't get the newConnection() signal to be acted on. Any help as to what I'm missing here would be much appreciated! class CServerThread : public QThread { Q_OBJECT protected: void run(); private: QTcpServer* server; public slots: void AcceptConnection(); }; void CServerThread::run() { server = new QTcpServer; QObject::connect(server, SIGNAL(newConnection()), this, SLOT(AcceptConnection())); server-listen(QHostAddress::Any, 1000); // Any port in a storm exec(); // Start event loop } void CServerThread::AcceptConnection() { OutputDebugStringA("\n***** INCOMING CONNECTION"); // This is never called! }

• Tips about a good class-structure for website? (php)

  - by Martti Laine

  Hello I'm creating a kind of massive network for users to register and login. I want to try using classes, but I've never used them (expect some mysql-wrappers etc). Could you provide some tips and sample-structure for my project? The idea is to simply have a index.php, which prints the whole page and does all the action. Index.php calls functions from classes inside other files. I need: user-class for checking if logged in and retrieving user-info different kind of "page"-classes for functions needed in those pages I'm not asking for full code, but just a start. I don't know, how to use public functions or anything like that. How to wrap these classes to work together? So no functions, just the structure! Martti Laine

• Advise on starting a new job

  - by Sisiutl

  I hope this isn't too off-topic, but in a week I will start a new job at a manufacturing company managing the development of a new eCommerce site. The company scores about a 3 on the "Joel" test. I will inherit 3 programmers who developed the company web site and do general IT programming. I have the grey hair and credentials to have their initial respect but I'm an engineer, not a manager. I'm looking for practical advise - particularly for the first 90 days - on how to establish myself, keep the team together, and move forward.

• Jquery autosuggest google maps - Load on selection

  - by user1738522

  At the moment, the Google map code works like this: When you start typing in the input box it loads a list of suggestions. Then when you click on one of these options from the list, it puts it into the input box. However, THEN you still have to click find to load up the result. I want to have it so when you click on an option from the autosuggest list, it automatically loads the result, without having to click "find" afterwards. This is the code I am working with. I hope I explained this question correctly. http://jsfiddle.net/BxG9H/

• Reusing a vector in C++

  - by Bobby

  I have a vector declared as a global variable that I need to be able to reuse. For example, I am reading multiple files of data, parsing the data to create objects that are then stored in a vector. vector<Object> objVector(100); void main() { while(THERE_ARE_MORE_FILES_TO_READ) { // Pseudocode ReadFile(); ParseFileIntoVector(); ProcessObjectsInVector(); /* Here I want to 'reset' the vector to 100 empty objects again */ } } Can I reset the vector to be "vector objVector(100)" since it was initially allocated on the stack? If I do "objVector.clear()", it removes all 100 objects and I would have a vector with a size of 0. I need it to be a size of 100 at the start of every loop.

• How do I get the current Application Name (in terms of IIS) in a classic asp Web application

  - by Mr AH

  I have a classic asp application which retrieves the current application name and sets an Application variable containing that name. This name is important (I wont go into why) and is essentially the friendly name in IIS. The problem is, the implementation used to get this name is flawed, it a) assumes the home directory contains the string wwwroot, and b) assumes the folder name is the same as the application name. I can no longer guarantee these conditions. I would have thought the application name is know at run-time but I can't seem to find it in either Session or Application variables (at application start up entry point in global.asa). Any ideas?

• How to use Visual Studio and IIS7 together?

  - by Pure.Krome

  Hi folks, i'm trying to use Visual Studio 2010 (but this also happens with VS2008) as my web server for all locahost development. When i go into the properties for my web application (sigh, it's a legacy web FORMS app) and check the Web tab .. then check the Use Local IIS Web Server option ... it only allows me to create a virtual directory against a website. Why?! this is not what I want :( I wanted to have my own IIS7 website (no virtual directory) and debug against that. Can anyone help me? As a side note, i tried to use the third option Use Custom Web Server .. which ends up pointing to my localhost iis7 server. Now, this works ... but when i wish to Start Debugging .. it errors :( (it's not sure how to attach to that process or something?) So - can anyone out there please help?

• How should I think about perspectives and rotation in OpenGL ES?

  - by Omega

  As I start to write rendering code, how do I want to consider my drawing operations? Will they always be relative to a fixed coordinate system on the screen, or does this change based on the camera perspective? The best example I can try to come up with is say I'm at (0,0,0) and I draw a line to (3,3,3). If I change the perspective +1 on the X axis and conduct the same operation, does it happen at (4,3,3), or am I just getting a new view of the line still being made at (3,3,3)? When doing rotation, am I moving the point from which a frustum emanates, or am I moving the rendering underneath?

• threading.Event wait function not signaled when subclassing Process class

  - by user1313404

  For following code never gets past the wait function in run. I'm certain I'm doing something ridiculously stupid, but since I'm not smart enough to figure out what, I'm asking. Any help is appreciated. Here is the code: import threading import multiprocessing from multiprocessing import Process class SomeClass(Process): def __init__(self): Process.__init__(self) self.event = threading.Event() self.event.clear() def continueExec(self): print multiprocessing.current_process().name print self print "Set:" + str(self.event.is_set()) self.event.set() print "Set:" + str(self.event.is_set()) def run(self): print "I'm running with it" print multiprocessing.current_process().name self.event.wait() print "I'm further than I was" print multiprocessing.current_process().name self.event.clear() def main(): s_list = [] for t in range(3): s = SomeClass() print "s:" + str(s) s_list.append(s) s.start() raw_input("Press enter to send signal") for t in range(3): print "s_list["+str(t)+"]:" + str(s_list[t]) s_list[t].continueExec() raw_input("Press enter to send signal") for t in range(3): s_list[t].join() print "All Done" if __name__ == "__main__": main()

• How to evaluate "enterprise" platforms?

  - by Ran Biron

  Hi all, I'm tasked with evaluating an "enterprise" platform for the next-gen version of a product. We're currently considering two "types" of platforms - RAD (workflow engine, integrated UI, small cores of "technology plugins" to the workflows, automatic persisting of state...) like SalesForce.com / Service-Now.com and "cloud based" (EC2 / AppEngine...). While I have a few ideas on where to start, I'd like your opinions - how would you evaluate platforms for an enterprise suite of products? What factors would you consider? How would you eliminate weak options quickly enough to be able to concentrate on the few strong ones? Also interesting is how would you compare enterprise RAD (proven technology, quick to develop - but tends to look "the same as the competition") to cloud-based technology (lots of "buzz", not that many competitors - easy to justify to management, but probably lacking (?) enterprise tools and experience). As said before - I have a few ideas, but would like to see some answers before I post mine so I wouldn't drive the discussion to a specific place. RB.
