• What Java/Scala or .NET web frameworks support modify source code and instantly run workflow e.i. wi

  - by Alexey

  As far as I can see the key advantage of dynamic languages like Ruby or Python over Java/Scala/C# etc is "hot" applying of your changes to source code to the running application. What are the frameworks for JVM or .NET that support the same workflow - apply changes to configuration and source code on the fly? Can they also watch changes to custom configurations and notify application? Note: Frameworks for dynamic languages on JVM/.NET like Grails or Compojure are out of scope here.

• How can I download YouTube videos using .NET code?

  - by JMSoft

  Does anybody know the VB or C# code to programmatically download a video from YouTube? I have gone through all related questions on this site and the only code I have found (which uses the WebClient Class webclient.DownloadFileAsync) returns the text source of the video, but not the Flash video (.flv) file that needs to be downloaded? Do you know any SDK or library which can help? I have also downloaded the GoogleAPI (YouTube DLL) but have not found a way of doing it.

• How would I implement code in a .h file into the main.cpp file?

  - by Lea

  I have a c++ project I am working on. I am a little stumped at the moment. I need a little help. I need to implement code from the .h file into the main.cpp file and I am not sure how to do that. For example code code from main.cpp: switch (choice){ case 1: // open an account { cout << "Please enter the opening balence: $ "; cin >> openBal; cout << endl; cout << "Please enter the account number: "; cin >> accountNum; cout << endl; break; } case 2:// check an account { cout << "Please enter the account number: "; cin >> accountNum; cout << endl; break; } and code from the .h file: void display(ostream& out) const; // displays every item in this list through out bool retrieve(elemType& item) const; // retrieves item from this list // returns true if item is present in this list and // element in this list is copied to item // false otherwise // transformers void insert(const elemType& item); // inserts item into this list // preconditions: list is not full and // item not present in this list // postcondition: item is in this list In the .h file you would need to use the void insert under transformer in the main.cpp under case 1. How would you do that? Any help is apprecaited. I hope I didn't confuse anyone on what I am needing to know how to do. Thanks

• Is a C++ compiler allowed to emit different machine code compiling the same program?

  - by sharptooth

  Consider a situation. We have some specific C++ compiler, a specific set of compiler settings and a specific C++ program. We compile that specific programs with that compiler and those settings two times, doing a "clean compile" each time. Should the machine code emitted be the same (I don't mean timestamps and other bells and whistles, I mean only real code that will be executed) or is it allowed to vary from one compilation to another?

• What is faster: write PHP code using "functions" or writing it as pure script?

  - by Ole Jak

  What is faster: writing PHP code using functions or writing it as pure script? So, as I see it Apache or any other server will create from PHP code using functions a pure script... I mean we had: function foo($a, $b){ return ($a + $b); echo foo(4, 5)} and Apache will turn it into something like: echo (5 + 4) Or will it?

• Tutorial how to create a CXF web service from existing Java code and embed it in Tomcat

  - by EugeneP

  Do you know a tutorial how to create a CXF web service from existing Java code and embed it in Tomcat, and also generate a wsdl file so that any .NET system would be able to generate client code easily? I miss that WSDL creation point in, for example this http://www.ibm.com/developerworks/library/ws-pojo-springcxf/ tutorial. No wsdl file is generated. But still it should be present in my case to provide system interoperability.

• Should you always write code for else cases that "can never happen"?

  - by johnswamps

  Take some code like if (person.IsMale()) { doGuyStuff(); } else { doGirlOtherStuff(); } (Yes, I realize this is bad OO code, it's an example) Should this be written so that to explicitly check if person.isFemale(), and then add a new else that throws an exception? Or maybe you're checking values in an enum, or something like that. You think that no one will add new elements to the enum, but who knows? "Can never happen" sounds like famous last words.

• What are the tell-tale signs that my code needs to make use of multi-threading?

  Hi, I am using a third party API which performs what I would assume are expensive operations in terms of time/resources used (image recognition, etc). What tell-tale signs are there that the code under test should be made to use threads to increase performance? I have a profiler and will be profiling the code I write which will rely on this API. Thanks
