• What Read-eval-print-loops (REPL's) are available for C++ ?

  - by Justin Ethier

  REPL's are very useful for live debugging and experimentation. Most dynamic languages such as Ruby, Python, etc come with one built-in, however it is more difficult to build one for a statically-typed language such as C++. Despite the technical challenges, are there any REPL's available for C++?

• What are some affordable developer resources?

  - by ritu

  Hi Guys (and gals), In the past my employers bought me subscriptions to MSDN and Safari but now that I am working as a contractor and have to pay for these things myself, I was wondering if there are other services that offer subscriptions or access to technical books. I develop on Windows using C++ and .NET.

• gcc check if file is main (#if __BASE_FILE__ == __FILE__)

  - by Marcin Raczkowski

  Hello. In ruby there's very common idiom to check if current file is "main" file: if __FILE__ == $0 # do something here (usually run unit tests) end I'd like to do something similar in C after reading gcc documentation I've figured that it should work like this: #if __FILE__ == __BASE_FILE__ // Do stuff #endif the only problem is after I try this: $ gcc src/bitmap_index.c -std=c99 -lm && ./a.out src/bitmap_index.c:173:1: error: token ""src/bitmap_index.c"" is not valid in preprocessor expressions Am I using #if wrong?

• Does knowing a Natural Language well help with Programming?

  - by Earlz

  We all hear that math at least helps a little bit with programming. My question though, does English or other natural language skills help with programming? I know it has to help with technical documentation, but what about actual programming? Are certain constructs in a programming language also there in natural languages? Does knowing how to write a 20 page research paper help with writing a 20k loc programming project?

• Why do some APIs provide mostly interfaces, not classes?

  - by Lord Torgamus

  Some Java APIs provide a large number of interfaces and few classes. For example, the Stellent/Oracle UCM API is composed of roughly 80% interfaces/20% classes, and many of the classes are just exceptions. What is the technical reason for preferring interfaces to classes? Is it just an effort to minimize coupling? To improve encapsulation/information hiding? Something else?

• Why is J2EE scalable?

  - by py213py

  I heard from various sources that J2EE is highly scalable, but to me it seems that you could never scale a J2EE application to the level of the google search engine or any other large website. I would like to hear the technical reasons why it is so scalable.

• Specifics of List Membership

  - by phasetwenty

  How does Python (2.6.4, specifically) determine list membership in general? I've run some tests to see what it does: def main(): obj = fancy_obj(arg='C:\\') needle = (50, obj) haystack = [(50, fancy_obj(arg='C:\\')), (1, obj,), needle] print (1, fancy_obj(arg='C:\\'),) in haystack print needle in haystack if __name__ == '__main__': main() Which yields: False True This tells me that Python is probably checking the object references, which makes sense. Is there something more definitive I can look at?

• Way to generate a code that creates a constructor based on the current values of an object?

  - by burak ozdogan

  Hi, What I want to achieve is after loading my object from the database, to generate a code that will give me a block which initializes my object based on its current values so that I can use this code-block in my unit tests again and again without loading it from Db anymore. Is there any tool around to achieve such a goal for VS? thanks

• How to get Hudson to show complete selenium report?

• How do I connect StaticListableBeanFactory with ClassPathXmlApplicationContext?

  - by Aaron Digulla

  In the setup of my test cases, I have this code: ApplicationContext context = new ClassPathXmlApplicationContext( "spring/common.xml" ); StaticListableBeanFactory testBeanFactory = new StaticListableBeanFactory(); How do I connect the two in such a way that tests can register beans in the testBeanFactory during setup and the rest of the application uses them instead of the ones defined in common.xml? Note: I need to mix a static (common.xml) and a dynamic configuration. I can't use XML for the latter because that would mean to write 1000 XML files.

• Accessing smart card with Java

  - by Tom Brito

  I'm trying to learn about how does Java access smart cards, due to a project analysis. I wonder if there is any kind of virtual smart card which I could use to make some tests with Java? By the way, I've read about Java Card, and looks like it is used to run Java in cards, not to smart card data access, right?

• How can I find the dimensions of a matrix in Python?

  - by PBD10017

  How can I find the dimensions of a matrix in Python. Len(A) returns only one variable. Edit: Hi Thanks. close = dataobj.get_data(timestamps, symbols, closefield) Is (I assume) generating a matrix of integers (less likely strings). I need to find the size of that matrix, so I can run some tests without having to iterate through all of the elements. As far as the data type goes, I assume it's an array of arrays (or list of lists).
