  • Is there a place where I see the popular opinion of developers?

    - by User1
    I really want to know popular opinion on controversial programming topics. Questions like: Why do some people prefer vi over emacs (or vice versa)? Is Java faster than C++? Is Intel faster than AMD? It seems SO discourages such conversions because of potential flamewars. So where do people go to discuss such matters? I'm especially interested in venues where people can "up vote" good comments and good questions.

    - by Fred
    Lets say you have decided to join company A. During interview you got feedback on what technology you would be working on(C# win app) and other details( sketchy).Now you have decided to join the company. Is it ok to ask via mail for further information and also ask to specify certain topics to brush up so that one can be better prepared for next job? Of course i know this question is not programming related.

  • What Design Pattern is this?

    - by 01
    I know that everything we do in programming can be described as design pattern(even abstract method has design pattern called template method) public class Guicer extends AbstractModule { private static Injector injector = Guice.createInjector(new Guicer()); public static void setInjector(Injector injector) { Guicer.injector = injector; } public static T getInstance(Class c) { return injector.getInstance(c); } @Override protected void configure() { } } What design patterns are used in this code?

  • How to disable listbox auto select item when pressing key

    - by tomfox66
    I have a listbox where I want to copy and paste items within that listbox. Copy and paste works fine but everytime I press "Crtl + C" the item starting with the letter C is automatically selected. Can this automatic selection be disabled or am I missing something here Here is the copy and paste method I implemented: private void listBox_Script_KeyDown(object sender, KeyEventArgs e) { if (e.Control == true && e.KeyCode == Keys.C) { int test = listBox_Script.SelectedIndex; Clipboard.SetDataObject(listBox_Script.Items[listBox_Script.SelectedIndex], true); return; } if (e.Control == true && e.KeyCode == Keys.V) { if (Clipboard.GetDataObject().GetDataPresent(DataFormats.Text)) { listBox_Script.Items.Insert(listBox_Script.SelectedIndex + 1, Clipboard.GetDataObject().GetData(DataFormats.Text).ToString()); return; } }

  • Which methods are good to overwrite when creating custom NSManagedObject subclasses?

    - by mystify
    The Core Data Programming Guide talks a lot about what not to overwrite. So the question is: What is good to overwrite? Like I see it, I can't overwrite -init or -initWithEntity:insertIntoManagedObjectContext: So where else would be a good overwrite point to set up some basic stuff? Or is it generally not needed to do custom initialization? Does the whole thing rely only on accessing properties which then start to do fancy things? So no custom initializations?

  • Cross vertion line matching.

    - by BCS
    I'm considering how to do automatic bug tracking and as part of that I'm wondering what is available to match source code line numbers (or more accurate numbers mapped from instruction pointers via something like addr2line) in one version of a program to the same line in another. (Assume everything is in some kind of source control and is available to my code) The simplest approach would be to use a diff tool/lib on the files and do some math on the line number spans, however this has some limitations: It doesn't handle cross file motion. It might not play well with lines that get changed It doesn't look at the information available in the intermediate versions. It provides no way to manually patch up lines when the diff tool gets things wrong. It's kinda clunky Before I start diving into developing something better: What already exists to do this? What features do similar system have that I've not thought of?

  • Switching to Java from C++: What are the key points?

    - by Roddy
    I'm an experienced developer, but most of my OO programming experience has been with C++ (and a little Delphi). I'm considering doing some Android work, hence Java. Coming from the C++ background, what areas of Java are most likely to surprise/annoy/delight me? I felt sure this would already have been asked, but my searches haven't turned up a similar question. CW, of course.

    - by Felipe
    Hi all. I have an application in asp.net mvc 2, and in this application, there are some parts that need to obey an configuration, for example. The app has an document management and the number of document (a field of my domain), need to be manual or automatic, and this choise will be consider in configuration. So, is there any pratice to do this? Need I render the number field (with hidden fields) in my View or it's not necessary? ViewData["key"] is recommended to make the form ? Thanks! Cheers

  • Are there any lightweight analogues to CORBA/RPC for embedded programs?

    - by Mtr
    I am writing embedded applications for different hardware (avr, arm7, tms55xx…) and different rtoses (freeRTOS, rtx, dsp/bios). And every second of them needs to communicate with PC or another digital device. Sometimes interactions logic is very advanced. So I'm interesting in common methodology (like state-machine programming style), protocol specification or library, that could simplify developing such things.

  • effective functonal sort

    - by sreservoir
    I'm programming a function for a ti-nspire, so I can't use the builtins from inside a function. what is the most generally efficient algorithm for sorting a list of numbers without modifying the list itself? (recursion and list-splitting are fair game, as is general use of math.)

  • python-like Java IO library?

    - by drozzy
    Java is not my main programming language so I might be asking the obvious. But is there a simple file-handling library in Java, like in python? For example I just want to say: File f = Open('file.txt', 'w') for(String line:f){ //do something with the line from file } Thanks!

  • What's the Erlang/Haskell job market like in the U.S.?

    - by Krystof
    I've heard that Telecoms are the big source of Erlang jobs but I'm not sure how much of a market there is. How likely is it that someone could find a job in Erlang/Haskell if they decided to learn it? In my case I have a lot of programming experience in Java but am tired of Java and want to try something different.

  • How to get a variable name as a string in Python?

    - by e-satis
    I would like to be able to get the name of a variable as a string but I don't know if Python has that much introspection capabilities. Something like: >>> print(my_var.__name__) 'my_var' I want to do that because I have a bunch of vars I'd like to turn into a dictionary like : bar=True foo=False >>> my_dict=dict(bar=bar, foo=foo) >>> print mydict >>> print my_dict {'foo': False, 'bar': True} But I'd like something more automatic than that. Python have locals() and vars(), so I guess there is a way.

  • C++ Libraries similar to C#?

    - by cam
    I'm coming to C++ from a .Net background. Knowing how to use the Standard C++ Libraries, and all the syntax, I've never ventured further. Now I'm looking learning a bit more, such as what libraries are commonly used? I want to start getting into Threading but have no idea to start. Is there a library (similar to how .net has System.Threading) out there that will make it a bit easier? I'm specifically looking to do Linux based network programming.

  • Data Structure Used For SMS Messages In Android

    - by Greenhouse Gases
    Does anybody know what data structures are used to the store messages in an SMS client app, and whether there is an existing API for this. I was perhaps looking at implementing a link list for the purpose but if the work has already been done in an API then perhaps it would be unnecessary to commit time to the task that could be spent programming other parts. Many thanks

  • Detecting inconsistent revisions of shared sources in SVN

    - by maxim1000
    I have an SVN repository containing several components: LibraryA LibraryB - depends on LibraryA Application - depends on LibraryB and LibraryA More detailed structure (branches and tags are not related to the problem): LibraryA LibraryA_code LibraryB LibraryB_code svn:externals to a fixed revision R1 of LibraryA_code Application Application_code svn:externals to a fixed revision R2 of LibraryA_code svn:externals to a fixed revision R3 of LibraryB_code The problem I'm trying to solve is automatic detection of situation when R2 differs from R1 (breaking expectations of LibraryB_code) and notification about this (e.g. build failure). I'll describe in an answer the only solution which I see for now, but I hope for something more elegant :) Environment: Windows, Visual Studio, SVN.

  • What is the 'accumulator in HQ9+?

    - by Koning Baard XIV
    I was just reading a bit about the HQ9+ programming language ( http://esolangs.org/wiki/HQ9 , http://en.wikipedia.org/wiki/HQ9%2B and http://www.cliff.biffle.org/esoterica/hq9plus.html ), and it tells me something about a so called 'accumulator' which can be incremented, but not be accessed. Also, using the + doesn't manipulate the result: code H+H result Hello World Hello World Can anyone explain me how this works, what this does and if it even makes any sense? Thanks
