  • Centralized way of organizing urls in Jersey?

    - by drozzy
    Forgive me if I am asking an obvious question (maybe I missed it in the docs somewhere?) but has anyone found a good way to organize their URLs in Jersey Java framework? I mean organizing them centrally in your Java source code, so that you can be sure there are not two classes that refer to the same Url. For example django has a really nice regex-based matching. I was thinking of doing something like an enum: enum Urls{ CARS ("cars"), CAR_INFO ("car", "{info}"); public Urls(String path, String args) ... } but you can imagine that gets out of hand pretty quickly if you have urls like: cars/1/wheels/3 where you need multiple path-ids interleaved with one another... Any tips?

  • What is the result of "new int[ 0 ]"? [closed]

    - by ArunSaha
    Possible Duplicates: What does zero-sized array allocation do/mean? C++ new int[0] — will it allocate memory? int * p; p = new int[ 0 ]; What is the expected outcome when new is called for zero number of elements? Is the outcome defined or undefined? Further, is it okay to call delete [] p; on that pointer? What is the intuition/analogy to this situation of pointer to an array of zero elements? Thanks in advance. Regards, Arun

  • Understanding memory leak in Android app.

    - by sat
    After going through few articles about performance, Not able to get this statement exactly. "When a Drawable is attached to a view, the view is set as a callback on the drawable" Soln: "Setting the stored drawables’ callbacks to null when the activity is destroyed." What does that mean, e.g. In my app , I initialize an imageButton in onCreate() like this, imgButton= (ImageButton) findViewById(R.id.imagebtn); At later stage, I get an image from an url, get the stream and convert that to drawable, and set image btn like this, imgButton.setImageDrawable(drawable); According to the above statement, when I am exiting my app, say in onDestroy() I have to set stored drawables’ callbacks to null, not able to understand this part ! In this simple case what I have to set as null ? I am using Android 2.2 Froyo, whether this technique is required, or not necessary.

  • how good do you have to be to claim you have X amount of experience with X language/platform/skill

    - by dfafa
    sometimes i see job requirements saying you need 5 years of LAMP experience or resumes listing years of experience for each language.... what would you need to prove you have 5 years of experience at something ? i mean what if you rested for a while from coding ? what if you were actually "learning" during the first few years ? i feel no confidence at all and although i have been learning web programming (lamp) since 4 years ago, i am uncertain whether my skills qualify as to those of someone who has "5 years of LAMP" experience, and how would i be able to find out ? i've written several web apps....but they haven't taken off as i hoped.

  • Subfloat figures in latex

    - by jp88
    I am inputting a bunch of figures in Latex using \begin{figure}[h] \centering \subfloat etc. How do I get the subfloat figures to go to the next page? What I mean is, I'm inputting a ton of figures so it'll definitely be more than one page but if I do separate figures for each the a, b, c, d, etc. for the captions will change, so ideally I'd like one enormous figure with a bunch of subfloats a through z on different pages - how do you do that? Right now, I simply can't see the subfloat figures that stretch over the page, so I'll need to get another page somehow.

  • Twitter OAuth question

    - by Squall
    Hi there, I'm making a Twitter client in Java, and I've came to a problem I don't know how to solve it. How the hell I store open auth for twitter? I mean it doesn't make very sense for a person to allow an application every time he wants to use the client. I've been look at the Twitter documentation, but I must say, it's really poor in terms of Java. So do you guy have some idea to solve this? Thanks in advance!

  • How can I find out how much memory an object of a C++ class consumes?

    - by Shadow
    Hi, I am developing a Graph-class, based on boost-graph-library. A Graph-object contains a boost-graph, so to say an adjacency_list, and a map. When monitoring the total memory usage of my program, it consumes quite a lot (checked with pmap). Now, I would like to know, how much of the memory is exactly consumed by a filled object of this Graph-class? With filled I mean when the adjacency_list is full of vertices and edges. I found out, that using sizeof() doesn't bring me far. Using valgrind is also not an alternative as there is quite some memory allocation done previously and this makes the usage of valgrind impractical for this purpose. I'm also not interested in what other parts of the program cost in memory, I want to focus on one single object. Thank you.

  • Iphone UI Size / Layout Resource?

    - by blindJesse
    Is anyone aware of a website or download to reference for the size of UI elements or standard iphone interface stuff? What I mean is something that gives the height of elements like the status bar, tab bar, navigation bar, default tableviewcell height (and such things as width of accessory view, indentation, etc), default icon sizes, default font sizes for UI elements (if they need to be mimicked, for instance), etc etc etc. It's amazing how many times I have to go back to find a reference or estimate the size and position of a standard element. It seems like it would be an invaluable resource that could fit on a printed page or two.

  • Associate specific file extensions with my delphi app - any library for this?

    - by michal
    Hi, so far if I had to associate the file extension with my application I used to simply modify the registry. However I haven't been doing it for years, and I'm afraid the things might have changed a bit. I have no idea how to prevent registry access restrictions in Windows 7 / Vista (if there are any for HKEY_CLASSES_ROOT). Thus I'm looking for some delphi library, unit, code snippet or whatever which works reliably under XP, Vista and 7. Is there any which handles "backup" as well? By backup I mean possibility to revert the changes to the previous association ... Thanks in advance, m.

  • Erlang: simple refactoring

    - by alexey
    Consider the code: f(command1, UserId) -> case is_registered(UserId) of true -> %% do command1 ok; false -> not_registered end; f(command2, UserId) -> case is_registered(UserId) of true -> %% do command2 ok; false -> not_registered end. is_registered(UserId) -> %% some checks Now imagine that there are a lot of commands and they are all call is_registered at first. Is there any way to generalize this behavior (refactor this code)? I mean that it's not a good idea to place the same case in all the commands.

  • Help me to explain the F# Matrix transpose function

    - by Kev
    There is a Matrix transpose function: let rec transpose = function | (_::_)::_ as M -> List.map List.head M :: transpose (List.map List.tail M) | _ -> [] [[1; 2; 3]; [4; 5; 6]; [7; 8; 9]] |> transpose |> printfn "%A" It works fine. What does ( _ :: _ ) :: _ mean? I don't understand the whole code! Who can explain it? Thank You!

  • c++: truth assignment warning with arguments?

    - by John
    I use the following to work with arguments in my programs, but it seems to just hand me a warning (just a warning): "warning: suggest parentheses around assignment used as truth value" The beginning of the code is as follows: enum{OPT_DISP_H = 0x2, OPT_DISP_W = 0x1}; int main(int argc, char *argv[]) { int opt = 0x00; char c; while((++argv)[0] && argv[0][0]=='-'){ while(c =* ++argv[0]) switch(c){ case 'h': opt |= OPT_DISP_H; break; //etc.. The while(c =* ++argv[0]) part being where the warning persists. The code works fine, but what does this warning mean opposed to what is used? I think the code is c = *++argv[0], using the pointer. So why does the single = work and what is really recommended to be used?

  • how does [<Literal>] differ from other constants in F#

    - by Mitzh
    I am a bit confused by the Literal keyword and why it is necessary in F#. Reading the docs, it sounds to me that [<Literal>] is used to define a constant, however I am a bit confused how this constant differs from all other constants in F#.. Values that are intended to be constants can be marked with the Literal attribute. This attribute has the effect of causing a value to be compiled as a constant. When I think of a constant, I think of something which is immutable.... let x = "a" + "b" //this is a immutable value, its value is constant [<Literal>] let y = "a" + "b" //this is also a immutable value, but why is this a special constant? Is it because the 'normal' F# values are evaluated lazily and the [<Literal>] is not evaluated lazily..? is that what they mean with 'compiled as constant'..? or is there something else to it?

  • C++ Vector of pointers

    - by xbonez
    For my latest CS homework, I am required to create a class called Movie which holds title, director, year, rating, actors etc. Then, I am required to read a file which contains a list of this info and store it in a vector of pointers to Movies. I am not sure what the last line means. Does it mean, I read the file, create multiple Movie objects. Then make a vector of pointers where each element (pointer) points to one of those Movie objects? Do I just make two vectors - one of pointers and one of Movies and make a one-to-one mapping of the two vectors?

  • C (or C++?) Syntax: STRUCTTYPE varname = {0};

    - by Jared Updike
    Normally one would declare/allocate a struct on the stack with?: STRUCTTYPE varname; What does this syntax mean in C (or is this C++ only, or perhaps specific to VC++)? STRUCTTYPE varname = {0}; where STRUCTTYPE is the name of a stuct type, like RECT or something. This code compiles and it seems to just zero out all the bytes of the struct but I'd like to know for sure if anyone has a reference. Also, is there a name for this construct?

  • Trouble with SVN and Filename 'changes'.

    - by Stacey
    I am programming in Visual Studio 2010, using TortiseSVN and VisualSVN as my client to connect to SVN repositories. I am having a bit of a frequent problem though with the whole SVN thing in general. One thing that keeps cropping up is that if I make changes to files - namely filenames, or move them to new folders, etc, I end up getting all kinds of conflicts with the repository and it just causes all sorts of strange errors. I understand the importance of version control and check-in/check-out access like this, but what do most of you do to deal with this kind of thing? I mean, I've tried doing the whole 'Remove from Subversion', change my file, then 'Add to Subversion' thing, and it just doesn't seem to do the job very well. This is especially frustrating when working on web projects where filenames can change very frequently as a project evolves and becomes multifaceted. Are there any standard ways to deal with this kind of thing, or is it just one of the flaws of SVN in general?

    - by yokyo
    Hi, I'm pretty new to android, and just finished setup my environment and reading some tutorials. Then I got sdk samples from the web. Okay, what I wanna ask you is that is there a way to start a sample as a project in the Eclipse? I mean like clicking a project file in c# or a solution file. Here is my folder which I unzipped the code, \android-sdk-windows\samples\android-8\NotePad There are three folders and one file in the folder, \res, \src, \tests, and AndroidManifest.xml Or, do I need to make a new android project and import (or add files? maybe) them? Thanks in advance, yokyo

  • How can Domain driven design be combined with aspect oriented programming?

    - by anthares
    I'm doing research and one point I want to cover is "What is the relationship between Domain-driven Design and Aspect oriented programming?" I know that a main principle in DDD is separation of concerns and I understand that. What I'm not really certain is, whether aspects in AOP acts like "sub domains" in our domain in DDD. Are these two concepts, basically the same thing. I mean, If I develop an application following AOP and DDD, at the end of the day will it be true that "a sub domain" == "an aspect". I will also appreciate any other opinions what is the common between AOP and DDD.

  • Pass the current state of a function into another function in C/C++

    - by sand
    Is there a way to pass the current state of a function into another function in C/C++? I mean all the parameters and local variables by current state. For example: void funcA (int a, int b) { char c; int d, e; // Do something with the variables. // ... funcB(); // Do something more. } void funcB() { // funcB() should be able to access variables a,b,c,d & e // and any change in these variables reflect into funcA(). } The code is in bad shape if there is a need for funcB() kind of functions. But can it be achieved? This can help if someone is starting to re-factor a long method with multiple parameters.

  • Wrapping C/C++ inside Java

    - by Ashwin
    I develop applications/programs in C/C++. I am more versed in these two languages and love being a C++ developer. I am wondering how to create a Java program that contains all my C++ code. I mean, I would like to wrap all my C++ code (that is already developed) inside Java class. But clueless how to do it. Please post your responses or methods/steps on integrating C++ inside Java. (using JNI is the way, but I could not figure it out on www how to use it) FYI, I use Eclipse IDE to develop. How and what packages should I include in my project workspace?

  • php multidimensional array if loop

    - by user1091558
    I have a multidimensional array like this array[value][1][1] Now i would like to implement if loop like this if ($value = array[value][1][1]) { echo "It works"; } Now it works if i assign the values like [1][1],[2][1]. Is it possible to compare the whole array. I mean if the array looks like array[value][1][1],array[value][2][1],..........,array[value][n][1] It works should be echoed. I tried like this. if ($value = array[value][][]) { echo "It works"; } But its not working. Can anyone give me the correct syntax?

  • Web GUI frameworks for Phone development

    - by Runner
    I looked already and could't find anyting good. So a question is, are there any good web frameworks that would allow to easily develop GUI for the majority of high end phones? By this I mean It would have to work the same on majority of high end phones (forget the low cost ones) It would have to simplify the development and hide the ugly details from developer Clear design and good documentation. Also some stability on the market. The focus in on good looking and easy to make GUI. Javascript is only a plus. So basically I am looking for something like jQuery or maybe ExtJS for phone development. EDIT: It would be a big plus if it could be consumed in Delphi EDIT 2: If it was not clear, I am looking for a web base solution. So the target is HTML output and not native code.
