  • python streaming TCP server with RPC

    - by Noah
    I have written a little streaming mp3 server in python. So far all it does is accept a ServerSocket connection, and begin streaming all mp3 data in its queue to the request using socket.send(). I have implemented this to chunk in stream icy metadata, so the name of the playing song shows up in the client. I would like to add playlist management to the server, so that I can manipulate the playlist of the running server. I have a vague idea that xmlrpclib would be suited to doing this, but I'm confused about one thing: When I start the server it listens on port N. The python xmlrpclib examples involve creating a socket and listening for requests. So my question is should server listen on two ports; i.e., one for streaming client requests and one for xmlrpclib calls, or is there a way to do it by somehow delegating the request to the appropriate handler based on its type?

  • Consequences in PHP of implementing an interface through two different routes?

    - by Daniel Bingham
    What are the consequences of implementing the same interface through two different routes in PHP, are there any? What I mean, is something like this: interface baseInterface {} abstract class baseClass implements baseInterface { } interface myInterface extends baseInterface {} class myClass extends baseClass implements myInterface {} In this case myClass implements baseInterface from two different parents - myInterface and baseClass. Are there any consequences to this? My instinct is that PHP should handle this fine, but I just want to make sure. What exactly does PHP do in this case? Does it just check to see that the necessary functions are implemented for the interface each time it discovers it and call it a day or does it do something more?

  • Real life Java Swing Project

    - by santiagobasulto
    Hi everybody! I've been working with swing for the last 2 years, but i'm still not satisfy with my own work. The apps are "fast" enough, but the development isn't enough "clean". Can you recommend me any real world project, book, or something similar that shows me how a real world swing app work. May be a framework, something structured, etc. For example, i'm thinking i may code a "window manager" that has all the window of the app in an unified resource, may be cached, etc. I think all those good ideas must be implemented already. Thanks!

  • Reliably converting C preprocessor macros to python code

    - by manual-manuel
    Hi, I have a bunch of C macros the operation of which I need to simulate in python. I saw some pointers to pygccxml or ctypeslib etc. Are these the ways to go ? Or is there something out there that is better ? The C macros if and when they change, I would like the python implementation to be auto generated rather than having to make manual modifications. Hence the question. <my_c_header.h> /* #defines type 1 */ #ifdef OS #define NUM_FLAGS (uint16_t)(3) #define NUM_BITS (uint16_t)(8) #else #define NUM_FLAGS (uint16_t)(6) #define NUM_BITS (uint16_t)(16) #endif #define MAKE_SUB_FLAGS (uint16_t)((1<<NUMFLAGS) -1) #define MAKE_TOTAL_FLAGS(x) (uint16_t)((x & MAKE_SUB_FLAGS) >> NUM_BITS) /* #defines type 2 */ #ifdef OS #DO_SOMETHING(X) os_specifc_process(x) #else #DO_SOMETHING(x) #endif /* #defines type 3 */ enum { CASE0, CASE1, CASE2 } #define MY_CASE_0 ((uint16_t)CASE0) #define MY_CASE_1 ((uint16_t)CASE1) #define MY_CASE_2 ((uint16_t)CASE2) #define /*End of file <my_c_header.h> */ Thanks M

  • checkbox selected value is lost after coming back to the pagei.e., viewstate value is lost with use

    - by M.Vijay bhasker
    In the left navigation i have a series of check boxes and a grid view in the page body.Grid view results changes based on the check box selection,whenever i click on the links in grid view it goes to the second page and there is a link on the page which takes me back to the first page,but the check box selected value is maintained for the first time only and if we repeat the same process for the second time and i see that the first time selection of the check box is maintained.Here the grid view is placed in update panel and the check box in the left is called using .... AsyncPostBackTrigger ControlID="cphLeftNavigation". I've tried removing the above code referring the cphLeftNavigation and i see the results are coming up correctly and the last selected check box value is being maintained correctly and i want the same functionality to be implemented with/without update panel. Can anyone let me know,what exactly should i change to implement the above mentioned functionality.

  • Drag and drop objects onto a DIV.. relative vs absolute position and size of target DIV

    - by Scott
    Hi, I have a question about drag and drop and hoping one of you already solved it. I have an online web app where I can drag and drop annotations (arrows, stars) on top of an image that sits on a DIV. Here's some things to know. 1) The image can be any size (sometimes big sometimes small) 2) The DIV of wrapper can be left aligned or centered 3) The DIV of wrapper can be fixed or auto So is there any possible solution to make it so positions of annotations are always relative to the top left corner of the image? So I am using jQuery. How would I get an annotation's position always relative to the top left corner of an image once I drop object? Thanks!

  • EntityDataSource Unable to configure to Entity Model

    - by photo_tom
    I'm doing my first test asp.net3.5 app using EntityDataSource. I've got the basic project built and the Entity model created and compiled. Database is a local sqlexpress one in app_data directory. When I put the <asp:EntityDataSource /> control on the page and try to configure it, I'm getting the message "The list of named connections could not be loaded because the configuration could not be opened". At this point, everything in the project is "auto-created" by Visual Studio 2008sp1. I confused as I cannot find any information on how to correct from this message.

  • How to pass Remote Interface (aidl) throughout Activities ?

    - by Spredzy
    Hi All, I am developing an application using services and Remote interface. I have a question about passing the reference of my Remote interface throughout Activities. In my first Activity, I bind my service with my activity, in order to get a reference to my interface I use private ServiceConnection mConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName arg0, IBinder service) { x = X.Stub.asInterface(service); } @Override public void onServiceDisconnected(ComponentName arg0) { // TODO Auto-generated method stub } }; x being the reference to my interface. Now I would like to access this interface from another activity, I see two ways to do it but I don't know which one is the "proper" way to do it : passing x with my intent when I call the new Activity redo this.bindService(new Intent(y.this,z.class), mConnection, Context.BIND_AUTO_CREATE); in the onCreate() of my new Activity What would you advice me to do ?

  • Are C/C++/ObjC/JS Apple's only allowed langauges for iPhone development?

    - by fbrereto
    According to this post on Daring Fireball a new iPhone SDK Agreement release in conjunction with the iPhone OS 4.0 announcement today specifically bans any iPhone application not implemented in C, C++ Objective-C or JavaScript. The clear impact here is to the wide array of programs written in languages other than those. Is that your reading of the clause in the new agreement as well? Update: Here is the clause as printed on Daring Fireball: 3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited).

  • Persisting sensitve data in asp.net, odd implementation

    - by rawsonstreet
    For reasons not in scope of this question I have implemented a .net project in an iframe which runs from a classic asp page. The classic asp site persisted a few sensitive values by hitting the db on each page. I have passed there variables as xml to the aspx page, now I need to make these values available on any page of this .net site. I've looked into the cache object but we are on a web farm so I am not sure it would work. Is there a way I can can instantiate an object in a base page class and have other pages inherit from the base page to access these values? What is the best way to persist these values? A few more points to consider the site runs in https mode and I cannot use session variables, and I would like to avoid cookies if possible..

  • Customizing Bugzilla 4.0.2 Bug ID numbers

    - by Marcus Polk
    Is it possible to customize Bugzilla bug numbers and add a letter designator, to immediately know it came from Bugzilla? My company is evaluating Bugzilla and has now added many new bugs. We also use 2 other bug databases. This wasn't my decision and I believe they were trying to incorporate better reporting, etc. I read an answer here about "seeding" Bugzilla bug numbers, by setting the "AUTO_INCREMENT" field in the "bugs" table to a different value. I wish I would've thought about this sooner and found this board. Setting that value to start at 9000 or some extraordinary value would have ensured that we knew exactly which bugs came from Bugzilla. However, would it be possible to change the field in the "bugs" table to accept letters, as well? Of course that would probably just mess up the whole auto incrementing of the numbers. Any help or advice is greatly appreciated. Thank you.

  • WPF MVVM - Correct way to consume a web service asynchronously

    - by byte
    I have implemented MVVM in my WPF application. I was wondering what is the correct way to consume a Web Service from WPF MVVM app. So far, I have created a DataAccess interface and a class that implements this interface. This would serve as a facade / proxy to the web service. The ViewModel gets a reference to this class as the constructor parameter so it can make any calls to get/set data, in this case it will be a Web service call. I would appreciate if you can guide me with some hints and / or direct me to some online resource.

  • FTP/SFTP module for .NET

    - by Angrius
    I am designing an auto downloader using .NET and C#. I was wondering if there is a decent/robust FTP/SFTP module out there that I can use, preferably free of charge. EDIT: I probably should've noted that I am looking for answer from somebody who tried several and found one that works very well. I currently use .NET wrapper for libcurl for FTP and it does not behave right. For example when I connect to FTP site with Filezilla and provide a path, it finds directory just fine. With libcurl, i get a header for 404 page saying path cannot be found. I am guessing that Filezilla gets 'home' directory correctly, and libcurl puts me to the root (i tried no path, and i had no permissions to access that directory). But anyways, I just don't know enough about FTP itself, so I would like something that just works. Thanks!

  • Activate window/application

    - by LnDCobra
    I have implemented a Splash Screen according to WiredPrairie unmanaged c++ splasher class. But not when my application loads, my window isn't activated. The user has to click on the login box even thought it is the only window open in my application. I have tried the following but none of these work. Topmost = true; Focus(); Activate(); Is there any way to give my login window focus when the application starts? Sometimes the window behind it has focus! (Visual Studio if run on my machine), Explorer or a different application window on other peoples machines. Anyone have any idea?

  • Dynamic binding in C++

    - by chmike
    I'm implementing a CORBA like server. Each class has remotely callable methods and a dispatch method with two possible input, a string identifying the method or an integer which would be the index of the method in a table. A mapping of the string to the corresponding integer would be implemented by a map. The caller would send the string on the first call and get back the integer with the response so that it simply has to send the integer on subsequent calls. It is just a small optimization. The integer may be assigned dynamically on demand by the server object. The server class may be derived from another class with overridden virtual methods. What could be a simple and general way to define the method binding and the dispatch method ?

  • How do I release an object allocated in a different AutoReleasePool ?

    - by ajcaruana
    Hi, I have a problem with the memory management in Objective-C. Say I have a method that allocates an object and stores the reference to this object as a member of the class. If I run through the same function a second time, I need to release this first object before creating a new one to replace it. Supposing that the first line of the function is: NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; This means that a different auto-release pool will be in place. The code to allocate the object is as follows: if (m_object != nil) [m_object release]; m_object = [[MyClass alloc] init]; [m_object retain]; The problem is that the program crashes when running the last line of the method: [pool release]; What am I doing wrong ? How can I fix this ? Regards Alan

  • Will Algorithm written in OCaml compiled from C be Faster than Algorithm written in Pure C code?

    - by Ole Jak
    So I have some cool Image Processing algorithm. I have written it in OCaml. It performs well. I now I can compile it as C code with such command ocamlc -output-obj -o foo.c foo.ml (I have a situation where I am not alowed to use OCaml compiler to bild my programm for my arcetecture, I can use only specialy modified gcc. so I will compile that programm with sometyhing like gcc -L/usr/lib/ocaml foo.c -lcamlrun -lm -lncurses and Itll run on my archetecture.) I want to know in general case will my OCaml code compiled into C run faster than algorithm implemented in pure C?

  • Correct way to add objects to an ArrayList

    - by ninjasense
    I am trying to add an object to an arraylist but when I view the results of the array list, it keeps adding the same object over and over to the arraylist. I was wondering what the correct way to implement this would be. public static ArrayList<Person> parsePeople(String responseData) { ArrayList<Person> People = new ArrayList<Person>(); try { JSONArray jsonPeople = new JSONArray(responseData); if (!jsonPeople.isNull(0)) { for (int i = 0; i < jsonPeople.length(); i++) { Person.add(new Person(jsonPeople.getJSONObject(i))); } } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (Exception e) { } return People; } I have double checked my JSONArray data and made sure they are not duplicates. It seems to keep adding the first object over and over.

  • MassTransit Saga - Errors & Inconsistencies

    - by Tolu
    I've implemented a masstransit saga that works as should, a lot of times. However, there are times when the messages go to the error queue or just seem to disappear. I'd like to know: 1. How do I get the reason/exception message that causes a message to go to the error queue? (NOTE: My handler logic is within a try-catch block so apparently these errors happen even before the handler logic is called) 2. What could be responsible for the lost messages? Thanks in advance.
