  • Framework for Implementing REST web service in Django

    - by Laizer
    I'm looking to implement a RESTful interface for a Django application. It is primarily a data-service application - the interface will be (at this point) read-only. The question is which Django toolsets / frameworks make the most sense for this task. I see Django-rest and Django-piston. There's also the option of rolling my own. The question was asked here, but a good two years back. I'd like to know what the current state of play is. In this question, circa 2008, the strong majority vote was to not use any framework at all - just create Django views that reply with e.g. JSON. (The question was also addressed, crica 2008, here.) In the current landscape, what makes the most sense?

  • Add mask to input

    - by Lodewijk Wensveen
    I'm trying to achieve the seemingly impossible task of adding an mask to a input field. I have the following code: function addActivationCode(){ newRow = jQuery("div.activationcode:last-child").clone(); newRow.insertAfter(jQuery("div.activationcode:last-child")); newRow.attr("id", "coderow-" + Math.round(Math.random() * 10000)); newRow.find("input").val(""); find("input").mask("9999-9999-9999-9999"); newRow.find("a.coderemove").attr("onclick", "removeActivationCode('" + newRow.attr("id") + "'); return false;"); } function removeActivationCode(id){ jQuery("div#" + id).remove(); } Now I to get the .mask working on my input fields, so far I've only got it working on the new row I'm making and not on the original one. Can anyone help me out?

  • Java - SwingWorker - Can we call one SwingWorker from other SwingWorker instead of EDT

    - by Yatendra Goel
    I have a SwingWorker as follows: public class MainWorker extends SwingWorker(Void, MyObject) { : : } I invoked the above Swing Worker from EDT: MainWorker mainWorker = new MainWorker(); mainWorker.execute(); Now, the mainWorker creates 10 instances of a MyTask class so that each instance will run on its own thread so as to complete the work faster. But the problem is I want to update the gui from time to time while the tasks are running. I know that if the task was executed by the mainWorker itself, I could have used publish() and process() methods to update the gui. But as the tasks are executed by threads different from the Swingworker thread, how can I update the gui from intermediate results generated by threads executing tasks.

  • Python Least-Squares Natural Splines

    - by Eldila
    I am trying to find a numerical package which will fit a natural which minimizes weighted least squares. There is a package in scipy which does what I want for unnatural splines. import numpy as np import matplotlib.pyplot as plt from scipy import interpolate import random x = np.arange(0,5,1.0/2) xs = np.arange(0,5,1.0/500) y = np.sin(x+1) for i in range(len(y)): y[i] += .2*random.random() - .1 knots = np.array([1,2,3,4]) tck = interpolate.splrep(x,y,s=1,k=3,t=knots,task=-1) ynew = interpolate.splev(xs,tck,der=0) plt.figure() plt.plot(xs,ynew,x,y,'x')

  • Performance analysis strategies

    - by Bernd
    I am assigned to a performance-tuning-debugging-troubleshooting task. Scenario: a multi-application environment running on several networked machines using databases. OS is Unix, DB is Oracle. Business logic is implemented across applications using synchronous/asynchronous communication. Applications are multi-user with several hundred call center users at peak time. User interfaces are web-based. Applications are third party, I can get access to developers and source code. I only have the production system and a functional test environment, no load test environment. Problem: bad performance! I need fast results. Management is going crazy. I got symptom examples like these: user interface actions taking minutes to complete. Seaching for a customer usually takes 6 seconds but an immediate subsequent search with same parameters may take 6 minutes. What would be your strategy for finding root causes?

  • jquery loop to create elements

    - by Andy Simpson
    Dear all, I have had no luck with this task so far so grateful for any help. I have an html form, in which there is a small select menu (1-10) ie <select> <option value = '1'>1</option> <option value = '2'>2</option> ... <option value = '10'>10</option> </select> depending on what value is selected i would like jquery to create (or remove) that number of input text boxes (with different names and id's). eg if 2 was selected these inputs would be created: <input type = 'text' name = 'name1' id = 'id1' /> <input type = 'text' name = 'name2' id = 'id2' /> i look forward to your no doubt simple and elegant solutions! andy

  • NUnit vs Visual Studio 2010's MSTest?

    - by David White
    I realise that there are many older questions addressing the general question of NUnit v MSTest for versions of Visual Studio up to 2008 (such as this one). Microsoft have a history of getting things right in their 3rd version. For MSTest, that is VS2010. Have they done so with MSTest? Would you use it in a new project in preference to NUnit? My specific concerns: speed running tests within CruiseControl.NET (either commandline or MSBuild task) code coverage reports from CC.NET can you run MSTest tests in debug mode (We use ReSharper, so test-runners are not an issue for us. We have used NUnit for the last few years. We do not have TFS.)

  • How to utilize my computation resources.

    - by carter-boater
    Hi all, I wrote a program to solve a complicated problem. This program is just a c# console application and doesn't do console.write until the computation part is finished, so output won't affect the performance. The program is like this: static void Main(string[] args) { Thread WorkerThread = new Thread(new ThreadStart(Run), StackSize); WorkerThread.Priority = ThreadPriority.Highest; WorkerThread.Start(); Console.WriteLine("Worker thread is runing..."); WorkerThread.Join(); } Now it takes 3 minute to run, when I open my task manager, I see it only take 12% of the cpu time. I actually have a i7 intel cpu with 6G three channel DDR3 memory. I am wondering how I can improve the utilization of my hardware. Thanks a lot

    - by haansi
    hello, We have to do a project which is a web based workflow application. I have never used WWF. I am thinking should we use WWF with asp.net ?

I am not getting will it hard to switch to WWF ? (we have short time to deliver/ learning curve) Please advice on this. thanks

  • Hadoop 0.2: How to read outputs from TextOutputFormat?

    - by S.N
    My reducer class produces outputs with TextOutputFormat (the default OutputFormat given by Job). I like to consume this outputs after the MapReduce job complete to aggregate the outputs. In addition to this, I like to write out the aggregated information with TextInputFormat so that the output from this process can be consumed by the next iteration of MapReduce task. Can anyone give me an example on how to write & read with TextFormat? By the way, the reason why I am using TextFormat, rather Sequence, is the interoperability. The outputs should be consumed by any software.

  • Java Meta Search Engine API

    - by Loki
    I'm currently researching Java libraries to help in building a meta type search engine in the sense of being able to replace any given search engine in the back-end of the application or to simultaneously search using multiple search engines. I'm not interested in the GUI part here, just the generalization of search engine APIs and usage. I'd like to know about the common libraries used to achieve this task and if there are any common patterns used in this case. I imagined that this problem is common enough to be able to find plenty of stuff on Google, but it seems like search is a very proprietary domain and not much information is fed back to the community.

  • How do you pass variables to class_eval in ruby?

    - by klochner
    I'm working on a metaprogramming task, where I'm trying to use a single method to define a polymorphic association in the calling class, while also defining the association in the target class. I need to pass in the name of the calling class to get the association right. Here's a snippet that should get the idea across: class SomeClass < ActiveRecord::Base has_many :join_models, :dependent=:destroy end class JoinModel < ActiveRecord::Base belongs_to :some_class belongs_to :entity, :polymorphic=true end module Foo module ClassMethods def acts_as_entity has_many :join_models, :as=:entity, :dependent=:destroy has_many :some_classes, :through=:join_models klass = self.name.tableize SomeClass.class_eval "has_many :#{klass}, :through=:join_models" end end end I'd like to eliminate the klass= line, but don't know how else to pass a reference to self from the calling class into class_eval. any suggestions?

  • sql server 2008 notifications

    - by Alexander Stalt
    C#, VS 2005, Sql Server 2008 I have a database on a remote server. It has a table table1. Several clients works with it. Every(each?) client can change content of table1. Every(each?) client must represent actual content of this table. So I need some algorythm (pattern) to keep clients represent actual content of table1. I know that sql server 2008 supports notification mechanism (reporting services). How can I use it for my task ?

  • How can I encode four unsigned bytes (0-255) to a float and back again using HLSL?

    - by Statement
    Hello! I am facing a task where one of my hlsl shaders require multiple texture lookups per pixel. My 2d textures are fixed to 256*256, so two bytes should be sufficient to address any given texel given this constraint. My idea is then to put two xy-coordinates in each float, giving me eight xy-coordinates in pixel space when packed in a Vector4 format image. These eight coordinates are then used to sample another texture(s). The reason for doing this is to save graphics memory and an attempt to optimize processing time, since then I don't require multiple texture lookups. By the way: Does anyone know if encoding/decoding 16 bytes from/to 4 floats using 1 sampling is slower than 4 samplings with unencoded data?

  • Developing for the iPhone outside Xcode

    - by Federico Builes
    I'd like to develop and run my iPhone applications from the command line and my personal editor instead of having to use Xcode. So far I've been able to edit all the files in Emacs and run xcodebuild in the project to compile/link/etc. The next step would be to create a Makefile task to launch the iPhone Simulator with my current application. Any ideas of how can I do that? Update: I'm not interested in XCode calling my editor, I just want to forget about the IDE as much as I can.

  • WPF Statusbar Updates - help, I seem to be going round in circles

    - by David Ward
    I seem to be going round in circles. I have a WPF application that has a main ribbon window with a status bar. When you navigate to a "view" a user control is displayed as the content of the main window. The view has a ViewModel which handles retrieving data from the database and the View's datacontext is set to the ViewModel. What I want is to have the lengthy operation (data retrieval) run on a background thread and whilst it is running the status in the main window to report appropriately. When the background task is complete, the status should revert back to "Ready" (much the same as Visual Studio). How should I wire this together so that I can have the data access code separated out in the ViewModel whilst keeping a responsive UI? I have tried using the BackgroundWorker is various places in the code and I still end up with an unresponsive UI.

  • Best practice in this situation?

    - by Steve
    My Delphi program relies heavily on Outlook automation. Outlook versions prior to 2007-SP2 tend to get stuck in memory due to badly written addins and badly written Outlook code. If Outlook is stuck, calling CreateOleObject('Outlook.Application') or GetActiveObject ... doesn't return and keeps my application hanging till Outlook.exe is closed in the task manager. I've thought of a solution, but I'm unsure whether it's good practice or not. I'd start Outlook with CreateOleObject in a separate thread, wait 10 seconds in my main thread and if Outlook hangs (CreateOleObject doesn't return), offer the user to kill the Outlook.exe process from my program. But since I don't want to force the user to kill the Outlook.exe proccess, as an alternative I also need a way to kill the new thread in my program which keeps hanging now. My questions are: a, Is this good practice b, How can I terminate a hanging thread in Delphi without leaking memory? Is there a way?

  • Is it possible to force an error in an Integration Services data flow to demonstrate its rollback?

    - by Matt
    I have been tasked with demoing how Integration Services handles an error during a data flow to show that no data makes it into the destination. This is an existing package and I want to limit the code changes to the package as much as possible (since this is most likely a one time deal). The scenario that is trying to be understood is a "systemic" failure - the source file disappears midstream, or the file server loses power, etc. I know I can make this happen by having the Error Output of the source set to Failure and introducing bad data but I would like to do something lighter than that. I suppose I could add a Script Transform task and look for a certain value and throw an error but I was hoping someone has come up with something easier / more elegant. Thanks, Matt

  • How can I find the program making a harmonica sound?

    - by Josh
    A friend has a Windows XP SP3 machine that plays a harmonica sound for about 5 seconds throughout the day at what seems to be random intervals (every couple hours). My question is how can I find the program making this sound? Is there a Windows API hook for monitoring audio access? I've gone through and checked all the standard Windows sounds in the Control Panel and right now the theme is set to no sounds and I personally checked to make sure none of the events have a sound specified. I also checked the Task Scheduler to make sure there wasn't something scheduled to go off every couple hours. Any ideas on how to go about finding the bugger?

  • Pass NSMutableArray between two UIViewController's

    - by aahrens
    I have two view controllers name RootViewController and SecondViewController. In the FirstViewController I have this NSMutableArray @interface RootViewController : UITableViewController { NSMutableArray *allClasses;}@property (nonatomic,retain) NSMutableArray *allClasses; In the RootViewController I populate the UITableView with all the objects within allClasses In my SecondViewController I have @interface SecondViewController : UIViewController <UITextFieldDelegate,UIPickerViewDelegate> { NSMutableArray *arrayStrings;} I have a method that adds new NSStrings to the arrayStrings. My goal is to be able to pass the arrayStrings to the RootViewController by trying something similar to allClasses = arrayStrings. That way when the RootViewController is loaded it can populate with new information. How would I got about accomplishing that task?

  • MVC pattern and State Machine

    - by topright
    I think of a game as a state machine. Game States separate I/O processing, game logic and rendering into different classes: while (game_loop) { game->state->io_events(this); game->state->logic(this); game->state->rendering(); } You can easily change a game state in this approach. MVC separation works in more complex way: while (game_loop) { game->cotroller->io_events(this); game->model->logic(this); game->view->rendering(); } So changing Game States becomes error prone task (switch 3 MVC objects, not 1). What are practical ways of combining these 2 concepts?
