  • django multi-language (i18n) and seo

    - by fumer
    hi, I am developing a multi-language site in django. In order to improve SEO, i will give every language version a unique URL like below, english: www.foo.com/en/index.html french: www.foo.com/fr/index.html chinese: www.foo.com/zh/index.html However, Django looks for a "django_language" key in user's session or cookie to determine language in default, so,Despite which language user chose, URL is always the same. for instance: http://www.foo.com/index.html how to resolve this problem ? thank you!

  • How to get the time on the point that you click on the clock?

    - by Jeff
    For instance, when you click the clock on the screen, there will pop up a notification/dialog which displays the exact time point. Anyone can tell me how to achieve this function? Thanks in advance! Maybe I should explain the "exact time point" . For example, there is a big analog clock on the screen. When you click around the dial, it will pop up a dialog box to display the exact time.

  • PHP detecting filesystem encoding

    - by Evert
    Hi guys, I need to save files with non-latin filenames on a filesytem, using PHP. I want to make this work cross-platform. How do I know what encoding I can use to write the file? I understand many modern filesystems are UTF-8 based (is this correct?), but I doubt Windows XP is (for instance). So, is there a robust detection mechanism? Evert

  • New to MVC. Actionscript 3.0 Appreciate your help.

    - by Combustion007
    Hello Everyone, I am new to design patterns and am trying to learn the MVC implementation. I have written four classes: DataModel DataView DataController Main Main serves as the application facade. The main FLA is called HelloWorld. I have a symbol called "Box" in HelloWorld. I just would like to add an instance of the "Box" on the stage. Eventually I would like to place a button and when the button is clicked, the Box instance color will be changed. I would appreciate any help, please help me figure out what am I doing wrong. Here are my Classes: DATAMODEL CLASS: package { import flash.events.*; public class DataModel extends EventDispatcher { public static const UPDATE:String = "modelUpdate"; private var _color:Number = (Math.round(Math.random()* 0xffffff)); public function DataModel() { trace("DATA MODEL INIT"); } public function get color():Number { return _color; } public function set color(p:Number):void { _color = p; notifyObserver(); } public function notifyObserver():void { dispatchEvent(new Event(DataModel.UPDATE)); } } } //DATACONTROLLER CLASS: package { import flash.events.; import flash.display.; import flash.errors.*; public class DataController { private var _model:DataModel; public function DataController(m:DataModel) { trace("DATACONTROLLER INIT"); _model = m; } } } DATAVIEW CLASS: package { import flash.events.; import flash.display.; import flash.errors.*; public class DataView extends Sprite { private var _model:DataModel; private var _controller:DataController; private var b:Box; public function DataView(m:DataModel, c:DataController) { _model = m; _controller = c; b = new Box(); b.x = b.y = 100; addChild(b); } } } And Finally THE FACADE: package { import flash.display.; import flash.events.; import flash.text.; import flash.errors.; public class Main extends Sprite { private var _model:DataModel; private var _controller:DataController; private var _view:DataView; public function Main(m:DataModel, c:DataController, v:DataView) { _model = m; _controller = c; _view = v; addChild(v); } } } When I test the movie: I get this error: ArgumentError: Error #1063: Argument count mismatch on Main(). Expected 3, got 0. Thanks alot.

  • Doubleton Pattern Implementation

    - by Pierreten
    I'm leveraging the Doubleton Pattern from this link http://www.codeproject.com/KB/architecture/designpattern_doubleton.aspx in my own code. I think it makes things a lot easier since the Singleton only provides one instance, but I get two with this pattern. I was wondering if it would make sense to have it implement an interface so I can inject it into my domain layer.

  • Assigning IDs to instances of a class (Pythonic)

    - by mellort
    I want to have each instance of some class have a unique integer identifier based on the order that I create them, starting with (say) 0. In Java, I could do this with a static class variable. I know I can emulate the same sort of behavior with Python, but what would be the most 'Pythonic' way to do this? Thanks

  • Connect to MySQL via PHP script tunnel

    - by Neo
    Here's the question, I need to connect to a remote MySQL database from my C# Application, problem is the MySQL instance will block all access to all IP's apart from localhost, this can not be changed as its too much of a security issue. The question is, is it possible to connect via a tunnel instead to a php script hosted on the server, this would then act as the mysql connection. Any ideas and suggestions?

  • Setting column width in Table View

    - by Jeremy
    I am having a hard time understanding how to change the width of columns when creating a table view. I know you can set the width in pixels of a column but that is not what I want to do. Say, for instance, I have 2 columns and want each column to take up half the screen. How do I do this without explicitly setting the pixels, so that my code can work on multiple screen sizes?

  • Get color output in bash

    - by Werner
    Hi, when compiling some projects on linux terminal, I get usually a long output consisting of a lot of information. Usually this information is MONOCHROME. I wonder if bash can be modified somehow, so in all outputs or in some specific outputs (like from Makefile, etc) I can get different colors dependeing on, for instance: make[1]: Leaving directory or g++ -DHAVE_CONFIG_H -I. etc. Thanks

  • Append or modify keys in conf files using sed/bash one-liner

    - by Jeff
    I often have to modify files such as sysctl.conf, and I'm familiar with using sed to replace existing values. Is there a way to append the new key/value pair to the file if sed wasn't able to replace it? For instance, using this example: modify config file using bash script sed -c -i "s/\($TARGET_KEY *= *\).*/\1$REPLACEMENT_VALUE/" $CONFIG_FILE How could I add the $TARGET_KEY = $REPLACEMENT_VALUE new line to $CONFIG_FILE using the same sed expression with slight changes? And on a related topic, how can I force creation of $CONFIG_FILE if it didn't exist?

  • How to play music on site preventing direct file download

    - by Hugo Palma
    I'm starting a blog with a hosted wordpress instance and i would like to be able to stream music using a flash player on some posts. The problem is that every player i find uses a simple param to get the file url which makes it very easy for someone to find that url and just download the file. A server side solution can be implemented as i have full access to the server.
