  • How can I create a content widget generator?

    - by Richard
    Sites like Buzzfeed offer widgets (Javascript, PHP, WordPress, etc.) for syndicating their content on other sites. Does anyone have any ideas on how I could go about creating/implementing some kind of interactive widget generator that gives users options for customizing their widget? I assume this would require RSS. Check out the Buzzfeed generator to see what I mean http://www.buzzfeed.com/network/widget

  • Get/Post Controller Logic Best Practice

    - by Brian Mains
    In an ASP.NET MVC project (Razor), I have a Get request, which loads two properties on a model, dependent on the property passed into the action method. So if the parameter has a value, the Group property is supplied data. But if not, the Groups collection property is supplied data. In the post action method, when I process the data, to repopulate the view, I have to provide similar logic, and could getaway with returning Action(param) (the get response) to the caller. My question is, based on experience, is that a good practice to get into? I see some downsides to doing that, but adds the lack of code redundancy. Or is there a better alternative?

  • Using "public" vars or attributes in class calls, functional approach

    - by marw
    I was always wondering about two things I tend to do in my little projects. Sometimes I will have this design: class FooClass ... self.foo = "it's a bar" self._do_some_stuff(self) def _do_some_stuff(self): print(self.foo) And sometimes this one: class FooClass2 ... self.do_some_stuff(foo="it's a bar") def do_some_stuff(self, foo): print(foo) Although I roughly understand the differences between functional and class approaches, I struggle with the design. For example, in FooClass the self.foo is always accessible as an attribute. If there are numerous calls to it, is that faster than making foo a local variable that is passed from method to method (like in FooClass2)? What happens in memory in both cases? If FooClass2 is preferred (ie. I don't need to access foo) and other attributes inside do not change their states (the class is executed once only and returns the result), should the code then be written as a series of functions in a module?

  • Dates set according to location not chosen language

    - by aspersieman
    I recently installed Ubuntu 13.10 chose my location as Thailand/Bangkok, keyboard layout and language as South African English. Everything seems to be set up correctly except wherever a date is displayed it is displayed in Thai, instead of English. This is most noticeable in the clock indicator (see images included for what I mean). How can I change my dates to English (South African locale if possible).

  • Checking For Empty Enumerations

    While spelunking in some code recently I saw a method that looked something like this: public void Foo<T>(IEnumerable<T> items) { if(items == null || items.Count() == 0) { // Warn about emptiness } } This method accepts a generic enumeration and then proceeds to check if the enumeration is null or empty. Do you see the potential problem with this code? Ill give you a hint, its this line: items.Count() == 0 Whats the problem? Well that line right there has the potential...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Main class passes dbConn obj to all its services, I need to change the dbConn for one of its services. - suggestion for design pattern

    - by tech_learner
    There is this main class and there are several services ( which uses db connection to retrieve data ) These services are initialized in the main class db properties are obtained from the property file and then dbconnection is opened by calling a method dbOpen() written in the main class and the resultant connection object is set to the service objects by iterating through the list of services and by calling setConnection method on the service note: that the services are instantiated in the main class and the main class is not a superclass for services. I also need to mention that there is this recycle db connection scenario only main class is aware of. /** connects to DB, optionally recycling existing connection), * throws RuntimeException if unable to connect */ private void connectDb(boolean recycle) { try { if (recycle) { log.status( log.getSB().append("Recycling DB Connection") ); closeDb(); } openDb(); for ( int i = 0 ; i < service.length ; i++ ) { service[i].setConnection(db); } } One of the service needs to use a different database, what is the best design pattern to use?

Could someone be using the our website to access SMTP for spamming purpose? UPDATE: Server info: Centos OS with CPanel and WHM. However no one has access to either. Taking a look at the logs it looks like someone repetitively attempted to login with a known existent user/pass.

  • Best way to reuse common functions between ASPX pages ?

    - by DFord
    I have a bunch of functions that are used across multiple ASPX files. I want to condense these down to one file to be used for all the ASPX files. I have a few ideas but I want to know what the accepted method to doing this would be. I have an idea to just create a class to put them in. However, I was wondering if i could put them in a ascx page, but that does not look like the solution I'm looking for. Is there a accepted method for this type of situation?

  • Bitmap & Object Collision Help

    - by MarkEz
    Is it possible to detect when an object and a bitmap collide. I have an arraylist of sprites that I am shooting with an image. I tried using this method here but as soon as the bitmap appears the sprite disappears, this is in the Sprite class: public boolean isCollision(Bitmap other) { // TODO Auto-generated method stub if(other.getWidth() > x && other.getWidth() < x + width && >other.getHeight() > y && other.getHeight() < y + height); return true; }

  • Encapsulating code in F# (Part 1)

    - by MarkPearl
    I have been looking at F# for a while now and seem a few really interesting samples and snippets on howto’s. This has been great to see the basic outline of the language and the possibilities, however a nagging question in the back of my mind has been what does an F# project look like? How do I code group code in F# so that it can be modularized and brought in and out of a project easily? My Expert F# book has an entire chapter (7) dedicated to this and after browsing the other chapters of the book I decided that this topic was something I really wanted to know more about now! Because of my C# background I keep trying to think in F# of objects. So to try and get a clearer idea of how to do things the F# way I am first going to take a very simplified C# example and try to “translate” it. using System; namespace ConsoleApplication1 { namespace ExampleOfEncapsulationInCSharp { class Program { static void EncapsulatedVariableInAMethod() { int count = 10; Console.WriteLine(count); } static void Main(string[] args) { EncapsulatedVariableInAMethod(); Console.ReadLine(); } } } } From the above example the count integer is encapsulated within EncapsulatedVariableInAMethod method. You couldn’t access the count variable from outside the scope of its parent method but have full access to it within the method. Lets look at my F# equivalent… open System let EncapsulatedVariableInAMethod = let count = 10 Console.WriteLine(count) () EncapsulatedVariableInAMethod Console.ReadLine()   Now, when I first attempted to write the F# code I got stuck… I didn’t have the Console.WriteLine calls but had the following… open System let EncapsulatedVariableInAMethod = let count = 10 EncapsulatedVariableInAMethod Console.ReadLine()   The compiler didn’t like the let before the count = 10. This is because every F# expression must evaluate to a value. If I did not want to make the Console call, I would still need to evaluate the expression to something – and for this reason the Unit Type is provided. I could have done something like…. open System let EncapsulatedVariableInAMethod = let count = 10 () EncapsulatedVariableInAMethod Console.ReadLine()   Which the compiler would be happy with…

  • How do I get HDMI out working on an Acer AC700 HDMI?

    - by Kyle
    I have installed Ubuntu on my Acer AC700 (Chromebook) using both the Cr-48 method and the script method both of which I think are the same. The only thing that does not work is HDMI out. I assume this is because it uses the Chrome OS kernel to boot so I have hoped that eventually it would update and work. I'm currently running 12.04 with Kernel 3.4.0 and still no luck. I've tried booting in recovery for Ubuntu and attempting to get Xorg to generate a new config but I don't know enough to do anything else and that didn't work. Am I the only one out there? Is there no one else who wants this to be possible Any help is greatly appreciated.
