• Creating and Using a jQuery Plug-in in ASP.NET Web Forms

  - by bipinjoshi

  Developers often resort to code reuse techniques in their projects. As far as ASP.NET framework server side programming is concerned classes, class libraries, components, custom server controls and user controls are popular code reuse techniques. Modern ASP.NET web applications no longer restrict themselves only to server side programming. They also make use of client side scripting to render rich web forms. No wonder that Microsoft Visual Studio 2010 includes jQuery library by default as a part of newly created web site. If you are using jQuery for client side scripting then one way to reuse your client side code is to create a jQuery plug-in. Creating a plug-in allows you to bundle your reusable jQuery code in a neat way and then reuse it across web forms. In this article you will learn how to create a simple jQuery plug-in from scratch. You will also learn about certain guidelines that help you build professional jQuery plug-ins.http://www.bipinjoshi.net/articles/aae84a03-b4a8-477d-b087-5b7f42935220.aspx

• Parallel Computing in .Net 4.0

  - by kaleidoscope

  Technorati Tags: Ram,Parallel Computing in .Net 4.0 Parallel computing is the simultaneous use of multiple compute resources to solve a computational problem: To be run using multiple CPUs A problem is broken into discrete parts that can be solved concurrently Each part is further broken down to a series of instructions Instructions from each part execute simultaneously on different CPUs Parallel Extensions in .NET 4.0 provides a set of libraries and tools to achieve the above mentioned objectives. This supports two paradigms of parallel computing Data Parallelism – This refers to dividing the data across multiple processors for parallel execution.e.g we are processing an array of 1000 elements we can distribute the data between two processors say 500 each. This is supported by the Parallel LINQ (PLINQ) in .NET 4.0 Task Parallelism – This breaks down the program into multiple tasks which can be parallelized and are executed on different processors. This is supported by Task Parallel Library (TPL) in .NET 4.0 A high level view is shown below:

• Why would I want to install node.js in my Rails Application?

  - by Crazy JIm

  Okay guys, I'm super confused. I thought node.js was a sever side framwork, basically the js version of Ruby's Rails or PHP's Zend. However, I'm having some difficulty with turbolinks, and it seems to be the way to fix it is through installing node.js I mean, I don't understand this at all. How can two frameworks work together like this? Also, it's not a gem (that REALLY would have confused me), you have to install node.js it onto your local machine by running (in the case of Ubuntu) sudo apt-get install nodejs Firstly, how does this totally separate framwork have any bearing on rails? Secondly, surely this isn't fixing the problem forever? When you specify a gem in your gemfile, the server knows what external libraries to install. How does the server know to install nodejs?

• Artificial Intelligence implemented in x86 Assembly? [closed]

  - by Bigyellow Bastion

  Okay, so I decided that for my upcoming operating system, I do basically everything in x86 Assembly, using only 16-bit mode. I will need to write the software to host on it once I have something up and going, and I'll definitely post the source and VM-executable file. But as for now I'm stuck with the idea of implementing the AI code for some of the games I'm making to host on it. AI in Assembly is tedious, and sometimes almost impossible seeming, especially complex AI(I'm talking SNES Super Mario World 2: Yoshi's Island AI here, by the way, not pong AI). I was thinking that it'd be such a hassle that I'd have to bring a higher-level language to work some of this out here, like maybe C++ or C#, but I'd have to go through more work linking it into a fine binary that my OS will host, and that adds unnecessary work to the table I wanted to avoid(I don't want a complex system, I want everything as bare-bones as possible, avoiding libraries, APIs, and linkable formats for now, to make everything more directly accessible to the kernel's API).

• Preventing adult content in a forum

  - by John Doe

  I'm working on a forum that allows images attached to the posts and doesn't require registration. Thing is, I'd like to provide a work-safe navigation option in which the posts with porn images attached aren't shown. The ideas I've come up with are: Making the work-safe option the default and treating all posts with images attached as pornographic, and making them visible only if the user "unchecks" it. Making all posts with images attached not work-safe by default and changing their status to work-safe only after a moderator approved it. Only then they would be visible if the user has the "work-safe" option checked. Does anyone else have an idea? Also, how the big web services deal with this? (YouTube, CraigsList, even StackExchange). By the way, I don't think that "nudity detector" libraries are accurate and they give plenty of false positives and negatives. Thanks!

• Zune API Library for Ruby

  - by kerry

  Those of you who know me, know my favorite music player is the Zune. For some reason it seems most of my spare time lately seems to be creating Zune API libraries for different languages (I have a PHP one as well).  Here’s another one for Ruby!  If you use it, let me know.  I would love to hear what people are working on. It’s hosted at github, and very easy to use. zune_card = Zune::ZuneCard.for('a_zune_tag') Checkout the README for deets on what fields the object will have.

• Importing a windows project into android using cocos2d-x

  - by Ef Es

  What I am trying to do today is to import a full project to Android, but no tutorials are available for that that I have seen. My approach was to create a new android project, copy all the classes and resources in the folders and calling ./build_native.sh but I get an error because most of the files are not being included in the project. I tried opening the Android.mk and I can see why "LOCAL_SRC_FILES := AppDelegate.cpp \ HelloWorldScene.cpp" are the only files linked. Should I manually modify the make file or can it be automated by some way I don't know? Thank you. UPDATE: I manually added all files and headers to the make file and I get errors linking Box2D or cocosdenshion libraries.

• Animation file format

  - by Paul

  I'm trying to make a simple 2D animation file format. It'll be very rudimentary: only an XML file containing some parameters (such as frame duration) and metadata, and some images, each representing a frame. I'd like to have the whole animation (frames and XML document) packed in a single file. How do you suggest I do that? What libraries are there that would allow easy access to the files inside the animation file itself? The language I'm using is C++ and the platform is Windows, but I'd rather not use a platform dependent library, if possible.

• Is programming too easy if compared to other fields?

  - by Shashank jain

  I have been programming since some years and I won't say its a piece of cake but in this field, you know how to do things. You can always google up resources, tutorials. There are tons of already written code to help you with - frameworks, libraries but if you compare it to other innovation fields like "Electronics". Its not too easy to get started with, the community might not be too large on the internet, getting the things right plus lets not forget there is nothing to tell you where the error might be. I have wanted many times but not be able to get into, like, building some kind of robot because I don't know how to start. So my question is that, does programming tends to be easy compared rest of the fields or is it just my intrest that makes it easy?

• How did programmers resolve their problems before the internet?

  - by 9a3eedi

  When programming, anytime I get stuck, perhaps with a compiler error that doesn't make sense, or from a GUI function that didn't do what I expected, I automatically google my problem, find someone else that faced the same thing, and read what's going on and why I'm getting the problem. Before the internet, how did people handle these situations? People used to read books and manuals more, I know. But books don't explain everything, like the odd compiler problem that you get sometimes, or nothing showing up on your screen despite you clearly writing correct OpenGL code. How did people cope when facing challenges? Did they simply "bash their head" on the wall till they figured it out? Is there something people used to do regularly on the side that gave them the ability to get themselves unstuck more easily? Were libraries/compilers much simpler back then? I've been asking this question because I sometimes feel guilty depending on Google so much when I'm pretty sure programmers before my time were more independent when it comes to facing these matters.

• Role of linking, object files and executables

  - by Tim

  For a C or assembly program that does not require any other library, will linking be necessary? In other words, will conversion from C to Assembly and/or from Assembly to an object file be enough without being followed by linking? If linking is still needed, what will it do, given that there is just one object file which doesn't need a library to link to? Relatedly, how different are object files and executable files, given that in Linux, both have file format ELF? Are object files those ELF files that are not runnable? Are there some executable files that can be linked to object files? If yes, does it mean dynamical linking of executables to shared libraries?

• Pros and cons of hosted scripts

  - by P.Brian.Mackey

  I have seen some developers use hosted scripts to link their libraries. cdn.jquerytools.org is one example. I have also seen people complain that a hosted script link has been hijacked. How safe is using hosted scripts in reality? Are the scripts automatically updated? For example, if jQuery 5 goes to 6 do I automatically get version 6 or do I need to update my link? I also see that Google has a large set of these scripts setup for hosting. What are the pros and cons?

• Is making my own copyright licence safe?

  - by abcd

  I've seen various open source libraries (actually I've seen it for assets as well) having a home-baked license in the following manner : SomeGuy's License:1. You can use this code freely in commercial projects and modify it as you wish, but not sell it2. If you want to sell a modified version, drop me an email first, or give credits to me Edit: The above example is ambiguous, so I am giving another one, I want to know if 3 lines of license will hold some ground: SomeGuy's License:1. You can use this code in a commercial project as a 3rd party library2. You can't sell it as a derivative work I know that such license is not polished at all, for example the Creative Commons set of licenses seem to be short, but actually have some large legal stuff underneath it, but I wonder if at least some level of protection can be gained with a hobby license like that ? My question is, could this hold any ground in the court, or would the corporative lawyers of the company X tear it apart ?

• Why fork a library for your own application?

  - by Mr. Shickadance

  Why should a programmer ever fork a library for inclusion in a widely used application? I ask this question because I was reading an article about why Chromium isn't packaged for many Linux distros like Fedora. Apparently its largely due to the fact that Google has forked a number of libraries, modified them, and included them in Chromium. This has driven up the complexity of packaging releases. There are a number of reasons why this can be a bad thing, but how strong a case can you actually make for doing so in a large widely used application such as Chromium? The original article: http://ostatic.com/blog/making-projects-easier-to-package-why-chromium-isnt-in-fedora Isn't it usually worth the effort to make slight modifications to your own program in order to use a popular and well developed library?

• How and why to create -dbg, -dev, -doc packages?

  - by Nico

  I'm writing an Ubuntu package for a package which essentially provides a number of libraries and headers which then be used to build other software. The package also breaks up in smaller subpackages which are interdependent; in this sense the package is quite similar to boost. I noticed that packages like boost provide [...] libboost-dbg libboost-dev libboost-doc [...] libboost-all-dev [...] but nothing that goes by the name boost or libboost. What is the idea behind this? What are the purposes of the -dbg, -dev, and -doc packages? Are there any instructions provided on how to write build files for those packages?

• Future of a ServiceStack based Solution in the Context of Licensing

  - by Harindaka

  I just want someone to clarify the following questions as Demis Bellot had announced a couple of weeks ago that ServiceStack would go commercial. Refer link below. https://plus.google.com/app/basic/stream/z12tfvoackvnx1xzd04cfrirpvybu1nje54 (Please note that when I say ServiceStack or SS I refer to all associated SS libraries such as ServiceStack.Text, etc.) If I have a solution already developed using ServiceStack today will I have to purchase a license once SS goes commercial even if I don't upgrade the SS binaries to the commercial release version? Will previous versions of SS (prior to commercial licensing) always be opensource and use the same license as before? If I fork SS today (prior to commercial licensing) on Github, would it be illegal to maintain that after SS goes commercial? If the answer to question 2 is yes, then would I still be able to fork a previous version after SS goes commercial without worrying about the commercial license (all the while maintaining and releasing the source to the public)?

• Unable to access jar. Why?

  - by SystemNetworks

  I was making a game in java and exported it as jar file. Then after that, I opeed jar splice. I added the libaries and exported jar. I added the natives then i made a main class. I created a fat jar and put it on my desktop. I'm using Mac OS X 10.8 Mountain Lion. When I put in the terminal, java -jar System Front.jar it says unable to access System Front.jar Even if i double click on the file, it doesen't show up! Help! I'm using slick. I added slick and lwjgl as libraries for the jar splice at the jars.

• Getting started with ClojureScript and Google Closure

  - by Andrea

  I would like to investigate whether ClojureScript, with the associated Google Closure library is a reasonable tool to build modern, in-browser, Javascript applications. My current Javascript stack consists of jQuery, Backbone and RequireJS with the possible additions of some widgets libraries like jQueryUI or KendoUI. So it will be quite a big leap (I already know how to work in Clojure, although I have little experience). What is a good roadmap to do so? Should I learn the Google Closure library first, or can I grasp it together with ClojureScript? One thing I am concerned about is the overall application structure. Backbone is rather opinionated on how to organize your application. I am not sure whether Google Closure also includes some components to help with the design of the application. And, if this is the case, I do not know how to tell whether this structure will port to ClojureScript or a ClojureScript application will require a different organization anyway, and only use - say - the widgets and DOM manipulation features of Closure.

• For what types of applications is Python a bad choice?

  - by Casey Patton

  I just started learning Python, and I'd like to get some more context on the language. I realize that Python is a slow language relative to C or C++, etc. Thus, Python is probably not the best choice for applications that need to run quickly. Outside of this, it seems like Python is a great general purpose language that is easy to read and write. The available libraries give it a huge amount of functionality. Outside of performance critical applications, where is it a bad choice to use Python (and why)?

• Resources on concepts/theory behind GUI development?

  - by ShrimpCrackers

  I was wondering if there were any resources that explain concepts/theory behind GUI development. I don't mean a resource that explains how to use a GUI library, but rather how to create your own widgets. For example a resource that explains different methods on how to implement scrollable listboxes. I ask because I have an idea for a game tool where I would like to create my own widgets and let users drag and drop them onto some kind of form. How do GUI libraries usually draw widgets? I'm not sure if reskinning widgets from a GUI library fits my needs, since widget behavior needs to be dynamic based on user interaction.

• Digikam: What's the problem?

  - by Unapiedra

  I installed Digikam by using the Philip5-PPA. When I run it I get the error below. This is by running it through gdb: Starting program: /usr/bin/digikam /usr/bin/digikam: error while loading shared libraries: libcxcore.so.2.1: cannot open shared object file: No such file or directory [Inferior 1 (process 29894) exited with code 0177] What should I do to find the error and fix it? I can see that somehow libcxcore.so.2.1 is wanted but not found. Is this an error of the PPA, or can I simply point it in the right direction? Can I raise an issue with the PPA creator through launchpad? Some next steps would be quite helpful.
