  • What is the best and cheapest CMS for an E-Commerce site?

    - by kf0l
    My client needs a site customers can use to pay the membership fees and join. It should also track when old members need to pay again. There are some members that will not want to pay online and they want to be able to use the site to manage all payments. The CMS must be cheap to host online, potentially with something like GitHub/Heroku. I am experienced with PHP and RoR. I am using a CMS so once I am done with this project it is easy for them to update. After reading through different posts I think WordPress with an e-commerce Plugin may be the right solution. Spree and WebGUI also looks promising. Thanks for the help.

  • Are there any surveys on to what degree developers like or hate scrum?

    - by dparnas
    Background: During a conference an analyst pointed out in a tweet that developers hate scrum. Myself and another person responded that this was not the case, and started discussing different scenarios on why developers would dislike scrum. One of the scenarios where that lazy developers are not able to hide in a scrum project. They are constantly challenged by the team to contribute. This discussion resulted in a blog post and video http://elsewhat.com/2010/05/20/lazy-developers-hate-agile-and%C2%A0scrum/ I've gotten three comments which I've tried to answer in a neutral way, but they comments do point out that there are some people who loathe scrum (and I am always 100% certain they are not lazy developers). Question Have there ever been a survey among developers on to what degree developers like or hate scrum ?

  • How to access variables of uninitialized class?

    - by oringe
    So I've gone with a somewhat singleton approach to my game class: #include "myGame.h" int main () { myGame game; return game.Execute(); } But now I need to define a class that accesses variables in the instance of myGame. class MotionState { public: virtual void setWorldTransform (...) { VariableFromMyGameClass++; //<-- !? ...} }; I'm trying to integrate this class into my project from an example that just uses globals. How can I access variables of myGame class in the definition of new classes? Should I give up on my singleton approach?

  • lower graphics setting in ubuntu

    - by zkent
    First off, I am new to Ubuntu. I come from a Windows background (DOS before that) and am loving it so far. I installed it on an older Dell laptop that I wanted to get another year out of. I set this machine up primarily as a LAMP development machine for a project I am working on. The machine is a Vostro 1500 and it has 4GB RAM (maxed) and an upgraded hard drive. I can't watch YouTube videos for long before it starts to overheat and start acting sporadic. I can live without YouTube but every so often the application switching (alt-tab) gets slower and begins not showing all applications and the Dash home quits displaying properly. I am sure I am asking a lot of this old machine. What I really want to know is: are there any settings in Ubuntu that allow me to lower the graphic effects (fade-ins, transparencies, fancy transitions, etc) that would be less taxing on the video card?

  • The life saver HttpContext.Current.Items["ParameterName"]

    - by MoezMousavi
    I got stocked passing parameter to one master page for some reasons, seems the page lifecycle and dynamic loading of the master pages has got some issues with defining public properties in the masterpage within my project. It did not set my values and as a result, properties became useless. A collegue just mentioned using HttpContext. have a look what  MSDN saying "Encapsulates all HTTP-specific information about an individual HTTP request" http://msdn.microsoft.com/en-us/library/system.web.httpcontext.aspx HttpContext.Current.Items["ParameterName"] Also, Page.Items could do the same thing. Page.Items, "Gets a list of objects stored in the page context" http://msdn.microsoft.com/en-us/library/system.web.ui.page.items.aspx as your master page and content page are rendered as a single document anyway.

  • Should we use python 2.6 or 2.7 or 3.x?

    - by lamwaiman1988
    The version of python which I am using is 2.6, and there is a 2.7 and 3.x. Usually I use python for some trivial program/snippet. I realize there are some major difference between 2.x and 3.x. I would really like to know, if I am going to make a bigger project with python, which version of python should I use? Should I upgrade to 2.7, or go to 3.x or stay with 2.6? The decision should be based on these terms: Number of user in the internet as a community. More users mean more open-source package and help from them. Functionality. Support from official development team. Compatibility for existing module/package. Thanks!

  • Where can I find some Cocos2dx beginner tutorials?

    - by Skeith
    I have tried to start programing with Cocos2dx but I have no idea where to start and the tutorials are no very not very helpful. What I am looking for is some tutorials/guides on how to begin using cocos2dx for the total beginner. Things like how to setup a project and run it and how to do simple things like draw graphics on the screen, play sounds and get input. I am running on windows 7 and have been told by the Cocos2dx wiki that this may cause problems so if anyone has a solution to this that would also be helpful.

  • Open a popup window from Silverlight

    - by Emanuele Bartolesi
    Silverlight has a method called HtmlPage.PopupWindow() that opens new web browser window with a specific page. You can find this method in the namespace System.Windows.Browser. If you haven’t in your project, add a reference to System.Windows.Browser. The method HtmlPage.PopupWindow() has three parameters: Uri – location to browse String – the target window HtmlPopupWindowOptions – a class with the window options (full list of properties http://msdn.microsoft.com/en-us/library/system.windows.browser.htmlpopupwindowoptions(v=vs.95).aspx) For a security reason of Silverlight the call to HtmlPage.PopupWindow() is allowed through any user input like a button, hyperlink, etc. The code is very simple: var options = new HtmlPopupWindowOptions {Left = 0, Top = 0, Width = 800, Height = 600}; if (HtmlPage.IsPopupWindowAllowed) HtmlPage.PopupWindow(new Uri("http://geekswithblogs.net/"), "new", options); The property IsPopupWindowAllowed is used to check whether the window is enabled to open popup.

  • What is the primary use of Vertex Buffer Objects?

    - by sensae
    From what I've read, it seems VBOs are purely for performance. I'm working on a very rudimentary learning project in lwjgl and I'm just trying to figure out what more advanced features of the library I should be delving into, and what their use is. My understanding is that VBOs allow a person to keep vertexes in VRAM while they aren't currently being drawn in a scene. In my case, I'm just drawing quads and performance probably isn't a concern at all, but I'm trying to piece together what's happening under the hood. If I'm drawing quads directly, I'm drawing from the CPU memory, correct? Also, if I'm not doing any checks for visibility, does that mean I'm rendering absolutely everything in the "scene", regardless of whether its in view? Are VBOs a way to store objects and only render what's needed?

  • Do ALL your variables need to be declared private?

    - by shovonr
    I know that it's best practice to stay safe, and that we should always prevent others from directly accessing a class' properties. I hear this all the time from university professors, and I also see this all the time in a lot of source code released on the App Hub. In fact, professors say that they will actually take marks off for every variable that gets declared public. Now, this leaves me always declaring variables as private. No matter what. Even if each of these variables were to have both a getter and a setter. But here's the problem: it's tedious work. I tend to quickly loose interest in a project every time I need to have a variable in a class that could have simply been declared public instead of private with a getter and a setter. So my question is, do I really need to declare all my variables private? Or could I declare some variables public whenever they require both a getter and a setter?

  • Can my employer force me to backup my personal machine? [closed]

    - by Eric B
    Here's the background: Approximately 1.25 years ago, the company I work for was acquired by a larger 400 person company. Before acquisition (and today still) we are all remote employees using our own personal hardware for work-related duties (coding, email, etc). We are approximately 15 employees within the larger organization. Some time after acquisition, the now owning company was slapped with a civil lawsuit. Part of this lawsuit (discovery) is requiring them to retrieve & store from us any related information. Because we were a separate company up until acquisition, there is a high probability that our personal machines might contain information about what the lawsuit alleges (email, documents, chat logs?, etc). Obviously, this depends largely on the person's job function (engineer vs. customer support vs. CEO). All employees are being required to comply. Since acquisition (1.25 yrs), the new company has not provided us with company laptops/desktops. We continue to use personal hardware, licenses, etc for work. Email is via POP3s and not hanging around on the mail server - it's on everyone's client. Documents are spread across personal machines. So, now they want us each to backup our complete personal machines. They are allowing us to create a "personal" folder where we can place personal documents. That single folder will be excluded from backup. Of course, that means total re-arrangement of documents, etc. For most of us, 99% of the data on the machine is NOT related to work. So, what's the consensus? Should we comply? What is their recourse if we do not?

  • How to get some experience in a new programming language? [closed]

    - by BeCool
    I have commercial experience in one programming language but I want to make a switch to another programming language (C#/.NET). I am in full-time employment so whenever I get free time I read relevant books or use online resources available. My questions are - How do I develop experience in the new language of interest (without leaving current job)? The best way I find to learn is to develop a project - How do you / Where can you find new test projects which you can refer to in the interview (these don't have to be real projects but perhaps I can take the code with me in a usb stick as proof). Do you have any tips/advice for me regarding best way to switch career? My lanugauge of choice is C# - so c# related answers will be appreciated.

  • Implementing cache system in Java Web Application

    - by TGM
    I worked with JPA (Eclipselink implementation) and Hibernate. As I understand these two have great caching systems. I am interested in caching in a Web application and in order to better understand the process I'm trying to implement something on my own. Sadly, I cannot find any in depth documentation about this subject. I'm interested in things like high scalability, sharing memory on different machines and other important theoretical matters. Is there any tutorial or open project I could check out? Thank you! *LE: * I want to cache DB information in POJOs just like JPA or Eclipselink

  • Why do so many people dislike C++?

    - by General K
    Beginners and professional, on blogs, in forums and chatrooms - people say it everywhere: C++ oh dear god no The short form of the question: For what reason is C++ so widely disliked and people are horrified by the imagination of using it for some project? I have been using a lot of different languages, including C++ by now, and I can only say that I really like it. I'm far more horrified by Delphi than by C++. Actually, I find it's an almost perfect, compiled language! I've been doing a lot of different projects in C++ as well, ranging from 3D video games to webservers and emulators for old video game consoles. And I still do not see the problem everyone else seems to have with it! It was hard for me to get into it of course, as it is quite complex and has a lot of depth, but after that it's simply great.

  • How should I get my code ready for OpenSourcing it and putting it on GitHub?

    - by Sempus
    In a few weeks, my project is going to be finished and I want to start getting my code ready for other people to use it. I am going to be posting everything to GitHub so people can tweak it and hopefully make it better. I guess what I'm asking is, what would be the best way to make sure my code is sufficiently documented and worded right for other people to use? I know you should always comment everything and I'm going to be putting in the @params feature for every method, but are there any other tips in general?

  • Developing applications for iPhone, BlackBerry and J2ME in ASP.Net

    Hi, I would like to introduce you a new mobile application framework iPFaces for developing native, form-oriented applications. The aim of the solution is to screen the programmer completely out from the mobile platform itself, and transfer the entire application logic to the central application server level. Developers with experience with one of the supported Web technologies (ASP.Net, Java, and PHP) may start working with iPFaces virtually immediately. For more information, see the project...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Is a blob more efficient than a varchar for data that can be ANY size?

    - by BillyNair
    When setting up a database I want to use the most efficient data type for potentially fairly long data. Currently my project is to store song titles and thoughts pertaining to that song. Some titles might be 5 characters or longer than 100 characters and the thoughts could run pretty long. Is it more efficient to use a varchar set to 8000 or to use a blob? Is using a blob the same as a varchar, in that there is a set size it is allocated regardless of what it holds? or is it just a pointer and it doesn't really use much space on the table? Is there a certain set size of a blob in KB or is it expandable?

  • XNA + Windows Forms: How make them work together without making the trick of the custom GraphicsDeviceControl?

    - by Renann
    What I've found is a solution where you have to code a custom GraphicsDeviceControl to put inside the form (the well known tutorial from the APPHub), but that's not what I'm searching for. I would like to say that before start to right my question here, I "googled" a lot and I saw some questions here, but I couldn't find what I'm looking for. I would like to have the Draw/Update loops completly managed by XNAFrameWork (with XNA project and so), and not by a custom component. I hope you understand what I asked. Thanks in advance. Edit What's the most important thing for me and wasn't shown in the tutorial of APPHub is: where I have to put the input handling? That's one the problems that wasn't covered by the tutorial.

  • "Dogfooding" VS 2010 and .NET 4

    As we get ready for the launch of Visual Studio 2010 and .NET Framework 4, I find myself looking back at the project to think about some of the critical factors that lead to our success.    One of the things that stands out clearly for me is our practice of dogfooding the various pieces of Visual Studio throughout the product cycle.  Here at Microsoft, we use the term dogfooding to refer to the internal use of a pre-release product in our daily work - after all, until our product...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • RedStation.com is heaven for ddos attackers, How to file complaint?

    - by Ehsan
    Sorry, I don't know where to open this subject. This is not the first time we have faced with a massive DDOS attack from one of servers in RedStation.com and even after we had contacted with their abuse department with it's log there is no cooperation and they don't even like to bother themselves about it. and we don't know how to stop such activity. Do you know how to file complaint against this datacenter? we could not be patient anymore and see they are not care about such things on their network ? it seems like they are heaven for attackers now since they close their eyes to gain more money. I guess some global organization is missing in this matter to investigate such activity and make sure providers are responsible for their services.
