• Can I customize the Magento app/code/core folder without affecting future upgrades?

  - by mck89

  I found a guide on how to add new attributes to users, it explains that for this operation I must modify some files in the app / code / core / Mage directory (the directory that contains Magento’s modules).

• Does a simple delphi form app needs any libraries or dependencies to deploy?

  - by peterg

  I need to code a simple form application and I want to make it easy to deploy (without installing libraries or dependencies), I don't want to use visual studio cpp or csharp because clr apps compile with .net frameworks and I have no much experience with mfc and dialogs. So I was wondering which libraries does a simple delphi vcl forms app (those using TForm) use, because I've never had to install anything to run simple delphi apps.

  - by Jack Griffiths

  Hi there, Is there a way to change the name that displays on the AppStore, rather than the name associated with the credit card/apple ID associated with the developer programme? For example, if my name on my credit card was foo, and the name on the apple ID was foo, but I actually want the name displayed on the AppStore (i.e. next to my App's name and details) to be bar. BTW: The programme is individual. Many thanks, Jack

• J2SE Client Server App: Client calls RMI method. Server handles RMI method and returns, but Client

  - by Mike

  J2SE Client Server App: Client calls RMI message. Server handles RMI method and returns, but Client never receives it. Any ideas how this could happen? Our attempted solution is to set client read timeouts and come up with a framework for resending requests or otherwise handling those failures gracefully. But really, I'd like to know any root causes for how this might happen rather than addressing the symptoms.

• What is the difference between a site and an app in Django?

  - by larf311

  I know a site can have many apps but all the examples I see have the site called "mysite". I figured the site would be the name of your site, like StackOverflow for example. Would you do that and then have apps like "authentication", "questions", and "search"? Or would you really just have a site called mysite with one app called StackOverflow?

• Options and best practices to release free and paid version of the same app to Android Market

  - by Rich

  I have installed a couple of free apps on my Android phone and then later "upgraded" to the paid full version. My first instincts for doing the same would be to create two apps with the same package name so that installing one overwrites the other, but apps in the Market must be unique by package name. What are some patterns and best practices for sharing code and resources for free and paid versions of the same app and any naming conventions or project structures that work for this scenario as well?

• Localized Android app without using "res" folder. Is there a downside?

  - by user312916

  I am developing a game with Unity 3D and want to use custom code to get strings in the various languages I will be supporting. I've read articles about using the Android "res/values-xx/" directories (such as this page: http://developer.android.com/training/basics/supporting-devices/languages.html). If I do not store my translated strings in this way is there a downside? My main concern is whether the Google Play store may not know what languages my app is localized for.
