• Features to remove from C++

  - by Justin Ethier

  This question was inspired by What features would you like to see added to C++? (also see What features do you miss in C++?). C++ is a great general-purpose language, but perhaps too general and feature-rich: multiple inheritance, operator overloading, manual memory management, templates, smart pointers, virtual destructors, legacy frameworks (think MFC), and I could go on. Is there any one feature or aspect of C++ that you would like removed to make our lives easier as C++ developers? One feature per answer, please.

• What is the reason to use observe_field instead of onkeydown in rails?

  - by gorn

  Is there any good reason why most rails developers use observe_field when they want trigger specific action when text input box is changed, rather then using onkeydown? I would expect, that in most of the cases using observe_field results much more code generated than just using native hook onkeydown.

• Lambda Expressions for a 5th Grader

  - by Randy Minder

  If you had to explain Lambda expressions to a 5th grader, how would you do it? And what examples might you give, or resources might you point them to? I may be finding myself in the position of having to teach this to 5th grade level developers and could use some assistance. Thanks very much.

• How can I estimate server costs for creating an app?

  - by G Dottin

  Im writing up a business plan and im having some trouble with the finance part. I put an estimate on the cost of developers, web designers and everything but server costs. Im not a programmer so I dont know all the details. But how much would you think servers are going to cost for a complex app. I cant get into too many details but it keeps track of user preferences, stores data about the user and there is quite alot of back-end to it.

• When does the @ become usefull?

  - by DaNieL

  As you know, the @ characters before a php istruction suppress every eventual warning, error or notice from being raised. Personally, i dont like this tecnique, becose i prefer to handle those errors, and in a real life, the error must no happen or have to be managed. By the way, i find this tecnique to be applied in many scripts (cms plugins, open-source classes). So, could the @ really be usefull (in this case, an example would be appreciated), or is just for lazy developers?

• Localize Strings in Javascript

  - by SaaS Developer

  I'm currently using .resx files to manage my server side resources for .Net. The application that I am dealing with also allows developers to plugin javascript into various event handlers for client side validation, etc.. What is the best way for me to localize my javascript messages and strings? Ideally, I would like to store the strings in the .resx files to keep them with the rest of the localized resources. I'm open to suggestions.

• should I put the jar dependancies on the sahred repo or just the source files ?

  - by ashy_32bit

  We have a Scala project with few source files (in Scala and Java) and quite some dependencies in various binary formats (jar and DLL). I'm wondering what should go into our shared git repo. Only the source files (developers have to download or somehow resolve the dependencies themselves) or the both the source files and the dependencies? I may add that dependencies are all third parties and available for download for free.

• Frequent Functions: How to Structure?

  How should one structure their frequently used non-important functions (conversions, etc) in C# since everything must be contained in an object? Usually I take all these functions and put them in a static Utility class. Is this a good practice? How do most developers do it?

• Getting started with PHP on Windows

  - by jamesaharvey

  I'm getting started with a side project that will be developed using PHP and I'm looking for guidance on getting my Windows machine up and running and ready for development (as quickly as possible). Being that PHP development is more geared towards Linux users/developers (which I am not), I'm trying to figure out how to get all the pieces in place to get a 'WAMP' stack operational locally on my Windows machine. Any good tutorials/quick start guides out there and if not, does someone have all the steps that they could provide me with here?

  I have a ruby method (deactivate!) that is on an activeRecord class. However, I can't seem to find where that method is declared.

Any ideas how to find all the superclasses for an instace, or where to find the code for deactivate!?

• Facebook Connect: Redirect to FB login page instead of popup

  - by AyKarsi

  I'm just starting of to get Facebook connect to work. One thing that really bugs me, is that when I click the FB login button, it opens up a popup. I would much more prefer to have the user redirected to FB, where he can login and be sent back to my site. (Just like openid login works here at SO) I can't find anything in the docs, although I have the feeling I'm not looking in the right place: http://developers.facebook.com/docs/reference/javascript/fb.api/

  I know that the Apple community – including Mac and iPhone developers – mainly use Objective-C for their development language. But it seems that not many people use Objective-C outside of the Apple community, such as in the Windows or Linux worlds.
