• RAILS: bundler does not install the package. (bundle install package)

  - by Joern Akkermann

  I started using bundler (which is to my eyes a pure desaster). Now I want to add the Googlebase-gem to my app. So I entered "bundler install googlebase" in the root of my app. Bundler in fact installs several gems, but not Googlebase. What have I done wrong?

• How to change a Window Owner using its handle

  - by Ricky AH

  I want to make a .NET Form as a TopMost Form for another external App (not .NET related, pure Win32) so it stays above that Win32App, but not the rest of the apps running. I Have the handle of the Win32App (provided by the Win32App itself), and I've tried Win32 SetParent() function, via P/Invoke in C#, but then my .NET Form gets confined into the Win32App and that's not what I want.

• Is it possible ot mix named pipe with select in perl

  - by Haiyuan Zhang

  I need to write a daemon that supposed to have one TCP socket and one named pipe. Usually if I need to implement a multi IO server with "pure" sockets, the select based multi-IO model is always the one I will choose. so does anyone of you have ever used named pipe in select or you can just tell me it is impossible. thanks in advance.

• Why is giving a fixed width to a label an accepted behavior?

  - by kemp

  There are a lot of questions about formatting forms so that labels align, and almost all the answers which suggest a pure CSS solution (as opposed to using a table) provide a fixed width to the label element. But isn't this mixing content and presentation? In order to choose the right width you basically have to see how big your longest label is and try a pixel width value until "it fits". This means that if you change your labels you also have to change your CSS.

• Did Java invent interfaces?

  - by Jordão

  I know about C++ pure virtual classes, but Java went one step further and created a first-class (no pun intended) concept for multiple-interface (not implementation) inheritance, the interface. It's now a staple of major statically-typed languages. Did Java invent the interface concept? Or did it appear in older languages also as a first-class concept?

• What is a better way to convert a simple sinatra app to static html pages?

  - by dimus

  A friend of mine asked to create a static website and I found that making such site using Sinatra is a pure joy. I just wrote all my routes like this: get '/index.html' do haml :index end get '/app.css' do sass :app end .... So I was able to use layouts, and haml and sass to put site together quickly. To create the static site I used wget -r -l2 http://localhost:4567 Which did work pretty well, but I imagine there is a better way to create a static site from a Sinatra code?

  Lets say you have an normal song with two layers, one instrumental and another of just vocals. Now lets say you also have just the instrumental layer.

• Override GWT Styling

  - by KevMo

  I had a beautiful pure HTML mockup for a webpage that I am now recreating in GWT. I'm attempting to use the same css in my GWT app, but that's not working well for me. GWT styles seem to override mine. I know I can completely disable the GWT styles, however I would prefer to have the styling for the GWT components that I'm adding (tab panel, button, etc). Is there a way to disable GWT styling, and only enable it for components that I choose?

• tapestry5 page to render plain text

  - by pstanton

  Hi All, I've been looking but can't find the the documentation: Is there a way to have a page render a response without the wrapping HTML elements and just print whatever is provided in the body of the tml or alternatively whatever is set in MarkupWriter.write during @BeginRender? I need a page that does some server side processing and returns pure javascript for an external application to request. If that is impossible, is it possible to expose the tapestry Ioc to a servlet in the same app? Thanks, p.

• What is the best approach for unit testing/integration testing GXT code?

  - by Arizonahockey

  I have been tasked to setup a continuous integration environment for a GXT 2.1.1 and GWT 2.0.1 environment. Unfortunately I am new to AJAX and Web Services and have little idea how to setup unit tests in the browser environment. Unit tests for the server backend I already have done, since I am a pro at that. GXT is not quite pure GWT which provides some unit testing structure. If anyone has a good starting point...

• decent html5 offline storage and caching examples

  - by Nils

  I'm keen to test out html offline storage and caching with a view to developing a prototype to show off the offline web application capabilities of html5. I've found some webkit-specific samples, but I'm battling to find any decent code samples that even work at all in Firefox 3.6 For a sample, I'd be happy with something that works with the following: Our company uses jquery extensively so I'd prefer samples that use that library or pure javascript. It should at least work on firefox (3.6+ is fine) Can anyone point me to some links that provide some guidance and code samples?

• is there a comprehensive example or tutorial for ibatis 3 with annotations?

  - by nn2010

  I am specifically interested in moving away from XML-based mapper configuration to using pure Java annotations where the SQL statements often take or return complex data structures. Also, it wasn't clear in the samples I saw, how the configuration file was adapted when moving away from XML-based mappers to annotation-based Mapper interfaces.

• Are EntityFramework generated Entity Persistence Ignorance

  - by pdiddy

  So I'm starting to look into EF and POCO. From my understanding, the entity generated by EF is not pure POCO since it inherit from EntityObject. But are they PI? It seem to me that they don't have any persistence awareness in them, or there is something in the EntityObject that makes them PI?

• Why Emacs/Vim/Textmate? Isn't Xcode good enough?

  - by ivanTheTerrible

  Hi I mostly do C++, Objective-C programming. And I found Xcode plus an auto completion/macro plugin (Completion Dictionary) quite adequate. However, all people seem to praise over their pure text editors. I tried Textmate for a bit; liked its simplicity but dislike its files/framework handling. Am I missing something here? Or, do Vim or Emacs have auto-completion as good as Xcode?
