• All permissions with declarative_authorization

  - by pablorc

  Hi, I have a Rails application using Restful authentication and declarative authorization. I have some roles with an admin. Is there any method to have automatically granted all permissions to this role, instead of hardcode every controller in the authorization_rules? Something like: role :admin do has_permission_on :everything, :to => :manage end Or a uglier approach with introspection, maybe? Thanks in advance

• How to get the time on the point that you click on the clock?

  - by Jeff

  For instance, when you click the clock on the screen, there will pop up a notification/dialog which displays the exact time point. Anyone can tell me how to achieve this function? Thanks in advance! Maybe I should explain the "exact time point" . For example, there is a big analog clock on the screen. When you click around the dial, it will pop up a dialog box to display the exact time.

• Force Tab Activity creation?

  - by Daniel

  I have a TabHost and several tabs added to it. Problem: The activities on these tabs are not created until the tab is pressed. My tabhost is broadcasting intents but my broadcast receivers are not registered until onCreate in my tab activities is called. Is there any way to force activity creation? Maybe my tabhost can call setCurrentTab and switch back to main tab(0), but is that really the best option available?

• Good C++ Debugging/IDE Environment for Linux?

  - by Brandon Pelfrey

  I have a friend who is trying to make the switch to Linux, but is hung up on the apparent lack of debugging/IDE environments for C++, especially as they relate to template programming. He has been using visual studio for years and is maybe a little spoiled by their awesome IDE. Does anyone have any good suggestions for an environment where he can, under Linux, develop and debug with all of the usual things (Breakpoints, line highlighting for compilation errors, step in/over/out/etc, etc) that he's accustomed to? Thanks!

• What's the easy way to test for 304 reponses?

  - by John Mee

  I need to test if my 304 responses are working, but my development environment is pretty hard set on force no-cache. Is there an easy way to modify the max-age value of the cache-control header before it goes out? I'm perhaps a bit optimistic in hoping chrome (or an extension, or FF) has a console command letting me alter the if-modified-since header then send the request. Maybe paste something into a telnet connection?

• How to make a macro which gives back a string into the source code?

  - by mystify

  Example: I want to do this: METHODNAME(5) { // do something } which results in: - (void)animationStep5 { // do something } Is there any way to do this? Basically, what I need is a way to generate a real source code string before the program is compiled, so the compiler does see - (void)animationStep5... Or maybe there's something different than a macro, which can help here to auto-generate method names (not at run-time)?
