Fortran - I do not understand variable declarations

arrays,fortran

Here is the same code, just modernized. As you can see it expects an array of reals for a,b, and c, but FORTRAN is great in that you can treat scalars like arrays pure subroutine ilocz (a,b,c,n,m) implicit none ! Arguments integer, intent(in) :: n,m real, intent(in) :: a(n,n),b(n,m) real,...

How to submit multipart/form-data with File and Text Fields using Struts2?

java,jsp,file-upload,struts2,multipartform-data

No, you shouldn't. The Apache file upload is part of Struts2. The fileUpload interceptor is already included to the defaultStack, so you don't need to reference it in the action configuration. If you want to override parameters of this interceptor then <action name="Register" class="user.action.RegisterAction"> <interceptor-ref name="defaultStack"> <param name="fileUpload.allowedTypes">text/plain</param> <param name="fileUpload.maximumSize">10240</param>...

The cause of the problem was identified by Jim Hillhouse and confirmed by Frogblast on the Apple Dev Forums thread "OpenGL Performance Drops > 50% in iOS 8 GM": setting the text property of a UITextField (or UILabel, in my case) in a view which is a subview of GLKView...

Expression result unused for UITabBarItem

ios,objective-c,xcode6,uitabbar,uitabbaritem

That code is very, very wrong. Init methods return an object. You're supposed to use it, because sometimes the init method returns a different object than the one you started with. You almost always use alloc and init together in a pair, e.g.: tabBarItem1 = [[tabBarItem alloc] initWithTitle: @"title" image:...

extracting names from a list of (name,handler) pairs

haskell,monad-transformers,state-monad

commands is polymorphic, it has a type variable, m, but commandNames :: [String] doesn't have any type variables. This means that (barring some built-in defaults) type inference won't be able to infer the type variable for commands. There are two things you can do. You can provide a type for...

Child template not being rendered in Django

python,django

Based on the code you show above, it appears that you are not rendering a response with 'ipsum.html'. Do you mean to do this instead (note the 'ipsum.html')? def index(request): return render_to_response('ipsum.html', context_instance=RequestContext(request)) Or do you perhaps need another view altogether? def ipsum(request): return render_to_response('ipsum.html', context_instance=RequestContext(request)) EDIT With regard to...

Can a powershell script output a (╯°□°）╯︵ ┻━┻ to the console?

powershell,unicode

This is a limitation of the console rather than a limitation of Powershell. If you use a different Powershell host (e.g. the Powershell ISE) then the output will appear as you expect: PS C:\> write-host "(╯°□°）╯︵ ┻━┻" (╯°□°）╯︵ ┻━┻ If you try that in the console window you actually get...

Python is replacing all _ when I only need one replaced

Why not make a list of underscores and then replace them by index. Then when you have to print out the list to the console just use ''.join(list). So maybe something like this as your remove dash function? All I'm doing is first creating a blank list of underscores the...
