...x is to keep using userspace virtual address. Fortunately, futex has arch_futex_atomic_op_inuser() which could be used for setting a bit to user. Note there're several cases that futex helper can fail e.g a page fault or the arch that doesn't have the support. For those cases, a simplified get_user()/put_user() pair protected by a global mutex is provided as a fallback. The fallback may lead false positive that userspace may see more dirty pages.

...attempting to assign the user to the thing. To accomplish this I used a before_save method, like this: class Thing < ActiveRecord::Base belongs_to :created_by, :class_name => "User", :foreign_key => "created_by_user_id" def before_create self.created_by = get_user() end I had trouble getting the assignment to work. I initially tried simply created_by = get_user() (no ''self'') I don''t know why ''self'' made a difference in this case. Can anyone explain this to me? Thank you. -Kelly -------------- next p...

Hi, I am wondering if it's possible to authenticate users that come from specific IP differently then other users. I will be authenticating them by postgresql so something like this would be very useful: password_query = SELECT password from get_user('%username','%host') Is that possible? Can it be done any other way? Thanks, Sebastjan

Hi there, Although I'm a quite experienced R user and know my ways in C, I stumbled upon a problem I don't know how to solve. Therefore, I hope someone can provide me with the information or pointers I need in order to understand the way in which the communication between R and C occurs. I have the following C code which basicallly reflects what I want: typedef struct { float

Is there a more elegant way of writing this? def verify_user @user = User.find_by_username params[:username] if @user.nil? message = xml.error do |xm| xm.message "User does not exists: #{params[:username]}" end render :xml => message return false else true end end Thanks, Joel --
