ruby - Difference between Dir[File.join(File.dirname(__FILE__), '..', 'lib', '**/*.rb')].each { |f| require f } and $ << File.join(File -


Is there any difference between these two codes for spec_helper.rb?

Or things to do this practically? 

  $ < & Lt; File. (File. Dainam (file), '..', 'Lib') Dir [File.join (File.dirname (__ FILE__), '..', 'lib', '** / * .rb')] . Each {| F | |    
 
 
 They are not exactly the same.  
  file.join (File.dirname (FILE), '..', 'lib')  does not work right version of  file. (File. Dynamic (__ Fail__), '..', 'lib') depends on  which takes the path of the file that is in that line and he joins / (with your OS course) With  '..'  and  'lib' . So in the end you get a string (nothing) that  '/ location-of-the-file /../lib'   
 As the  File.dirname (__ FILE__), '..', 'lib', '** / * Dir.glob (see based on the input string .rb'))  (which again is what I do Describe above).  Dir [String]  Result array of all files (only one string and nothing) that match the globing string. In this case, all the files in LibreOffice Directory (including sub-dealers) that expire in  .rb  Then the code goes to each string that represents a file and has a  requirement  (loading the code in the current file).

c - Mpirun hangs when mpi send and recieve is put in a loop -

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
