ruby - Use DateTime to print name of day from a date? -


I am trying to use date time to go through a list of dates, and weekdays (Monday, Tuesday, Wednesday, & Amp; c) which are often associated with each date in the list.

I'm trying this: 

  content = CSV.open 'event_attendees.csv', header: true, header_converter :: icon content. Line | Time = content.map {| Line | Line [: regdate]} target_days = hash [times.group_by {| T | DateTimeTermMem (T, '% M /% D /% Y% H:% M') Wday} .map {| K, V [K, v.count]} Sort_by {| K, v | V} .reverse] puts target_days   
 I get:  
  {1 = 6; 2 = & gt; 5, 5 = & gt; 4, 6 = & gt; 2, 0 = & gt; 1}   
 What do I think that every day is 0 (Sunday), 1 (Monday) & amp; How can I change this day as a real name? Or how can this short name (Sun, Mon, Mars, and C.) be changed?  
 Besides, I am not positive, I am returning the right day on the day. Looking at my list, there are six dates for 11/12/2008 November 12, 2008 was a Wednesday ???? But it seems like it is showing that the biggest day of 6 days is Monday. So, I'm not sure that it's really counting the right day of the week.  
 Can someone please explain what I am doing, do not count the exact day of week? How to change it in the form of day and short name?  
 Thank you!   
 
 
 You  wday  integer  date :: DAYNAMES  Can be converted into full names and can change the abbreviation by using  date :: ABBR_DAYNAMES :    date :: DAYNAMES [3] # = & Gt; "Wednesday" Date: ABBR_DAYNAMES [3] # = & gt; As far as your algorithm goes, it looks right to me:  
    code> requires "date" bar = ["4/25/2014 00:00 ", # Friday" 4/21/2014 00:00 ", # Monday" 4/22/2014 00:00 ", # Tuesday" 4/20/2014 00:00 ", # Sunday" 4/22 / 2014 00:00 ", # Tuesday" 4/21/2014 00:00 ", # Monday" 4/21/2014 00:00 ", # Monday" 4/19/2014 00:00 "] # Saturday Target_day = Hash [times.group_by | Time | DateTime.STRUTMENT (time, "% m /% d /% Y% H:% M") Wday end.map do | Key, value | [Date: ABBR_DAYNAMES [Key], Value. Data] end.sort_by | Key, value | Value end.reverse] puts_s # target_days = & gt; = "Gtc: P> I will double check the content of the file, and then take action through the algorithm to see the mistake.

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...
