match, text, number = *"foobar 123".match(/([A-z]*) ([0-9]*)/) I know this is doing some kind of regular expression match but what role does the splat play here and is there a way to do this without the splat so it's less confusing? ...

My server is using a TCPServer and I'm attempting to use TCPServer::recv(), but it doesn't wait for data, so just continues in a tight loop until data is received.

Hi, Disclaimer: I'm not a programmer, never was, never learned algorithms, CS, etc. Just have to work with it. My question is: I need to split a huge (over 4 GB) CSV file into smaller ones (then process it with require 'win32ole') based on the first field. In awk it's rather easy: awk -F ',' '{myfile=$1 ; print $0 >> (myfile".csv")}' ...

fruit = ["apple","red","banana","yellow"] => ["apple", "red", "banana", "yellow"] Hash[*fruit] => {"apple"=>"red", "banana"=>"yellow"} Why does the splat cause the array to be so neatly parsed into the Hash?
