ruby - How to store a list of small numbers in Postgres -


i have long list of small numbers, of them < 16 there can more 10000 of them in unique list.

i values comma separated list, like:

6,12,10,2,2,2,6,12,8,2,2,6,10,2,4,12,14,10,2, .... lots , lots of numbers

and need store values in database in efficient way in order read , processed again ... string, comma separated values.

i thinking of sort of storing them in big text field ... find adding commas in there waste of space.

i wondering if there best practice scenario.

for more technical details:

for database have use postgres (and sort of beginner in field), , programming language ruby (also beginner :) )

numbers = "6,12,10,2,2,2,6,12,8,2,2,6,10,2,4,12,14,10,2"  numbers.split(',')        .map { |n| n.to_i.to_s(2).rjust(4, '0') }        .join        .to_i(2)        .to_s(36) #⇒ "57ymwcgbl1umt2a"  "57ymwcgbl1umt2a".to_i(36)                  .to_s(2)                  .tap { |e| e.prepend('0') until (e.length % 4).zero? }                  .scan(/.{4}/)                  .map { |e| e.to_i(2).to_s }                  .join(',') #⇒ "6,12,10,2,2,2,6,12,8,2,2,6,10,2,4,12,14,10,2"

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
