attempt to find a easy to say domain

README.md

I wanted to find a domain that could easily be spelled without confusion.

newdomain.py

import random
import itertools

letters = "qwxfhlrs"

for item in itertools.permutations(letters, 4):
    print "{}.com".format("".join(item))

whois.erl

#!/usr/bin/env escript
%% -*- erlang -*-
%% -smp enable 
-mode(compile).

domain_available(WhoisResult) ->
    re:run(WhoisResult, "No match for") =:= nomatch.

whois(Domain) ->
    os:cmd(["whois ", Domain]).

mapper(Domain) ->
    Result = whois(Domain),
    case domain_available(Result) of
	true ->
	    {ok, Domain};
	false ->
	    nothing
    end.

read_lines(FH, Acc) ->
    case file:read_line(FH) of
	{ok, Line} ->
	    StrippedLine = string:strip(Line, right, $\n),
	    read_lines(FH, [StrippedLine|Acc]);
	eof ->
	    Acc
    end.

output([]) ->
    ok;
output([nothing|Rest]) ->
    output(Rest);
output([{ok, Domain}|Rest]) ->
    io:format("~s~n", [Domain]),
    output(Rest).


main([DomainFile]) ->
    {ok, FH} = file:open(DomainFile, [read]),
    Domains = read_lines(FH, []),
    file:close(FH),
    Results = plists:map(fun mapper/1, Domains),
    output(Results).

Took 28s to do whois queries on 1680 domains.

Where did you get your plists from? I tried it from https://code.google.com/p/plists/source/browse/#svn%2Ftrunk but I get exceptions on osx lion with R16B and ubuntu precise with r14b04.

Using regular lists:map/2 works but is predictably slow. Using plists, I get:

escript: exception exit: {emfile,[{erlang,open_port,
                             [{spawn,"/bin/sh -s unix:cmd 2>&1"},
                              [stream]]},
                     {os,start_port_srv_handle,1},
                     {os,start_port_srv_loop,0}]}
in function  plists:handle_error/3
in call from plists:local_runmany/3
in call from whois_erl__escript__1369__282284__13128:main/1
in call from escript:run/2
in call from escript:start/1
in call from init:start_it/1
in call from init:start_em/1

Ever seen that?

Found it. Just too many domains at a time. At least on my machine, it gets maxed out at 511 domains.
