Makefile fragment that generates makefile targets to call make with a given target on all apps/* subdirs. Useful for erlang projects using erlang.mk that have apps/{app1,app2,app3..} structure (which rebar doesn't mind). Eg: call "make app" and it will call "make -C apps/app1 app; make -C apps/app2 app; ..." for you.
APPDIRS := $(wildcard apps/*)
## Example hack to filter one out:
## APPDIRS := $(filter-out apps/fooapp, $(APPDIRS))
define PROXY_TARGET
$(1):
$(foreach appdir,$(APPDIRS),$(MAKE) -C $(appdir) $(1) ;)

Encouraged by a tweet by Alice Maz (https://twitter.com/alicemazzy/status/623774654772170752), here's my Erlang version of "how to crack a simple crypt" exercise.
-module(magic).
-export([crack/1]).
crack(BaseH) ->
Base = hex_string_to_bytes(BaseH),
Scores = lists:sort([ {score(Base, I), I} || I <- lists:seq(0, 255) ]),
{_, Best_Key} = lists:last(Scores),
<< <<(C bxor Best_Key)>> || C <- Base >>.

Load environment variables from dotenv / .env file in Bash
if [ ! -f .env ]
then
export $(cat .env | xargs)
