Create ObjectIds in PostGres following the MongoDB semantics. Very similar to the Instagram approach linked below. http://docs.mongodb.org/manual/reference/object-id/ http://instagram-engineering.tumblr.com/post/10853187575/sharding-ids-at-instagram
CREATE OR REPLACE FUNCTION generate_object_id() RETURNS varchar AS $$
DECLARE
time_component bigint;
machine_id int := FLOOR(random() * 16777215);
process_id int;
seq_id bigint := FLOOR(random() * 16777215);
result varchar:= '';
BEGIN
SELECT FLOOR(EXTRACT(EPOCH FROM clock_timestamp())) INTO time_component;
SELECT pg_backend_pid() INTO process_id;

Created May 27, 2016 05:11 — forked from rafecolton/Golang-binary-versioning.md
Copypasta for easy versioning for your Go binaries

Golang Binary Versioning Trick

To use, place the code in version_trick.go in your project. Don't forget to change the namespace to match yours to the actual name of your package.

In addition to version_trick.go, there's a makefile-snippet, that includes the secret sauce for making this trick work. Be sure to change the package name there as well.

Enjoy!

P.S. Special thanks to @meatballhat by way of @syscomet for showing me this trick!

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.
