DBIx::RetryConnection to add DBI connection retry logic
Typical usage:
use DBIx::RetryConnection qw(Pg);
or:
use DBIx::RetryConnection Pg => { ... }; # options for Type::Tiny::Retry
DBI->connect('dbi:Pg:...', $user, $pass, { private_dbix_retry_connection_delay_exp => [...] });

logstash queries graphed with graphite.

Operation: Decouple whisper from graphite.

Method: Create a graphite function that does a date histogram facet query against elasticsearch for a given query string for the time period viewed in the current graph.

Reason: graphite has some awesome math functions. Wouldn't it be cool if we could use those on logstash results?

The screenshot below is using logstash to watch the twitter stream of keywords "iphone" "apple" and "samsung" - then I graph them each, so we get an idea of popularity. As a bonus, I also do a movingAverage() on the iphone curve to show you why this is awesome.

Postgis GeoJSON silent massive loss of precision with coordinates specified as string values
This works as expected:
corp=> SELECT ST_AsText(ST_GeomFromGeoJSON('{"type":"Point","coordinates":[-48.23456,20.12345]}')) As wkt;
wkt
---------------------------
POINT(-48.23456 20.12345)
but this doesn't:
corp=> SELECT ST_AsText(ST_GeomFromGeoJSON('{"type":"Point","coordinates":["-48.23456","20.12345"]}')) As wkt;

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
