We’re back from a too-long hiatus! I know you missed us.

Centralized logging had been on our backlog for quite some time at Chartbeat.  After taking care of some yaks to be shaved, we got to implementing Logstash about a year ago.  We by no means have the largest cluster, averaging around 25k events/sec and peaking at 50k during backfills.  We’ll share some tips from what […] Keep reading

Bend PostgreSQL to Your Pythonic Will

March 9th, 2015 by Wes

Back in 2014 I gave a presentation at PyGotham on a neat PostgreSQL feature called Foreign Data Wrappers.

The Weekliest Links, Thanks to You Humans No Longer Read Maps Edition

March 6th, 2015 by Wes

Sometimes building the better product isn’t what you need for success.

Schrodinger’s unlucky Cat can be alive! The Cat has been used to represent possible quantum states of a particle.

It is thus assigned both dead and alive states since […] Keep reading
