Notify Sentry of a new release via Capistrano
View deploy.rb
# This task will notify Sentry via their API[1] that you have deployed
# a new release. It uses the release timestamp as the `version`
# (like 20151113182847) and the git ref as the optional `ref` value.
# This task requires several environment variables be set (or just
# hardcode the values in here if you like living on the edge):
# ENV['SENTRY_ORG'] : the organization for this app
# ENV['SENTRY_PROJECT'] : the project for this app

Steps to get Sentry working over SSL on the JVM

Sentry and the JVM

Unfortunately Java's built-in cacerts do not include StartCom SSL root certificates.

Because of this, you must tell java to trust these certificates.

The easiest way I've found to do it is as follows:

1. Make a copy of the JRE cacerts

""" return a dict of {model : [all dependent models] """
deps = collections.defaultdict(set)

for model in models:

Code Review Quality/Performance Indicators
View gist:5146800

Questions to answer:

  • Is it a productivity hit?
  • What happens when only new hires are required to do code review?
  • How bad at large patches?
  • What about lack of automated tests?
  • Does a lot of back and forth (e.g. comments) indicate problems?
  • Does assigning more people (or less) to reviews improve anything?
  • How does a person spending more time committing (vs reviewing) affect the team?

New Sentry Buffers
View gist:5078280
When an update comes into the system we fire off something like the following:
>>> app.buffer.incr(
>>> Group, # model class,
>>> {'times_seen': 1}, # counters
>>> {'id':}, # filter restrictions, sometimes a composite key
>>> {'last_seen': now}, # metadata to update when buffer is processed
>>> )
This would get stored in a hash key as following:
>>> import cramermath
>>> cramermath.log(10)

Refined Heap Queue for Python (including capped and max heap implementation)
import heapq
from threading import Lock
class HeapQueue(object):
def __init__(self, values=None, maxsize=None, reversed=False):
Create a new heap queue.
- ``maxsize`` will create a capped queue.

Checkout github pull requests locally

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 =

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:

You can’t perform that action at this time.
