How To Interview Engineers

Interviewing is hard. It's not easy to find good people, and once you do, it's often difficult to find out what they can do and how they work. A badly-run interview can pass over a great engineer. Conversely, some engineers are good at passing traditional tech interviews, but bring major problems with work habits or team fit.

The first priority of any manager is to hire the best people. Everything else must wait.

• UTC is best practice http://stackoverflow.com/questions/2532729/daylight-saving-time-and-time-zone-best-practices
• DST changes can causes issues with things like opening hours, publication dates on contracts, etc... UTC helps avoid this
• embrace the pattern: UTC on systems and APIs, TZ display in UI/UX and outputs
• integrations with partners, 3rd-party services (think Amazon, Google Cloud computing, pub/sub services, filepicker... all will use UTC)
• you trade "easier to think about" for "subtle bugs and weird test fails" in the future
• people assuming we're standard UTC like the rest of the world might set up servers/services in CEST and be off by an hour (past example: localina!)
• someday you will work for a company that does things outside of Switzerland. You should learn this :)

Thoughts about Rails Presenters

This is a collection of links, examples and rants about Presenters/Decorators in Rails.

---

The "Decorator" pattern slowly started gaining popularity in Rails several years ago. It is not part of core Rails, and there's many different interpretations about how it should work in practice.

Jay Fields wrote about it in 2007 (before he switched back to Java and then Clojure): http://blog.jayfields.com/2007/03/rails-presenter-pattern.html

#!/usr/bin/env ruby
require 'rubygems'
require 'raindrops'
require 'statsd'

#
#  This script monitors the active and queued unicorn processes.
#  It uses the raindrops gem to look at the unix domain socket.
#  Stats are polled every second (for one minute) and pushed to
#  statsd as a counter. This script runs once a minute.

#!/usr/bin/env ruby
require 'socket'

# This script runs every minute, captures stats about redis
# and forwards them to graphite as counter values.
