Product managers

Seek out failure, it teaches us to think like a scientist. If you start with a hypothesis, then try to prove yourself wrong, you’re bound to make much better decisions. You have to be willing to fail, and that in itself is going to help you build confidence and be more convicted about what your strategy is in the end.
There are hundreds of methods for building products and running teams. As a quality PM, it's important to have an open mind about all of it, but finding your own process and philosophy can be grounding. It helps you find your pillars so that you don't smash into things while you're building. Remember, however, that you can always find a budget for remodeling. 😉
The beauty of a good process is when it just becomes how you do your work. When you forget you're following a process at all is when you know the process is working for you, your team, your company, and your customers.
The advice I give new Product Managers or PMs coming onto a team for the first

Finding a Ruby memory leak using a time analysis

When developing a program in Ruby, you may sometimes encounter a memory leak. For a while now, Ruby has a facility to gather information about what objects are laying around: ObjectSpace.

There are several approaches one can take to debug a leak. This discusses a time-based approach, where a full memory dump is generated every, say, 5 minutes, during a time that the memory leak is showing up. Afterwards, one can look at all the objects, and find out which ones are staying around, causing the

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

When should you use DateTime and when should you use Time?

It's a common misconception that [William Shakespeare][1] and [Miguel de Cervantes][2] died on the same day in history - so much so that UNESCO named April 23 as [World Book Day because of this fact][3]. However because England hadn't yet adopted [Gregorian Calendar Reform][4] (and wouldn't until [1752][5]) their deaths are actually 10 days apart. Since Ruby's Time class implements a [proleptic Gregorian calendar][6] and has no concept of calendar reform then there's no way to express this. This is where DateTime steps in:

>> shakespeare = DateTime.iso8601('1616-04-23', Date::ENGLAND)
=> Tue, 23 Apr 1616 00:00:00 +0000
>> cervantes = DateTime.iso8601('1616-04-23', Date::ITALY)
=> Sat, 23 Apr 1616 00:00:00 +0000
