How to have shared state between different instance of a class without a singleton pattern.

The ‘Singleton’ DP is all about ensuring that just one instance of a certain class is ever created. It has a catchy name and is thus enormously popular, but it’s NOT a good idea – it displays different sorts of problems in different object-models. What we should really WANT, typically, is to let as many instances be created as necessary, BUT all with shared state. Who cares about identity – it’s state (and behavior) we care about!

I lost an hour of my life today trying to figure out why Sphinx would not document a class inside a module specified by :automodule:.

I learnt two things today.

This might be a very esoteric topic for most people, but since I could not find information about this anywhere, I decided to document this in a post.

Here is the problem. I use Jira at work, and today, I needed to close a bunch of tickets based on a search result. Now, searching or doing batch operations is simple enough from the browser, but a small detail made the exercise impossible via the web UI.

It is impossible to ignore avro at work - it is the data serialization format of choice at work (and rightly so), whether it is to store data into Kafka or into our document database Espresso. Recently, I had the need to read avro data serialized by a Java application, and I looked into how I might use Python to read such data.

Having worked with Python for a while, I am trying to pick up Ruby, especially for some of my work with logstash. While trying out a small program in Ruby, I got stumped with a peculiar trait of Ruby hashes with default values. It made me lose an hour of my life I am not going to get back. :(
