Singapore’s MRT Circle Line was hit by a spate of mysterious disruptions in recent months, causing much confusion and distress to thousands of commuters. Like most of my colleagues, I take a train on the Circle Line to my office at one-north every morning. So on November 5, when my team was given the chance to investigate the cause, I volunteered without hesitation.

A dive into Python’s asyncio tasks and event loops. The asyncio package allows us to define coroutines. These are code blocks that have the ability of yielding execution to other blocks. They run inside an event loop which iterates through the scheduled tasks and executes them one by one. A task switch occurs when it reaches an await statement or when the current task completes.

Fun article by Florin Badita using BigQuery over entire github hosted Python project's code base.

We are going to explore two parts of using a ML model in production. How to export a model and have a simple self-sufficient file for it ? How to build a simple python server (using flask) to serve it with TF ?.

What does the future hold for Python, aside from new versions of the language ?

ChatBot is the new buzz word for a while. Microsoft Cognitive Services API allows you to built ones that allow your app to process natural language and learn how to recognize what users want.

I created a semi-practical application that reads from the Twitter stream, parses tweets, and does some machine learning magic to score the tweet’s sentiment and project it into a two-dimensional grid, where tweets with similar content will appear closer to each other. It does all of this more or less in real time using asynchronous messaging.

As I’m preparing for a project that will involve Python programming, I need to get up to speed with at least a basic level of Python mastery. However, I’m not a big fan of using the interactive Python REPL. I decided to use Xcode instead, and I’m finding it a much better solution for my needs:

Introductory article on usage of pickle module.

In a recent project, we decided to use Lambda to execute some fairly math-y Python code in response to user click events on a webpage. Originally this back-end Python code had utilized the Numba library to speed up its execution. However, we quickly found that it was not trivial to make Lambda and Numba play nicely together.

From time to time I like to read documentation of modules I think I know well. The python documentation is not a pleasant read but sometimes you strike a gem.

FuzzyWuzzy is a fantastic Python package which uses a distance matching algorithm to calculate proximity measures between string entries.

In this short screencast I’ll walk you through a simple code example that demonstrates how you can use custom exception classes in your Python code to make it easier to understand, easier to debug, and more maintainable.
