This is an entry level tutorial for programmers (such as myself) new to Data Science and Machine Learning. It introduces people to Kaggle competitions, Jupyter Notebooks in Python, as well as the Pandas and NumPy libraries.

I show how, without any statistics, Data Science or Machine Learning, we are able to place in the top third of Kaggle’s Titanic competition leaderboard.

0. Prerequisites — Anaconda, Jupyter Notebooks

We’ll need some basic knowledge of programming (variables, basic Python syntax). The easiest way to install what you need is by heading to Anaconda and download the Python 3.7 GUI installer bundle. …

When Apple announced their iMac with 5K display I was hypnotised — it was the best looking desktop computer that I had ever seen. The Mac of my dreams.

Little did I know that it was going to be one of the WORST investments I made in the past 4 years.

This is a story about a computer. But it’s actually a lesson.

Until late 2014 I’d spent my days coding on, alternatively, a 2009 15 inch MacBook Pro or a tiny 11 inch Mac Book Air from 2013. Both of them were decent machines for writing code, but terrible whenever design…

He had looked so tired that last time I had seen him, 4 years ago. His characteristic joy and “make it look easy” attitude had been swept away by responsibilities; deep bags under the eyes, stress and lack of sleep showing in.

For the past 9 years I’ve developed, released and managed over 100 apps for iPhone, iPad and Mac and around 1000 updates for them. I’ve read thousands of articles with tips and tricks on cheap app marketing tricks for that an indie developer could use. I’ll share some of the lessons I learned. Don’t run away — there’s useful information for anyone here — you might not be into mobile entrepreneurship, but you’ll probably want to sell something online at some point(even if only on Craigslist or Ebay).

Let’s play pretend: you’ve just spent a fortune developing a cool new…

[This is a repost from my HackTheDay blog of 6 years ago. But these are rare-to-find tips that are still highly valuable.]

You don’t really need a reason to try out these Mac OSX tips and hacks. But they are fun, probably useful and definitely will get a nice reaction from your friends.
