(Or learn anything, for that matter)


🖥 Why learn to code?

Learning to code is a really valuable skill. You can use it to build things that impact the world. And it’s a desirable skill in the current job market.

But it’s not easy. It takes a long time to learn.

Using the YouTube API and Amazon’s AWS Lambda

🚀 Escaping the YouTube algorithm

I love watching YouTube videos that improve my life in some tangible way. Unfortunately, the YouTube algorithm doesn’t agree. It likes to feed me clickbait and other garbage.

Why our AI needs to understand causality

Data Science in the Real World

And why the healthcare AI space needs more doctors

We are seeing increasing use of, and discussion about, artificial intelligence (AI) and machine learning (ML) across all sectors; healthcare included. Greater volumes of data, improved computing power and break-throughs in machine learning techniques have provided fertile soils for innovation. …

I read an article a few months ago about how Jeff Bezos banned PowerPoints from meetings at Amazon. Instead, people write a “narratively structured six-page memo” to lay out what’s being discussed.

At the time of reading the article, I was creating a PowerPoint presentation for a group of medical…

About 3 years ago, I developed a deep interest in learning to rap well. I emphasize the word ‘developed’ because up until this point, I was waiting to passively discover a passion which would somehow carry me towards expertise.
