Julian's Notes

As I stared at the wallet balance on my Bundle app, I couldn’t help wondering what was going on. Date: May 13, 2021. My crypto portfolio had lost over 20% value in 24 hours. It was a bloodbath. From Bitcoin to Ethereum, Cardano, BNB. All were in the red. What manner of fuckery?? The crypto […]

For the past few months, I haven’t turned up any new articles. Partly due to laziness, partly because I’ve been on a journey of rediscovery. I call it rediscovery because I thought I had already trod the path of discovery. I thought I knew who I was, and who I wanted to be. But that […]

Some time ago, I found myself ruminating on a pertinent question; one I have asked myself multiple times. I’m pretty sure you might have asked yourself the same question if you’re a thinker like me.

Anyone who has followed Nigerian music over the years can acknowledge it has come a long way. Once there was a time I didn’t fancy much of the jams our artists put out. I would label them as too loud or too fast, with inordinately shitty lyrics. But times have changed. I guess the current […]

Much of Machine Learning involves finding and exploring patterns in data. ML algorithms will typically learn patterns from training data and apply what is learned on new data. One algorithm deviates slightly from this method, however; instead choosing to discover patterns as it encounters new data. K Nearest Neighbours (KNN for short) is an algorithm […]

Throughout last week, I was unable to shake off an overarching feeling of dread. Usually, I’m not one to allow external circumstances to influence my mood. Life is hard. Shit happens. You can’t take many things to heart. But if you’re a Nigerian like me, then you probably followed the recent protests against police brutality […]

Java developers will agree that Java 8 felt like a huge paradigm shift from Java 7. Java 8 was released in March 2014, and most notably introduced functional programming concepts, lambdas, and the Streaming API. Functional Programming in Java was a huge win for a language that already had a reputation for being too imperative.  […]

About a few weeks ago, I was mindlessly scrolling twitter when I stumbled on a tweet by Vala Afshar. In the tweet, he mentioned that google came into operation in the late 90s, at a time when there were several search engines already in the market.
