Lightweight Docker images with Alpine

One of the challenges in building Docker images is keeping it small and lean. For example, let's take a simple app that prints a simple message to the console, and containerize it in Docker.

Building a service mesh with Istio

If you're looking to build a modern microservices architecture that is highly scalable, observable, secure and resilient, it would make sense to consider some of the service mesh technologies that are rapidly evolving right now. At the time of this writing, Istio is one of the key frameworks that have been gaining a lot of traction, and a key contender in the service mesh race.

AlphaGo: a journey to machine intuition

When IBM's Deep Blue beat Gary Kasparov, I was fifteen years old. I didn't know the significance of the event at the time, nor was I even interested in the epic battle that was to define the technology advancements in AI in that decade.

Dissecting Bitcoin, Part 1 — The Technology

Recently, I decided to pull up Satoshi Nakamoto's paper with the hope of getting a deeper appreciation for Bitcoin and the machinations of a protocol that's driving speculators insane watching a candlestick chart. In the paper, Satoshi puts forward a solution to an old problem in distributed computing circles using Cryptography.

For the love of chess

Nearly twenty years to this day, in May 1997, a machine that IBM built challenged then world chess champion Garry Kasparov to a six game match, and won. An year earlier, in 1996, a similar match between the IBM built Deep Blue and Garry Kasparov ended with Kasparov winning the series comfortably.

Machine learning for fun and profit

Machine learning and artificial intelligence has been going through a phase of democratization to the point that in recent years the barrier to entry for technologies that can be used to build intelligent and self learning applications is at an all time low. I will show just how easy it is to get started with machine learning by walking you through building a simple classifier using open source technologies.

Bootstrapping Go

Over the weekend, I came across a couple of videos on how the Go compiler was migrated from C to Go. The Go compiler was originally written in C and after it reached a certain level of maturity, the creators were looking at how to bootstrap the compiler in Go so that the language can inherit some of the benefits of Go.

Stop worrying, and just get things done

Two years ago, I pulled out my dusty copy of David Allen's Getting Things Done and decided to do a another skim through. Things were getting out of hand and I really needed to get my act together in managing the daily barrage of endless activity.
