Let’s run through a simple “hello world” example to create and run a simple smart contract on Ethereum. It is amazing how much a simple example can teach you.

Thoughts on dealing with burnout in tech
Mental Health with Kelsey Hightower on the always amazing Software Engineering Daily podcast – https://softwareengineeringdaily.com/2022/02/25/mental-health-with-kelsey-hightower/
This was a great podcast, and I want to thank Kelsey and Jeff for doing this talk. Burnout is a topic we do not talk about openly in the tech community; at least that is my experience over the years. I wish Jeff the very best as he navigates this. In this blog, I share some thoughts about one mental health condition that some of us face – burnout at work. My thoughts here are tied to the software engineering occupation, but it might resonate with other fields too.
GraphQL with Netflix dgs-framework
Starting the year with some back-to-basics hands-on coding using small building blocks in areas that I randomly get interested in. This time using the Netflix DGS GraphQL framework. DGS (Domain Graph Service) is a GraphQL server framework for Spring Boot.
Spring Boot and Redis PubSub
A simple Spring Boot sample to publish a message to a Redis queue, with a message subscriber that consumes the message Spring Data. See README in Github for how to set up a local Redis and run the code.
Spring Boot and Redis
A simple Spring Boot sample to save and retrieve an object from Redis using Spring Data. See README in Github for how to setup a local Redis and run the code.
Technical Debt
For a brief, but an enlightening article on Technical Debt (TD), do read this post from Martin Fowler Technical Debt. My focus here is not about what TD is, but rather some thoughts on WHEN in time do you incur it. Knowing that can help you go in with eyes wide open and maybe reduce the debt burden a bit. To assume you will not gain TD means you are either just out of school with no real-world experience or plain naive (no offense to anyone).
Say hello to Micronaut inside Kubernetes (with Prometheus & Grafana)
In the age of Serverless & Container architectures, there is once again chatter about Java being too fat (and dying). While I can understand the “too fat” observation, I will not put my money on the “java is dying/dead” chatter. That obituary has been written multiple times and the language lives on. It is true that Java was not born in the Container/Cloud era. Yes, it was born in a different age and time, but the language and framework ecosystem has evolved. In the Microservices cloud-native app world where horizontal scaling and fast startup times are expected, Java may (at times depending on the architecture) not be the fastest horse in town.
Engineering Management
It has been a few years now since I moved into the role of Software Engineering Management. While there may be various reasons for one to move to this role, it is a change that comes with very little training and no guidebook. In this blog, I will go over a few areas that I felt are areas to keep an eye on when in this role (a lot of it is relevant to non-manager lead roles too).
Take2 — Setting up k8s Cluster with k3s on Raspberry Pi 3 & Pi 4
Back to a teach-myself-something type of project, with setting up K8s Cluster on Raspberry Pi devices. I had a couple of older Raspberry Pi 3s and a recently purchased Pi 4 available for this. My old Pi3 devices had Docker Swarm (yes that one) from a couple of years back. This time around I want to get k8s on the 3 Pi devices.
The steps are fairly simple but it can be a bit of work. You should find blogs out there with decent enough directions. So here goes me adding to that library of blogs to make it easier for the next person trying to set this up.
This is an upgrade from my previous similar blog installing Docker Swarm on a two node Pi-3 cluster https://54.210.73.122/running-docker-swarm-raspberry-pi-3/
Get started with AWS SAM
I am going to point you to a few resources to help you standup a hello world serverless app using AWS Lambda using AWS Serverless Application Model (SAM).
