Explorations - computing, research, etc.

Some examples of where i get limited by a specific programming language/framework’s syntax/particular way of doing things, and how I navigate it by trying to see if i can solve it myself based on what i know or good old internet search, (i.e. manually loo…

Some suggestions that i offered to someone else, looking for some general guidance around setting up their DevOps processes.

In what can only be described as sign of the times, one of the books I wrote, arguably, the most impactful one, Doing Math With Python is one of the works in the Anthropic Copyright Settlement.

In this blog post, I am going to desribe how we can calculate sepsis onset time using sepsis-3 criteria for the MIMIC-III patient data.

I remember the days of reading API documentation, and figuring things out and experiencing a joy having done so.

I recently downloaded MIMIC-CXR-JPG, from Google cloud storage.

In this post, we are going to discuss an implementation detail about how we can use a custom HTTP client to use the Go GitHub SDK and the https://pkg.go.dev/golang.org/x/oauth2 package.

In this post, I am going to share what I have learned about writing HTTP client middleware in Go.

I delivered a talk at the recently concluded Kiwi PyCon XI.

I delivered a talk at the recently concluded PyCon US 2022 conference.

At PyCon US 2022, Anaconda announced PyScript: Python in the Browser.

I saw a computer for the first time at school when I was 10 years old (~1995/96).

I have finally gotten around to reading (listening) “The Code Breaker: Jennifer Doudna, Gene Editing, and the Future of the Human Race” by Walter Isaacson.

Update: Please note that my usage of “Call by reference” is not correct here as pointed out by a Reddit community member here.

While working on the solutions to exercises for my soon to be published book Practical Go, I needed to implement a way to implement an option in my command line application which could be specified multiple times.

While working on the solutions to exercises for my soon to be published book Practical Go, I wanted to write a test function which would simulate a user not providing an interactive input when one was asked for.

I always get confused between “serialization” and “deserialization”.

One word that has always baffled me in the context of software/computing is “transparency”.

I delivered a talk at the recently concluded PyCon Australia conference.

In Go, there are a couple of ways to return values from a function.

The Go module path enforces certain restrictions as expected on what constitutes a valid path.

Using a file for persistent storage (and not a database - datastore/object store) sounds like an academic exercise.

Demo - Embedding a template Demo - Serving files from a directory Learn more The most exciting feature for me in the Go 1.16 release is the new “embed” package which allows you to embed a file contents as part of the Go application binary.

In my latest article for the folks at learnk8s, I write about establishing authentication between services deployed in Kubernetes.

My two recent articles, Validating Kubernetes YAML for best practice and policies and Enforcing policies and governance for Kubernetes workloads looks at the topic of enforcing policies for your Kubernetes workloads.

Introduction Gatekeeper allows a Kubernetes administrator to implement policies for ensuring compliance and best practices in their cluster.

Introduction In this post, I will share some of my learnings and explorations on plugins in Golang.

Welcome to this new blog post!

Metadata I have posted this article on dev.to where I welcome comments and discussions.

This blog is managed as a git repository and I use Hugo as the framework for managing it.

Introduction In this post, I will describe my experiments with using Cloud Custodian to perform various tasks usually falling into the bucket of compliance and sometimes convention.

A reader of my book “Doing Math with Python” wrote to me a few weeks back about a strange problem they were having.

Introduction There are two broad discussion points in this post: Managing the lifecycle of Kubernetes YAML manifests Static guarantees/best practices enforcements around Kubernetes YAML files before they are applied to a cluster Prior art and background P…

Please note this document is currently in progress.

Since around 1.5 years ago, I have been working in roles which has required to automate various things usually classified as “infrastructure and operations” work.

Introduction The docker workflow plugin enables leveraging Docker containers for CI/CD workflows in Jenkins.

Monday was just beginning to roll on as Monday does, I had managed to work out the VPN issues and had just started to do some planned work.

Introduction When implementing a solution for allowing users other than the cluster creator to access the cluster resources we are faced with two fairly old generic problems - authentication and authorization.

Repeating the same argument to Printf If we wanted to repeat the same argument to a call to fmt.Printf(), we can make use of “indexed” arguments.

Introduction This in-progress page lists some of my findings while working with Kubernetes.

Introduction I wanted a Nginx configuration which would satisfy the following requirements: Any example.com requests should be redirected to www.example.com The above should happen for http and https http://example.com should redirect directly to https://…

Welcome to this new blog post!

Some notes on PostgreSQL which you may find useful.

I was debugging a issue where we were getting truncated logs in ElasticSearch in the context of a setup as follows: Application Logs -> Fluentd (logging) -> Nginx -> ElasticSearch The original problem turned out to be on the application side, but my first…

I wanted to setup Nginx logging so that it would perform GeoIP lookup on the IPv4 address in the X-Forwarded-For header.

In this post, we will see how we can use Golang to generate Terraform configuration from a TOML specification.

docker logs by default shows the container’s stdout and stderr logs.

I love working in software.

Windows docker images can be bulky and on a server that you are deploying your application as docker images, the free disk space becomes a metric to watch out for.

Recently, I wrote two articles about using traefik as a reverse proxy.
