Kubernetes Basics

"We've got this project on kubernetes that you'll be helping maintain"

This started my journey with kubernetes. I found a great tutorial from freecodecamp and this blog is an attempt to set up some personal projects using it. It's best to read the original though as it's more in-depth.

Sending Mail from Cron in Ubuntu 20.04 LTS

I created a cronjob to back up my server content and wanted to test out emailing of errors when they occurred. To set this up, I installed msmtp and msmtp-mta to help send emails using an smtp server and bsd-mailx to test sending emails from terminal. The cronjob entry was …

TaskLite Setup

I used vimwiki for task management, with a couple of custom snippets and scripts, but this quickly became complicated. I needed another tool that would be easy to use, easy to understand and easy to tweak. TaskLite fit these conditions perfectly:

  • It's build on haskell and sqlite, a language and …

Thinkpad T440 ArchLinux Setup

I recently got a Thinkpad T440 and decided to document the steps I took to set up archlinux. The last time I'd done this was on the Asus Zenbook UX330UA some years back. I thought the process would be different, but it was largely similar.

I first got the iso …

First Haskell Parser (for Kindle Highlights)

Kindle saves highlights, bookmarks and notes in a My Clippings.txt file. I needed a way to parse it and filter out the content I wanted. I also wanted to work on a parser in haskell, so this was a great opportunity to get my hands dirty.

I used stack …

Python Timeit with Partial

The timeit module provides an easy way to time python code. I use it to check if a new code implementation runs faster than an older implementation.

Example usage of this is:

import timeit


def greet():
    print('Hello World')

timeit.timeit(greet, number=4)

Timeit …

Working With A Bad Codebase

I've worked with codebases that have made me frustrated. Some of the **features** I've seen include:

  • Naming the variables returned by a function $this and $return.
  • Having different languages in the same project. For example, I got one which had PHP, Python, Perl, JavaScript (node in the backend) and c …

Vimwiki Website Deployment using Git Hooks

I use vimwiki to keep a track of my notes. This includes book summaries, linux commands, recipes and miscellanous content. It's an amazing vim plugin that provides easy access and navigation to the content. This however works well only within vim.

I occasionally need to access these notes outside vim …

Huion 420 driver setup

I bought the Huion 420 because I wanted to experiment with graphics tablet and drawing on linux. I chose this primarily because of its cost. Out of the box, the device worked on my archlinux setup, however it behaved more like a mouse, with pressure sensitivity not detected. I did …
