Stack Static Missing Library With Guix

I installed stack_static by downloading the binary from github and moving it to .local/bin. I was able to compile haskell programs, but running them failed with the error:

$ stack run
/home/rookie/projects/random/helloworld/.stack-work/install/x86_64-linux-tinfo6/48795ad824c5ab2c527b42cc08a43bf5cd587c042c536072710c2302b997bb41/9.2.5/bin …

Comic Site Migration to SQLite

Postgres was the database for my comic site but I chose to migrate to sqlite because it would:

  • be easier to back up

I'd need to set up ubuntu, but I didn't want to lose my home directory. Everything was in one partition, so I'd lose my home folder with a re-install. I didn't want this, so I moved it into another partition.

The new partition would be the size of my home …

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 …
