Jun 6, 2020

** Note: this post addressed the boot error gbb.flags is nonzero: 0x00000489 in Chromebook.

Aug 8, 2018

Neovim Markdown Preview

Jul 7, 2018

Neovim Markdown Install I came across VIM Markdown Composer as I was looking to edit more using tmux and Neovim. Installed Rust and Cargo following instructions using the guidance from the Github page. Interestingly, this installed a lot of packages in Rust very slowly. Cargo is a package manager for Rust I think.

Gitlab Pages Custom Domain Setup

Jan 1, 2017

Mistryious.com is built using Hugo and is hosted on Gitlab Pages. It uses Gitlab CI for pushing new content and changes to the site.
