Make Nerd fonts work with the Chromebook terminal

Here is a too complicated hack to make Nerd fonts work on the Chromebook terminal. There should be an easier way. Please tell me if you find it.

First we need a CORS compliant web server to fetch the font. I didn't want to have to be online to use the terminal so I'm going to run the server locally. Fetch the server.py file (below) and save it to your linux environment. I put it in ~/hacks/nerdfont/server.py. This little script adds the CORS headers to the python3 http server. It will only serve files from the current folder.

In my ~/.bashrc I added these lines:

# make the nerdfont available to the chromebook terminal

Wazuh pain points

After I started to use Wazuh, around June 2022, I came across many pain points. Here, I recorded and grouped some of them together. There is no specific order, neither alphabetical nor by importance.

Setup Nerd Fonts in Chrome OS terminal

Press Ctr + Shift + j to open devtools console in crostini terminal.

Paste this to use Jetbrais Mono with ligatures:

term_.prefs_.set('font-family', 'JetBrains Mono Nerd Font, monospace');
term_.prefs_.set('user-css-text', '@font-face {font-family: "JetBrains Mono Nerd Font"; src: url("https://raw.githubusercontent.com/ryanoasis/nerd-fonts/master/patched-fonts/JetBrainsMono/Ligatures/Regular/JetBrainsMonoNerdFont-Regular.ttf"); font-weight: normal; font-style: normal;} x-row {text-rendering: optimizeLegibility;font-variant-ligatures: normal;}')

Google Carbon Snippets

This file contains some of the basic syntax for Google Carbon as well as some info and how to get set up.

The official repo and docs can be found at: https://github.com/carbon-language/carbon-lang

Carbon is an experimental successor to C++. It is NOT ready for production and will not be for a while. This crash course and document were made to explore some of the basic syntax.

Scripts that need to be installed

To run the project, you will need to install the following programs:

Walk-through to setup Enterprise Wifi with Unifi on Windows Server

Update 14/02/2024 : Added step 3-d - allowing the cert template to be issued by a CA

Why

Quite simply, you will have the ability to log on to your Company Wifi network using your Windows Domain Username and Password. No more remembering someone else's idea of a secure password. A Single Sign-on for all resources.

Building a Secure Arch Linux Device

Locking down a linux machine is getting easier by the day. Recent advancements in systemd-boot have enabled a host of features to help users ensure that their machines have not been tampered with. This guide provides a walkthrough of how to turn on many of these features during installation, as well as reasoning for why certain features help improve security.

The steps laid out below draw on a wide variety of existing resources, and in places I'll point to them rather than attempt to regurgitate full explanations of the various security components. The most significant one, which I highly encourage everyone to read, is Rod Smith's site about secure boot, which is the most comprehensive and cogent explanation of UEFI, boot managers and boot loaders, and secure boot. Another incredibly useful resources is Safeboot, which encapsulates many of the setup steps below in a Debian application.
