Linux Desktop on Apple Silicon in Practice

NOTE: Time flies, and it's been almost five years(!) since I wrote this. Beaware the text below is now outdated (e.g., now Asahi Linux has graphics acceleration even better than this). The commands listed are up-to-date.

I bought M1 MacBook Air. It is the fastest computer I have, and I have been a GNOME/GNU/Linux user for long time. It is obvious conclusion that I need practical Linux desktop environment on Apple Silicon.

A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

It's 2024. You should use tsup instead of this.

Features

🔥 Blazing fast builds
😇 CommonJS bundle
🌲 .mjs bundle
✨ .d.ts bundle + type-checking

Set up Theia IDE on Raspberry Pi 4

Requirements

Install node version 10 and yarn:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.5/install.sh | bash
nvm install 10
npm install -g yarn

Tunneling Ethernet Over SSH With Socat and Tap Devices

There are circumstances where one wants to attach the local machine to the same layer 2 ethernet segment, which a remote machine is connected to, with the only available transport being SSH.

While this solution has quite some shortcomings and should not be used to replace a real VPN, it can be beneficial e.g. for debugging network issues remotely.

	#!/usr/bin/env bash
	# set -x
	Git_status=$(curl --silent -H "Accept: application/vnd.github.v3+json" "https://api.github.com/repos/umlaeute/v4l2loopback/tags" )
	TAR_dl=$( echo "${Git_status}" \| jq -r ".[].tarball_url" \| head -n1)
	TAR_v=$( echo "${Git_status}" \| jq -r ".[].name" \| head -n1)


	build_dir="${build_dir:-/usr/src/v4l2loopback-"${TAR_v}"}"
	tmp_dir="${tmp_dir:-/tmp}"
	mokutil_out_dir="${mokutil_out_dir:-/root/.ssh/mokutil-module-signing}"

	// Example below is with mitm6 (https://github.com/fox-it/mitm6/)

	// Note: Adding the '--add-binary' option here is specific to mitm6, not required in all cases.

	# pip install pyinstaller
	# pyinstaller --clean -F --add-binary="/usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0:." ./mitm6.py

	// The step above will create a single binary in the ./dist/ directory called mitm6

	// Install staticx and dependencies

	// Package gochannels example of how to close a channel written by several goroutines
	package gochannels

	import (
	"math/big"
	"sync"
	)

	// Publisher write sequences of big.Int into a channel
	type Publisher struct {

	#!/bin/sh
	#
	# This script installs a virtual desktop using Xvfb, x11vnc, mate-desktop,
	# mate-session-manager and Apache Guacamole. It runs on Alpine Linux Edge.
	#
	# See also:
	# https://www.reddit.com/r/selfhosted/comments/b6k8go/poc_a_desktop_in_a_container_on_a_server/

	# This is the user, under which the MATE desktop will run
	# Notice: For several reasons this shouldn't be root

	package main

	import (
	"fmt"

	"net"
	"sync"
	"time"
	_ "unsafe"
	)
