Sometimes you just want to copy and paste between the host machine and a UTM console.

Struggling to copy and paste from your host machine to a UTM terminal window? You’re not alone, it’s trickier than it sounds! In this short blog post, I will show you how to add a serial console to your UTM VM instance, enabling copy and paste.

Trustless software development and reproducible builds are at the heart of Bitcoin’s ethos, and Guix is the key to making this a reality.

Setting up a reproducible Bitcoin Core build environment using Guix on a Mac can be a hassle due to its dependency on a Linux base. In this blog series, I’ll show you a simple solution: running Guix on a NixOS (within a virtual machine). This article will show how to use my NixOS flake to set up a NixOS environment for Guix reproducible builds.

Setting up a reproducible Bitcoin Core build environment using Guix on a Mac can be a hassle due to its dependency on a Linux base. In this blog, I’ll show you a simple (partial) solution: Setup a UTM to host a VM on which NixOS can be run.
