Introduction

If you've ever tried to understand what's happening in an Ethereum transaction, you've probably looked at prestate traces hoping they'd reveal all. And you've probably been disappointed.

The traces show that storage changed, but not what it means. The good news: there's a tracer that can help us peer behind the curtain.

Let's look at a random ERC20 transfer I picked from mainnet:

{ "txHash": "0x9b676960821b83ca82efde55eadabb7ede3897970735b4ea5d97530da58eb53e", "result": {

Today we’re happy to be releasing System Manager 1.0!

A while ago we had a project packaged with Nix. Ubuntu was the target environment. What if we could retain the properties we learned to enjoy with NixOS, even write a subset NixOS-compatible modules, and apply them to Ubuntu? That’s when System Manager was born.

Unlike Ansible, Chef or Puppet, System Manager has the packaging and configuration managed in Nix. That means that the majority of the configuration and build errors are discovered

Let’s explore how you configure a nix flake to handle installing C++ developer libraries automatically.

Médecins Sans Frontières (MSF), also known as Doctors without Borders, was faced with a problem: They had dozens of servers deployed throughout the world, often in makeshift clinics in some of the harshest, most remote places. They needed a way to manage these servers and keep them updated ...

This custom remote cache can help speed up your CI/CD pipeline and make deployments easier. In this post I'll walk you through the steps to create a binary cache stored in an S3-compatible object storage provider. I'll show you how to:

After spending a few years providing NixOS consulting, and building tooling around it, it's time to take account. How hard is it to go from zero to a deployed application running on NixOS?

This article aims to serve as a benchmark for future tooling.

We released nix-vm-test, a test framework to quickly spin up a virtual machine and run tests using a single CLI command.

"It worked on my machine!"

Most of us who've worked in IT for any length of time have heard this complaint. You develop your software, you test it exhaustively. It looks great. Then you deploy it into production and it crashes. And the blame game starts.

Why does this happen? And how can you avoid it?

The Problem

The main cause of the "it worked on my machine" syndrome is that almost no software stands alone - it depends not only on the host's operating system, but on other software that m

SrvOS is a collection of opinionated defaults for NixOS, optimized for server environments. Today we are giving this project to nix-community.

SrvOS is a collection of NixOS modules that are optimized for servers.

Today, we’re announcing the release and donation of nixos-anywhere

This new term came to mind when I wanted to describe our team and what we work on day-to-day.

A simple free tool lets you install NixOS remotely in the cloud - or anywhere else.

Time saved with Nix > time spent learning Nix: T or F?

At Numtide, we deploy NixOS to various infrastructure providers and target platforms daily. This blog post introduces NixOS Anywhere, a tool we built to make our lives easier.

A collection of Nix packages and NixOS modules for the Ethereum ecosystem.

Deploy NixOS on any cloud or bare-metal environments over SSH.

One tool to traverse and format your whole code repository.

It's time to replace the website with something that supports blog posts.

In the past year, we grew a lot, started working with more industrial customers, learned a lot of things, and built tools to support customers' workflows. What was missing was a platform where we could share and talk about those things, so here we are.

Stay tuned, and subscribe to be notified about the next posts!
