Mise — Simplify Your Dev Toolchain
How Mise replaces nvm, pyenv, and scattered version managers with a single config file for runtimes, tools, and environment variables
Working across large repositories that mix multiple technologies is common in modern software teams. Keeping everyone aligned on the same tool versions, environment variables, and runtimes has always been a friction point — until I started using Mise (mise-en-place).
It has since replaced several tools on my machine (goodbye nvm, reduced Homebrew usage) and become my go-to for managing development environments, both locally and in CI.
SSH Hardening: 9 Techniques That Cut 50,000 Monthly Attacks to Almost Zero
Practical SSH hardening guide with nine production-tested techniques to dramatically reduce brute-force attacks and secure your servers
Last January, I sat down to review a server’s auth logs and felt a familiar knot in my stomach.
Over 50,000 failed SSH login attempts — in a single month. Bots methodically hammering port 22 with common credentials, dictionary wordlists, and leaked password databases. Just waiting for one mistake.
That audit changed how I think about SSH security. Not as a checkbox, but as a discipline. What follows are the nine hardening techniques I’ve since applied across dozens of production servers. Not theoretical guidelines — actual configurations with real, measurable outcomes.
Using Go Modules Hosted in a Private GitLab Repository
Configure Go, GitLab CI job tokens, and .netrc to seamlessly consume private Go modules from internal GitLab repositories
When your Go project depends on an internal library living in a private GitLab repository, a plain go get will fail — GitLab doesn’t know who is asking, and Go doesn’t know the repository is private. Fortunately, a handful of configuration steps sorts everything out, both locally and in CI.
gitlab-backup: Back Up and Restore GitLab Projects from the Command Line
A CLI tool to back up and restore GitLab projects or groups, with S3 support, hooks, and concurrent exports
gitlab-backup: Back Up and Restore GitLab Projects from the Command Line
Source code: github.com/sgaunet/gitlab-backup
When you self-host GitLab or rely heavily on gitlab.com for your projects, having an independent backup strategy is essential. GitLab’s own backup mechanism works well at the instance level, but sometimes you need something more surgical: back up a single project, or an entire group, on demand, and store the result locally or in S3. That’s what gitlab-backup does.
perplexity-go: a Go library for the Perplexity API
A lightweight, idiomatic Go client for Perplexity AI — chat completions, the Search API, and a few notes from the maintainer
I’ve been maintaining perplexity-go for a while now — a small Go client for the Perplexity AI API. It started as scratching my own itch (I needed a CLI to query Perplexity from scripts) and grew into a library I now reach for whenever a Go project needs real-time, cited answers from the web.
This post is a tour of what it does, why it exists, and how to use it.
