Getting a certificate installed is table stakes; configuring TLS correctly is where servers actually differ. Plenty of production sites serve valid HTTPS and would still earn a C or D from SSL Labs, weak ciphers enabled, TLS 1.0 still accepted, HSTS missing, a certificate expiring next week because nobody

A site-to-site VPN encrypts all traffic between two networks so that two offices, a data center and a cloud VPC, or your infrastructure and a partner's, communicate as if they were on the same private LAN, even though the packets cross the public internet. IPsec is

Meta Description Featured Image Alt Text An SPF TXT record being evaluated left to right against a connecting mail server's IP address. Most SPF references drown you in eight mechanisms, eleven macro letters, and two modifiers as if you'll use all of them. You won'

DMARC gets asked to do jobs it was never designed for. Teams reach for it as a spam filter, a phishing filter, a general trust signal. It's none of those. The protocol answers one deliberately narrow question: did the owner of the domain in the visible From address

The appeal of a tunnel is that it flips the usual exposure model. Instead of poking a hole in your firewall and accepting inbound traffic, the tunnel client opens an outbound connection to a relay, and public requests come back down that pipe. No open ports on the origin, no

OpenClaw is a self-hosted autonomous AI agent — it manages email, schedules events, and runs terminal commands on the host it lives on. That last capability is the whole reason the install needs more care than the average web app. An agent that executes shell commands is, functionally, a remote

I moved my Obsidian vault off Obsidian Sync and onto my own box about a year ago, and I've never looked back. The plugin that makes it work — Self-hosted LiveSync — talks to a CouchDB backend, gives you real-time sync across desktop and phone, and end-to-

A few years back, self-hosting was a niche thing. You'd run Nextcloud on an old laptop, brag about it on a forum, and move on. Now it's practically a movement. Every other thread is someone pulling their photos off Google, their notes off Notion, their
