The best accounting software for a freelancer is decided by the record, not the receipt: who can read your books, what the entry tier actually unlocks, how cleanly you can export, and what survives a migration. A sysadmin review of QuickBooks Online, Xero, FreshBooks, Wave, Zoho Books, and the self-hosted family (Invoice Ninja, Akaunting, Frappe Books, GnuCash), including what to check before you sign and the one case where self-hosting your books is the right call.
The best email for a law firm is decided by the archive, not the inbox: retention, legal hold, eDiscovery export, audit logs, and the tier that actually unlocks them. A sysadmin review of Microsoft 365, Google Workspace, Proton for Business, Hushmail, Zoho Mail, and the one case where self-hosting is the wrong answer.
Docker and Incus both run containers on the same Linux primitives, but they wrap the kernel mechanism in different abstractions: Docker packages an application, Incus launches a whole operating system. A theoretical comparison of application containers and system containers, the lifecycles each one assumes, and when each unit of management is the right one, with links to our Proxmox vs IncusOS coverage.
Why the 3-2-1 backup rule fails when ransomware and compromised root credentials are the threat: immutable and offline copies, quarterly restore drills, recovery key management, and backing up the configuration that defines your stack. A hands-on sysadmin guide.
After 90 days with self-hosted Immich, the remaining question was what else exists: Ente Photos, the end-to-end encrypted Google Photos alternative that is both a polished cloud service and a fully self-hostable server. A hands-on comparison of Immich, Ente cloud, and Ente self-hosted, with costs, family plans, referral terms, migration, and an honest decision rule.
Dependabot is built into GitHub and zero-config; Renovate is the configurable bot that runs on Gitea, Forgejo, GitLab, and GitHub alike. A hands-on sysadmin comparison: real config for both, the best use cases for each, and the Renovate difficulties that only show up after the onboarding pull request.
Durable execution is the difference between automation that mostly works and workflows you can trust with money, mail, and user data. A practical architect guide to what durable workflows are, the use cases that need them, and an honest comparison of Temporal, Hatchet, Conductor OSS, Apache Airflow, and BullMQ, including the self-hosting footprint of each.
