Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
One bundles your whole toolchain, the other lets you build anything from parts. The right pick depends on how much glue you want to own.
We ran the same test suite on both platforms for a year. Here's where CircleCI earns its price, where GitHub Actions wins on simplicity, and what the bill actually looks like.
We've run both in anger. Here's the honest breakdown of maintenance, cost, and flexibility, plus when Jenkins still earns its keep.
A production-focused GitHub Actions guide: reusable workflows, least-privilege permissions, keyless OIDC to the cloud, SHA-pinned actions, environments with approvals, concurrency-safe deploys, and CodeQL/Dependabot gates — with copy-paste examples.
We've shipped production pipelines on both. Here's where GitHub Actions wins, where GitLab CI wins, and how to pick without regretting it in six months.
We had the same 180-line build workflow copy-pasted into 60 repos. Fixing one bug meant 60 PRs. Here's the reusable-workflow setup that made it one.
We rotated a leaked AWS access key that a workflow had committed to logs. Switching GitHub Actions to OIDC federation meant no static AWS keys exist to leak in the first place.
A prompt tweak that helped one case quietly broke twenty others. Here's the CI eval harness we built so that never ships silently again.
Our M-series laptops built arm64, our CI built amd64, and prod pulled whichever tag won the race. Buildx and a manifest list ended the chaos.
After running both in production across a dozen clusters, here's where Flux and Argo CD actually differ and which one we'd reach for now.
State drift is silent until a deploy fails or an outage reveals it. The scheduled plan-and-diff pipeline that surfaces console hotfixes and manual edits while they're still cheap to reconcile.
Most CI caches either miss constantly or restore stale junk. The cache-key discipline, scope boundaries, and measurements that turned our pipeline cache from theatre into real minutes saved.
