Zram, zswap, swappiness, and the OOM killers — the full ladder Linux climbs when RAM runs out, and what to actually run.
#6186: A Virtual Disk Inside Your Linux Filesystem
Loop devices let a plain file act as a real disk — format it, encrypt it, mount it from fstab. Here's what works, and what bites back.
#6170: One Endpoint, Many Boxes: Local LLM Routing
A LiteLLM-style proxy can fail over between your own GPU boxes and the cloud — but it can't see your VRAM.
#6166: Turning a Drifted Server Into a Rebuildable Playbook
Your server grew for years. Now you want a recipe that can rebuild it from scratch. Here's the honest path from drift to playbook.
#6124: One Vault, Two Readers: Secrets for a Home AI Gateway
One source, two readers — not two copies kept in sync. How a home AI gateway should actually get its API keys.
#5969: Ubuntu 26.04 LTS: Is Staying on LTS Still a Trade-Off?
Ubuntu 26.04 LTS shipped in April. Point releases, HWE kernels, and SRUs have quietly closed most of the freshness gap — but not everywhere.
#5968: Gentoo in 2026: Still Worth Compiling?
Twenty years on Linux and he's never tried Gentoo. In 2026, does the compile-everything reputation still hold?
#5964: Containers vs VMs for GPU Inference: What You Actually Pay
Containers cost 0.03%. Passthrough VMs cost 1%... or 36%. Same hardware, different systems — here's how to tell which you'll get.
#5918: Splitting One Camera's Audio for a Baby Monitor
One IP camera, two jobs: an open audio line for the nursery and Frigate's cry detection. Here's how go2rtc and Icecast fit together.
#5912: Building Your Own CRM with AI: Where to Start
AI can't write your CRM for you — but it can remove the friction. Start with the schema, not the code.
#5911: What Revit 2027 Actually Costs to Run
Michael wants Revit live for AI agents 24/7. The GPU isn't the real bill — the licensing is.
#5870: Homebox Fork's Two Backend Scripts Need a Real Job Runner
A Homebox fork has two incremental scripts — WebP conversion and AI image enrichment — and no scheduler built to run them safely.
#5830: Serving Your Own Fine-Tuned Model in the Cloud
You fine-tuned an open-weight model. Now how does anyone actually talk to it? Dedicated GPUs vs serverless inference, and the math that decides it.
#5782: Unraid in a VM: When the License Is the Wall
Daniel wants Unraid's parity array without Synology's lock-in. The technology works. The licensing is the wall.
#5773: Declaring Environments: Compose, Nix, and the Agent Boundary
Docker Compose, Nix, devcontainers, microVMs — how automated provisioning works, and where the boundary moves when an agent needs a workspace.
#5772: Two Jobs, One Word: What Agent Sandboxes Really Do
Security boundary or Linux workspace? The word "sandbox" quietly split in two — and the split explains where agents actually run now.
#5574: Ephemeral Containers and the ADE Label Nobody Owns
Claude Code's cloud sessions spin up a fresh VM every time. Here's what that breaks, and the new term for what Daniel actually wants.
#5523: Where Does the Coding Agent Actually Live?
The agent process is moving off your laptop. Local appliance, SaaS workspace, or your own VPS — three answers, no consensus.
#5465: Packaging AI Pipelines So They Actually Get Reused
Daniel's podcast pipeline works — so why can't he reuse it? Recipes, containers, and Hebrew code-switching TTS.
#5319: Focus Stacking Without the Phone App Guesswork
Your phone app wants three shots. The optics want three hundred. Here's how to actually stack macro focus.
#4996: Memory Leaks: The Full Taxonomy
From C to Rust to Kubernetes OOM kills — the real taxonomy of memory leaks and how to hunt them.
#4993: Cross-Cloud Failover: Can You Actually Survive an AWS Outage?
Real teams are running cross-cloud failover drills — and the first attempt usually fails. Here's what they learned.
#4973: Building a Pure AI Inference Server
Why your "AI server" should look more like a database than a web app, and how to actually build one.
#4824: Build vs Pull: Docker Deploy Strategies for Solo Devs
Where to build your Docker image and how to trigger deploys — three patterns for small teams on a VPS.
