Working between standard and custom Codex builds
My current setup uses an Ollama-enabled Codex fork as a specialized worker runtime alongside the OpenAI-signed build.

Why Llama 4 took minutes to load
What looked like a context-size or memory problem on my Strix Halo system turned out to be a model-loading problem tied to mmap.

Routing and qualifying Ollama-backed Codex workers
My next round of Codex work added Ollama model discovery, provider-aware Desktop selection, a cloud-only root picker, and task-shaped worker qualification.
Turning Ollama-backed Codex subagents into a usable worker pool
After plaintext transport worked, I added role-aware concurrency, context rollover, worker inspection, cleanup, and safe private tools.
Making Codex subagents readable to Ollama providers
I changed Codex to route multi-agent messages by provider, keeping encrypted transport as the default while adding a plaintext path for Ollama-compatible endpoints.
How to add email to a domain you already use
Set up email for an existing website domain with Cloudflare forwarding, a Gmail mailbox, and Resend SMTP.
Codex auto review can get expensive
Auto review is useful safety infrastructure, but it can quietly become a large part of Codex usage when tasks keep crossing protected boundaries.
The cheapest model call is the one you avoid
How deterministic retrieval, reusable semantic context, and smaller models can reserve frontier-model attention for the work that needs it.
A code graph is not repository memory
What code graphs can tell an agent, what real repository questions demand, and why useful memory needs a semantic layer.
Giving Coding Agents a Map
An introduction to RepoMemory, a local context layer that helps coding agents find the right part of a repository.
Using Ollama models with Codex providers
Why the goal is mixed-provider Codex delegation, and where today’s provider path breaks down.
Prompt injection has a lot in common with SQL injection
Why prompt injection is dangerous, what adversarial testing can catch, and why passing those tests is not a guarantee of safety.
Why Llama 4 took minutes to load
What looked like a context-size or memory problem on my Strix Halo system turned out to be a model-loading problem tied to mmap.
Building a remote MCP time server
Building a remote MCP server so AI agents can ask for real time, timezone, and duration data instead of guessing.
The runner was the recovery path
Using a workflow runner to recover access to a host, and why runners need to be treated as serious infrastructure.
A note on performance in the registry control plane
Reducing repeated registry work with cached catalog data, paginated tag loading, and event-driven cache warming.
Registry Control Plane is public on GitHub
Registry Control Plane is now public on GitHub, along with its container packages.
Making the registry control plane more responsive
A short note on making the registry control plane easier to use on phones and smaller tablets.
Adding a local cache to a Forgejo runner
Using a temporary local BuildKit cache in a Forgejo runner to speed up repeated registry control plane builds on limited hardware.
Working on a registry control plane
A May 2026 snapshot of building a registry management layer around Docker Distribution.
A quick note on my ASU builder changes
Operational changes that made my OpenWrt ASU builds more reliable when the official builders were overloaded.
