Wiring Codex on Dockerized Omniroute

For anyone running Codex against multiple backends - official OpenAI, Kimi or DeepSeek endpoint, whatever happens to be cheapest or fastest that week - putting omniroute in front of it means Codex only ever needs to know about one base URL, while omniroute absorbs the churn of provider outages, rate limits, and credential rotation on the other side.

Deploying Omniroute on Docker

Running omniroute on Docker is the best default for me simply because I don’t want a global npm install polluting my host node environment, and it composes cleanly whether the box is a home server, a VPS, or my throwaway VM.

Running Kali Linux Containers on a Linux Server with Docker

Kali Linux ships official OCI images under kalilinux/kali-rolling, kalilinux/kali-last-release, and kalilinux/kali-bleeding-edge. They are deliberately minimal, containing little beyond the base userland, so tooling is layered on top through Kali’s metapackages. That makes them well suited to disposable, reproducible assessment environments on a remote server: you get a clean toolchain per engagement, isolated from the host and from each other, without maintaining a full Kali VM. Use them only against systems you are authorized to test.

Normal Form Designators

Brian Cantwell Smith is one of the many people who are far smarter than I am. His MIT thesis Procedural Reflection in Programming Languages — which is something else — is how I first became aware of him.

Installing Linux on External SSD

I wanted to install Linux on a portable SSD and make it bootable from my laptop, it required UEFI support. I came up with my own method since I couldn’t find a better way to do it online.
