Say the Thing You Want

You’re in a 1:1 with your manager, and things are going just fine. You talk about the project and that other thing. Toward the end, she asks: “Anything else?”

And there is something else. You want to lead that new initiative. Or move to a different team. Or you’ve been thinking about what stands in the way of your promotion. The thought is right there, sitting in the back of your throat. You’re going to say it, and then… “Nope, all good.”

You get out of the call feeling a specific kind of regret. You rationalize it somehow and then tell yourself you’ll bring it up next time (you won’t).

paneru

Paneru is a MacOS window manager that arranges windows on an infinite strip, extending to the right. A core principle is that opening a new window will never cause existing windows to resize, maintaining your layout stability.

opensre

The open-source framework for AI SRE agents, and the training and evaluation environment they need to improve. Connect the 60+ tools you already run, define your own workflows, and investigate incidents on your own infrastructure.

kubedock

Kubedock is a minimal implementation of the docker api that will orchestrate containers on a kubernetes cluster, rather than running containers locally. The main driver for this project is to run tests that require docker-containers inside a container, without the requirement of running docker-in-docker within resource heavy containers.

redis-operator

A Golang-based Redis operator that will make/oversee Redis standalone, cluster, replication, and sentinel mode setup on top of Kubernetes. It can create Redis setups with best practices on Cloud as well as the bare metal environment. Also, it provides an in-built monitoring capability using redis-exporter.

sem

sem is a semantic version control tool that works on top of Git. It parses your code with tree-sitter, extracts every function, class, and method as an entity, and diffs at the entity level instead of lines. This means you see "function blahh was modified" instead of "lines x-y changed."

zeroserve

Zero-config, fast io_uring-based HTTPS server.

zeroserve serves a website packaged as a tarball, and handles hot-reload via SIGHUP.

pg_durable

Long-running, fault-tolerant SQL functions for teams that already keep their state in Postgres and want to stop stitching together cron jobs, workers, queues, and status tables to make background work reliable. Define the workflow in SQL, let pg_durable checkpoint each step, and resume after crashes, restarts, or failed steps.

Durable execution is now a standard industry pattern, and pg_durable brings it inside Postgres with no extra service infrastructure required. Part of our mission to bring compute close to data.

Life is too short for a slow terminal

Practically all of my work happens inside a terminal. Git, kubectl, tmux, ssh'ing into a server, open practically the entire day. Something I use that much has to be fast. Any lag in opening a new tab, typing a character or hitting tab for a completion is something I feel hundreds of times a day. It's death by a thousand cuts.
