A new year's resolution is to write more technical blog posts about challenges we're working on for Warpcast + Farcaster. Here's a post discussing our migration from Faktory to our own hand-rolled job processing framework, and the lessons learned. https://paragraph.xyz/@sds.eth/building-a-job-processing-system

Taking a moment to reflect, I can’t help but marvel at the fortune that we have experienced as humans. Yes, we have our challenges. There are things to be mindful of, even fearful of. But the universe continues to demonstrate that we are on a trajectory that is full of opportunity. If there’s anything we need to embrace right now, it’s optimism. Wishing everyone a happy, healthy new year. Let’s make this next solar revolution meaningful, and keep this experiment going.

Been wondering when we would see thorium reactors for over a decade, as they are inherently safer than uranium-based reactors. Sad the US isn’t leading the charge, but hopefully this prompts further investment. https://spectrum.ieee.org/chinas-thorium-molten-salt-reactor

Using stored procedures for complex query patterns makes sense, but I don't have an intuition for the kind of query complexity necessary before seeing tangible benefits switching from prepared statements. Glad someone is experimenting! https://github.com/pg-nano/pg-nano/

We've released a simple tool for those running on AWS: https://github.com/warpcast/awsh The Snapchain team has been running a number performance tests to identify and eliminate bottlenecks in the Rust implementation. These tests run in our AWS environment because of the quick setup+teardown convenience. However, connecting to these instances and dealing with SSH keys in a security-conscious way has always been a pain, along with managing host key verification of a constantly revolving list of reused IP addresses. Why not get rid of the need for SSH client keys + host keys entirely? AWS EC2 Instance Connect has the tooling, but it doesn't work like the ssh executable does so it feels clumsy. We've merged the tools with a simple script to make it easy to hop on boxes in your environment.

Recently switched from using Z-Shell for the past decade to Fish [1]. When paired with the Fisher plugin manager [2] and the Tide prompt plugin [3], it's been a much more pleasant experience than I was expecting. Like many before me, I have synthesized my setup into a bootstrap script I can run on a brand-new mac and everything Just Works™—you can find it here, though I recommend you use it for reference and not for your personal setup, as it is very opinionated and changing often: https://github.com/sds/.files?tab=readme-ov-file#dot-files It's a pretty stark departure from my prior solution, but after a decade the YAGNI principle [4] has really rung true for me—I spent far too much time making my configuration framework [5] customizable to an unnecessary degree.

When you’re working with @sanjay @dynemyte and @suurkivi, best to brush up on some background.

As an immigrant, there's something deeply satisfying about the world's most valuable company being founded by an immigrant and headquartered in America. https://www.washingtonpost.com/business/2024/11/05/nvidia-tops-apple/

Switched over from Docker Desktop to OrbStack (https://orbstack.dev) on my mac for the last month, and a way better experience—well worth the small cost. Warpcast's test suite runs almost twice as fast under OrbStack compared to Docker Desktop (running a few containers).
