Ten years of tmux, and the 1,495 lines of zsh it cost me

Tue, 22 Sep 2026 11:30:00 +0530

TL;DR I’ve used tmux since 2016 because I can script it. Over ten years my config grew into 1,495 lines of zsh across 13 scripts, and in May 2026 the status bar alone was burning 15.4% of a core on battery. The fix was one #() call instead of six, and the scripts moved into one Rust daemon, tmux-companion. The bar costs 1.8% of a core on a spike and 0.3% idle now.

Claude and my stale posts

Thu, 17 Sep 2026 06:30:00 +0530

This post itself is the exception to what follows: Claude wrote it from the week long session, using my notes and its own commit history, and I edited it. The career posts and the hosting post started as my writing. This one did not.

This is a first draft. I have used Claude on this blog for two days. I will come back to this post when I have used it for two months.

Free static hosting with Cloudflare Pages, Terraform and GitHub Actions

Thu, 08 Jul 2021 20:23:49 +0200

TL;DR You have a static site and a domain. Cloudflare Pages serves it, Terraform sets up the hosting from a few files in your repo, R2 keeps Terraform’s memory, and GitHub Actions runs it all when you push. The bill is zero. The example repo walks through the setup one commit at a time.

I wrote the first version of this post in 2021. Since 2019 I had hosted a few sites for friends and family on AWS: S3 for files, CloudFront in front, Cloudflare for DNS only. Route53 charged half a dollar per domain per month, more than S3 and CloudFront together for sites that small. That post was about shaving that fee.
