I want tmux to feel like one cohesive environment that never goes away. When I am docked at my desk, I spread iTerm across multiple Mission Control desktops and keep a different project on each space, with some other tools I need for that specific project. Later, when I grab my MacBook Air or open Blink on my iPhone or iPad, I want those exact same panes, command histories, and scrollback.

Plain tmux attach gets close, but the shared "current window" breaks the illusion. When I switch to another window in my main terminal, all other tmux clients jump to the same window and interrupts whatever flow I was in. I wanted tmux to be stateful and multi-focus.

If you’ve ever wanted your phone to double as a full-fledged development studio (complete with SSH, live previews, and your entire workflow at your fingertips) then this story is for you. It’s about how a small experiment with Tailscale turned into a complete rewire of how I build, code, and stay connected. From private dev environments to bathtub coding sessions (yes, really), here’s how it all came together.

Every section in this story layers on the next, building toward the “I can’t believe my phone is a full dev studio” moment at the end—so if you can, read it through. The payoff is worth it.

Rust is one of the most thoughtfully designed languages of our time — but setting it up on macOS can feel oddly opaque. The standard advice is to run a one-liner like curl https://sh.rustup.rs | sh, which works beautifully but hides a lot of what’s happening behind the scenes. For developers who are more security-conscious or just prefer to know what’s being installed and where, this default approach can feel like a black box.

This post explores the different ways to install and manage Rust on macOS — from the convenience of Homebrew to the flexibility of rustup, and the transparency of manual or containerized setups. The goal is simple: give you control and understanding without sacrificing practicality.

For the longest time, sharing code from GitHub meant screenshotting or pasting raw snippets into Markdown. Both options felt brittle—screenshots hide the text from RSS readers, while copy-pastes drift out of sync the minute the upstream file changes. I wanted the readability of Emgithub, the SEO of server-side rendering, and zero third-party JavaScript.

That mix finally landed this week: a {% github %} shortcode that fetches code at build time, highlights it, numbers each line, and offers a copy button. All it needs is the GitHub blob URL and an optional style flag for light or dark chrome.

Recently, a few hours after setting up Umami with Docker and Nginx on my VPS, I stumbled into a misconfiguration that left the admin dashboard exposed to the public web. Thankfully, there was no immediate danger. Since right after creating Umami's docker instance, I have updated the admin username and password immediately, and locked it down before anything bad could happen. Still, it was a stressful reminder that small mistakes in deployment can have big consequences.

Here’s the story of what happened and what I learned along the way.

Like a lot of developers coming from Linux or a server environment, I hit some confusion when setting up Docker on my Mac. On Linux, you just install Docker and it works natively. On macOS, it’s a bit different — there’s no native Docker Engine because we don’t have a Linux kernel. That’s where tools like Docker Desktop and Colima come in.

Let me walk through what I’ve learned.

I spent the better half of today getting Umami analytics to cooperate with a static blog served through Cloudflare and an Nginx proxy. The tracking script was having issue in Safari (CORS) and Firefox (nothing showed up in the Developer Tools' Network tab).

This is the story of following the trail from mysterious redirects to CORS ghosts and finally to Firefox’s stealthy sendBeacon API.

Over the past few weeks, I’ve spent quite a bit of time experimenting with Tailscale, and it has quickly become one of my favorite tools.

If you haven’t heard of it, Tailscale is a secure, easy-to-use mesh VPN built on WireGuard. It lets your devices talk to each other as if they were on the same local network, no matter where in the world they are.

What started as a simple question — "Why can’t I reach my MacBook over Tailscale from my iPhone on mobile data?" — turned into a deep dive into NAT types, relay servers, and the hidden power of IPv6. This post documents the technical journey, the dead ends, and the final conclusion.

So the mystery: why do VPS connections work, but Mac connections fail?
