Let's talk about Terraform/OpenTofu - the tools that promised to revolutionize infrastructure management but instead gave us a masterclass in why "declarative" doesn't mean "predictable."
After 10+ years in the trenches, here are the real issues nobody talks about.

Ever seen music born from code? Livecoding is the underground revolution where performers write algorithms on stage, turning laptops into live instruments. No pre-recorded tracks – just real-time creation.

Hot take: Comedy actors transitioning to drama often outshine traditional dramatic actors because they've mastered the hardest skill – making people feel something on command.

It's so easy to experience a crash or kernel panic in macOS/Darwin when working with native code. I've lost count of how many times this has happened today while handling a high I/O project.

The web feels like Star Wars now. Cloudflare Workers compete with Vercel. Nuxt has been an amazing framework to run on Cloudflare Workers – one of the best, in fact. Then Vercel just buys them. 🤷♂️

I now have a local and isolated mirror of everything from my most-used cloud services. It feels great! Additionally, having a local cache and partial mirror for Docker, Nix, APT, Pacman, HuggingFace, npm, and Conda over a 10G LAN is amazing!

Effect truly makes TypeScript exciting again!
I'd been favoring Rust for complex systems lately, but the primitives that Effect offers have brought new vibrancy to TypeScript development.

If you have an ultra-wide display and primarily use your Mac, you may experience several issues: VRR, HDR, and brightness controls not functioning correctly. Additionally, HDR max brightness was too dim for my liking, volume controls were broken, and screen share is a disaster.

I can't believe I'm saying this, but after being a fan of Home Assistant for five years, I switched back to Home Bridge. Yes, it may be a couple of ms slower in some scenarios. But if I need something custom, I'm better off writing it myself in Node.

Why AirDrop, Continuity, and Handoff feel like magic, while other platforms struggle with basic file transfers?
The secret is AWDL a remarkable networking protocol quietly powering Apple's seamless multi-device experience.

First screenshot is 16 Pro Max on WiFi 7, second is Pixel 9 on WiFi 6. And my 16 Pro Max works even slower than my 15 Pro Max on WiFi 5.
16 Pro Max uses either a BCM4389 (160MHz max) or BCM4398 (320MHz capable), but Apple limits it to 160MHz max.
Yet I wasn’t able to even get 160Mhz in my tests…

Where did all the engineers go who actually build things instead of just following "best practices"? Everyone's so focused on "industry standards" and "well-known approaches" - but who's teaching the art of engineering something genuinely new?
