Playing around with a Kent Beck-inspired prompt today: Before implementation, look for opportunities to prefactor the code to make the implementation easier. "Make the change easy, then make the easy change."

🚨 @Karpathy's LLM wiki concept just became a real Mac app. It is called Tolaria, a free desktop app for Mac and Linux. The goal is simple: give humans and AI agents a shared, native environment to build knowledge. It writes like a modern block editor, but saves everything as plain markdown. No databases, no proprietary formats, no vendor lock-in. And because every vault is a Git repo, you get visual version history built right into the app. The project is also a massive showcase of what AI-assisted engineering can do: → Built with Tauri, React, and Rust → 100K+ lines of code shipped → 3,000+ tests at 85% coverage → 9.9/10 code health score → 70+ architecture decision records It includes an out-of-the-box MCP server so tools like Claude Code can read and edit your vault natively. The Tolaria name and logo remain covered by the project trademark policy. Best part? Open source, free forever, no account required 🔥 License: AGPL-3.0-or-later. repo link in 🧵↓

Introducing Tolaria! 💧 Today I am releasing a macOS desktop app for managing markdown knowledge bases, and helping both AI and humans operate them. It’s free and open source, and always will be. I have been working on it for three months, and I now use it to run my life and work. I personally have a massive workspace of 10,000 notes — the result of 6 years of Refactoring — which I now operate on Tolaria. Tolaria is the main collaboration surface with my AI agents: they create new notes there, connect them to what exists, and edit existing ones. Everything is easy to understand for them, because it’s just markdown files. In a way, it’s my implementation of @karpathy's LLM wiki. Tolaria is also the biggest experiment I have ever run about writing software with AI: • 2000 commits • 100K+ lines of code • 3000+ tests / 85% coverage • 9.9/10 code health • 70+ architecture decision records I am releasing it open source also to use it as a living artifact of how I do AI coding, so you can inspect at any time things like how I write docs, what's in my AGENTS file, what hooks do I run, and so on. You can find it below: • Newsletter announcement: refactoring.fm/p/introducing… • Website: tolaria.md/ • Github repo: github.com/refactoringhq/tol… Let me know your thoughts!

We spend so much time optimizing kernels and kv cache just for the product team to waste 11ms on a react scene graph for a terminal. the abstraction tax is getting out of hand lol. @its_bvisness is right, it is literally a clown universe when a tui needs a frame budget.
We apparently live in the clown universe, where a simple TUI is driven by React and takes 11ms to lay out a few boxes and monospaced text. And where a TUI "triggers garbage collection too often" in its "rendering pipeline". And where it flickers if it misses its "frame budget".

So @naval said “Assume every team member could be an enemy spy sent to sabotage your company.” It’s brilliant because suddenly, the traits you don’t want become obvious: • Vague updates. “Working on it.” • Missed deadlines with clean excuses • Low ownership language • Hoarded context and private DMs • Process over outcomes • Defensiveness to feedback • Tool hopping instead of shipping • Silent disagreement • Status seeking over building • Energy drainers • Inconsistent output • “That’s not my job” thinking Sabotage doesn’t look like betrayal. It looks like slowness, ambiguity, and responsibility diffusion. Hire and fire accordingly.
I wish I had hired slower and fired faster.

Look at these 2 UIs. One of them will 100% outperform the other for one reason: The Doherty Threshold. Here's how this psychological principle works & how to use it in your products:

I am done with the energy in this industry that is all about the rug pull. Fuck. That. Noise. I got into crypto because I saw Wall Street ripping off retail and I’m honestly disgusted with the amount of that crypto has replicated and exacerbated this. I don’t want to go there, but most of us still building (especially unsexy infra) have made enough in this space to be comfortable for life. The only reason crypto has made any progress over the last 3 cycles is because of those who stayed building with long term vision. It’s the people who stick with it when the tide goes out and there’s no hype and no money to be made — and then who push even harder when the wind is at their back, ignoring the “easy money” grab right in front of them because they know there’s a bigger picture. It’s Vitalik, it’s Cobie, it’s Toly, it’s Hayden. The reason crypto hasn’t come further in 15 years is the fucked incentives that so many other builders fall prey to. Ship a token, make a few 10’s of millions, get out. You all know who falls into this category. If you think that the PROBLEM with a project is that they didn’t ship a token and dump on retail at the top of the market then YOU are the PROBLEM.
the problem with all of these infra memecoins is that the coin launches 18 months after the narrative dies shared sequencer coin would have ripped in 2022 restaking coin and intents coin would have ripped in 2023 they are obvious zeroes in 2025
