Have your AGENTS.md end each workstream with a little haiku about the work it just did. It's a nice little punctuation mark between trying to comprehend rheams of AI generated text all day long.

I think we are simply lucky that most internet-connected devices today don't have inference-capable GPUs attached. If they did, I think we would be dealing with a self-replicating LLM-based malware in the immediate future.

Quietly ready for another load-bearing week.

Getting back into context on a Monday morning on a big project I have been developing with agents is _much_ harder than it used to be when I wrote code myself 🥲

I feel like I spend a lot more time convincing an agent programming in Python/JavaScript to make sensible code than I do in Golang. Agents writing code in Golang just seem to write nicer code to begin with, without a bunch of arguing about module structure, etc.

I was 25 and had been working full time for about a decade before I took more than a week off for the first time. If you're working this much, I highly recommend finding some more time for yourself. If nothing else, it's great for your productivity.
At Meta you get to take "re-charge" every five years. It's effectively a 1 month sabbatical. Just took mine (after 6+ years). Best perk ever. I was trying to think the last time I have gone 1 month without a job and I think it was summer after 6th grade. It's been some 25+ years. I cannot overstate how good it felt. Anyways, back to building! Tons of cool stuff in the pipeline.

I came across a report from Google on Go being an ideal vibe coding language this week. I've been using it to build a new testing framework this week, and it's such an easy language to review compared to Javascript/Python/C which I've been working in recently.

Man, does anyone else remember CPU overclocking? I remember reading about folks using liquid nitrogen to cool pentium CPUs to overclock them to ~5ghz back in the day. I wonder if people are still doing that.

Does anyone remember back when Anthropic released Fable and told us all we'd have to pay API rates soon? Then Trump banned them, OpenAI speed-ran the Sol launch, Anthropic caved on API pricing and bundled Fable, and then the open models all caught up. Man, those were the days.

Poly-repository structures optimise for making it easy for specialists to work independently. Exactly the opposite of what you need for AI-empowered generalists to be productive. You'd be hard pressed to convince me to start a new project without a monorepo right now.

Anthropic's Claude Code harness is surprisingly sticky, and keeping "integration feature parity" between harnesses is very manual. It's doing a great job of keeping me using a model other than the one I'd most like to be using, particularly when I'm too busy to migrate config.

Suspiciously close to when Fable was supposed to change from bundled billing 👀
GPT-5.6 sol launches thursday! happy building

I'm honestly surprised by how excited I am about this 5 day extension 😂

The RAM shortage is getting crazy. I was speccing up a platform build about ~2 weeks ago on Hetzner, then came back to it today to finish it off... oof: AX102 — 16c / 128 GB / 4TB NVMe: €144 → €452/mo (~3.1×) AX162 — 48x / 256 GB / 4TB NVMe: €244 → €842/mo (~3.4×)

Been thinking about very low cost / free alternatives to SaaS a lot recently. My thinking is tending towards downloadable desktop/mobile apps being the best fit for most single user software. Download and run it locally. No cloud backend to worry about. No pager. Beautiful.

Jeez what a buzz kill 🤣
Replying to @elonmusk
What Elon calls the future, God has already marked for fire. Elon talks about future tech as if humanity will have the time to reach it. But God already holds the keys to mass, energy, antimatter, and every law of physics. Man speaks of future technologies; God has already written the end. Humanity will not ascend, it will be interrupted. The age will collapse long before humanity ascends.

I'm confused. Software keeps going up in price. But Moores Law continues as expected, and the cost of building software has never looked better thanks to AI. So it's not the cost to run it, or the cost to build it. What gives?

I haven't heard someone say riced in years. It reminds me of shlomifish.org/humour/by-oth…, forum posts by Gentoo users in the early 2000s. Never forget: compiling your kernel and userspace from source is the path to true performance. Naturally, I ran Gentoo when I was a teenager.
I think the funniest recent interaction was standing in line for coffee in SF and someone stops and goes "WAIT. WAIT HERE." (no other context yet). I'm in line so I'm not going anywhere. He runs back with his open laptop to show me Ghostty riced the fuck out. It was beautiful.

I was at Halter back in 2017 where I lead software engineering for the MVP, alongside a lot of great people. Every year now I continue to watch the valuation go up with each new round, and it brings back a lot of fun memories. Great to see them continuing to kick massive goals.
