@dhh I have a friend who supports the Ukrainian army (indirectly via an NGO) by producing drone parts in his apartment in Poland and then sends those to Ukraine

Ukrainians have really perfected the supply chain in those four years

@marckohlbrugge Wealthy people invented this to confuse the rest of us

@dhh I live in Germany and one day wanted to take a picture of a paper hanging on a board listing what kids needed for a school trip

I was yelled for doing that so I asked for a pen and paper and wrote it down

can't make this shit up

Custom linters have been the biggest unlock for my AI workflow lately.

I spent too much time babysitting the models even though I have a CLAUDE.md and .claude/rules that enforce certain behavior.

So I spent some time writing strict, custom linter rules and now when Claude uses patterns I don't want, the linter blocks it, and the agent auto-corrects.

And when used with /goal, it runs until all code is fixed.

For the first runs, I used only warnings not errors so that my CI does not fail. But now, after fixing all violations, I swapped with 'error' and it works like a charm.

Scarcity is a choice. Some arguments from the book Abundance come to my mind:

All the issues around housing, old infrastructure, slow innovation are self-inflicted, by design.

Since the 70s, the progressives/liberals have focused more on blocking development than actively building abundance. And conservatives are allergic to effective government action.

This scarcity feeds populism, on both sides.

A government should step in places where a single company can't create an ecosystem on its own. That's their primary role: de-risk, fund basic research, coordinate across many actors. Make big bets.

Like with the space program in the 60s, penicillin production during WW2, solar.

@marckohlbrugge the paradox here is that unit costs per token are falling but the inference spend is rising because the usage is through the roof. And also most of the model companies have agentic systems in place that consume much more tokens per task than just simple prompting one agent

@danshipper the "my AI stack is a geopolitical risk" was not on my list tbh

[piotrek @dopiotrek]

llm models are not the bottleneck

context, tooling and infrastructure are

[piotrek @dopiotrek]

we're entering a new software/agent development era

the bottleneck was never coding speed

it's coordination, review cycles, the 47 repos that all need the same patch

the only way past that is decoupling work from human attention

how?
background agents and software factories

@paulg LinkedIn is for middle management primarily, the part of an enterprise that is being compressed the most by AI

They're circlejerking by refusing to acknowledge that

@TaylorPearsonMe @danshipper @lennysan Dan and the Every crew are a great counterbalance to all the AI doomers out there. I like how they push what’s possible with this tech and even seeing that I think we barely scratch the surface

Fable 5 is the biggest step up I’ve felt in our models since Opus 4.5 back in November. After 4.5 came out I uninstalled my IDE when I realized that I’d been doing 100% of my coding in a terminal for a few weeks. With Fable, it’s felt like Claude has stepped up from being a coding agent to a thought and design partner in building the product. Fable has judgement, taste, and dimensionality in a way that previous models didn’t, leading me to trust it more with the most complex work.

I think the first time I had this realization was when I asked Fable to debug something. It is the first model I have used that was so methodical and precise, taking measurements and adding logs then verifying that it truly fixed the issue before declaring victory.

There’s nothing in claude code’s prompting telling the model to do that, it’s just part of its personality. It really has this “big model smell” that I haven’t felt before.

/loops posts everywhere today

still remains a mystery what it is though

everyone seems to have their own interpretation

[Peter Steinberger 🦞 @steipete]

Here’s your monthly reminder that you shouldn’t be prompting coding agents anymore.

You should be designing loops that prompt your agents.

@jasonfried I like industries that are hands-on, with no moats, super fragmented

like commercial drone pilots. I started building a stack for people who run one- or two-person businesses, occasionally bigger teams and that need to stitch together multiple tools to get the work done

[piotrek @dopiotrek]

@jasonfried chats are fine for initial workspace setup or later customising it but I wouldn’t want to open the app and stare just at an empty message box

And they have BLIK (but only in Poland)

So deserved, Revolut is an amazing company and significantly changed my life

Before Revolut I had so many problems with banks

I used to have a Dutch bank called Rabobank who would freeze my card at random times while I was traveling, and no they didn't even have an unfreeze button in the app, I mean they barely had an app

I'd literally have to fly back to Holland and go into the bank office in my tiny hometown to then make an appointment with them to unfreeze it

One time in I think 2014 I was in Bali and they froze it, I flew back and at the bank office they said it was time for me to get a mortgage, when I said I didn't want one they said do you have insurance? They were freezing my card to then use it to make me come to their office to then upsell me shit

Another time in 2017 (I think some of you remember) they froze my card in the US, and with no money I became homeless, luckily X (back then Twitter) helped me out and you all ordered Ubers for me on request and @manuthan gave me a place to sleep at @outsiteco in Venice

You don't hate dinosaur banks enough!

After experiencing all that I got Revolut and I never had any issue like that again

(Well except for moving to Portugal where I was forced to open a Portuguese bank account at MillenniumBCP, which was possibly an even worse experience than Rabobank, my premium package private banking account manager would always be unreachable and only email me to tell me she'd go on holiday and would be even more unreachable 😂)

Revolut has been my main bank app for the last decade and it's been wonderful, I've pumped millions through it and it barely flinched, sometimes they ask me documents to prove where the money comes from, but that process is super smooth and via chat

Revolut is another great example that you can make something that makes everyone's life significantly better and society will reward you by making you rich!
