The new projects feature in Claude Code is cool. I like talking in one thread while the orchestrator delegates the tasks to subagents. I also feel like it obfuscates too much. Tool calls, thinking traces: I don't really feel like I know what's going on anymore. That's fine when I'm not at my computer or on my phone, but it would be nice if I could look into stuff a little bit more when I'm behind my laptop. Maybe I will stick to a 24/7 on Mac Mini + Remote Control. I do really like the updated Claude Code app though, CLI app is dead to me.

It's a pretty chaotic and annoying family, yes, but they are not on their own phones. I think that's the main message here: this is a device that everyone interacts with that is in the middle of the household. There are some interesting second order effects to explore.

Maybe, just maybe, there is a small loop hole for fully on device apps. Let's assume that the local models that Apple and Google ship with their OS will become good enough for most tasks. In that case, some use cases, where you want your data to stay private, could be feasible. Maybe your health app, finance app, calendar app, photo app. I could also see a future where nobody gives a fuck and just uploads everything to our AI overlords though, like Pieter is saying.

Just learned that this is called a dynamic workflow. I really enjoy the way it works. Your main agent stays responsive and uses way less context that normal. I instructed it to also use Sonnet and Haiku subagents. It worked for quite a while (hours) and the result was better than when a single agent with some subagents worked for a prolonged period of time. Less drift. I tried this before with Fable and that just used too much tokens. With Opus I used around 20% of my weekly budget on max20 for a 4 hour session.

I really like this overview and structure Claude Code creates when using ultracode. It's way better to get an idea what's happening. I have the feeling the subagents also don't use that much tokens because their task is well defined.

One of my goals for this year is to create an iPhone app. The main rule: make an app that I want to use myself. Thought it would be fun to create a fully local app, without a server. Mainly for privacy purposes. Turns out that there are many more advantages that I didn't think of. Because the app runs locally, it can easily scale. And because there is no server, my costs are non existent. This means I don't have to choose for the standard subscription model. The app is small, super fast and works offline. I don't have to comply with privacy regulation, because I don't store data. I can't get hacked. I mean I can, but there is no customer data to steal. The more I think about it the more I like this model. There are some downsides, but it's also quite fun to think outside of the box to solve them.

Dutch Government: > Hold a Bitcoin ETF = Capital gains tax > Hold Bitcoin on an exchange = Paper gains tax This is what they came up with after months of deliberation and a lot of pushback on taxing paper gains on stocks and crypto. The idea is that “financial instruments” under MiFID are now taxed based on capital gains (instead of paper gains, as in the initial proposal). Crypto is not a financial instrument under MiFID, so it’s taxed based on paper gains. After 2030, it will be moved into the capital gains category. But crypto is not a financial instrument under MiFID because it has its own regulation: MiCA. This part is so unbelievably stupid I can’t wrap my head around it. We got dedicated crypto regulation in the form of MiCA. We got DAC8 implemented for crypto exchanges, which requires exchanges to collect customer data and share it with the tax authority. In many ways, the Dutch crypto sector is better prepared for the new tax system than legacy banks. Many of these companies worked their asses off to comply with these regulations. Is this how you reward them? And I haven’t even started on the unintended effects for ordinary citizens. People will sell their crypto on exchanges, send the money to their broker, and buy a BlackRock Bitcoin ETF. It's literally a couple of clicks on your computer to go from paper gains to capital gains tax. What. The. Hell. This idea has so many loopholes and so many unwanted first-, second-, and third-order effects. It's a clear example of path dependency and the sunk cost fallacy. The government went down this road and apparently can't do what's best: scrap the current plan and start over. I hope they surprise me and fix this mess.

Finished. Astra made the design, then I 3D-printed it, sanded it, and spray-painted it. I like this little corner of AI. Building hardware is undercrowded (for now), and it’s really rewarding. It's just fun to make 'real' things instead of software. For this project, I already had the exact dimensions and the acrylic screen, so it’s not like Astra one-shotted it. It did get everything exactly right with the info I gave it. I’ll try Opus 5.5 later.

One of my best memories is watching Game of Thrones with my friends. Who am I going to watch my hyper-personalized movie with? Or listen to this super-specific song an AI created for me? With my AI swarm? Don’t underestimate the power of shared experiences.

Case in point: all these local food trucks think they have a unique and tasteful design. Way better than the WordArt they had before. In reality it's worse than the WordArt they had before, because it looks exactly the same as their competitor next to them.

This book is fantastic; I recommend reading it. Sebastian Mallaby has a gift for writing page-turners that still offer the necessary depth. The book offers insight into the life of Demis Hassabis, DeepMind, Google, and the transformer revolution. 5/5

AI makes me feel anxious. I'm creating more than ever, but I'm also working more than ever. It's like I'm finally accepted into the club of developers, only to hear the club is shutting down. We don't know when though.

New tutorial! This time, we're setting up Bitcoin multisig with @CasaHODL. In this video, I explain how to: - Set up a 2-of-3 vault with a @Trezor Safe 5 and @Ledger Nano S Plus - Back up your keys and wallet data - Send and receive bitcoin - Recover your wallet in Sparrow, without Casa We don't just set it up. We test the recovery too. Check the video here:

First prototype. Assembly was difficult but everything fits fine. Note that I added an acrylic screen in the front that I had from an earlier project. Combining 3d prints with acrylic can really level up the feeling of a print, make it more 'finished'.
