The mischievous, wish-granting nature of AI tools (via Kent Beck)

It's beginning to crumble

The first steps of my breadcrumb tool

I had a breakthrough while working on bjornstack that made me realize how I could make an MVP of breadcrumb, the tool I’ve wanted to build for ~18 months.

So anyway, bjornstack is my opinionated take on how to write code, aimed at constraining and guiding genies to get their work done. And while working on it, like I have been whenever I’m working with genies, I got thoughts that I wanted to explore later, or ideas for other things I’m working on. I realized that since I started using beads capturing in this project has gotten easier, while chatting I just mention we need “a new bead about x because y provide all the context we have here” and then there’d be a new bead linked to the work we were doing, and I can just pick it up later.

But as soon as it was something for another project, or even just “I need to remember to pack the charger when I leave the office today,” then I had to break out to capture the thought, and blow my stack and lose my flow. And if I don’t capture it, I lose the thought.

You don't know what you don't know

Why you shouldn't just 'trust' AI genies

I shared a prompt to help create “AI expert prompts” to help you learn a domain, and I’m realizing I didn’t mention the dangers. As every company that gives you a genie to talk to says “they can get things wrong.” The problem is that as a non-expert you don’t know what you don’t know, so you don’t know when the genie is so confidently wrong.

When I started a company I figured, why not do the books myself for the first couple of months and then pay someone to review it later? I created a genie armed with the standard Swedish accounting plan, verified some of the big things I did (inject some extra starting capital) and could find clear examples of how it’s done. I did some other things and just did as it said, but did get a bit complacent because the big one just worked, and didn’t research as thoroughly.

My genie has a genie

A prompt for building experts to help you see their world

I was reading Our First Accelerated Expertise Course from Commoncog, and the section Why This Training Approach is So Weird got me keen on seeing if I could get the genie to help me build experts for sensemaking, so I can learn to see the world as those experts do.

So far I’ve created one expert, and I’ve had a useful conversation (I realized I was not seeing the forest for the trees), so sharing what I have and leaving a crumb for the future. 🙂

Fixing Mastodon URL truncation in n8n

I have been working on automating my POSSE setup, and ended up trying n8n and it has been a great experience, there are so many plugins that it’s mostly just wiring things together.

But, I discovered that despite being within the character limit, one of my URLs were truncated when posting to Mastodon. This is because Mastodon does something non-obvious: it treats all URLs as 23 characters, no matter if they’re shorter or longer.

Arvid Nordquist mellanrost coffee recipe

…making do without the gooseneck

My recipe for Arvid Nordquist mellanrost. I started by trying to replicate The Ultimate V60 technique by James Hoffmann (which is what I normally brew) and I realized just how hard it is to control the flow rate now that I don’t have my gooseneck kettle (being shipped from Singapore), and I hadn’t really realized just what a difference controlling the pour makes for the taste!

Angry at the genie

…getting exactly what I wished for, eventually

A colleague mentioned he’d like a genie coach to practice first principles thinking, because we had talked about the cooking coach I made and have been using. So I decided to give it a try, whipped up a prompt, and gave it a spin.

I had a problem I’d been working on and wanted to see if there was another way of thinking about it. I also asked it to add behavioral economics as an angle because I’ve been interested in pulling in a more human angle to my thinking (still learning what that means).

DIKW pyramid when working with genies

…classification of different types of understanding

Curtis shared the DIKW pyramid, that I hadn’t heard of, and said that he feels that the genies helps him process the first two layers much more quickly than he can alone, that it can somewhat help penetrate into knowledge but not much. Which allows him to spend less time in D/I (collection) and then more to then K/W (processing?)

The pyramid of knowledge with a base of data, the next layer built of information, then knowledge and finally wisdom at the peak.

Anthropic on prompting for agents

…and musing on genies possibly teaching empathy

Anthropic has released some recordings from their Code w/ Claude event in May and the Prompting for Agents presentation’s “key principles” are basically to empathise with your agent, imagine it’s a brilliant new grad, book smart but missing all things practical at their first job: You need clear concepts, unambiguous instructions, and well-named and designed tools.

I’m more than a little amused that we’re basically coming to a point where, if things pan out with the genies, then the best wranglers will be the ones that can empathise the most with others. Then again, I always thought the brilliant asshole was the exception, they only survive if they’re in charge or are legacy to the company. And sitting in on the review meetings at work… it’s definitely the ones that help the team that we like the most, even if we sometimes need to push them to have their name on something so people don’t overlook them.

When everyone gets a genie

learning to handle expertise you didn't earn

We’ve always had to figure out who to trust for expertise, but until now, that access wasn’t universal. Used to be the bloke at the pub who ‘knew things,’ or that friend of a friend who could fix computers (me as a kid), or books if you had the patience. Rich people had their ‘real’ experts on call, though Bernie Madoff shows how well that could work out.

The internet changed things, sure. Suddenly you could reach out to actual experts, find communities, and learn from people across the world. But you still needed judgment, because you could also find a community that agreed the earth was flat, so, you know, mixed bag.

What hasn’t changed is we’ve always had to figure out who to trust. What’s changing is how we get our answers, and who gets to sound like an expert.
