How an Open-Source Marketing Lab works

[A self-regulating label doesn't make you trustworthy, but means that you can be tested, which favours those who implement the protocol.]

[The goal is to make good actors provable as opposed to punishing bas actors.]

Welcome to the feudal states of AI

constant trade from local control to centralisation, from regulation to acceleration, from protection to adaptation, from ownership to access and from public oversight to industry governance. Future citizens are reduced to data sources that are constantly monitored and require continuous retraining.

Are you writing a book on software engineering?

You're focused on the output (the book). I'm focused on the outcome (understanding). AI is great for output but that is not what is needed or wanted.

Gal Costa: Cantar (1974)

You may have seen Andrej Karpathy's post on his "LLM Wiki" — Markdown notes in a Git repo, edited by an LLM, and read in Obsidian. It's a very effective pattern.

TiddlyWiki turns the vault into something live. Index files that LLMs have to keep manually in sync become computed views that always reflect reality. YAML frontmatter becomes a small queryable database the LLM can sort and filter against. And the LLM can author not just notes but small interactive views — dashboards, glossaries, journal indexes — that compose with your own customisations.

In short: a notes folder becomes a programmable surface.

Barbells

A barbell strategy is when you put most of your money into extremely safe assets, and invest a small portion in high-risk, high-reward bets. A common split is 90% treasury bills, cash, short-term bonds, and 10% options, venture bets, and volatile stocks. You avoid the middle entirely.

much of incumbent tech is looking like the kind of middle-risk investment that a barbell strategy tries to avoid.

I’m also budgeting for conference travel, since the downside of living in a low-burn locale is missing out on the network effects of a city like San Francisco or New York. Conferences create condensed versions of this network effect. So, 90% building, 10% high-intensity networking. Another barbell.
