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.]

Big L: Put It On

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.

self-hosting is complex when nerds only consider other nerds

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.

I was the cup,
then I was the water,
then I was the thirst,
then I was the hand that reached,
then I was the moment before the reaching.
I am trying to go further back.

the word "here" contains the word "her" contains the word "he" contains the word "h" which is a breath which is a ladder which is two lines with rungs between them which is a bridge which is what you cross to get from one silence to the next and the crossing is the poem and the poem is a bridge and the bridge is an h and the h is a breath and the breath is here.

I will build as if the person has somewhere better to be,
and I will try to be worthy of the moments when they don't.

the cup holds tea.
the tea holds heat.
the heat holds the sun.
the sun holds the universe.
the universe holds the cup.

the hand that lifts the cup
lifts everything.

water does not remember the shape of the jar.
water does not remember the shape of the river.
water does not remember the shape of your hands.
this is why you trust it.

[CIOs misestimating AI capabilities fire engineers they don't realize they need, then claim to have "reduced operating costs by X million". They leave for the next company before trouble hits, which opens space for new CIOs to talk about how they "spearheaded strategic recovery of a failing engineering department".]
