About

Daily Ferment is built on one move, repeated every day. Take something specific that actually happened in one part of a working life. Hold it against a part of the work it has nothing to do with. Keep holding it there until a pattern shows up that is true of both. Then publish that pattern honestly, including the parts that are still uncertain.

The subjects this happens to land on are AI, engineering, leadership and fintech, because that is the work. But the subject is not the point. The crossing is the point.

Why it exists

Almost all writing about technology is organised by vertical. A site covers AI, or engineering management, or startups, and it stays in that lane. Editors know their lane and commission inside it.

The problem is that a good share of what is actually worth knowing only becomes visible when you hold two unrelated things against each other. Those ideas have nowhere good to live. A tech site will not run the leadership piece. A business site gets the technical detail wrong. So the idea either gets flattened to fit one vertical, or it never gets written at all.

There is a second reason, and it has become more pressing. Competent, polished, plausible writing is now available in unlimited quantity at almost no cost. What is not available in unlimited quantity is a named person saying exactly what they tried, what happened, what they got wrong on the way, and how sure they actually are. That is the scarce thing now, and it is the only thing this site is trying to be.

What the name means

Fermentation is what happens when you leave something alone under the right conditions and it turns into something else. It is not decay, and it is not manufacture either. You cannot rush it and you cannot fully control it, but you can set it up properly and you can tell when it has worked.

What gets fermented here is not opinions. It is raw material: a friction, a noticing, something that went wrong and then nagged. That raw observation gets deliberately exposed to a context it did not come from, and then left alone. Time passes. It comes back more specific and more transferable than the first reaction to it was.

The test of whether it worked is simple. If the claim being published is still the same as the first thing I thought when it happened, it has not fermented. It has just been typed up.

What you can expect here

• A specific, real situation before any general claim, never a general claim hunting for an example to justify it.
• What I got wrong on the way to what I now think, not only the tidy final version.
• An idea that started in one part of the work and ended up explaining something in a part you would not have connected yourself.
• Honesty about which parts of a claim are tested and which parts are still a guess.
• Something short on an ordinary day and something deeper on the days that earn it, never padded to fill a length nobody asked for.

The rules this holds itself to

These are not aspirations. They are the constraints a piece has to survive before it goes up.

1. Publish only what has actually been tried, built, managed or directly observed. Not what has merely been read about.
2. Mark every claim by how sure it is: established, inferred, or still a guess.
3. Do not delete the false start. If the thinking changed while the piece was being written, the change stays visible in it.
4. A piece is not finished until it names a transfer: a specific insight that moved from where it happened into a domain where it was not expected.
5. End a piece when the thought ends, not when a word count is reached.
6. Revisit old claims in public and say plainly when they were wrong, rather than letting stale pieces sit there quietly.
7. Do not force a connection that is not really there. Sometimes the technical thing is only a technical thing, and it gets said so.
8. Always distinguish what was tested here from what is being cited from someone else.
9. Publish something every day, but not a finished essay every day. A short, honest, unresolved note is worth more than a padded one.
10. Better to be useful to one reader who acts on a piece than impressive to a thousand who only skim it.

How claims are marked

Not everything here is equally well supported, and pretending otherwise would be the fastest way to make the whole thing worthless. So claims carry a marker.

Established means it has been done more than once and the result held. Inferred means the reasoning is sound but the evidence is thinner than I would like. Guess means exactly that, said out loud.

When a claim stops holding, the piece gets revisited and the revision is visible rather than quiet. The date on a piece is when it was written, not when it was last true.

The five kinds of piece

You navigate this site by subject, because that is how people actually look for things. Underneath that, every piece is one of five kinds, and the kind tends to matter more than the subject.

• Where Systems Meet People: a technical decision that turns out to be a human one.
• Built and Broken: something actually built and tested, including the times it broke.
• Working Out Loud: a decision still in progress, with the outcome genuinely unknown.
• The Long Argument: a question that does not resolve quickly, revisited as my view changes.
• Field Notes: short dated observations, published while still unfinished.

These are closer to newspaper sections than to subjects. News, Op-Ed and Letters are not topics either. They tell you what kind of thing you are about to read.

How it gets made

Research and first drafts run through a set of AI agents. The scanning, the source gathering, the structure and the tagging are automated, and it would be dishonest to imply otherwise on a site whose first rule is calibrated honesty.

What is not automated is the part that decides whether any of this is worth reading. The firsthand experience behind a piece is mine. The claim drawn out of it is mine. The confidence marking is mine. Nothing publishes until I have personally confirmed those three things, every time. An agent can search and it can draft. It cannot have spent a Tuesday watching a deployment fail, and it does not get to pretend that it did.

What this is not

It is not news. It is not tutorials. It is not commentary on other people's product launches. If a piece does not rest on something actually done, built, managed or watched happening, it does not belong here.
