// COLOPHON / WHO & WHY

One writer, one desk, no recommendations.

Vercilo is a personal publication on AI, hardware, and the systems we build between them. No team, no sponsorships, no “what we're reading” — just essays, when they're done.

I write about the parts of computing that don't make it into the keynote.

Hello. I'm the editor of Vercilo — a small, slow, one-person publication about the seams of modern computing. The pieces too unfinished for a paper, too involved for a thread, and too specific for the front page of a tech blog.

I've spent the last decade somewhere between systems engineering and machine-learning research. I've shipped a database, two compilers I'm not proud of, and one model serving stack I am. I've reviewed papers, fixed memory leaks at 3 AM, and watched several “next big things” arrive on schedule and then quietly leave again.

Vercilo is where I publish what I learned in between — long arguments, mostly about why a thing works the way it does, and what would have to change for it to work differently.

Two essays a month, give or take. No newsletters-of-newsletters. No tracking. No discord. The contact details further down work; I read them.

What I'm working on, this month.

A standing “now” page in the Derek Sivers tradition. Updated when something material changes, not on a schedule.

Writing

Essay №35 — “Building for one is the new full-stack.”

A long piece on solo apps, the tooling shift behind them, and what they reveal about “team-shaped” software. Currently in the second draft.

Reading

Three papers on speculative decoding.

Still trying to convince myself the gains hold up outside the benchmark suite. Notes are accumulating in a folder titled, optimistically, maybe an essay.

Building

A tiny eval harness for Vercilo itself.

Lightweight tooling to grade my own drafts against a rubric I've been refining for two years. It is, very obviously, an excuse to not write the next essay.

// CV, lightly

A career in long arcs.

Names and titles are deliberately omitted; the work is the only part that aged well. Roughly chronological, most recent at top.

// editorial principles

How Vercilo is made.

The rules I write under. They're personal, not prescriptive — but every essay on this site has passed through them.

01

One author, one voice.

No ghostwriting, no editorial collective, no “contributors.” If a piece runs on Vercilo, I wrote it, and I stand behind it.

02

Slow, on purpose.

Essays land when they’re done — usually two a month, sometimes one, occasionally none. The cadence of thinking, not of publishing.

03

Models don’t write here.

I use language models for what they’re good at — research, line edits, code review. The prose, the argument, and the mistakes are mine.

04

Disclosed conflicts, always.

If I worked on a system I’m writing about, you’ll see it in the first paragraph. No hidden alignments.

05

Corrections live forever.

Every essay has a public changelog. When I’m wrong, the original stays up; the correction joins it.

// reach me

Letters welcome. Threads, less so.

I read every email. I reply to most of them, eventually. The best way to start a conversation is to send a long one — about something you read here, or something I should read.

// frequently, honestly, asked

Things people email about.

A short list of the questions that arrive most often, answered once so I can stop drafting the same reply.

01Will you take a sponsor / a guest post / a partnership?+

No, sorry. The site has no advertising and no commercial relationships, and I'd like to keep it that way for as long as it's mine to keep. If you want to support the work, the kindest thing is to read it and tell someone.

02Can I republish your essays / translate them / quote them?+

Yes — everything here is CC BY 4.0. Quote freely with attribution. For full reprints or translations, drop me a note first; I almost always say yes and I'll usually offer to review the translation.

03Do you take freelance / consulting work?+

Occasionally. I take a small number of advisory engagements per year — usually short, technical, and pre-product. I don't do retainers, fundraising decks, or general AI strategy. Email is the right way to ask.

04Will you come and speak at our event?+

Maybe. I do a handful of talks a year, usually in Europe and usually adjacent to an essay I'm already writing. I don't fly long-haul for keynotes. If your event is small and your audience is technical, please ask.

05How do you actually choose what to write about?+

I keep a folder of half-formed objections — things I read or saw that didn't sit right. When the same objection shows up three times in a quarter, it usually becomes an essay. The good ones argue with me for a few weeks before I argue back in public.

06Why “Vercilo”?+

It's a portmanteau I made up while looking for a domain that wasn't taken. Verso, the back side of a printed page — where footnotes and addenda live — and cilio, the small hairs on a cell that move things along. It scans nicely as a verb. That's the entire etymology; there is no clever second meaning.
