Celestial Sphere: An itemized personal computing environment

October 14 · Members only

Members - I have a demo and lab report to share with you today.

It’s about an environment that I’ve been living in for several months. It came about somewhat unintentionally, but has grown to reify the kind of personal computing I’ve been in search of for many years.

Our next title, Augment

June 23

I have some news to share with you today: we’ve announced our next title, and opened a call for submissions. Consider contributing, and if someone you know might be a good fit, please send this their way!

You may recall that last year Sarah and I started an indie press. We published our first title, a book about how computers work, and have since produced more than five hundred handmade clothbound editions, as well as many more paperbacks. Now, we’re preparing our next title.

Augment is a forthcoming book featuring essays by various authors about the future of personal computing and the ideas we’ll need to keep in mind as we build it. Confirmed authors include Alan Kay, Ben Fry, and Alex McDowell. The book will be co-edited by John Underkoffler and myself.

Though many likely will, contributions do not need to come from the field of computing itself. We hope by sharing the call for submissions broadly, we might attract essays from experts in many disciplines. What lessons, ideas, perspectives, and processes could our field learn from architecture, anthropology, cosmology, urban design, civil engineering, film and music production, and so on?

Submissions will be open through the end of August. We hope you’ll share this with those you think might write a great chapter, and even consider writing one yourself.

Finally, an update on Bootstrapping Computing: we have a few more first edition paperbacks available, and will have a new print run of the handmade clothbounds later this year. Each one takes several hours to make; we’re working hard toward the next release - stay tuned!

Cheers!

Architecting the user environment of an itemized OS

December 3, 2025 · Members only

In a new lab report I published today, I’m exploring one way to look at the architecture for the itemized user environment: a layering that has been happening since the dawn of time.

It explores a number of things I’ve been thinking about more this year. I hope you enjoy it:

Things I'm working on lately

November 20, 2025

Lots to share with you from 2025…

First, the paperback of my book, Bootstrapping Computing, is available for preorder now, and will be released on December 1! Here’s a quick summary:

The book is about how ten layers, starting from binary, were arranged to build up to personal computing and the World Wide Web. Each layer is built out of the simpler parts of the one below, arranged to produce increasingly sophisticated ideas of what computing could be. It’s an incredible story of human ingenuity.

The paperback’s cover features a beautiful original illustration by Owen D. Pomery, and the entire book is printed in full color.

Grab a copy for yourself or a friend this holiday season - I hope you enjoy it!


Some recent work in this section, and some personal updates in the two that follow:

A few weeks back, I published a second part to The Interfaces With Which We Think. It’s about the moral imperative for composable systems and malleable software.

Earlier this year, I recreated the user environment found on the Canon Cat, a 1987 follow-up to the Macintosh by Jef Raskin. This was a really wild idea of personal computing: the entire OS’ user environment was, essentially, one long document.

I explored its implications after living in the environment for about a week in a lab report on my member site, now made publicly available. I also published my recreation for you to try out there.

There’s another member essay I made publicly available observing the process by which my work happens.

Most recently, I’ve been working on an itemized user environment to live in full-time — the kind I’d want to see on a full implementation of an OS with the kinds of ideas envisioned in my lab notes and experiments over the last few years. In new lab reports for members, I’ve published deep dives into the system’s data model and filesystem replacement and the system’s language. The next update, out soon, will discuss the approach to designing the system’s architecture, and from there, we’ll head into the interface.

This has been the fullest implementation I’ve approached yet. It has taken years of experiments to fully understand a lot of the little details that would snag attempts in the past. I’m cautiously optimistic about this build.


This year has brought lots of change. Sarah and I started Buddy Bindery & Press — I wrote some on our first year in business here — and we moved to New Hampshire. When the bindery outgrew our existing space, we started looking for a new one. We also wanted to get closer to Boston, where Sarah’s in grad school.

We found a lovely ten acre homestead in the mountains, heated by a lone wood stove in the middle of the cabin. Lately, my days start around five or six in the morning at the wood stove, getting the morning fire going to break the night’s chill. Usually with a coffee in hand, and always with the cats overseeing the work. Then I get into making the days books, or some research and reading.

Between all the bookbinding, as well as all the wood stacking, splitting, and other such tasks, I’ve had a lot more time for audiobooks this year. I’m currently in the middle of On the Origin of Time, which is turning out to be my favorite new read of the year. It does an excellent job of describing both how certain ideas work, as well as how their fomenters meandered into them. And when those ideas are the time dimension and a spatial dimension kind of switch roles inside of black holes, things get interesting fast.

This was also done quite well by the book on Bell Labs, The Idea Factory. (My only complaint with that book — and it’s a big one — is that, of all the ideas it helps you understand the formation of, Unix is given only a passing mention in a fraction of a sentence.) Tim Berners-Lee’s Weaving The Web also does a great job of this, helping you get into his headspace when he dreamt up all of the necessary peculiarities that became the Web.

I love this kind of book: help me to understand a wild idea, and how people thought such a thing up. My hope was to do just this with my book — I hope it delivers. Dealers of Lightning, on Xerox PARC, is a good counter-example: it does neither, instead mostly flogging middle management’s various politics for missing out on some of the biggest inventions of our age — not terribly interesting reading, unless you’re a manager in need of yet another cautionary tale. It glosses over the many wondrous ideas that came out of PARC and how they were hatched by the many figures now of computing lore.


The publishing company and bindery has been a wonderful source of surprises and problems to solve. Besides writing and designing our first book, I decided to hand-make the hardcover edition.

I’m not sure why, but I thought we’d get 20 orders. I would have been stoked with that! Sarah thought it’d be more like 50. We were both wrong. We eventually sold 350 before we had to turn the thing off so I could catch up.

We had to get lots more supplies, but at some point in the process, the paper we were using was discontinued by the manufacturer. So we spent some weeks hunting down the last remaining reams at paper suppliers around the country.

Making so many books by hand has been therapeutic. It’s even helped me enjoy my computer work more. I think there’s some forced balance there that I need. Back when we lived in an RV, I had this in spades: every day required some various tasks on the rig, and a couple drives a week through evolving North American landscapes helped keep my head in the right place. But without this kind of balance, I tend to go too deep into my work on the computer, without any benefit to me or the work.

So with that in mind, I’ll log off, and get to the books.

I hope all is well in your part of the world.
– Alex

A programming language for the itemized user environment

September 17, 2025 · Members only

In the last lab report, we kicked off a series exploring the itemized user environment that I’ve been building this year. It’s the latest in my experiments on the future of personal computing, and it’s the most exhaustive one so far.

The environment’s programming language is the subject of today’s lab report — it includes a demo, discussion of the features that help with handling items and item views, and explores how its own architecture can support a prospective itemized IDE.

Implementing the data model for an itemized user environment

August 28, 2025 · Members only

This year, I’ve been hard at work building a user environment that reifies personal computing of the kind I’ve explored for the last several years — something I can fully live in.

Over the next several lab reports, we’re going to take a deep dive into this environment and its implementation, as well as a bit of the project’s philosophy. This first report is on the environment’s storage mechanism. The next one will cover the environment’s programming language. After that, we’ll move toward the environment’s interface.

Reimplementing the Canon Cat document interface

March 26, 2025 · Members only

Hello members,

First, some quick housekeeping: This membership program is run through my LLC, which has been renamed Obenauer Studiorum (it used to be Mindsense LLC). You will see either the new name or “Little Lab Membership” on your bank statements going forward.

Now, onto today’s update: I’ve spent some time living in a recreation of the Canon Cat from 1987 which featured a user environment that was one long document. In this essay, I’ll share some observations with you, along with a demo video. You can also try out the recreated environment for yourself.

I wrote a book!

February 1, 2025

I have two things to share with you today:

First, we’re starting a publishing company.

Second, I wrote a book about computing, out soon.


Let’s start with the book:

I’ve had a bunch of versions of the same conversation with curious friends and family over the years: folks are generally aware that computers “use binary”, but want to understand how they build up from there to all the things we recognize as modern computing today. This book answers that question.

Over ten chapters, it illustrates how we built each layer of computing out of the one before, and the models of thinking that got us there. It’s a short, technical book for curious, non-technical people.

It’s called Bootstrapping Computing, and I’d love for you to have a copy, share one with your most curious friend, and enjoy these wonder machines before us a little more with me. While it’s written for a non-technical audience, I’ve greatly enjoyed how it has helped me solidify my thinking about the fundamentals of computing; the ingredients for my everyday work.

Each book is archival quality and made by hand in Tennessee. The cover is a hard case wrapped in smoke grey book cloth, and the 112 pages are printed in full color using pigment-based ink on 80 lb warm white paper sewn with accented linen thread.

It comes out at the end of March, and you can preorder now.

Now, the publishing company I am starting with Sarah, my wife:

We care a great deal about books. But most of the books coming out today aren’t that good — in content and construction. Too many would be better as shorter books, but include lots of filler. And too many are just poorly made, and don’t stand the test of time.

Authors don’t have many great choices. Self-publishers are pushed to use print-on-demand services, which have mixed quality. Or when working with a publisher, authors have to give up lots of quality and control to fit that publisher’s idea of a good book, and leave all of the most interesting decisions about the construction of the book to what would be produced the cheapest.

We want to help build “the ninth path” for today’s authors and readers. Our company is building all of its own books in-house. They are archival quality, handmade using the best materials and methods. Folding, sewing, gluing, cutting, casing-in, pressing — it’s all done by hand. If well-cared-for, these books will last generations.

We’re starting by publishing some of our own works, and if things go well, we will move into publishing books by other authors.

And honestly, I’m most excited to be working with Sarah again. We do some of our best work together, and making books together has already been a dream come true. We hope you’ll pick up a copy of our first book, and sign up to hear about our new releases.

There’s nothing quite like a really nice, physical book that anchors your personal library, the kind that you leave on your desk for days or weeks after you’ve read it — having the words dutifully cared for and brought to you in a beautiful, tactile physical construction — it’s one of my favorite things in the world.

I’m looking forward to learning what it takes to make great books, and making them for you.

— Alexander

A tour of our websites and research notebooks

November 22, 2024 · Members only

Hello members!

Last time, I sent you a member’s update with explorations surrounding the OS’ graphics stack, and I sent it to you in the new member’s site.

Today, we’re exploring that site, among others, as well as our research notebooks, in something of a “behind-the-scenes” tour. It touches on design and development, with links to everything we use, and thoughts on what’s new in the stack.
