A century before we would move from fixed-program computers to reprogrammable ones, Ada Lovelace realized that the Analytical Engine was capable of universal computation. Reading her Notes is thrilling for her awestruck articulation of these ideas. Available now; link in reply.

Over the last several months, we've been working on a new, physical version of Ada Lovelace’s notes. This project was a lot of work, and a lot of fun.

Something I haven't gotten to say in a while... new lab note today! It's on a kind of user interface that pops up only occasionally: the extemporaneous UI that allows users to 'wave their wand' & get the interface they need through direct interaction. Read on: alexanderobenauer.com/labnotes/041/

LN 041: Extemporaneous UIs
Tear-off menus, quantized semantic zoom, and spatial computational canvases show us one approach to frictionless malleable interfaces.

We also have a "proposals" form if you'd like to get feedback on your idea before a full submission. Some wonderful submissions have already filtered in that way! And we have a "nominations" form if you'd like to submit a prompt for someone - a good prompt can be a wonderful gift.

Today, I'm excited to announce our next title! "Augment" is a forthcoming book featuring a collection of essays on the future of personal computing — specifically, on the kind we’d like to see more of in the future, and the ideas that might help us get there.
Augment is a forthcoming collection of essays on the future of personal computing: specifically, on the kind we as a species need in order to move beyond our stuck present, and on the ideas that will help us get there. This book is meant to serve as guidance and inspiration as we build a next generation of hardware, software, and systems.

We hope you’ll share this page with those you think might write great essays for Augment, and even consider writing one yourself. Submissions are due by July 31.

The technology field is today in a precarious state. A tsunamic tide of commercial thinking has managed the wholesale capture of practitioners, institutions, and dialogue. This capture has drained all imagination from our surround, and so actual invention has slid likewise near to zero. Along the way, the systems meant first to extend human reach have instead become dull and clanking manacles.

Yet the same quality that makes technology easy to hijack — that massless, abstract ductility — leaves it as easy to re-form. The opportunity is still with us, undimmed, to build anew the beautiful thing, the powerful thing, the luminous thing, the human thing. This then is the invitation: to trawl a net through waters that, far enough down, remain idea-rich and that, with care, might still teem.

If you read Bootstrapping Computing, what questions did you walk away from it with? Did you look anything up while reading it? Anything in it you could do without, or that served only to confuse?

We had to say goodbye to my grandpa this week. (He had a big influence on me. Least importantly, but most tangibly, if it weren't for him I might not be in software.) My sister wrote a beautiful article about him, it's a lovely exploration of a person: britobenauer.substack.com/p/my-grandpa...

I had no preparation for the phase of life during which loved ones are passing away regularly. I'm not sure what that preparation might have been, but I still feel utterly unequipped.

Some personal news: Sarah and I (and Cheesesteak) moved to Boston earlier this year. We've fallen more in love with the city since Sarah started grad school here a couple years back. Looking for a space for Buddy Bindery & Press; and looking forward to meeting who's around!

Great read from @alexanderobenauer.com 🙌 "...plenty of things let you explore someone else's thinking, but personal computers can help you explore your own thinking, giving you living spaces to externalize, review, expand, and refine your thoughts on the things that matter most to you."

We engage in an evolutionary construction that continues a tradition started by our physical world long before we were here, and carried on into computing from its earliest days. It's also a process that mirrors how creative, explorative work is done.
LAYERING UP THE ITEMIZED USER ENVIRONMENT
December 3

In this lab report, we consider one way to look at the architecture for the itemized user environment: a layering that has been happening since the dawn of time.

Some harbor an inclination toward a “grand design” in the construction of a new operating system’s user environment; a sort of “turtles all the way down” architecture that features one substance, or one core primitive, which defines the mechanics of an entire computing system deep under the hood and up into userland.

I’m more inclined toward the “layers” which we’ve been stacking up since we first made the jump from hard-coded circuits to programmable, general ones (and on which we have built many new layers — machine code, assembly, low- and high-level programming languages, and so on).

Each layer adheres to the contract of the one below, and offers a new way to think about things to the layers which will be built above. This is how we’ve bootstrapped into all of modern computing starting from simple logic gates, in a slow, evolutionary construction.

This isn’t just the way modern computing came to be; it’s the way our physical world came to be, too! This “layering” is how our world has evolved into the one we know. But it comes with some important consequences.Our evolutionary construction, the layering, neatly reflects how we do this kind of creative, exploratory work, and how the mind engages with ideas. Ted Nelson, in Literary Machines:

Complicated ideas evolve slowly. People who do not work endlessly with ideas may not easily imagine how many are the steps that intensive work with ideas entails; how many are the guesses, postulations, reconsiderations, shifts of thought, confusions, resyntheses, reintegrations; how much is the rework of dearly-held insights in clouds of confusion. The swirl of needed changes never seems to end. […]

This could not have been done with schedules and deadlines. When a project requires both exhaustive exploration and unusual inspiration, it is going to take however long it takes.

"I mistook a clear view for a short distance." Too real! I've experienced this time and again. But I'm reticent to encode a reminder to avoid this mistake in the future; my life has been filled with wonderful projects that I would not have embarked on had I not been so naive.

We had a lot of fun thinking about this cover, but one of my favorite things when working with artists is to just let them go wild with something they want to create. That's what we did here, and Owen knocked it out of the park. Love his choices of color, scene, etc.

It can be hard to discern and communicate why you're so drawn to some work. You're circling around something, but you're not sure what. By your nature, you hold some principle that is in conflict with reality; you can see yourself circling around it.

"A knife can cut an avocado, and much more." These kinds of sentences show up in the most fundamental papers that I return to year after year. They sound silly out of place, but in my favorite works, they're used to build up to essential guiding ideas and insights!
