Having agents make phone calls to (eg) restaurants a loss. It exposes a lack of an API. Restos will be overwhelmed and buy agents to handle the calls. Two giant software stacks will churn taking OOM more time and energy to imprecisely do what an API call could have nailed. ↵

Looking for a senior engineer who wants to own problems and ship end-to-end, product-minded or platform-minded, both work. Ping me if you want to chat about the role or recommend someone. Thanks!

We're hiring at Infinity Loop. We're building a negotiation intelligence platform for procurement teams: customers hand us their vendor contracts, and we turn them into renewal plans, negotiation playbooks, and budget forecasts, with human analysts augmented by AI.

The black box abstraction is how we protect what we do not control. The reflective abstraction is how we grow what we do.

SICP is also full of it. Unsurprisingly, since they endorse "procedural epistemology" at the beginning.

Well known idea for good programmers (verbs over nouns) but this is interesting to see the concept explained more formally.

Jean Piaget for programmers: "Empirical abstractions concern observables and reflective abstractions concern coordinations." Noun-abstraction generalizes what things are; verb-abstraction generalizes what you do. Only the second creates something new.

I think this is a big gap in software design culture. There's lots of commentary on visual design and micro-interaction, but remarkably little explicating conceptual and structural design. This section from Magic Ink is lodged in my mind. buff.ly/Bl9JwTv

Unsurprising common pitfall w/ Claude. Paying too much attention to what is instead of what ought to be. "Yes — that's exactly the right model, and your restructuring is what makes the 'problem' I raised disappear. It was never inherent; it was an artifact of how the current code is structured."

LLMs make it easier to both: - write less rigorous software - write more rigorous software than before. Both are valuable. It’s a fatal mistake to be confused about which mode you want to be in.

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.

Also, this Brian Eno quote has been really stuck in my head for weeks: "The great benefit of computer sequencers is that they remove the issue of skill, and replace it with the issue of judgement. ... the question then is, "Of all the things you can now do, which do you choose to do?""
The great benefit of computer sequencers is that they remove the issue of skill, and replace it with the issue of judgement.

With Cubase or Photoshop, anybody can actually do anything, and you can make stuff that sounds very much like stuff you’d hear on the radio, or looks very much like anything you see in magazines.

So the question becomes not whether you can do it or not, because any drudge can do it if they’re prepared to sit in front of the computer for a few days, the question then is, "Of all the things you can now do, which do you choose to do? "

The American Federation of Government Employees, which represents border patrol officers at the National Border Patrol Council, calls on Kristi Noem and Stephen Miller to resign or be fired
Following the killing of AFGE Member Alex Pretti and the subsequent slanderous rhetoric that followed from top Trump administration officials, AFGE National President Everett Kelley issued the following statement:

“Yesterday, AFGE brought together labor and faith leaders from Minneapolis and across the nation to mourn our fallen brother from Local 3669, Alex Pretti. We honored his life and legacy and lifted up his family, his friends, his union, Minneapolis, and our nation in prayer.

“Today, we demand accountability.

“In the immediate aftermath of Alex’s killing, DHS Secretary Kristi Noem betrayed the public trust by slandering the good name of our union brother and calling him a “domestic terrorist.” Alex Pretti was a patriotic ICU nurse at a VA hospital who devoted his life to serving America’s veterans. That claim was reckless, defamatory, and unsupported by the facts. Noem was preceded in this false statement by Stephen Miller, Deputy White House Chief of Staff, who is also the architect of the chaotic and failed immigration policy in Minnesota.

“Our demand is clear: Department of Homeland Security Secretary Kristi Noem, who was responsible for carrying out the policy that led to Alex’s needless killing, and Deputy White House Chief of Staff Stephen Miller, the architect of that policy, must resign immediately. If they refuse, President Trump must dismiss them.

Miller should be the target of Dem pressure. Yes, defund ICE, impeach Noem, sure. But if you want maximum change on the admin's behavior, focus on getting Miller out of day-to-day decisions. Drive a wedge by making him embarassing. Trump loves to blame someone else: make Miller the scapegoat.

I had very good experiences rapidly prototyping UIs with Claude. For production code I still have to rewrite/refactor it because it has a tendency not to refactor when iterating on the design and it often ends up with a convoluted mess.
