I am experimenting with pulling more social media content directly into these digests, in part to rely less on social media sites long-term (since content might be deleted, blocked, paywalled, etc.) That makes these digests longer, but it means there is less need to click on links.

I will still link back to original social media posts in order to give credit and make sharing easier. As always, let me know your feedback.




  • Adobe co-founder John Warnock, 82. Steven Sinofsky calls him an “industry and technology legend… from Xerox through decades after co-founding Adobe he changed the technology landscape we all benefit from every day.” John Gruber says: “Warnock and Geschke understood what Steve Jobs often preached: technology alone was not enough. … If Warnock and Geschke had been satisfied merely with shipping great technology alone, Adobe Systems would be a nearly forgotten Silicon Valley footnote. Instead, they pushed to make Adobe the great tool-making product company we know today.”

Mises against stability (Masters of the Universe, by Daniel Stedman Jones):

Like Popper, Mises saw a similarity between the bureaucratic mentality and Plato’s utopia, in which the large majority of the ruled served the rulers. He thought that “all later utopians who shaped the blueprints of their earthly paradises according to Plato’s example in the same way believed in the immutability of human affairs.” He went on, Bureaucratization is necessarily rigid because it involves the observation of established rules and practices. But in social life rigidity amounts to petrification and death. It is a very significant fact that stability and security are the most cherished slogans of present-day “reformers.” If primitive men had adopted the principle of stability, they would long since have been wiped out by beasts of prey and microbes.

“Comment posted to a NY Times article published 3 years ago during lockdown, questioning whether NYC would ever recover” (via @michaelmiraflor):

I’ve been a NYC taxi driver for many, many years. My favorite type of ride is the rare one of picking up a man who has just emerged from a hospital following the birth of his first child. It is the best day in his life and I usually find it difficult to hide my own tears of joy as he tells me all about it.

My second favorite ride is similar. It is a young person with a dream who is coming to New York City for the very first time. I am the taxi driver taking him or her to Manhattan from the airport. I insist on the Upper Level of the 59th Street Bridge as our route. Excitement grows as the city grows larger and larger as we approach Manhattan. Finally, almost at ground level, the ramp takes us so close to the surrounding buildings that we can actually see the people inside. Touching down on E. 62nd Street, my newly minted New Yorker is experiencing for the first time the “energy” that is so often spoken of. It’s like watching a child approaching a roomful of birthday presents. All things are possible.

“For thousands of years, city planning focused on drawing out a street network, with water and sewer underneath, and reserving regular public spaces, and was mostly agnostic on uses or densities. One hundred years ago, that flipped”

The idea that city planning was doing sewer planning for thousands of years is just wrong. Historically there was no such city planning for most of the time. 

Berlin, Paris, and London all only got their sewer systems in the 19th century. 

I don't think this is exactly correct: I'm pretty sure that many cities including London and Paris had sewer systems much earlier than that, although they modernized them / made major overhauls in the 19th century. (Anyway, kind of besides the point of the linked thread)

There is a claim that there was city planning for thousands of years. 

If you ignore the issue of streets and look at older parts of many European towns the streets aren't straight because nobody planned them beforehand and they grew more organically.

What happened in the 19th century in Europe was that people actually started city planning. American cities might have a drawn-out street network before that point but in most European cities there wasn't planning. 

Norway can build a tunnel for lower cost than it takes Britain just to do the planning application for one, and many other damning facts from @Sam Marks 

Especially, given that the supposed reason for leaving the EU was to escape Brussels bureaucracy.
