The proliferation of this quote is so interesting to me. It's often posted by right wing chuds who use it to defend conventional aesthetic ideas — such as the importance of having a lean, athletic body — but they don't really understand Owens's work. Let's talk about it. 🧵
A quote by Rick Owens. It reads: "Working out is modern couture. No outfit is going to make you look or feel as good as having a fit body. Buy less clothing and go to the gym instead."

It feels weird to see a former project I poured years of work in, go full AI slop. A bit sad, and it does not bring confidence in the production runs going forward

Fun fact : Par sa décision, le @conseil-etat.fr n'a pas seulement validé la liberté d'utiliser l'écriture inclusive. Il a aussi entériné ce que les juges administratifs ont retenu : Le fait que l'Académie française « se soit déclarée opposée à son usage » n'a... *aucune* incidence légale. (🤭)
3. Il ne résulte pas des dispositions précitées, ni d’aucun autre texte ou principe que la
graphie appelée « écriture inclusive », consistant à faire apparaître, autour d’un point médian,
l’existence des formes masculine et féminine d’un mot ne relève pas de la langue française. Les
circonstances que le ministre de l’éducation nationale ait proscrit son utilisation à l’école par
une circulaire du 5 mai 2021 ou que l’Académie française se soit déclarée opposée à son usage
dans une lettre ouverte du 7 mai 2021 restent à cet égard sans incidence sur la légalité de la
décision attaquée de la Ville de Paris.

This is what happens when you try to skip to an endgame factory in factorio
Excerpt from "now it can be told":
"
The piles themselves were surrounded by heavy shields of steel,
pressed wood and concrete, to protect the operators from the extreme
radioactivity that accompanies the formation of plutonium. The energy
of this radiation is cquivalent to that of hundreds of tons of radium,
Each pile was located within an area of one square mile. At first
they were six miles apart. S additional piles became necessary,
we planned to intersperse them between those already in existence, so
that the distance betwee them would then be three miles.

Design of the equipment for the chemical separation plants had to
i
keep abreast of, and in some cases ahead of, the development of the
process itself. Fortunately, the two separation processes that seemed
to offer the best prospects employed virtually the same equipment and
piping layouts, SO that it was possible to go ahead with a design the
first stages of which would be suitable for either process. Almost every
one of the major design decisions for Hanford had to be made before
the Clinton pile was in operation.

Oricinally eight separation plants were considered necessary, then
Six, then four. Finally, with the benefit Of the `perating experience
and information obtained from the Clinton semi-works, we decided
to build only three, of which two would operate and one would
serve as a reserve. I should like to point out that these separation
plants were designed when we only had sub-microscopic quantities
of plutonium. Here again, each plant was provided with its own water
system and steam plant and the other service facilities needed for
independent operation. Each plant was a continuous concrete struc-
ture about eisht hundred feet long, in which there were individual
cells containing the various parts involved n the process equipment.
To provide protection from the intense radioactivity, the cells were
surrounded by concrete walls seven feet thick and were covered by
six feet of concrete.

As someone who works on the interaction layer of software: it's this. Stupid trends in hardware self correct after a generation or two, but *software* ratchets in the direction of unusable because designers are occupied with interaction patterns and not whether the fucking thing works properly.

Sometimes I feel we got a little bit too comfortable with blameless postmortems. We should introduce the accountability premortem. If something can fail and it was predictable, somebody should put their neck on the line, either to prevent it or to deal with the consequences if they arise

A related thing I’ve seen is decent software folks saying “at least what I do isn’t critical” as a way to distance themselves from the perceived responsibility/stress/burden of the things we work on, knowing the tradeoffs we make. We’re given huge amounts of power and should act accordingly.

People forgot what happened to Enron and the Big 5. It's not exactly the same kind of creative accouting, but there's the general feeling of "I'll build this big thing, benefit from it, it won't bring down my books and somebody else will hold the bag"

Rolling out the Matt Christman quote from after Charlottesville (2017) again:
And that's what these guys are, these guys that marched in Charlottesville, these are the people who are aware of the unspoken premise of this sort of zombie neoliberalism that we're living in, which is that we're coming to a point where there's gonna be ecological catastrophe, and that it's gonna require either massive redistribution of the ill-gotten gains of the first world, or genocide.
And these are the first people who have basically said, "Well if that's the choice, then I choose genocide",
", and they're getting everyone else
ready, intellectually and emotionally, for why that's gonna be okay when it happens, why they're not really people. When we're putting all this money into more fucking walls and drones and bombs and guns to keep them away, so that we can watch them die with clear consciences, it's because we've been loaded with the ideology that these guys are now starting to express publicly.

Then again, me writing posts that an LLM can't reliably divine the intention of signals another problem.
Back in the 1980s, Yosemite National Park was having a serious problem with bears: They would wander into campgrounds and break into the garbage bins. This put both bears and people at risk. So the Park Service started installing armored garbage cans that were tricky to open —you had to swing a latch, align two bits of handle, that sort of thing. But it turns out it's actually quite tricky to get the design of these cans just right. Make it too complex and people can't get them open to put away their garbage in the first place. Said one park ranger,
"There is considerable overlap between the intelligence of the smartest bears and the dumbest tourists.

There is no difference in practice between removing rights of individuals and leaving the ECHR. The end outcome is still the same, people lose rights. If human rights are an obstacle to your policy it is not the rights which are the issue, it is your policy. Labour going full Reform at this stage.
She will also announce reforms to the application of key elements of the European Convention on Human Rights (ECHR), including article 8, the right to a family life. She is expected to raise the need for international reform of article 3, covering torture and inhuman and degrading treatment. Both have been blamed for hindering Britain’s ability to remove illegal migrants and failed asylum seekers.
