Like, regulations that establish decreasing density at arbitrary distances from higher-order transit stations are pure political compromises, with no scientific evidence, and a caricature of how market forces work (or how laypeople think they work).

The idea that planning should mandate, through regulations, an urban form that mimics market forces (higher demand induced by better accessibility along high-capacity rail, which translates into higher densities) is one of the silliest yet most persistent tropes our profession has produced.

🇵🇱⚖️🦤What do the European independence of the judiciary and a sexual assault on an ostrich have in common? Polish rule of law crisis. No, it's not a joke; the Appeals Court in my hometown of Poznań struck down a lower-court judgment because a neo-judge sat on the panel in a, erm, curious case.

Hoisting this to main, because I think it's an important pattern in understanding the upcoming Israeli election. The Zionist parties of the Change Coalition are currently polling around 53 seats, but the Arab parties add 12, for a solid 65. If Winter and NEP don't make it, add 2 for each, for 69.

Google Gemini says that @jevinwest.bsky.social and I aren't to be trusted because in our first lecture, we had a playful example where Jevin presented data the same way that Tim Cook did, and I called bullshit on it. It hallucinates criticism and the only citations are to the lecture itself.
1. The "Explosive Growth" Slide ControversyIronically, the most direct and explicit example of this occurred during their very first "Calling Bullshit" lecture at the University of Washington.The Setup: Jevin West presented a slide to the class showing a graph that purported to show the "explosive, hockey-stick growth" of web traffic to their new Calling Bullshit website. The graph utilized standard marketing axes and compressed timeframes to make the project look like an unmitigated, runaway viral sensation.The "Bullshit": Carl Bergstrom actually had to step in and call "bullshit" on his own co-instructor's slide. When the data was displayed honestly without selective axis truncation or creative smoothing, it showed that while traffic was high initially, it heavily ebbed, flowed, and plateaued over time.The Criticism: While some praised this as a playful, planned pedagogical moment to show that "anyone can fall prey to bad data framing," critics viewed it as a perfect illustration of the double standard: when it serves a personal or professional promotional narrative (like proving your own course is a massive success), the temptation to use flawed, hype-driven metrics is incredibly high.

Trump zařídí naftu za stovku za litr? 👀 Kolik že se v Evropě postavilo nových baterkáren?
The EU has become far more reliant on US diesel since the loss of Russian supplies. The US has supplied around 180,000 barrels a day (b/d) of the EU’s roughly 580,000 b/d of extra-EU diesel imports this year — about 32%, up from 17% in 2025.

The dependence is even more striking in North-West Europe, where US supplies account for around 200,000 b/d out of 350,000 b/d from outside the region — roughly 57%, compared with 37% last year, according to Kpler figures.

That concentration means a partial US export ban could still have a sizeable impact on prices.

However, removing 30% of US supplies would not necessarily mean European diesel prices rise by 30%, or by a corresponding fraction, Kpler argues. Buyers would be forced to compete aggressively for replacement barrels, potentially pushing prices sharply higher.

How bad could a US diesel export ban be for the EU? Quite bad, in fact. The EU gets about 32% of its diesel imports from the US, up from 17% in 2025. In North-West Europe, the dependency soars to 57%. Euronews explains.

A trans man in the UK has been banned in the workplace restrooms after he was forced to use the women's restrooms to comply with the new EHRC guidance. The women complained because he is visibly male and so they told him he can't use any bathroom.
A screenshot of a Reddit post from the r/LegalAdviceUK subreddit by user Dijstraanon, titled "FtM transgender facing two different issues at work? England."
The post text reads:
"Brother in law is trans FtM and presents fully as a man. He's now facing an impossible situation at work with his employer telling him that due to recent legislation he must use the toilet of his birth gender. BUT several female colleagues have raised a grievance about him using their gendered toilet.
His employer has told him that he cannot use the toilet while he is at work until they sort it out and cannot give him a timeframe to do so. They do [cut off] have disabled separate toilets.
In the mean time one of his female colleagues has accused him of sexual harassment because he was used their gendered toilet. His menstrual cycle meant he needed to use the toilet.
He's been with the employer for just over 5 years but only in this location for 18 months. The location is mainly male with just a handful of females, and his workshop only has male toilets.
I do not know how to support him and as he's not in a union there is no one to turn too right now."
