C'mon, that's surely an AI error - the churchy equivalent of messed up fingers.

Tories scrapped half of HS2, which without the other half would actually make many train times worse.

People said β€œwhy don’t you focus on electrification of existing lines then” so now Labour, eager to proven they’re different from Tories, have scrapped all of that too.

On the first point - does make sense. On the second - it's delivering the other jobs you have already lined up I was thinking about. I can certainly imagine the client wanting the demolition finished asap though.

Many possible reasons for that - eg the contractor has two excavators and operators, and they need them somewhere else soon.

I'm sorry, I didn't notice the two types! I was wondering whether one quarry had made a market. Guess it's just a thing people expect to find. Interesting speculation why Italy has that and we don't.

There seems to be a big deal about 'eco-bricks' made from stone in the UK..., meanwhile in Italy, almost every building supplies outlet sells these.

Are they all from the same source, or same principle different suppliers?

And the flip-side to the lintel that wants to pass as an arch is the hidden key. Where the limitations of the stone call for an arch, but the appearance of an arch is unwanted, we get an arch in denial, with flat soffit and apparently verticalβ€”not radialβ€”joints.

For thousands of years we’ve been building with trabeated stone. For thousands of years it’s been chewed at, chased to abstraction. Repeatedly exhumed and revived, even after Roman concrete, even after Gothic vaults, after Rundbogenstil and Candela’s shells. Keeps coming back from the dead.

And yes, getting past the random giant picture of three happy students laughing at a salad at the top of the course page counts as one of those swipes.

I’ve mulled over posting this for months now. But yesterday it came to a head. And I’m aware that the people who need to see it will either not be here, or will suggest that I’m lying.

I live near an asylum hotel. The reason I didn’t post earlier is that I didn’t want to raise undue attention

This is a thought provoking, bite sized little piece that boils down to, "don't give feedback on EVERYTHING, because not everything matters! give feedback on things that have impact."

I think it's a *great* exercise for the feedback-giver to think through the impact they want their advice to have.

Only 0.5% of 90,000 oil slicks reported over five-year period, analysis finds | Shipping industry | The Guardian Pollution incidents reported between 2014 and 2019 were compared against scientific study that used satellite imagery to count slicks

Imagine thinking wind turbines are ecocide where over five years fossil fuel tankers create 90,411 oil spills *and only bother to report 474 of them* - satellite analysis exposes high density "slick belts" coinciding with shipping lanes.

Two in five arrested for last summer’s UK riots had been reported for domestic abuse Police data indicates overlaps between public violent disorder and domestic violence and abuse

In "Legitimate Concerns" news.

41% of the 899 arrested for taking part in Farage Riots last year had been reported for crimes associated with intimate partner violence.

For those arrested by one police force, this figure was 68%.

Side on view of a packhorse bridge. Plenty of water flows under it. A clean arch of the bridge is centre shot. Trees and bushes give us the the edging of this picture.

From Riverside looking north towards the bridge. We see the very thin arch of the bridge scanning the water. A large tree comes into the foreground from left of shot.

Todays was this gorgeous Packhorse looking bridge along the fosse way.

A bridge widened. Underneath Laverock Bridge, Mealbank, Cumbria. The left side once good for pack horses but then cars were invented.

Heidi Alexander's decision to remove the safeguarding of HS2's route from Birmingham to Leeds is short-sighted in the extreme. This is the most beneficial part of the whole HS2 scheme - as we said at the time that the construction of the leg was cancelled. www.placeyorkshire.co.uk/govt-axes-de...

🧡Learning to build by taking things apart:

Some 19th c theorists like Viollet-le-Duc were fond of banging on about the structural and constructional logic of the Gothic style, terms that feel inappropriate when applied to elements that seem purely aesthetic, like the cusps & featherings of tracery.
