Almost 60 ghost estates remain two decades on from crash Nearly 20 years on from the financial crash, almost 60 ghost housing estates remain across Ireland.

Very pleased to speak to Eithne Dodd recently for this interesting piece from the This Week show revisiting ghost estates almost 20 years after the crash www.rte.ie/news/ireland...

A lot of common sense in this piece, with a key takeaway that we have to take the politics of housing seriously

Nothing sums up what’s wrong with our property system more than landscapes pockmarked with decay across #DerelictIreland. What many see as failure, Trinity’s Cian O’Callaghan shows can function as strategy.

Every one needs to watch and hear this testimony especially in the UK where the leaders of both far right parties have plans to introduce a version of ICE to the streets of Britain.

Regardless of what you think of the Triple Lock, the Government's efforts to remove it without a referendum is anti-democratic and flies in the face of any claims about 'reclaiming sovereignty' over foreign policy.

We're recruiting 2 PhD candidates in human geography here in Uppsala, one position focused on urban/housing issues and one in political ecology.

Please spread the word/repost etc. Being a PhD student in Sweden is a good gig.

Tulsa Sunday YouTube video by Lee Hazlewood - Topic

I finished watching The Lowdown recently, which id recommend. One of the enjoyable things about it is a great soundtrack, featuring a lot of Oklahoma musicians - I got introduced to this lovely piece of strangeness from Lee Hazlewood from a record I hadn’t heard before

[from the FT]
Trump explained his own interest in Greenland in 2021.

“So I’m in real estate. I look at a corner, I say, ‘I gotta get that store for the building that I’m building’ etc. You know it’s not that different. I love maps. And I always said, ‘Look at the size of this, it’s massive, and that should be part of the United States’. It’s not different from a real estate deal. It’s just a little bit larger, to put it mildly,” he told US journalists Susan Glasser and Peter Baker.

I'm sorry. As a technology writer, I'm supposed to be telling you that this bet will some day pay off, because one day we will have shoveled so many words into the word-guessing program that it wakes up and learns how to actually do the jobs it is failing spectacularly at today. This is a proposition akin to the idea that if we keep breeding horses to run faster and faster, one of them will give birth to a locomotive. Humans possess intelligence, and machines do not. The difference between a human and a word-guessing program isn't how many words the human knows.

I'm sorry. I know that when we talk about "digital sovereignty," we're obliged to talk about how we can build more data-centres that we can fill up with money-losing chips from American silicon monopolists in the hopes of destroying as many jobs as possible while blowing through our clean energy goals and enshittifying as much of our potable water as possible.

If one third of the housing stock was social housing we probably wouldn’t have half the housing problem we have. But it suits the far right (for obvious reasons) and the government (to detract from their policy failures) to inflate migration figures & their impact on housing. Fuelling misinformation

Great new paper which examines the somewhat ambiguous role that Approved Housing Bodies increasingly play in the Irish housing system

The protestors in Nepal were flying Straw Hit Pirates flags. Fandom is a much more powerful motivator than political theory these days because we exist in a realm of politics that is essentially a form of fandom. Sorry but Marx and Lenin are dead; long live Luffy and Luthen.

what you clearly see, CLEARLY, is a driver who is spooked by the agents grabbing her door, takes steps to drive away, and is immediately shot as moves her vehicle *away* from the agents.

My mother was a refugee of the Salvadoran civil war. The Americans backed the fascists that took over the country. Now Salvador is run by a pro yankee crypto dictator who has built the largest concentration camp in the western hemisphere. That, is American intervention.
