Very happy to finally see this in the flesh today: the remains of an early tenth-century calendar from LandΓ©vennec, Brittany, whose entry for the year 913 contains an annotation that the local coastal monastery of Winwaloe was attacked by vikings during that year.

Reform will apparently pledge today that they'd abolish indefinite leave to remain - including retrospectively, to people already granted it. Obviously this is a moral abomination but it is also a practical and legal impossibility.

Some people argue that 'the British Isles' isn't political and we shouldn't be bothered by it, which is why they're invariably so open to my suggestion that we should switch to 'the Irish Isles' for the next few hundred years while we work out a solution.

I've never really used LinkedIn, as it was always a very privacy-averse place, but they'll now also be hoovering up your personal data to train GenAI models (as per their new T&Cs). The fact that this is opt-out rather than opt-in speaks volumes.

Today's vikingism: the widely popular 'Immigrant Song', from Led Zeppelin's third studio album (III), released in late 1970. Its lyrics famously reference themes from Norse mythology and describe viking groups journeying overseas ('from the land of the ice and snow').
