Taco night has become a weekly occasion in our house – something all ages and palates can get on board with.We like to switch up the protein depending on the season and our cravings, but this is our current vegetarian favourite.It’s not traditional by any means, but a wonderful way to get a rainbow of veg into our diets.The cubes of halloumi are joyful when roasted, as are the pops of toasted spiced pumpkin seeds.You could even drizzle them with a little honey for the last couple of minutes of cooking, leaning into a salty-spicy-sweet finish.

Prep 10 min Cook 30 min Serves 4400g butternut squash, peeled and chopped into 2½cm cubes1 tbsp Cajun spice blendOlive oil Sea salt and black pepper 50g pumpkin seeds 150g halloumi, cut into 2cm cubes8 small corn or wheat tortillas1 red onion, peeled and very finely chopped2 limes 2 green chillies ½ bunch fresh coriander, chopped2 avocados Soured cream, to serve (optional)Heat the oven to 240C (220C fan)/475F/gas 9.Put the chopped squash in a large roasting tray, toss with the Cajun spice blend and three tablespoons of olive oil, and season generously.Roast for 20 minutes, stirring in the pumpkin seeds halfway through.After the squash has had 20 minutes, add the chopped halloumi to the tray and return to the oven for five to seven minutes, until everything is slightly charred.Wrap the stack of tortillas in foil and put the package in the oven to warm through.

(You can also char them for 10 seconds over an open flame, to give them a nice edge.)Meanwhile, mix the finely chopped red onion, the juice of one and a half limes and a pinch of salt and some black pepper in a bowl.Finely slice the green chillies (deseed them if you don’t want too much heat) and add most of them to the bowl, along with most of the chopped coriander.Halve the avocados and use a spoon to scoop out the flesh on to a chopping board.Cut into small cubes and add to the onion bowl with a drizzle of olive oil.

Gently mix to combine, then taste and adjust the seasoning.Put the bowl in the middle of the table with the soured cream, remaining chopped coriander and chilli, and the remaining lime cut into quarters.Transfer the squash mix to a serving bowl and take it to the table with the warmed tortillas.Let everyone make their own tacos: a spoon of charred squash and halloumi topped with punchy avocado salsa, a little soured cream, if using, and garnish with the remaining sliced chilli and chopped coriander.Heaven.

New datacentres risk doubling Great Britain’s electricity use, regulator says

The amount of power being sought by new datacentre projects in Great Britain would exceed the national current peak electricity consumption, according to an industry watchdog.Ofgem said about 140 proposed datacentre schemes, driven by use of artificial intelligence, could require 50 gigawatts of electricity – 5GW more than the country’s current peak demand.The figure was revealed in an Ofgem consultation on demand for new connections to the power grid. It pointed to a “surge in demand” for connection applications between November 2024 and June last year, with a significant number coming from datacentres. This has exceeded even the most ambitious forecasts

Palantir deals are a threat to our data rights as UK citizens | Letters

For 100 years, the UK government has led us through existential threats, including two world wars. But instead of resisting the latest threat to democratic accountability, it has welcomed it with open arms: Palantir Technologies (NHS deal with AI firm Palantir called into question after officials’ concerns revealed, 12 February).This polarising US surveillance giant provides data-fusion and AI platforms used by by the US for immigration enforcement and by Israel in the Gaza conflict. Its software amplifies state power through militarised analytics and opaque algorithms.The current government hasn’t just surrendered citizens’ data rights to Palantir – it has paid for the privilege

Sam Altman defends AI’s energy toll by saying it also takes a lot to ‘train a human’

The OpenAI boss, Sam Altman, has tried to ease concerns about how much power is used by artificial intelligence models by comparing it to the amount of energy required by human development.“People talk about how much energy it takes to train an AI model – but it also takes a lot of energy to train a human,” Altman told the Indian Express recently while in India for the AI Impact summit. “It takes about 20 years of life – and all the food you consume during that time – before you become smart.”Despite that defense, he said that the public assessment of AI’s energy consumption was “fair”, adding: “We need to move towards nuclear or wind and solar very quickly.”Those remarks come amid growing discussion about the environmental impact of the datacenters required to power AI models – and, more generally, about technology’s possible impact on society

US farmers are rejecting multimillion-dollar datacenter bids for their land: ‘I’m not for sale’

When two men knocked on Ida Huddleston’s door last May, they carried a contract worth more than $33m in exchange for the Kentucky farm that had fed her family for centuries.According to Huddleston, the men’s client, an unnamed “Fortune 100 company”, sought her 650 acres (260 hectares) in Mason county for an unspecified industrial development. Finding out any more would require signing a non-disclosure agreement.More than a dozen of her neighbors received the same knock. Searching public records for answers, they discovered that a new customer had applied for a 2

Amazon’s cloud ‘hit by two outages caused by AI tools last year’

Amazon’s huge cloud computing arm reportedly experienced at least two outages caused by its own artificial intelligence tools, raising questions about the company’s embrace of AI as it lays off human employees.A 13-hour interruption to Amazon Web Services’ (AWS) operations in December was caused by an AI agent, Kiro, autonomously choosing to “delete and then recreate” a part of its environment, the Financial Times reported.AWS, which provides vital infrastructure for much of the internet, suffered several outages last year.One incident, in October, downed dozens of sites for hours and prompted discussion over the concentration of online services on infrastructure owned by a few massive companies. AWS has won 189 UK government contracts worth £1
