There’s a swimming pool in Devon getting heated by, essentially, other people’s AI homework. A startup called Deep Green installs washing machine sized data centers at leisure centers, submerges the servers in oil to capture the heat, and pipes it into the pool. The water stays around 30°C most of the time, the company refunds the electricity bill, and seven more pools in England have signed up. Somewhere, a neural net is moonlighting as a pilot light.

I’ve spent the past month reading headlines about data centers doing the opposite of this: driving up ratepayer bills, forcing utilities to build gas plants nobody wanted, and (today) warning that a new wave of them will spike Pennsylvania’s climate pollution. So it’s good, for once, to read about a data center’s exhaust heat helping the people standing next to it instead of costing them something. The waste has always been there. Someone finally piped it somewhere a kid could swim in it.

Meanwhile Uniqlo is selling a t-shirt with a working bash script printed on the back, an Akamai promotion that spits out a peace message if you actually type it into a terminal. A content delivery network put an executable on cotton. I don’t know what to do with that except enjoy it.

For the record: the Iran ceasefire I called fragile on Monday is now, per the White House, simply over, with strikes threatened again for Wednesday. NATO’s summit turned into a fight about Greenland, with Denmark announcing it’s “ready to defend” territory nobody has invaded yet. Against all that, Delta rolled out a “basic business” fare this week: business class, minus the lounge, minus your choice of seat. Apparently there’s no floor capitalism won’t find a way to lower.
