ScienceAlert: Quantum Computing Heats Up: Scientists Achieve Qubit Function Above 1K
Our new research may offer a way forward. We have demonstrated that a particular kind of qubit – one made with a quantum dot printed with metal electrodes on silicon, using technology much like that used in existing microchip production – can operate at temperatures around 1K.
This is only one degree above absolute zero, so it’s still extremely cold. However, it’s significantly warmer than previously thought possible. This breakthrough could condense the sprawling refrigeration infrastructure into a more manageable, single system. It would drastically reduce operational costs and power consumption.
Wikipedia: Striped Toothpaste
Striped toothpaste was invented by Leonard Marraffino in 1955. The patent (US patent 2,789,731, issued 1957) was subsequently sold to Unilever, who marketed the novelty under the Stripe brand-name in the early 1960s. This was followed by the introduction of the Signal brand in Europe in 1965 (UK patent 813,514). Although Stripe was initially very successful, it never again achieved the 8% market share that it cornered during its second year.
Marraffino’s design, which remains in use for single-color stripes, is simple. The main material, usually white, sits at the crimp end of the toothpaste tube and makes up most of its bulk. A thin pipe, through which that carrier material will flow, descends from the nozzle to it. The stripe-material (this was red in Stripe) fills the gap between the carrier material and the top of the tube. The two materials are not in separate compartments, but they are sufficiently viscousthat they will not mix. When pressure is applied to the toothpaste tube, the main material squeezes down the thin pipe to the nozzle. Simultaneously, the pressure applied to the main material causes pressure to be forwarded to the stripe material, which thereby issues out through small holes (in the side of the pipe) onto the main carrier material as it is passing those holes.

The iconic depiction of a wave-shaped blob of toothpaste sitting on a toothbrush is called a “nurdle”.
LATimes: Trump says he’ll jail his opponents. Members of the House Jan. 6 committee are preparing
Members of the House committee that investigated the Jan. 6 attack on the U.S. Capitol have warned America for three years to take former President Donald Trump at his word.
Now, as Trump is poised to win the Republican presidential nomination, his criminal trials face delays that could stall them past election day, and his rhetoric grows increasingly authoritarian, some of those lawmakers find themselves following their own advice.
In mid-March, Trump said on social media that the committee members should be jailed. In December he vowed to be a dictator on “day one.” In August, he said he would “have no choice” but to lock up his political opponents.
Kottke: The Sound of Knitting
The above comes across as almost a parody of itself – halfway through, I thought This could be an SNL sketch! – but it’s also delightful. It’s a trailer for The Sound of Knitting, “an evening where classical music and knitting merge.” The popular designers and podcasters Arne & Carlosteamed up with the Norwegian string instrument group (heh) Trondheimsolistene to make a concert/tutorial/behind-the-scenes knitting video, available for purchase. In addition to featuring knitting-friendly music, the video includes a tour of the Norwegian municipality of Selbu, famous for its gorgeous mittens, as well as a virtual class on how to knit those mittens. It all seems lovely, although I confess I was slightly disappointed “the sound of knitting” wasn’t an ASMR video of needles clicking, although I’m sure that’s out there, too. I mean I know it is because I’ve seen it.
