If you’re looking for an existential sci-fi flick that’ll force you to question the fabric of reality, please follow my request…

Stop scrolling on whatever streaming service you’ve been staring at, pop onto Prime Videos and watch 2013’s low-budget sci-fi flick Coherence ASAP — it’s free for subscribers, right now. I know. I just watched it… for the fourth time.

The initial premise of Coherence is fairly simple. A few friends meet up for a dinner party the same night a mysterious comet is scheduled to fly overhead. It begins as many indie movies do, with a troubled love story, tension between exes and witty banter.

Then the power goes out. It gets weird. Act two.

Inexplicable events ensue while the ensemble of characters scramble to restore the power. Nothing is as it had seemed. Some start to doubt where they are, others are more concerned with who they are. This isn’t a movie about longtime pals’ small talk. It’s a tale about them coming face-to-face with the terrifying truth of their reality.

If I share any more, I’d be risking massive spoilers about the shocking revelations uncovered during the film. I can assure you, though, that the onscreen confusion is potent enough to force you to question your own sanity.

I’m only mildly exaggerating.

The next hour or so overflows with plot twists that could rival those of 2010’s Shutter Island. The film also expertly alludes to scientific — and rather philosophical — concepts that have probably

Most of us have had nights where we knew we needed to be asleep at a certain time so we could get up early. But instead, we got busy or distracted and didn’t get to sleep on time.

It can take the average American 10 to 20 minutes to fall asleep. According to the Sleep Foundation, adults between 18 and 64 need seven to nine hours of sleep. However, 35.2% of US adults report sleeping an average fewer than seven hours per night.

These are simple practices that can become daily habits once you become used to including them.

How to train yourself to go to sleep early

Below are some tips for training yourself to go to sleep earlier, which can become part of your nightly routine with practice.

Make small changes every night

It can be hard to just simply decide to go to bed a full two to three hours earlier. That might require more juggling of your schedule, or your body might not even be used to sleeping at that time.

Instead, try to go to sleep 15 to 20 minutes before your usual bedtime. That way it won’t significantly throw your normal sleep schedule off. Try sleeping at that earlier time for a few nights to a week. Then adjust going to bed 15 minutes

It’s a widely understood fact of life that not everything turns out the way you’d expect. No one knows this better, perhaps, than contestants on the popular competition show The Great British Bake Off, known in the US as The Great British Baking Show. Every week, they take a dramatic, sugar-filled journey across the uncertain and sometimes tumultuous expansion between what they planned to bake and how it turned out.

Cake sink. Buttercream icing splits. Isomalt shatters. Occasionally, someone forgets to turn on the oven, losing valuable time. But even if the sponge is “claggy” or “stodgy” (or god forbid, ends up on the floor before it makes it to a judge’s plate), there’s a perfectly executed version of the creation that viewers at home can ooh and aah at anyway.

That’s thanks to Tom Hovey, whose appetite-triggering illustrations have become a signature element of the show over the years. They’re presented on screen in a digital notebook on a mock worktop, as if the bakers had sketched them themselves.

“That points to why the illustrations are sometimes, a lot of the times, better than what it turns out in the tent, because it’s what they intended to create, not what they actually created,” Hovey said via Zoom from his studio in Newport , South Wales. GBBO’s 13th season is halfway through on Netflix. It’s already seen structurally questionable masks made of cookies; black pudding on pizza; and a coconut sponge that tasted “a bit like tanning lotion.”

Two months after the US choke off China’s access to two of Nvidia’s high-end microchips, the American semiconductor design giant unveiled a substitute with a reduced processing speed for its second-largest market.

The Nvidia A800 graphics processing unit is “another alternative product to the Nvidia A100 GPU for customers in China,” a spokesperson for Nvidia said in a statement to TechCrunch. “The A800 meets the US government’s clear test for reduced export control and cannot be programmed to exceed it.” The new chip was first reported by Reuters on Monday.

The A100 processor is known for powering supercomputers, artificial intelligence, and high-performing data centers for industries ranging from biotech and finance to manufacturing. Alibaba’s cloud computing business has been one of its customers. A100, along with Nvidia’s enterprise AI chip H100, were placed under a US export control list to “address the risk that the covered products may be used in, or diverted to, a ‘military end use’ or ‘military end user’ in China and Russia.”

Nvidia previously reported that the US ban could affect as much as $400 million in potential sales to China in the third quarter, so the new chip seems to be an attempt to remedy the financial loss. The A800 GPU went into production in Q3, according to Nvidia’s spokesperson.

Indeed, chip distributors in China, such as Omnisky, are already marketing A800 in their product catalogs. The chip looks to be designed to circumvent US export rules while still carrying out other core computing
