NVIDIA Announces $59 Jetson Nano 2GB, A Single Board Computer With Makers In Mind

NVIDIA kicked off their line of GPU-accelerated single board computers back in 2014 with the Jetson TK1, a $200 USD development system for those looking to get involved with the burgeoning world of so-called “edge computing”. It was designed to put high performance computing in a small and energy efficient enough package that it could be integrated directly into products, rather than connecting to a data center half-way across the world.

The TK1 was an impressive piece of hardware, but not something the hacker and maker community was necessarily interested in. For one thing, it was fairly expensive. But perhaps more importantly, it was clearly geared more towards industry types than consumers. We did see the occasional project using the TK1 and the subsequent TX1 and TX2 boards, but they were few and far between.

Then came the Jetson Nano. Its 128 core Maxwell CPU still packed plenty of power and was fully compatible with NVIDIA’s CUDA architecture, but its smaller size and $99 price tag made it far more attractive for hobbyists. According to the company’s own figures, the number of active Jetson developers has more than tripped since the Nano’s introduction in March of 2019. With the platform accessible to a larger and more diverse group of users, new and innovative applications for machine learning started pouring in.

Cutting the price of the entry level Jetson hardware in half was clearly a step in the right direction, but NVIDIA wanted to bring even more developers into the fray. So why not see if lightning can strike twice? Today they’ve officially announced that the new Jetson Nano 2GB will go on sale later this month for just $59. Let’s take a close look at this new iteration of the Nano to see what’s changed (and what hasn’t) from last

The Quantum Internet Will Blow Your Mind. Here’s What It Will Look Like

This article appeared in the November 2020 issue of Discover magazine as “The Quest for a Quantum Internet.” Subscribe for more stories like these.

Call it the quantum Garden of Eden. Fifty or so miles east of New York City, on the campus of Brookhaven National Laboratory, Eden Figueroa is one of the world’s pioneering gardeners planting the seeds of a quantum internet. Capable of sending enormous amounts of data over vast distances, it would work not just faster than the current internet but faster than the speed of light — instantaneously, in fact, like the teleportation of Mr. Spock and Captain Kirk in Star Trek.

Sitting in Brookhaven’s light-filled cafeteria, his shoulder-length black hair fighting to free itself from the clutches of a ponytail, Figueroa — a Mexico native who is an associate professor at Stony Brook University — tries to explain how it will work. He grabs hold of two plastic coffee cup lids, a saltshaker, a pepper shaker and a small cup of water, and begins moving them around on the lunch table like a magician with cards.

“I’m going to have a detector here and a detector here,” he says, pointing to the two lids. “Now there are many possibilities. Either those two go in here” — he points to the saltshaker — “or the two go in there,” nodding at the cup of water. “And then depending on what happened there, that will be the state,” he says, holding up the black pepper shaker, “that I’m preparing here.” 

Got that? Me neither. But don’t worry. Only a few hundred or so physicists in the U.S., Europe and China really comprehend how to exploit some of the weirdest, most far-out aspects of quantum physics. In this strange arena, objects can exist in two or more
