Today’s radio technology has almost nothing in common with its counterpart from a century ago. Countless advances have produced gear that is fantastically smaller, more reliable, and more efficient in its use of power and bandwidth. And yet, one enormous limitation remains from long ago: Radios still can’t transmit and receive on the same frequency at the same time.

Climate-Friendly Ethereum Is One Merge Away

Successful tests set the stage for the cryptocurrency’s switchover in September

The merge is coming, and crypto may never be the same.

“The merge” is shorthand for Ethereum’s rapidly approaching switch from one compute-intensive form of blockchain verification to a much less resource-heavy method. In other words, the cryptocurrency will be switching from proof-of-work to proof-of-stake. This move, which is years in the making, changes how Ethereum maintains consensus—and drastically slashes power consumption.

“Ethereum’s power-hungry days will soon be numbered,” says Terence Tsao, Ethereum protocol developer at Prysmatic Labs. “And I hope that’s true for the rest of the industry, too.”

This morning, Hyundai Motor Group and Boston Dynamics announced the launch of the Boston Dynamics AI Institute, to “spearhead advancements in artificial intelligence and robotics.” BDAII (I guess we’ll have to get used to that acronym!) will be located in Cambridge, Mass., with more than US $400 million of initial investment from Hyundai (Boston Dynamics’ parent company) and BD itself to get things started. Heading up the whole thing will be Boston Dynamics founder Marc Raibert himself, with Al Rizzi (Boston Dynamics’ chief scientist) as chief technology officer.

This new venture looks promising.

Accelerate Time to Market with Calibre nmLVS Recon Technology: A New Paradigm for Circuit Verification

One thing is clear…tapeouts are getting harder, and taking longer. As part of a growing suite of innovative early-stage design verification technologies, the Calibre nmLVS Recon tool enables design teams to rapidly examine dirty and immature designs to find and fix high-impact circuit errors earlier and faster, leading to an overall reduction in tapeout schedules and time to market.
