Square's New Name 'Block' Highlights Company Focus on Blockchain

Andrew Orr ·

When pondering what Jack Dorsey would do after his departure from Twitter, my first thought was focusing on Square and cryptocurrency. Now, a few days later, the company has changed its name to Block.

We built the Square brand for our Seller business, which is where it belongs. Block is a new name, but our purpose of economic empowerment remains the same. No matter how we grow or change, we will continue to build tools to help increase access to the economy.

Nvidia Builds 'Earth-2' Supercomputer to Accurately Simulate Climate Change

Andrew Orr ·

Nvidia is building a powerful supercomputer it calls Earth-2. They want to use simulation to make predictions in climate change with meter-scale resolution.

For the first time, we have the technology to do ultra-high-resolution climate modeling, to jump to lightspeed and predict changes in regional extreme weather decades out.

We can achieve million-x speedups by combining three technologies: GPU-accelerated computing; deep learning and breakthroughs in physics-informed neural networks; and AI supercomputers, along with vast quantities of observed and model data to learn from.
