Tesla aims to eventually have the robot in people's homes performing a wide range of tasks, but it first plans to have them in its own manufacturing operations for repetitive and or dangerous tasks. The video of the robot folding a shirt is available in the article.

The slowdowns may be due to ad blockers altering YouTube's code and unrelated to YouTube.

NEW SOLID STATE BATTERY CHARGES IN MINUTES, LASTS FOR THOUSANDS OF CYCLES

Researchers at Harvard John A. Paulson SEAS have developed a new lithium metal battery that can be charged in minutes and lasts at least 6,000 charging cycles. Lithium metal batteries offer far better energy density and much lower weight than their lithium-ion counterparts. The team has a list of other materials that could potentially yield similar performance. The technology has been licensed through a Harvard spinoff company that has scaled it up to build a smartphone-sized pouch cell battery.

SLASHING DATA TRANSFER COSTS IN AWS BY 99%

One of the easiest ways to accidentally spend too much money on AWS is by carelessly transferring data.

These prices easily add up and are an extremely high-margin source of profit for cloud providers. This article looks at how to set up cross-availability zone infrastructure without paying for data transfer costs. It suggests using S3, which already replicates data between availability zones as part of its service.

ELON MUSK WANTS MORE CONTROL OF TESLA, SEEKS 25% VOTING POWER

Elon Musk said on Monday that he wants about 25% of voting control over Tesla. Musk already owns around 13% of the company. He says that he is uncomfortable growing Tesla to be a leader in AI and robotics without having the control. He wants to be influential, but not so much that he can't be overturned. The bid for more control will add to the pressure on Tesla's board of directors, who is already facing investor concerns over several issues, including Musk's split focus, the use of company resources, and federal probes.
