TESLA REMOVES STOCK-BASED COMPENSATION THIS YEAR

Tesla has reportedly decided not to give stock-based compensation to employees as part of their annual performance reviews this year. Some employees who were reaching the end of their four-year vesting cycles were given stock refreshers to keep their total compensation competitive. Tesla is still doing modest cost-of-living increases and adjustments to its base salaries. It is unclear whether this will be a new policy going forward. Tesla regularly changes its employee compensations, and not always in a straightforward way.

FETCH WATERFALL IN REACT

A “fetch waterfall” is a common data fetching issue in React. It happens when you create a hierarchy of components that fetch their own data and show “loading” states before child components are rendered. There are a couple of ways to resolve this: by fetching data from the server (it’s not always as simple as using a server component), hoisting the data fetching to a higher level component, or through Suspense, which triggers the whole component tree’s fetches in parallel.

CELESTIA RIVAL AVAIL PARTNERS WITH STARKWARE FOR BLOCKCHAIN DATA

Blockchain data firm Avail, a rival of Celestia, announced a partnership with Starknet to enhance data access for the L2 network. By leveraging Starknet sequencer Madara, Avail seeks to offer data solutions for developers' app chains, potentially cutting costs and enabling more innovation in the ecosystem. The integration is expected to lower data publishing prices by 90% and help achieve quicker transaction finality. Although Avail's testnet will only go live in Q3 2024, developers have immediate access for experimentation.

APPLE PLANNING TO LAUNCH VISION PRO BY FEBRUARY

Apple has ramped up production of the Vision Pro to meet its goal of launching the device by February. Sales of the device will be limited to the US to begin with. Customers will need to purchase or pick up their devices in-store as Apple wants to ensure customers have the right headband size and Light Seal for an appropriate fit. Apple plans to do headset assembly for customers who need custom Zeiss prescription lenses in its retail locations. There probably won't be a launch event for the device.

THE BRAIN-IMPLANT COMPANY GOING FOR NEURALINK’S JUGULAR

Synchron has a brain-computer interface that promises to provide an invaluable communication method to people with severe paralysis without open brain surgery. The device is delivered like a stent, inserted into the jugular vein in the neck and then moved to a blood vessel near the brain's motor cortex. It allows people who suffer from brain-stem stroke or degenerative diseases to do basic computer tasks like sending messages and accessing digital health services without moving a muscle. The company is now in the middle of a US-based feasibility study, which, if successful, could lead to a larger study that will determine whether the device gets approved for clinical use.

WAYMO FINDS THAT ITS DRIVERLESS CARS ‘SIGNIFICANTLY OUTPERFORMED’ HUMANS

A safety study from Waymo found that its driverless cars led to a significant reduction in the rates of police-reported and injury-causing crashes compared to human drivers. There were 85% less injuries for crashes involving the Waymo Driver and 57% fewer police reports. The accidents covered in the study included all crashes, regardless of the vehicle's role in the crash. Waymo is pushing broadly for international standardization for valid analysis of autonomous vehicle crash data.
