Amazon orders 100,000 electric trucks

Amazon orders 100,000 electric trucks to fight climate change | Ars Technica



Amazon has ordered 100,000 electric trucks from startup Rivian, the e-commerce giant announced Thursday. The order is part of Amazon's larger pledge—also announced today—to reach zero net carbon emissions by 2040. Amazon aims to use 80% renewable energy by 2024 and 100% by 2030.

Rivian is an electric-vehicle startup that is initially focusing on trucks and SUVs. Amazon led a $700 million funding round for the company earlier this year.

"The first electric delivery vans will go on the road in 2021," said Amazon CEO Jeff Bezos at an event in Washington DC. "The 100,000 will be completely deployed by 2024, let's say."

Static TypeScript (STS)

Microsoft Presents Static TypeScript, a Fast Subset of TypeScript Targeting Embedded Devices

Static TypeScript is a syntactic subset of TypeScript, built specifically to target microcontroller units (MCUs), and which compiles to machine code that runs efficiently on MCUs in the target RAM range of 16-256kB.

STS eliminates the most dynamic features of JavaScript, like with, eval, prototype-based inheritance, the arguments keyword, or the .apply method. The this pointer and the new syntax are not allowed outside classes or on non-class types. STS also does not implement recent additions to the JavaScript language, such as generators, the await and async function expressions, or file-based modules.

Python 4 IoT

Hanselminutes Technology Podcast - Fresh Air and Fresh Perspectives for Developers - Learning CircuitPython with Scott Shawcroft

"CircuitPython is a programming language designed to simplify experimenting and learning to code on low-cost microcontroller boards. The history of CircuitPython begins with MicroPython, a Python interpreter written from scratch for embedded systems by Damien George starting in 2013. Three years later, Adafruit hired Shawcroft to port MicroPython to the SAMD21 chip they use on many of their boards. The Scott talks about how to lower the barrier to entry and how to enable beginners to be productive with CircuitPython."

The World's Most Important Electric Car Is Launching Now, And It's Not A Porsche Or Tesla - The Drive

"The Renault City K-ZE has just been announced for the Chinese market, where it offers a stunning combination of electric range and low cost. Starting at 61,800 Yuan, or about $8,700 US Dollars, and its 30kWh Tianjin Lishen battery offers a remarkable 250 km, or 155 miles of NEDC-rated range. Even though this ends up resulting in a likely EPA range closer to about 100 miles, the fact that this eminently usable amount of range is available in a useful and well-proven vehicle for under $10,000 is a remarkable achievement."

EV: Rivian += $350 from Cox Automotive

Electric truck maker Rivian lands $350 million investment from Cox Automotive

"Plymouth-based electric vehicle startup Rivian Automotive LLC has netted a $350 million investment from Atlanta-based Cox Automotive as the automaker readies to produce its first vehicles.
The investment announced Tuesday follows $500 million from Ford Motor Co., and $700 million from Amazon.com Inc. earlier this year. Rivian aims to launch its first electric pickup truck and electric SUV by 2021. The automaker is currently renovating an old Mitsubishi plant in central Illinois where it plans to start building those vehicles late next year."

Low Earth orbit (LEO) satellite internet could save $30B

Bezos and Musk’s satellite internet could save Americans $30B a year

"LEO technology will offer robust internet access to underserved and rural communities lacking wired, low-latency broadband options. The arrival of this technology is likely to drive down monthly internet prices for hundreds-of-millions of Americans.

According to further analysis of our market-wide pricing database covering plans and pricing from more than 2,000 ISPs, the average “lowest available monthly price” for the estimated 104 million Americans with only one wired broadband provider is $68. For the 75 million Americans with two choices, that average lowest price drops to $59. For the lucky 15 million Americans with five or more choices, it’s $47.

Our projections show that that low-latency, LEO satellite internet is likely to have a similar impact on average regional prices as wired, low-latency wired providers. Extrapolating this additional competitor across all US households, the introduction of LEO satellite internet could save Americans over $30 billion."

D3.js v5.0

d3/CHANGES.md at master · d3/d3

D3 v5.0 uses Promises instead of asynchronous callbacks to load data. Promises simplify the structure of asynchronous code, especially in modern browsers that support async and await.

D3 v4.0 is modular. Instead of one library, D3 is now many small libraries that are designed to work together. You can pick and choose which parts to use as you see fit. Each library is maintained in its own repository, allowing decentralized ownership and independent release cycles. The default bundle combines about thirty of these microlibraries.
