Dart 2 Native


Dart 2.6 Goes Native on Linux, Windows, and MacOS

The latest version of Google programming language Dart, numbered 2.6, extends support for native, ahead-of-time (AOT) compilation with the addition of dart2native, which enables the creation of command-line programs on Linux, Windows, and MacOS.
Importantly, dart2native generates self-contained binaries, meaning they do not require the Dart SDK to run.

Tesla's Gigafactory 4 in Germany

Tesla's Gigafactory 4 Is One Of Elon Musk's Smartest Moves - Tesla, Inc. (NASDAQ:TSLA) | Seeking Alpha



"The company plans on investing in a new electric car factory near Berlin. The factory is expected to go into operation at the end of 2021 and will initially build the future Model Y compact off-roader as well as batteries and drives. Elon Musk had also announced that an engineering and design centre would be located in Berlin."


Tesla Gigafactory 3 - Electrek

Tesla has finally obtained its manufacturing license to start production at Gigafactory 3 in Shanghai — indicating that production is imminent at the new factory.

Tesla is planning a massive service, sales, and charging infrastructure expansion in China ahead of the expected increase in vehicle sales due to volume production at Gigafactory 3.





"The Tesla Gigafactory 2 is a photovoltaic (PV) cell factory leased by Tesla subsidiary SolarCity in Buffalo, New York. The factory, owned by the State of New York, was built on brownfield land remediated from a former steel mill. Construction of the factory started in 2014 and was completed in 2016–17."

Elon Musk: Neuralink, AI, Autopilot, and the Pale Blue Dot

Elon Musk: Neuralink, AI, Autopilot, and the Pale Blue Dot | MIT | Artificial Intelligence Podcast

transcript.pdf

Elon Musk: 34:18
Earth as a small blue dot in a fuzzy beam of light."Channeling Carl Sagan. Look again at that dot that's here. That's home. That's us. On it, everyone you love, everyone you know, everyone you've ever heard of, every human being who ever was lived out their lives. The aggregate of our joy and suffering. Thousands of confident religions, ideologies and economic doctrines. Every hunter and forager, every hero and coward, every creator and destroyer of civilization, every King and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer. Every teacher of morals, every corrupt politician, every superstar, every supreme leader, every Saint and sinner in the history of our species lived there. Automotive dust suspended in a sun beam.

Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all those vastness, there is no hint that help will come from elsewhere to save us from ourselves. The earth is the only world known so far to harbor life. There was nowhere else, at least in the near future to which our species could migrate."

Tesla (TSLA) stock down after electric pickup unveiling — market is missing the point - Electrek

"...Tesla figured out some significant cost improvements in both battery costs and manufacturing a vehicle with this new exoskeleton structure...
...Right now, the cheapest vehicle that Tesla is selling with a 100 kWh battery pack is the Model S Long Range, which costs $80,000.

The Cybertruck starts at half that price."


A few too many rounds: Tesla CyberTruck window shattering
"The leading theory is that the repeated launches of the steel ball against the window led to microfractures, which compromised the glass leading to its ultimate shattering on stage."

Elon Musk on Twitter: "Franz throws steel ball at Cybertruck window right before launch. Guess we have some improvements to make before production haha. https://t.co/eB0o4tlPoz" / Twitter

WASM: Web Assembly, AssemblyScript book

Web Assembly (WASM) comes in two formats:
  • portable binary format, with file extension .wasm
  • text format, with file extension .wat
For most cases .wat is still quite low level, and there is option to use an "AssemblyScript",
an extended strongly typed subset of TypeScript, and compile that to .wasm directly.
The file extension of AssemblyScript is still .ts, same as TypeScript, and that may confuse IDEs.


Converting WebAssembly text format to wasm - WebAssembly | MDN

Introduction - The AssemblyScript Book

assemblyscript/examples at master · AssemblyScript/assemblyscript @GitHub

The simplest way to get started with WebAssembly - Benedek Gagyi - Medium


.WASM is also a compile target for many languages now.



  • Rust is quite popular choice since it produces safe, compact and efficient .wasm code, and has good tools for WebAssembly toolchain.
  • GoLang compiler provides .wasm compilation target also, while files are larger singe it includes runtime with its own GC
  • C-based languages that are using LLVM (C, C++, Swift) have compilation target for .wasm
  • .NET Core (C#) can be compiled to .wasm, by leveraging Mono compiler that is C/LLVM based. The runtime is included and relatively large, while tools are quite good. "Blazor" is leveraging ASP.NET C# templates for web apps.

Useful code examples:

hybrid cloud: Azure Arc

Why Azure Arc Is A Game Changer For Microsoft

"With Azure Arc, Microsoft has expanded the support for ARM to resources running outside of Azure. This means, a physical server running in a data center looks like a compute resource in the eyes of the Fabric Controller. Even VMs running on top of VMware vSphere, Amazon EC2, and Google Compute Engine can be registered with the Azure Resource Manager. Any Windows or Linux server - even those running behind a firewall and proxy - can be registered with ARM. The external VMs run a similar software like the agent that runs inside Azure VMs."
