UPS += electric_vans * 10000 + self_driving
UPS orders 10,000 electric delivery vans from startup Arrival
"UPS announced today that they are investing in UK-based EV startup Arrival and ordering 10,000 electric delivery vans from them in order to electrify their fleet."
UPS is buying thousands of electric vans and teaming up with Waymo to accelerate the future of delivery

"... UPS will use some of (Alphabet/Google subsidiary) Waymo’s self-driving Chrysler Pacifica minivans to shuttle packages between some of its stores in the Metro Phoenix area and its hub in Tempe, Arizona. The minivans won’t be fully driverless; Waymo says it will keep trained safety drivers in the front seat to monitor operations. Despite the limited nature of the pilot, both Waymo and UPS say a “long-term plan” between the companies remains possible."
Hyundai and Kia put over $110M into UK electric delivery vehicles startup Arrival
"Last year Hyundai announced a $35 billion commitment to develop self-driving technology and electric vehicles. As part of that, it wants to release 23 types of electric vehicles by 2025.
Last week, it unveiled a flying taxi concept with Uber at the CES tech conference in Las Vegas."

AWS SAM: Serverless Application Model
AWS Serverless Application Model - Amazon Web Services
The AWS Serverless Application Model (SAM) is an open-source framework for building serverless applications. It provides shorthand syntax to express functions, APIs, databases, and event source mappings. With just a few lines per resource, you can define the application you want and model it using YAML. During deployment, SAM transforms and expands the SAM syntax into AWS CloudFormation syntax, enabling you to build serverless applications faster.
To get started with building SAM-based applications, use the AWS SAM CLI. SAM CLI provides a Lambda-like execution environment that lets you locally build, test, and debug applications defined by SAM templates. You can also use the SAM CLI to deploy your applications to AWS.

energy efficiency: Manitoba Hydro Building
wikipedia.org/wiki/Manitoba_Hydro_Place
Manitoba Hydro Place received LEED Platinum certification in May 2012, making it the most energy efficient office tower in North America
The building's bioclimatic, energy-efficient design features a 377 ft (115 m) tall solar chimney, a geo-thermal HVAC system using 280 five-inch tubes bored 380 feet into an underground aquifer,[10] 100% fresh air (24 hours a day, year round, regardless of outside temperature)[8] and a one-meter-wide double exterior wall with computer-controlled motorized vents that adjust the building's exterior skin throughout the day and evening. Together, the various elements of the design enable a 70% energy savings over a typical large office tower.

Amazon Ion: JSON++ for QLDB
Amazon Ion
"Amazon Ion is a richly-typed, self-describing, hierarchical data serialization format offering interchangeable binary and text representations. The text format (a superset of JSON) is easy to read and author, supporting rapid prototyping. The binary representation is efficient to store, transmit, and skip-scan parse. The rich type system provides unambiguous semantics for long-term preservation of data which can survive multiple generations of software evolution.
Ion was built to address rapid development, decoupling, and efficiency challenges faced every day while engineering large-scale, service-oriented architectures. It has been addressing these challenges within Amazon for nearly a decade, and we believe others will benefit as well.
Available Libraries: Ion Java – Ion C – Ion Python – Ion JavaScript

AWS Glue is a fully managed extract, transform, and load (ETL) service that makes it easy for customers to prepare and load their data for analytics. You can create and run an ETL job with a few clicks in the AWS Management Console. You simply point AWS Glue to your data stored on AWS, and AWS Glue discovers your data and stores the associated metadata (e.g. table definition and schema) in the AWS Glue Data Catalog. Once cataloged, your data is immediately searchable, queryable, and available for ETL.

dapr: runtime for building microservices: cloud native, mesh, sidecar
dapr.ioAn event-driven, portable runtime for building microservices on cloud and edge.
github.com/dapr (GoLang, MIT license)
"Dapr injects a side-car container/process to each compute unit.
The side-car interacts with event triggers and communicates with the compute unit via standard HTTP or gRPC protocols. This enables Dapr to support all existing and future programming languages without requiring you to import frameworks or libraries.
Dapr offers built-in state management, reliable messaging (at least once delivery), triggers and bindings through standard HTTP verbs or gRPC interfaces. This allows you to write stateless, stateful and actor-like services following the same programming paradigm. You can freely choose consistency model, threading model and message delivery patterns.
Dapr runs natively on Kubernetes, as a standalone binary on your machine, on an IoT device, or as a container that can be injected into any system, in the cloud or on-premises.
Dapr uses pluggable state stores and message buses such as Redis as well as gRPC to offer a wide range of communication methods, including direct dapr-to-dapr using gRPC and async Pub-Sub with guaranteed delivery and at-least-once semantics."
github.com/dapr/dapr/wiki/FAQ
"Dapr is a distributed application runtime. Unlike a service mesh which is focused on networking concerns, Dapr is focused on providing building blocks that make it easier for developers to build microservices. Dapr is developer-centric versus service meshes being infrastructure-centric."

A sidecar is a one-wheeled device attached to the side of a motorcycle, scooter, or bicycle,[1] making the whole a three-wheeled vehicle. A motorcycle with a sidecar is sometimes called a combination, an outfit, a rig or a hackSidecar on Vespa scooter
Service Mesh
wikipedia.org/wiki/Service_mesh
"In software architecture, a service mesh is a dedicated infrastructure layer for facilitating service-to-service communications between microservices, often using a sidecar proxy.
Having such a dedicated communication layer can provide a number of benefits, such as providing observability into communications, providing secure connections, or automating retries and backoff for failed requests."

C++ smart pointers vs Rust
Smart pointers (Modern C++) | Microsoft Docs
"As shown in the example, a smart pointer is a class template that you declare on the stack, and initialize by using a raw pointer that points to a heap-allocated object. After the smart pointer is initialized, it owns the raw pointer. This means that the smart pointer is responsible for deleting the memory that the raw pointer specifies. The smart pointer destructor contains the call to delete, and because the smart pointer is declared on the stack, its destructor is invoked when the smart pointer goes out of scope, even if an exception is thrown somewhere further up the stack."
void UseRawPointer() { // Using a raw pointer -- not recommended. Song* pSong = new Song(L"Nothing on You", L"Bruno Mars"); // Use pSong... // Don't forget to delete! delete pSong; } void UseSmartPointer() { // Declare a smart pointer on stack and pass it the raw pointer. unique_ptr song2( new Song(L"Nothing on You", L"Bruno Mars"));
// Use song2...
wstring s = song2->duration_;
//...
} // song2 is deleted automatically here.

Apache NiFi: NiagaraFiles, flow based programming
Apache NiFi - Wikipedia
Apache NiFi is a software project from the Apache Software Foundation designed to automate the flow of data between software systems. It is based on the "NiagaraFiles" software previously developed by the NSA, which is also the source of a part of its present name – NiFi.
Flow-based programming - Wikipedia
flow-based programming (FBP) is a programming paradigm that defines applications as networks of "black box" processes, which exchange data across predefined connections by message passing, where the connections are specified externally to the processes. These black box processes can be reconnected endlessly to form different applications without having to be changed internally. FBP is thus naturally component-oriented.
FBP is a particular form of dataflow programming based on bounded buffers, information packets with defined lifetimes, named ports, and separate definition of connections.

AWS-shell vs AWS CLI + JMESPath
https://github.com/awslabs/aws-shell
AWS Command Line Interface and aws-shell Sample for AWS Cloud9 - AWS Cloud9
"The AWS CLI and the aws-shell are unified tools that provide a consistent interface for interacting with all parts of AWS. You can use the AWS CLI or the aws-shell instead of the AWS Management Console to quickly run commands to interact with AWS, and some of these commands can only be run with the AWS CLI or the aws-shell."
