web tools: preact, lit-html, svelte, stencil vs react, angular

while web components are being standardized and implemented in all modern browsers
web development is still done with many JavaScript/TypeScript tools

those tool chains are getting quite complex, and resulting web apps quite large.
and while there are many and changing options for js/web tools, React is still dominant

AWS Glue Elastic Views

AWS Glue Features – AWS Glue Elastic Views – Amazon Web Services

AWS Glue Elastic Views makes it easy to build materialized views that combine and replicate data across multiple data stores without you having to write custom code.

New applications and features often require you to combine data that resides across multiple data stores, including relational and non-relational databases. Accessing, combining, replicating, and keeping this data up-to-date requires manual work and custom code that can take months of development time.

With AWS Glue Elastic Views, you can use familiar Structured Query Language (SQL) to quickly create a virtual table—a materialized view—from multiple different source data stores. AWS Glue Elastic Views copies data from each source data store and creates a replica in a target data store. AWS Glue Elastic Views continuously monitors for changes to data in your source data stores and provides updates to the materialized views in your target data stores automatically, ensuring data accessed through the materialized view is always up-to-date.

AWS Babelfish for PostgreSQL: Translating T-SQL from SQL Server: open source

  Want more PostgreSQL? You just might like Babelfish | AWS Open Source Blog

Babelfish for PostgreSQL is an Apache-2.0 open source project that adds a Microsoft SQL Server-compatible end-point to PostgreSQL to enable your PostgreSQL database to understand the SQL Server wire protocol and commonly used SQL Server commands. With Babelfish, applications that were originally built for SQL Server can work directly with PostgreSQL, with little to no code changes, and without changing database drivers.

Babelfish for PostgreSQL will be available on Github in 2021.

Open source tools to easily build and maintain your event-driven architecture. All powered by the AsyncAPI specification, the industry standard for defining asynchronous APIs.


AWS Lambda + Containers!

 AWS Lambda now supports container images as a packaging format


You can now package and deploy AWS Lambda functions as a container image of up to 10 GB. This makes it easy to build Lambda based applications using familiar container tooling, workflows, and dependencies. Just like functions packaged as ZIP archives, functions deployed as container images will benefit from AWS Lambda’s operational simplicity, automatic scaling with sub-second startup times, high availability, and native integrations with 140 AWS services. Customers can start building functions as container images by using either a set of AWS base images for Lambda, or by using one of their preferred community or enterprise images.

Running Python on .NET 5

 Running Python on .NET 5

Pyjion is a project to replace the core execution loop of CPython by transpiling CPython bytecode to ECMA CIL and then using the .NET 5 CLR to compile that into machine code. It then executes the machine-code compiled JIT frames at runtime instead of using the native execution loop of CPython.

Mac Mini @ AWS EC2

StatusCode Weekly Issue 295: December 2, 2020

"AWS Unveils Mac-Powered EC2 Instances — Exciting news because the big clouds have kept away from macOS so far, but.. for good reason. These are ultimately very expensive ($1.21/hr on demand) and restricted (the minimum time you can use one is 24 hours – more on why here). If you’re heavily into AWS, though, and want to wrap macOS-based CI/CD into your monthly bill, now there’s a way."


it would pay off in less than a month to purchase instead of this "lease"...

AWS Babelfish for Aurora PostgreSQL

 AWS goes after Microsoft’s SQL Server with Babelfish for Aurora PostgreSQL | TechCrunch

AWS today announced a new database product that is clearly meant to go after Microsoft’s SQL Server and make it easier — and cheaper — for SQL Server users to migrate to the AWS cloud. The new service is Babelfish for Aurora PostgreSQL. The tagline AWS CEO Andy Jassy used for this service in his re:Invent keynote today is probably telling: “Stop paying for SQL Server licenses you don’t need.” And to show how serious it is about this, the company is even open-sourcing the tool.

What Babelfish does is provide a translation layer for SQL Server’s proprietary SQL dialect (T-SQL) and communications protocol so that businesses can switch to AWS’ Aurora relational database at will (though they’ll still have to migrate their existing data). It provides translations for the dialect, but also SQL commands, cursors, catalog views, data types, triggers, stored procedures and functions.

The promise here is that companies won’t have to replace their database drivers or rewrite and verify their database requests to make this transition.

web "variable fonts"

Introduction to variable fonts on the web

A typeface is the underlying visual design that can exist in many different typesetting technologies, and a font is one of these implementations, in a digital file format. In other words, a typeface is what you see, and the font is what you use.

A style is a single and specific typeface, such as Bold Italic, and a family is the complete set of styles.

Before variable fonts, each style was implemented as a separate font file.
With variable fonts, all styles can be contained in a single file.

AWS ALB: HTTP/2 and gRPC

 New – Application Load Balancer Support for End-to-End HTTP/2 and gRPC | AWS News Blog

gRPC is a popular choice for microservice integrations and client-server communications. gRPC is a high performance remote procedure call (RPC) framework using HTTP/2 for transport and Protocol Buffers to describe the interface.

To make it easier to use gRPC with your applications, Application Load Balancer (ALB) now supports HTTP/2 end-to-end, enabling you to publish gRPC services alongside non-gRPC services via a single load balancer. You can use Amazon Elastic Compute Cloud (EC2) instances or IP addresses (for example with AWS Fargate) as gRPC targets, with support for gRPC health checks for the target groups. In this way, you can use ALBs to terminate, route and load balance the gRPC traffic between your microservices or between gRPC-enabled clients and services.

SpaceX Starlink internet service

 Starlink testers will pay $99 per month for SpaceX's satellite internet | Engadget

SpaceX’s Starlink internet satellite will cost early beta testers $99 a month, not including the $499 upfront cost for the hardware kit needed to access the network.

Speeds will vary from 50Mb/s to 150Mb/s and latency from 20ms to 40ms over the next several months, it warns, and there will even be brief periods with no connectivity at all. The apps will help users identify the best install location for the Starlink receiver dish and will help check for obstructions that can interfere with service. They will also have instructions on how to install Starlink hardware, can do speed tests and can connect subscribers with customer service.

Solargon: passive solar octagon house

TECH INFO - ICS Eco-SIPs - A BETTER WAY TO BUILD

INSULATED COMPONENT STRUCTURES
ECO-FRIENDLY STRUCTURAL INSULATED PANELS (ICS Eco-SIPs)
is a Manufacturer of Building Components offering Modern Alternatives to Conventional Building Methods

 Solargon - The Passive Solar Smart Cabin (Official Website) - Solargon Passive Solar Designs from ICS Eco-SIPs

"Even during a mostly cloudy day, the Solargon will gain solar energy and efficiently heat itself without an internal heat source."

​Solargon's Passive solar designs can reduce demand for heat by 60%.

Model 30 (699 square feet octagon)

octagonal shape uses 20% less materials to enclose the same square footage as a standard rectangular home or building. 

Solargons go together very quickly. Erection and seal-in of the structure requires only a few hours for a 20' Solagon and two days for a 30' Solargon. Structural finishes such as flooring, cabinets, fixtures, detailing, and any internal wall construction will take a varying amount of time depending on your choices. It’s reasonable to anticipate being in your completed Solargon within a very few weeks, using an experienced contractor.


Solargon 30' Specs
Floor area 695 sq. ft.
Wall size: 12’w x 8’H or (optional 10’ high walls for loft area)
Total wall area for 8' high wall 768 sq. ft.
Total wall area for 10' high wall 960 sq. ft.
Concrete foundation size: 12’ sides x 12’= 96 l/f of footings w/ stem wall to frost line.
This model is only available in the 4-sided roof.
Roof area 267 sq. ft. per section
Total roof area 1,068 sq. ft.


MSRP for the 30′ model is $ 39,900
Included:
All walls R42 and roof panels R42, micro-lam headers, wall to wall connectors, glue-lam super structure and rafters, operable skylight,compression frame w/header and assembly manual. Wall and roof panels cam-lock together and the typical erection time is 2 days.

When your home is up you have the walls, roof, insulation, and rough electrical with boxes ready to go for about $55.00 per sq. ft. You then choose the interior and exterior finishing of your choice. An average home will cost about $125 to $150 per sq. ft. to finish so Solargons are very competitive.
