Fresh: new web framework from Deno team

Deno's Fresh new web framework featuring Luca Casonato (JS Party #234) |> Changelog

Deno’s Discord

Fresh is a full stack modern web framework for JavaScript and TypeScript developers, designed to make it trivial to create high-quality, performant, and personalized web applications. You can use it to create your home page, a blog, a large web application like GitHub or Twitter, or anything else you can think of.

At its core, Fresh is a combination of a routing framework and templating engine that renders pages on demand, on the server. In addition to this just-in-time (JIT) rendering on the server, Fresh also provides an interface for seamlessly rendering some components on the client for maximum interactivity. The framework uses Preact and JSX for rendering and templating on both the server and the client.

Fresh also does not have a build step. The code you write is also directly the code that is run on the server, and the code that is executed on the client. Any necessary transpilation of TypeScript or JSX to plain JavaScript is done on the fly, just when it is needed. This allows for insanely fast iteration loops and very very fast deployments.

Azure "Giga" server

 Use One Big Server - Speculative Branches

Microsoft Azure with AMD CPUs.

  • 64 cores
  • 128 threads
  • ~2-2.5 GHz clock
  • Cores capable of 4-6 instructions per clock cycle
  • 256 MB of L3 cache
16 slots of DDR4-3200 RAM per socket. The largest capacity “cost effective” DIMMs today are 64 GB. Populated cost-efficiently, this server can hold 1 TB of memory. Populated with specialized high-capacity DIMMs (which are generally slower than the smaller DIMMs), this server supports up to 8 TB of memory total.

In AWS, one of the largest servers you can rent is the m6a.metal server. It offers 50 Gbps of network bandwidth, 192 vCPUs (96 physical cores), and 768 GB of memory, and costs $8.2944/hour in the US East region. 

A similar server, with 128 physical cores and 512 GB of memory (as well as appropriate NICs, SSDs, and support contracts), can be purchased from the Dell website for about $40,000.

C# Web Assembly without Blazor

C# can be compiled to WASM. 
That is automated for "Blazor" type of .NET projects
but it can be done even independently!

The end result is also very small, without dependencies.

WASM may (will!) very well become "new Docker",
a lightweight secure platform to run any code anywhere!

 Using C# Web Assembly without using Blazor*

"All in all this loads just over 70KB of resources over the wire and uncompressed that is just over 300KB."

Ethereum: “proof-of-work” (PoW) => “proof-of-stake” (PoS)

 The Merge, merged - by a16z crypto - web3 weekly

"Transitioning Ethereum to “proof-of-stake” (PoS) from “proof-of-work” (PoW) – two very different methods for reaching consensus on blocks of transactions – was an insane feat: The update involved hot-swapping the most important component of Ethereum’s architecture, its consensus mechanism, *while it was running*. [One core dev described this as “changing the engine on a moving car”.] All this occurred while maintaining perfect uptime for millions of users, thousands of decentralized applications (dapps), and hundreds of billions of dollars secured."

Node.js Streams

Node.js Streams

Streams are one of the fundamental concepts that power Node.js applications.

They are a way to handle reading/writing files, network communications, or any kind of end-to-end information exchange in an efficient way.

Streams are not a concept unique to Node.js. They were introduced in the Unix operating system decades ago, and programs can interact with each other passing streams through the pipe operator (|).

Web Components Introduction: Stencil, Lit, lwc

An Introduction to Web Components @academind

Learn how to get started with web components to build re-usable components (for all frameworks!) with vanilla JavaScript.

by Maximilian Schwarzmüller of academind

Web Components consists of three main technologies, which can be used together to create versatile custom elements with encapsulated functionality that can be reused wherever you like without fear of code collisions.
  • Custom elements: A set of JavaScript APIs that allow you to define custom elements and their behavior, which can then be used as desired in your user interface.

  • Shadow DOM: A set of JavaScript APIs for attaching an encapsulated "shadow" DOM tree to an element — which is rendered separately from the main document DOM — and controlling associated functionality. In this way, you can keep an element's features private, so they can be scripted and styled without the fear of collision with other parts of the document.

  • HTML templates: The <template> and <slot> elements enable you to write markup templates that are not displayed in the rendered page. These can then be reused multiple times as the basis of a custom element's structure.

Lit is a simple library for building fast, lightweight web components.

Stencil employs JSX, while lit-element has to use lit-html as it's templating language to render to the shadow DOM. The syntax is slightly different, but similar enough that it's not a huge barrier.

if you want something as close to the standard as possible, with no extra baggage — go for lit-element. If you don't want to setup testing, go through as much boilerplate, or develop a build process — use Stencil.

Carbon: new programming language from Google, C++ replacement

Google recently announced their C++ replacement language "Carbon".

Carbon, or Carbon-Lang, is an experimental, general-purpose programming language created to be a "C++ successor". The project is open-source and was started by Google, following in the footsteps of previous Google-made programming languages (Go and Dart).

package Sample api;    

fn Main() -> i32 {
    Print("Hello, World!");
    return 0;

Carbon Programming Language  - Tutorial | Better Programming

"Rust is thoroughly evaluated as a replacement to C++. Infact Carbon language insists to use Rust and ignore Carbon if possible as Rust is technically and economically more viable language.

However for organizations that are already using C++ , it’s very difficult to migrate to Rust. Software written in Rust has properties and modules that non of the languages like C++ or Carbon has. Adapting to Rust for large C++ codebases is almost not practical given that there is no inter-operability."

Thoughts on Google Carbon - YouTube

Carbon is a new early-stage programming language from Google designed as a successor to C++ for low level systems development. It has full interoperability with Cpp, along with improved memory safety, generics, and a cleaner syntax.

Ionic Web Components + Stencil tool

Ionic framework for mobile web + native apps
since version 4 is not for mobile only, and not with Angular only!

It is based on standard web components, supported by all modern web browsers,
and those components can be used from "vanilla" JavaScript
as well as from React, Vue and Angular!

There is a large collections of ready open source web components
that dynamically adjust for both iOS and Android design style of UI.

Even better, the same apps can be used as standard web app, including with PWA!

Finally the Ionic company provides dev and build tools for the app.

When maximum mobile performance is not imperative, such as for some action games
there is no good reason not to use standard web components and Ionic!

MS Office 365 + Scheme (LISP) ?

The Excellent Schemer @CodeMag

AccelerateTM for Microsoft 365 is a new, commercially available Microsoft Office add-in that deeply integrates the Visual Scheme for ApplicationsTM (VSATM) programming language into the popular back-office automation suite, for versions 2016 and later. VSA intends to serve as the “third musketeer,” alongside Visual Basic for Applications (VBA) and the popular formula expression language of Excel, but with a twist: Under the hood of this uniquely powerful language is the full reach and power of the .NET Framework.

At first glance, Scheme might seem an odd choice of a language to tag team with VBA and Excel's formula expression language. On closer inspection, and especially considering Microsoft's new, explicitly “functional programming” direction with Excel's formula expression language, Scheme seems the inevitable choice.

One thing that surprises developers who haven't yet had a chance to explore a proper Lisp is how similar the new LET/LAMBDA functions in Excel look, or at least feel, like Lisp/Scheme. Here is an example of an Excel LAMBDA/LET function:


Now here's the same thing in Scheme:

(lambda (x y) (let ((xs (* x x)) (ys (* y y))) (sqrt (+ xs ys))))
