A Satisfying New TypeScript Release...

A major earthquake has hit TC39, the JavaScript standards committee. A proposal for adding type annotations to JavaScript has just landed on the committee and has been approved for Stage 1. What is this proposal all about? How did it come to be? What is the motivation behind it? What are its pros and cons? Why are some people excited about it, some wary, some angry, and some afraid? 
As one of the writers of this proposal, I will delve into the details of the proposal, and try to answer all the questions above.

Web Developer Reacts To Best Codepens!

Architectural considerations are often overlooked by developers or completely delegated to a framework. We should start once again discussing how applications are structured, how components are connected and how to lower coupling between different parts of a system, to avoid creating software that cannot easily be maintained or changed. The ""clean architecture"" model predates Robert Martin, who recently brought it back to the attention of the community, and is a way of structuring applications that leverages layers separation and internal APIs to achieve a very tidy, fully-tested, and loosely coupled system.

The talk introduces the main ideas of the architecture, showing how the layers can be implemented in Python, following the content of the book ""Clean Architectures in Python"" edited by Leanpub. The book recently reached 25,000 downloads and many readers found it useful to start learning how to test software and how to structure an application without relying entirely on the framework.

Clean Architectures in Python

Developers don’t want to do operations anymore, and that’s a bad sign for DevOps. Top-performing organizations have found that the answer to this issue lies in platform engineering, which is growing in popularity. 

Platform engineering is the discipline of designing and building toolchains and workflows that enable self-service capabilities for software engineering organizations in the cloud native era. Platform engineers provide an integrated product most often referred to as an “internal developer platform” covering the operational necessities of the entire life cycle of an application.

DevOps is dead. Embrace platform engineering.

In 2019, the WASI standardization effort was started in the WebAssembly CG as a way to bootstrap an ecosystem of safe, portable WebAssembly modules running outside (or inside) the browser. The starting point of the design, captured in WASI "Preview1", included tried-and-true POSIX concepts like files and directories. However, as the standards group worked to realize high-level goals including language neutrality, low-latency startup, low-overhead virtualization, heterogeneous host environments, fine-grained sandboxing and robust composition of programs from modules, the approach of mapping classic POSIX concepts into WebAssembly kept running into problems and a new approach had to be explored. Two years (and one pandemic) later, based on experience gained from Preview1, an improved design has emerged that splits the problem in two, factoring out a foundational "component model" layer that is implemented by the WebAssembly engine, providing a more lightweight, composable, declarative unit of code, along with new Wit and World syntax for defining WASI and other component interfaces. This talk will describe some of the original problems and how they are proposed to be addressed, present some examples of next-iteration WASI interfaces in action and discuss paths of incremental adoption.
