Protractor Testing: A Brief History and Its Relevance Today

Protractor was a test framework primarily for end-to-end testing in Angular and AngularJS applications but can also be used for non-Angular websites.
As of August 2023, Protractor has reached its end-of-life, and its use is discouraged due to the evolution of JavaScript and modern testing frameworks.
Protractor was created in 2013 by the Angular team to enhance Angular's E2E testing capabilities and address limitations in existing testing tools.
It functioned as an open-source framework for performing E2E testing on Angular apps, integrating NodeJS, Jasmine, Selenium, and more.
Protractor used an actual browser to simulate user behavior, enabling end-to-end testing starting at the UI level and covering all layers of an application.
Protractor's architecture included components like WebDriverJS, Jasmine (or Mocha/Cucumber), Selenium Server, and supported browsers like Chrome and Firefox.
End-to-end testing ensures an application's workflow functions seamlessly, simulating real user interactions across frontend, backend, and database layers.
With the dominance of frameworks like Angular and React, E2E testing plays a vital role in validating the entire user experience in modern web applications.
In April 2021, the Protractor team announced the plans to end its development due to advancements in JavaScript and testing frameworks, leading to its deprecation.
Existing Protractor users are encouraged to migrate to more modern testing solutions like Testim Automate for efficient and maintainable test suites.

Making .fullScreenCover Transparent in SwiftUI Using UIViewRepresentable

SwiftUI's .fullScreenCover by default uses an opaque background managed by UIKit's modal container.
To make .fullScreenCover transparent, SwiftUI lacks a native option, so a UIViewRepresentable is used to set the background color to .clear.
Common SwiftUI methods like .background(Color.clear) or ZStack only affect modal content, not the background container itself.
Although relying on SwiftUI's internal view hierarchy, this workaround is an effective way for achieving a transparent .fullScreenCover in SwiftUI 6.

How to Calculate FID Score for Single-Channel MNIST Images?

The Fréchet Inception Distance (FID) score is crucial for evaluating the quality of generated images in GANs but typically requires RGB images, posing a challenge for single-channel images like those in the MNIST dataset.
To compute the FID score for single-channel MNIST images, one must convert them to three-channel format by duplicating the single channel across the RGB channels.
Steps to convert MNIST single-channel images to three channels include importing necessary libraries, loading the dataset, normalization, and using TensorFlow for FID score calculation.
Converting MNIST single-channel images to RGB format enables effective FID score computation, allowing better evaluation of GAN models and adherence to metric requirements.

Makefiles are older than Doom why are we still using them?

The use of 'make', an ancient build tool, is questioned in modern software development despite its historical significance and prevalence in numerous projects.
Make's syntax, characterized by intricate rules and the need for precise indentation, has made it a challenging tool to work with.
While modern alternatives like CMake exist, they often still rely on 'make' underneath the surface, maintaining its grip on certain development environments.
Although considered fragile and outdated, 'make' continues to be deeply embedded in various systems, especially in academia and monorepos.
Usage of 'make' persists due to its ubiquitous presence and simplicity in smaller projects, CLI tools, and legacy codebases.
Despite its limitations, 'make' remains a reliable choice for quick and efficient build setups without the overhead of complex configurations.
Modern development tools are aiming to surpass 'make' by offering better syntax, clearer documentation, and improved developer experiences.
The future of build systems may involve smart, context-aware tools that reduce manual efforts and improve productivity for developers.
Devs are seeking advancements in build tools that are more declarative, user-friendly, and automated, enhancing the efficiency of the build process.
While 'make' still has its place in certain scenarios, the evolution of build systems is inevitable, with a focus on creating tools tailored for modern development needs.
Ultimately, the choice of build tool depends on the specific requirements of each project, aiming to maintain efficient builds and developer sanity.
