Skeleton loading screen design — How to improve perceived performance

A skeleton loading screen is a UI design technique that mimics the final interface structure with placeholders to indicate loading state.
It improves perceived performance by showing users how data segments will appear before fully loaded.
Skeleton screens differ from preloader animations and progress bars by providing a preview of the page layout.
They engage users by revealing content progressively and using animations like pulsating effects.
Benefits of skeleton screens include improving perceived performance, creating an engaging loading state, and ensuring a seamless transition to the loaded state.
Challenges include increased design and development time, but designers can simplify by using prototyping tools and libraries.
Types of skeleton loading screens include static, animated, and frame-display variations.
Examples from Facebook, Uber, and eBay showcase well-designed skeleton loading screens in real-world applications.
Best practices suggest keeping layout consistent, incorporating motion effects, using container-based components, and proper accessibility features.
Skeleton loading screens are preferred over preloader animations and progress bars for user engagement, perceived performance, and loading structured content.

Why typography still matters in UX design

Typography is a crucial aspect of website and application design, going beyond just choosing fonts.
It plays a significant role in user experience (UX) by conveying messages attractively and readably.
Typography has a rich history dating back to the early days of printing, with advancements like the Gutenberg Press.
In the digital age, typography evolved with technologies like electronic typesetting and digital typefaces.
Key developments include the adoption of OpenType format and Web Open Font Format (WOFF) for web use.
Typography terminology includes understanding 'type' as design and 'font' as the actual file used for application/printing.
Serif and sans serif are two main type classifications, each conveying different visual styles.
Typography contributes to UX by enhancing legibility, expressiveness, and accessibility for users.
Essential aspects of typography in design include controlling typefaces, clarity, scannability, and alignment with brand identity.
Choosing the right typography from the start of the design process is crucial for successful UX implementation.

How to design a multithreaded program in Java — Part 1: Basic Concepts and first steps

Multithreading can be challenging, but this guide breaks down the basics to help you understand key concepts and terminology to design multithreaded applications effectively. Understanding how processors, threads, processes, and the OS scheduler work is fundamental for optimal performance.
Java threads abstract OS or platform threads and require additional resources like memory. Thread sharing of resources within a process in Java necessitates synchronization to avoid resource corruption.
Distinguishing between CPU-bound and I/O-bound programs is crucial for design decisions. Programs dependent on CPU performance are CPU-bound, while those reliant on I/O system performance are I/O-bound.
In multithreading design, optimizing for CPU-bound programs involves minimizing context switches, whereas I/O-bound programs benefit from more threads to handle blocking operations effectively.
Understanding blocking and non-blocking operations is essential for efficient CPU utilization. Non-blocking operations help maximize CPU efficiency by allowing threads to continue working while waiting for tasks.
Concurrency and parallelism differ: parallelism requires multiple processors running tasks simultaneously, while concurrency involves a single processor switching between tasks. Knowing when to apply each is vital for program optimization.
Thread safety ensures data integrity when shared among threads. Immutable objects inherently support thread safety, while synchronization techniques are needed to protect shared mutable resources.
Amdahl’s Law guides the potential performance improvements of parallel programs based on parallelizable code portions and available processors. Consider the trade-offs for speedup with parallel execution.
Designing high-performance multithreaded programs involves strategic parallelization and task decomposition. Identifying scalable parallelization opportunities and optimizing tasks for concurrent execution are key steps.
Understanding how to convert sequential tasks into parallel tasks efficiently and leveraging concepts like Amdahl’s Law can lead to significant performance gains in multithreaded programs.
Starting with a serial version and incrementally optimizing for parallel execution is beneficial in designing efficient multithreaded programs. Embracing best practices and concepts like thread safety enhances program scalability and performance.

TypeScript is going Go: Why it’s the pragmatic choice

The article discusses the porting of TypeScript to Go known as 'TypeScript 7' and reflects on the thoughts of two individuals in the TypeScript community.
The decision for the Go port was driven by the need for performance improvements that other tools in the JavaScript ecosystem were demonstrating.
The port to Go focused on enhancing the speed of the type checker, compiler, and language services, leading to faster feedback and builds for developers.
TypeScript’s compiler will no longer be written in TypeScript but in Go, marking a shift in the development process.
Concerns about reduced TypeScript usage by the team and its impact on community feedback and TypeScript’s influence on JavaScript evolution are addressed in the article.
The article also explores the implications on interacting with TypeScript via its CLI, JavaScript API, language server, and other tools within the ecosystem.
Tools like ts-loader and ts-blank-space may need adjustments due to internal API changes, while TypeScript-eslint is expected to benefit from the performance enhancements.
The choice of Go over other languages like C# or Rust for the TypeScript port is attributed to Go's pragmatic nature and its alignment with TypeScript's ethos.
The article also delves into the implications of JavaScript's performance for implementing a type checker and the speed gains achieved through the TypeScript to Go port.
In conclusion, the article emphasizes the importance of performance in the ecosystem and expresses optimism about the TypeScript team's approach towards the migration.

Reactive Forms vs Template-Driven Forms in Angular: When to Use What

Reactive Forms and Template-Driven Forms are two approaches for building forms in Angular.
Template-Driven Forms rely on Angular directives in the component's HTML template and handle most of the form control logic there.
Reactive Forms are built programmatically in the component class using FormControl, FormGroup, and FormBuilder, offering more control and predictability.

How to Exit Loops Early With the Python Break Keyword

The break statement in Python lets you exit a loop prematurely, transferring control to the code that follows the loop.
Using break outside of loops doesn’t make sense because it’s specifically designed to exit loops early.
The break statement doesn’t exit all loops, only the innermost loop that contains it.
You can use the break statement to exit a loop early and prevent unnecessary iterations.

2537. Count the Number of Good Subarrays

Given an integer array nums and an integer k, return the number of good subarrays of nums.
A subarray arr is good if there are at least k pairs of indices (i, j) such that i < j and arr[i] == arr[j].
The approach to solve this problem efficiently involves using a sliding window technique combined with a hash map to track the frequency of elements within the current window.
This approach efficiently counts all valid subarrays in linear time, O(n), by ensuring each element is processed at most twice (once added and once removed from the window).
