Throttling and debouncing are solutions to prevent performance issues caused by excessive function calls, such as a browser suffering memory strain from hundreds or thousands of calls when a user scrolls a webpage with a mouse scroll event. To prevent performance degradation due to numerous calls, simply reduce the number of calls. Throttling controls the interval between calls, while debouncing groups multiple calls into a smaller number of calls.
When I first delved into web development, CORS was one of the initial challenges I encountered. CORS itself isn't an issue but a protocol that informs developers when a request doesn't adhere to its rules. It's a fundamental security component for web browsers. While linking external images for a blog doesn't pose a security risk, retrieving dynamic resources from external sources via AJAX calls like POST or PUT can alter server state, creating security vulnerabilities. Therefore, calls that modify server state (including client state changes via cookie headers) must be rigorously verified to ensure they are genuinely intended by the developer. Otherwise, malicious script injection into a blog could trigger unwanted AJAX calls to manipulate server resources on an external domain.
Both Chrome browser and Node.js utilize the renowned V8 JavaScript engine. Both, built upon a JavaScript engine, are referred to as JavaScript Runtime Environments. Simply put, they are environments where JavaScript code executes. So, what sets them apart? The Chrome browser environment provides all features a user needs in a browser, such as DOM manipulation related to rendering, external resource calls like AXIOS, and image processing, all via Web APIs. The Node.js server environment, on the other hand, provides an event queue, event loop (single-threaded), and worker thread configuration to handle numerous requests.
I encountered a peculiar bug where Spring Security session information intermittently vanished within a `parallelStream` introduced for parallel processing. Like 'Schrödinger's Cat,' the results varied with each refresh. This post delves into the cause of this phenomenon and explores the three strategies SecurityContextHolder uses to share session data in a multi-threaded environment.
In an era where LLM tools, which filter out conversational impoliteness and deliver refined responses, have become commonplace, are we truly engaging in more thoughtful conversations? This article examines the phenomenon of conversational ability, which should be honed through countless failures in real-time communication, degenerating due to reliance on external tools. It further explores the potential societal anxieties and shifts in generational behavioral patterns that this trend may bring.
Salary negotiation is more than just an exchange of figures; it's a strategic dance of psychological timing. This analysis explores why engaging in a gradual negotiation process from the initial stages of recruitment, rather than waiting until after a final offer (when candidates tend to adopt a more calculative stance), proves more efficient for companies and fosters a more honest sharing of resources.
The belief that all human actions can be regulated by a single legal system may be an act of hubris. This article offers a sharp analysis of the paradox of the rule of law faced by humanity, which, having escaped the hierarchical controls of the Middle Ages, has now embraced infinite modern freedom. It further examines the deepening social coercion and the demonization of others that arise under the guise of diversity.
From the tumultuous periods of the World Wars and the Industrial Revolution to the present day, human intellectual history has developed brilliantly, yet philosophy seems to remain rooted in the legacy of the past. Today, as the temperature of social conflict crosses a critical threshold, this essay questions why new philosophical insights that truly resonate with our times have not emerged.
The advent of Large Language Models (LLMs) has dramatically accelerated development speed, yet paradoxically, our patience for truly delving into and sticking with tasks has dwindled. In an age where there's an intense focus on immediate results, this piece captures a personal reflection and training journey to reclaim consistency and the ability to wait through the 'slow act' of writing.
