The blog post reflects on the author's experience with using URLs as powerful tools for state management in front-end development. After needing to add SQL syntax highlighting using PrismJS, the author remembered that a URL could reconstruct their entire setup based on a previously saved configuration, highlighting its capability to store state and share settings without relying on databases or other storage methods. This realization leads to a discussion on how front-end engineers often overlook URLs as state management tools, instead opting for more complex solutions like global stores or caches.

The content discusses the concept of Symbol objects in Ruby, specifically focusing on the Symbol `:Fred`. It begins by defining a Symbol as a named identifier within the Ruby interpreter, highlighting that the same Symbol object is created for a given name or string throughout the program's execution, regardless of context. This is demonstrated with the example that `:Fred` remains the same object ID even when used in different contexts (as a constant, method, or class). The author reflects on their initial confusion regarding

The book explores the design and history of programming languages through the lens of control structures, which dictate program execution flow. It begins with early uses of "goto" in programming and the rise of structured programming in the 1960s, progressing to advanced control structures like generators and coroutines in imperative languages. It then examines functional languages, focusing on continuations, control operators, and contemporary topics like algebraic effects and effect handlers. Blending historical context, practical code examples, and theoretical insights, the

Application Performance Monitoring (APM) serves as a tool for developers to diagnose application slowness and enhance user experience. Traditionally, it involves collecting extensive data displayed through dashboards and request traces, targeting known issues like N+1 queries and slow third-party API calls. However, traditional APMs are often built to address previously identified problems, which can leave developers unprepared for unforeseen issues that modern applications encounter. These legacy solutions can overwhelm with data yet fail to provide insights during production failures, leading

The article discusses the broader trends in the job market, particularly the impact of artificial intelligence (AI) on employment for junior developers and early-career professionals. In October 2025, over 20,000 tech workers were laid off, indicating a continuing rise in layoffs, with junior roles being disproportionately affected. Companies are increasingly favoring senior professionals, who can manage AI systems, over junior and mid-level employees. This shift reflects a change in hiring values, prioritizing control over potential, and suggests

A recent discovery in the Android Carrier Config manager revealed a flag (KEY_INFLATE_SIGNAL_STRENGTH_BOOL) that allows mobile network operators to report signal strength as one bar higher than it actually is. This undocumented feature is accessible to operators like AT&T and Verizon, who have both enabled it on their networks. The motivation behind this flag remains unclear, but it raises concerns over transparency in network coverage claims alongside other misleading indicators, such as fake 5G flags. The author expresses skepticism about
