HTTP/2 is widely promoted as a faster replacement for HTTP/1.1, promising multiplexing, header compression, and better performance. Yet in real-world environments—especially mobile networks or unstable connections—HTTP/2 can be noticeably slower. This article focuses on one specific reason: how HTTP/2’s reliance on a single TCP connection interacts poorly with packet loss, and why this negates many of its theoretical advantages.

Why A/B Testing Often Rewards Worse User Experiences Instead of Better Ones
A/B testing is widely regarded as the gold standard for data-driven product decisions. Teams trust it to reveal what users prefer and to guide design improvements objectively. Yet many mature products slowly become more addictive, less satisfying, and harder to use—despite constant experimentation. This article examines a specific, structural problem in A/B testing: why it systematically favors short-term behavioral exploitation over long-term user value, even when experiments are run correctly.
Why Chronic Dizziness Persists Even When Scans Are Normal: Vestibular Hypofunction Explained
Chronic dizziness is one of the most frustrating symptoms for patients and clinicians alike. Many people undergo brain imaging, blood tests, and cardiovascular checks, only to be told that everything looks normal. Yet the sensation of unsteadiness, floating, or imbalance continues for months or even years. This article focuses on a specific and commonly missed cause: vestibular hypofunction. By examining how the vestibular system actually works and how compensation can fail, this article explains why chronic dizziness persists without visible abnormalities.
Why Some People Feel Worse the More They Exercise: The Physiology of Overtraining and Chronic Inflammation
Exercise is widely promoted as a universal solution for better health, mood, and energy. Yet a significant number of people report the opposite experience: persistent fatigue, poor sleep, low motivation, and increased illness despite regular training. This article examines the specific physiological mechanisms behind overtraining and exercise-induced chronic inflammation, explaining why “more exercise” can backfire and how the body’s stress systems become dysregulated.
Why Professional Cleaning Can Significantly Reduce Allergies While Regular Cleaning Often Fails
Many people clean their homes frequently yet continue to suffer from chronic nasal congestion, sneezing, itchy eyes, or unexplained fatigue. These symptoms are often attributed to weather, immunity, or genetics. In reality, indoor allergens—especially dust mites and their byproducts—are frequently the root cause. This article examines why ordinary household cleaning is often ineffective against allergens, how professional cleaning changes the indoor biological environment, and which mechanisms actually reduce allergic load rather than just visual dirt.
Why Adding More Database Indexes Can Make Queries Slower Instead of Faster
Indexes are commonly seen as a universal solution to slow database queries. When performance degrades, the instinctive reaction is often to add more indexes. Yet in many real systems, this approach leads to worse performance, higher latency, and unstable behavior. This article dives into the mechanics of how database indexes actually work, why excessive indexing backfires, and how index overload quietly degrades query execution rather than improving it.
How Recommendation Systems Quietly Reduce Exploration and Lock Users Into Narrow Behavior Patterns
Recommendation systems are designed to help users discover relevant content efficiently. Over time, however, many users notice that platforms begin to feel repetitive, predictable, and surprisingly narrow. This is not an accident or a flaw in implementation—it is a structural outcome of how modern recommendation systems are optimized. This article examines the specific mechanisms that cause exploration to shrink, how feedback loops form, and why these systems naturally converge toward behavioral lock-in.
Why You Feel Tired, Hungry, or Foggy After Eating: The Overlooked Mechanics of Insulin Resistance
Many people experience fatigue, brain fog, or renewed hunger shortly after eating, even when meals are not excessive. These symptoms are often attributed to poor sleep, stress, or lack of willpower. In reality, they frequently reflect early-stage insulin resistance—a metabolic dysfunction that develops quietly long before diabetes is diagnosed. This article examines how insulin resistance actually works, why it produces confusing daily symptoms, and why it is so commonly missed in routine medical care.
Why Your Website Still Feels Slow Even With Caching: A Deep Dive Into Browser and CDN Cache Behavior
Many websites enable caching but still suffer from slow load times, inconsistent performance, or unexpected cache misses. The problem is rarely “cache not enabled,” but rather how different caching layers—browser, CDN, and origin server—interact in practice. This article dives into the mechanics of HTTP caching, explaining why common configurations fail, how cache decisions are actually made, and where performance silently breaks down.
Why You Can Sleep for Eight Hours and Still Wake Up Exhausted: A Closer Look at Sleep Apnea
Many people assume that persistent fatigue is caused by stress, aging, or lack of sleep. However, a significant number of individuals sleep for adequate hours and still wake up feeling unrefreshed. One overlooked reason is sleep apnea, a condition that disrupts breathing during sleep and prevents the body from entering truly restorative rest. This article examines how sleep apnea works, why it often goes undiagnosed, and how it silently affects daily energy, cognition, and long-term health.
