LeetCode Grind: A Job Search Failure Story

2025-01-09

A cloud engineer, laid off after Weaveworks' bankruptcy, focused heavily on LeetCode preparation, neglecting crucial skills like distributed systems, Kubernetes internals, and system architecture. This led to poor interview performance. He learned that practical skills and problem-solving abilities are more valuable than algorithm proficiency alone; LeetCode grinding isn't a guaranteed path to employment.

SQL NULLs: Breaking Your Intuition

2025-01-09

SQL's treatment of NULL values often defies expectations. This post reveals the surprising behavior of NULLs in unique constraint columns: multiple NULLs can coexist. Through practical examples in SQLite, Postgres, and MySQL, the author demonstrates how NULLs behave differently with the '=' and 'IS' operators, explaining the underlying reasons. Two solutions for ensuring uniqueness are explored: creating a generated column and using a partial index. Using a partial index is recommended as best practice, avoiding table size increases and potential errors.

The iPhone Performance Illusion: A Stark Reality Check for Web Developers

2025-01-09

This article exposes a significant performance gap in mobile web applications. Using data from Rum Archive, the author compares UK iOS and Android users' web page loading speeds, revealing Android users experience 34% slower First Contentful Paint (FCP) and a staggering 66% slower Time To Interactive (TTI). Analyzing the correlation between GeekBench CPU scores and Interaction to Next Paint (INP), the author shows that low-end Android devices exhibit significantly higher INP times than high-end devices, with even older iPhones outperforming the latest top-tier Android phones. The author stresses that the large Android user base shouldn't be ignored; neglecting their experience leads to lost opportunities. The article urges developers to understand user device diversity, use RUM tools to gain insights into real-world conditions, and simulate low-end devices during development and testing to create more inclusive web apps.

Serverless Computing: Why Haven't We All Switched Yet?

2025-01-09

Despite the appealing value proposition of serverless computing (e.g., AWS Lambda)—pay-per-use, auto-scaling, and abstraction from infrastructure—widespread adoption remains slow. The author points to two primary reasons: the lessons learned from the challenging microservices migration, where many organizations struggled due to insufficient technical and organizational readiness; and the fact that serverless amplifies existing challenges of microservices, such as complexities in dependency injection and observability. A gradual adoption approach focusing on highly autonomous teams and suitable use cases (like AI and LLM integrations) is suggested as a more efficient strategy.

Poka-Yoke: The Japanese Art of Mistake-Proofing

2025-01-09

Poka-yoke, meaning "mistake-proofing" in Japanese, is a lean manufacturing concept originating from the Toyota Production System. It involves designing mechanisms to prevent, correct, or highlight human errors in a process, thereby eliminating defects. A simple example is a car's clutch pedal—it's a poka-yoke, forcing the driver to depress it before starting the engine. This approach not only improves product quality but also reduces training costs, lessens quality control burdens, and ultimately achieves 100% built-in quality control.

Double-Keyed Caching: How Browser Cache Partitioning Reshaped the Web

2025-01-09

To enhance privacy, browser caching has shifted from a simple key-value store to double-keyed caching (or cache partitioning). This fundamentally changes how resources are cached: previously shared across sites via public CDNs, now each site maintains its own copy. While bolstering privacy by preventing cache probing, timing attacks, etc., this leads to lower cache hit rates and increased network load. The article analyzes this impact on various resources (shared libraries, fonts, large models), proposing solutions like domain consolidation, module federation, and smart resource loading. The era of shared public CDNs may be ending, but the web's adaptability will prevail.

Challenging the CAP Theorem: A Partial Progress Conjecture Under Asynchrony

2025-01-08

A new paper challenges the well-known CAP theorem. The authors conjecture that partial progress is possible under network partitions, meaning the system can remain responsive to a subset of clients and achieve non-zero throughput during failures. They present the design of their CASSANDRA consensus protocol, allowing partitioned replicas to order client requests, potentially offering a path to systems that are both consistent and available to some degree, even during partitions. This research offers a novel approach to building more robust distributed systems.

The Ratchet Effect: How Engineers Build Reputation at Big Tech

2025-01-08

Engineer reputation at large tech companies isn't solely about technical skill; it's a gradual process. Starting with low-level tasks, engineers build trust and gain access to higher-profile projects through consistent success. This "ratchet effect" makes reputation slow to change. Even mistakes can be overcome with continued delivery. However, repeated failures lead to a downward spiral. The author advises new hires to focus on smaller projects to build a solid reputation, avoiding risky attempts to jump to high-profile work immediately.
