MICROBENCHMARKS ARE EXPERIMENTS

A benchmark comparing Dart and JavaScript code initially showed JavaScript as faster, but this discrepancy was resolved by making sure equivalent data structures (Int64List in Dart) were used. Further investigation revealed that Dart's interrupt checks impacted performance negatively, while JavaScriptCore's optimizations, including modulo strength reduction, contributed to its speed advantage, which was negated by one-line code change in Dart that took advantage of Dart's compiler.

HOW LINKEDIN SCALED THEIR SYSTEM TO 5 MILLION QUERIES PER SECOND

LinkedIn scaled its restriction enforcement system to handle 5 million queries per second using a multi-faceted approach. It used BitSets for efficient boolean storage and Bloom Filters for probabilistic set membership checks. Its final architecture incorporated a Venice database as the central source of truth, Kafka for near real-time updates, and a client layer utilizing a REST API.

BUILDING REDDIT'S FRONTEND WITH VITE

Reddit was experiencing slow Rollup-based frontend build times, averaging nearly two minutes for initial builds and 40 seconds for incremental ones. To address this, it adopted Vite, a build tool using ESBuild's JIT compilation. The migration resulted in build times under one second for both initial and incremental builds.

HOW TO BURNOUT A SOFTWARE ENGINEER, IN 3 EASY STEPS

Burnout isn't always caused by working long hours. Often, it's caused by deeper issues during engineering. This author tells two stories about burning out in the same way at both a startup and a big tech company. The burnout was caused by micromanagement, a lack of trust in engineers, the introduction of unnecessary processes, not shipping code to customers, and overpromising.

WEAPONIZING SSO FOR PROFIT

Many SaaS vendors are charging extra for Single Sign-On (SSO), which is increasingly mandated by regulations like NIS2 and DORA. This practice forces companies, particularly regulated ones, into higher, more expensive pricing tiers to meet security and compliance requirements, despite SSO's relatively low implementation cost.

DESIGNING (AND EVOLVING) A NEW WEB PERFORMANCE SCORE

CrRRUX is a relative-ranking score designed to simplify competitor analysis by aggregating Core Web Vitals data (LCP, INP, and CLS) into a single comparative score. The score accounts for “passingness”, continuity, and real user experiences. It can be automated through Google Sheets and the CrUX API.

STRUCTURED EDITING AND INCREMENTAL PARSING

Structured editing is a method where code editors understand a program's syntax, offering benefits like instant feedback and accurate selections. Structured editors often restrict non-structural editing, which frustrates many programmers who frequently edit code in ways that violate its syntax. A solution to this is incremental parsing, which allows for both structured understanding and free-form editing by maintaining a parse tree in the background, even if the code becomes temporarily invalid.
