STORAGE CHALLENGES IN THE EVOLUTION OF DATABASE ARCHITECTURE

A team of Postman engineers tackled a storage issue with the Sync service, which had been running since 2014 and was facing physical storage limitations on an AWS RDS Aurora cluster. The team initially attempted to prune older records to free up space but found that it didn't work as expected due to certain constraints. They then devised an approach to free up tables without compromising system reliability, resulting in 60TB of space freed.

SPEEDING UP YOUR CODE WHEN MULTIPLE CORES AREN’T AN OPTION

Parallelism is the practice of using multi-threading or multiprocessing to take advantage of multiple CPU cores for improved performance. There are still many optimizations you can make to lower-level code when parallelism isn’t available. This article explores various optimizations, including simplifying rounding operations, reducing memory usage by reusing arrays, and minimizing conditional statements.

OPEN SOURCE DOES NOT WIN BY BEING CHEAPER

In the world of open source software, it's not enough for a project to simply position itself as an open-source alternative to a commercial product. To succeed, open-source companies must have a clear reason for being open source or surpass their competitors. Projects like PostHog, Medplum, and Minio succeed by providing transparency and trust in data handling, while others thrive by allowing community-driven integrations and enhancements, ultimately striving to be better than closed-source alternatives.

HOW LINEAR BUILDS PRODUCT

Unlike many tech companies, Linear doesn't employ product managers or cross-functional teams. Instead, it has a single head of product. Rather than setting metric-based goals, it prioritizes a company-wide north-star objective. In contrast to common practice, it doesn't rely on A/B testing for decision-making. Furthermore, its hiring process includes a paid work trial, and the company operates entirely remotely. Impressively, Linear has maintained profitability for over two years, spent a mere $35,000 on marketing, and experienced minimal employee turnover.
