Everything I Ever Learned About JVM Performance Tuning @Twitter
Everything I Ever Learned About JVM Performance Tuning @Twitter The document outlines JVM performance tuning strategies, with a focus on reducing latency caused primarily by garbage collection. It covers various areas of optimization including memory footprint, lock contention, CPU usage, and I/O tuning, while highlighting the drawbacks of heavy frameworks like Thrift. Key strategies involve caref
Glossary
algebraic data type A type defined by providing several alternatives, each of which comes with its own constructor. It usually comes with a way to decompose the type through pattern matching. The concept is found in specification languages and functional programming languages. Algebraic data types can be emulated in Scala with case classes. alternative A branch of a match expression. It has the fo
Scala’s parallel collections « Otaku – Cedric's blog
Scala 2.9 introduced parallel collections, which mirror most of the existing collections with a parallel version. Collections that have been parallelized this way have received a new method called par which magically parallelize certain operations on this collection. For example, here is a sequential version: scala> (1 to 5) foreach println 1 2 3 4 5 And the parallel version (notice the extra par
Twitter Shifting More Code to JVM, Citing Performance and Encapsulation As Primary Drivers
Effective Practices for Coding with a Chat-Based AI In this article, we explore how AI agents are reshaping software development and the impact they have on a developer’s workflow. We introduce a practical approach to staying in control while working with these tools by adopting key best practices from the discipline of software architecture, including defining an implementation plan, splitting ta
