I’ll tell about new best practices of large Node.js apps, which allow to increase throughput by 10X times (with demo).
The growth of functionality in Enterprise applications often leads to a decline in throughput. We start with the dispersion of the Main Thread and spread it into a spectrum of operations. We learn which of these operations we can offload from the Main Thread to threads/workers/processes, and how to do that. We select successful ways of parallelization for each type of operation, consider the benefits and limitations. Compare the throughput after the Main Thread decomposition.
This document summarizes key aspects of fast JavaScript virtual machines (VMs) like V8, with a focus on Google's V8 VM. It discusses the challenges of optimizing JavaScript given its dynamic nature. The V8 VM addresses this through techniques like hidden classes to group similar objects, compilation to native code with inline caching, and efficient generational garbage collection. Hidden classes allow optimizing object property access like in static languages. Inline caching handles dynamic property lookups at runtime. Memory is managed through precise generational garbage collection across multiple generations and memory spaces. These techniques allow V8 to optimize JavaScript and achieve fast performance for large programs.

Modular Monolith - a Practical Alternative to Microservices @ Devoxx UK 2024Victor Rentea
The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions.

The promise of DevOps is that we can push new ideas out to market faster while avoiding delivering serious defects into production. Andreas Grabner explains that testers are no longer measured by the number of defect reports they enter, nor are developers measured by the lines of code they write. As a team, you are measured by how fast you can deploy high quality functionality to the end user. Achieving this goal requires testers to increase their skills. It’s all about finding solutions—not just problems. Testers must transition from reporting “app crashes” to providing details such as “memory leak caused by bad cache implementation.” Instead of reporting “it’s slow,” testers must discover “wrong hibernate configuration causes too much traffic from the database.” Using three real-life examples, Andreas illustrates what it takes for testing teams to become part of the DevOps transformation—bringing more value to the entire organization.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.
