NodeJS is an event-driven JavaScript platform for building real-time web applications. It was first released in 2009 and excels at tasks that require interaction with the website like chat applications or location tracking, but is not well-suited for CPU intensive tasks. NodeJS uses an event loop, callbacks, and threads managed by a scheduler to run code asynchronously and handle multiple requests concurrently without blocking. Developers should change their code to an asynchronous programming style when using NodeJS, which is well-suited for IO heavy applications but not CPU heavy applications. Dependencies and applications can be installed via the Node Package Manager (NPM).

What is NodeJS?
• Event Driven platform for JavaScript
• First released in 2009
• Good for real-time interaction with a website
– Chat applications
– Location tracking
• Bad for CPU intensive tasks
– Predicting the weather

Threads and Scheduling
• Smallest sequence of executable code
• Run multiple threads together via
multithreading
• Threads block
• Threads are managed by a Scheduler

Tradition Webserver Example
• Request blog post
• Call to database for post
• Build HTML
• Send response

Event Loop
Taken from: http://misclassblog.com/

How to Code
• Change to only asynchronous programming
Taken from: Matt Perpick, “Writing Asynchronous JavaScript 101”

When to Node
• IO heavy applications
• NOT CPU heavy applications

NPM
• Node Package Manager

Building a Multithreaded Web-Based Game Engine Using HTML5/CSS3 and JavaScrip...Corey Clark, Ph.D.

As hardware developer’s push away from creating faster processors in lieu of multicore architectures game developers have to leverage multithreading technologies to capitalize on these new devices. With multicore mobile devices the need for a multithreaded web based game engine is a reality. This talk will discuss design of various multithreaded web engine architectures. Two specific threading implementations will be discussed. First technique shows how to create a static thread that is registered with the engine with the same techniques as other loaded resource. A second technique will focus on using a Thread Controller, which has the ability to create dynamic generic threads that can be passed functions during run time and process them in parallel. This also allows for coupling threaded commands together thereby creating critical sections and other common multithreading techniques utilized in C++ coding. Focus will also be placed on design consideration and operation performance. An example will be show that demonstrates how the proper coding style and data structures can make or break your design. Also timing and performance standards will be given for various browsers so users can understand the overall overhead and operational considerations that need to be considered when using threads in a browser based environment. Technology and capability limitations will also be discussed so developers can understand the differences between multithreading in C++ native applications and JavaScript browser-based application. This will also include some tricks on how to design an architecture that allows for some workarounds. Other JavaScript APIs such as WebGL, and WebSockets will also be discussed and demonstrated to help show the full realization of a web based game engine. Coding samples and architectural layouts will be shown to the audience to help drive home the concepts being discussed during the lecture. A functional HTML5 JavaScript Multithreaded Web Engine will be demonstrated during the lectured to show the overall functionality and performance of the techniques described. A summary write up of a sample engine architecture is attached in the supplemental documents that gives a brief description and architectural figures. These will be integrated into the lecture to help visualize some of the concepts being discussed.

Succession “Losers”: What Happens to Executives Passed Over for the CEO Job? Stanford GSB Corporate Governance Research Initiative

This document summarizes a study of CEO succession events among the largest 100 U.S. corporations between 2005-2015. The study analyzed executives who were passed over for the CEO role ("succession losers") and their subsequent careers. It found that 74% of passed over executives left their companies, with 30% eventually becoming CEOs elsewhere. However, companies led by succession losers saw average stock price declines of 13% over 3 years, compared to gains for companies whose CEO selections remained unchanged. The findings suggest that boards generally identify the most qualified CEO candidates, though differences between internal and external hires complicate comparisons.

Explaining GitHub Actions Failures with Large Language Models Challenges, In...ssuserb14185

GitHub Actions (GA) has become the de facto tool that developers use to automate software workflows, seamlessly building, testing, and deploying code. Yet when GA fails, it disrupts development, causing delays and driving up costs. Diagnosing failures becomes especially challenging because error logs are often long, complex and unstructured. Given these difficulties, this study explores the potential of large language models (LLMs) to generate correct, clear, concise, and actionable contextual descriptions (or summaries) for GA failures, focusing on developers’ perceptions of their feasibility and usefulness. Our results show that over 80% of developers rated LLM explanations positively in terms of correctness for simpler/small logs. Overall, our findings suggest that LLMs can feasibly assist developers in understanding common GA errors, thus, potentially reducing manual analysis. However, we also found that improved reasoning abilities are needed to support more complex CI/CD scenarios. For instance, less experienced developers tend to be more positive on the described context, while seasoned developers prefer concise summaries. Overall, our work offers key insights for researchers enhancing LLM reasoning, particularly in adapting explanations to user expertise. https://arxiv.org/abs/2501.16495

What Do Contribution Guidelines Say About Software Testing? (MSR 2025)Andre Hora

Software testing plays a crucial role in the contribution process of open-source projects. For example, contributions introducing new features are expected to include tests, and contributions with tests are more likely to be accepted. Although most real-world projects require contributors to write tests, the specific testing practices communicated to contributors remain unclear. In this paper, we present an empirical study to understand better how software testing is approached in contribution guidelines. We analyze the guidelines of 200 Python and JavaScript open-source software projects. We find that 78% of the projects include some form of test documentation for contributors. Test documentation is located in multiple sources, including CONTRIBUTING files (58%), external documentation (24%), and README files (8%). Furthermore, test documentation commonly explains how to run tests (83.5%), but less often provides guidance on how to write tests (37%). It frequently covers unit tests (71%), but rarely addresses integration (20.5%) and end-to-end tests (15.5%). Other key testing aspects are also less frequently discussed: test coverage (25.5%) and mocking (9.5%). We conclude by discussing implications and future research.

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik

This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements. Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows. We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure. The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.
