Understanding and Solving False Sharing in Multi-threaded Applications with an actual issue I had

stp2y0 CommentsNewsc, coding, community, computerscience, development, engineering, inclusive, opensource, programming, software

Recently, I was working on a multi-threaded implementation of a function to calculate the Poisson distribution (amath_pdist). The goal was to divide the workload across multiple threads to improve performance, especially for large arrays. However, instead of achieving the expected speedup, I noticed a significant slowdown as the size of the array increased. After some investigation, I discovered the culprit: false sharing. In this post, I’ll explain what false sharing is, show the original code causing the problem, and share the fixes that led to a substantial performance improvement. The Problem: False Sharing in Multi-threaded Code False sharing happens when…

Sufficient Software Tests Using Metrics

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, software, tests

The primary goal of software testing is to prevent bugs and defects from reaching end users. Effective testing ensures that the software is reliable, functional, and meets the specified requirements, enhancing user satisfaction. However, simply knowing how much of the code is executed (or covered) by tests is not enough. Testing metrics provide insight into how effective tests are, and whether the software system is tested sufficiently. The code coverage metric measures the percentage of code executed during testing but does not account for the quality of those tests. We need to have a combination of different metrics to evaluate…

Push Back on Whiteboard Tests

stp2y0 CommentsNewscareer, coding, community, development, engineering, hiring, inclusive, interview, software

With the rise of ghost jobs and startups' unrealistic expectations, it's time for Senior and Mid-Level Devs to push back on whiteboard tests. Whiteboard Tests Not Suitable for Senior Devs If you are a Senior Dev, you probably have plenty of experience and plenty of projects that you worked on. Companies should have no excuse to keep on the circus of technical rounds at this point except maybe situational or behavioral assessments which is a different story. I've often been interviewed by companies, and every time I push back on whiteboard tests, I got either rejected or they look at…

You’re Doing Error-Handling Wrong!

stp2y0 CommentsNewscoding, community, development, discuss, engineering, inclusive, javascript, programming, software, typescript

You’re Doing Error-Handling Wrong: A Case for Predictable and Standardized Responses Introduction: An Opinionated Stance Error handling in JavaScript is a topic that evokes strong opinions, and I’m here to share mine: the traditional try-catch approach is clunky, inconvenient, and outdated. At Garmingo, where we built Garmingo Status — a SaaS solution for uptime and infrastructure monitoring—we’ve shifted away from try-catch blocks. Instead, we embraced a TypeScript-based approach that provides predictable, standardized responses for asynchronous operations. This article shares why we believe this paradigm is a game-changer for developer productivity and how it helped simplify our codebase. While it’s an…

AI-Based Vulnerability Scanning for Cloud Infrastructure

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, software

AI-Based Vulnerability Scanning for Cloud Infrastructure: A New Era in Security The rapid adoption of cloud computing has brought about numerous advantages for organizations, including scalability, cost-efficiency, and increased agility. However, this shift has also introduced new security challenges, particularly regarding the identification and mitigation of vulnerabilities within complex and dynamic cloud environments. Traditional vulnerability scanning methods often struggle to keep pace with the evolving threat landscape and the ephemeral nature of cloud resources. This is where AI-based vulnerability scanning emerges as a crucial component of modern cloud security strategies. The Limitations of Traditional Vulnerability Scanning: Traditional vulnerability scanners typically…

LeetCode Meditations: Longest Increasing Subsequence

stp2y0 CommentsNewsalgorithms, coding, community, computerscience, development, engineering, inclusive, javascript, software, typescript

The description for this problem simply states: Given an integer array nums, return the length of the longest strictly increasing subsequence. For example: Input: nums = [10, 9, 2, 5, 3, 7, 101, 18] Output: 4 Explanation: The longest increasing subsequence is [2, 3, 7, 101], therefore the length is 4. Enter fullscreen mode Exit fullscreen mode Or: Input: nums = [0, 1, 0, 3, 2, 3] Output: 4 Enter fullscreen mode Exit fullscreen mode Or: Input: nums = [7, 7, 7, 7, 7, 7, 7] Output: 1 Enter fullscreen mode Exit fullscreen mode Similar to the previous problem in…

Note: This is the second part of our series on the MVVM architecture in the frontend. If you haven’t read the first part yet, we highly recommend starting here. Bridge Pattern Coding Example In the first part of this series, we discussed how the Bridge Pattern can enhance the reusability and maintainability of UI components in a large-scale frontend application. While we focused primarily on the high-level design with uml class diagrams, the real challenge lies in its implementation. After all, even the best designs are merely theoretical without effective implementation. Example: A Reusable Button Component Let’s walk through a…
