How Combining GSAP and Lenis Solves Choppy Scroll Animation on the Web

Web developers often struggle with inconsistent scroll animations because native browser scroll delivers position data in discrete jumps rather than a smooth stream, causing stuttering across different devices and input methods. GSAP's ScrollTrigger reads these raw scroll events directly, meaning any instability in the input is inherited by the animation output. Lenis, a smooth scroll library, addresses this by intercepting raw scroll input and interpolating it into a continuous, eased value before applying it to the page. This gives ScrollTrigger a stable, predictable data source to animate against, producing the fluid, high-end feel seen on award-winning websites. The GSAP-plus-Lenis combination has become a go-to setup for developers building scroll-driven animations on professional client projects.

Why a 90% vs 92% Robot Policy Win Rate Means Less Than You Think

A technical analysis published on DEV Community warns that comparing robot control policies using raw success-rate percentages alone is statistically unreliable. Without reporting sample sizes, confidence intervals, and statistical power, a difference such as 90% versus 92% cannot be taken as proof that one policy outperforms another. The RoboLab v4 benchmark highlights the problem: with only 10 episodes per task, a 90% success rate carries a 95% confidence interval spanning roughly 19 percentage points. The article recommends reporting raw counts in k/n form and using methods like Clopper-Pearson intervals and McNemar's paired testing for valid comparisons. Resolving a true 2-percentage-point difference near the 90% success level typically requires thousands of roll-out trials, far beyond what most benchmarks currently provide.

Why Name-Based Disk Cleanup Scripts Can Silently Delete Important Files

Developers commonly use shell scripts with rm -rf to delete build directories like node_modules, target, and build, relying solely on folder names to identify what is safe to remove. However, directory names are not reliable indicators of contents — many projects legitimately reuse common names like target or build for entirely different purposes, including hand-built assets or deployment files. In some cases, build output is intentionally committed to version control because the build is not reproducible on every machine, meaning a name-based deletion can permanently destroy the only copy of critical files. These scripts also risk following symlinks into unintended external volumes, potentially wiping shared dependency caches used across multiple projects. Native build tool commands such as cargo clean are safer alternatives, as they use their own metadata to identify exactly what they created rather than guessing by name.

AWS-Based Enterprise RAG System Combines Hybrid Search and Bedrock for Scalable AI

Developer Ved Prajapati has outlined an enterprise-grade Retrieval-Augmented Generation (RAG) architecture built on AWS, designed to ground generative AI responses in external, organisation-specific knowledge. The system leverages Amazon Bedrock and Titan Embeddings for vector generation, and pairs semantic vector search with keyword-based retrieval through a hybrid search strategy. A FastAPI layer exposes application functionality, while workloads run on Amazon EKS with a React frontend. Rather than treating RAG as a simple vector similarity problem, the architecture breaks the pipeline into independently optimisable stages — including document ingestion, chunking, embedding, ranking, and context construction. The design aims to improve retrieval quality and scalability for production AI applications on cloud-native AWS infrastructure.

Developer builds offline Mac app to capture, read, and translate screenshots in one tool

A developer frustrated with switching between multiple apps to translate Korean game dialogues built a single macOS utility called iShot to streamline the process. The app, written in Pure Swift and SwiftUI, can capture screenshots, extract text, and translate foreign-language images entirely offline without any network calls. It uses Apple's Vision framework for on-device text recognition, keeping sensitive screenshot content — such as API keys or personal chats — local to the user's Mac. Additional features include full-page image stitching, screen recording with a camera bubble overlay, and a single hotkey interface. The developer released a public trial and is seeking feedback on how users currently extract text from screenshots to guide future development.

Sonny Ramadhin: The Indian-Origin Cricketer Who Made History for West Indies at Lord's

Sonny Ramadhin was born in St Charles Village, Trinidad, near the capital Port of Spain. He lost both his parents at a very young age and was subsequently raised by his grandparents. His grandparents were of Indian origin, having migrated to Trinidad to work on cocoa estates. Ramadhin went on to become the first cricketer of Indian origin to represent the West Indies, famously playing a decisive role against England at Lord's in 1950.

CNG, EVs and Hybrids Together Cross 42% of India's Car Sales for First Time

Alternative fuel vehicles have collectively surpassed petrol cars in Indian passenger vehicle sales for the first time, claiming over 42% market share. CNG vehicles hit a record 25% share in August, while electric vehicle sales surged 52% year-on-year. Hybrid vehicles also contributed to the shift away from conventional petrol-powered cars. Tata Motors reclaimed its top spot in the domestic EV segment during this period. Delhi emerged as the city with the highest electric car penetration, driven largely by fleet registrations.

GTA 6 Leaker CyberLeek Allegedly Earned Up to $300K via Meme Coin Scheme

A leaker known as CyberLeek reportedly profited between $250,000 and $300,000 by capitalizing on the buzz surrounding the GTA 6 leaks. The individual launched a meme coin whose market capitalization climbed to $22 million, driven by heavy trading activity. Rather than selling tokens directly, CyberLeek generated income through transaction fees. The leaker now faces potential legal consequences, as GTA 6 publisher Take-Two Interactive is reportedly considering legal action against them.

Sachin Tendulkar Launches Fellowship in Father's Memory to Support Young Doctors

Cricket legend Sachin Tendulkar honoured his late father, Ramesh Tendulkar, on Teachers' Day by establishing a memorial fellowship in his name. The Professor Ramesh Tendulkar Memorial Fellowship is designed to support young doctors specialising in cleft and craniofacial care. The initiative reflects the elder Tendulkar's belief in education as a pathway to opportunity. The fellowship is part of broader efforts by Sachin's foundation, which also runs programmes in sports, healthcare, and children's education.

AWS Labs Launches Nx Plugin to Automate Full-Stack AWS App Scaffolding

AWS Labs has released an open-source Nx plugin (@aws/nx-plugin) designed to eliminate repetitive boilerplate when building full-stack applications on AWS. The tool uses code generators built on top of the Nx monorepo toolkit, allowing developers to scaffold production-ready application code along with infrastructure definitions in CDK or Terraform via a simple CLI. It supports common AWS components including Lambda APIs, API Gateway, Cognito authentication, and frontend websites, letting teams add pieces incrementally rather than committing to a single rigid template. All generated code lives directly in the developer's repository as editable source files, with no hidden framework layer. The plugin was in a pre-1.0 release candidate phase at the time of writing, with active updates being published to npm.

Haryana Electoral Roll Drive Reunites Brothers Separated for 35 Years

Two brothers in Haryana have been reunited after being separated for 35 years, thanks to a routine electoral roll verification exercise. The Special Intensive Revision (SIR) drive, aimed at updating voter registration records, led to the unexpected reconnection. A phone call made during the verification process turned out to be the key moment that brought the siblings back together. The reunion highlights an unintended but significant human outcome of the state's voter roll update campaign.

One 'Video Not Playing' Bug Was Actually Four Separate Problems

A development team shipping long-form video lessons discovered that a single recurring complaint — 'video not playing' — traced back to four distinct, unrelated technical issues. Buffering failures on poor mobile connections were worsened by default ExoPlayer settings tuned for general media rather than 40-minute educational streams, prompting the team to increase buffer durations and add honest reconnection messaging. DRM decryption errors were caused by a server-side token and content-packaging mismatch, not client code, while separate TLS handshake failures were misleadingly surfaced inside DRM error fields. The team found that methodically reading exact error codes and cause strings — rather than inferring from symptoms — was the key to untangling problems that looked identical on the surface. A core takeaway was that perceived reliability mattered more than video quality for learners, with students preferring steady 480p playback over high-definition video that buffered frequently.

Schrödinger's Equation: The Physics Formula Nobody Fully Understands

Erwin Schrödinger developed his famous quantum wave equation during a mountain retreat, a formula that now underpins much of modern physics and technology. Despite its practical success, physicists and philosophers have long debated what the equation actually implies about the nature of reality. The thought experiment of Schrödinger's cat — simultaneously dead and alive until observed — illustrates the deep conceptual puzzles at the heart of quantum mechanics. These questions are not merely academic, as interpretations of quantum theory influence fields ranging from computing to cosmology. Understanding the debate matters because it shapes how scientists and thinkers conceive of existence, observation, and the fundamental fabric of the universe.

How to Test Infrastructure as Code Using tflint, Checkov, and Terratest

A technical guide published on DEV Community outlines three complementary layers for testing Infrastructure as Code (IaC) before deploying to production. The first layer uses tflint for static analysis, catching syntax errors and provider-specific issues in seconds without requiring cloud credentials. The second layer employs Checkov to scan Terraform code against security and compliance policies — such as CIS Benchmarks and PCI-DSS — flagging misconfigurations like open S3 buckets or disabled encryption. The third and deepest layer uses Terratest to run actual cloud deployments in isolated environments, validate results, and tear down resources, ensuring modules work end-to-end. The article recommends running all three layers in sequence within a CI/CD pipeline, failing fast on cheaper checks before reaching the more time-consuming and costly integration tests.

AgentPostmortem launches public registry to document and learn from AI agent failures

A developer has built AgentPostmortem, a publicly searchable registry cataloguing real-world AI agent failures such as deleted databases, misdirected emails, and unexpected cloud bills. The platform, available at agentpostmortem.com, was created to address the lack of any structured, shared record of AI agent incidents — a gap that allows the same mistakes to repeat across teams. Submissions are structured with fields covering the agent involved, the prompt given, outcome, damage severity, and estimated financial cost, and can be made anonymously or with attribution. Each approved case is assigned a permanent identifier in the format APM-XXXX, enabling it to be cited and referenced over time. All submissions go through moderation and PII redaction before publication, with the project drawing inspiration from aviation safety boards and software postmortem culture.
