So we ran'MiniMax M2,'Kimi K2 Thinking, and'GLM-4.6'against three vulnerabilities: a payment race condition, JWT algorithm confusion, and an FFmpeg command injection to see how they compare. A Reader Asked Why Not Test Open-Weight Models Kimi K2 Thinking'from Moonshot AI We ran all tests in Kilo Code on the same base Node.js project (TypeScript + Hono) with all required dependencies pre-installed. For each vulnerability, we created a single file containing only the vulnerable code and prompted the model: "Fix this security vulnerability," without describing the vulnerability type or giving extra context. Why we did this:'Real-world use cases involve vague prompts. This approach was different from what many benchmarking providers do, where they provide (often) detailed prompts to test output. Testing GLM-4.6 in Kilo Code with the standardized…...

AI-powered PDF tagging offers developers a way to automate structure detection, semantic labeling, and layout interpretation'with accuracy improving every year. Accessibility laws like WCAG and Section 508 require structured PDFs. Developers building platforms for publishing, document management, education, or enterprise workflows need to ensure PDF outputs are accessible by default. Without proper tags, screen readers cannot interpret headings, lists, reading order, or images. If you've done it manually, you know how time-consuming and error-prone it is. Manual tagging breaks down at scale. Problems developers often face: AI models analyze page elements and apply logic to generate meaningful structure. They perform tasks such as: Think of it as an engine that "reads" a PDF visually, similar to how a human would'but much faster. " Document…...

2+ min ago (232+ words) The diagram below breaks down nine core patterns you'll encounter: Client-Server Architecture remains the foundation of web applications'clients connect through the internet, typically via load balancers and CDNs, to reach backend services. Layered Architecture separates concerns vertically: Presentation Layer handles the UI, Business Logic Layer processes rules and workflows, and Data Access Layer manages persistence. Pipes and Filter processes data through a sequential chain'information flows from a source through multiple transformation filters before reaching its final destination. Domain Driven Design organizes complex systems around bounded contexts. In the example shown, Catalog, Order, Fulfillment, and Billing contexts each own their domain while communicating across boundaries. Monolithic Architecture bundles everything into a single deployable unit'web layer, business components, and a shared database. Simple to start, but scaling gets tricky. Microservices Architecture takes the opposite approach. Independent services each maintain their own database,…...

9+ min ago (619+ words) A prototype by two students is redefining reforestation with precision planting. A pair of 19-year-old innovators from Portugal has developed a new all-terrain reforestation robot designed to plant trees in wildfire-damaged areas that are too steep or dangerous for people or heavy machinery to enter. The robot, called Trovador, is a six-legged, AI-enabled planting system created by college students Marta Bernardino and Sebasti'o Mendon'a, who began the project after witnessing repeated forest loss near their homes outside Lisbon. Portugal is one of Europe's most wildfire-affected countries. A 2024 study by University of Lisbon atmospheric scientist Carlos C. DaCamara found that more than 1.2 million acres burned between 1980 and 2023, equivalent to 54 percent of its territory. In 2017 alone, the country lost 32,000 acres of tree cover, with wildfires responsible for 75 percent of that destruction. Many of these fires occur in steep, rugged terrain that volunteers and…...

Oskar Graulund Lentz Rasmussen, Erik Kjellgren, and Peter Reinholdt, all from University of Southern Denmark, alongside Stephan P. A. Sauer from University of Copenhagen, Sonia Coriani from Technical University of Denmark, and Karl Michael Ziems from University of Southampton, now present a significant step towards reliable quantum calculations. Their research introduces a new, cost-effective method for mitigating these errors, specifically designed for a class of quantum circuits known as tiled Ans'tze. This technique dramatically reduces the…...

So, it's a good time to get back and analyze the fresh LLVM 21. Although pretty much all C++ developers have at least heard of LLVM, we'll make a brief disclaimer. LLVM is a massive open-source umbrella project that contains a huge set of various tools for writing optimizing compilers of any complexity. We checked only the 253d18d032bb commit from the main branch without Clang, libc, lldb, and other components, and focused on High- and Medium-severity errors detected by the general-purpose diagnostic rules. The commit links are provided to help verify and fix detected errors. They aren't intended to compromise or undermine the work of the contributors. Well, let's get started! Let's start our investigation with a…...
