The article discusses AFL++ for fuzz testing C and C++ programs, revealing defects missed by previous fuzz testing. It provides tips on how to pick a program, including using persistent mode and customizing ASan options.
Researchers at the University of Illinois Urbana-Champaign have developed a 3D thermal invisibility cloak that can hide complex objects from infrared cameras while protecting them from extreme temperatures. The device guides heat around an object, making it appear invisible to thermal imaging from virtually any direction.
Mathematicians are unhappy with AI's impact, feeling it undervalues their work and creates a culture of "business as usual" where novelty is prioritized over understanding. The author argues that mathematicians should focus on broader programs and structural understanding rather than relying solely on AI to answer existing questions.
Copper is a programming language that I use as a replacement to C. The main differences are: Minimalism is the most important feature, the language is intended to be simple so that someone with limited brain power such as me could fully understand it. The syntax is simple, almost everything is explicit and most constructs are common.
Claudio Grossi, an Italian farmer, discovered a 100-year-old sack of seeds that produced a unique and ancient wheat variety called "grano del miracolo" or "miracle grain." This hardy wheat has been shown to have nutritional benefits and is more resilient to droughts and extreme weather events.

The user discusses the limitations of using an electric car's battery for backup power during grid outages, citing various manufacturers' restrictions on bidirectional charging. They consider alternative options, including a smaller emergency-only battery and Enphase's planned bidirectional EV charger, but are hesitant to wait due to uncertainty about its release date.
The author wrote two long stories using groff, a typesetting system, and then converted the second one to Markdown for easier editing. They used macros to format the text and created a distraction-free writing environment with Vim.
Seoul Viosys develops rare-earth-free white light emitter, a micro-LED chip as small as 10µm. The technology is expected to create a new $60bn market in augmented reality and AI data communications within five years.
Two Brazilian lawyers were fined for intentionally embedding a hidden command in a court filing to manipulate an AI system, potentially undermining justice. The case may be the first globally to address intentional manipulation of a court's AI system through prompt injection.
A critical Linux kernel vulnerability (CVE-2026-98432) allows a remote, unauthenticated peer to reach and crash the system. The fix is available in kernels 5.10.272, 5.15.223, and others; users should install the fixed kernel and reboot as soon as possible to prevent exploitation by attackers who can run arbitrary commands as root without credentials or user interaction on servers with a ...
Researchers have identified a persistent 1-minute oscillation in grid-frequency time series worldwide, which they attribute to clock-synchronized control software in digitally controlled energy devices. This signal can propagate across multiple voltage levels and contribute to wear and tear on hydropower systems.
A multi-agent harness for programming problems was developed using a Memdoor workflow, achieving a mean score of 9.8 out of 10 on LiveCodeBench Hard problems. The harness uses five roles and a repair worker to solve the problems through file-based communication without relying on human intervention or models.
The author conducted a benchmark to compare the performance of various JavaScript frameworks, including Next.js, Nuxt, SvelteKit, and Angular. The results showed that most frameworks were similar in terms of development time and cost, but some were more expensive than others.
Parchment paper, a key tool for baking and cooking, has its origins in ancient animal skin used for writing. The modern version was developed in the 19th century with the addition of silicone, which enhances its heat resistance and non-stick properties.
