It's probably the ugliest shirt in the world... but it can make you "invisible" to AI's eyes

SAPO Notícias5 September 2026 at 13:00

Researchers have developed a specific visual pattern that, when printed on a shirt, can fool computer vision artificial intelligence systems, causing the person wearing it to either not be detected or be confused with the background. The pattern exploits so-called "adversarial examples," which are visual perturbations specifically designed to manipulate the functioning of machine learning algorithms.

The principle behind the technique is not magic or real invisibility, but rather a deliberate exploitation of the weaknesses and limitations of AI-based detection systems. These systems analyze visual patterns and, when they encounter certain combinations of colors, textures, or shapes, may fail to recognize an object or person present in the image.

The shirt has been nicknamed "probably the ugliest in the world" due to its deliberately unpleasant and chaotic design, which would not be something someone would choose to wear for aesthetic reasons. This strange appearance is precisely what makes the pattern effective, as it makes it difficult for computer vision algorithms to identify human presence in the scene.

The research raises important questions about the security and privacy of artificial intelligence-based surveillance technologies, showing that these systems can be vulnerable to relatively simple manipulations. While some see this as a threat to security, others argue that the technique can be used to protect individual privacy in the face of increasing digital surveillance.

C++ on macOS: how to compile native code and which language to choose

Developing in C++ on macOS is accessible thanks to Apple Clang and LLVM integration, allowing quick setup via Command Line Tools without needing the full Xcode. The environment offers native compilation for ARM64 and exclusive tools like xcrun, otool, and LLDB, although it presents differences compared to Linux, such as the Mach-O format and incompatibilities with specific GNU libraries. The article highlights that, despite Swift being the preferred language for new Apple applications, C++ remains essential for high-performance contexts and can interoperate with Swift, ensuring flexibility for developers.

Manufacturers warn: do not put hot food in the refrigerator and these are the reasons

Appliance manufacturers such as Bosch and LG warn that placing very hot food in the refrigerator can compromise the appliance's efficiency and food safety. When hot food is introduced, the interior temperature rises quickly, forcing the compressor to work longer to recover the cold, which increases energy consumption. Additionally, the steam and moisture released can cause condensation and ice formation. The recommendation is to let food cool briefly, divide it into small, shallow containers, and refrigerate it within a maximum of two hours to prevent the proliferation of microorganisms in the temperature danger zone.
