Samsung says the reddish center tint seen on some Galaxy S26 Ultra displays is a software issue, not hardware. A complimentary calibration can fix it at official service centers with same-day service, and Samsung is preparing a remote software update to apply the calibration without a service visit; details on the update timeline will be announced.
DriftGuard, a third‑party calibration tool, claims to permanently calibrate any Xbox controller—wired or wireless—by storing calibration data in the controller memory, delivering an unpatchable fix for stick drift across Xbox generations. It expands DriftGuard’s prior PS controller support, with free browser access and a Steam version planned for the near future; Microsoft’s official Xbox Accessories recalibration tool exists but is limited to select controllers, and real‑world results may vary.
MIT CSAIL researchers propose RLCR (Reinforcement Learning with Calibration Rewards), using the Brier Score to penalize over-confident wrong answers and reward well-calibrated uncertainty, leading to more reliable LLM outputs and the ability to admit when they don’t know—potentially increasing safety for high-stakes applications.
A practical guide to maximizing Hisense TV picture quality using built-in presets and targeted tweaks. It covers one-step options and specific adjustments for live TV, streaming, and gaming, including Auto Picture Mode, HDR Enhancer, Local Dimming, color temperature, gamma, and motion settings, plus options for advanced Calman calibration and saving or resetting custom modes.
NVIDIA unveils Ising, the world’s first open-source family of AI models designed to accelerate quantum processor calibration and quantum-error-correction decoding, delivering up to 2.5x faster performance and 3x higher accuracy. The models run locally, integrate with CUDA-Q and NVQLink, and are already adopted by major labs and universities, with a growing ecosystem of workflows, data, and microservices available on GitHub, Hugging Face, and NVIDIA builds.
A cyberattack on Intoxalock disrupted its breathalyzer calibration services, leaving drivers unable to calibrate their devices and stranded; the company is offering 10‑day calibration extensions and occasional towing, with no disclosed data breach. The WIRED security roundup also covers the FBI resuming purchases of commercial location data, an Iranian-linked hack disrupting Maryland hospitals’ Stryker medical devices, an AI agent security incident at Meta, and the takedown of several botnets used in major cyberattacks.
Hackaday covers Bigcrimping’s BHG-2000, a pin‑compatible DIY replacement for the now unobtainable HSN‑1000 nuclear event detector. The build uses four BPW34S PIN diodes coated to block visible light, aiming to detect the characteristic gamma pulse that signifies a nuclear event, with a two‑stage amp chain to output a warning. Calibration remains unverified without exposure to gamma sources, and the creator is seeking European testers with Cs‑137 or Co‑60 sources. The project is open‑source, and Hackaday cautions that nuclear explosions are best avoided while noting the detector concept could in principle warn of blasts.
The Switch 2's HDR implementation is flawed due to confusing UI and poor default settings, leading to washed-out images. Experts recommend enabling HGIG if supported, adjusting paper white and MaxTML settings, and following calibration tips to improve visual quality.
The Switch 2 supports HDR, but its complex and poorly explained calibration process can lead to washed-out graphics, making it difficult for users to optimize settings and fully enjoy improved visuals.
A DIY project describes creating a calibration target for electron microscopes by depositing gold nanoparticles on silicon slides, enabling precise calibration and repair of the microscope's resolution capabilities.
NASA's Perseverance rover is repeatedly photographing a tiny, intricate maze on a metallic calibration plate on Mars, which is part of the SHERLOC instrument used to search for signs of ancient life. The maze helps calibrate the rover's laser and imaging systems with high precision, and the plate also tests materials for future human missions, blending scientific purpose with hidden storytelling elements.
NASA's Perseverance rover repeatedly photographs a maze on its SHERLOC calibration target, which is used to calibrate its spectroscopic instruments for detecting organic compounds and minerals on Mars. The maze, made of chrome lines on silica glass, helps ensure precise laser focus and positioning, and features a Sherlock Holmes portrait as a fun nod and functional marker. The calibration target also includes materials for testing spacesuit durability and supporting science for future human exploration.
In Overwatch 2, a player was surprised to receive a significant rank progress despite not playing their main role in Competitive mode. The game's latest rank changes include a "soft reset" to players' MMR, leading to adjustments based on performance. The player's confusion was addressed in a Reddit thread, with some users explaining that the game's modifier "Calibration" is responsible for the unexpected rank progress when playing a different role, as it assesses uncertainty and aims to determine the player's true rank.
A low-cost CH32V003 MCU, lacking temperature measurement functionality, can be improvised to include a temperature sensor by measuring the drift between two internal clocks and using it to calibrate a temperature graph. By utilizing the automatic wake-up unit (AWU) and accessing the LSI clock source indirectly, a temperature plot was obtained, although the absolute accuracy of this method may vary per MCU. This crude temperature measurement solution could be sufficient for basic applications.
The European Space Agency (ESA) has developed an artificial star-like light source to test the optical performance of startrackers, which are used by spacecraft to determine their position in space. The test bench, located at ESA's ESTEC technical centre in the Netherlands, combines a rotating table with a single star simulator to simulate the light from a star. The purpose of this facility is to calibrate startrackers in terms of distortion, chromatic aberration, and other optical variables, aiding in spacecraft navigation.
