Сегодня, 21-го февраля днём, на Солнце произошла вспышка. Не очень сильная, но способная серьёзно повлиять на больных и (в особенности) пожилых людей.
Такие события могут приводить к обострению старческого маразма, агрессии, потери связи с реальностью.
Впрочем, иногда подобные симптомы — это просто общее отражение ментального состояния человека.

A Sociological Study of the Official History of the Perceptrons Controversy
In this paper, I analyze the controversy within Artificial Intelligence (AI) which surrounded the `perceptron' project (and neural nets in general) in the late 1950s and early 1960s. I devote particular attention to the proofs and arguments of

Хакерская группировка LAPSUS$, взломавшая недавно Nvidia требует от компании распространения их драйверов по идеологии Open Source (сейчас драйвера проприетарные, с закрытым исходным кодом). Это позволит программистам собирать собственные драйвера с собственными изменениями (например, убрать ограничитель на майнинг) или выпустить драйвера для непопулярных дистрибутивов Linux.
Если компания не пойдет на этот шаг, хакеры обещают в пятницу выложить чертежи и исходники всех чипов Nvidia, в том числе и будущих моделей.

White noise improves learning by modulating activity in dopaminergic midbrain regions and right superior temporal sulcus
Abstract:
In neural systems, information processing can be facilitated by adding an optimal level of white noise. Although this phenomenon, the so-called stochastic resonance, has traditionally been linked with perception, recent evidence indicates that white noise may also exert positive effects on cognitive functions, such as learning and memory. The underlying neural mechanisms, however, remain unclear. Here, on the basis of recent theories, we tested the hypothesis that auditory white noise, when presented during the encoding of scene images, enhances subsequent recognition memory performance and modulates activity within the dopaminergic midbrain (i.e., substantia nigra/ventral tegmental area, SN/VTA). Indeed, in a behavioral experiment, we can show in healthy humans that auditory white noise-but not control sounds, such as a sinus tone-slightly improves recognition memory. In an fMRI experiment, white noise selectively enhances stimulus-driven phasic activity in the SN/VTA and auditory cortex. Moreover, it induces stronger connectivity between SN/VTA and right STS, which, in addition, exhibited a positive correlation with subsequent memory improvement by white noise. Our results suggest that the beneficial effects of auditory white noise on learning depend on dopaminergic neuromodulation and enhanced connectivity between midbrain regions and the STS-a key player in attention modulation. Moreover, they indicate that white noise could be particularly useful to facilitate learning in conditions where changes of the mesolimbic system are causally related to memory deficits including healthy and pathological aging.
