В Linux стандартными средствами можно использовать часть оперативной памяти как диск. Для этого требуется указать тип монтирования tmpfs в команде mount
mount -t tmpfs -o size=5G tmpfs /mnt/ram
Теперь путь /mnt/ram можно использовать как обычный каталог. Для чего это может быть нужно?
▫️ Скорость работы с таким каталогом выше чем многие SSD и тем более HDD.
▫️ Если у вас очень быстрый SSD на NVMe M.2 то такой способ особо не прибавит вам скорости, но поможет сохранить ресурс SSD когда требуется обрабатывать очень много мелких файлов и оперативка позволяет выделить нужный объем.
▫️ Оперативка это энергозависимая память, поэтому выключении питания все файлы безвозвратно теряются. Такой "non persistent" каталог гарантирует удаление временных файлов.
Я написал небольшой скрипт для условного теста и сравнения скорости копирования файлов между SSD и RAM.
Вот мои результаты:
Single File Size: 30.0Gb
ssd > ssd: 0:00:12.850 / 2.3Gb/s
sdd > ram: 0:00:06.453 / 4.6Gb/s
ram > ram: 0:00:06.995 / 4.3Gb/s
ram > sdd: 0:00:06.217 / 4.8Gb/s
Dir size: 32.7Gb, File count: 11127
ssd > ssd: 0:00:15.063 / 2.2Gb/s
sdd > ram: 0:00:08.486 / 3.9Gb/s
ram > ram: 0:00:08.032 / 4.1Gb/s
ram > sdd: 0:00:07.026 / 4.7Gb/s
Скрипт для теста ↗️
На моём железе прирост скорости ~2x. Плюс экономия ресурса SSD.
В Windows такой фишки по умолчанию нет, но обязательно найдутся аналогичные решения

AIGP 2025 Update: Streamlining AI Governance Certification for Real-World Impact
The IAPP has unveiled the latest version of its AIGP Body of Knowledge (BoK), effective for exams through February 2, 2025, offering a clearer, more flexible, and practical approach to AI governance certification. Simplified to four domains, the update places new emphasis on foundational principles, ensuring that certification aligns with the most relevant and influential legal frameworks worldwide.
This streamlined version is highly practical, designed to address the current responsibilities AI governance professionals encounter, not merely theoretical questions. Furthermore, Domains III and IV now separate the roles of developers and deployers, a crucial distinction reflecting how laws and standards are evolving in the field.
By balancing legal and technical insights, the new AIGP BoK solidifies its standing as the essential credential for those committed to responsible AI governance.

ISO Releases Free AI Governance Standard
The International Organization for Standardization (ISO), a prominent NGO known for creating industry standards, has made the important ISO/IEC 22989 standard publicly available for free. This standard addresses a wide range of AI governance topics, providing valuable guidelines for the responsible development and deployment of AI technologies.
ISO/IEC 22989 covers essential aspects of AI governance, including ethical considerations, risk management, and compliance requirements. It provides standardized concepts and terminology to help stakeholders understand and adopt AI technology effectively. This document is designed for a wide audience, including both experts and non-practitioners, offering insights into AI’s interdisciplinary nature, which encompasses computer science, data science, natural sciences, humanities, mathematics, and social sciences.
By making this standard freely accessible, ISO aims to promote the widespread adoption of responsible AI practices, ensuring that AI systems are trustworthy, robust, resilient, reliable, accurate, safe, secure, and private.
You can find ISO/IEC 22989 and other publicly avalable standards here.
