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 #linux#triks

https://lnkd.in/e25HNh7A Alhamdulillah, I finished writing this book in few days. I wrote this book to help my friends: Nurkhankyzy Aiya, Acute myeloid leukemia (AML). and all those children who are fighting for their lives. Why is the book called that? AIYA MMD - means Attack and Introduction or (Android and IOS), start Your Adventure in Mobile Malware Development. also AIYA means AIYA Nurkhankyzy. I will be very happy if this book helps at least one person to gain knowledge and learn the science of cybersecurity. The book is mostly practice oriented. Of course the book is not as big as my previous works, this is because firstly I needed to urgently start a fundraising campaign for the Aiya and secondly many things remain confidential (NDA) Mobile malware - it's a constantly evolving battlefield. What you learned here is just the beginning. Tools change, defenses adapt, but the mindset stays the same: think like the adversary to build stronger defenses. This book is dedicated to my wife, Laura, and my children, Yerzhan and Munira. I would like to express my deep gratitude to my friends and colleagues. Special thanks to #Russian#hacking#community, Medet Turin 2600.kz, BlackIce #hackerspace from Almaty (Kazakhstan) and my friends from Middle East countries: Kingdom of Bahrain, Kingdom of Saudi Arabia, UAE. All examples are practical cases for educational and research purposes only.
