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

The average lifespan of a goldfish (Carassius auratus) is 10-15 years, with some varieties living into their thirties when properly cared for. However, one male goldfish named Tish (1956-1999) lived to the remarkable age of 43, making him the world’s oldest goldfish ever. [Read more] @googlefactss #FunFact#AnimalFacts#fish

Cats have three types of color-detecting cones, just like humans, but see colors less vividly. They perceive blues and greens well, but reds and pinks may appear grayish. Their vision excels at detecting subtle movement, especially in dim light. 🔵🟢🌙 [Read more] [See here] @googlefactss#CatVision#AnimalFacts#Science

Beavers build dams to protect themselves from predators like bears and wolves. They live in lodges, not in the dam itself, on deep ponds made by the dams. These lodges have underwater entrances, so beavers can safely enter and leave without being seen. The pond keeps land animals away and the lodge is a dry home and food storage. 🦫🌊🌿@googlefactss#Beavers#Wildlife#Nature#AnimalFacts

Llamas spit to protect themselves, keep their place, or show power. Males spit in fights over females. Females spit to stop males. They also spit when annoyed or mistreated. Llama spit has saliva and partly digested food. It can fly up to 10 meters (33 feet). 🦙💨 [Source] @googlefactss#Llamas#AnimalFacts#Spitting

Penguins have several group names. A group in water is called a “raft.” On land, it is called a “waddle.” A large group of penguins living or breeding together is called a “colony.” The place where they gather to breed is also called a “rookery.” 🐧🌊🏝️🐣 [Read more] @googlefactss #Penguins#AnimalFacts#Wildlife#DidYouKnow

Elephants can “listen” with their feet. Their foot pads have special nerve receptors that detect ground vibrations, including very low-frequency infrasound. Vibrations from other elephants’ rumbles or footsteps travel through the ground. Signals move through their bodies to the brain. Vibrations can also reach the inner ear through bone conduction. This helps elephants communicate over long distances and sense distant movement. 🐘🌍👣🔊 [Read more] @googlefactss #Elephants#AnimalFacts#Wildlife#Nature#Science#DidYouKnow

🐾 Capybaras are the world's largest rodents — social, semi-aquatic animals that live in groups in South America. They're so calm that other animals often sit on them, and they can even sleep underwater! 🌊 [Learn more] @googlefactss#Capybara#AnimalFacts#Nature#Rodents#Wildlife

Snow leopards are sometimes seen biting or holding their own tails. Scientists think they may do this to stay warm in cold mountain habitats or to play. A snow leopard’s long, thick tail also helps it balance on steep rocky cliffs and can wrap around its body like a blanket. 🐆❄️🐾 [Read more 1] [Read more 2] @googlefactss #snowleopard#animalfacts#wildlife#naturefacts#bigcats#didyouknow
