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

Myth: The tongue is divided up into specific areas that are solely responsible for sensing certain tastes (e.g., sweet at the tip, bitter at the back) Fact: The tongue's receptor cells that identify the molecules underlying the basic tastes (sweet, sour, salt, bitter and umami) are distributed on taste buds all over the tongue although some areas may be slightly more sensitive to certain flavors.. @googlefactss#humanbody#nowyouknow#mythbusted [read more...]

Myth: Glass flows over time, making old windows thicker at the bottom. Fact: Glass is an amorphous solid, meaning its atoms are arranged randomly, not in a pattern like crystals. It stays solid at all normal temperatures and only softens above 600°C (1112°F). Old windows are thicker at the bottom because of how they were made, not because glass moves. 🔥🌡️ [Read more] @googlefactss #GlassFacts#Science#MythBusted#Heat

Viking helmets with horns are -mostly- a myth. Only one authentic Viking helmet exists, without horns. Horned helmets appear in art linked to berserkers—fierce warriors who likely wore them for rituals, not battle. Horns would be impractical in combat, and no historical records mention Vikings wearing them. Real Viking helmets were simple and functional. ⚔️🛡️ [More🪖] @googlefactss #Vikings#History#MythBusted#Berserkers#Archaeology

❄️ Hot water does NOT freeze faster than cold water. While a rare phenomenon called the Mpemba effect suggests it can happen under specific conditions, cold water almost always freezes first.

The idea that skinny people have fast metabolisms is a myth. Metabolism depends largely on muscle mass—more muscle means higher energy use. Skinny people usually have less muscle, so their metabolism is often slower. Weight and appearance don’t reliably show metabolism speed.

Myth: opposums sleep while hanging by their tails. Fact: Opossums do not hang upside down by their tails 🐾. Their tails are strong for gripping branches and carrying nesting materials but can’t hold their full weight for long. Young opossums might dangle briefly but don’t sleep that way. They “play possum” by pretending to be dead when scared, which helps protect them from predators. 🌙🐾🌳 [Read more] @googlefactss#PossumFacts#AnimalBehavior#NatureFacts#MythBusted#DisneyWasWrong
