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

🌎 Giant clouds called molecular clouds are where new stars are born. These clouds, made mostly of hydrogen gas, can stretch for hundreds of light-years. The Orion Molecular Cloud Complex, one of the closest such regions, is located about 1,350 light-years from Earth and is home to thousands of young stars. ✨ #astronomy⚡#stars⚡#nebula 👉subscribe Interesting Planet 👉more Channels ​

🪐 In the galaxy NGC 1999, astronomers observed a mysterious, dark patch once believed to be a dense cloud of cosmic dust blocking light. However, further study revealed this region is actually a rare "hole" in the nebula—an empty cavity punched through the glowing gas by powerful stellar winds from young, massive stars, making it a striking example of cosmic sculpting at work. ✨ #nebula⚡#phenomena⚡#astronomy⚡#nasa⚡#galaxy⚡#stars⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries ​

🪐 In the Carina Nebula, the massive star Eta Carinae is surrounded by strange, expanding clouds known as the Homunculus Nebula—vast lobes of gas and dust hurled into space by a series of explosive outbursts in the 19th century. These violent eruptions have sculpted one of the most complex and enigmatic structures ever observed, with glowing filaments and mysterious hidden cavities still being revealed by the Hubble Space Telescope. ✨ #EtaCarinae⚡#nebula⚡#mysteries 👉subscribe Universe Mysteries

🪐 The Egg Nebula (CRL 2688) in Cygnus glows with haunting, layered arcs of dust and gas, shaped by fierce stellar winds from a dying central star. These concentric shells, illuminated by starlight scattered through dense clouds, reveal a dramatic portrait of a Sun-like star in its brief, enigmatic transition into a planetary nebula. ✨ #nebula⚡#stars⚡#transformation⚡#nasa⚡#galaxy⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 In the star-forming region of the Orion Nebula, astronomers have identified "proplyds"—dense disks of gas and dust swirling around newborn stars. These proplyds are being sculpted by fierce ultraviolet radiation from nearby massive stars, their bright comet-like tails pointing away from blazing giants such as Theta1 Orionis C. ✨ #Orion⚡#proplyds⚡#nebula 👉subscribe Universe Mysteries

🪐 The Boomerang Nebula in the constellation Centaurus is the coldest known place in the universe, with temperatures dropping to a chilling -272°C—colder than the cosmic microwave background itself. This young planetary nebula expels gas at incredible speeds, creating a ghostly, double-lobed shape that shrouds its dying central star in frigid mystery. ✨ #BoomerangNebula⚡#coldest⚡#nebula 👉subscribe Universe Mysteries

🪐 The star AG Carinae, located about 20,000 light-years away, is a rare example of a "luminous blue variable"—an unstable giant star that can erupt in massive outbursts, shedding huge shells of gas and dust. AG Carinae shines millions of times brighter than the Sun and is surrounded by a glowing nebula created by its violent eruptions, making it one of the most volatile and spectacular stars in our galaxy. ✨ #unusualstars⚡#stellareruption⚡#nebula⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 In the center of the galaxy NGC 2392, also known as the "Eskimo Nebula," astronomers have detected fast, energetic jets of gas blasting outwards at speeds of over 200 kilometers per second. These jets, launched by the dying central star, punch through surrounding shells of glowing gas, creating intricate, layered patterns that make this nebula one of the most visually stunning and mysterious cosmic objects observed by the Hubble Space Telescope. ✨ #nebula⚡#jets⚡#emission⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries ​
