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

🔴 Today I suggest you plunge into the past and visit the mill, which is 130 years old! Pflaumer's Mill is a wooden giant on the banks of the Volga On the left bank of the Volga, a little away from the city of Nikolaevsk, a huge wooden steam mill of the late XIX - early XX century has been standing for more than a century. It is called the "Pfläumer Mill" in honor of the German settler Friedrich Pfläumer. They say that he built it in 1906, although according to other sources he was only a co-owner and manager.

🔴 Today I would like to invite you to a most unusual temple. The Temple of All Religions in Kazan This temple is not about prayers. Services are not held here, and believers are not gathered here. It is more of a museum, a symbol, a fantasy about world religions.

🔴 Moscow has many different architectural styles and trends in construction. You can, for example, find a piece of Italy. Tarasov's mansion is a true oasis of the Italian Renaissance amidst the bustle of Moscow. It was built at the beginning of the 20th century: the project was ordered by Gavriil Tarasov, a Moscow merchant. The idea was ambitious: Gabriel wanted a house that looked like a palazzo in Vicenza (a city in Italy), and architect Zholtovsky did not disappoint. He created a true Italian palace that you would hardly expect in the very center of Moscow — marble, columns, arches.

🔴 I invite you to a walk around amazing Karelia. Sortavala is a Karelian city with a European soul and a long history. A bit of history The city was officially founded in 1468, although people lived here long before that date. The first settlers were the Sami, an ancient people of the North. Archaeologists find bone needles, arrowheads, and the remains of settlements of the II millennium BC on the islands. Throughout its history, Sortavala has changed hands more than once: from Russia to Sweden, back to Russia, then to Finland and back again. Each era has left its traces in the appearance of the city.
