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

The question posed to men in the US and Russia was: "Would you fully support your wife?"
🔻In Russia it depends on several issues: husband's salary (if it is high, wife is likely not much into work, but keeps the house and takes care of kids), wife's ambitions, the age and social status of the respondents.
🔻But on average, the situation when husband fully supports his wife is not rare in Russia.
❓I'm curious if it is common in your country for the husband to fully support his wife (not girlfriend!), or is it more of a 50/50 split on expenses?

💛 8 July — Day of Family, Love and Fidelity 🕊
Today, Russia celebrates a heartfelt and meaningful holiday — the Day of Family, Love and Fidelity, which is observed in honour of Saints Peter and Fevronia of Murom, revered as the patron saints of marriage and family happiness in the Orthodox tradition.
This day serves as a reminder of the timeless values that form the foundation of any society: love, fidelity, mutual understanding, and care for one another. It unites generations, strengthens family ties, and inspires the preservation of traditions and their transmission to future generations.
🌿 The symbol of the holiday is the daisy, representing purity, sincerity, and faithful love. On this day, it is customary to give daisies, hold family gatherings, and congratulate couples — especially those who have shared many years together in harmony.
The Consulate General of Russia in Cape Town extends its warmest congratulations to Russian compatriots and friends of Russia on this special occasion and wishes every family peace, happiness, and enduring love!
