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

🔘Practice, as a noun, can be the reality of doing something, rather than the theory.
🔜It sounded like a good plan but in practice, it was terrible.
🔜Your idea works in theory. Let's see if it works in practice.
🔘Practice can be used to describe a custom or tradition.
🔜It's common practice to tip taxi drivers and hairdressers in the UK.
🔜Shaking hands before and after a business meeting is good practice.
🔘We can also use practice to describe an activity that we do regularly.
🔜I enjoy football practice because I love football and I see my friends.
🔜I have to go now. I have band practice this evening.

After many years of inaction, Google has finally released an update for Google Keep ⚹¹ that adds the necessary text formatting functions (i.e. Rich Text Editing or WYSIWYG ⚹²), although not everything — you won’t be able to cross out text. But they are already promising to add version history, which is already something.
Btw even so, "Keep" sucks in terms of functionality and UX, but it's ads-free and fast, so...

⚡️"Yangi O'zbekiston" universitetining bir guruh 1-bosqich talabalari "Inno Technopark"ga tashrif buyurib, uning sharoitlari va imkoniyatlari bilan tanishishgani shaxsan meni quvontirdi.
Negaki, 1-bosqichdanoq amaliy jarayonlarga kirishishlari, kelajakdagi loyihalarda hamkorlik qilishga kelishuvlari💡talabalar uchun juda ham katta maktab bo'lib xizmat qiladi🔥
Izlanish va harakatdan to'xtamang, aziz talabalar❗️

⚡️I was personally pleased that a group of first-year students of the "New Uzbekistan" University visited Inno Technopark and gotacquainted with its conditions and opportunities.
Because from the first-year, entering practical processes, dealing to cooperate in future projects will serve as a foundation for students🔥
