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

🙈 After the ban on accepting organic waste, Bali authorities faced an unexpected consequence: residents began massively burning trash right in their own yards
ℹ️ The decision to restrict organic waste intake was made to accelerate the transition to village-level waste processing systems. Now the island’s largest landfill only accepts non-organic and residual waste. The reason is critical overload: up to 65% of Bali’s waste is organic with high moisture content, leading to methane emissions, unpleasant odors, and rapid overfilling of the site.
🔥 However, in practice, the ban has triggered a wave of uncontrolled waste burning. Lacking sufficient recycling infrastructure, local residents have resorted to the simplest method of disposal – fire.
#rules@BaliNews
🌱 Bali’s main landfill stopped taking organic waste (April 2026) and will fully close by August
👮♀️ Police are monitoring the site, but short-term issues like illegal dumping and river pollution may increase during the transition.
🚮 Tourists: you might notice more trash in some areas – travel responsibly.

🪧Bali installs signs with rules of behavior on the island
📰 The Department of Tourism of Bali province is concerned about the number of violations of the rules of behavior on the island by tourists. Now it is intensifying the installation of information signs with infographics explaining the rules of behavior on the island – Do's and Don'ts.
📍 The plan is to install these signs at 10 key locations in Kuta, Changgu, Seminyak, Uluwatu, Tanah Lote and Bedugul where the chance of reading the rules will be high.
🤞 This is expected to reduce the number of violations so often committed by foreign tourists.
What Do's should be followed first of all?

👮♂️Governor to take firm and tough action against foreign tourists who behave badly while in Bali
📰 The statements come after an American national was arrested and deported after going on a rampage in a hospital on the island under the influence of drugs.
🇺🇸 The 27-year-old US citizen, known by his initials MM, tested positive for drugs, though was deported from Indonesia without criminal prosecution as ‘no evidence’ was found to charge him with drug possession.
❌ He has been added to the blacklist and will be denied entry to Indonesia in the future.
