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

#Ethiopia: Report warns of arbitrary detentions, growing restrictions on media in Addis Ababa
-------
A new report by Human Rights First has raised concerns over alleged arbitrary detentions and increasing restrictions on media in #Addis_Ababa, particularly during periods of major international events.
The report, titled “Situational Analysis of Human Rights in Addis Ababa,” states that security forces carried out “pre-emptive detentions” across several parts of the capital without due process.
According to the findings, detentions were recorded in sub-cities including #Yeka, #Bole, and #Akaki_Kality, where individuals were held for more than a week without being charged or appearing before court.
In addition, the report highlighted what it described as a growing pattern of restrictive actions against media between 2025 and early 2026.

News: Report tracks #UAE-linked cargo flights to #Ethiopian military base amid regional power struggle
A cargo aircraft previously linked to the supply of weapons to armed groups in #Sudan has conducted multiple flights to Ethiopia in recent weeks, according to an exclusive investigation by the UK-based outlet Middle East Eye (MEE), raising questions about Ethiopia’s role in intensifying regional rivalries tied to the war in Sudan.
MEE reported that an Antonov An-124 cargo plane operated by UAE-based Maximus Air, and allegedly linked to Emirati military logistics, made repeated flights between #Abu_Dhabi and #Harar_Meda airbase, the main base of the Ethiopian Air Force.
Flight-tracking data reviewed by the outlet shows at least four trips to Harar Meda between 3 and 17 January, including one flight that later continued to Addis Abeba’s #Bole International Airport before departing for #Europe and #Asia.
While the purpose of the flights remains unclear...
