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

New report cites evidence of alleged military assistance to RSF from #Ethiopian base, raising regional security concerns
A new report by the #Yale School of Public Health’s Humanitarian Research Lab (#HRL) says it has found “high confidence” evidence of activity consistent with military assistance by Ethiopia to Sudan’s Rapid Support Forces (#RSF), raising concerns about escalating regional insecurity.
The report, published on 8 April, is based on satellite imagery and open-source data collected between late December 2025 and late March 2026.
It concludes that such activity is taking place at an Ethiopian National Defense Force (#ENDF) base in #Asosa town, in Ethiopia’s #Benishangul-Gumuz region.
HRL says its assessment is based on five key indicators observed at the Asosa base and not found at 14 other ENDF installations reviewed for comparison.
One of the central findings is the repeated presence of non-military commercial car carriers........

A legal group submitted to the #UN the most thorough legal analysis of Israel's actions concluding it is committing genocide against Palestinians in Gaza.
This is probably the most complete report to date that demonstrates how #Israel's attacks on #Palestinians in #Gaza meet the legal definition of #genocide.
It's a 100-page report, by legal experts at #Boston University School of Law, #Cornell Law School, #Yale Law School, and others.
The report's conclusion:
"Israel has committed the #genocidal acts of #killing, causing serious harm to, and inflicting conditions of life calculated to bring about the physical #destruction of #Palestinians in #Gaza, a protected group that forms a substantial part of the Palestinian people.
These #genocidal acts have been motivated by the requisite genocidal intent, as evidenced in this report by the statements of #Israeli leaders, the character of the State and its forces’ conduct against and relating to Palestinians in Gaza, and the direct nexus between them."
