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

🇷🇺Russia proposed to open the BRICS grain exchange, which will allow to ensure food security in the association.
President #Putin:
It has been suggested to open the BRICS grain exchange that will facilitate the formation of fair and predictable price indicators for products and primary produce, considering its particular role in ensuring food security. The implementation of this initiative will help protecting national markets from negative external interference, speculations and attempts to cause the food shortage artificially.

@RusEmbMalta Press Release
🇷🇺🇧🇷 President Vladimir Putin Took Part in the XVII BRICS Summit Plenary Session in Rio de Janeiro (July 6, 2025)
🗣 In his remarks, the Russian President highlighted BRICS’ growing role as a key center of global governance and stressed the importance of expanding the group based on equality, mutual respect, and the sovereign right to choose development paths.
📊 According to IMF data for 2025, BRICS accounts for 40% of the global economy, with a combined GDP (PPP) exceeding $77 trillion – far ahead of the G7’s $57 trillion.
💬Key points from President Putin’s speech:
– The world is undergoing tectonic shifts. The outdated unipolar system is giving way to a just multipolar order.
– Expanding the use of national currencies is vital. In 2024, over 90% of Russia’s transactions with BRICS partners were in the ruble and friendly currencies.
– BRICS is building an open cooperation architecture with the Global South and East – 10 countries already hold BRICS Partner status.
– Traditional values, equality, and civilizational diversity are becoming the foundation of a new globalization model.
– Developing an independent BRICS payment and settlement system is a strategic priority.
📄The Rio de Janeiro Declaration was adopted at the summit under the theme “Strengthening Global South Cooperation for a More Inclusive and Sustainable Governance.”
It includes:
✅ A reaffirmation of commitment to multilateralism and comprehensive UN reform, including Security Council expansion to better represent developing countries
✅ Strong condemnation of unilateral sanctions and the June 2025 military strikes against Iran
✅ Condemnation of terrorist attacks on Russian civilian infrastructure (May–June 2025)
✅ Support for the Palestinian people’s right to self-determination
✅ Emphasis on “African solutions to African problems” as a basis for conflict resolution on the continent
