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

The anonymous Monero $XMR crypt was tracked by the Finnish authorities — which was previously considered impossible
However, they do not disclose details about their analysis of the #Monero network in the case of the hacking of #Vastaamo — most likely there are nuances that reveal the true essence, and this is just a screaming headline.
Haveno
https://github.com/haveno-dex/haveno
Private and decentralized way to #exchange#Monero for national currencies or other #cryptocurrencies. Haveno uses peer-to-peer networking and multi-signature escrow to facilitate trading without a trusted third party custodian. Disputes can be resolved using non-custodial arbitration. Everything is built around Monero and Tor.
Haveno is the Esperanto word for "Harbor". The project is stewarded by a core Team, currently formed by 2 people: ErCiccione and Woodser. See the FAQ in the wiki for more information about the project
https://github.com/haveno-dex/haveno/wiki/FAQ
Haveno is still work in progress. There are no binaries available at this stage. If you want to test Haveno you have to compile it first (see https://github.com/haveno-dex/haveno/blob/master/docs/installing.md).
Status of the project
At the moment Haveno is only a Proof of Concept. It's already possible to initiate crypto <-> XMR and fiat <-> XMR trades, but the platform still needs a lot of work before being available for public use.

🚀 Monero and Zcash Expected to Launch on Mainnet Soon
Monero (XMR) is anticipated to go live on the mainnet within one to two months, according to Foresight News. The chain client pull request has successfully passed simulation testing. To address privacy observation issues with XMR, THORChain plans to create a dedicated Asgard vault composed of all validator nodes.
In parallel, Bittensor (TAO) is being developed alongside Monero, aiming for a simultaneous launch. Additionally, Zcash (ZEC) is expected to launch on the mainnet by the end of April.
