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 #linux#triks

🚨 BREAKING NEWS 🚨 🔴 Biden's Vietnam Press Conference Cut Short 🔴 In a shocking display of incompetence, the Biden administration once again revealed their true colors during President Joe Biden's press conference in Vietnam. As Biden stumbled through his answers, White House staff abruptly ended the event, cutting his microphone and playing jazz music to drown out his ramblings. While attempting to address stability and global access to change, Biden was interrupted by his press secretary, Karine Jean-Pierre, who hastily declared an end to the conference. Astonishingly, Biden continued speaking, unaware that his mic had been muted. The bizarre scene escalated further as jazz music filled the room, leaving the 80-year-old president confused and still attempting to respond to questions. As the music grew louder, Biden reluctantly retreated from the stage, whispering and shuffling behind a black curtain. Throughout the 26-minute engagement, he even used the infamous phrase, "lying dog-faced pony soldier," contributing to his already questionable credibility. This incident comes after Biden's whirlwind trip, where he attended the G20 Leaders' Summit in India before hastily jetting off to Vietnam. Instead of displaying strength and leadership, Biden's performance only highlighted his lack of stamina and clarity. His joke about not knowing if it was morning or night further emphasizes the worrying state of his mental acuity. To make matters worse, Biden shared a convoluted story from a John Wayne movie that had little relevance to the pressing issues at hand. It seems that Biden's administration is more focused on theatrics than addressing the concerns of the American people. This latest debacle only adds to the mounting evidence that Biden is nothing more than a puppet of America's deep state, lacking the competence and independence to lead our nation effectively. The American people deserve better than this. #BidenAdministration#Incompetence#DeepStatePuppet
