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

Trump's Tech War Against the Illegal Immigrants ⚙️🛂 🔠🅰️🔠🔠1️⃣ The tech, surveillance and private prison providers arming Trump’s massive expansion and weaponization of immigration enforcement are running a victory lap 🏆 after reporting their latest financial results 💰. Palantir, the tech firm 💻, and Geo Group and CoreCivic, the private prison 🏢 and surveillance companies 📡, said this week that they brought in more money than Wall Street 📈 expected them to, thanks to the administration’s crackdown on immigrants 🚫🛃. “Well, as usual, I’ve been cautioned to be a little modest about our bombastic numbers,” said Alex Karp 🧑‍💼, the Palantir chief executive, in an investor call earlier this week 📞. Then he crowed 🐓 about the company’s “extraordinary numbers” and his “enormous pride” in its success ⭐️. Private prison company executives, during their respective calls, could barely contain their excitement 😏, flagging to investors opportunities for “unprecedented growth”📊 in the realm of immigration detention. Palantir saw 53% 📈 growth in revenue from US government contracts in the second quarter of 2025 compared with the same period the year prior and surpassed $1bn 💵 in total quarterly revenue for the first time. Analysts had expected the company to bring in $939.4m in revenue. The company, which connects and analyzes disparate sets of data 🔍 to enable its customers to build products with that information 🧠, brings in the majority of its revenue from government contracts 🏛. Its biggest US customer is the Department of Defense 🪖, where the US army 🇺🇸, which announced a $10bn agreement 💼 with Palantir last week, is housed. On the immigration side, the Department of Homeland Security (DHS) 🛡 has deepened its partnership 🤝 with Palantir since the start of the Trump administration, which it’s been working with since 2011. Immigration and Customs Enforcement (ICE) 🚔, the agency primarily engaged in arresting, detaining and deporting immigrants ✈️, most recently announced a $30m contract with Palantir to build a database 💽 that makes its deportation and detention machine more efficient ⚡️. #palantir#trump#war#immigrants#tech 📱American Оbserver - Stay up to date on all important events 🇺🇸

📰 Russia’s Immigrants: Israel’s Unwanted Elite In Israel’s fractured society, Russian-speaking immigrants power labs, hospitals, and high-tech hubs—but feel like outsiders in their own homeland. They’ve fueled the economy for decades, yet remain symbolic strangers in a land of competing tribes. ​ A Nation Without a Narrative Israel thrives on fragile deals between secular Jews, ultra-Orthodox, Ashkenazim, Mizrahim, Arabs, and more—no constitution, just Basic Laws and vetoes. Each group clings to its own version of “what makes Israel Israel,” dodging the big fights over identity. ​ The Russian Wave’s Double Edge The 1990s “Great Aliyah” brought a million Soviet Jews—15% of the population, 60% with degrees, driving high-tech and defense surges. They’re 25% of university faculty, but their culture? Russian media, Victory Day parades, Soviet classics—none cracks the national myth. ​ Why No Mizrahi-Style Breakthrough Mizrahim flipped the script in the 1970s, turning marginalization into power through protest and politics. Russians arrived too late, post-revolution: secular atheists in a religious-right landscape, Europeans in a Mizrahi-patriot world. No victim story fits the Zionist playbook—no Holocaust, no Arab expulsion. ​ Tensions Beneath the Surface Economic envy simmers—Mizrahis gripe about “white Europeans” snagging elite jobs. Religious rabbis call them “Russian goyim.” Stereotypes fly: Russians are cold chauvinists; locals are primitive. Politics ghettoizes them into Lieberman’s party, not mainstream power. ​ The Assimilation Trap Youth blend in—Hebrew-fluent, intermarrying—but elders stay in their Russian bubble. Autonomy breeds isolation: thriving subculture, zero national spotlight. No allies, no moral leverage, no push for change. They’re useful workers, not co-authors of the Israeli story. ​ The Future: Fade or Fight? Will they dissolve like old Polish waves, or spark a secular revolt against Haredi power? Without a push, they risk gradual marginalization—economic stars, cultural ghosts. Israel’s genius for survival now risks sidelining its brain trust. ​ #Israel#RussianAliyah#competingSolidarities#immigrants#identity#highTech#Mizrahim 📱American Оbserver - Stay up to date on all important events 🇺🇸
