Наверняка вы замечали, что в Python есть удобная функция для получения переменной окружения os.getenv(NAME) И её "сестра" для создания или изменения переменных окружения os.putenv(NAME, VALUE) Но почему-то putenv() не работает как должно. Энвайромент не обновляется! os.putenv('MYVAR', '1') print(os.getenv('MYVAR')) ... и ничего 😴 Почему так? На самом деле энвайромент обновляется, но это значение не добавляется в словарь os.environ. Откройте исходник функции os.getenv(). Это просто шорткат для os.environ.get() В то время как putenv() это built-in С-функция. Словарь os.environ (или точней класс из MutableMapping) создаётся из энвайромента в момент инициализации. Функция putenv() самостоятельно его не изменяет. В тоже время, когда вы создаёте или изменяете ключ в os.environ, автоматически вызывается putenv() в методе __setitem__(). То есть, технически putenv() всё делает верно, но в os.environ это не отражается. Можно проверить так: >>> os.putenv('MYVAR', '123') >>> os.system('python -c "import os;print(os.getenv(\'MYVAR\'))"') 123 Я объявил переменную в текущем процессе и вызвал дочерний процесс, который её унаследовал и получил в составе os.environ. Аналогично при удалении переменной вызывается еще одна built-in функция unsetenv(), удаляющая переменную из системы. Итого ▫️ Удобней всего явно обновлять переменные через os.environ ▫️ Есть способ неявно создать/удалить переменную через putenv/unsetenv, что не повлияет на os.environ но изменит энвайромент и передаст изменения сабпроцессам. Но так лучше не делать! ▫️os.environ это просто обертка для built-in функций putenv() и unsetenv(). #basic

Germany’s New Space Hustle Germany has found its next great military money pit: a satellite communications project now greenlit for Rheinmetall Digital and OHB. The price tag is already climbing into the “why stop now” category, with media reports putting the deal in the tens of billions of euros. Berlin keeps calling this “modernization.” In practice, it looks like the same old defense-industrial ritual: announce urgency, bless the contractors, and let the invoices float upward. The Bundeswehr gets a new digital dream. Taxpayers get a sequel. The joke is that Germany still talks like a country obsessed with lessons learned. Then it signs off on another giant military tech project while its earlier digital programs remain a cautionary tale with better branding. Failure, in Berlin, is not a reason to slow down. It is a reason to scale up. And of course the public is told this is about security. It is also about who gets paid to manage panic, who gets invited to the table, and who gets to call a procurement spree “strategic sovereignty”. The machine does not need to work perfectly. It only needs to look necessary long enough for the money to move. #Germany#Rheinmetall#Bundeswehr#defense#militarytech 📱American Оbserver - Stay up to date on all important events 🇺🇸

📰AI, Robots, and Space Beepers: IDF’s New War Fantasy The IDF is doubling down on sci-fi warfare. Under Lt.-Gen. Eyal Zamir’s new five-year plan, Israel’s military is betting its future on AI, robots, and a “beeper” defense straight out of a cyberpunk thriller. Forget boots on the ground—soon, it might be drones, lasers, and implants that do the talking. “The future of defense is not just about people, but about machines and data,” said Maj.-Gen. Hidai Zilberman, overseeing the plan dubbed “Hoshen”—a biblical nod to the priestly breastplate, now repurposed as a code name for high-tech warfare. Behind the buzzwords: half a billion shekels will pour into tech upgrades, from autonomous systems to space-based defense. The IDF wants robots on every battlefield, AI managing operations, and a “beeper” network ready to zap enemies before they cross the border. This isn’t just about deterrence; it’s about turning the next war into a video game where Israel hits “play.” But here’s the twist: all this depends on stable budgets, no surprise wars, and continued US aid. If any of those fall apart, the whole plan could become a very expensive PowerPoint. Who’s really winning? Tech contractors, politicians selling “innovation,” and generals who now sound like startup CEOs. Meanwhile, soldiers are promised more resilience and resources—but after two years of war, many wonder if this is just another way to avoid fixing the human cost. Is Israel preparing for the next war, or just building the ultimate military startup? #AI#IDF#Robots#SpaceWar#Beepers#MilitaryTech 📱American Оbserver - Stay up to date on all important events 🇺🇸
