Как Минэкономразвития и Центробанк запланировали стагнацию на все обозримое будущее — и где лежит их ошибкаПоследние 18 лет средний рост ВВП в нашей стране ниже 2% и это официальные данные Росстата. Основную часть из этих лет правительственные ведомства сначала отчитываются главе государства о том, что ВВП то ли падал, то ли стагнировал. Потом делают прогнозы на будущее, из которых следует, что дальше будет как бы лучше, но заметят это не... Read more ›

Отдавая контрактному производству полный комплект Gerber-файлов и оригинальных прошивок, разработчик часто рискует столкнуться с «атакой третьей смены» — бесконтрольным выпуском нелегальных клонов устройства. Есть ли варианты защиты? Казалось бы, нет, однако... Есть... физика кремния, физически неклонируемые микродефекты кремния (PUF) и неповторимость литографии внутри FPGA. И это можно использовать как уникальный отпечаток устройства.В этой статье я расскажу, как заставить наноструктурные особенности FPGA Read more ›

Привет Хабр! Большинство современных метеостанций для умного дома бесполезны без интернета или локального MQTT-брокера. Пропал Wi-Fi — данные о микроклимате за последние сутки испарились вместе с перезагрузкой контроллера. Готовые логгеры стоят дорого, а их проприетарное ПО не дает доступа к сырым данным. Мне требовалось максимально дешевое и автономное решение — классический "черный ящик" для квартиры и балкона. Устройство должно пережить внезапное отключение света, не потерять ни одной точки замера и... Read more ›

Heavy marijuana smoking may raise the risk of lung cancer and several head and neck cancers, according to growing research, but many important questions remain unanswered. Scientists are still trying to determine how much marijuana use is enough to significantly increase cancer risk. Edibles have not been linked to lung cancer so far, while the long-term effects of vaping marijuana and secondhand marijuana smoke are still being investigated. Read more ›

A newly discovered underwater volcanic eruption north of Papua New Guinea is unfolding in one of the world's most poorly mapped ocean basins. Satellites have spotted steam plumes, ash, thermal hotspots, and huge floating pumice rafts, suggesting magma is rising surprisingly close to the surface. Scientists are now watching closely to see if the eruption creates a new island, offering a rare opportunity to observe the birth of new land... Read more ›

A new study found that dietary fiber can determine whether beneficial intestinal worms help reduce inflammation or become essentially inactive. With plenty of fiber, the worms remained healthy and supported an anti-inflammatory response, while a low-fiber diet pushed them into a hibernation-like state that eliminated those benefits. Researchers also found that fiber-rich diets promoted healthier gut bacteria, whereas Western-style diets reduced microbial diversity and encouraged less desirable microbes. Read more ›

A detailed independent study found that SpaceX's Starship is every bit as revolutionary as expected, while revealing both its impressive capabilities and its biggest remaining hurdles. It also introduces an ambitious European rocket concept that could offer a very different route to affordable super heavy launches. Read more ›

Many of the body's biggest flaws are the result of evolution building on old designs instead of starting over. Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that worked well enough for survival but still leave us prone to pain, injury, and disease. Structures like the appendix and ear muscles also remain because they were never harmful enough for evolution to eliminate. Together, these features tell... Read more ›
