FSR 4 is supposed to only work on RX 9000 series GPUs, but modders were quick to figure out how to run it on older RDNA graphics cards when AMD accidentally published the entire source code on GitHub. Several users have since tested their GPUs with tweaked DLLs, with all results pointing toward improved visuals at the cost of worse FPS. Read more ›

"I'm stunned by the illogicality of others, and they are stunned by the fact that I'm a robot." This phrase perfectly describes the peculiarities of my interaction with the world around me. I'm the same robot. Or an alien. I can only guess how I seem to others. But now I know for sure that others consider me at least strange. This is completely mutual. Many actions of people around...

В августе, благодаря нашей песочнице, была предотвращена атака на российские организации с применением нового вредоносного кода. Изначально мы предположили, что это массовый фишинг с серверов злоумышленников, который каждый день можно встретить на почте любой организации. Но оказалось, что отправитель письма вполне легитимный: он был скомпрометирован злоумышленниками, нацеленными на российские оборонные и промышленные организации.Хакеры использовали сложную схему сокрытия вредоносной нагрузки в архивах-поли Read more ›

Всем привет! Это вновь Илья Смирнов, архитектор решений из Cloud.ru. В прошлой статье мы рассмотрели традиционные подходы к масштабированию подов и узлов кластера Kubernetes. Но остался нерешенным вопрос — как масштабировать приложение по событиям из внешней системы? Ведь мы хотим, чтобы каждое новое сообщение в очереди RabbitMQ масштабировало нагрузку вверх, реализовать event-driven подход и масштабировать приложение не по метрикам утилизации ресурсов, а по факту появления новых событий от внешних систем..

Спустя два года после дебюта iPhone самым продаваемым телефоном в США было не чудо Apple с сенсорным экраном. Это был BlackBerry Curve. Вы спросите, как такое возможно? Разве iPhone не убил телефоны с клавиатурами? На самом деле, история чуть сложнее.Да, действительно, BlackBerry как бренд не пережил переход на телефоны с сенсорными экранами, но iPhone были не единственной причиной такого перехода.
