41 TB/day from Oracle to Postgres Pro without stopping the source system — not theory, but numbers from our latest tests. We broke the migration into three stages: fast initial load, CDC from redo logs, and validation, and wrapped them into ProGate. In this article, we’ll explain how the pipeline works, why we chose Go, and where the bottlenecks hide. Read more

A July combat training exercise involved a satellite dish-style antenna that "could fire enough electromagnetic energy to fry the satellite 22,000 miles away," reports the Washington Post. But "Instead, the salvo would be more covert — millisecond pulses of energy that would subtly disrupt the satellite's signals, which U.S. military forces were using to communicate in the Pacific Ocean." The goal was to disguise the strike as a garbled connection... Read more ›

That metric edges out the previous record from the Bugatti Chiron Super Sport 300+, which achieved 304.77 mph in 2019. Officially, the fastest production... Read more ›

An AI-generated image posted by President Trump depicts him buying Intel stock at $20 and selling it at $30 to make a considerable profit. These prices are mostly accurate, given that the real-life purchase occurred at $20.47 per share, and Intel stock reached over $30 just two days ago, although that rise can be attributed to the Nvidia deal instead.

"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...

We take a close look at Percona, Cybertec/EDB, Pangolin/Fujitsu, and show where you lose performance and reliability, and where you gain flexibility.On top of that, Vasily Bernstein, Deputy head of product development, and Vladimir Abramov, senior security engineer, will share how Postgres Pro Enterprise implements key rotation without rewriting entire tables —...

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?
