Мониторинг «здесь и сейчас»: используем потоки событий JDK Flight Recorder
JDK Flight Recorder (JFR) — это диагностическая подсистема, встроенная в JVM. В основе JFR лежит очень простая идея, но вокруг нее выросла разнообразная экосистема решений, позволяющих решать широкий спектр задач. В данной статье я хочу сфокусироваться на одном аспекте технологии JFR — потоковой обработке событий. Потоковая обработка появилась в JDK 14 в виде Flight Recorder Event Streaming API и позволяет прикладному коду обрабатывать события JFR с минимальной задержкой. 📌 Подробнее:https://habr.com/ru/companies/axiomjdk/articles/917766/

That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future. The news also helped traders look past another report showing decades-high inflation and shake off some of the volatility from recent sessions. The Bureau of Labor Statistics' February Consumer Price Index (CPI) this week showed another surge in prices even before Russia escalated its attacks in Ukraine. The headline CPI — soaring 7.9% over last year — underscored the sticky inflationary pressures reverberating across the U.S. economy, with everything from groceries to rents and airline fares getting more expensive for everyday consumers. "Your messages about the movement of the enemy through the official chatbot … bring new trophies every day," the government agency tweeted. The War on Fakes channel has repeatedly attempted to push conspiracies that footage from Ukraine is somehow being falsified. One post on the channel from February 24 claimed without evidence that a widely viewed photo of a Ukrainian woman injured in an airstrike in the city of Chuhuiv was doctored and that the woman was seen in a different photo days later without injuries. The post, which has over 600,000 views, also baselessly claimed that the woman's blood was actually makeup or grape juice. "There are a lot of things that Telegram could have been doing this whole time. And they know exactly what they are and they've chosen not to do them. That's why I don't trust them," she said.
