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/

The message was not authentic, with the real Zelenskiy soon denying the claim on his official Telegram channel, but the incident highlighted a major problem: disinformation quickly spreads unchecked on the encrypted app. At the start of 2018, the company attempted to launch an Initial Coin Offering (ICO) which would enable it to enable payments (and earn the cash that comes from doing so). The initial signals were promising, especially given Telegram’s user base is already fairly crypto-savvy. It raised an initial tranche of cash – worth more than a billion dollars – to help develop the coin before opening sales to the public. Unfortunately, third-party sales of coins bought in those initial fundraising rounds raised the ire of the SEC, which brought the hammer down on the whole operation. In 2020, officials ordered Telegram to pay a fine of $18.5 million and hand back much of the cash that it had raised. Unlike Silicon Valley giants such as Facebook and Twitter, which run very public anti-disinformation programs, Brooking said: "Telegram is famously lax or absent in its content moderation policy." This ability to mix the public and the private, as well as the ability to use bots to engage with users has proved to be problematic. In early 2021, a database selling phone numbers pulled from Facebook was selling numbers for $20 per lookup. Similarly, security researchers found a network of deepfake bots on the platform that were generating images of people submitted by users to create non-consensual imagery, some of which involved children. The SC urges the public to refer to the SC’s I nvestor Alert List before investing. The list contains details of unauthorised websites, investment products, companies and individuals. Members of the public who suspect that they have been approached by unauthorised firms or individuals offering schemes that promise unrealistic returns
