❓ Как и где Spring ищет бины?

Spring ищет бины с помощью сканирования классов в указанных пакетах, используя аннотации (@Component, @Service, @Repository, @Controller и кастомные с @Component внутри).

Сканирование начинается с пакета, переданного в @ComponentScan или (по умолчанию) из того, где находится @SpringBootApplication (которая включает @ComponentScan).

Если бин не помечен аннотацией, его можно зарегистрировать вручную через @Bean в @Configuration-классе, BeanDefinitionRegistry или XML-конфиг.

Newly uncovered hack campaign in Telegram

The campaign, which security firm Check Point has named Rampant Kitten, comprises two main components, one for Windows and the other for Android. Rampant Kitten’s objective is to steal Telegram messages, passwords, and two-factor authentication codes sent by SMS and then also take screenshots and record sounds within earshot of an infected phone, the researchers said in a post published on Friday.

How to Buy Bitcoin?

Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
