Интересная хардкорная статья "Patch-Gapping the Google Container-Optimized OS for $0", как исследователь нашел патч для kernel баги и понял что патч еще не применен в дистрибутиве ОС для контейнерных окружений от Google.

You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”
