At the end of 2020 CentOS announced it would end support at the end of 2021, which sent shockwaves everywhere. Developers and users alike rejected it — even CentOS's founder started the Rocky Linux project that same month to build the next CentOS. Red Hat immediately adjusted course, publishing a post on its official blog on January 20, 2021.
Exited just means the container has stopped. The argument is always about the number that follows — 125, 126, 127, 128, 130, 137, 143. Here's where those numbers actually come from.
DDoS attacks are painful for individuals and for small and medium internet companies alike — even some large enterprises struggle with them. Here's my own take on how Cloudflare, a top-tier CDN and security vendor, absorbs DDoS attacks.
CentOS 8 support ends in 2021. CentOS 7, as the long-term support release, will continue to be supported until its own lifecycle ends, and CentOS Stream becomes the focus. At the end of 2021 CentOS 8 stops being maintained, while CentOS 7 stays supported until 2024.
The last post was about choosing a network. This one is about choosing and configuring a server. There are many types of cloud servers, each aimed at a different scenario; I'm only describing my own, so weigh it against your actual situation.

Download sites were very popular several years ago, but because bandwidth and traffic were expensive, many download sites began hotlinking — visitors click download on someone else's page but use my server's traffic, causing huge bandwidth theft. So hotlink protection is a required course for download sites.
Linus Torvalds announced the release of Linux 5.7 on the kernel mailing list. In his release announcement he commented: "So last week we were fairly calm, with no screams of 'let's drag out one more rc'. Fingers crossed — hopefully we won't have another situation like in 5.6, where a wifi regression landed at the last minute."
Huawei Mobile Search's AspiegelBot crawler was recently found by webmasters scraping site info at high frequency. This AspiegelBot crawler mainly simulates an Android phone to scrape, and its UA identifier doesn't mark which company the crawler belongs to — clearly not wanting to be discovered. Later webmasters dug deeper and found the crawler belongs to AspiegelBot, an Irish subsidiary under Huawei Search; many small sites were directly scraped to a standstill.
Many students often use the kill command to kill processes in daily Linux use. Some use kill directly, some use kill -9, some use kill -3. What do they mean and what's the difference? Today we'll learn about the kill command and signals in Linux.
