Efficiently delete a million files on Linux servers

Efficiently delete a million files on Linux servers

Blog

You know you love programming, but it has become boring, frustrating and even painful. You see your coworkers busily at work around you, and you don’t understand how they can stand it anymore. So what happened? How do you move on? How do you keep motivated? Understanding Your Intrinsic Motivations You might not loathe programming yet. But if you’re having doubts about your job, and you’re not doing anything about it, it can only go downwards. Why do you go to work? Like (almost) everyone, your first motivation is probably money. You need money to make a living. However I bet that more money won’t…

In some cases, DNS can be convoluted and complicated.  Let’s talk about Domain Name System (DNS) services. When you need to access a website, you type the domain name, such as www.google.com, into the web browser instead of typing an IP address. A conversion happens between www.google.com to 172.217.12.46, an IP, which designated to a device on the Internet.
