The Domain Name System (DNS) is a system that provided human readable names for computers, services and other resources connected to the internet. Basic records allow to translate a Domain Name (that humans can understand) into an IP Address (that computer understand for routing).
W1203 is important
If you have been using pylint tool to check the format of your Python code you may have encounterd the rule W1203: logging-fstring-interpolation but you didn't really understand why it's important.
The warning looks like :
path/to/my/file.py:37:4: W1203: Use lazy % formatting in logging functions (logging-fstring-interpolation)
It appears when you are using the Python logging library. On the pylint documentation about this rule it is said that you shouldn't use f-string formated strings.
I'm currently hosting some private web services accessible from internet. In order to protect those apps, I needed a very secure way to protect the access to them.
As you may already know, there are tons of bots that continuously scan all public internet IPs for potential vulnerabilities. From open ports, insecure web services or security breach. There are private organizations that allow to discover those vulnerabilities like Shodan. In my particular case, this is the only information that they could collect from my IP gateway :
First of all I'm not a web engineer and I hate web development. There are too many framework to work with (ReactJS, Angular, jquery, ...). Javascript asynchronous system is a pain to manage at large scale. And dependencies maintainability is too much for me (yes, I'm talking about you npm). I'm not a web designer either so HTML/CSS are the enemy (mostly because I don't know how to use them at their full potentials).
This is pretty much why I quit web development in the first place and became a SysOps engineer.
