As the letter ‘d’ in the name of “systemd-networkd” infers for “daemon” mode, this service is meant to manage all network stuff in the background rather than “NetworkManager” is for setting network graphically up with the help of its GUI.
I wanted to switch to “systemd-networkd” in my Ubuntu Linux machine for the sake of getting some kind of Linux experience and also getting rid of the distracting message of the “NetworkManager” — alerting about its failure on registering the network. For that reason, after searching, I came up with a set of relatively easy commands to handle.
The core concept of this transition is very basic, and you need just turn off one service and turn on another service by using “systemctl” — this is for controlling and managing “systemd” services. …
I recently have developed four types of linked-lists, namely:
My approach was, TDD (test-driven development). In that manner, I first appropriated the overall necessary tests to measure whether my upcoming developments meet all the requirements and what anticipated from the functionality of the functions for the total linked-lists or not. …
Upon the completion of my React web app that was initially made by create-react-app, I tried to deploy it on Heroku, but it basically seemed a bit difficult. To get some clues for resolving that, as googling has been always the primitive choice, so I did it. Searching resulted in a ton of diverse ideas and methods, including adding some metadata in the package.json, setting a Procfile to incorporating Express server inside the application. Eventually, I learned that those techniques were to some extent antipattern, even so, the core concepts of them were helpful.
Then, I came up with a method that is perfectly in compliance with the patterns and works pretty well, and I already employed it in my app. In a nutshell, it is to put the server and the client/s — in my case, it was a React web app — into two distinct folders, where the client-folder should displace inside the server-folder. Both folders need to have their own package.json which are different, but interrelated. …
