If you’re working with data stored on a remote server, you might not want to (or even have the space to) copy data to your local file system when you work on it. Instead, we can use SSHFS to mount a remote file system via SSH, allowing us to read and write data on the remote file system without manually copying files.

Dealing with multiple compilers
I don’t know you, but when I am compiling a complicated program and everything goes straightforward I feel a mixture of joy and surprise. Let’s face it, compiling can be quite frustrating, and if you need to compile something relatively old, chances are that you will spend hours and hours trying to understand the compiler error messages.
Several such compiler errors, that in many cases can be quite convoluted, tell you that your program requires an older version, so you first need to install it. I am going to assume that you have sudo rights, otherwise, we will be playing the game of compiling a compiler, something that I recommend you to do at least and at most once in your life.
In common Linux distributions like Ubuntu, installing an older compiler is as easy as using apt or yum:
#Ubuntu
$ sudo apt install build-essential
$ sudo apt install gcc-7 g++-7Linux Horror Stories and Protection Spells (Volume I)
Don’t get me wrong. I love Linux. After many years of using it, I ended up appreciating how flexible, potent, and even beautiful it is. However, using Linux has never been a bed of roses and every single Linux user that I know has had to deal with many problems since the very beginning. Indeed, I still remember how frustrating installing my first Linux machine was, especially after realizing that my network card was not working. Had I given up, I would never have written this post.
Although many of the problems that I faced while using Linux are related to updates and drivers (how painful NVidia drivers updates can be, I will write another post about that in the future), I must recognize that on many other occasions I was the only one responsible for such problems. Consequently, I want to warn the reader against a couple of those mistakes I made in the past and provide some tips about how to deal with them.

On the Virtues of the Command Line
Wind the clock back about 50 years, and you would have found the DSKY interface—with a display (DS) and keyboard (KY)—quite familiar. It was frontend to the guidance computer used on the Apollo missions, that ultimately allowed Neil Armstrong to utter that celebrated, “One small step for [a] man, one giant leap for mankind.” The device effectively used a command line.
