Raspberry Pi 4, a very nice “open source” surprise

logo_smallFor a long time, I am in favor of open source programs. My scientific work is done under Linux with GNU FORTRAN and some Python. Reports are written with Latex and spreadsheets are done with Libreoffice. Graphics are made with GNU-plot and my documentation system is Wikipedia. But I have to agree that I needed a lot of times an expensive LINUX consultant to get the thing running. And in some cases, the expert was not able to get it running because the relevant computer component has not a good driver for LINUX.

71RJj8SmQGL._SX355_The Raspberry Pi on the other hand is a cheap computer, developed to run with LINUX, in this case the Debian based Raspbian. Moreover, it is meant as a didactic tool for students. I bought a Raspberry Pi 4 with 4GB RAM, transformator, 32GB SD-card, which serves as hard disk, a small touch screen  and a HDMI cable for 100€ all-in. This is indeed cheap.

My colleague (a Windows expert) assembled the small computer and installed Raspbian on the SD-card in about 30 minutes and  it was already running. He also installed RDP (remote desktop) to have access from another PC or tablet or mobile phone when a second monitor, keyboard and mouse are not available.

I installed  without any knowledge GNU FORTRAN, a Python development environment, a keyboard on the small screen, LATEX with Texmaker, GNU-plot, SAMBA (to allow Windows explorer in the Raspberry Pi), Midnight Commander, Apache web server and WORDPRESS together with the MySQL database with the help of the well documented Raspbian site but without an expensive LINUX consultant. I program my Raspberry with a Windows laptop running MobaXterm.

And indeed, everything is working perfect, it is a nice surprise I never expected for 100€. I advise to install like me the small screen for (25€ ) because it allows to type a new Wifi code without monitor, keyboard and mouse. After making a copy of the SD-card, I can share my work on a new Raspberry Pi 4 without any installation.
