Programmer and rider
I have been using Odoo for years to generate invoices for my little IT business. I don’t use any features that cost money. I am working a web store for my wife and have been playing with erpnext. It is written in Python / Javascript and can be installed on your own servers. I has a lot of features that cost in Odoo but are free and looks like it is easer to modify.
I started as a sysadmin in 1995 and started programming not long after that. I spent most my time in a shell and vim, started writing python all in vim. Then I took on a project that was a graphical application for windows and OS X. It was a rewrite of a windows visual basic app that we did not have the source for, so now good opportunity to write a multi platform application.
I wrote that program in python/pyQt3. Started on linux (which it also ran on) decided to look at IDE’s to help with pyQt I found Eric3. It made writing the first app and many after a lot easier.
So moved on from there a few years later and I use Jetbrains Pycharm commercial if I am writing anything bigger then a quick script I will do it in Pycharm.
Some of the things I like in Pycharm.
I strongly recommend looking at IDE’s start with Kdev and see where it goes also try the trial version of Jetbrains Clion. https://www.jetbrains.com/clion/
It feels like a lot of extra work to learn an IDE but it pays in productivity. Watch some videos on Clion.
It was suggested to peruse a big list of projects that might work for you. They pre package a huge amount of open source projects to run on say AWS in their own linux distro. If you find a project that looks interesting you can go to that projects website and look at docs and stuff. Then run that project how you want.
