“What is the most complex program, application or game you have created on Linux? What programming language did you use?”
It’s not strictly Linux anymore, but I wrote a library (or userspace driver?) in Python that interacts with a ChromeOS Embedded Controller found in Framework Laptops and Chromebooks. The driver part of it interacts with the EC directly over the IO ports, which was originally written for Linux but later ported to FreeBSD and Windows since IO ports aren’t at all OS specific. It can also talk to the
cros_ec_devdriver on Linux if it’s loaded.https://github.com/Steve-Tech/CrOS_EC_Python
I wrote a GUI utility for Framework Laptops too, which also serves as the example for CrOS_EC_Python: https://github.com/Steve-Tech/YAFI
I wrote and maintain a zero-to-working SAP HANA/S4 installer in pure bash.
It takes a redhat compatible from base install to a working, production-ready SAP system in about 5 hours.
It’s like ~9,000 lines of bash
Why does it take 5 hours?
Building a fully functional SAP system just takes that long in raw install time when your process also includes a sufficiently large system copy, and your hardware isn’t bleeding-edge.
It’s a massive application stack
