Back in 2022, surrounded by colleagues who were infused with "open source scepticism", I wrote "Open Source in Enterprise Environments - Where Are We Now and What Is Our Way Forward?" https://nxdomain.no/~peter/opensource_enterprise_notes.html as an explainer.
Hopefully a useful thing for others too, with links therein #freesofware #opensource #enterprise #openbsd #freebsd #netbsd #linux
Since the original came out, I have made updates here and there, and added references to some newer material.
You could see "EU CRA: It's Later Than You Think, Time to Engineer Up!" https://nxdomain.no/~peter/eu_cra_its_later_than_you_think_time_to_engineer_up.html as a further development in response to the real world (or at least the EU parts) moving forward.
One important aspect /all/ people overlook, including you:
Aircraft carriers are /simple/ compared to software.
Building a modern air-craft carrier takes merely one million different stock-numbers.
/bin/bash is 200k lines
Last I looked SystemD was north of 1M
All of FreeBSD is 26 million lines.
Linux kernel alone is 36 million lines.
Ohh, and also this old rule of thumb:
"Well written code typically has one bug for every thousand lines."
Quote away, people need to understand it.
PS: I'm pretty sure I also told you in a talk in Bergen some years ago, with nice illustrative pictures :-)
