Ask HN: Can we talk about FreeBSD vs. Linux? 12 years ago
I just want to know about differences in design and unbiased identification of strengths and weaknesses.
There's no such thing as an unbiased identification of strengths and weaknesses, especially when it comes to monoliths like operating systems.
You say you're not interested in arguing about which system is better -- and I believe you -- but you're also asking for argument about which system is better, in list form. Heck, even your title has a versus in it.
That said, I join you in looking for a concise source of information about FreeBSD's design and usage in the wild contrasted with Linux.
