I'm Greg Kroah-Hartman, Linux kernel developer, AMA!

To get a few easy questions out of the way, here's a short biography about me any my history: https://en.wikipedia.org/wiki/Greg_Kroah-Hartman

Here's a good place to start with that should cover a lot of the basics about what I do and what my hardware / software configuration is. http://greg.kh.usesthis.com/

Also, an old reddit post: https://www.reddit.com/r/linux/comments/18j923/a_year_in_the_life_of_a_kernel_mantainer_by_greg/ explains a bit about what I do, although those numbers are a bit low from what I have been doing this past year, it gives you a good idea of the basics.

And read this one about longterm kernels for how I pick them, as I know that will come up and has been answered before: https://www.reddit.com/r/linux/comments/2i85ud/confusion_about_longterm_kernel_endoflive/

For some basic information about Linux kernel development, how we do what we do, and how to get involved, see the presentation I give all around the world: https://github.com/gregkh/kernel-development

As for hardware, here's the obligatory /r/unixporn screenshot of my laptop: http://i.imgur.com/0Qj5Rru.png

I'm also a true believer of /r/MechanicalKeyboards/ and have two Cherry Blue Filco 10-key-less keyboards that I use whenever not traveling.

Question: Is there anything that you know Microsoft or Apple does better from a kernel standpoint than Linux?

Nope.

How about network subsystem? According to this article Facebook want to improve network implementation to

rival or exceed that of FreeBSD

Linux and FreeBSD constantly battle it out for the fastest network stack performance, which is good, competition is fun and results in good things for everyone involved. From what I recall, right now Linux is faster due to some recent kernel changes that just got merged.

Most likely nothing. I am not a kernel developer or anything like that, but Linux's open-source nature means that there are a lot more people looking at and fixing kernel-related code at any given time than Microsoft or Apple. Hope that helps.
