Debian GNU/Hurd.

See also https://bbs.archlinux.org/viewtopic.php?id=248330 — our OP started a thread there about Arch Hurd but it was quickly TGN'd and turned into a social thread, which was nice.

seL4 ftw!

I just want to know more. If the hurd kernel is old and useless then why Debian released a new of it!!

Debian doesn't release the hurd kernel, they just offer a Debian distribution based on it. Why? Because they can. Debian is a non-profit, so they don't have to look at what's commercial or not.

What's TGN?

The Arch forums have a section called Topics Going Nowhere which is used as a storage area for threads of little or no technical value, when a thread is sent there the moderators say it has been TGN'n. It is only accessible by members and so is out of reach of the search engines, which is why the link is dead for you.

the hurd kernel

GNU Hurd uses the Mach microkernel. Ask a search engine about it, looks like you could do with the practice

Maybe because it is not useless?? You concluded from "it is not very useful to many users right now" that it is "useless". That's like if a farmer inquired how useful the rain outside might be for his crops... and someone told him that "well it is not raining that much now", and the farmer would conclude from that that "it is not raining at all/rain is useless". It just logically does not follow...

Also remember that it is 0.9, now, and presumably will be called 1.0 when it is "ready"
