50% coding would also be a good target .. :P

I wouldn't be so harsh. If you are young, and if you breathe, drink and eat your product, this could be awesome. None of that lasts forever, of course, but if it happens - what a time to be alive! Not a place for everyone, indeed, and not conventional.

If, on the other hand, you are only interested in the product, and/or you have other stuff to take care of, that would be Hell on Earth for you.

zsh, i3, ssh, openvpn, pidgin, tmux, vim, firefox, vlc - about everything i need all 6hr working day long

if i want to shortcut communication i simply call mates via dialthrough or skype

I get very little of "real" work during regular hours, most of it goes in meetings, code reviews and of course communication. I code during the off hours essentially two jobs i guess, one I love(coding) makes the other(management) bearable .

> If it works for you, I see no problem

There's a reason why 80-90% of the wealthy/developed countries make it illegal to overwork people (even if the worker would be willing to work)
